+ *		in the same area, and rewrite the BBT when any of them are erased.

Subject: [MTD] bast-flash partitions fixup

Ensure the whole device is added if there are no partitions found on the
device, so that at least the flash can be read/written.

Replace some of the constants with their SZ_xxx counterparts

Subject: [MTD] rtc_from4 error status check, disable virtual erase blocks

Added routine to perform extra error status checks on erase and write
failures to determine if errors are correctable.
Added option to prevent JFFS2 from using virtual erase blocks.
Performed minor cleanup on whitespace and comments.

Try larger numbers of chips before smaller
numbers of chips across the bus width.

This means we'll avoid misdetecting a 2 x16 array as 1 x32 if the
high 16-bits happen to read as zeros in the QRY area.

+
+	  The user-programmable Protection Registers contain one-time

+	  erased. Each Protection Register can be accessed multiple times to
+	  program individual bits, as long as the register remains unlocked.
+
+	  Each Protection Register has an associated Lock Register bit. When a
+	  Lock Register bit is programmed, the associated Protection Register
+	  can only be read; it can no longer be programmed. Additionally,
+	  because the Lock Register bits themselves are OTP, when programmed,
+	  Lock Register bits cannot be erased. Therefore, when a Protection
+	  Register is locked, it cannot be unlocked.
+
+	  This feature should therefore be used with extreme care. Any mistake

Subject: [MTD] User interface to Protection Registers

This is implemented using a ioctl to switch the MTD char device into
one of the different OTP "modes", at which point read/write/seek can
operate on the selected OTP area.  Also some extra ioctls to query
for size and lock protection segments or groups.  Some example user
space utilities are provided.

Subject: [JFFS2] Core changes required to support JFFS2-on-Dataflash devices.

DataFlash page-sizes are not a power of two (they're multiples of 528
bytes).  There are a few places in JFFS2 code where sector_size is used
as a bitmask.  A new macro (SECTOR_ADDR) was defined to calculate these
sector addresses. For non-DataFlash devices, the original (faster)
bitmask operation is still used.

In scan.c, the EMPTY_SCAN_SIZE was a constant of 1024.
Since this could be larger than the sector size of the DataFlash, this
is now basically set to MIN(sector_size, 1024).

Addition of a jffs2_is_writebuffered() macro.

From 8f15fd55f9bf266139b10850947e19c4e3f4e9b7 Mon Sep 17 00:00:00 2001
From: Andrew Victor <andrew@sanpeople.com>
Date: Wed, 9 Feb 2005 09:17:45 +0000
Subject: [JFFS2] Add support for JFFS2-on-Dataflash devices.

For Dataflash, can_mark_obsolete = false and the NAND write buffering
code (wbuf.c) is used.

Since the DataFlash chip will automatically erase pages when writing,
the cleanmarkers are not needed - so cleanmarker_oob = false and
cleanmarker_size = 0

DataFlash page-sizes are not a power of two (they're multiples of 528
bytes).  The SECTOR_ADDR macro (added in the previous core patch) is
replaced with a (slower) div/mod version if CONFIG_JFFS2_FS_DATAFLASH is
selected.

From 2f82ce1eb637c06dfc60f095cd1891ae0ba4894c Mon Sep 17 00:00:00 2001

Subject: [JFFS2] Use a single config option for write buffer support

This patch replaces the current CONFIG_JFFS2_FS_NAND, CONFIG_JFFS2_FS_NOR_ECC
and CONFIG_JFFS2_FS_DATAFLASH with a single configuration option -
CONFIG_JFFS2_FS_WRITEBUFFER.

The only functional change of this patch is that the slower div/mod
calculations for SECTOR_ADDR(), PAGE_DIV() and PAGE_MOD() are now always
used when CONFIG_JFFS2_FS_WRITEBUFFER is enabled.

Subject: [MTD] NAND: Allow operation without bad block table

Small bugfix. Sometimes it may be handy not to have bbt.
So, this->bbt might be NULL.

Subject: [MTD] NAND: Read only OOB bytes during bad block scan

When scanning NAND for bad blocks, don't read the whole page, read
only needed OOB bytes instead. Also check the return code of the
nand_read_raw() function. Correctly free the this->bbt array in
case of failure. Tested with Large page NAND.

Fix debugging message.

Subject: [MTD] Fixup probing logic for single 16bit devices

The change to the generic probe to look for the
smallest width of chip first is causing some problems
on boards with a single 16bit device.

The problem seems to be the jedec_match() is truncating
the device-id read from the table to match against the
one read from the hardware, causing a match against the
partial id of some chips with 16bit IDs (such as the
SST39LF160)

This fixes things for my own board, but something may
need to be done if the same problem is exhibited for
chips with an 8bit ID

 driver

This driver does not have as many options but it's easier to maintain.
And, it turns out AMD never shipped boards with different flash densities.

-mode.  This drivers uses the CFI probe and Intel Extended Command Set drivers.
-
-The flash is accessed as follows:
-
-   32 kbyte memory window at 0xb0000-0xb7fff
-   
-   16 bit I/O port (0x22) for some sort of paging.
-
-The single flash device is divided into 3 partition which appear as separate
-MTD devices.
-
-Linux thinks that the I/O port is used by the PIC and hence check_region() will
-always fail.  So we don't do it.  I just hope it doesn't break anything.

Subject: [MTD] ixp2000: Remove port setting code

Setting the slowport to 8-bit mode is something that ought to be
done in the IXP2000 generic code, not in the MTD map driver.  See
the description for ARM patch 2493/1 for an explanation.

http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=2493/1

Now that 2493/1 has been accepted and will be upstream soon, this
doesn't need to be done in the map driver anymore.

Subject: [JFFS2] Fix NOR only compile

Fix the bug that caouses problems when compiling for NOR.
We read  a newly erased block so we don't need to check ECC.

Define jffs2_is_writebuffered as zero if there is no wbuf.

Subject: [MTD] CFI flash locking reorg for XIP

This reworks the XIP locking to make sure no lock primitive is ever
called from XIP disabled paths even if in theory they should not
cause any reschedule.  Relying on the current spinlock implementation
is rather fragile and not especially clean from an abstraction pov.
The recent RT work makes it even more obvious.

map_word_ff() was setting the mapword to ~0UL regardless of the
buswidth of the mapped flash chip. The read_map functions are
buswidth aware and therefor the map_word_equal function failed.

Subject: [MTD] NAND: Reorganize chip locking

The code was wrong in several aspects. The locking order was
inconsistent, the device aquire code did not reset a variable
after a wakeup and the wakeup handling was not working for
applications where multiple chips are sharing a single
hardware controller.
When a hardware controller is available the locking is now
reduced to the hardware controller lock and the waitqueue is
moved to the hardware controller structure in order to avoid
a wake_up_all().

The problem was pointed out by Ben Dooks, who also found the
missing variable reset as main cause for his deadlock problem.

Subject: [PATCH] ARM: 2781/2: PXA27x Standby mode take 2

Patch from Todd Poynor

Add support for PXA27x Standby mode, a low-power mode that retains CPU
and some peripheral state (the existing "sleep" mode is a power-power
mode that retains less state). Activated via:
echo -n standby > /sys/power/state

The omnimeter_defconfig does not define any machines and
seems to have no other support in the current kernel.
This patch removes the config file, as this is the only
thing currently mentioning the ominmeter.

Subject: [PATCH] ARM: replace schedule_timeout() with msleep()

Use msleep() instead of schedule_timeout() to guarantee the task
delays as expected. Neither signals nor wait-queue events are
important at this point in the code, I believe.

Subject: [PATCH] PCI: Increase the number of PCI bus resources

This patch increases the number of resource pointers in the
pci_bus structure. This is needed to store >4 resource ranges
for host bridges and transparent PCI bridges. With this change,
all PCI buses will have more resource pointers, but most PCI
buses will only use the first 3 or 4, the remaining being NULL.
The PCI core already deals with this correctly.

Subject: [PATCH] PCI: handle subtractive decode pci-pci bridge better

With the number of PCI bus resources increased to 8, we can
handle the subtractive decode PCI-PCI bridge like a normal
bridge, taking into account standard PCI-PCI bridge windows
(resources 0-2). This helps to avoid problems with peer-to-peer DMA
behind such bridges, poor performance for MMIO ranges outside bridge
windows and prefetchable vs. non-prefetchable memory issues.

To reflect the fact that such bridges do forward all addresses to
the secondary bus (transparency), remaining bus resources 3-7 are
linked to resources 0-4 of the primary bus. These resources will be
used as fallback by resource management code if allocation from
standard bridge windows fails for some reason.

Subject: [PATCH] PCI: pci_assign_unassigned_resources() on x86

- Add sanity check for io[port,mem]_resource in setup-bus.c. These
  resources look like "free" as they have no parents, but obviously
  we must not touch them.
- In i386.c:pci_allocate_bus_resources(), if a bridge resource cannot be
  allocated for some reason, then clear its flags. This prevents any child
  allocations in this range, so the setup-bus code will work with a clean
  resource sub-tree.
- i386.c:pcibios_enable_resources() doesn't enable bridges, as it checks
  only resources 0-5, which looks like a clear bug to me. I suspect it
  might break hotplug as well in some cases.

Subject: [PATCH] PCI: clean up dynamic pci id logic

The dynamic pci id logic has been bothering me for a while, and now that
I started to look into how to move some of this to the driver core, I
thought it was time to clean it all up.

It ends up making the code smaller, and easier to follow, and fixes a
few bugs at the same time (dynamic ids were not being matched
everywhere, and so could be missed on some call paths for new devices,
semaphore not needed to be grabbed when adding a new id and calling the
driver core, etc.)

I also renamed the function pci_match_device() to pci_match_id() as
that's what it really does.

Subject: [PATCH] gregkh-pci-pci-assign-unassigned-resources fix

It seems that X86 architectures in general need the setup-bus.o
not just those with HOTPLUG.  This avoids the following error on
X86_NUMAQ and x86_64:

    arch/i386/pci/built-in.o(.init.text+0x15a6): In function `pcibios_init':
    : undefined reference to `pci_assign_unassigned_resources'

Subject: [PATCH] amd74xx: support MCP55 device IDs

From: Rob Punkunus <rpunkunus@nvidia.com>

Rob Punkunus recently submitted a patch to enable support for MCP51/MCP55 in
the amd74xx driver. This patch was whitespace-corrupted and didn't apply to
2.6.12 since MCP51 support was merged in the 2.6.12-rc series.

Gentoo would like to support this hardware for our upcoming release media, so
I fixed the patch, and here it is :)

Subject: [PATCH] ARM: 2785/1: S3C24XX - serial calls request_irq() with IRQs
 disabled

Patch from Ben Dooks

The request_irq() function is called by s3c24xx uart driver with
the local IRQs disabled. The request_irq() function can allocate
memory via kmalloc(), and this may sleep causing a warning about
sleeping in an invalid context.

Subject: [PATCH] ARM: 2784/1: Fix the block cache flush operation range

Patch from Catalin Marinas

The range for the ARMv6 block cache operations is inclusive but the
kernel doesn't re-calculate the end address, causing a page fault when
used (this only happens with support for cache aliasing, otherwise the
blk_flush_kern_dcache_page() is not called). This patch subtracts
L1_CACHE_BYTES from the end address.

Subject: [SPARC64/COMPAT]: Add some compat ioctl for ppdev

The following patch adds some ioctls to include/linux/compat_ioctl.h
to allow using ppdev from the 32 bit user space on sparc64.

This patch also adds the PPDEV option in the sparc64 menu, near Parallel
printer support in the 'General machine setup' submenu.

All those ioctls seem to be compatible, since (correct me if I'm wrong)
they dont use the 'long' type. See include/linux/ppdev.h.

The application I used to test the new ioctls only used the following:
PPEXCL
PPCLAIM
PPNEGOT
PPGETMODES
PPRCONTROL
PPWCONTROL
PPDATADIR
PPWDATA
PPRDATA

But I beleive that the other ioctls will work fine.

From 088dd1f81b3577c17c4c4381696bf2105ea0e43a Mon Sep 17 00:00:00 2001
From: "David S. Miller" <davem@davemloft.net>

Subject: [SPARC64]: Add support for IRQ pre-handlers.

This allows a PCI controller to shim into IRQ delivery
so that DMA queues can be drained, if necessary.

If some bus specific code needs to run before an IRQ
handler is invoked, the bus driver simply needs to setup
the function pointer in bucket->irq_info->pre_handler and
the two args bucket->irq_info->pre_handler_arg[12].

The Schizo PCI driver is converted over to use a pre-handler
for the DMA write-sync processing it needs when a device
is behind a PCI->PCI bus deeper than the top-level APB
bridges.

While we're here, clean up all of the action allocation
and handling.  Now, we allocate the irqaction as part of
the bucket->irq_info area.  There is an array of 4 irqaction
(for PCI irq sharing) and a bitmask saying which entries
are active.

The bucket->irq_info is allocated at build_irq() time, not
at request_irq() time.  This simplifies request_irq() and
free_irq() tremendously.

The SMP dynamic IRQ retargetting code got removed in this
change too.  It was disabled for a few months now, and we
can resurrect it in the future if we want.

Subject: [SPARC64]: Do proper DMA IRQ syncing on Tomatillo

This was the main impetus behind adding the PCI IRQ shim.

In order to properly order DMA writes wrt. interrupts, you have to
write to a PCI controller register, then poll for that bit clearing.
There is one bit for each interrupt source, and setting this register
bit tells Tomatillo to drain all pending DMA from that device.

Furthermore, Tomatillo's with revision less than 4 require us to do a
block store due to some memory transaction ordering issues it has on
JBUS.

Subject: [NET]: Fix signedness issues in net/core/filter.c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is the code to load packet data into a register:

                        k = fentry->k;
                        if (k < 0) {
...
                        } else {
                                u32 _tmp, *p;
                                p = skb_header_pointer(skb, k, 4, &_tmp);
                                if (p != NULL) {
                                        A = ntohl(*p);
                                        continue;
                                }
                        }

skb_header_pointer checks if the requested data is within the
linear area:

        int hlen = skb_headlen(skb);

        if (offset + len <= hlen)
                return skb->data + offset;

When offset is within [INT_MAX-len+1..INT_MAX] the addition will
result in a negative number which is <= hlen.

I couldn't trigger a crash on my AMD64 with 2GB of memory, but a
coworker tried on his x86 machine and it crashed immediately.

This patch fixes the check in skb_header_pointer to handle large
positive offsets similar to skb_copy_bits. Invalid data can still
be accessed using negative offsets (also similar to skb_copy_bits),
anyone using negative offsets needs to verify them himself.

Thanks to Thomas Vögtle <thomas.voegtle@coreworks.de> for verifying the
problem by crashing his machine and providing me with an Oops.

Reduce local_df to a bit field and ip_summed to a 2 bits
field thus saving 13 bits. Move bit fields, packet type,
and protocol into the spare area between the priority
and the destructor. Saves 4 bytes on both, 32bit and
64bit architectures.

Subject: [PKT_SCHED]: Cleanup qdisc creation and alignment macros

Adds qdisc_alloc() to share code between qdisc_create()
and qdisc_create_dflt(). Hides the qdisc alignment behind
macros and makes use of them.

Subject: [PKT_SCHED]: Report rate estimator configuration errors during qdisc
 allocation

Current behaviour is to not report an error if a rate
estimator is created together with a qdisc and the
configuration of the rate estimator is bogus. This leads
to unexpected behaviour because the user is not notified.

New behaviour is to report the error and let the whole
qdisc creation operation fail so the user is able to fix
his mistake.

Subject: [IPV4]: Bug fix in rt_check_expire()

- rt_check_expire() fixes (an overflow occured if size of the hash
  was >= 65536)

reminder of the bugfix:

The rt_check_expire() has a serious problem on machines with large
route caches, and a standard HZ value of 1000.

With default values, ie ip_rt_gc_interval = 60*HZ = 60000 ;

the loop count :

     for (t = ip_rt_gc_interval << rt_hash_log; t >= 0;


overflows (t is a 31 bit value) as soon rt_hash_log is >= 16  (65536
slots in route cache hash table).

In this case, rt_check_expire() does nothing at all

Subject: [IPV4]: More broken memory allocation fixes for fib_trie

Below a patch to preallocate memory when doing resize of trie (inflate halve)
If preallocations fails it just skips the resize of this tnode for this time.

The oops we got when killing bgpd (with full routing) is now gone.
Patrick memory patch is also used.

Subject: [TCP]: Simplify SKB data portion allocation with NETIF_F_SG.

The ideal and most optimal layout for an SKB when doing
scatter-gather is to put all the headers at skb->data, and
all the user data in the page array.

This makes SKB splitting and combining extremely simple,
especially before a packet goes onto the wire the first
time.

So, when sk_stream_alloc_pskb() is given a zero size, make
sure there is no skb_tailroom().  This is achieved by applying
SKB_DATA_ALIGN() to the header length used here.

Next, make select_size() in TCP output segmentation use a
length of zero when NETIF_F_SG is true on the outgoing
interface.

Subject: [TCP]: Fix quick-ack decrementing with TSO.

On each packet output, we call tcp_dec_quickack_mode()
if the ACK flag is set.  It drops tp->ack.quick until
it hits zero, at which time we deflate the ATO value.

When doing TSO, we are emitting multiple packets with
ACK set, so we should decrement tp->ack.quick that many
segments.

Note that, unlike this case, tcp_enter_cwr() should not
take the tcp_skb_pcount(skb) into consideration.  That
function, one time, readjusts tp->snd_cwnd and moves
into TCP_CA_CWR state.

Subject: [TCP]: Move send test logic out of net/tcp.h

This just moves the code into tcp_output.c, no code logic changes are
made by this patch.

Using this as a baseline, we can begin to untangle the mess of
comparisons for the Nagle test et al.  We will also be able to reduce
all of the redundant computation that occurs when outputting data
packets.

It reimplements portions of tcp_snd_check(), so it
we move it to tcp_output.c we can consolidate it's
logic much easier in a later change.

Subject: [TCP]: Kill extra cwnd validate in __tcp_push_pending_frames().

The tcp_cwnd_validate() function should only be invoked
if we actually send some frames, yet __tcp_push_pending_frames()
will always invoke it.  tcp_write_xmit() does the call for us,
so the call here can simply be removed.

Also, tcp_write_xmit() can be marked static.

Subject: [TCP]: Fix redundant calculations of tcp_current_mss()

tcp_write_xmit() uses tcp_current_mss(), but some of it's callers,
namely __tcp_push_pending_frames(), already has this value available
already.

While we're here, fix the "cur_mss" argument to be "unsigned int"
instead of plain "unsigned".

Subject: [TCP]: Fix __tcp_push_pending_frames() 'nonagle' handling.

'nonagle' should be passed to the tcp_snd_test() function
as 'TCP_NAGLE_PUSH' if we are checking an SKB not at the
tail of the write_queue.  This is because Nagle does not
apply to such frames since we cannot possibly tack more
data onto them.

However, while doing this __tcp_push_pending_frames() makes
all of the packets in the write_queue use this modified
'nonagle' value.

Fix the bug and simplify this function by just calling
tcp_write_xmit() directly if sk_send_head is non-NULL.

As a result, we can now make tcp_data_snd_check() just call
tcp_push_pending_frames() instead of the specialized
__tcp_data_snd_check().

Subject: [TCP]: Break out tcp_snd_test() into it's constituent parts.

tcp_snd_test() does several different things, use inline
functions to express this more clearly.

1) It initializes the TSO count of SKB, if necessary.
2) It performs the Nagle test.
3) It makes sure the congestion window is adhered to.
4) It makes sure SKB fits into the send window.

This cleanup also sets things up so that things like the
available packets in the congestion window does not need
to be calculated multiple times by packet sending loops
such as tcp_write_xmit().

Subject: [TCP]: Eliminate redundant computations in tcp_write_xmit().

tcp_snd_test() is run for every packet output by a single
call to tcp_write_xmit(), but this is not necessary.

For one, the congestion window space needs to only be
calculated one time, then used throughout the duration
of the loop.

This cleanup also makes experimenting with different TSO
packetization schemes much easier.

Subject: [TCP]: Fix send-side cpu utiliziation regression.

Only put user data purely to pages when doing TSO.

The extra page allocations cause two problems:

1) Add the overhead of the page allocations themselves.
2) Make us do small user copies when we get to the end
   of the TCP socket cache page.

It is still beneficial to purely use pages for TSO,
so we will do it for that case.

Subject: [TCP]: Move to new TSO segmenting scheme.

Make TSO segment transmit size decisions at send time not earlier.

The basic scheme is that we try to build as large a TSO frame as
possible when pulling in the user data, but the size of the TSO frame
output to the card is determined at transmit time.

This is guided by tp->xmit_size_goal.  It is always set to a multiple
of MSS and tells sendmsg/sendpage how large an SKB to try and build.

Later, tcp_write_xmit() and tcp_push_one() chop up the packet if
necessary and conditions warrant.  These routines can also decide to
"defer" in order to wait for more ACKs to arrive and thus allow larger
TSO frames to be emitted.

A general observation is that TSO elongates the pipe, thus requiring a
larger congestion window and larger buffering especially at the sender
side.  Therefore, it is important that applications 1) get a large
enough socket send buffer (this is accomplished by our dynamic send
buffer expansion code) 2) do large enough writes.

Subject: [PKT_SCHED]: Blackhole queueing discipline

Useful in combination with classful qdiscs to drop or
temporary disable certain flows, e.g. one could block
specific ds flows with dsmark.

Unlike the noop qdisc it can be controlled by the user and
statistic accounting is done.

Subject: [TCP]: Never TSO defer under periods of congestion.

Congestion window recover after loss depends upon the fact
that if we have a full MSS sized frame at the head of the
send queue, we will send it.  TSO deferral can defeat the
ACK clocking necessary to exit cleanly from recovery.

+			LC-trie implementation notes.
+
+Node types
+----------
+leaf 
+	An end node with data. This has a copy of the relevant key, along
+	with 'hlist' with routing table entries sorted by prefix length.
+	See struct leaf and struct leaf_info.
+
+trie node or tnode
+	An internal node, holding an array of child (leaf or tnode) pointers,
+	indexed	through a subset of the key. See Level Compression.
+
+A few concepts explained
+------------------------
+Bits (tnode) 
+	The number of bits in the key segment used for indexing into the
+	child array - the "child index". See Level Compression.
+
+Pos (tnode)
+	The position (in the key) of the key segment used for indexing into
+	the child array. See Path Compression.
+
+Path Compression / skipped bits
+	Any given tnode is linked to from the child array of its parent, using
+	a segment of the key specified by the parent's "pos" and "bits" 
+	In certain cases, this tnode's own "pos" will not be immediately
+	adjacent to the parent (pos+bits), but there will be some bits
+	in the key skipped over because they represent a single path with no
+	deviations. These "skipped bits" constitute Path Compression.
+	Note that the search algorithm will simply skip over these bits when
+	searching, making it necessary to save the keys in the leaves to
+	verify that they actually do match the key we are searching for.
+
+Level Compression / child arrays
+	the trie is kept level balanced moving, under certain conditions, the
+	children of a full child (see "full_children") up one level, so that
+	instead of a pure binary tree, each internal node ("tnode") may
+	contain an arbitrarily large array of links to several children.
+	Conversely, a tnode with a mostly empty	child array (see empty_children)
+	may be "halved", having some of its children moved downwards one level,
+	in order to avoid ever-increasing child arrays.
+
+empty_children
+	the number of positions in the child array of a given tnode that are
+	NULL.
+
+full_children
+	the number of children of a given tnode that aren't path compressed.
+	(in other words, they aren't NULL or leaves and their "pos" is equal
+	to this	tnode's "pos"+"bits").
+
+	(The word "full" here is used more in the sense of "complete" than
+	as the opposite of "empty", which might be a tad confusing.)
+
+Comments
+---------
+
+We have tried to keep the structure of the code as close to fib_hash as 
+possible to allow verification and help up reviewing. 
+
+fib_find_node()
+	A good start for understanding this code. This function implements a
+	straightforward trie lookup.
+
+fib_insert_node()
+	Inserts a new leaf node in the trie. This is bit more complicated than
+	fib_find_node(). Inserting a new node means we might have to run the
+	level compression algorithm on part of the trie.
+
+trie_leaf_remove()
+	Looks up a key, deletes it and runs the level compression algorithm.
+
+trie_rebalance()
+	The key function for the dynamic trie after any change in the trie
+	it is run to optimize and reorganize. Tt will walk the trie upwards 
+	towards the root from a given tnode, doing a resize() at each step 
+	to implement level compression.
+
+resize()
+	Analyzes a tnode and optimizes the child array size by either inflating
+	or shrinking it repeatedly until it fullfills the criteria for optimal
+	level compression. This part follows the original paper pretty closely
+	and there may be some room for experimentation here.
+
+inflate()
+	Doubles the size of the child array within a tnode. Used by resize().
+
+halve()
+	Halves the size of the child array within a tnode - the inverse of
+	inflate(). Used by resize();
+
+fn_trie_insert(), fn_trie_delete(), fn_trie_select_default()
+	The route manipulation functions. Should conform pretty closely to the
+	corresponding functions in fib_hash.
+
+fn_trie_flush()
+	This walks the full trie (using nextleaf()) and searches for empty
+	leaves which have to be removed.
+
+fn_trie_dump()
+	Dumps the routing table ordered by prefix length. This is somewhat
+	slower than the corresponding fib_hash function, as we have to walk the
+	entire trie for each prefix length. In comparison, fib_hash is organized
+	as one "zone"/hash per prefix length.
+
+Locking
+-------
+
+fib_lock is used for an RW-lock in the same way that this is done in fib_hash.
+However, the functions are somewhat separated for other possible locking
+scenarios. It might conceivably be possible to run trie_rebalance via RCU
+to avoid read_lock in the fn_trie_lookup() function.
+
+Main lookup mechanism
+---------------------
+fn_trie_lookup() is the main lookup function.
+
+The lookup is in its simplest form just like fib_find_node(). We descend the
+trie, key segment by key segment, until we find a leaf. check_leaf() does
+the fib_semantic_match in the leaf's sorted prefix hlist.
+
+If we find a match, we are done.
+
+If we don't find a match, we enter prefix matching mode. The prefix length,
+starting out at the same as the key length, is reduced one step at a time,
+and we backtrack upwards through the trie trying to find a longest matching
+prefix. The goal is always to reach a leaf and get a positive result from the
+fib_semantic_match mechanism.
+
+Inside each tnode, the search for longest matching prefix consists of searching
+through the child array, chopping off (zeroing) the least significant "1" of
+the child index until we find a match or the child index consists of nothing but
+zeros.
+
+At this point we backtrack (t->stats.backtrack++) up the trie, continuing to
+chop off part of the key in order to find the longest matching prefix.
+
+At this point we will repeatedly descend subtries to look for a match, and there
+are some optimizations available that can provide us with "shortcuts" to avoid
+descending into dead ends. Look for "HL_OPTIMIZE" sections in the code.
+
+To alleviate any doubts about the correctness of the route selection process,
+a new netlink operation has been added. Look for NETLINK_FIB_LOOKUP, which
+gives userland access to fib_lookup().

Subject: [PATCH] ppc32: add Freescale MPC885ADS board support

This patch adds the Freescale MPC86xADS board support.  The supported
devices are SMC UART and 10Mbit ethernet on SCC1.

The manual for the board says that it "is compatible with the MPC8xxFADS
for software point of view".  That's why this patch extends FADS instead of
introducing a new platform.

FEC is not supported as the "combined FCC/FEC ethernet driver" driver by
Pantelis Antoniou should replace the current FEC driver.

Subject: [PATCH] ppc32: stop misusing NTP's time_offset value

As part of my timeofday rework, I've been looking at the NTP code and I
noticed that the PPC architecture is apparently misusing the NTP's
time_offset (it is a terrible name!) value as some form of timezone offset.

This could cause problems when time_offset changed by the NTP code.  This
patch changes the PPC code so it uses a more clear local variable:
timezone_offset.

Subject: [PATCH] ppc32: explicitly disable 440GP IRQ compatibility mode in
 440GX setup

Add explicit disabling of 440GP IRQ compatibility mode when configuring
440GX interrupt controller.  This helps when board firmware for some reason
uses this compatibility mode and leaves it enabled.  It breaks 440GX
interrupt code because it assumes native 440GX IRQ mode.  People seems to
be continuously bitten by this.

Subject: [PATCH] kprobes: fix namespace problem and sparc64 build

The following renames arch_init, a kprobes function for performing any
architecture specific initialization, to arch_init_kprobes in order to
cleanup the namespace.

Also, this patch adds arch_init_kprobes to sparc64 to fix the sparc64 kprobes
build from the last return probe patch.

Use an rbtree instead of a simple linked list. We were wasting
an amazing amount of time in jffs2_add_tn_to_list().

Subject: [PATCH] Fix broken kmalloc_node in rc1/rc2

This patch used to be in Andrew's tree before the NUMA slab allocator went
in. Either this patch or the NUMA slab allocator is needed in order for
kmalloc_node to work correctly.

pcibus_to_node may be used to generate the node information passed to
kmalloc_node. pcibus_to_node returns -1 if it was not able to determine
on which node a pcibus is located. For that case kmalloc_node must
work like kmalloc.

From: Jeff Mahoney <jeffm@suse.com>
Date: Wed, 6 Jul 2005 15:44:41 -0400
Subject: [PATCH] openfirmware: generate device table for userspace

This converts the usage of struct of_match to struct of_device_id,
similar to pci_device_id.  This allows a device table to be generated,
which can be parsed by depmod(8) to generate a map file for module
loading.

In order for hotplug to work with macio devices, patches to
module-init-tools and hotplug must be applied.  Those patches are
available at:

 ftp://ftp.suse.com/pub/people/jeffm/linux/macio-hotplug/

Subject: [PATCH] openfirmware: add sysfs nodes for open firmware devices

This adds sysfs nodes that the hotplug userspace can use to load the
appropriate modules.

In order for hotplug to work with macio devices, patches to
module-init-tools and hotplug must be applied.  Those patches are
available at:

 ftp://ftp.suse.com/pub/people/jeffm/linux/macio-hotplug/

Changes: The previous versions were built on 2.6.12. 2.6.13-rcX introduced
         a device_attribute parameter to the show functions. Since that
         parameter was treated as the output buffer, memory corruption would
         result, causing Oopsen very quickly.

Subject: [PATCH] openfirmware: implement hotplug for macio devices

This adds the hotplug routine for generating hotplug events when devices
are seen on the macio bus.  It uses the attributed created by the sysfs
nodes to generate the hotplug environment vars for userspace.

Since the characters allowed inside the 'compatible' field are NUL
terminated, they are exported as individual OF_COMPATIBLE_# variables,
with OF_COMPATIBLE_N maintaining a count of how many there are.

In order for hotplug to work with macio devices, patches to
module-init-tools and hotplug must be applied.  Those patches are
available at:

Subject: [CRYPTO] Add plumbing for multi-block operations

The VIA Padlock device is able to perform much better when multiple
blocks are fed to it at once.  As this device offers an exceptional
throughput rate it is worthwhile to optimise the infrastructure
specifically for it.

We shift the existing page-sized fast path down to the CBC/ECB functions.
We can then replace the CBC/ECB functions with functions provided by the
underlying algorithm that performs the multi-block operations.

As a side-effect this improves the performance of large cipher operations
for all existing algorithm implementations.  I've measured the gain to be
around 5% for 3DES and 15% for AES.

Subject: [CRYPTO] Add support for low-level multi-block operations

This patch adds hooks for cipher algorithms to implement multi-block
ECB/CBC operations directly.  This is expected to provide significant
performance boots to the VIA Padlock.

It could also be used for improving software implementations such as
AES where operating on multiple blocks at a time may enable certain
optimisations.

Subject: [CRYPTO] Add alignmask for low-level cipher implementations

The VIA Padlock device requires the input and output buffers to
be aligned on 16-byte boundaries.  This patch adds the alignmask
attribute for low-level cipher implementations to indicate their
alignment requirements.

The mid-level crypt() function will copy the input/output buffers
if they are not aligned correctly before they are passed to the
low-level implementation.

Strictly speaking, some of the software implementations require
the buffers to be aligned on 4-byte boundaries as they do 32-bit
loads.  However, it is not clear whether it is better to copy
the buffers or pay the penalty for unaligned loads/stores.

Subject: [PADLOCK] Move fast path work into aes_set_key and upper layer

Most of the work done aes_padlock can be done in aes_set_key.  This
means that we only have to do it once when the key changes rather
than every time we perform an encryption or decryption.

This patch also sets cra_alignmask to let the upper layer ensure
that the buffers fed to us are aligned correctly.

Subject: [CRYPTO] Ensure cit_iv is aligned correctly

This patch ensures that cit_iv is aligned according to cra_alignmask
by allocating it as part of the tfm structure.  As a side effect the
crypto layer will also guarantee that the tfm ctx area has enough space
to be aligned by cra_alignmask.  This allows us to remove the extra
space reservation from the Padlock driver.

Subject: [CRYPTO] Handle unaligned iv from encrypt_iv/decrypt_iv

Even though cit_iv is now always aligned, the user can still supply an
unaligned iv through crypto_cipher_encrypt_iv/crypto_cipher_decrypt_iv.
This patch will check the alignment of the user-supplied iv and copy
it if necessary.

Subject: [CRYPTO] Update IV correctly for Padlock CBC encryption

When the Padlock does CBC encryption, the memory pointed to by EAX is
not updated at all.  Instead, it updates the value of EAX by pointing
it to the last block in the output.  Therefore to maintain the correct
semantics we need to copy the IV.

Subject: [CRYPTO] Add null short circuit to crypto_free_tfm

As far as I'm aware there's a general concensus that functions that are
responsible for freeing resources should be able to cope with being passed
a NULL pointer. This makes sense as it removes the need for all callers to
check for NULL, thus elliminating the bugs that happen when some forget
(safer to just check centrally in the freeing function) and it also makes
for smaller code all over due to the lack of all those NULL checks.
This patch makes it safe to pass the crypto_free_tfm() function a NULL
pointer. Once this patch is applied we can start removing the NULL checks
from the callers.

Subject: [CRYPTO] Add x86_64 asm AES

Implementation:
===============
The encrypt/decrypt code is based on an x86 implementation I did a while
ago which I never published. This unpublished implementation does
include an assembler based key schedule and precomputed tables. For
simplicity and best acceptance, however, I took Gladman's in-kernel code
for table generation and key schedule for the kernel port of my
assembler code and modified this code to produce the key schedule as
required by my assembler implementation. File locations and Kconfig are
kept similar to the i586 AES assembler implementation.
It may seem a little bit strange to use 32 bit I/O and registers in the
assembler implementation but this gives the best code size. My
implementation takes one instruction more per round compared to
Gladman's x86 assembler but it doesn't require any stack for local
variables or saved registers and it is less serialized than Gladman's
code.
Note that all comparisons to Gladman's code were done after my code was
implemented. I did only use FIPS PUB 197 for the implementation so my
implementation is independent work.
If anybody has a better assembler solution for x86_64 I'll be pleased to
have my code replaced with the better solution.

Testing:
========
The implementation passes the in-kernel crypto testing module and I'm
running it without any problems on my laptop where it is mainly used for
dm-crypt.

Microbenchmark:
===============
The microbenchmark was done in userspace with similar compile flags as
used during kernel compile.
Encrypt/decrypt is about 35% faster than the generic C implementation.
As the generic C as well as my assembler implementation are both table
I don't really expect that there is much room for further
improvements though I'll be glad to be corrected here.
The key schedule is about 5% slower than the generic C implementation.
This is due to the fact that some more work has to be done in the key
schedule routine to fit the schedule to the assembler implementation.

Code Size:
==========
Encrypt and decrypt are together about 2.1 Kbytes smaller than the
generic C implementation which is important with regard to L1 cache
usage. The key schedule routine is about 100 bytes larger than the
generic C implementation.

Data Size:
==========
There's no difference in data size requirements between the assembler
implementation and the generic C implementation.

License:
========
Gladmans's code is dual BSD/GPL whereas my assembler code is GPLv2 only
(I'm  not going to change the license for my code). So I had to change
the module license for the x86_64 aes module from 'Dual BSD/GPL' to
'GPL' to reflect the most restrictive license within the module.

Subject: [CRYPTO] Add faster DES code from Dag Arne Osvik

I've made a new implementation of DES to replace the old one in the kernel.
It provides faster encryption on all tested processors apart from the original
Pentium, and key setup is many times faster.

From cb4cb2cb9b0b14bdf2fc7125e099ed7e818cea42 Mon Sep 17 00:00:00 2001
From: Prarit Bhargava <prarit@sgi.com>
Date: Wed, 6 Jul 2005 14:59:44 -0700
Subject: [IA64] hotplug/ia64: SN Hotplug Driver: SN IRQ Fixes

This patch  fixes the SN IRQ code such that cpu affinity and
Hotplug can modify IRQ values.  The sn_irq_info structures are now locked
using a RCU lock mechanism to avoid lock contention in the lost interrupt
WAR code.

Subject: [PATCH] ARM: 2789/1: Enable access to both CP10 and CP11 on ARMv6

Patch from Catalin Marinas

The VFP instructions trigger undefined exceptions because the access to
CP11 is disabled (only CP10 is currently enabled by the kernel). The patch
fixes this problem.

Subject: [PATCH] ARM: 2792/1: IXP4xx iomap API implementation

Patch from Deepak Saxena

This patch implements the iomap API for Intel IXP4xx NPU systems.
We need to implement our own version of the API functions b/c of the
PCI hostbridge does not provide the capability to map PCI I/O space
into the CPU's physical memory space. In addition, if a system has
more than 64M of PCI memory mapped BARs, PCI memory must also be
accessed indirectly.  This patch changes the assignment of PCI I/O
resources to fall into to 0x0000:0xffff range so that we can trap
I/O areas in our ioread/iowrite macros.

- * PIC AS DEVICE ZERO
- * ------------------
- *
- * PIC handles PCI/X busses.  PCI/X requires that the 'bridge' (i.e. PIC)
- * be designated as 'device 0'.   That is a departure from earlier SGI
- * PCI bridges.  Because of that we use config space 1 to access the
- * config space of the first actual PCI device on the bus. 
- * Here's what the PIC manual says:
- *
- *     The current PCI-X bus specification now defines that the parent
- *     hosts bus bridge (PIC for example) must be device 0 on bus 0. PIC
- *     reduced the total number of devices from 8 to 4 and removed the
- *     device registers and windows, now only supporting devices 0,1,2, and
- *     3. PIC did leave all 8 configuration space windows. The reason was
- *     there was nothing to gain by removing them. Here in lies the problem.
- *     The device numbering we do using 0 through 3 is unrelated to the device
- *     numbering which PCI-X requires in configuration space. In the past we
- *     correlated Configs pace and our device space 0 <-> 0, 1 <-> 1, etc.
- *     PCI-X requires we start a 1, not 0 and currently the PX brick
- *     does associate our:
- * 
- *         device 0 with configuration space window 1,
- *         device 1 with configuration space window 2, 
- *         device 2 with configuration space window 3,
- *         device 3 with configuration space window 4.
- *
- * The net effect is that all config space access are off-by-one with 
- * relation to other per-slot accesses on the PIC.   
- * Here is a table that shows some of that:
- *
- *                               Internal Slot#
- *           |
- *           |     0         1        2         3
- * ----------|---------------------------------------
- * config    |  0x21000   0x22000  0x23000   0x24000
- *           |
- * even rrb  |  0[0]      n/a      1[0]      n/a	[] == implied even/odd
- *           |
- * odd rrb   |  n/a       0[1]     n/a       1[1]
- *           |
- * int dev   |  00       01        10        11
- *           |
- * ext slot# |  1        2         3         4

+ * PIC AS DEVICE ZERO
+ * ------------------
+ *
+ * PIC handles PCI/X busses.  PCI/X requires that the 'bridge' (i.e. PIC)
+ * be designated as 'device 0'.   That is a departure from earlier SGI
+ * PCI bridges.  Because of that we use config space 1 to access the
+ * config space of the first actual PCI device on the bus.
+ * Here's what the PIC manual says:
+ *
+ *     The current PCI-X bus specification now defines that the parent
+ *     hosts bus bridge (PIC for example) must be device 0 on bus 0. PIC
+ *     reduced the total number of devices from 8 to 4 and removed the
+ *     device registers and windows, now only supporting devices 0,1,2, and
+ *     3. PIC did leave all 8 configuration space windows. The reason was
+ *     there was nothing to gain by removing them. Here in lies the problem.
+ *     The device numbering we do using 0 through 3 is unrelated to the device
+ *     numbering which PCI-X requires in configuration space. In the past we
+ *     correlated Configs pace and our device space 0 <-> 0, 1 <-> 1, etc.
+ *     PCI-X requires we start a 1, not 0 and currently the PX brick
+ *     does associate our:
+ *
+ *         device 0 with configuration space window 1,
+ *         device 1 with configuration space window 2,
+ *         device 2 with configuration space window 3,
+ *         device 3 with configuration space window 4.
+ *
+ * The net effect is that all config space access are off-by-one with
+ * relation to other per-slot accesses on the PIC.
+ * Here is a table that shows some of that:
+ *
+ *                               Internal Slot#
+ *           |

Subject: [IA64] hotplug/ia64: SN Hotplug Driver - new SN PROM version code

This patch is a rewrite of the code to check the PROM version.  The current
code has some deficiences in the way PROM comparisons were made.  The minimum
value of PROM that will boot has also been changed to 4.04.

This patch is the SGI hotplug driver and additional changes required for
the driver.  These modifications include changes to the SN io_init.c code
for memory management, the inclusion of new SAL calls to enable and disable
PCI slots, and a hotplug-style driver.

Subject: [IA64] hotplug/ia64: SN Hotplug Driver - PREEMPT/pcibus_info fix

This patch fixes an issue with the PROM and a kernel running with
CONFIG_PREEMPT enabled.  When CONFIG_PREEMPT is enabled, the size of a
spinlock_t changes -- resulting in the PROM writing to an incorrect location.

Subject: [IA64] memory-less-nodes repost

I reworked how nodes with only CPUs are treated.  The patch below seems
simpler to me and has eliminated the complicated routine
reassign_cpu_only_nodes.  There isn't any longer the requirement
to modify ACPI NUMA information which was in large part the
complexity introduced in reassign_cpu_only_nodes.

This patch will produce a different number of nodes. For example,
reassign_cpu_only_nodes would reduce two CPUonly nodes and one memory node
configuration to one memory+CPUs node configuration.  This patch
doesn't change the number of nodes which means the user will see three.  Two
nodes without memory and one node with all the memory.

While doing this patch, I noticed that early_nr_phys_cpus_node isn't serving
any useful purpose.  It is called once in find_pernode_space but the value
isn't used to computer pernode space.

Subject: [PATCH] yet another fix for setup-bus.c/x86 merge

There is a slight disagreement between setup-bus.c code and traditional
x86 PCI setup wrt which recourses are invalid vs resources that are free
for further allocations.

In particular, in the setup-bus.c, if we failed to allocate some resource,
we nullify "start" and "flags" fields, but *not* the "end" one.

But x86 pcibios_enable_resources() does the following check:

	if (!r->start && r->end) {
		printk(KERN_ERR "PCI: Device %s not available because of resource collisions\n", pci_name(dev));
		return -EINVAL;

which means that the device owning the offending resource cannot be
enabled.

In particular, this breaks cardbus behind the normal decode p2p bridge -
the cardbus code from setup-bus.c requests rather large IO and MEM
windows, and if it fails, the socket is completely unavailable.  Which
is wrong, as the yenta code is capable to allocate smaller windows.

Subject: [IA64] fix generic/up builds

Jesse Barnes provided the original version of this patch months ago, but
other changes kept conflicting with it, so it got deferred.  Greg Edwards
dug it out of obscurity just over a week ago, and almost immediately
another conflicting patch appeared (Bob Picco's memory-less nodes).

I've resolved the conflicts and got it running again.  CONFIG_SGI_TIOCX
is set to "y" in defconfig, which causes a Tiger to not boot (oops in
tiocx_init).  But that can be resolved later ... get this in now before it
gets stale again.

Subject: [PATCH] export generic_drop_inode() to modules

OCFS2 wants to mark an inode which has been orphaned by another node so
that during final iput it takes the correct path through the VFS and can
pass through the OCFS2 delete_inode callback.  Since i_nlink can get out of
date with other nodes, the best way I see to accomplish this is by clearing
i_nlink on those inodes at drop_inode time.  Other than this small amount
of work, nothing different needs to happen, so I think it would be cleanest
to be able to just call generic_drop_inode at the end of the OCFS2
drop_inode callback.

Subject: [PATCH] mm: quieten OOM killer noise

We now print statistics when invoking the OOM killer, however this
information is not rate limited and you can get into situations where the
console is continually spammed.

For example, when a task is exiting the OOM killer will simply return
(waiting for that task to exit and clear up memory).  If the VM continually
calls back into the OOM killer we get thousands of copies of show_mem() on
the console.

Use printk_ratelimit() to quieten it.

This is usefull when one only wants to compile a single module and thus do

Subject: [PATCH] ppc64: Turn runlatch on in exception entry

Enable the runlatch at the start of each exception.  Unfortunately we are out
of space in the 0x300 handler, so I added it a bit later.

The SPR write is fairly expensive, perhaps we should cache the runlatch state
in the paca and avoid the write when possible.

We don't need to turn the runlatch off, we do that in the idle loop.  Better
to take the hit in the idle loop than for each exception exit.

Subject: [PATCH] hvc_console: Rearrange code

Milton Miller has done a lot of work to clean up our hvc_console code.

One of the important things the following patch series does is separate the
VIO layer from the hvc_console code.  With the VIO specific code removed any
ppc64 platform, or even any architecture, can use hvc_console as a generic
polling console.  You simply have to supply a get_chars and put_chars method
and hvc_console does the rest of the work.  You can even use it for an
interrupt driven console.

This patch:

Rearrange the code in drivers/char/hvc_console.c to make future patches
smaller.  No actual code changes, just ordering of the functions in the file.

Subject: [PATCH] hvc_console: Match vio and console devices using vterm
 numbers

Use the vterm numbers to match the vio devices being probed with the indices
already allocated via the console initcall function hvc_find_vtys.

The old code required hvc_find_vtys to "guess" the matching devices the vio
subsystem would find and its probe order.

Subject: [PATCH] hvc_console: Separate hvc_console and vio code

Separate the console setup routines of the hvc_console and the vio layer.

Remove the call to find_init_vty from hvc_console.c.

Fail the setup routine if the console doesn't exist, but register the console
again when the specified channel is instantiated.  This scheme maintains the
print buffer semantics while eliminating callout and call back for the console
code.

Subject: [PATCH] hvc_console: Register ops when setting up hvc_console

When registering the hvc console port, register a list of ops (read and write)
to go with it, instead of calling fixed function names.

This allows different ports to encode the data differently.

Subject: [PATCH] ppc64: iSeries idle fixups

- remove min/max yield time, we dont use the values anywhere
- separate shared and dedicated idle loops
- check need_resched again with irqs off to avoid sleeping with pending work
- continually set runlatch off in idle loop, this means we dont need to
  turn the runlatch off on exception exit and suffer that associated
  cost for all exceptions. (A future patch will turn the runlatch on at
  exception entry)

Subject: [PATCH] ppc64: Be consistent about printing which idle loop we're
 using

Not sure if we really need this, but it was handy to know which iSeries loop I
was testing.

Be consistent about printing which idle loop we're using, with this patch we
cover all cases.

Subject: [PATCH] ppc64: silence perfmon exception warnings

We dont need to use the PERFMON exception on POWER5, in fact the firmware
returns an error.  Due to this just remove the warning.

Also now that we have proper runlatch support we can remove the bootup
hack.

Subject: [PATCH] MTRR suspend/resume cleanup

There has been some discuss about solving the SMP MTRR suspend/resume
breakage, but I didn't find a patch for it.  This is an intent for it.  The
basic idea is moving mtrr initializing into cpu_identify for all APs (so it
works for cpu hotplug).  For BP, restore_processor_state is responsible for
restoring MTRR.

Subject: [PATCH] Clean up numa defines in mmzone.h

The recent cleanups to asm-i386/mmzone.h were suboptimal nesting an ifdef of
the same symbol.  This patch removes some of the ifdef'ery to make things more
readable again.

Subject: [PATCH] Fix up non-NUMA breakage in mmzone.h

If CONFIG_NUMA isn't set, we use the define in <linux/mmzone.h> for
early_pfn_to_nid (which defines it to 0).

Because of this, the prototype needs to move inside the CONFIG_NUMA too, or
anal gcc's get really confused.

Subject: [PATCH] uml: skas0 - separate kernel address space on stock hosts

UML has had two modes of operation - an insecure, slow mode (tt mode) in
which the kernel is mapped into every process address space which requires
no host kernel modifications, and a secure, faster mode (skas mode) in
which the UML kernel is in a separate host address space, which requires a
patch to the host kernel.

This patch implements something very close to skas mode for hosts which
don't support skas - I'm calling this skas0.  It provides the security of
the skas host patch, and some of the performance gains.

The two main things that are provided by the skas patch, /proc/mm and
PTRACE_FAULTINFO, are implemented in a way that require no host patch.

For the remote address space changing stuff (mmap, munmap, and mprotect),
we set aside two pages in the process above its stack, one of which
contains a little bit of code which can call mmap et al.

To update the address space, the system call information (system call
number and arguments) are written to the stub page above the code.  The
%esp is set to the beginning of the data, the %eip is set the the start of
the stub, and it repeatedly pops the information into its registers and
makes the system call until it sees a system call number of zero.  This is
to amortize the cost of the context switch across multiple address space
updates.

When the updates are done, it SIGSTOPs itself, and the kernel process
continues what it was doing.

For a PTRACE_FAULTINFO replacement, we set up a SIGSEGV handler in the
child, and let it handle segfaults rather than nullifying them.  The
handler is in the same page as the mmap stub.  The second page is used as
the stack.  The handler reads cr2 and err from the sigcontext, sticks them
at the base of the stack in a faultinfo struct, and SIGSTOPs itself.  The
kernel then reads the faultinfo and handles the fault.

A complication on x86_64 is that this involves resetting the registers to
the segfault values when the process is inside the kill system call.  This
breaks on x86_64 because %rcx will contain %rip because you tell SYSRET
where to return to by putting the value in %rcx.  So, this corrupts $rcx on
return from the segfault.  To work around this, I added an
arch_finish_segv, which on x86 does nothing, but which on x86_64 ptraces
the child back through the sigreturn.  This causes %rcx to be restored by
sigreturn and avoids the corruption.  Ultimately, I think I will replace
this with the trick of having it send itself a blocked signal which will be
unblocked by the sigreturn.  This will allow it to be stopped just after
the sigreturn, and PTRACE_SYSCALLed without all the back-and-forth of
PTRACE_SYSCALLing it through sigreturn.

This runs on a stock host, so theoretically (and hopefully), tt mode isn't
needed any more.  We need to make sure that this is better in every way
than tt mode, though.  I'm concerned about the speed of address space
updates and page fault handling, since they involve extra round-trips to
the child.  We can amortize the round-trip cost for large address space
updates by writing all of the operations to the data page and having the
child execute them all at the same time.  This will help fork and exec, but
not page faults, since they involve only one page.

I can't think of any way to help page faults, except to add something like
PTRACE_FAULTINFO to the host.  There is PTRACE_SIGINFO, but UML doesn't use
siginfo for SIGSEGV (or anything else) because there isn't enough
information in the siginfo struct to handle page faults (the faulting
operation type is missing).  Adding that would make PTRACE_SIGINFO a usable
equivalent to PTRACE_FAULTINFO.

As for the code itself:

- The system call stub is in arch/um/kernel/sys-$(SUBARCH)/stub.S.  It is
  put in its own section of the binary along with stub_segv_handler in
  arch/um/kernel/skas/process.c.  This is manipulated with run_syscall_stub
  in arch/um/kernel/skas/mem_user.c.  syscall_stub will execute any system
  call at all, but it's only used for mmap, munmap, and mprotect.

- The x86_64 stub calls sigreturn by hand rather than allowing the normal
  sigreturn to happen, because the normal sigreturn is a SA_RESTORER in
  UML's address space provided by libc.  Needless to say, this is not
  available in the child's address space.  Also, it does a couple of odd
  pops before that which restore the stack to the state it was in at the
  time the signal handler was called.

- There is a new field in the arch mmu_context, which is now a union.
  This is the pid to be manipulated rather than the /proc/mm file
  descriptor.  Code which deals with this now checks proc_mm to see whether
  it should use the usual skas code or the new code.

- userspace_tramp is now used to create a new host process for every UML
  process, rather than one per UML processor.  It checks proc_mm and
  ptrace_faultinfo to decide whether to map in the pages above its stack.

- start_userspace now makes CLONE_VM conditional on proc_mm since we need
  separate address spaces now.

- switch_mm_skas now just sets userspace_pid[0] to the new pid rather
  than PTRACE_SWITCH_MM.  There is an addition to userspace which updates
  its idea of the pid being manipulated each time around the loop.  This is
  important on exec, when the pid will change underneath userspace().

- The stub page has a pte, but it can't be mapped in using tlb_flush
  because it is part of tlb_flush.  This is why it's required for it to be
  mapped in by userspace_tramp.

Other random things:

- The stub section in uml.lds.S is page aligned.  This page is written
  out to the backing vm file in setup_physmem because it is mapped from
  there into user processes.

- There's some confusion with TASK_SIZE now that there are a couple of
  extra pages that the process can't use.  TASK_SIZE is considered by the
  elf code to be the usable process memory, which is reasonable, so it is
  decreased by two pages.  This confuses the definition of
  USER_PGDS_IN_LAST_PML4, making it too small because of the rounding down
  of the uneven division.  So we round it to the nearest PGDIR_SIZE rather
  than the lower one.

- I added a missing PT_SYSCALL_ARG6_OFFSET macro.

- um_mmu.h was made into a userspace-usable file.

- proc_mm and ptrace_faultinfo are globals which say whether the host
  supports these features.

- There is a bad interaction between the mm.nr_ptes check at the end of
  exit_mmap, stack randomization, and skas0.  exit_mmap will stop freeing
  pages at the PGDIR_SIZE boundary after the last vma.  If the stack isn't
  on the last page table page, the last pte page won't be freed, as it
  should be since the stub ptes are there, and exit_mmap will BUG because
  there is an unfreed page.  To get around this, TASK_SIZE is set to the
  next lowest PGDIR_SIZE boundary and mm->nr_ptes is decremented after the
  calls to init_stub_pte.  This ensures that we know the process stack (and
  all other process mappings) will be below the top page table page, and
  thus we know that mm->nr_ptes will be one too many, and can be
  decremented.

Things that need fixing:

- We may need better assurrences that the stub code is PIC.

- The stub pte is set up in init_new_context_skas.

- alloc_pgdir is probably the right place.

From 9786a8f3cbc61f990266e23ffdb338ee3118b03d Mon Sep 17 00:00:00 2001
From: Bodo Stroesser <bstroesser@fujitsu-siemens.com>
Date: Thu, 7 Jul 2005 17:56:50 -0700
Subject: [PATCH] uml: Proper clone support for skas0

This patch implements the clone-stub mechanism, which allows skas0 to run
with proc_mm==0, even if the clib in UML uses modify_ldt.

Note: There is a bug in skas3.v7 host patch, that avoids UML-skas from
running properly on a SMP-box.  In full skas3, I never really saw problems,
but in skas0 they showed up.

More commentary by jdike - What this patch does is makes sure that the host
parent of each new host process matches the UML parent of the corresponding
UML process.  This ensures that any changed LDTs are inherited.  This is
done by having clone actually called by the UML process from its stub,
rather than by the kernel.  We have special syscall stubs that are loaded
onto the stub code page because that code must be completely
self-contained.  These stubs are given C interfaces, and used like normal C
functions, but there are subtleties.  Principally, we have to be careful
about stack variables in stub_clone_handler after the clone.  The code is
written so that there aren't any - everything boils down to a fixed
address.  If there were any locals, references to them after the clone
would be wrong because the stack just changed.

Subject: [PATCH] uml: restore hppfs support

Some time ago a trivial patch broke HPPFS (one var became a pointer, not
all uses were updated).  It wasn't fixed at that time because not very
used, now it's been requested so I've fixed this, and it has been tested
positively (at least partially).

Subject: [PATCH] uml: remove winch sem

Replace a semaphore (winch_handler_sem) used in atomic code with a
spinlock, and reduces as needed the amount of protected code to the bare
minimum (for instance no kmalloc calls are needed).

This fixes the last problems with spinlocking (in UP mode with DEBUG
options); the semaphore, taken inside spinlocks, caused a "spin_lock was
already locked" warning, without this patch.

Subject: [PATCH] xtensa: remove old syscalls

xtensa is now in -rc1, with the obsolete syscalls still in there, so I
guess this about the last chance to correct the ABI.  Applying the patch
obviously breaks all sorts of user space binaries and probably also
requires the appropriate changes to be made to libc.

On the other hand, if a decision is made to keep the broken interface, it
should at least be a conscious one instead of an oversight.

Subject: [PATCH] tty output lossage fix

The patch fixes a few corner cases around tty line editing with
very long input lines:

- n_tty_receive_char(): don't simply drop eol characters,
  otherwise canon_data isn't increased and the reader isn't woken
  up.

- n_tty_receive_room(): If there is no newline pending and the
  edit buffer is full, allow only a single character to be written
  (until eol is found and the line is flushed), so characters from
  the next line aren't dropped.

- write_chan(): if an incomplete line was written, continue
  writing until write() returns 0, otherwise it might not write
  the eol character to flush the line and the writer goes to sleep
  without ever being woken up.

BTW the core problem is that part of this should be handled in the
receive_buf path, but for this it has to return the number of
written characters, as the amount of written characters may not be
the same as the amount of characters going into the write buffer,
so the receive_room() usage in pty_write() is not really reliable.

Alan said:

The problem looks valid. The behaviour of 'traditional unix' appears to
be the following

	If you exceed the line limit then beep and drop the character
	Always allow EOL to complete a canonical line input
	Always do signal/control processing if enabled

Use a bit spin lock in the first buffer of the page to synchronise asynch
IO buffer completions, instead of the global page_uptodate_lock, which is
showing some scalabilty problems.

Subject: [PATCH] mostly_read data section

Add a new section called ".data.read_mostly" for data items that are read
frequently and rarely written to like cpumaps etc.

If these maps are placed in the .data section then these frequenly read
items may end up in cachelines with data is is frequently updated.  In that
case all processors in an SMP system must needlessly reload the cachelines
again and again containing elements of those frequently used variables.

The ability to share these cachelines will allow each cpu in an SMP system
to keep local copies of those shared cachelines thereby optimizing
performance.

Subject: [PATCH] ext3 xattr: Don't write to the in-inode xattr space of
 reserved inodes

We are not using the in-inode space for xattrs in reserved inodes because
mkfs.ext3 doesn't initialize it properly.  For those inodes, we set
i_extra_isize to 0.  Make sure that we also don't overwrite the
i_extra_isize field when writing out the inode in that case.  This is for
cleanliness only, and doesn't fix an actual bug.

Subject: [PATCH] IB uverbs: core API extensions

First of a series of patches which add support for direct userspace access to
InfiniBand hardware -- so-called "userspace verbs." I believe these patches
are ready to merge, but a final review would be useful.

These patches should incorporate all of the feedback from the discussion when
I posted an earlier version back in April (see
http://lkml.org/lkml/2005/4/4/267 for the start of the thread).  In
particular, memory pinned for use by userspace is accounted for in
current->mm->vm_locked and requests to pin memory are checked against
RLIMIT_MEMLOCK.

This patch:

Modify the ib_verbs.h header file with changes required for InfiniBand
userspace verbs support.  We add a few structures to keep track of userspace
context, and extend the driver API so that low-level drivers know when they're
creating resources that will be used from userspace.

Subject: [PATCH] IB uverbs: update kernel midlayer for new API

Update kernel InfiniBand midlayer to compile against the updated API for
low-level drivers.  This just amounts to passing NULL for all
userspace-related parameters, and setting userspace-related structure members
to NULL.

Subject: [PATCH] IB uverbs: add mthca mmap support

Add support for mmap() method to mthca, so that userspace can get access to
doorbell registers.  This allows userspace to get direct access to the HCA for
data path operations.

Each userspace context gets its own copy of the doorbell registers and is only
allowed to use resources that the kernel has given it access to.  In other
words, this is safe.

+USERSPACE VERBS ACCESS
+
+  The ib_uverbs module, built by enabling CONFIG_INFINIBAND_USER_VERBS,
+  enables direct userspace access to IB hardware via "verbs," as
+  described in chapter 11 of the InfiniBand Architecture Specification.
+
+  To use the verbs, the libibverbs library, available from
+  <http://openib.org/>, is required.  libibverbs contains a
+  device-independent API for using the ib_uverbs interface.
+  libibverbs also requires appropriate device-dependent kernel and
+  userspace driver for your InfiniBand hardware.  For example, to use
+  a Mellanox HCA, you will need the ib_mthca kernel module and the
+  libmthca userspace driver be installed.
+
+User-kernel communication
+
+  Userspace communicates with the kernel for slow path, resource
+  management operations via the /dev/infiniband/uverbsN character
+  devices.  Fast path operations are typically performed by writing
+  directly to hardware registers mmap()ed into userspace, with no
+  system call or context switch into the kernel.
+
+  Commands are sent to the kernel via write()s on these device files.
+  The ABI is defined in drivers/infiniband/include/ib_user_verbs.h.
+  The structs for commands that require a response from the kernel
+  contain a 64-bit field used to pass a pointer to an output buffer.
+  Status is returned to userspace as the return value of the write()
+  system call.
+
+Resource management
+
+  Since creation and destruction of all IB resources is done by
+  commands passed through a file descriptor, the kernel can keep track
+  of which resources are attached to a given userspace context.  The
+  ib_uverbs module maintains idr tables that are used to translate
+  between kernel pointers and opaque userspace handles, so that kernel
+  pointers are never exposed to userspace and userspace cannot trick
+  the kernel into following a bogus pointer.
+
+  This also allows the kernel to clean up when a process exits and
+  prevent one process from touching another process's resources.
+
+Memory pinning
+
+  Direct userspace I/O requires that memory regions that are potential
+  I/O targets be kept resident at the same physical address.  The
+  ib_uverbs module manages pinning and unpinning memory regions via
+  get_user_pages() and put_page() calls.  It also accounts for the
+  amount of memory pinned in the process's locked_vm, and checks that
+  unprivileged processes do not exceed their RLIMIT_MEMLOCK limit.
+
+  Pages that are pinned multiple times are counted each time they are
+  pinned, so the value of locked_vm may be an overestimate of the
+  number of pages pinned by a process.
+
+/dev files
+
+  To create the appropriate character device files automatically with
+  udev, a rule like
+
+    KERNEL="uverbs*", NAME="infiniband/%k"
+
+  can be used.  This will create device nodes named
+
+    /dev/infiniband/uverbs0
+
+  and so on.  Since the InfiniBand userspace verbs should be safe for
+  use by non-privileged processes, it may be useful to add an
+  appropriate MODE or GROUP to the udev rule.

Subject: [PATCH] namespace.c: fix mnt_namespace clearing

This patch clears mnt_namespace on unmount.

Not clearing mnt_namespace has two effects:

   1) It is possible to attach a new mount to a detached mount,
      because check_mnt() returns true.

      This means, that when no other references to the detached mount
      remain, it still can't be freed.  This causes a resource leak,
      and possibly un-removable modules.

   2) If mnt_namespace is dereferenced (only in mark_mounts_for_expiry())
      after the namspace has been freed, it can cause an Oops, memory
      corruption, etc.

1) has been tested before and after the patch, 2) is only speculation.

Subject: [PATCH] namespace.c: fix race in mark_mounts_for_expiry()

This patch fixes a race found by Ram in mark_mounts_for_expiry() in
fs/namespace.c.

The bug can only be triggered with simultaneous exiting of a process having
a private namespace, and expiry of a mount from within that namespace.
It's practically impossible to trigger, and I haven't even tried.  But
still, a bug is a bug.

The race happens when put_namespace() is called by another task, while
mark_mounts_for_expiry() is between atomic_read() and get_namespace().  In
that case get_namespace() will be called on an already dead namespace with
unforeseeable results.

The solution was suggested by Al Viro, with his own words:

      Instead of screwing with atomic_read() in there, why don't we
      simply do the following:
      	a) atomic_dec_and_lock() in put_namespace()
      	b) __put_namespace() called without dropping lock
      	c) the first thing done by __put_namespace would be
      struct vfsmount *root = namespace->root;
      namespace->root = NULL;
      spin_unlock(...);
      ....
      umount_tree(root);
      ...
      	d) check in mark_... would be simply namespace && namespace->root.

      And we are all set; no screwing around with atomic_read(), no magic
      at all.  Dying namespace gets NULL ->root.
      All changes of ->root happen under spinlock.
      If under a spinlock we see non-NULL ->mnt_namespace, it won't be
      freed until we drop the lock (we will set ->mnt_namespace to NULL
      under that lock before we get to freeing namespace).
      If under a spinlock we see non-NULL ->mnt_namespace and
      ->mnt_namespace->root, we can grab a reference to namespace and be
      sure that it won't go away.

Subject: [PATCH] namespace.c: cleanup in mark_mounts_for_expiry()

This patch simplifies mark_mounts_for_expiry() by using detach_mnt() instead
of duplicating everything it does.

It should be an equivalent transformation except for righting the dput/mntput
order.

Al Viro said: "Looks sane".

Subject: [PATCH] namespace.c: fix expiring of detached mount

This patch fixes a bug noticed by Al Viro:

   However, we still have a problem here - just what would
   happen if vfsmount is detached while we were grabbing namespace
   semaphore?  Refcount alone is not useful here - we might be held by
   whoever had detached the vfsmount.  IOW, we should check that it's
   still attached (i.e. that mnt->mnt_parent != mnt).  If it's not -
   just leave it alone, do mntput() and let whoever holds it deal with
   the sucker.  No need to put it back on lists.

Subject: [PATCH] namespace.c: fix mnt_namespace zeroing for expired mounts

This patch clears mnt_namespace in an expired mount.

If mnt_namespace is not cleared, it's possible to attach a new mount to the
already detached mount, because check_mnt() can return true.

The effect is a resource leak, since the resulting tree will never be
freed.

This patch sets ->mnt_namespace where it's actually added to the
namespace.

Previously mnt_namespace was set in do_kern_mount() even if the filesystem
was never added to any process's namespace (most kernel-internal
filesystems).

This discrepancy doesn't actually cause any problems, but it's cleaner if
mnt_namespace is NULL for these non exported filesystems.

In addition the function doesn't even seem to be performance critical: it

Subject: [PATCH] dvb: core: fix race condition in FE_READ_STATUS ioctl

Fix a race condition where an application which issued a FE_READ_STATUS ioctl
directly after FE_SET_FRONTEND would see an old status, i.e.  FE_READ_STATUS
would be executed before the frontend thread has even seen the tungin request
from FE_SET_FRONTEND.

Subject: [PATCH] dvb: flexcop: woraround irq stop problem

The flexcop chip often stops generating interrupts after some hours of
operation.  Apparently this can be fixed by resetting register block 0x300 at
each channel change (this is not detailed in the flexcop data books).

This patch also restructures DMA handling and adds a bit of debug code for the
irq problem in case it still happens for someone.

From 7d53421c6adce47d067b834c605daeafe1ff9356 Mon Sep 17 00:00:00 2001
From: Manu Abraham <manu@kromtek.com>
Date: Thu, 7 Jul 2005 17:57:50 -0700
Subject: [PATCH] dvb: Twinhan DST: frontend fixes

o Make the inversion setting specific, ie, only for the 200103A DVB-S
  This should not be flagged on other cards.
o Make the frequency setting card specific
o Make the bandwidth setting generic such that it supports more DVB-T cards
o Set QAM size for DVB-C cards that do not autodetect QAM size
o Fix a bug that caused the polarization not to be set.
  Set polarization for cards that do not autodetect polarization
o Fix a bogus frontend signal lock, that caused a tuning delay as well.
o Make the Symbolrate setting card specific

Subject: [PATCH] dvb: ttpci: fix error handling for firmware communication

o make sure ERESTARTSYS will be propagated
o ReleaseBitmap: starting with Firmware 261e, also release when
  BMP_LOADING
o removes unused #define BMP_LOADINGS
o in many cases changed the return value from -1 to something more
  meaningful like ETIMEDOUT, EINVAL
o changed syslog message timeout waiting for COMMAND such that it
  indicates what command did not complete
o reduce # of arguments for LoadBitmap and BlitBitmap
o av7110_osd_cmd: remove the out: label

+/* DVB USB compliant linux driver for Conexant USB reference design.

+ * The Conexant reference design I saw on their website was only for analogue
+ * capturing (using the cx25842). The box I took to write this driver (reverse
+ * engineered) is the one labeled Medion MD95700. In addition to the cx25842
+ * for analogue capturing it also has a cx22702 DVB-T demodulator on the main
+ * board. Besides it has a atiremote (X10) and a USB2.0 hub onboard.
+ *
+ * Maybe it is a little bit premature to call this driver cxusb, but I assume
+ * the USB protocol is identical or at least inherited from the reference
+ * design, so it can be reused for the "analogue-only" device (if it will
+ * appear at all).
+ *
+ * TODO: check if the cx25840-driver (from ivtv) can be used for the analogue
+ * part
+ *
+ * FIXME: We're getting a lock and signal, but the isochronous transfer is empty
+ * for DVB-T.

Subject: [PATCH] dvb: usb/pci: correct syntax of driver name fields

Change the name-field of the pci_driver and usb_driver structs to the name of
the module after compilation.  It seems that this field is used in some places
where special characters are not allowed.  Thanks to Alan Halverson for
finding this problem.

 In general you need to load the bttv driver, which will handle the gpio and
-i2c communication for us, plus the common dvb-bt8xx device driver.

+TwinHan DST + clones (dst and dst-ca) are loaded automatically by the backend.
+For further details about TwinHan DST + clones see /Documentation/dvb/ci.txt.
 
-3a) Nebula / Pinnacle PCTV
---------------------------
+3a) The manual approach
+-----------------------
 
-   $ modprobe bttv (normally bttv is being loaded automatically by kmod)
-   $ modprobe dvb-bt8xx (or just place dvb-bt8xx in /etc/modules for automatic loading)
+Loading modules:
+modprobe bttv
+modprobe dvb-bt8xx
 
+Unloading modules:
+modprobe -r dvb-bt8xx
+modprobe -r bttv
 
-3b) TwinHan and Clones
+3b) The automatic approach
 --------------------------
 
-   $ modprobe bttv i2c_hw=1 card=0x71
-   $ modprobe dvb-bt8xx
-   $ modprobe dst
-
-The value 0x71 will override the PCI type detection for dvb-bt8xx,
-which is necessary for TwinHan cards.
-
-If you're having an older card (blue color circuit) and card=0x71 locks
-your machine, try using 0x68, too. If that does not work, ask on the
-mailing list.
-
-The DST module takes a couple of useful parameters:
+If not already done by installation, place a line either in
+/etc/modules.conf or in /etc/modprobe.conf containing this text:
+alias char-major-81	bttv
 
-a. verbose takes values 0 to 5. These values control the verbosity level.
-b. debug takes values 0 and 1. You can either disable or enable debugging.
-c. dst_addons takes values 0 and 0x20:
-- A value of 0 means it is a FTA card.
-- A value of 0x20 means it has a Conditional Access slot.
+Then place a line in /etc/modules containing this text:
+dvb-bt8xx
 
-The autodetected values are determined by the "response string"
-of the card, which you can see in your logs:
-e.g.: dst_get_device_id: Recognize [DSTMCI]
+Reboot your system and have fun!

Subject: [PATCH] v4l: cx88 hue offset fix

Changed hue offset to 128 to correct behavior in cx88 cards.  Previously,
setting 0% or 100% hue was required to avoid blue/green people on screen.
Now, 50% Hue means no offset, just like bt878 stuff.

- Correct sync byte for MPEG-2 transport stream packets.
- Add lgdt3302 as dependency of cx88-dvb in Kconfig.
- Add dvb support in v4l for DViCO FusionHDTV3 Gold-T using lgdt3302 frontend.
  This adds support for a different board from the previous (Gold-Q) patch.

Subject: [PATCH] pcmcia: fix i82365 request_region double usage

http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=f354942cb301fed273f423fb5c4f57bde3efc5b2
converted the check_region() calls in drivers/pcmcia/i82365.c into
request_regions.  Unfortunately this seems to have broken things.

isa_probe() used to call check_region() and then call add_pcic() which would
request_region().

Now isa_probe() calls request_region() and then calls add_pcic() which calls
request_region() again, this fails and add_pcic() returns immediately without
doing all the setup etc.

On the face of it the patch below fixes the problem, by not doing the second
request region in add_pcic().  I think this is preferable to remove the call
in isa_probe() since identify() touches the I/O regions and is called before
add_pcic().

However I haven't fully grokked the meaning of the code which follows the
request_region() in isa_probe(), so I'm not sure that the handling WRT
multiple sockets and multiple bridge chips is correct.  In particular I'm not
convinced that the regions for subsequent sockets and/or bridges will be
requested at all.  I suspect a more thorough reworking by someone who
understands what is going on there might be in order.

I should mention that I'm actually messing about with this on an ARM platform
with wacky memory and i/o mapping offsets etc, it doesn't quite work yet for
other reasons which preclude full testing etc, but I think the problem above
is still present for more normal x86 stuff.

Subject: [PATCH] pcmcia: deprecate ioctl

Schedule removal of the PCMCIA ioctl (and thus kernel support for the
pcmcia-cs userspace package) for November 2005.

A big "thank you" to Dave Hinds for his great work on supporting PCMCIA in
Linux.  Things are just done differently by now, so the ongoing work to make
PCMCIA behave like any other hotpluggable bus should continue.

From: Pavel Roskin <proski@gnu.org>
Date: Thu, 7 Jul 2005 17:59:03 -0700
Subject: [PATCH] pcmcia: remove client services version

The Linux PCMCIA code has some data that was apparently used (or meant to be
used) to ensure that only proper client drivers are loaded.  This is now
ensured (to a certain degree) by the fact that the most client drivers are
part of the kernel.  Also, the version information has not been updated
despite major changes in PCMCIA API.  This has made it meaningless.

This patch removes servinfo_t and pcmcia_get_card_services_info.  They are not
used in any userspace utilities such as pcmcia-cs and pcmciautils.
drivers/pcmcia/pcmcia_ioctl.c is adjusted accordingly.

CS_RELEASE and CS_RELEASE_CODE are removed.  include/pcmcia/version.h is empty
now.  It will be removed later, but for now it's left in the tree to avoid
touching all PCMCIA clients.

The only driver that needs to be changed is drivers/scsi/pcmcia/nsp_cs.c,
which uses CS_RELEASE_CODE.

Subject: [PATCH] pcmcia: remove client services version (fix)

One correction is needed.  Changes are not needed for
drivers/scsi/pcmcia/nsp_cs.c because it uses versioning in the
compatibility part, which is never used in 2.6 kernels.  The only right
thing we could to that compatibility code would be to remove it throughout
the file, but that would be a separate patch.

If probing for the correct interrupt fails on yenta bridges, the driver falls
back to polling for interrupt actions.  However, CardBus cards cannot be used
then.

Subject: [PATCH] nfsd4: fix sync'ing of recovery directory

We need to fsync the recovery directory after writing to it, but we weren't
doing this correctly.  (For example, we weren't taking the i_sem when calling
->fsync().)

Just reuse the existing nfsd fsync code instead.

Subject: [PATCH] nfsd4: stop overusing RECLAIM_BAD

A misreading of the spec lead us to convert all errors on open and lock
reclaims to RECLAIM_BAD.  This causes problems--for example, a reboot within
the grace period could lead to reclaims with stale stateid's, and we'd like to
return STALE errors in those cases.

What rfc3530 actually says about RECLAIM_BAD: "The reclaim provided by the
client does not match any of the server's state consistency checks and is
bad." I'm assuming that "state consistency checks" refers to checks for
consistency with the state recorded to stable storage, and that the error
should be reserved for that case.

Subject: [PATCH] nfsd4: fix open_reclaim seqid

The sequence number we store in the sequence id is the last one we received
from the client.  So on the next operation we'll check that the client gives
us the next higher number.

We increment sequence id's at the last moment, in encode, so that we're sure
of knowing the right error return.  (The decision to increment the sequence id
depends on the exact error returned.)

However on the *first* use of a sequence number, if we set the sequence number
to the one received from the client and then let the increment happen on
encode, we'll be left with a sequence number one to high.

For that reason, ENCODE_SEQID_OP_TAIL only increments the sequence id on
*confirmed* stateowners.

This creates a problem for open reclaims, which are confirmed on first use.
Therefore the open reclaim code, as a special exception, *decrements* the
sequence id, cancelling out the undesired increment on encode.  But this
prevents the sequence id from ever being incremented in the case where
multiple reclaims are sent with the same openowner.  Yuch!

We could add another exception to the open reclaim code, decrementing the
sequence id only if this is the first use of the open owner.

But it's simpler by far to modify the meaning of the op_seqid field: instead
of representing the previous value sent by the client, we take op_seqid, after
encoding, to represent the *next* sequence id that we expect from the client.
This eliminates the need for special-case handling of the first use of a
stateowner.

Subject: [PATCH] nfsd4: relax new lock seqid check

We're insisting that the lock sequence id field passed in the
open_to_lockowner struct always be zero.  This is probably thanks to the
sentence in rfc3530: "The first request issued for any given lock_owner is
issued with a sequence number of zero."

But there doesn't seem to be any problem with allowing initial sequence
numbers other than zero.  And currently this is causing lock reclaims from the
Linux client to fail.

In the spirit of "be liberal in what you accept, conservative in what you
send", we'll relax the check (and patch the Linux client as well).

from RFC 3530:
"Share reservations are established by OPEN operations and by their
nature are mandatory in that when the OPEN denies READ or WRITE
operations, that denial results in such operations being rejected
with error NFS4ERR_LOCKED."

(Note that share_denied is really only a legal error for OPEN.)

Subject: [PATCH] nfsd4: check lock type against openmode.

We shouldn't be allowing, e.g., write locks on files not open for read.  To
enforce this, we add a pointer from the lock stateid back to the open stateid
it came from, so that the check will continue to be correct even after the
open is upgraded or downgraded.

Subject: [PATCH] nfsd4: fix fh_expire_type

After discussion at the recent NFSv4 bake-a-thon, I realized that my
assumption that NFS4_FH_PERSISTENT required filehandles to persist was a
misreading of the spec.  This also fixes an interoperability problem with the
Solaris client.

Subject: [PATCH] m32r: framebuffer device support

This patch is for supporting Epson s1d13xxx framebuffer device for m32r.  #
Sorry, a little bigger.

The Epson s1d13806 is already supported by 2.6.12 kernel, and its driver is
placed as drivers/video/s1d13xxxfb.c.

For the m32r, a header file include/asm-m32r/s1d13806.h was prepared for
several m32r target platforms.  It was originally generated by an Epson
tool S1D13806CFG.EXE, and modified manually for the m32r platforms.

Set the target's split_io field when building a dm-mirror device so
incoming bios won't span the mirror's internal regions.  Without this,
regions can be accessed while not holding correct locks and data corruption
is possible.

Subject: [NET]: Transform skb_queue_len() binary tests into skb_queue_empty()

This is part of the grand scheme to eliminate the qlen
member of skb_queue_head, and subsequently remove the
'list' member of sk_buff.

Most users of skb_queue_len() want to know if the queue is
empty or not, and that's trivially done with skb_queue_empty()
which doesn't use the skb_queue_head->qlen member and instead
uses the queue list emptyness as the test.

Subject: [IPV4]: multicast API "join" issues

        This patch corrects a few problems with the IP_ADD_MEMBERSHIP
socket option:

1) The existing code makes an attempt at reference counting joins when
   using the ip_mreqn/imr_ifindex interface. Joining the same group
   on the same socket is an error, whatever the API. This leads to
   unexpected results when mixing ip_mreqn by index with ip_mreqn by
   address, ip_mreq, or other API's. For example, ip_mreq followed by
   ip_mreqn of the same group will "work" while the same two reversed
   will not.
           Fixed to always return EADDRINUSE on a duplicate join and
   removed the (now unused) reference count in ip_mc_socklist.

2) The group-search list in ip_mc_join_group() is comparing a full
   ip_mreqn structure and all of it must match for it to find the
   group. This doesn't correctly match a group that was joined with
   ip_mreq or ip_mreqn with an address (with or without an index). It
   also doesn't match groups that are joined by different addresses on
   the same interface. All of these are the same multicast group,
   which is identified by group address and interface index.
           Fixed the check to correctly match groups so we don't get
   duplicate group entries on the ip_mc_socklist.

3) The old code allocates a multicast address before searching for
   duplicates requiring it to free in various error cases. This
   patch moves the allocate until after the search and
   igmp_max_memberships check, so never a need to allocate, then free
   an entry.

Subject: [IPV4]: multicast API "join" issues

1) Changes IP_ADD_SOURCE_MEMBERSHIP and MCAST_JOIN_SOURCE_GROUP to ignore
   EADDRINUSE errors on a "courtesy join" -- prior membership or not
   is ok for these.

2) Adds "leave group" equivalence of (INCLUDE, empty) filters in the
   delta-based API. Without this, mixing delta-based API calls that
   end in an (INCLUDE, empty) filter would not allow a subsequent
   regular IP_ADD_MEMBERSHIP. It also frees socket buffer memory that
   isn't needed for both the multicast group record and source filter.

Subject: [IPV4]: fix IPv4 leave-group group matching

        This patch fixes the multicast group matching for
IP_DROP_MEMBERSHIP, similar to the IP_ADD_MEMBERSHIP fix in a prior
patch. Groups are identifiedby <group address,interface> and including
the interface address in the match will fail if a leave-group is done
by address when the join was done by index, or if different addresses
on the same interface are used in the join and leave.

Subject: [PATCH] ARM: 2796/1: Fix ARMv5[TEJ] check in MMU initalization

Patch from Deepak Saxena

The code in mm-armv.c checks for the condition (cpu_architecture()<= ARMv5)
in a few places but should be checking for ARMv5TEJ as the MMU is shared
across all v5 variations.

Date: Sun, 10 Jul 2005 19:58:08 +0100
Subject: [PATCH] ARM: 2798/1: OMAP update 2/11: Change ARM Kconfig to support
 omap1 and omap2

Patch from Tony Lindgren

This patch by Paul Mundt and other OMAP developers modifies
ARM specific Kconfig to allow sharing code between OMAP1 and
OMAP2 architectures.
In order to share code between OMAP1 and OMAP2, all OMAP1
specific code is moved into mach-omap1 directory in the
following patch. A new mach-omap2 directory will be added
later on.

- * interrupt is installed with the SA_INTERRUPT flag, which leaves all
- * interrupts masked at the CPU while an FPGA interrupt handler executes.

- * Limited testing indicates that this workaround appears to be effective
- * for the smc9194 Ethernet driver used on the Innovator.  It should work

Subject: [PATCH] Sync up ieee-1394

Lots of this patch is trivial code cleanups (static vars were being
intialized to 0, etc).

There's also some fixes for ISO transmits (max buffer handling).
Aswell, we have a few fixes to disable IRM capabilites correctly.  We've
also disabled, by default some generally unused EXPORT symbols for the
sake of cleanliness in the kernel.  However, instead of removing them
completely, we felt it necessary to have a config option that allowed
them to be enabled for the many projects outside of the main kernel tree
that use our API for driver development.

The primary reason for this patch is to revert a MODE6->MODE10 RBC
conversion patch from the SCSI maintainers.  The new conversions handled
directly in the scsi layer do not seem to work for SBP2.  This patch
reverts to our old working code so that users can enjoy using Firewire
disks and dvd drives again.

We are working with the SCSI maintainers to resolve this issue outside
of the main kernel tree.  We'll merge the patch once the SCSI layer's
handling of the MODE10 conversion is working for us.

Subject: [PATCH] remove asm-xtensa/ipc.h

Now that sys_ipc has been removed from xtensa, asm/ipc.h is no longer
needed for that architecture.  Not tested, but obviously correct.  This
file is included only from arch code and this patch also removes the only
inclusion.

+	  defined by each seccomp mode.

Subject: [SPARC64]: Pass regs and entry/exit boolean to syscall_trace()

Also fix a bug in 32-bit syscall tracing.  We forgot to update
this code when we moved over to the convention that all 32-bit
syscall arguments are zero extended by default.

Subject: [IA64] assign_irq_vector() should not panic

Current assign_irq_vector() will panic if interrupt vectors is running
out. But I think how to handle the case of lack of interrupt vectors
should be handled by the caller of this function. For example, some
PCI devices can raise the interrupt signal via both MSI and I/O
APIC. So even if the driver for these device fails to allocate a
vector for MSI, the driver still has a chance to use I/O APIC based
interrupt. But currently there is no chance for these driver to use
I/O APIC based interrupt because kernel will panic when
assign_irq_vector() fails to allocate interrupt vector.

The following patch changes assign_irq_vector() for ia64 to return
-ENOSPC on error instead of panic (as i386 and x86_64 versions do).

  A fifth-order polynomial fits the unofficial data (provided by Alex van

  numbers on my machine (ie. they agree with what my BIOS tells me).
  Here's the fifth-order fit to the 8-bit data:

Subject: [PATCH] I2C: New max6875 driver may corrupt EEPROMs

After a careful code analysis on the new max6875 driver
(drivers/i2c/chips/max6875.c), I have come to the conclusion that this
driver may cause EEPROM corruptions if used on random systems.

The EEPROM part of the MAX6875 chip is accessed using rather uncommon
I2C sequences. What is seen by the MAX6875 as reads can be seen by a
standard EEPROM (24C02) as writes. If you check the detection method
used by the driver, you'll find that the first SMBus command it will
send on the bus is i2c_smbus_write_byte_data(client, 0x80, 0x40). For
the MAX6875 it makes an internal pointer point to a specific offset of
the EEPROM waiting for a subsequent read command, so it's not an actual
data write operation, but for a standard EEPROM, this instead means
writing value 0x40 to offset 0x80. Blame Philips and Intel for the
obscure protocol.

Since the MAX6875 and the standard, common 24C02 EEPROMs share two I2C
addresses (0x50 and 0x52), loading the max6875 driver on a system with
standard EEPROMs at either address will trigger a write on these
EEPROMs, which will lead to their corruption if they happen not to be
write protected. This kind of EEPROMs can be found on memory modules
(SPD), ethernet adapters (MAC address), laptops (proprietary data) and
displays (EDID/DDC). Most of these are hopefully write-protected, but
not all of them.

For this reason, I would recommend that the max6875 driver be
neutralized, in a way that nobody can corrupt his/her EEPROMs by just
loading the driver. This means either deleting the driver completely, or
not listing any default address for it. I'd like this to be done before
2.6.13-rc1 is released.

Additionally, the max6875 driver lacks the 24RF08 corruption preventer
present in the eeprom driver, which means that loading this driver in a
system with such a chip would corrupt it as well.

Here is a proposed quick patch addressing the issue, although I wouldn't
mind a complete removal if it makes everyone feel safer. I think Ben
has plans to replace this driver by a much simplified one anyway.

Subject: [PATCH] w1: fix CRC calculation on bigendian platforms.

In the 2.6.13-rc1 code the "rn" structure is in the wrong-endianness
when passed to w1_attach_slave_device(). This causes problems like the
family and crc being swapped around.

Subject: [PATCH] I2C: Move hwmon drivers (2/3)

Part 2: Move the driver files themselves.

Note that the patch "adds trailing whitespace", because it does move the
files as-is, and some files happen to have trailing whitespace.

+ *
+ * The ADM1025 is a sensor chip made by Analog Devices. It reports up to 6
+ * voltages (including its own power source) and up to two temperatures
+ * (its own plus up to one external one). Voltages are scaled internally
+ * (which is not the common way) with ratios such that the nominal value
+ * of each voltage correspond to a register value of 192 (which means a
+ * resolution of about 0.5% of the nominal value). Temperature values are
+ * reported with a 1 deg resolution and a 3 deg accuracy. Complete
+ * datasheet can be obtained from Analog's website at:
+ *   http://www.analog.com/Analog_Root/productPage/productHome/0,2121,ADM1025,00.html
+ *
+ * This driver also supports the ADM1025A, which differs from the ADM1025
+ * only in that it has "open-drain VID inputs while the ADM1025 has
+ * on-chip 100k pull-ups on the VID inputs". It doesn't make any
+ * difference for us.
+ *
+ * This driver also supports the NE1619, a sensor chip made by Philips.
+ * That chip is similar to the ADM1025A, with a few differences. The only
+ * difference that matters to us is that the NE1619 has only two possible
+ * addresses while the ADM1025A has a third one. Complete datasheet can be
+ * obtained from Philips's website at:
+ *   http://www.semiconductors.philips.com/pip/NE1619DS.html
+ *
+ * Since the ADM1025 was the first chipset supported by this driver, most
+ * comments will refer to this chipset, but are actually general and
+ * concern all supported chipsets, unless mentioned otherwise.

+ * lm63.c - driver for the National Semiconductor LM63 temperature sensor
+ *          with integrated fan control
+ * Copyright (C) 2004-2005  Jean Delvare <khali@linux-fr.org>
+ * Based on the lm90 driver.
+ *
+ * The LM63 is a sensor chip made by National Semiconductor. It measures
+ * two temperatures (its own and one external one) and the speed of one
+ * fan, those speed it can additionally control. Complete datasheet can be
+ * obtained from National's website at:
+ *   http://www.national.com/pf/LM/LM63.html
+ *
+ * The LM63 is basically an LM86 with fan speed monitoring and control
+ * capabilities added. It misses some of the LM86 features though:
+ *  - No low limit for local temperature.
+ *  - No critical limit for local temperature.
+ *  - Critical limit for remote temperature can be changed only once. We
+ *    will consider that the critical limit is read-only.
+ *
+ * The datasheet isn't very clear about what the tachometer reading is.
+ * I had a explanation from National Semiconductor though. The two lower
+ * bits of the read value have to be masked out. The value is still 16 bit
+ * in width.
+ *

+ * Original port to Linux 2.6 by Jeff Oliver.
+ *
+ * The LM87 is a sensor chip made by National Semiconductor. It monitors up
+ * to 8 voltages (including its own power source), up to three temperatures
+ * (its own plus up to two external ones) and up to two fans. The default
+ * configuration is 6 voltages, two temperatures and two fans (see below).
+ * Voltages are scaled internally with ratios such that the nominal value of
+ * each voltage correspond to a register value of 192 (which means a
+ * resolution of about 0.5% of the nominal value). Temperature values are
+ * reported with a 1 deg resolution and a 3-4 deg accuracy. Complete
+ * datasheet can be obtained from National's website at:
+ *   http://www.national.com/pf/LM/LM87.html
+ *
+ * Some functions share pins, so not all functions are available at the same
+ * time. Which are depends on the hardware setup. This driver assumes that
+ * the BIOS configured the chip correctly. In that respect, it  differs from
+ * the original driver (from lm_sensors for Linux 2.4), which would force the
+ * LM87 to an arbitrary, compile-time chosen mode, regardless of the actual
+ * chipset wiring.
+ * For reference, here is the list of exclusive functions:
+ *  - in0+in5 (default) or temp3
+ *  - fan1 (default) or in6
+ *  - fan2 (default) or in7
+ *  - VID lines (default) or IRQ lines (not handled by this driver)
+ *
+ * The LM87 additionally features an analog output, supposedly usable to
+ * control the speed of a fan. All new chips use pulse width modulation
+ * instead. The LM87 is the only hardware monitoring chipset I know of
+ * which uses amplitude modulation. Be careful when using this feature.

+ * lm90.c - Part of lm_sensors, Linux kernel modules for hardware
+ *          monitoring
+ * Copyright (C) 2003-2005  Jean Delvare <khali@linux-fr.org>
+ *
+ * Based on the lm83 driver. The LM90 is a sensor chip made by National
+ * Semiconductor. It reports up to two temperatures (its own plus up to
+ * one external one) with a 0.125 deg resolution (1 deg for local
+ * temperature) and a 3-4 deg accuracy. Complete datasheet can be
+ * obtained from National's website at:
+ *   http://www.national.com/pf/LM/LM90.html
+ *
+ * This driver also supports the LM89 and LM99, two other sensor chips
+ * made by National Semiconductor. Both have an increased remote
+ * temperature measurement accuracy (1 degree), and the LM99
+ * additionally shifts remote temperatures (measured and limits) by 16
+ * degrees, which allows for higher temperatures measurement. The
+ * driver doesn't handle it since it can be done easily in user-space.
+ * Complete datasheets can be obtained from National's website at:
+ *   http://www.national.com/pf/LM/LM89.html
+ *   http://www.national.com/pf/LM/LM99.html
+ * Note that there is no way to differentiate between both chips.
+ *
+ * This driver also supports the LM86, another sensor chip made by
+ * National Semiconductor. It is exactly similar to the LM90 except it
+ * has a higher accuracy.
+ * Complete datasheet can be obtained from National's website at:
+ *   http://www.national.com/pf/LM/LM86.html
+ *
+ * This driver also supports the ADM1032, a sensor chip made by Analog
+ * Devices. That chip is similar to the LM90, with a few differences
+ * that are not handled by this driver. Complete datasheet can be
+ * obtained from Analog's website at:
+ *   http://products.analog.com/products/info.asp?product=ADM1032
+ * Among others, it has a higher accuracy than the LM90, much like the
+ * LM86 does.
+ *
+ * This driver also supports the MAX6657, MAX6658 and MAX6659 sensor
+ * chips made by Maxim. These chips are similar to the LM86. Complete
+ * datasheet can be obtained at Maxim's website at:
+ *   http://www.maxim-ic.com/quick_view2.cfm/qv_pk/2578
+ * Note that there is no easy way to differentiate between the three
+ * variants. The extra address and features of the MAX6659 are not
+ * supported by this driver.
+ *
+ * This driver also supports the ADT7461 chip from Analog Devices but
+ * only in its "compatability mode". If an ADT7461 chip is found but
+ * is configured in non-compatible mode (where its temperature
+ * register values are decoded differently) it is ignored by this
+ * driver. Complete datasheet can be obtained from Analog's website
+ * at:
+ *   http://products.analog.com/products/info.asp?product=ADT7461
+ *
+ * Since the LM90 was the first chipset supported by this driver, most
+ * comments will refer to this chipset, but are actually general and
+ * concern all supported chipsets, unless mentioned otherwise.

+ * lm92 - Hardware monitoring driver
+ * Copyright (C) 2005  Jean Delvare <khali@linux-fr.org>
+ *
+ * Based on the lm90 driver, with some ideas taken from the lm_sensors
+ * lm92 driver as well.
+ *
+ * The LM92 is a sensor chip made by National Semiconductor. It reports
+ * its own temperature with a 0.0625 deg resolution and a 0.33 deg
+ * accuracy. Complete datasheet can be obtained from National's website
+ * at:
+ *   http://www.national.com/pf/LM/LM92.html
+ *
+ * This driver also supports the MAX6635 sensor chip made by Maxim.
+ * This chip is compatible with the LM92, but has a lesser accuracy
+ * (1.0 deg). Complete datasheet can be obtained from Maxim's website
+ * at:
+ *   http://www.maxim-ic.com/quick_view2.cfm/qv_pk/3074
+ *
+ * Since the LM92 was the first chipset supported by this driver, most
+ * comments will refer to this chipset, but are actually general and
+ * concern all supported chipsets, unless mentioned otherwise.
+ *
+ * Support could easily be added for the National Semiconductor LM76
+ * and Maxim MAX6633 and MAX6634 chips, which are mostly compatible
+ * with the LM92.

+
+ Alas, none of the elegant function-fit solutions will work because we
+ aren't allowed to use floating point in the kernel and doing it with
+ integers doesn't provide enough precision.  So we'll do boring old
+ look-up table stuff.  The unofficial data (see below) have effectively
+ 7-bit resolution (they are rounded to the nearest degree).  I'm assuming
+ that the transfer function of the device is monotonic and smooth, so a
+ smooth function fit to the data will allow us to get better precision.
+ I used the 5th-order poly fit described above and solved for
+ VIA register values 0-255.  I *10 before rounding, so we get tenth-degree
+ precision.  (I could have done all 1024 values for our 10-bit readings,
+ but the function is very linear in the useful range (0-80 deg C), so
+ we'll just use linear interpolation for 10-bit readings.)  So, tempLUT
+ is the temp at via register values 0-255: */

+
+    This is a preliminary version of the driver, only supporting the
+    fan and temperature inputs. The chip does much more than that.

- * The ADM1025 is a sensor chip made by Analog Devices. It reports up to 6
- * voltages (including its own power source) and up to two temperatures
- * (its own plus up to one external one). Voltages are scaled internally
- * (which is not the common way) with ratios such that the nominal value
- * of each voltage correspond to a register value of 192 (which means a
- * resolution of about 0.5% of the nominal value). Temperature values are
- * reported with a 1 deg resolution and a 3 deg accuracy. Complete
- * datasheet can be obtained from Analog's website at:
- *   http://www.analog.com/Analog_Root/productPage/productHome/0,2121,ADM1025,00.html
- *
- * This driver also supports the ADM1025A, which differs from the ADM1025
- * only in that it has "open-drain VID inputs while the ADM1025 has
- * on-chip 100k pull-ups on the VID inputs". It doesn't make any
- * difference for us.
- *
- * This driver also supports the NE1619, a sensor chip made by Philips.
- * That chip is similar to the ADM1025A, with a few differences. The only
- * difference that matters to us is that the NE1619 has only two possible
- * addresses while the ADM1025A has a third one. Complete datasheet can be
- * obtained from Philips's website at:
- *   http://www.semiconductors.philips.com/pip/NE1619DS.html
- *
- * Since the ADM1025 was the first chipset supported by this driver, most
- * comments will refer to this chipset, but are actually general and
- * concern all supported chipsets, unless mentioned otherwise.

- * with no real benefit.

- * lm63.c - driver for the National Semiconductor LM63 temperature sensor
- *          with integrated fan control
- * Copyright (C) 2004-2005  Jean Delvare <khali@linux-fr.org>
- * Based on the lm90 driver.
- *
- * The LM63 is a sensor chip made by National Semiconductor. It measures
- * two temperatures (its own and one external one) and the speed of one
- * fan, those speed it can additionally control. Complete datasheet can be
- * obtained from National's website at:
- *   http://www.national.com/pf/LM/LM63.html
- *
- * The LM63 is basically an LM86 with fan speed monitoring and control
- * capabilities added. It misses some of the LM86 features though:
- *  - No low limit for local temperature.
- *  - No critical limit for local temperature.
- *  - Critical limit for remote temperature can be changed only once. We
- *    will consider that the critical limit is read-only.
- *
- * The datasheet isn't very clear about what the tachometer reading is.
- * I had a explanation from National Semiconductor though. The two lower
- * bits of the read value have to be masked out. The value is still 16 bit
- * in width.

-   may be both present on the SMBus and the ISA bus, and we have to handle
-   those cases separately at some places. Second, there might be several
-   LM78 chips available (well, actually, that is probably never done; but
-   it is a clean illustration of how to handle a case like that). Finally,
-   a specific chip may be attached to *both* ISA and SMBus, and we would
-   not like to detect it double. Fortunately, in the case of the LM78 at
-   least, a register tells us what SMBus address we are on, so that helps
-   a bit - except if there could be more than one SMBus. Groan. No solution

- * Original port to Linux 2.6 by Jeff Oliver.
- *
- * The LM87 is a sensor chip made by National Semiconductor. It monitors up
- * to 8 voltages (including its own power source), up to three temperatures
- * (its own plus up to two external ones) and up to two fans. The default
- * configuration is 6 voltages, two temperatures and two fans (see below).
- * Voltages are scaled internally with ratios such that the nominal value of
- * each voltage correspond to a register value of 192 (which means a
- * resolution of about 0.5% of the nominal value). Temperature values are
- * reported with a 1 deg resolution and a 3-4 deg accuracy. Complete
- * datasheet can be obtained from National's website at:
- *   http://www.national.com/pf/LM/LM87.html
- *
- * Some functions share pins, so not all functions are available at the same
- * time. Which are depends on the hardware setup. This driver assumes that
- * the BIOS configured the chip correctly. In that respect, it  differs from
- * the original driver (from lm_sensors for Linux 2.4), which would force the
- * LM87 to an arbitrary, compile-time chosen mode, regardless of the actual
- * chipset wiring.
- * For reference, here is the list of exclusive functions:
- *  - in0+in5 (default) or temp3
- *  - fan1 (default) or in6
- *  - fan2 (default) or in7
- *  - VID lines (default) or IRQ lines (not handled by this driver)
- *
- * The LM87 additionally features an analog output, supposedly usable to
- * control the speed of a fan. All new chips use pulse width modulation
- * instead. The LM87 is the only hardware monitoring chipset I know of
- * which uses amplitude modulation. Be careful when using this feature.

- * lm90.c - Part of lm_sensors, Linux kernel modules for hardware
- *          monitoring
- * Copyright (C) 2003-2005  Jean Delvare <khali@linux-fr.org>
- *
- * Based on the lm83 driver. The LM90 is a sensor chip made by National
- * Semiconductor. It reports up to two temperatures (its own plus up to
- * one external one) with a 0.125 deg resolution (1 deg for local
- * temperature) and a 3-4 deg accuracy. Complete datasheet can be
- * obtained from National's website at:
- *   http://www.national.com/pf/LM/LM90.html
- *
- * This driver also supports the LM89 and LM99, two other sensor chips
- * made by National Semiconductor. Both have an increased remote
- * temperature measurement accuracy (1 degree), and the LM99
- * additionally shifts remote temperatures (measured and limits) by 16
- * degrees, which allows for higher temperatures measurement. The
- * driver doesn't handle it since it can be done easily in user-space.
- * Complete datasheets can be obtained from National's website at:
- *   http://www.national.com/pf/LM/LM89.html
- *   http://www.national.com/pf/LM/LM99.html
- * Note that there is no way to differentiate between both chips.
- *
- * This driver also supports the LM86, another sensor chip made by
- * National Semiconductor. It is exactly similar to the LM90 except it
- * has a higher accuracy.
- * Complete datasheet can be obtained from National's website at:
- *   http://www.national.com/pf/LM/LM86.html
- *
- * This driver also supports the ADM1032, a sensor chip made by Analog
- * Devices. That chip is similar to the LM90, with a few differences
- * that are not handled by this driver. Complete datasheet can be
- * obtained from Analog's website at:
- *   http://products.analog.com/products/info.asp?product=ADM1032
- * Among others, it has a higher accuracy than the LM90, much like the
- * LM86 does.
- *
- * This driver also supports the MAX6657, MAX6658 and MAX6659 sensor
- * chips made by Maxim. These chips are similar to the LM86. Complete
- * datasheet can be obtained at Maxim's website at:
- *   http://www.maxim-ic.com/quick_view2.cfm/qv_pk/2578
- * Note that there is no easy way to differentiate between the three
- * variants. The extra address and features of the MAX6659 are not
- * supported by this driver.
- *
- * This driver also supports the ADT7461 chip from Analog Devices but
- * only in its "compatability mode". If an ADT7461 chip is found but
- * is configured in non-compatible mode (where its temperature
- * register values are decoded differently) it is ignored by this
- * driver. Complete datasheet can be obtained from Analog's website
- * at:
- *   http://products.analog.com/products/info.asp?product=ADT7461

- * lm92 - Hardware monitoring driver
- * Copyright (C) 2005  Jean Delvare <khali@linux-fr.org>
- *
- * Based on the lm90 driver, with some ideas taken from the lm_sensors
- * lm92 driver as well.
- *
- * The LM92 is a sensor chip made by National Semiconductor. It reports
- * its own temperature with a 0.0625 deg resolution and a 0.33 deg
- * accuracy. Complete datasheet can be obtained from National's website
- * at:
- *   http://www.national.com/pf/LM/LM92.html
- *
- * This driver also supports the MAX6635 sensor chip made by Maxim.
- * This chip is compatible with the LM92, but has a lesser accuracy
- * (1.0 deg). Complete datasheet can be obtained from Maxim's website
- * at:
- *   http://www.maxim-ic.com/quick_view2.cfm/qv_pk/3074
- *
- * Since the LM92 was the first chipset supported by this driver, most
- * comments will refer to this chipset, but are actually general and
- * concern all supported chipsets, unless mentioned otherwise.
- *
- * Support could easily be added for the National Semiconductor LM76
- * and Maxim MAX6633 and MAX6634 chips, which are mostly compatible
- * with the LM92.

- A fifth-order polynomial fits the unofficial data (provided by Alex van

- Alas, none of the elegant function-fit solutions will work because we
- aren't allowed to use floating point in the kernel and doing it with
- integers doesn't provide enough precision.  So we'll do boring old
- look-up table stuff.  The unofficial data (see below) have effectively
- 7-bit resolution (they are rounded to the nearest degree).  I'm assuming
- that the transfer function of the device is monotonic and smooth, so a
- smooth function fit to the data will allow us to get better precision.
- I used the 5th-order poly fit described above and solved for
- VIA register values 0-255.  I *10 before rounding, so we get tenth-degree
- precision.  (I could have done all 1024 values for our 10-bit readings,
- but the function is very linear in the useful range (0-80 deg C), so
- we'll just use linear interpolation for 10-bit readings.)  So, tempLUT
- is the temp at via register values 0-255: */

- Here's the reverse LUT.  I got it by doing a 6-th order poly fit (needed
- an extra term for a good fit to these inverse data!) and then
- solving for each temp value from -50 to 110 (the useable range for
- this chip).  Here's the fit:

From ede7fbdf526c314850c9f32dd8da1753bf8d0ad5 Mon Sep 17 00:00:00 2001
From: Jean Delvare <khali@linux-fr.org>
Date: Sat, 2 Jul 2005 18:52:48 +0200
Subject: [PATCH] I2C: Move hwmon drivers (3/3)

Part 3: Move the drivers documentation, plus two general documentation
files.

Note that the patch "adds trailing whitespace", because it does move the
files as-is, and some files happen to have trailing whitespace.

+Module Parameters
+-----------------
+
+* read_only: int
+  Don't set any values, read only mode
+
+
+Description
+-----------
+
+The chips supported by this driver are very similar. The Maxim MAX1617 is
+the oldest; it has the problem that it is not very well detectable. The
+MAX1617A solves that. The ADM1021 is a straight clone of the MAX1617A.
+Ditto for the THMC10. From here on, we will refer to all these chips as
+ADM1021-clones.
+
+The ADM1021 and MAX1617A reports a die code, which is a sort of revision
+code. This can help us pinpoint problems; it is not very useful
+otherwise.
+
+ADM1021-clones implement two temperature sensors. One of them is internal,
+and measures the temperature of the chip itself; the other is external and
+is realised in the form of a transistor-like device. A special alarm
+indicates whether the remote sensor is connected.
+
+Each sensor has its own low and high limits. When they are crossed, the
+corresponding alarm is set and remains on as long as the temperature stays
+out of range. Temperatures are measured in degrees Celsius. Measurements
+are possible between -65 and +127 degrees, with a resolution of one degree.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared!
+
+This driver only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values. It is possible to make
+ADM1021-clones do faster measurements, but there is really no good reason
+for that.
+
+Xeon support
+------------
+
+Some Xeon processors have real max1617, adm1021, or compatible chips
+within them, with two temperature sensors.
+
+Other Xeons have chips with only one sensor.
+
+If you have a Xeon, and the adm1021 module loads, and both temperatures
+appear valid, then things are good.
+
+If the adm1021 module doesn't load, you should try this:
+	modprobe adm1021 force_adm1021=BUS,ADDRESS
+	ADDRESS can only be 0x18, 0x1a, 0x29, 0x2b, 0x4c, or 0x4e.
+
+If you have dual Xeons you may have appear to have two separate
+adm1021-compatible chips, or two single-temperature sensors, at distinct
+addresses.

+
+Description
+-----------
+
+(This is from Analog Devices.) The ADM1025 is a complete system hardware
+monitor for microprocessor-based systems, providing measurement and limit
+comparison of various system parameters. Five voltage measurement inputs
+are provided, for monitoring +2.5V, +3.3V, +5V and +12V power supplies and
+the processor core voltage. The ADM1025 can monitor a sixth power-supply
+voltage by measuring its own VCC. One input (two pins) is dedicated to a
+remote temperature-sensing diode and an on-chip temperature sensor allows
+ambient temperature to be monitored.
+
+One specificity of this chip is that the pin 11 can be hardwired in two
+different manners. It can act as the +12V power-supply voltage analog
+input, or as the a fifth digital entry for the VID reading (bit 4). It's
+kind of strange since both are useful, and the reason for designing the
+chip that way is obscure at least to me. The bit 5 of the configuration
+register can be used to define how the chip is hardwired. Please note that
+it is not a choice you have to make as the user. The choice was already
+made by your motherboard's maker. If the configuration bit isn't set
+properly, you'll have a wrong +12V reading or a wrong VID reading. The way
+the driver handles that is to preserve this bit through the initialization
+process, assuming that the BIOS set it up properly beforehand. If it turns
+out not to be true in some cases, we'll provide a module parameter to force
+modes.
+
+This driver also supports the ADM1025A, which differs from the ADM1025
+only in that it has "open-drain VID inputs while the ADM1025 has on-chip
+100k pull-ups on the VID inputs". It doesn't make any difference for us.

+Description
+-----------
+
+This driver implements support for the Analog Devices ADM1026. Analog
+Devices calls it a "complete thermal system management controller."
+
+The ADM1026 implements three (3) temperature sensors, 17 voltage sensors,
+16 general purpose digital I/O lines, eight (8) fan speed sensors (8-bit),
+an analog output and a PWM output along with limit, alarm and mask bits for
+all of the above. There is even 8k bytes of EEPROM memory on chip.
+
+Temperatures are measured in degrees Celsius. There are two external
+sensor inputs and one internal sensor. Each sensor has a high and low
+limit. If the limit is exceeded, an interrupt (#SMBALERT) can be
+generated. The interrupts can be masked. In addition, there are over-temp
+limits for each sensor. If this limit is exceeded, the #THERM output will
+be asserted. The current temperature and limits have a resolution of 1
+degree.
+
+Fan rotation speeds are reported in RPM (rotations per minute) but measured
+in counts of a 22.5kHz internal clock. Each fan has a high limit which
+corresponds to a minimum fan speed. If the limit is exceeded, an interrupt
+can be generated. Each fan can be programmed to divide the reference clock
+by 1, 2, 4 or 8. Not all RPM values can accurately be represented, so some
+rounding is done. With a divider of 8, the slowest measurable speed of a
+two pulse per revolution fan is 661 RPM.
+
+There are 17 voltage sensors. An alarm is triggered if the voltage has
+crossed a programmable minimum or maximum limit. Note that minimum in this
+case always means 'closest to zero'; this is important for negative voltage
+measurements. Several inputs have integrated attenuators so they can measure
+higher voltages directly. 3.3V, 5V, 12V, -12V and battery voltage all have
+dedicated inputs. There are several inputs scaled to 0-3V full-scale range
+for SCSI terminator power. The remaining inputs are not scaled and have
+a 0-2.5V full-scale range. A 2.5V or 1.82V reference voltage is provided
+for negative voltage measurements.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared! Note that in the current implementation, all hardware
+registers are read whenever any data is read (unless it is less than 2.0
+seconds since the last update). This means that you can easily miss
+once-only alarms.
+
+The ADM1026 measures continuously. Analog inputs are measured about 4
+times a second. Fan speed measurement time depends on fan speed and
+divisor. It can take as long as 1.5 seconds to measure all fan speeds.
+
+The ADM1026 has the ability to automatically control fan speed based on the
+temperature sensor inputs. Both the PWM output and the DAC output can be
+used to control fan speed. Usually only one of these two outputs will be
+used. Write the minimum PWM or DAC value to the appropriate control
+register. Then set the low temperature limit in the tmin values for each
+temperature sensor. The range of control is fixed at 20 °C, and the
+largest difference between current and tmin of the temperature sensors sets
+the control output. See the datasheet for several example circuits for
+controlling fan speed with the PWM and DAC outputs. The fan speed sensors
+do not have PWM compensation, so it is probably best to control the fan
+voltage from the power lead rather than on the ground lead.
+
+The datasheet shows an example application with VID signals attached to
+GPIO lines. Unfortunately, the chip may not be connected to the VID lines
+in this way. The driver assumes that the chips *is* connected this way to
+get a VID voltage.

+
+Interface
+---------
+The I2C addresses listed above assume BIOS has not changed the
+chip MSB 5-bit address. Each chip reports a unique manufacturer
+identification code as well as the chip revision/stepping level.
+
+Description
+-----------
+[From ADM9240] The ADM9240 is a complete system hardware monitor for
+microprocessor-based systems, providing measurement and limit comparison
+of up to four power supplies and two processor core voltages, plus
+temperature, two fan speeds and chassis intrusion. Measured values can
+be read out via an I2C-compatible serial System Management Bus, and values
+for limit comparisons can be programmed in over the same serial bus. The
+high speed successive approximation ADC allows frequent sampling of all
+analog channels to ensure a fast interrupt response to any out-of-limit
+measurement.
+
+The ADM9240, DS1780 and LM81 are register compatible, the following
+details are common to the three chips. Chip differences are described
+after this section.
+
+
+Measurements
+------------
+The measurement cycle
+
+The adm9240 driver will take a measurement reading no faster than once
+each two seconds. User-space may read sysfs interface faster than the
+measurement update rate and will receive cached data from the most
+recent measurement.
+
+ADM9240 has a very fast 320us temperature and voltage measurement cycle
+with independent fan speed measurement cycles counting alternating rising
+edges of the fan tacho inputs.
+
+DS1780 measurement cycle is about once per second including fan speed.
+
+LM81 measurement cycle is about once per 400ms including fan speed.
+The LM81 12-bit extended temperature measurement mode is not supported.
+
+Temperature
+-----------
+On chip temperature is reported as degrees Celsius as 9-bit signed data
+with resolution of 0.5 degrees Celsius. High and low temperature limits
+are 8-bit signed data with resolution of one degree Celsius.
+
+Temperature alarm is asserted once the temperature exceeds the high limit,
+and is cleared when the temperature falls below the temp1_max_hyst value.
+
+Fan Speed
+---------
+Two fan tacho inputs are provided, the ADM9240 gates an internal 22.5kHz
+clock via a divider to an 8-bit counter. Fan speed (rpm) is calculated by:
+
+rpm = (22500 * 60) / (count * divider)
+
+Automatic fan clock divider
+
+  * User sets 0 to fan_min limit
+    - low speed alarm is disabled
+    - fan clock divider not changed
+    - auto fan clock adjuster enabled for valid fan speed reading
+
+  * User sets fan_min limit too low
+    - low speed alarm is enabled
+    - fan clock divider set to max
+    - fan_min set to register value 254 which corresponds
+      to 664 rpm on adm9240
+    - low speed alarm will be asserted if fan speed is
+      less than minimum measurable speed
+    - auto fan clock adjuster disabled
+
+  * User sets reasonable fan speed
+    - low speed alarm is enabled
+    - fan clock divider set to suit fan_min
+    - auto fan clock adjuster enabled: adjusts fan_min
+
+  * User sets unreasonably high low fan speed limit
+    - resolution of the low speed limit may be reduced
+    - alarm will be asserted
+    - auto fan clock adjuster enabled: adjusts fan_min
+
+    * fan speed may be displayed as zero until the auto fan clock divider
+      adjuster brings fan speed clock divider back into chip measurement
+      range, this will occur within a few measurement cycles.
+
+Analog Output
+-------------
+An analog output provides a 0 to 1.25 volt signal intended for an external
+fan speed amplifier circuit. The analog output is set to maximum value on
+power up or reset. This doesn't do much on the test Intel SE440BX-2.
+
+Voltage Monitor
+
+Voltage (IN) measurement is internally scaled:
+
+    nr  label       nominal     maximum   resolution
+                      mV          mV         mV
+    0   +2.5V        2500        3320       13.0
+    1   Vccp1        2700        3600       14.1
+    2   +3.3V        3300        4380       17.2
+    3     +5V        5000        6640       26.0
+    4    +12V       12000       15940       62.5
+    5   Vccp2        2700        3600       14.1
+
+The reading is an unsigned 8-bit value, nominal voltage measurement is
+represented by a reading of 192, being 3/4 of the measurement range.
+
+An alarm is asserted for any voltage going below or above the set limits.
+
+The driver reports and accepts voltage limits scaled to the above table.
+
+VID Monitor
+-----------
+The chip has five inputs to read the 5-bit VID and reports the mV value
+based on detected CPU type.
+
+Chassis Intrusion
+-----------------
+An alarm is asserted when the CI pin goes active high. The ADM9240
+Datasheet has an example of an external temperature sensor driving
+this pin. On an Intel SE440BX-2 the Chassis Intrusion header is
+connected to a normally open switch.
+
+The ADM9240 provides an internal open drain on this line, and may output
+a 20 ms active low pulse to reset an external Chassis Intrusion latch.
+
+Clear the CI latch by writing value 1 to the sysfs chassis_clear file.
+
+Alarm flags reported as 16-bit word
+
+    bit     label               comment

+     9      VCCP2_Error         high or low limit exceeded
+    12      Chassis_Error       CI pin went high
+
+Remaining bits are reserved and thus undefined. It is important to note
+that alarm bits may be cleared on read, user-space may latch alarms and
+provide the end-user with a method to clear alarm memory.

+Author: Mark M. Hoffman <mhoffman@lightlink.com>
+
+Description
+-----------
+
+This driver implements support for the Asus ASB100 and ASB100-A "Bach".
+These are custom ASICs available only on Asus mainboards. Asus refuses to
+supply a datasheet for these chips. Thanks go to many people who helped
+investigate their hardware, including:
+
+Vitaly V. Bursov
+Alexander van Kaam (author of MBM for Windows)
+Bertrik Sikken
+
+The ASB100 implements seven voltage sensors, three fan rotation speed
+sensors, four temperature sensors, VID lines and alarms. In addition to
+these, the ASB100-A also implements a single PWM controller for fans 2 and
+3 (i.e. one setting controls both.) If you have a plain ASB100, the PWM
+controller will simply not work (or maybe it will for you... it doesn't for
+me).
+
+Temperatures are measured and reported in degrees Celsius.
+
+Fan speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit.
+
+Voltage sensors (also known as IN sensors) report values in volts.
+
+The VID lines encode the core voltage value: the voltage level your
+processor should work with. This is hardcoded by the mainboard and/or
+processor itself. It is a value in volts.
+
+Alarms: (TODO question marks indicate may or may not work)
+
+0x0001 => in0 (?)
+0x0002 => in1 (?)
+0x0004 => in2
+0x0008 => in3
+0x0010 => temp1 (1)
+0x0020 => temp2

+0x0400 => in6 (?) (2)
+0x0800 => fan3
+0x1000 => chassis switch
+0x2000 => temp3
+
+Alarm Notes:
+
+(1) This alarm will only trigger if the hysteresis value is 127C.
+I.e. it behaves the same as w83781d.
+
+(2) The min and max registers for these values appear to
+be read-only or otherwise stuck at 0x00.
+
+TODO:
+* Experiment with fan divisors > 8.
+* Experiment with temp. sensor types.
+* Are there really 13 voltage inputs? Probably not...
+* Cleanups, no doubt...

+Module Parameters
+------------------
+
+* polarity int
+  Output's polarity: 0 = active high, 1 = active low
+
+Description
+-----------
+
+The DS1621 is a (one instance) digital thermometer and thermostat. It has
+both high and low temperature limits which can be user defined (i.e.
+programmed into non-volatile on-chip registers). Temperature range is -55
+degree Celsius to +125 in 0.5 increments. You may convert this into a
+Fahrenheit range of -67 to +257 degrees with 0.9 steps. If polarity
+parameter is not provided, original value is used.
+
+As for the thermostat, behavior can also be programmed using the polarity
+toggle. On the one hand ("heater"), the thermostat output of the chip,
+Tout, will trigger when the low limit temperature is met or underrun and
+stays high until the high limit is met or exceeded. On the other hand
+("cooler"), vice versa. That way "heater" equals "active low", whereas
+"conditioner" equals "active high". Please note that the DS1621 data sheet
+is somewhat misleading in this point since setting the polarity bit does
+not simply invert Tout.
+
+A second thing is that, during extensive testing, Tout showed a tolerance
+of up to +/- 0.5 degrees even when compared against precise temperature
+readings. Be sure to have a high vs. low temperature limit gap of al least
+1.0 degree Celsius to avoid Tout "bouncing", though!
+
+As for alarms, you can read the alarm status of the DS1621 via the 'alarms'
+/sys file interface. The result consists mainly of bit 6 and 5 of the
+configuration register of the chip; bit 6 (0x40 or 64) is the high alarm
+bit and bit 5 (0x20 or 32) the low one. These bits are set when the high or
+low limits are met or exceeded and are reset by the module as soon as the
+respective temperature ranges are left.
+
+The alarm registers are in no way suitable to find out about the actual
+status of Tout. They will only tell you about its history, whether or not
+any of the limits have ever been met or exceeded since last power-up or
+reset. Be aware: When testing, it showed that the status of Tout can change
+with neither of the alarms set.
+
+Temperature conversion of the DS1621 takes up to 1000ms; internal access to
+non-volatile registers may last for 10ms or below.
+
+High Accuracy Temperature Reading
+---------------------------------
+
+As said before, the temperature issued via the 9-bit i2c-bus data is
+somewhat arbitrary. Internally, the temperature conversion is of a
+different kind that is explained (not so...) well in the DS1621 data sheet.
+To cut the long story short: Inside the DS1621 there are two oscillators,
+both of them biassed by a temperature coefficient.
+
+Higher resolution of the temperature reading can be achieved using the
+internal projection, which means taking account of REG_COUNT and REG_SLOPE
+(the driver manages them):
+
+Taken from Dallas Semiconductors App Note 068: 'Increasing Temperature
+Resolution on the DS1620' and App Note 105: 'High Resolution Temperature
+Measurement with Dallas Direct-to-Digital Temperature Sensors'
+
+- Read the 9-bit temperature and strip the LSB (Truncate the .5 degs)
+- The resulting value is TEMP_READ.
+- Then, read REG_COUNT.
+- And then, REG_SLOPE.
+
+      TEMP = TEMP_READ - 0.25 + ((REG_SLOPE - REG_COUNT) / REG_SLOPE)
+
+Note that this is what the DONE bit in the DS1621 configuration register is
+good for: Internally, one temperature conversion takes up to 1000ms. Before
+that conversion is complete you will not be able to read valid things out
+of REG_COUNT and REG_SLOPE. The DONE bit, as you may have guessed by now,
+tells you whether the conversion is complete ("done", in plain English) and
+thus, whether the values you read are good or not.
+
+The DS1621 has two modes of operation: "Continuous" conversion, which can
+be understood as the default stand-alone mode where the chip gets the
+temperature and controls external devices via its Tout pin or tells other
+i2c's about it if they care. The other mode is called "1SHOT", that means
+that it only figures out about the temperature when it is explicitly told
+to do so; this can be seen as power saving mode.
+
+Now if you want to read REG_COUNT and REG_SLOPE, you have to either stop
+the continuous conversions until the contents of these registers are valid,
+or, in 1SHOT mode, you have to have one conversion made.

+
+Authors:
+        Reinhard Nissl <rnissl@gmx.de> based on work

+
+Description
+-----------
+
+This driver implements support for the Fujitsu-Siemens Hermes chip. It is
+described in the 'Register Set Specification BMC Hermes based Systemboard'
+from Fujitsu-Siemens.
+
+The Hermes chip implements a hardware-based system management, e.g. for
+controlling fan speed and core voltage. There is also a watchdog counter on
+the chip which can trigger an alarm and even shut the system down.
+
+The chip provides three temperature values (CPU, motherboard and
+auxiliary), three voltage values (+12V, +5V and battery) and three fans
+(power supply, CPU and auxiliary).
+
+Temperatures are measured in degrees Celsius. The resolution is 1 degree.
+
+Fan rotation speeds are reported in RPM (rotations per minute). The value
+can be divided by a programmable divider (1, 2 or 4) which is stored on
+the chip.
+
+Voltage sensors (also known as "in" sensors) report their values in volts.
+
+All values are reported as final values from the driver. There is no need
+for further calculations.
+
+
+Detailed description
+--------------------
+
+Below you'll find a single line description of all the bit values. With
+this information, you're able to decode e. g. alarms, wdog, etc. To make
+use of the watchdog, you'll need to set the watchdog time and enable the
+watchdog. After that it is necessary to restart the watchdog time within
+the specified period of time, or a system reset will occur.

+Limitations
+-----------
+
+* Measuring fan speed
+It seems that the chip counts "ripples" (typical fans produce 2 ripples per
+rotation while VERAX fans produce 18) in a 9-bit register. This register is
+read out every second, then the ripple prescaler (2, 4 or 8) is applied and
+the result is stored in the 8 bit output register. Due to the limitation of
+the counting register to 9 bits, it is impossible to measure a VERAX fan
+properly (even with a prescaler of 8). At its maximum speed of 3500 RPM the
+fan produces 1080 ripples per second which causes the counting register to
+overflow twice, leading to only 186 RPM.
+
+* Measuring input voltages
+in2 ("battery") reports the voltage of the onboard lithium battery and not
++3.3V from the power supply.
+
+* Undocumented features
+Fujitsu-Siemens Computers has not documented all features of the chip so
+far. Their software, System Guard, shows that there are a still some
+features which cannot be controlled by this implementation.

+Description
+-----------
+
+IMPORTANT:
+
+For the revision 0x00 chip, the in0, in1, and in2  values (+5V, +3V,
+and +12V) CANNOT be read. This is a limitation of the chip, not the driver.
+
+This driver supports the Genesys Logic GL518SM chip. There are at least
+two revision of this chip, which we call revision 0x00 and 0x80. Revision
+0x80 chips support the reading of all voltages and revision 0x00 only
+for VIN3.
+
+The GL518SM implements one temperature sensor, two fan rotation speed
+sensors, and four voltage sensors. It can report alarms through the
+computer speakers.
+
+Temperatures are measured in degrees Celsius. An alarm goes off while the
+temperature is above the over temperature limit, and has not yet dropped
+below the hysteresis limit. The alarm always reflects the current
+situation. Measurements are guaranteed between -10 degrees and +110
+degrees, with a accuracy of +/-3 degrees.
+
+Rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. In
+case when you have selected to turn fan1 off, no fan1 alarm is triggered.
+
+Fan readings can be divided by a programmable divider (1, 2, 4 or 8) to
+give the readings more range or accuracy.  Not all RPM values can
+accurately be represented, so some rounding is done. With a divider
+of 2, the lowest representable value is around 1900 RPM.
+
+Voltage sensors (also known as VIN sensors) report their values in volts.
+An alarm is triggered if the voltage has crossed a programmable minimum or
+maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. The VDD input
+measures voltages between 0.000 and 5.865 volt, with a resolution of 0.023
+volt. The other inputs measure voltages between 0.000 and 4.845 volt, with
+a resolution of 0.019 volt. Note that revision 0x00 chips do not support
+reading the current voltage of any input except for VIN3; limit setting and
+alarms work fine, though.
+
+When an alarm is triggered, you can be warned by a beeping signal through your
+computer speaker. It is possible to enable all beeping globally, or only the
+beeping for some alarms.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once (except for temperature alarms). This means that the
+cause for the alarm may already have disappeared! Note that in the current
+implementation, all hardware registers are read whenever any data is read
+(unless it is less than 1.5 seconds since the last update). This means that
+you can easily miss once-only alarms.
+
+The GL518SM only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.

+
+Description
+-----------
+
+This driver implements support for the IT8705F, IT8712F and SiS950 chips.
+
+This driver also supports IT8712F, which adds SMBus access, and a VID
+input, used to report the Vcore voltage of the Pentium processor.
+The IT8712F additionally features VID inputs.
+
+These chips are 'Super I/O chips', supporting floppy disks, infrared ports,
+joysticks and other miscellaneous stuff. For hardware monitoring, they
+include an 'environment controller' with 3 temperature sensors, 3 fan
+rotation speed sensors, 8 voltage sensors, and associated alarms.
+
+Temperatures are measured in degrees Celsius. An alarm is triggered once
+when the Overtemperature Shutdown limit is crossed.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give the
+readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+Voltage sensors (also known as IN sensors) report their values in volts. An
+alarm is triggered if the voltage has crossed a programmable minimum or
+maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 4.08 volts, with a resolution of
+0.016 volt. The battery voltage in8 does not have limit registers.
+
+The VID lines (IT8712F only) encode the core voltage value: the voltage
+level your processor should work with. This is hardcoded by the mainboard
+and/or processor itself. It is a value in volts.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared! Note that in the current implementation, all hardware
+registers are read whenever any data is read (unless it is less than 1.5
+seconds since the last update). This means that you can easily miss
+once-only alarms.
+
+The IT87xx only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.
+
+To change sensor N to a thermistor, 'echo 2 > tempN_type' where N is 1, 2,
+or 3. To change sensor N to a thermal diode, 'echo 3 > tempN_type'.
+Give 0 for unused sensor. Any other value is invalid. To configure this at
+startup, consult lm_sensors's /etc/sensors.conf. (2 = thermistor;
+3 = thermal diode)
+
+The fan speed control features are limited to manual PWM mode. Automatic
+"Smart Guardian" mode control handling is not implemented. However

+Kernel driver lm63
+==================
+
+Supported chips:

+    Prefix: 'lm63'
+    Addresses scanned: I2C 0x4c
+    Datasheet: Publicly available at the National Semiconductor website
+               http://www.national.com/pf/LM/LM63.html
+
+Author: Jean Delvare <khali@linux-fr.org>
+
+Thanks go to Tyan and especially Alex Buckingham for setting up a remote
+access to their S4882 test platform for this driver.
+  http://www.tyan.com/
+
+Description
+-----------
+
+The LM63 is a digital temperature sensor with integrated fan monitoring
+and control.
+
+The LM63 is basically an LM86 with fan speed monitoring and control
+capabilities added. It misses some of the LM86 features though:
+ - No low limit for local temperature.
+ - No critical limit for local temperature.
+ - Critical limit for remote temperature can be changed only once. We
+   will consider that the critical limit is read-only.
+
+The datasheet isn't very clear about what the tachometer reading is.
+
+An explanation from National Semiconductor: The two lower bits of the read
+value have to be masked out. The value is still 16 bit in width.
+
+All temperature values are given in degrees Celsius. Resolution is 1.0
+degree for the local temperature, 0.125 degree for the remote temperature.
+
+The fan speed is measured using a tachometer. Contrary to most chips which
+store the value in an 8-bit register and have a selectable clock divider
+to make sure that the result will fit in the register, the LM63 uses 16-bit
+value for measuring the speed of the fan. It can measure fan speeds down to
+83 RPM, at least in theory.
+
+Note that the pin used for fan monitoring is shared with an alert out
+function. Depending on how the board designer wanted to use the chip, fan
+speed monitoring will or will not be possible. The proper chip configuration
+is left to the BIOS, and the driver will blindly trust it.
+
+A PWM output can be used to control the speed of the fan. The LM63 has two
+PWM modes: manual and automatic. Automatic mode is not fully implemented yet
+(you cannot define your custom PWM/temperature curve), and mode change isn't
+supported either.
+
+The lm63 driver will not update its values more frequently than every
+second; reading them more often will do no harm, but will return 'old'
+values.

+Description
+-----------
+
+The LM75 implements one temperature sensor. Limits can be set through the
+Overtemperature Shutdown register and Hysteresis register. Each value can be
+set and read to half-degree accuracy.
+An alarm is issued (usually to a connected LM78) when the temperature
+gets higher then the Overtemperature Shutdown value; it stays on until
+the temperature falls below the Hysteresis value.
+All temperatures are in degrees Celsius, and are guaranteed within a
+range of -55 to +125 degrees.
+
+The LM75 only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.
+
+The LM75 is usually used in combination with LM78-like chips, to measure
+the temperature of the processor(s).
+
+The DS75, DS1775, MAX6625, and MAX6626 are supported as well.
+They are not distinguished from an LM75. While most of these chips
+have three additional bits of accuracy (12 vs. 9 for the LM75),
+the additional bits are not supported. Not only that, but these chips will
+not be detected if not in 9-bit precision mode (use the force parameter if
+needed).
+
+The TCN75 is supported as well, and is not distinguished from an LM75.
+
+The LM75 is essentially an industry standard; there may be other
+LM75 clones not listed here, with or without various enhancements,
+that are supported.
+
+The LM77 is not supported, contrary to what we pretended for a long time.
+Both chips are simply not compatible, value encoding differs.

+
+Description
+-----------
+
+This driver implements support for the National Semiconductor LM78, LM78-J
+and LM79. They are described as 'Microprocessor System Hardware Monitors'.
+
+There is almost no difference between the three supported chips. Functionally,
+the LM78 and LM78-J are exactly identical. The LM79 has one more VID line,
+which is used to report the lower voltages newer Pentium processors use.
+From here on, LM7* means either of these three types.
+
+The LM7* implements one temperature sensor, three fan rotation speed sensors,
+seven voltage sensors, VID lines, alarms, and some miscellaneous stuff.
+
+Temperatures are measured in degrees Celsius. An alarm is triggered once
+when the Overtemperature Shutdown limit is crossed; it is triggered again
+as soon as it drops below the Hysteresis value. A more useful behavior
+can be found by setting the Hysteresis value to +127 degrees Celsius; in
+this case, alarms are issued during all the time when the actual temperature
+is above the Overtemperature Shutdown value. Measurements are guaranteed
+between -55 and +125 degrees, with a resolution of 1 degree.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+Voltage sensors (also known as IN sensors) report their values in volts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 4.08 volts, with a resolution
+of 0.016 volt.
+
+The VID lines encode the core voltage value: the voltage level your processor
+should work with. This is hardcoded by the mainboard and/or processor itself.
+It is a value in volts. When it is unconnected, you will often find the
+value 3.50 V here.
+
+In addition to the alarms described above, there are a couple of additional
+ones. There is a BTI alarm, which gets triggered when an external chip has
+crossed its limits. Usually, this is connected to all LM75 chips; if at
+least one crosses its limits, this bit gets set. The CHAS alarm triggers
+if your computer case is open. The FIFO alarms should never trigger; it
+indicates an internal error. The SMI_IN alarm indicates some other chip
+has triggered an SMI interrupt. As we do not use SMI interrupts at all,
+this condition usually indicates there is a problem with some other
+device.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared! Note that in the current implementation, all
+hardware registers are read whenever any data is read (unless it is less
+than 1.5 seconds since the last update). This means that you can easily
+miss once-only alarms.
+
+The LM7* only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.

+
+This driver implements support for the National Semiconductor LM80.
+It is described as a 'Serial Interface ACPI-Compatible Microprocessor
+System Hardware Monitor'.
+
+The LM80 implements one temperature sensor, two fan rotation speed sensors,
+seven voltage sensors, alarms, and some miscellaneous stuff.
+
+Temperatures are measured in degrees Celsius. There are two sets of limits
+which operate independently. When the HOT Temperature Limit is crossed,
+this will cause an alarm that will be reasserted until the temperature
+drops below the HOT Hysteresis. The Overtemperature Shutdown (OS) limits
+should work in the same way (but this must be checked; the datasheet
+is unclear about this). Measurements are guaranteed between -55 and
++125 degrees. The current temperature measurement has a resolution of
+0.0625 degrees; the limits have a resolution of 1 degree.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+Voltage sensors (also known as IN sensors) report their values in volts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 2.55 volts, with a resolution
+of 0.01 volt.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may

+
+Description
+-----------
+
+The LM83 is a digital temperature sensor. It senses its own temperature as
+well as the temperature of up to three external diodes. It is compatible
+with many other devices such as the LM84 and all other ADM1021 clones.
+The main difference between the LM83 and the LM84 in that the later can
+only sense the temperature of one external diode.
+
+Using the adm1021 driver for a LM83 should work, but only two temperatures
+will be reported instead of four.
+
+The LM83 is only found on a handful of motherboards. Both a confirmed
+list and an unconfirmed list follow. If you can confirm or infirm the
+fact that any of these motherboards do actually have an LM83, please
+contact us. Note that the LM90 can easily be misdetected as a LM83.
+
+Confirmed motherboards:
+    SBS         P014
+
+Unconfirmed motherboards:
+    Gigabyte    GA-8IK1100
+    Iwill       MPX2
+    Soltek      SL-75DRV5
+
+The driver has been successfully tested by Magnus Forsström, who I'd
+like to thank here. More testers will be of course welcome.
+
+The fact that the LM83 is only scarcely used can be easily explained.
+Most motherboards come with more than just temperature sensors for
+health monitoring. They also have voltage and fan rotation speed
+sensors. This means that temperature-only chips are usually used as
+secondary chips coupled with another chip such as an IT8705F or similar
+chip, which provides more features. Since systems usually need three
+temperature sensors (motherboard, processor, power supply) and primary
+chips provide some temperature sensors, the secondary chip, if needed,
+won't have to handle more than two temperatures. Thus, ADM1021 clones
+are sufficient, and there is no need for a four temperatures sensor
+chip such as the LM83. The only case where using an LM83 would make
+sense is on SMP systems, such as the above-mentioned Iwill MPX2,
+because you want an additional temperature sensor for each additional
+CPU.
+
+On the SBS P014, this is different, since the LM83 is the only hardware
+monitoring chipset. One temperature sensor is used for the motherboard
+(actually measuring the LM83's own temperature), one is used for the
+CPU. The two other sensors must be used to measure the temperature of
+two other points of the motherboard. We suspect these points to be the
+north and south bridges, but this couldn't be confirmed.
+
+All temperature values are given in degrees Celsius. Local temperature
+is given within a range of 0 to +85 degrees. Remote temperatures are
+given within a range of 0 to +125 degrees. Resolution is 1.0 degree,
+accuracy is guaranteed to 3.0 degrees (see the datasheet for more
+details).
+
+Each sensor has its own high limit, but the critical limit is common to
+all four sensors. There is no hysteresis mechanism as found on most
+recent temperature sensors.
+
+The lm83 driver will not update its values more frequently than every
+other second; reading them more often will do no harm, but will return
+'old' values.

+Description
+-----------
+
+This driver implements support for the National Semiconductor LM85 and
+compatible chips including the Analog Devices ADM1027, ADT7463 and
+SMSC EMC6D10x chips family.
+
+The LM85 uses the 2-wire interface compatible with the SMBUS 2.0
+specification. Using an analog to digital converter it measures three (3)
+temperatures and five (5) voltages. It has four (4) 16-bit counters for
+measuring fan speed. Five (5) digital inputs are provided for sampling the
+VID signals from the processor to the VRM. Lastly, there are three (3) PWM
+outputs that can be used to control fan speed.
+
+The voltage inputs have internal scaling resistors so that the following
+voltage can be measured without external resistors:
+
+  2.5V, 3.3V, 5V, 12V, and CPU core voltage (2.25V)
+
+The temperatures measured are one internal diode, and two remote diodes.
+Remote 1 is generally the CPU temperature. These inputs are designed to
+measure a thermal diode like the one in a Pentium 4 processor in a socket
+423 or socket 478 package. They can also measure temperature using a
+transistor like the 2N3904.
+
+A sophisticated control system for the PWM outputs is designed into the
+LM85 that allows fan speed to be adjusted automatically based on any of the
+three temperature sensors. Each PWM output is individually adjustable and
+programmable. Once configured, the LM85 will adjust the PWM outputs in
+response to the measured temperatures without further host intervention.
+This feature can also be disabled for manual control of the PWM's.
+
+Each of the measured inputs (voltage, temperature, fan speed) has
+corresponding high/low limit values. The LM85 will signal an ALARM if any
+measured value exceeds either limit.
+
+The LM85 samples all inputs continuously. The lm85 driver will not read
+the registers more often than once a second. Further, configuration data is
+only read once each 5 minutes. There is twice as much config data as
+measurements, so this would seem to be a worthwhile optimization.
+
+Special Features
+----------------
+
+The LM85 has four fan speed monitoring modes. The ADM1027 has only two.
+Both have special circuitry to compensate for PWM interactions with the
+TACH signal from the fans. The ADM1027 can be configured to measure the
+speed of a two wire fan, but the input conditioning circuitry is different
+for 3-wire and 2-wire mode. For this reason, the 2-wire fan modes are not
+exposed to user control. The BIOS should initialize them to the correct
+mode. If you've designed your own ADM1027, you'll have to modify the
+init_client function and add an insmod parameter to set this up.
+
+To smooth the response of fans to changes in temperature, the LM85 has an
+optional filter for smoothing temperatures. The ADM1027 has the same
+config option but uses it to rate limit the changes to fan speed instead.
+
+The ADM1027 and ADT7463 have a 10-bit ADC and can therefore measure
+temperatures with 0.25 degC resolution. They also provide an offset to the
+temperature readings that is automatically applied during measurement.
+This offset can be used to zero out any errors due to traces and placement.
+The documentation says that the offset is in 0.25 degC steps, but in
+initial testing of the ADM1027 it was 1.00 degC steps. Analog Devices has
+confirmed this "bug". The ADT7463 is reported to work as described in the
+documentation. The current lm85 driver does not show the offset register.
+
+The ADT7463 has a THERM asserted counter. This counter has a 22.76ms
+resolution and a range of 5.8 seconds. The driver implements a 32-bit
+accumulator of the counter value to extend the range to over a year. The
+counter will stay at it's max value until read.
+
+See the vendor datasheets for more information. There is application note
+from National (AN-1260) with some additional information about the LM85.
+The Analog Devices datasheet is very detailed and describes a procedure for
+determining an optimal configuration for the automatic PWM control.
+
+The SMSC EMC6D100 & EMC6D101 monitor external voltages, temperatures, and
+fan speeds. They use this monitoring capability to alert the system to out
+of limit conditions and can automatically control the speeds of multiple
+fans in a PC or embedded system. The EMC6D101, available in a 24-pin SSOP
+package, and the EMC6D100, available in a 28-pin SSOP package, are designed
+to be register compatible. The EMC6D100 offers all the features of the
+EMC6D101 plus additional voltage monitoring and system control features.
+Unfortunately it is not possible to distinguish between the package
+versions on register level so these additional voltage inputs may read
+zero. The EMC6D102 features addtional ADC bits thus extending precision
+of voltage and temperature channels.
+
+
+Hardware Configurations
+-----------------------
+
+The LM85 can be jumpered for 3 different SMBus addresses. There are
+no other hardware configuration options for the LM85.
+
+The lm85 driver detects both LM85B and LM85C revisions of the chip. See the
+datasheet for a complete description of the differences. Other than
+identifying the chip, the driver behaves no differently with regard to
+these two chips. The LM85B is recommended for new designs.
+
+The ADM1027 and ADT7463 chips have an optional SMBALERT output that can be
+used to signal the chipset in case a limit is exceeded or the temperature
+sensors fail. Individual sensor interrupts can be masked so they won't
+trigger SMBALERT. The SMBALERT output if configured replaces one of the other
+functions (PWM2 or IN0). This functionality is not implemented in current
+driver.
+
+The ADT7463 also has an optional THERM output/input which can be connected
+to the processor PROC_HOT output. If available, the autofan control
+dynamic Tmin feature can be enabled to keep the system temperature within
+spec (just?!) with the least possible fan noise.
+
+Configuration Notes
+-------------------
+
+Besides standard interfaces driver adds following:
+
+* Temperatures and Zones
+
+Each temperature sensor is associated with a Zone. There are three
+sensors and therefore three zones (# 1, 2 and 3). Each zone has the following
+temperature configuration points:
+
+* temp#_auto_temp_off - temperature below which fans should be off or spinning very low.
+* temp#_auto_temp_min - temperature over which fans start to spin.
+* temp#_auto_temp_max - temperature when fans spin at full speed.
+* temp#_auto_temp_crit - temperature when all fans will run full speed.
+
+* PWM Control
+
+There are three PWM outputs. The LM85 datasheet suggests that the
+pwm3 output control both fan3 and fan4. Each PWM can be individually
+configured and assigned to a zone for it's control value. Each PWM can be
+configured individually according to the following options.
+
+* pwm#_auto_pwm_min - this specifies the PWM value for temp#_auto_temp_off
+                      temperature. (PWM value from 0 to 255)
+
+* pwm#_auto_pwm_freq - select base frequency of PWM output. You can select
+                       in range of 10.0 to 94.0 Hz in .1 Hz units.
+		       (Values 100 to 940).
+
+The pwm#_auto_pwm_freq can be set to one of the following 8 values. Setting the
+frequency to a value not on this list, will result in the next higher frequency
+being selected. The actual device frequency may vary slightly from this
+specification as designed by the manufacturer. Consult the datasheet for more
+details. (PWM Frequency values:  100, 150, 230, 300, 380, 470, 620, 940)
+
+* pwm#_auto_pwm_minctl - this flags selects for temp#_auto_temp_off temperature
+                         the bahaviour of fans. Write 1 to let fans spinning at
+			 pwm#_auto_pwm_min or write 0 to let them off.
+
+NOTE: It has been reported that there is a bug in the LM85 that causes the flag
+to be associated with the zones not the PWMs. This contradicts all the
+published documentation. Setting pwm#_min_ctl in this case actually affects all
+PWMs controlled by zone '#'.
+
+* PWM Controlling Zone selection
+
+* pwm#_auto_channels - controls zone that is associated with PWM
+
+Configuration choices:
+
+   Value     Meaning
+  ------  ------------------------------------------------
+      1    Controlled by Zone 1
+      2    Controlled by Zone 2
+      3    Controlled by Zone 3
+     23    Controlled by higher temp of Zone 2 or 3
+    123    Controlled by highest temp of Zone 1, 2 or 3
+      0    PWM always 0%  (off)
+     -1    PWM always 100%  (full on)
+     -2    Manual control (write to 'pwm#' to set)
+
+The National LM85's have two vendor specific configuration
+features. Tach. mode and Spinup Control. For more details on these,
+see the LM85 datasheet or Application Note AN-1260.
+
+The Analog Devices ADM1027 has several vendor specific enhancements.
+The number of pulses-per-rev of the fans can be set, Tach monitoring
+can be optimized for PWM operation, and an offset can be applied to
+the temperatures to compensate for systemic errors in the
+measurements.
+
+In addition to the ADM1027 features, the ADT7463 also has Tmin control
+and THERM asserted counts. Automatic Tmin control acts to adjust the
+Tmin value to maintain the measured temperature sensor at a specified
+temperature. There isn't much documentation on this feature in the
+ADT7463 data sheet. This is not supported by current driver.

+
+Description
+-----------
+
+This driver implements support for the National Semiconductor LM87.
+
+The LM87 implements up to three temperature sensors, up to two fan
+rotation speed sensors, up to seven voltage sensors, alarms, and some
+miscellaneous stuff.
+
+Temperatures are measured in degrees Celsius. Each input has a high
+and low alarm settings. A high limit produces an alarm when the value
+goes above it, and an alarm is also produced when the value goes below
+the low limit.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+Voltage sensors (also known as IN sensors) report their values in
+volts. An alarm is triggered if the voltage has crossed a programmable
+minimum or maximum limit. Note that minimum in this case always means
+'closest to zero'; this is important for negative voltage measurements.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared! Note that in the current implementation, all
+hardware registers are read whenever any data is read (unless it is less
+than 1.0 seconds since the last update). This means that you can easily
+miss once-only alarms.
+
+The lm87 driver only updates its values each 1.0 seconds; reading it more
+often will do no harm, but will return 'old' values.
+
+
+Hardware Configurations
+-----------------------
+
+The LM87 has four pins which can serve one of two possible functions,
+depending on the hardware configuration.
+
+Some functions share pins, so not all functions are available at the same
+time. Which are depends on the hardware setup. This driver assumes that
+the BIOS configured the chip correctly. In that respect, it differs from
+the original driver (from lm_sensors for Linux 2.4), which would force the
+LM87 to an arbitrary, compile-time chosen mode, regardless of the actual
+chipset wiring.
+
+For reference, here is the list of exclusive functions:
+ - in0+in5 (default) or temp3
+ - fan1 (default) or in6
+ - fan2 (default) or in7
+ - VID lines (default) or IRQ lines (not handled by this driver)

+Description
+-----------
+
+The LM90 is a digital temperature sensor. It senses its own temperature as
+well as the temperature of up to one external diode. It is compatible
+with many other devices such as the LM86, the LM89, the LM99, the ADM1032,
+the MAX6657, MAX6658 and the MAX6659 all of which are supported by this driver.
+Note that there is no easy way to differentiate between the last three
+variants. The extra address and features of the MAX6659 are not supported by
+this driver. Additionally, the ADT7461 is supported if found in ADM1032
+compatibility mode.
+
+The specificity of this family of chipsets over the ADM1021/LM84
+family is that it features critical limits with hysteresis, and an
+increased resolution of the remote temperature measurement.
+
+The different chipsets of the family are not strictly identical, although
+very similar. This driver doesn't handle any specific feature for now,
+but could if there ever was a need for it. For reference, here comes a
+non-exhaustive list of specific features:
+
+LM90:
+  * Filter and alert configuration register at 0xBF.
+  * ALERT is triggered by temperatures over critical limits.
+
+LM86 and LM89:
+  * Same as LM90
+  * Better external channel accuracy
+
+LM99:
+  * Same as LM89
+  * External temperature shifted by 16 degrees down
+
+ADM1032:
+  * Consecutive alert register at 0x22.
+  * Conversion averaging.
+  * Up to 64 conversions/s.
+  * ALERT is triggered by open remote sensor.
+
+ADT7461
+  * Extended temperature range (breaks compatibility)
+  * Lower resolution for remote temperature
+
+MAX6657 and MAX6658:
+  * Remote sensor type selection
+
+MAX6659
+  * Selectable address
+  * Second critical temperature limit
+  * Remote sensor type selection
+
+All temperature values are given in degrees Celsius. Resolution
+is 1.0 degree for the local temperature, 0.125 degree for the remote
+temperature.
+
+Each sensor has its own high and low limits, plus a critical limit.
+Additionally, there is a relative hysteresis value common to both critical
+values. To make life easier to user-space applications, two absolute values
+are exported, one for each channel, but these values are of course linked.
+Only the local hysteresis can be set from user-space, and the same delta
+applies to the remote hysteresis.
+
+The lm90 driver will not update its values more frequently than every
+other second; reading them more often will do no harm, but will return
+'old' values.

+This driver implements support for the National Semiconductor LM92
+temperature sensor.
+
+Each LM92 temperature sensor supports a single temperature sensor. There are
+alarms for high, low, and critical thresholds. There's also an hysteresis to
+control the thresholds for resetting alarms.
+
+Support was added later for the LM76 and Maxim MAX6633/MAX6634/MAX6635,
+which are mostly compatible. They have not all been tested, so you
+may need to use the force parameter.

+
+All temperature values are given in degrees Celsius. Resolution
+is 1.0 degree for the local temperature and for the remote temperature.
+
+Only the external sensor has high and low limits.
+
+The max1619 driver will not update its values more frequently than every

+
+Description
+-----------
+
+The National Semiconductor PC87360 Super I/O chip contains monitoring and
+PWM control circuitry for two fans. The PC87363 chip is similar, and the
+PC87364 chip has monitoring and PWM control for a third fan.
+
+The National Semiconductor PC87365 and PC87366 Super I/O chips are complete
+hardware monitoring chipsets, not only controlling and monitoring three fans,
+but also monitoring eleven voltage inputs and two (PC87365) or up to four
+(PC87366) temperatures.

+
+The driver assumes that no more than one chip is present, and one of the
+standard Super I/O addresses is used (0x2E/0x2F or 0x4E/0x4F)
+
+Fan Monitoring
+--------------
+
+Fan rotation speeds are reported in RPM (revolutions per minute). An alarm
+is triggered if the rotation speed has dropped below a programmable limit.
+A different alarm is triggered if the fan speed is too low to be measured.
+
+Fan readings are affected by a programmable clock divider, giving the
+readings more range or accuracy. Usually, users have to learn how it works,
+but this driver implements dynamic clock divider selection, so you don't
+have to care no more.
+
+For reference, here are a few values about clock dividers:
+
+                slowest         accuracy        highest
+                measurable      around 3000     accurate
+    divider     speed (RPM)     RPM (RPM)       speed (RPM)
+         1        1882              18           6928
+         2         941              37           4898
+         4         470              74           3464
+         8         235             150           2449
+
+For the curious, here is how the values above were computed:
+ * slowest measurable speed: clock/(255*divider)
+ * accuracy around 3000 RPM: 3000^2/clock
+ * highest accurate speed: sqrt(clock*100)
+The clock speed for the PC87360 family is 480 kHz. I arbitrarily chose 100
+RPM as the lowest acceptable accuracy.
+
+As mentioned above, you don't have to care about this no more.
+
+Note that not all RPM values can be represented, even when the best clock
+divider is selected. This is not only true for the measured speeds, but
+also for the programmable low limits, so don't be surprised if you try to
+set, say, fan1_min to 2900 and it finally reads 2909.
+
+
+Fan Control
+-----------
+
+PWM (pulse width modulation) values range from 0 to 255, with 0 meaning
+that the fan is stopped, and 255 meaning that the fan goes at full speed.
+
+Be extremely careful when changing PWM values. Low PWM values, even
+non-zero, can stop the fan, which may cause irreversible damage to your
+hardware if temperature increases too much. When changing PWM values, go
+step by step and keep an eye on temperatures.
+
+One user reported problems with PWM. Changing PWM values would break fan
+speed readings. No explanation nor fix could be found.
+
+
+Temperature Monitoring
+----------------------
+
+Temperatures are reported in degrees Celsius. Each temperature measured has
+associated low, high and overtemperature limits, each of which triggers an
+alarm when crossed.
+
+The first two temperature channels are external. The third one (PC87366
+only) is internal.
+
+The PC87366 has three additional temperature channels, based on
+thermistors (as opposed to thermal diodes for the first three temperature
+channels). For technical reasons, these channels are held by the VLM
+(voltage level monitor) logical device, not the TMS (temperature
+measurement) one. As a consequence, these temperatures are exported as
+voltages, and converted into temperatures in user-space.
+
+Note that these three additional channels share their pins with the
+external thermal diode channels, so you (physically) can't use them all at
+the same time. Although it should be possible to mix the two sensor types,
+the documents from National Semiconductor suggest that motherboard
+manufacturers should choose one type and stick to it. So you will more
+likely have either channels 1 to 3 (thermal diodes) or 3 to 6 (internal
+thermal diode, and thermistors).
+
+
+Voltage Monitoring
+------------------
+
+Voltages are reported relatively to a reference voltage, either internal or
+external. Some of them (in7:Vsb, in8:Vdd and in10:AVdd) are divided by two
+internally, you will have to compensate in sensors.conf. Others (in0 to in6)
+are likely to be divided externally. The meaning of each of these inputs as
+well as the values of the resistors used for division is left to the
+motherboard manufacturers, so you will have to document yourself and edit
+sensors.conf accordingly. National Semiconductor has a document with
+recommended resistor values for some voltages, but this still leaves much
+room for per motherboard specificities, unfortunately. Even worse,
+motherboard manufacturers don't seem to care about National Semiconductor's
+recommendations.
+
+Each voltage measured has associated low and high limits, each of which
+triggers an alarm when crossed.
+
+When available, VID inputs are used to provide the nominal CPU Core voltage.
+The driver will default to VRM 9.0, but this can be changed from user-space.
+The chipsets can handle two sets of VID inputs (on dual-CPU systems), but
+the driver will only export one for now. This may change later if there is
+a need.
+
+
+General Remarks
+---------------
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared! Note that all hardware registers are read whenever any
+data is read (unless it is less than 2 seconds since the last update, in
+which case cached values are returned instead). As a consequence, when
+a once-only alarm triggers, it may take 2 seconds for it to show, and 2
+more seconds for it to disappear.
+
+Monitoring of in9 isn't enabled at lower init levels (<3) because that
+channel measures the battery voltage (Vbat). It is a known fact that
+repeatedly sampling the battery voltage reduces its lifetime. National
+Semiconductor smartly designed their chipset so that in9 is sampled only
+once every 1024 sampling cycles (that is every 34 minutes at the default
+sampling rate), so the effect is attenuated, but still present.
+
+
+Limitations
+-----------
+
+The datasheets suggests that some values (fan mins, fan dividers)
+shouldn't be changed once the monitoring has started, but we ignore that
+recommendation. We'll reconsider if it actually causes trouble.

+Description
+-----------
+
+The SiS5595 southbridge has integrated hardware monitor functions. It also
+has an I2C bus, but this driver only supports the hardware monitor. For the
+I2C bus driver see i2c-sis5595.
+
+The SiS5595 implements zero or one temperature sensor, two fan speed
+sensors, four or five voltage sensors, and alarms.
+
+On the first version of the chip, there are four voltage sensors and one
+temperature sensor.
+
+On the second version of the chip, the temperature sensor (temp) and the
+fifth voltage sensor (in4) share a pin which is configurable, but not
+through the driver. Sorry. The driver senses the configuration of the pin,
+which was hopefully set by the BIOS.
+
+Temperatures are measured in degrees Celsius. An alarm is triggered once
+when the max is crossed; it is also triggered when it drops below the min
+value. Measurements are guaranteed between -55 and +125 degrees, with a
+resolution of 1 degree.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+Voltage sensors (also known as IN sensors) report their values in volts. An
+alarm is triggered if the voltage has crossed a programmable minimum or
+maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 4.08 volts, with a resolution of
+0.016 volt.
+
+In addition to the alarms described above, there is a BTI alarm, which gets
+triggered when an external chip has crossed its limits. Usually, this is
+connected to some LM75-like chip; if at least one crosses its limits, this
+bit gets set.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared! Note that in the current implementation, all hardware
+registers are read whenever any data is read (unless it is less than 1.5
+seconds since the last update). This means that you can easily miss
+once-only alarms.
+
+The SiS5595 only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.
+
+Problems
+--------
+Some chips refuse to be enabled. We don't know why.
+The driver will recognize this and print a message in dmesg.

+
+Methods for detecting the HP SIO and reading the thermal data on a dc7100.
+
+The thermal information on the dc7100 is contained in the SIO Hardware Monitor
+(HWM). The information is accessed through an index/data pair. The index/data
+pair is located at the HWM Base Address + 0 and the HWM Base Address + 1. The
+HWM Base address can be obtained from Logical Device 8, registers 0x60 (MSB)
+and 0x61 (LSB). Currently we are using 0x480 for the HWM Base Address and
+0x480 and 0x481 for the index/data pair.
+
+Reading temperature information.
+The temperature information is located in the following registers:
+Temp1		0x25	(Currently, this reflects the CPU temp on all systems).
+Temp2		0x26
+Temp3		0x27
+Temp4		0x80
+
+Programming Example
+The following is an example of how to read the HWM temperature registers:
+MOV	DX,480H
+MOV	AX,25H
+OUT	DX,AL
+MOV	DX,481H
+IN	AL,DX
+
+AL contains the data in hex, the temperature in Celsius is the decimal
+equivalent.
+
+Ex: If AL contains 0x2A, the temperature is 42 degrees C.
+
+Reading tach information.
+The fan speed information is located in the following registers:
+		LSB	MSB
+Tach1		0x28	0x29	(Currently, this reflects the CPU
+				fan speed on all systems).
+Tach2		0x2A	0x2B
+Tach3		0x2C	0x2D
+Tach4		0x2E	0x2F
+
+Important!!!
+Reading the tach LSB locks the tach MSB.
+The LSB Must be read first.
+
+How to convert the tach reading to RPM.
+The tach reading (TCount) is given by: (Tach MSB * 256) + (Tach LSB)
+The SIO counts the number of 90kHz (11.111us) pulses per revolution.
+RPM = 60/(TCount * 11.111us)
+
+Example:
+Reg 0x28 = 0x9B
+Reg 0x29 = 0x08
+
+TCount = 0x89B = 2203
+
+RPM = 60 / (2203 * 11.11111 E-6) = 2451 RPM
+
+Obtaining the SIO version.
+
+CONFIGURATION SEQUENCE
+To program the configuration registers, the following sequence must be followed:
+1. Enter Configuration Mode
+2. Configure the Configuration Registers
+3. Exit Configuration Mode.
+
+Enter Configuration Mode
+To place the chip into the Configuration State The config key (0x55) is written
+to the CONFIG PORT (0x2E).
+
+Configuration Mode
+In configuration mode, the INDEX PORT is located at the CONFIG PORT address and
+the DATA PORT is at INDEX PORT address + 1.
+
+The desired configuration registers are accessed in two steps:
+a.	Write the index of the Logical Device Number Configuration Register
+	(i.e., 0x07) to the INDEX PORT and then write the number of the
+	desired logical device to the DATA PORT.
+
+b.	Write the address of the desired configuration register within the
+	logical device to the INDEX PORT and then write or read the config-
+	uration register through the DATA PORT.
+
+Note: If accessing the Global Configuration Registers, step (a) is not required.
+
+Exit Configuration Mode
+To exit the Configuration State the write 0xAA to the CONFIG PORT (0x2E).
+The chip returns to the RUN State.  (This is important).
+
+Programming Example
+The following is an example of how to read the SIO Device ID located at 0x20
+
+; ENTER CONFIGURATION MODE
+MOV	DX,02EH
+MOV	AX,055H
+OUT	DX,AL
+; GLOBAL CONFIGURATION  REGISTER
+MOV	DX,02EH
+MOV	AL,20H
+OUT	DX,AL
+; READ THE DATA
+MOV	DX,02FH
+IN	AL,DX
+; EXIT CONFIGURATION MODE
+MOV	DX,02EH
+MOV	AX,0AAH
+OUT	DX,AL
+
+The registers of interest for identifying the SIO on the dc7100 are Device ID
+(0x20) and Device Rev  (0x21).
+
+The Device ID will read 0X6F
+The Device Rev currently reads 0x01
+
+Obtaining the HWM Base Address.
+The following is an example of how to read the HWM Base Address located in
+Logical Device 8.
+
+; ENTER CONFIGURATION MODE
+MOV	DX,02EH
+MOV	AX,055H
+OUT	DX,AL

+Description
+-----------
+
+The Standard Microsystems Corporation (SMSC) 47M1xx Super I/O chips
+contain monitoring and PWM control circuitry for two fans.
+
+The 47M15x and 47M192 chips contain a full 'hardware monitoring block'
+in addition to the fan monitoring and control. The hardware monitoring
+block is not supported by the driver.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+PWM values are from 0 to 255.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared! Note that in the current implementation, all
+hardware registers are read whenever any data is read (unless it is less
+than 1.5 seconds since the last update). This means that you can easily
+miss once-only alarms.

+Naming and data format standards for sysfs files
+------------------------------------------------
+
+The libsensors library offers an interface to the raw sensors data
+through the sysfs interface. See libsensors documentation and source for
+more further information. As of writing this document, libsensors
+(from lm_sensors 2.8.3) is heavily chip-dependant. Adding or updating
+support for any given chip requires modifying the library's code.
+This is because libsensors was written for the procfs interface
+older kernel modules were using, which wasn't standardized enough.
+Recent versions of libsensors (from lm_sensors 2.8.2 and later) have
+support for the sysfs interface, though.
+
+The new sysfs interface was designed to be as chip-independant as
+possible.
+
+Note that motherboards vary widely in the connections to sensor chips.
+There is no standard that ensures, for example, that the second
+temperature sensor is connected to the CPU, or that the second fan is on
+the CPU. Also, some values reported by the chips need some computation
+before they make full sense. For example, most chips can only measure
+voltages between 0 and +4V. Other voltages are scaled back into that
+range using external resistors. Since the values of these resistors
+can change from motherboard to motherboard, the conversions cannot be
+hard coded into the driver and have to be done in user space.
+
+For this reason, even if we aim at a chip-independant libsensors, it will
+still require a configuration file (e.g. /etc/sensors.conf) for proper
+values conversion, labeling of inputs and hiding of unused inputs.
+
+An alternative method that some programs use is to access the sysfs
+files directly. This document briefly describes the standards that the
+drivers follow, so that an application program can scan for entries and
+access this data in a simple and consistent way. That said, such programs
+will have to implement conversion, labeling and hiding of inputs. For
+this reason, it is still not recommended to bypass the library.
+
+If you are developing a userspace application please send us feedback on
+this standard.
+
+Note that this standard isn't completely established yet, so it is subject
+to changes, even important ones. One more reason to use the library instead
+of accessing sysfs files directly.
+
+Each chip gets its own directory in the sysfs /sys/devices tree.  To
+find all sensor chips, it is easier to follow the symlinks from
+/sys/i2c/devices/
+
+All sysfs values are fixed point numbers.  To get the true value of some
+of the values, you should divide by the specified value.
+
+There is only one value per file, unlike the older /proc specification.
+The common scheme for files naming is: <type><number>_<item>. Usual
+types for sensor chips are "in" (voltage), "temp" (temperature) and
+"fan" (fan). Usual items are "input" (measured value), "max" (high
+threshold, "min" (low threshold). Numbering usually starts from 1,
+except for voltages which start from 0 (because most data sheets use
+this). A number is always used for elements that can be present more
+than once, even if there is a single element of the given type on the
+specific chip. Other files do not refer to a specific element, so
+they have a simple name, and no number.
+
+Alarms are direct indications read from the chips. The drivers do NOT
+make comparisons of readings to thresholds. This allows violations
+between readings to be caught and alarmed. The exact definition of an
+alarm (for example, whether a threshold must be met or must be exceeded
+to cause an alarm) is chip-dependent.

+Introduction
+------------
+
+Most mainboards have sensor chips to monitor system health (like temperatures,
+voltages, fans speed). They are often connected through an I2C bus, but some
+are also connected directly through the ISA bus.
+
+The kernel drivers make the data from the sensor chips available in the /sys
+virtual filesystem. Userspace tools are then used to display or set or the
+data in a more friendly manner.
+
+Lm-sensors
+----------
+
+Core set of utilites that will allow you to obtain health information,
+setup monitoring limits etc. You can get them on their homepage
+http://www.lm-sensors.nu/ or as a package from your Linux distribution.
+
+If from website:
+Get lmsensors from project web site. Please note, you need only userspace
+part, so compile with "make user_install" target.
+
+General hints to get things working:
+
+0) get lm-sensors userspace utils
+1) compile all drivers in I2C section as modules in your kernel
+2) run sensors-detect script, it will tell you what modules you need to load.
+3) load them and run "sensors" command, you should see some results.
+4) fix sensors.conf, labels, limits, fan divisors
+5) if any more problems consult FAQ, or documentation
+
+Other utilites
+--------------
+
+If you want some graphical indicators of system health look for applications
+like: gkrellm, ksensors, xsensors, wmtemp, wmsensors, wmgtemp, ksysguardd,
+hardware-monitor
+
+If you are server administrator you can try snmpd or mrtgutils.

+
+Description
+-----------
+
+The driver does not distinguish between the chips and reports
+all as a 686A.
+
+The Via 686a southbridge has integrated hardware monitor functionality.
+It also has an I2C bus, but this driver only supports the hardware monitor.
+For the I2C bus driver, see <file:Documentation/i2c/busses/i2c-viapro>
+
+The Via 686a implements three temperature sensors, two fan rotation speed
+sensors, five voltage sensors and alarms.
+
+Temperatures are measured in degrees Celsius. An alarm is triggered once
+when the Overtemperature Shutdown limit is crossed; it is triggered again
+as soon as it drops below the hysteresis value.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+Voltage sensors (also known as IN sensors) report their values in volts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit. Voltages are internally scalled, so each voltage channel
+has a different resolution and range.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared! Note that in the current implementation, all
+hardware registers are read whenever any data is read (unless it is less
+than 1.5 seconds since the last update). This means that you can easily
+miss once-only alarms.
+
+The driver only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.

+Description
+-----------
+
+This driver implements support for ISA accesses *only* for
+the Winbond W83627HF, W83627THF, W83697HF and W83637HF Super I/O chips.
+We will refer to them collectively as Winbond chips.
+
+This driver supports ISA accesses, which should be more reliable
+than i2c accesses. Also, for Tyan boards which contain both a
+Super I/O chip and a second i2c-only Winbond chip (often a W83782D),
+using this driver will avoid i2c address conflicts and complex
+initialization that were required in the w83781d driver.
+
+If you really want i2c accesses for these Super I/O chips,
+use the w83781d driver. However this is not the preferred method
+now that this ISA driver has been developed.
+
+Technically, the w83627thf does not support a VID reading. However, it's
+possible or even likely that your mainboard maker has routed these signals
+to a specific set of general purpose IO pins (the Asus P4C800-E is one such
+board). The w83627thf driver now interprets these as VID. If the VID on
+your board doesn't work, first see doc/vid in the lm_sensors package. If
+that still doesn't help, email us at lm-sensors@lm-sensors.org.
+
+For further information on this driver see the w83781d driver
+documentation.

+
+Detection of these chips can sometimes be foiled because they can be in
+an internal state that allows no clean access. If you know the address
+of the chip, use a 'force' parameter; this will put them into a more
+well-behaved state first.
+
+The W8378* implements temperature sensors (three on the W83781D and W83782D,
+two on the W83783S), three fan rotation speed sensors, voltage sensors
+(seven on the W83781D, nine on the W83782D and six on the W83783S), VID
+lines, alarms with beep warnings, and some miscellaneous stuff.
+
+Temperatures are measured in degrees Celsius. There is always one main
+temperature sensor, and one (W83783S) or two (W83781D and W83782D) other
+sensors. An alarm is triggered for the main sensor once when the
+Overtemperature Shutdown limit is crossed; it is triggered again as soon as
+it drops below the Hysteresis value. A more useful behavior
+can be found by setting the Hysteresis value to +127 degrees Celsius; in
+this case, alarms are issued during all the time when the actual temperature
+is above the Overtemperature Shutdown value. The driver sets the
+hysteresis value for temp1 to 127 at initialization.
+
+For the other temperature sensor(s), an alarm is triggered when the
+temperature gets higher then the Overtemperature Shutdown value; it stays
+on until the temperature falls below the Hysteresis value. But on the
+W83781D, there is only one alarm that functions for both other sensors!
+Temperatures are guaranteed within a range of -55 to +125 degrees. The
+main temperature sensors has a resolution of 1 degree; the other sensor(s)
+of 0.5 degree.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8 for the
+W83781D; 1, 2, 4, 8, 16, 32, 64 or 128 for the others) to give
+the readings more range or accuracy. Not all RPM values can accurately
+be represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+
+Voltage sensors (also known as IN sensors) report their values in volts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 4.08 volts, with a resolution
+of 0.016 volt.
+
+The VID lines encode the core voltage value: the voltage level your processor
+should work with. This is hardcoded by the mainboard and/or processor itself.
+It is a value in volts. When it is unconnected, you will often find the
+value 3.50 V here.
+
+The W83782D and W83783S temperature conversion machine understands about
+several kinds of temperature probes. You can program the so-called
+beta value in the sensor files. '1' is the PII/Celeron diode, '2' is the
+TN3904 transistor, and 3435 the default thermistor value. Other values
+are (not yet) supported.
+
+In addition to the alarms described above, there is a CHAS alarm on the
+chips which triggers if your computer case is open.
+
+When an alarm goes off, you can be warned by a beeping signal through
+your computer speaker. It is possible to enable all beeping globally,
+or only the beeping for some alarms.
+
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared! Note that in the current implementation, all
+hardware registers are read whenever any data is read (unless it is less
+than 1.5 seconds since the last update). This means that you can easily
+miss once-only alarms.
+
+The chips only update values each 1.5 seconds; reading them more often
+will do no harm, but will return 'old' values.
+
+AS99127F PROBLEMS
+-----------------
+The as99127f support was developed without the benefit of a datasheet.
+In most cases it is treated as a w83781d (although revision 2 of the
+AS99127F looks more like a w83782d).
+This support will be BETA until a datasheet is released.
+One user has reported problems with fans stopping
+occasionally.
+
+Note that the individual beep bits are inverted from the other chips.
+The driver now takes care of this so that user-space applications
+don't have to know about it.
+
+Known problems:
+	- Problems with diode/thermistor settings (supported?)
+	- One user reports fans stopping under high server load.
+	- Revision 2 seems to have 2 PWM registers but we don't know
+	  how to handle them. More details below.
+
+These will not be fixed unless we get a datasheet.
+If you have problems, please lobby Asus to release a datasheet.
+Unfortunately several others have without success.
+Please do not send mail to us asking for better as99127f support.
+We have done the best we can without a datasheet.
+Please do not send mail to the author or the sensors group asking for
+a datasheet or ideas on how to convince Asus. We can't help.
+
+
+NOTES:
+-----
+  783s has no in1 so that in[2-6] are compatible with the 781d/782d.
+
+  783s pin is programmable for -5V or temp1; defaults to -5V,
+       no control in driver so temp1 doesn't work.
+
+  782d and 783s datasheets differ on which is pwm1 and which is pwm2.
+       We chose to follow 782d.
+
+  782d and 783s pin is programmable for fan3 input or pwm2 output;
+       defaults to fan3 input.
+       If pwm2 is enabled (with echo 255 1 > pwm2), then
+       fan3 will report 0.
+
+  782d has pwm1-2 for ISA, pwm1-4 for i2c. (pwm3-4 share pins with
+       the ISA pins)

+Asus Clones
+-----------
+
+We have no datasheets for the Asus clones (AS99127F and ASB100 Bach).
+Here are some very useful information that were given to us by Alex Van
+Kaam about how to detect these chips, and how to read their values. He
+also gives advice for another Asus chipset, the Mozart-2 (which we
+don't support yet). Thanks Alex!
+I reworded some parts and added personal comments.
+
+# Detection:
+
+AS99127F rev.1, AS99127F rev.2 and ASB100:
+- I2C address range: 0x29 - 0x2F
+- If register 0x58 holds 0x31 then we have an Asus (either ASB100 or
+  AS99127F)
+- Which one depends on register 0x4F (manufacturer ID):
+  0x06 or 0x94: ASB100
+  0x12 or 0xC3: AS99127F rev.1
+  0x5C or 0xA3: AS99127F rev.2
+  Note that 0x5CA3 is Winbond's ID (WEC), which let us think Asus get their
+  AS99127F rev.2 direct from Winbond. The other codes mean ATT and DVC,
+  respectively. ATT could stand for Asustek something (although it would be
+  very badly chosen IMHO), I don't know what DVC could stand for. Maybe
+  these codes simply aren't meant to be decoded that way.
+
+Mozart-2:
+- I2C address: 0x77
+- If register 0x58 holds 0x56 or 0x10 then we have a Mozart-2
+- Of the Mozart there are 3 types:
+  0x58=0x56, 0x4E=0x94, 0x4F=0x36: Asus ASM58 Mozart-2
+  0x58=0x56, 0x4E=0x94, 0x4F=0x06: Asus AS2K129R Mozart-2
+  0x58=0x10, 0x4E=0x5C, 0x4F=0xA3: Asus ??? Mozart-2
+  You can handle all 3 the exact same way :)
+
+# Temperature sensors:
+
+ASB100:
+- sensor 1: register 0x27
+- sensor 2 & 3 are the 2 LM75's on the SMBus
+- sensor 4: register 0x17
+Remark: I noticed that on Intel boards sensor 2 is used for the CPU
+  and 4 is ignored/stuck, on AMD boards sensor 4 is the CPU and sensor 2 is
+  either ignored or a socket temperature.
+
+AS99127F (rev.1 and 2 alike):
+- sensor 1: register 0x27
+- sensor 2 & 3 are the 2 LM75's on the SMBus
+Remark: Register 0x5b is suspected to be temperature type selector. Bit 1
+  would control temp1, bit 3 temp2 and bit 5 temp3.
+
+Mozart-2:
+- sensor 1: register 0x27
+- sensor 2: register 0x13
+
+# Fan sensors:
+
+ASB100, AS99127F (rev.1 and 2 alike):
+- 3 fans, identical to the W83781D
+
+Mozart-2:
+- 2 fans only, 1350000/RPM/div
+- fan 1: register 0x28,  divisor on register 0xA1 (bits 4-5)
+- fan 2: register 0x29,  divisor on register 0xA1 (bits 6-7)
+
+# Voltages:
+
+This is where there is a difference between AS99127F rev.1 and 2.
+Remark: The difference is similar to the difference between
+  W83781D and W83782D.
+
+ASB100:
+in0=r(0x20)*0.016
+in1=r(0x21)*0.016
+in2=r(0x22)*0.016
+in3=r(0x23)*0.016*1.68

+in5=r(0x25)*(-0.016)*3.97
+in6=r(0x26)*(-0.016)*1.666
+

+
+# PWM
+
+Additional info about PWM on the AS99127F (may apply to other Asus
+chips as well) by Jean Delvare as of 2004-04-09:
+
+AS99127F revision 2 seems to have two PWM registers at 0x59 and 0x5A,
+and a temperature sensor type selector at 0x5B (which basically means
+that they swapped registers 0x59 and 0x5B when you compare with Winbond
+chips).
+Revision 1 of the chip also has the temperature sensor type selector at
+0x5B, but PWM registers have no effect.
+
+We don't know exactly how the temperature sensor type selection works.
+Looks like bits 1-0 are for temp1, bits 3-2 for temp2 and bits 5-4 for
+temp3, although it is possible that only the most significant bit matters
+each time. So far, values other than 0 always broke the readings.
+
+PWM registers seem to be split in two parts: bit 7 is a mode selector,
+while the other bits seem to define a value or threshold.
+
+When bit 7 is clear, bits 6-0 seem to hold a threshold value. If the value
+is below a given limit, the fan runs at low speed. If the value is above
+the limit, the fan runs at full speed. We have no clue as to what the limit
+represents. Note that there seem to be some inertia in this mode, speed
+changes may need some time to trigger. Also, an hysteresis mechanism is
+suspected since walking through all the values increasingly and then
+decreasingly led to slightly different limits.
+
+When bit 7 is set, bits 3-0 seem to hold a threshold value, while bits 6-4
+would not be significant. If the value is below a given limit, the fan runs
+at full speed, while if it is above the limit it runs at low speed (so this
+is the contrary of the other mode, in a way). Here again, we don't know
+what the limit is supposed to represent.
+
+One remarkable thing is that the fans would only have two or three
+different speeds (transitional states left apart), not a whole range as
+you usually get with PWM.
+
+As a conclusion, you can write 0x00 or 0x8F to the PWM registers to make
+fans run at low speed, and 0x7F or 0x80 to make them run at full speed.
+
+Please contact us if you can figure out how it is supposed to work. As
+long as we don't know more, the w83781d driver doesn't handle PWM on
+AS99127F chips at all.
+
+Additional info about PWM on the AS99127F rev.1 by Hector Martin:
+
+I've been fiddling around with the (in)famous 0x59 register and
+found out the following values do work as a form of coarse pwm:
+
+0x80 - seems to turn fans off after some time(1-2 minutes)... might be
+some form of auto-fan-control based on temp? hmm (Qfan? this mobo is an
+old ASUS, it isn't marketed as Qfan. Maybe some beta pre-attemp at Qfan
+that was dropped at the BIOS)
+0x81 - off
+0x82 - slightly "on-ner" than off, but my fans do not get to move. I can
+hear the high-pitched PWM sound that motors give off at too-low-pwm.
+0x83 - now they do move. Estimate about 70% speed or so.
+0x84-0x8f - full on
+
+Changing the high nibble doesn't seem to do much except the high bit
+(0x80) must be set for PWM to work, else the current pwm doesn't seem to
+change.
+
+My mobo is an ASUS A7V266-E. This behavior is similar to what I got
+with speedfan under Windows, where 0-15% would be off, 15-2x% (can't
+remember the exact value) would be 70% and higher would be full on.

+Kernel driver w83l785ts
+=======================
+
+Supported chips:
+  * Winbond W83L785TS-S
+    Prefix: 'w83l785ts'
+    Addresses scanned: I2C 0x2e
+    Datasheet: Publicly available at the Winbond USA website
+               http://www.winbond-usa.com/products/winbond_products/pdfs/PCIC/W83L785TS-S.pdf
+
+Authors:
+        Jean Delvare <khali@linux-fr.org>
+
+Description
+-----------
+
+The W83L785TS-S is a digital temperature sensor. It senses the
+temperature of a single external diode. The high limit is
+theoretically defined as 85 or 100 degrees C through a combination
+of external resistors, so the user cannot change it. Values seen so
+far suggest that the two possible limits are actually 95 and 110
+degrees C. The datasheet is rather poor and obviously inaccurate
+on several points including this one.
+
+All temperature values are given in degrees Celsius. Resolution
+is 1.0 degree. See the datasheet for details.
+
+The w83l785ts driver will not update its values more frequently than
+every other second; reading them more often will do no harm, but will
+return 'old' values.
+
+Known Issues
+------------
+
+On some systems (Asus), the BIOS is known to interfere with the driver
+and cause read errors. The driver will retry a given number of times
+(5 by default) and then give up, returning the old value (or 0 if
+there is no old value). It seems to work well enough so that you should
+not notice anything. Thanks to James Bolt for helping test this feature.

-Description
------------
-
-The chips supported by this driver are very similar. The Maxim MAX1617 is
-the oldest; it has the problem that it is not very well detectable. The
-MAX1617A solves that. The ADM1021 is a straight clone of the MAX1617A.
-Ditto for the THMC10. From here on, we will refer to all these chips as
-ADM1021-clones.
-
-The ADM1021 and MAX1617A reports a die code, which is a sort of revision
-code. This can help us pinpoint problems; it is not very useful
-otherwise.
-
-ADM1021-clones implement two temperature sensors. One of them is internal,
-and measures the temperature of the chip itself; the other is external and
-is realised in the form of a transistor-like device. A special alarm
-indicates whether the remote sensor is connected.
-
-Each sensor has its own low and high limits. When they are crossed, the
-corresponding alarm is set and remains on as long as the temperature stays
-out of range. Temperatures are measured in degrees Celsius. Measurements
-are possible between -65 and +127 degrees, with a resolution of one degree.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may already
-have disappeared!
-
-This driver only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values. It is possible to make
-ADM1021-clones do faster measurements, but there is really no good reason
-for that.
-
-Xeon support
-------------
-
-Some Xeon processors have real max1617, adm1021, or compatible chips
-within them, with two temperature sensors.
-
-Other Xeons have chips with only one sensor.
-
-If you have a Xeon, and the adm1021 module loads, and both temperatures
-appear valid, then things are good.
-
-If the adm1021 module doesn't load, you should try this:
-	modprobe adm1021 force_adm1021=BUS,ADDRESS
-	ADDRESS can only be 0x18, 0x1a, 0x29, 0x2b, 0x4c, or 0x4e.
-
-If you have dual Xeons you may have appear to have two separate
-adm1021-compatible chips, or two single-temperature sensors, at distinct
-addresses.

-Description
------------
-
-(This is from Analog Devices.) The ADM1025 is a complete system hardware
-monitor for microprocessor-based systems, providing measurement and limit
-comparison of various system parameters. Five voltage measurement inputs
-are provided, for monitoring +2.5V, +3.3V, +5V and +12V power supplies and
-the processor core voltage. The ADM1025 can monitor a sixth power-supply
-voltage by measuring its own VCC. One input (two pins) is dedicated to a
-remote temperature-sensing diode and an on-chip temperature sensor allows
-ambient temperature to be monitored.
-
-One specificity of this chip is that the pin 11 can be hardwired in two
-different manners. It can act as the +12V power-supply voltage analog
-input, or as the a fifth digital entry for the VID reading (bit 4). It's
-kind of strange since both are useful, and the reason for designing the
-chip that way is obscure at least to me. The bit 5 of the configuration
-register can be used to define how the chip is hardwired. Please note that
-it is not a choice you have to make as the user. The choice was already
-made by your motherboard's maker. If the configuration bit isn't set
-properly, you'll have a wrong +12V reading or a wrong VID reading. The way
-the driver handles that is to preserve this bit through the initialization
-process, assuming that the BIOS set it up properly beforehand. If it turns
-out not to be true in some cases, we'll provide a module parameter to force
-modes.
-
-This driver also supports the ADM1025A, which differs from the ADM1025
-only in that it has "open-drain VID inputs while the ADM1025 has on-chip
-100k pull-ups on the VID inputs". It doesn't make any difference for us.

-Description
------------
-
-This driver implements support for the Analog Devices ADM1026. Analog
-Devices calls it a "complete thermal system management controller."
-
-The ADM1026 implements three (3) temperature sensors, 17 voltage sensors,
-16 general purpose digital I/O lines, eight (8) fan speed sensors (8-bit),
-an analog output and a PWM output along with limit, alarm and mask bits for
-all of the above. There is even 8k bytes of EEPROM memory on chip.
-
-Temperatures are measured in degrees Celsius. There are two external
-sensor inputs and one internal sensor. Each sensor has a high and low
-limit. If the limit is exceeded, an interrupt (#SMBALERT) can be
-generated. The interrupts can be masked. In addition, there are over-temp
-limits for each sensor. If this limit is exceeded, the #THERM output will
-be asserted. The current temperature and limits have a resolution of 1
-degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute) but measured
-in counts of a 22.5kHz internal clock. Each fan has a high limit which
-corresponds to a minimum fan speed. If the limit is exceeded, an interrupt
-can be generated. Each fan can be programmed to divide the reference clock
-by 1, 2, 4 or 8. Not all RPM values can accurately be represented, so some
-rounding is done. With a divider of 8, the slowest measurable speed of a
-two pulse per revolution fan is 661 RPM.
-
-There are 17 voltage sensors. An alarm is triggered if the voltage has
-crossed a programmable minimum or maximum limit. Note that minimum in this
-case always means 'closest to zero'; this is important for negative voltage
-measurements. Several inputs have integrated attenuators so they can measure
-higher voltages directly. 3.3V, 5V, 12V, -12V and battery voltage all have
-dedicated inputs. There are several inputs scaled to 0-3V full-scale range
-for SCSI terminator power. The remaining inputs are not scaled and have
-a 0-2.5V full-scale range. A 2.5V or 1.82V reference voltage is provided
-for negative voltage measurements.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may already
-have disappeared! Note that in the current implementation, all hardware
-registers are read whenever any data is read (unless it is less than 2.0
-seconds since the last update). This means that you can easily miss
-once-only alarms.
-
-The ADM1026 measures continuously. Analog inputs are measured about 4
-times a second. Fan speed measurement time depends on fan speed and
-divisor. It can take as long as 1.5 seconds to measure all fan speeds.
-
-The ADM1026 has the ability to automatically control fan speed based on the
-temperature sensor inputs. Both the PWM output and the DAC output can be
-used to control fan speed. Usually only one of these two outputs will be
-used. Write the minimum PWM or DAC value to the appropriate control
-register. Then set the low temperature limit in the tmin values for each
-temperature sensor. The range of control is fixed at 20 °C, and the
-largest difference between current and tmin of the temperature sensors sets
-the control output. See the datasheet for several example circuits for
-controlling fan speed with the PWM and DAC outputs. The fan speed sensors
-do not have PWM compensation, so it is probably best to control the fan
-voltage from the power lead rather than on the ground lead.
-
-The datasheet shows an example application with VID signals attached to
-GPIO lines. Unfortunately, the chip may not be connected to the VID lines
-in this way. The driver assumes that the chips *is* connected this way to
-get a VID voltage.

-
-Interface
----------
-The I2C addresses listed above assume BIOS has not changed the
-chip MSB 5-bit address. Each chip reports a unique manufacturer
-identification code as well as the chip revision/stepping level.
-
-Description
------------
-[From ADM9240] The ADM9240 is a complete system hardware monitor for
-microprocessor-based systems, providing measurement and limit comparison
-of up to four power supplies and two processor core voltages, plus
-temperature, two fan speeds and chassis intrusion. Measured values can
-be read out via an I2C-compatible serial System Management Bus, and values
-for limit comparisons can be programmed in over the same serial bus. The
-high speed successive approximation ADC allows frequent sampling of all
-analog channels to ensure a fast interrupt response to any out-of-limit
-measurement.
-
-The ADM9240, DS1780 and LM81 are register compatible, the following
-details are common to the three chips. Chip differences are described
-after this section.
-
-
-Measurements
-------------
-The measurement cycle
-
-The adm9240 driver will take a measurement reading no faster than once
-each two seconds. User-space may read sysfs interface faster than the
-measurement update rate and will receive cached data from the most
-recent measurement.
-
-ADM9240 has a very fast 320us temperature and voltage measurement cycle
-with independent fan speed measurement cycles counting alternating rising
-edges of the fan tacho inputs.
-
-DS1780 measurement cycle is about once per second including fan speed.
-
-LM81 measurement cycle is about once per 400ms including fan speed.
-The LM81 12-bit extended temperature measurement mode is not supported.
-
-Temperature
------------
-On chip temperature is reported as degrees Celsius as 9-bit signed data
-with resolution of 0.5 degrees Celsius. High and low temperature limits
-are 8-bit signed data with resolution of one degree Celsius.
-
-Temperature alarm is asserted once the temperature exceeds the high limit,
-and is cleared when the temperature falls below the temp1_max_hyst value.
-
-Fan Speed
----------
-Two fan tacho inputs are provided, the ADM9240 gates an internal 22.5kHz
-clock via a divider to an 8-bit counter. Fan speed (rpm) is calculated by:
-
-rpm = (22500 * 60) / (count * divider)
-
-Automatic fan clock divider
-
-  * User sets 0 to fan_min limit
-    - low speed alarm is disabled
-    - fan clock divider not changed
-    - auto fan clock adjuster enabled for valid fan speed reading
-
-  * User sets fan_min limit too low
-    - low speed alarm is enabled
-    - fan clock divider set to max
-    - fan_min set to register value 254 which corresponds
-      to 664 rpm on adm9240
-    - low speed alarm will be asserted if fan speed is
-      less than minimum measurable speed
-    - auto fan clock adjuster disabled
-
-  * User sets reasonable fan speed
-    - low speed alarm is enabled
-    - fan clock divider set to suit fan_min
-    - auto fan clock adjuster enabled: adjusts fan_min
-
-  * User sets unreasonably high low fan speed limit
-    - resolution of the low speed limit may be reduced
-    - alarm will be asserted
-    - auto fan clock adjuster enabled: adjusts fan_min
-
-    * fan speed may be displayed as zero until the auto fan clock divider
-      adjuster brings fan speed clock divider back into chip measurement
-      range, this will occur within a few measurement cycles.
-
-Analog Output
--------------
-An analog output provides a 0 to 1.25 volt signal intended for an external
-fan speed amplifier circuit. The analog output is set to maximum value on
-power up or reset. This doesn't do much on the test Intel SE440BX-2.
-
-Voltage Monitor
-
-Voltage (IN) measurement is internally scaled:
-
-    nr  label       nominal     maximum   resolution
-                      mV          mV         mV
-    0   +2.5V        2500        3320       13.0
-    1   Vccp1        2700        3600       14.1
-    2   +3.3V        3300        4380       17.2
-    3     +5V        5000        6640       26.0
-    4    +12V       12000       15940       62.5
-    5   Vccp2        2700        3600       14.1
-
-The reading is an unsigned 8-bit value, nominal voltage measurement is
-represented by a reading of 192, being 3/4 of the measurement range.
-
-An alarm is asserted for any voltage going below or above the set limits.
-
-The driver reports and accepts voltage limits scaled to the above table.
-
-VID Monitor
------------
-The chip has five inputs to read the 5-bit VID and reports the mV value
-based on detected CPU type.
-
-Chassis Intrusion
------------------
-An alarm is asserted when the CI pin goes active high. The ADM9240
-Datasheet has an example of an external temperature sensor driving
-this pin. On an Intel SE440BX-2 the Chassis Intrusion header is
-connected to a normally open switch.
-
-The ADM9240 provides an internal open drain on this line, and may output
-a 20 ms active low pulse to reset an external Chassis Intrusion latch.
-
-Clear the CI latch by writing value 1 to the sysfs chassis_clear file.
-
-Alarm flags reported as 16-bit word
-
-    bit     label               comment
-    ---     -------------       --------------------------
-     0      +2.5 V_Error        high or low limit exceeded
-     1      VCCP_Error          high or low limit exceeded
-     2      +3.3 V_Error        high or low limit exceeded
-     3      +5 V_Error          high or low limit exceeded
-     4      Temp_Error          temperature error
-     6      FAN1_Error          fan low limit exceeded
-     7      FAN2_Error          fan low limit exceeded
-     8      +12 V_Error         high or low limit exceeded
-     9      VCCP2_Error         high or low limit exceeded
-    12      Chassis_Error       CI pin went high
-
-Remaining bits are reserved and thus undefined. It is important to note
-that alarm bits may be cleared on read, user-space may latch alarms and
-provide the end-user with a method to clear alarm memory.

-Description
------------
-
-This driver implements support for the Asus ASB100 and ASB100-A "Bach".
-These are custom ASICs available only on Asus mainboards. Asus refuses to
-supply a datasheet for these chips. Thanks go to many people who helped
-investigate their hardware, including:
-
-Vitaly V. Bursov
-Alexander van Kaam (author of MBM for Windows)
-Bertrik Sikken
-
-The ASB100 implements seven voltage sensors, three fan rotation speed
-sensors, four temperature sensors, VID lines and alarms. In addition to
-these, the ASB100-A also implements a single PWM controller for fans 2 and
-3 (i.e. one setting controls both.) If you have a plain ASB100, the PWM
-controller will simply not work (or maybe it will for you... it doesn't for
-me).
-
-Temperatures are measured and reported in degrees Celsius.
-
-Fan speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit.
-
-Voltage sensors (also known as IN sensors) report values in volts.
-
-The VID lines encode the core voltage value: the voltage level your
-processor should work with. This is hardcoded by the mainboard and/or
-processor itself. It is a value in volts.
-
-Alarms: (TODO question marks indicate may or may not work)
-
-0x0001 => in0 (?)
-0x0002 => in1 (?)
-0x0004 => in2
-0x0008 => in3
-0x0010 => temp1 (1)

-0x0400 => in6 (?) (2)
-0x0800 => fan3
-0x1000 => chassis switch
-0x2000 => temp3
-
-Alarm Notes:
-
-(1) This alarm will only trigger if the hysteresis value is 127C.
-I.e. it behaves the same as w83781d.
-
-(2) The min and max registers for these values appear to
-be read-only or otherwise stuck at 0x00.
-
-TODO:
-* Experiment with fan divisors > 8.
-* Experiment with temp. sensor types.
-* Are there really 13 voltage inputs? Probably not...
-* Cleanups, no doubt...

-Module Parameters
-------------------
-
-* polarity int
-  Output's polarity: 0 = active high, 1 = active low
-
-Description
------------
-
-The DS1621 is a (one instance) digital thermometer and thermostat. It has
-both high and low temperature limits which can be user defined (i.e.
-programmed into non-volatile on-chip registers). Temperature range is -55
-degree Celsius to +125 in 0.5 increments. You may convert this into a
-Fahrenheit range of -67 to +257 degrees with 0.9 steps. If polarity
-parameter is not provided, original value is used.
-
-As for the thermostat, behavior can also be programmed using the polarity
-toggle. On the one hand ("heater"), the thermostat output of the chip,
-Tout, will trigger when the low limit temperature is met or underrun and
-stays high until the high limit is met or exceeded. On the other hand
-("cooler"), vice versa. That way "heater" equals "active low", whereas
-"conditioner" equals "active high". Please note that the DS1621 data sheet
-is somewhat misleading in this point since setting the polarity bit does
-not simply invert Tout.
-
-A second thing is that, during extensive testing, Tout showed a tolerance
-of up to +/- 0.5 degrees even when compared against precise temperature
-readings. Be sure to have a high vs. low temperature limit gap of al least
-1.0 degree Celsius to avoid Tout "bouncing", though!
-
-As for alarms, you can read the alarm status of the DS1621 via the 'alarms'
-/sys file interface. The result consists mainly of bit 6 and 5 of the
-configuration register of the chip; bit 6 (0x40 or 64) is the high alarm
-bit and bit 5 (0x20 or 32) the low one. These bits are set when the high or
-low limits are met or exceeded and are reset by the module as soon as the
-respective temperature ranges are left.
-
-The alarm registers are in no way suitable to find out about the actual
-status of Tout. They will only tell you about its history, whether or not
-any of the limits have ever been met or exceeded since last power-up or
-reset. Be aware: When testing, it showed that the status of Tout can change
-with neither of the alarms set.
-
-Temperature conversion of the DS1621 takes up to 1000ms; internal access to
-non-volatile registers may last for 10ms or below.
-
-High Accuracy Temperature Reading
----------------------------------
-
-As said before, the temperature issued via the 9-bit i2c-bus data is
-somewhat arbitrary. Internally, the temperature conversion is of a
-different kind that is explained (not so...) well in the DS1621 data sheet.
-To cut the long story short: Inside the DS1621 there are two oscillators,
-both of them biassed by a temperature coefficient.
-
-Higher resolution of the temperature reading can be achieved using the
-internal projection, which means taking account of REG_COUNT and REG_SLOPE
-(the driver manages them):
-
-Taken from Dallas Semiconductors App Note 068: 'Increasing Temperature
-Resolution on the DS1620' and App Note 105: 'High Resolution Temperature
-Measurement with Dallas Direct-to-Digital Temperature Sensors'
-
-- Read the 9-bit temperature and strip the LSB (Truncate the .5 degs)
-- The resulting value is TEMP_READ.
-- Then, read REG_COUNT.
-- And then, REG_SLOPE.
-
-      TEMP = TEMP_READ - 0.25 + ((REG_SLOPE - REG_COUNT) / REG_SLOPE)
-
-Note that this is what the DONE bit in the DS1621 configuration register is
-good for: Internally, one temperature conversion takes up to 1000ms. Before
-that conversion is complete you will not be able to read valid things out
-of REG_COUNT and REG_SLOPE. The DONE bit, as you may have guessed by now,
-tells you whether the conversion is complete ("done", in plain English) and
-thus, whether the values you read are good or not.
-
-The DS1621 has two modes of operation: "Continuous" conversion, which can
-be understood as the default stand-alone mode where the chip gets the
-temperature and controls external devices via its Tout pin or tells other
-i2c's about it if they care. The other mode is called "1SHOT", that means
-that it only figures out about the temperature when it is explicitly told
-to do so; this can be seen as power saving mode.
-
-Now if you want to read REG_COUNT and REG_SLOPE, you have to either stop
-the continuous conversions until the contents of these registers are valid,
-or, in 1SHOT mode, you have to have one conversion made.

-Description
------------
-
-This driver implements support for the Fujitsu-Siemens Hermes chip. It is
-described in the 'Register Set Specification BMC Hermes based Systemboard'
-from Fujitsu-Siemens.
-
-The Hermes chip implements a hardware-based system management, e.g. for
-controlling fan speed and core voltage. There is also a watchdog counter on
-the chip which can trigger an alarm and even shut the system down.
-
-The chip provides three temperature values (CPU, motherboard and
-auxiliary), three voltage values (+12V, +5V and battery) and three fans
-(power supply, CPU and auxiliary).
-
-Temperatures are measured in degrees Celsius. The resolution is 1 degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute). The value
-can be divided by a programmable divider (1, 2 or 4) which is stored on
-the chip.
-
-Voltage sensors (also known as "in" sensors) report their values in volts.
-
-All values are reported as final values from the driver. There is no need
-for further calculations.
-
-
-Detailed description
---------------------
-
-Below you'll find a single line description of all the bit values. With
-this information, you're able to decode e. g. alarms, wdog, etc. To make
-use of the watchdog, you'll need to set the watchdog time and enable the
-watchdog. After that it is necessary to restart the watchdog time within
-the specified period of time, or a system reset will occur.

-Limitations
------------
-
-* Measuring fan speed
-It seems that the chip counts "ripples" (typical fans produce 2 ripples per
-rotation while VERAX fans produce 18) in a 9-bit register. This register is
-read out every second, then the ripple prescaler (2, 4 or 8) is applied and
-the result is stored in the 8 bit output register. Due to the limitation of
-the counting register to 9 bits, it is impossible to measure a VERAX fan
-properly (even with a prescaler of 8). At its maximum speed of 3500 RPM the
-fan produces 1080 ripples per second which causes the counting register to
-overflow twice, leading to only 186 RPM.
-
-* Measuring input voltages
-in2 ("battery") reports the voltage of the onboard lithium battery and not
-+3.3V from the power supply.
-
-* Undocumented features
-Fujitsu-Siemens Computers has not documented all features of the chip so
-far. Their software, System Guard, shows that there are a still some
-features which cannot be controlled by this implementation.

-Description
------------
-
-IMPORTANT:
-
-For the revision 0x00 chip, the in0, in1, and in2  values (+5V, +3V,
-and +12V) CANNOT be read. This is a limitation of the chip, not the driver.
-
-This driver supports the Genesys Logic GL518SM chip. There are at least
-two revision of this chip, which we call revision 0x00 and 0x80. Revision
-0x80 chips support the reading of all voltages and revision 0x00 only
-for VIN3.
-
-The GL518SM implements one temperature sensor, two fan rotation speed
-sensors, and four voltage sensors. It can report alarms through the
-computer speakers.
-
-Temperatures are measured in degrees Celsius. An alarm goes off while the
-temperature is above the over temperature limit, and has not yet dropped
-below the hysteresis limit. The alarm always reflects the current
-situation. Measurements are guaranteed between -10 degrees and +110
-degrees, with a accuracy of +/-3 degrees.
-
-Rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. In
-case when you have selected to turn fan1 off, no fan1 alarm is triggered.
-
-Fan readings can be divided by a programmable divider (1, 2, 4 or 8) to
-give the readings more range or accuracy.  Not all RPM values can
-accurately be represented, so some rounding is done. With a divider
-of 2, the lowest representable value is around 1900 RPM.
-
-Voltage sensors (also known as VIN sensors) report their values in volts.
-An alarm is triggered if the voltage has crossed a programmable minimum or
-maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. The VDD input
-measures voltages between 0.000 and 5.865 volt, with a resolution of 0.023
-volt. The other inputs measure voltages between 0.000 and 4.845 volt, with
-a resolution of 0.019 volt. Note that revision 0x00 chips do not support
-reading the current voltage of any input except for VIN3; limit setting and
-alarms work fine, though.
-
-When an alarm is triggered, you can be warned by a beeping signal through your
-computer speaker. It is possible to enable all beeping globally, or only the
-beeping for some alarms.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once (except for temperature alarms). This means that the
-cause for the alarm may already have disappeared! Note that in the current
-implementation, all hardware registers are read whenever any data is read
-(unless it is less than 1.5 seconds since the last update). This means that
-you can easily miss once-only alarms.
-
-The GL518SM only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.

-Module Parameters
------------------
-
-* update_vbat: int
-
-  0 if vbat should report power on value, 1 if vbat should be updated after
-  each read. Default is 0. On some boards the battery voltage is provided
-  by either the battery or the onboard power supply. Only the first reading
-  at power on will be the actual battery voltage (which the chip does
-  automatically). On other boards the battery voltage is always fed to
-  the chip so can be read at any time. Excessive reading may decrease
-  battery life but no information is given in the datasheet.
-
-* fix_pwm_polarity int
-
-  Force PWM polarity to active high (DANGEROUS). Some chips are
-  misconfigured by BIOS - PWM values would be inverted. This option tries
-  to fix this. Please contact your BIOS manufacturer and ask him for fix.
-
-Description
------------
-
-This driver implements support for the IT8705F, IT8712F and SiS950 chips.
-
-This driver also supports IT8712F, which adds SMBus access, and a VID
-input, used to report the Vcore voltage of the Pentium processor.
-The IT8712F additionally features VID inputs.
-
-These chips are 'Super I/O chips', supporting floppy disks, infrared ports,
-joysticks and other miscellaneous stuff. For hardware monitoring, they
-include an 'environment controller' with 3 temperature sensors, 3 fan
-rotation speed sensors, 8 voltage sensors, and associated alarms.
-
-Temperatures are measured in degrees Celsius. An alarm is triggered once
-when the Overtemperature Shutdown limit is crossed.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give the
-readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in volts. An
-alarm is triggered if the voltage has crossed a programmable minimum or
-maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. All voltage
-inputs can measure voltages between 0 and 4.08 volts, with a resolution of
-0.016 volt. The battery voltage in8 does not have limit registers.
-
-The VID lines (IT8712F only) encode the core voltage value: the voltage
-level your processor should work with. This is hardcoded by the mainboard
-and/or processor itself. It is a value in volts.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may already
-have disappeared! Note that in the current implementation, all hardware
-registers are read whenever any data is read (unless it is less than 1.5
-seconds since the last update). This means that you can easily miss
-once-only alarms.
-
-The IT87xx only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.
-
-To change sensor N to a thermistor, 'echo 2 > tempN_type' where N is 1, 2,
-or 3. To change sensor N to a thermal diode, 'echo 3 > tempN_type'.
-Give 0 for unused sensor. Any other value is invalid. To configure this at
-startup, consult lm_sensors's /etc/sensors.conf. (2 = thermistor;
-3 = thermal diode)
-
-The fan speed control features are limited to manual PWM mode. Automatic

-  http://www.tyan.com/
-
-Description
------------
-
-The LM63 is a digital temperature sensor with integrated fan monitoring
-and control.
-
-The LM63 is basically an LM86 with fan speed monitoring and control
-capabilities added. It misses some of the LM86 features though:
- - No low limit for local temperature.
- - No critical limit for local temperature.
- - Critical limit for remote temperature can be changed only once. We
-   will consider that the critical limit is read-only.
-
-The datasheet isn't very clear about what the tachometer reading is.
-
-An explanation from National Semiconductor: The two lower bits of the read
-value have to be masked out. The value is still 16 bit in width.
-
-All temperature values are given in degrees Celsius. Resolution is 1.0
-degree for the local temperature, 0.125 degree for the remote temperature.
-
-The fan speed is measured using a tachometer. Contrary to most chips which
-store the value in an 8-bit register and have a selectable clock divider
-to make sure that the result will fit in the register, the LM63 uses 16-bit
-value for measuring the speed of the fan. It can measure fan speeds down to
-83 RPM, at least in theory.
-
-Note that the pin used for fan monitoring is shared with an alert out
-function. Depending on how the board designer wanted to use the chip, fan
-speed monitoring will or will not be possible. The proper chip configuration
-is left to the BIOS, and the driver will blindly trust it.
-
-A PWM output can be used to control the speed of the fan. The LM63 has two
-PWM modes: manual and automatic. Automatic mode is not fully implemented yet
-(you cannot define your custom PWM/temperature curve), and mode change isn't
-supported either.
-
-The lm63 driver will not update its values more frequently than every
-second; reading them more often will do no harm, but will return 'old'
-values.

-Description
------------
-
-The LM75 implements one temperature sensor. Limits can be set through the
-Overtemperature Shutdown register and Hysteresis register. Each value can be
-set and read to half-degree accuracy.
-An alarm is issued (usually to a connected LM78) when the temperature
-gets higher then the Overtemperature Shutdown value; it stays on until
-the temperature falls below the Hysteresis value.
-All temperatures are in degrees Celsius, and are guaranteed within a
-range of -55 to +125 degrees.
-
-The LM75 only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.
-
-The LM75 is usually used in combination with LM78-like chips, to measure
-the temperature of the processor(s).
-
-The DS75, DS1775, MAX6625, and MAX6626 are supported as well.
-They are not distinguished from an LM75. While most of these chips
-have three additional bits of accuracy (12 vs. 9 for the LM75),
-the additional bits are not supported. Not only that, but these chips will
-not be detected if not in 9-bit precision mode (use the force parameter if
-needed).
-
-The TCN75 is supported as well, and is not distinguished from an LM75.
-
-The LM75 is essentially an industry standard; there may be other
-LM75 clones not listed here, with or without various enhancements,
-that are supported.
-
-The LM77 is not supported, contrary to what we pretended for a long time.
-Both chips are simply not compatible, value encoding differs.

-Description
------------
-
-This driver implements support for the National Semiconductor LM78, LM78-J
-and LM79. They are described as 'Microprocessor System Hardware Monitors'.
-
-There is almost no difference between the three supported chips. Functionally,
-the LM78 and LM78-J are exactly identical. The LM79 has one more VID line,
-which is used to report the lower voltages newer Pentium processors use.
-From here on, LM7* means either of these three types.
-
-The LM7* implements one temperature sensor, three fan rotation speed sensors,
-seven voltage sensors, VID lines, alarms, and some miscellaneous stuff.
-
-Temperatures are measured in degrees Celsius. An alarm is triggered once
-when the Overtemperature Shutdown limit is crossed; it is triggered again
-as soon as it drops below the Hysteresis value. A more useful behavior
-can be found by setting the Hysteresis value to +127 degrees Celsius; in
-this case, alarms are issued during all the time when the actual temperature
-is above the Overtemperature Shutdown value. Measurements are guaranteed
-between -55 and +125 degrees, with a resolution of 1 degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in volts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. All voltage
-inputs can measure voltages between 0 and 4.08 volts, with a resolution
-of 0.016 volt.
-
-The VID lines encode the core voltage value: the voltage level your processor
-should work with. This is hardcoded by the mainboard and/or processor itself.
-It is a value in volts. When it is unconnected, you will often find the
-value 3.50 V here.
-
-In addition to the alarms described above, there are a couple of additional
-ones. There is a BTI alarm, which gets triggered when an external chip has
-crossed its limits. Usually, this is connected to all LM75 chips; if at
-least one crosses its limits, this bit gets set. The CHAS alarm triggers
-if your computer case is open. The FIFO alarms should never trigger; it
-indicates an internal error. The SMI_IN alarm indicates some other chip
-has triggered an SMI interrupt. As we do not use SMI interrupts at all,
-this condition usually indicates there is a problem with some other
-device.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared! Note that in the current implementation, all
-hardware registers are read whenever any data is read (unless it is less
-than 1.5 seconds since the last update). This means that you can easily
-miss once-only alarms.
-
-The LM7* only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.

-The LM80 implements one temperature sensor, two fan rotation speed sensors,
-seven voltage sensors, alarms, and some miscellaneous stuff.
-
-Temperatures are measured in degrees Celsius. There are two sets of limits
-which operate independently. When the HOT Temperature Limit is crossed,
-this will cause an alarm that will be reasserted until the temperature
-drops below the HOT Hysteresis. The Overtemperature Shutdown (OS) limits
-should work in the same way (but this must be checked; the datasheet
-is unclear about this). Measurements are guaranteed between -55 and
-+125 degrees. The current temperature measurement has a resolution of
-0.0625 degrees; the limits have a resolution of 1 degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in volts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. All voltage
-inputs can measure voltages between 0 and 2.55 volts, with a resolution
-of 0.01 volt.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared! Note that in the current implementation, all
-hardware registers are read whenever any data is read (unless it is less
-than 2.0 seconds since the last update). This means that you can easily
-miss once-only alarms.
-
-The LM80 only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.

-Description
------------
-
-The LM83 is a digital temperature sensor. It senses its own temperature as
-well as the temperature of up to three external diodes. It is compatible
-with many other devices such as the LM84 and all other ADM1021 clones.
-The main difference between the LM83 and the LM84 in that the later can
-only sense the temperature of one external diode.
-
-Using the adm1021 driver for a LM83 should work, but only two temperatures
-will be reported instead of four.
-
-The LM83 is only found on a handful of motherboards. Both a confirmed
-list and an unconfirmed list follow. If you can confirm or infirm the
-fact that any of these motherboards do actually have an LM83, please
-contact us. Note that the LM90 can easily be misdetected as a LM83.
-
-Confirmed motherboards:
-    SBS         P014
-
-Unconfirmed motherboards:
-    Gigabyte    GA-8IK1100
-    Iwill       MPX2
-    Soltek      SL-75DRV5
-
-The driver has been successfully tested by Magnus Forsström, who I'd
-like to thank here. More testers will be of course welcome.
-
-The fact that the LM83 is only scarcely used can be easily explained.
-Most motherboards come with more than just temperature sensors for
-health monitoring. They also have voltage and fan rotation speed
-sensors. This means that temperature-only chips are usually used as
-secondary chips coupled with another chip such as an IT8705F or similar
-chip, which provides more features. Since systems usually need three
-temperature sensors (motherboard, processor, power supply) and primary
-chips provide some temperature sensors, the secondary chip, if needed,
-won't have to handle more than two temperatures. Thus, ADM1021 clones
-are sufficient, and there is no need for a four temperatures sensor
-chip such as the LM83. The only case where using an LM83 would make
-sense is on SMP systems, such as the above-mentioned Iwill MPX2,
-because you want an additional temperature sensor for each additional
-CPU.
-
-On the SBS P014, this is different, since the LM83 is the only hardware
-monitoring chipset. One temperature sensor is used for the motherboard
-(actually measuring the LM83's own temperature), one is used for the
-CPU. The two other sensors must be used to measure the temperature of
-two other points of the motherboard. We suspect these points to be the
-north and south bridges, but this couldn't be confirmed.
-
-All temperature values are given in degrees Celsius. Local temperature
-is given within a range of 0 to +85 degrees. Remote temperatures are
-given within a range of 0 to +125 degrees. Resolution is 1.0 degree,
-accuracy is guaranteed to 3.0 degrees (see the datasheet for more
-details).
-
-Each sensor has its own high limit, but the critical limit is common to
-all four sensors. There is no hysteresis mechanism as found on most
-recent temperature sensors.
-
-The lm83 driver will not update its values more frequently than every
-other second; reading them more often will do no harm, but will return
-'old' values.

-Description
------------
-
-This driver implements support for the National Semiconductor LM85 and
-compatible chips including the Analog Devices ADM1027, ADT7463 and
-SMSC EMC6D10x chips family.
-
-The LM85 uses the 2-wire interface compatible with the SMBUS 2.0
-specification. Using an analog to digital converter it measures three (3)
-temperatures and five (5) voltages. It has four (4) 16-bit counters for
-measuring fan speed. Five (5) digital inputs are provided for sampling the
-VID signals from the processor to the VRM. Lastly, there are three (3) PWM
-outputs that can be used to control fan speed.
-
-The voltage inputs have internal scaling resistors so that the following
-voltage can be measured without external resistors:
-
-  2.5V, 3.3V, 5V, 12V, and CPU core voltage (2.25V)
-
-The temperatures measured are one internal diode, and two remote diodes.
-Remote 1 is generally the CPU temperature. These inputs are designed to
-measure a thermal diode like the one in a Pentium 4 processor in a socket
-423 or socket 478 package. They can also measure temperature using a
-transistor like the 2N3904.
-
-A sophisticated control system for the PWM outputs is designed into the
-LM85 that allows fan speed to be adjusted automatically based on any of the
-three temperature sensors. Each PWM output is individually adjustable and
-programmable. Once configured, the LM85 will adjust the PWM outputs in
-response to the measured temperatures without further host intervention.
-This feature can also be disabled for manual control of the PWM's.
-
-Each of the measured inputs (voltage, temperature, fan speed) has
-corresponding high/low limit values. The LM85 will signal an ALARM if any
-measured value exceeds either limit.
-
-The LM85 samples all inputs continuously. The lm85 driver will not read
-the registers more often than once a second. Further, configuration data is
-only read once each 5 minutes. There is twice as much config data as
-measurements, so this would seem to be a worthwhile optimization.
-
-Special Features
-----------------
-
-The LM85 has four fan speed monitoring modes. The ADM1027 has only two.
-Both have special circuitry to compensate for PWM interactions with the
-TACH signal from the fans. The ADM1027 can be configured to measure the
-speed of a two wire fan, but the input conditioning circuitry is different
-for 3-wire and 2-wire mode. For this reason, the 2-wire fan modes are not
-exposed to user control. The BIOS should initialize them to the correct
-mode. If you've designed your own ADM1027, you'll have to modify the
-init_client function and add an insmod parameter to set this up.
-
-To smooth the response of fans to changes in temperature, the LM85 has an
-optional filter for smoothing temperatures. The ADM1027 has the same
-config option but uses it to rate limit the changes to fan speed instead.
-
-The ADM1027 and ADT7463 have a 10-bit ADC and can therefore measure
-temperatures with 0.25 degC resolution. They also provide an offset to the
-temperature readings that is automatically applied during measurement.
-This offset can be used to zero out any errors due to traces and placement.
-The documentation says that the offset is in 0.25 degC steps, but in
-initial testing of the ADM1027 it was 1.00 degC steps. Analog Devices has
-confirmed this "bug". The ADT7463 is reported to work as described in the
-documentation. The current lm85 driver does not show the offset register.
-
-The ADT7463 has a THERM asserted counter. This counter has a 22.76ms
-resolution and a range of 5.8 seconds. The driver implements a 32-bit
-accumulator of the counter value to extend the range to over a year. The
-counter will stay at it's max value until read.
-
-See the vendor datasheets for more information. There is application note
-from National (AN-1260) with some additional information about the LM85.
-The Analog Devices datasheet is very detailed and describes a procedure for
-determining an optimal configuration for the automatic PWM control.
-
-The SMSC EMC6D100 & EMC6D101 monitor external voltages, temperatures, and
-fan speeds. They use this monitoring capability to alert the system to out
-of limit conditions and can automatically control the speeds of multiple
-fans in a PC or embedded system. The EMC6D101, available in a 24-pin SSOP
-package, and the EMC6D100, available in a 28-pin SSOP package, are designed
-to be register compatible. The EMC6D100 offers all the features of the
-EMC6D101 plus additional voltage monitoring and system control features.
-Unfortunately it is not possible to distinguish between the package
-versions on register level so these additional voltage inputs may read
-zero. The EMC6D102 features addtional ADC bits thus extending precision
-of voltage and temperature channels.
-
-
-Hardware Configurations
------------------------
-
-The LM85 can be jumpered for 3 different SMBus addresses. There are
-no other hardware configuration options for the LM85.
-
-The lm85 driver detects both LM85B and LM85C revisions of the chip. See the
-datasheet for a complete description of the differences. Other than
-identifying the chip, the driver behaves no differently with regard to
-these two chips. The LM85B is recommended for new designs.
-
-The ADM1027 and ADT7463 chips have an optional SMBALERT output that can be
-used to signal the chipset in case a limit is exceeded or the temperature
-sensors fail. Individual sensor interrupts can be masked so they won't
-trigger SMBALERT. The SMBALERT output if configured replaces one of the other
-functions (PWM2 or IN0). This functionality is not implemented in current
-driver.
-
-The ADT7463 also has an optional THERM output/input which can be connected
-to the processor PROC_HOT output. If available, the autofan control
-dynamic Tmin feature can be enabled to keep the system temperature within
-spec (just?!) with the least possible fan noise.
-
-Configuration Notes
--------------------
-
-Besides standard interfaces driver adds following:
-
-* Temperatures and Zones
-
-Each temperature sensor is associated with a Zone. There are three
-sensors and therefore three zones (# 1, 2 and 3). Each zone has the following
-temperature configuration points:
-
-* temp#_auto_temp_off - temperature below which fans should be off or spinning very low.
-* temp#_auto_temp_min - temperature over which fans start to spin.
-* temp#_auto_temp_max - temperature when fans spin at full speed.
-* temp#_auto_temp_crit - temperature when all fans will run full speed.
-
-* PWM Control
-
-There are three PWM outputs. The LM85 datasheet suggests that the
-pwm3 output control both fan3 and fan4. Each PWM can be individually
-configured and assigned to a zone for it's control value. Each PWM can be
-configured individually according to the following options.
-
-* pwm#_auto_pwm_min - this specifies the PWM value for temp#_auto_temp_off
-                      temperature. (PWM value from 0 to 255)
-
-* pwm#_auto_pwm_freq - select base frequency of PWM output. You can select
-                       in range of 10.0 to 94.0 Hz in .1 Hz units.
-		       (Values 100 to 940).
-
-The pwm#_auto_pwm_freq can be set to one of the following 8 values. Setting the
-frequency to a value not on this list, will result in the next higher frequency
-being selected. The actual device frequency may vary slightly from this
-specification as designed by the manufacturer. Consult the datasheet for more
-details. (PWM Frequency values:  100, 150, 230, 300, 380, 470, 620, 940)
-
-* pwm#_auto_pwm_minctl - this flags selects for temp#_auto_temp_off temperature
-                         the bahaviour of fans. Write 1 to let fans spinning at
-			 pwm#_auto_pwm_min or write 0 to let them off.
-
-NOTE: It has been reported that there is a bug in the LM85 that causes the flag
-to be associated with the zones not the PWMs. This contradicts all the
-published documentation. Setting pwm#_min_ctl in this case actually affects all
-PWMs controlled by zone '#'.
-
-* PWM Controlling Zone selection
-
-* pwm#_auto_channels - controls zone that is associated with PWM
-
-Configuration choices:
-
-   Value     Meaning
-  ------  ------------------------------------------------
-      1    Controlled by Zone 1
-      2    Controlled by Zone 2
-      3    Controlled by Zone 3
-     23    Controlled by higher temp of Zone 2 or 3
-    123    Controlled by highest temp of Zone 1, 2 or 3
-      0    PWM always 0%  (off)
-     -1    PWM always 100%  (full on)
-     -2    Manual control (write to 'pwm#' to set)
-
-The National LM85's have two vendor specific configuration
-features. Tach. mode and Spinup Control. For more details on these,
-see the LM85 datasheet or Application Note AN-1260.
-
-The Analog Devices ADM1027 has several vendor specific enhancements.
-The number of pulses-per-rev of the fans can be set, Tach monitoring
-can be optimized for PWM operation, and an offset can be applied to
-the temperatures to compensate for systemic errors in the
-measurements.
-
-In addition to the ADM1027 features, the ADT7463 also has Tmin control
-and THERM asserted counts. Automatic Tmin control acts to adjust the
-Tmin value to maintain the measured temperature sensor at a specified
-temperature. There isn't much documentation on this feature in the
-ADT7463 data sheet. This is not supported by current driver.

-Description
------------
-
-This driver implements support for the National Semiconductor LM87.
-
-The LM87 implements up to three temperature sensors, up to two fan
-rotation speed sensors, up to seven voltage sensors, alarms, and some
-miscellaneous stuff.
-
-Temperatures are measured in degrees Celsius. Each input has a high
-and low alarm settings. A high limit produces an alarm when the value
-goes above it, and an alarm is also produced when the value goes below
-the low limit.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in
-volts. An alarm is triggered if the voltage has crossed a programmable
-minimum or maximum limit. Note that minimum in this case always means
-'closest to zero'; this is important for negative voltage measurements.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared! Note that in the current implementation, all
-hardware registers are read whenever any data is read (unless it is less
-than 1.0 seconds since the last update). This means that you can easily
-miss once-only alarms.
-
-The lm87 driver only updates its values each 1.0 seconds; reading it more
-often will do no harm, but will return 'old' values.
-
-
-Hardware Configurations
------------------------
-
-The LM87 has four pins which can serve one of two possible functions,
-depending on the hardware configuration.
-
-Some functions share pins, so not all functions are available at the same
-time. Which are depends on the hardware setup. This driver assumes that
-the BIOS configured the chip correctly. In that respect, it differs from
-the original driver (from lm_sensors for Linux 2.4), which would force the
-LM87 to an arbitrary, compile-time chosen mode, regardless of the actual
-chipset wiring.
-
-For reference, here is the list of exclusive functions:
- - in0+in5 (default) or temp3
- - fan1 (default) or in6
- - fan2 (default) or in7
- - VID lines (default) or IRQ lines (not handled by this driver)

-Description
------------
-
-The LM90 is a digital temperature sensor. It senses its own temperature as
-well as the temperature of up to one external diode. It is compatible
-with many other devices such as the LM86, the LM89, the LM99, the ADM1032,
-the MAX6657, MAX6658 and the MAX6659 all of which are supported by this driver.
-Note that there is no easy way to differentiate between the last three
-variants. The extra address and features of the MAX6659 are not supported by
-this driver. Additionally, the ADT7461 is supported if found in ADM1032
-compatibility mode.
-
-The specificity of this family of chipsets over the ADM1021/LM84
-family is that it features critical limits with hysteresis, and an
-increased resolution of the remote temperature measurement.
-
-The different chipsets of the family are not strictly identical, although
-very similar. This driver doesn't handle any specific feature for now,
-but could if there ever was a need for it. For reference, here comes a
-non-exhaustive list of specific features:
-
-LM90:
-  * Filter and alert configuration register at 0xBF.
-  * ALERT is triggered by temperatures over critical limits.
-
-LM86 and LM89:
-  * Same as LM90
-  * Better external channel accuracy
-
-LM99:
-  * Same as LM89
-  * External temperature shifted by 16 degrees down
-
-ADM1032:
-  * Consecutive alert register at 0x22.
-  * Conversion averaging.
-  * Up to 64 conversions/s.
-  * ALERT is triggered by open remote sensor.
-
-ADT7461
-  * Extended temperature range (breaks compatibility)
-  * Lower resolution for remote temperature
-
-MAX6657 and MAX6658:
-  * Remote sensor type selection
-
-MAX6659
-  * Selectable address
-  * Second critical temperature limit
-  * Remote sensor type selection
-
-All temperature values are given in degrees Celsius. Resolution
-is 1.0 degree for the local temperature, 0.125 degree for the remote
-temperature.
-
-Each sensor has its own high and low limits, plus a critical limit.
-Additionally, there is a relative hysteresis value common to both critical
-values. To make life easier to user-space applications, two absolute values
-are exported, one for each channel, but these values are of course linked.
-Only the local hysteresis can be set from user-space, and the same delta
-applies to the remote hysteresis.
-
-The lm90 driver will not update its values more frequently than every
-other second; reading them more often will do no harm, but will return
-'old' values.

-Description
------------
-
-This driver implements support for the National Semiconductor LM92
-temperature sensor.
-
-Each LM92 temperature sensor supports a single temperature sensor. There are
-alarms for high, low, and critical thresholds. There's also an hysteresis to
-control the thresholds for resetting alarms.
-
-Support was added later for the LM76 and Maxim MAX6633/MAX6634/MAX6635,
-which are mostly compatible. They have not all been tested, so you
-may need to use the force parameter.

-
-All temperature values are given in degrees Celsius. Resolution
-is 1.0 degree for the local temperature and for the remote temperature.
-
-Only the external sensor has high and low limits.
-
-The max1619 driver will not update its values more frequently than every
-other second; reading them more often will do no harm, but will return
-'old' values.

-Module Parameters
------------------
-
-* init int
-  Chip initialization level:
-   0: None
-  *1: Forcibly enable internal voltage and temperature channels, except in9
-   2: Forcibly enable all voltage and temperature channels, except in9
-   3: Forcibly enable all voltage and temperature channels, including in9
-
-Note that this parameter has no effect for the PC87360, PC87363 and PC87364
-chips.
-
-Also note that for the PC87366, initialization levels 2 and 3 don't enable
-all temperature channels, because some of them share pins with each other,
-so they can't be used at the same time.
-
-
-Description
------------
-
-The National Semiconductor PC87360 Super I/O chip contains monitoring and
-PWM control circuitry for two fans. The PC87363 chip is similar, and the
-PC87364 chip has monitoring and PWM control for a third fan.
-
-The National Semiconductor PC87365 and PC87366 Super I/O chips are complete
-hardware monitoring chipsets, not only controlling and monitoring three fans,
-but also monitoring eleven voltage inputs and two (PC87365) or up to four
-(PC87366) temperatures.

-
-The driver assumes that no more than one chip is present, and one of the
-standard Super I/O addresses is used (0x2E/0x2F or 0x4E/0x4F)
-
-Fan Monitoring
---------------
-
-Fan rotation speeds are reported in RPM (revolutions per minute). An alarm
-is triggered if the rotation speed has dropped below a programmable limit.
-A different alarm is triggered if the fan speed is too low to be measured.
-
-Fan readings are affected by a programmable clock divider, giving the
-readings more range or accuracy. Usually, users have to learn how it works,
-but this driver implements dynamic clock divider selection, so you don't
-have to care no more.
-
-For reference, here are a few values about clock dividers:
-
-                slowest         accuracy        highest
-                measurable      around 3000     accurate
-    divider     speed (RPM)     RPM (RPM)       speed (RPM)
-         1        1882              18           6928
-         2         941              37           4898
-         4         470              74           3464
-         8         235             150           2449
-
-For the curious, here is how the values above were computed:
- * slowest measurable speed: clock/(255*divider)
- * accuracy around 3000 RPM: 3000^2/clock
- * highest accurate speed: sqrt(clock*100)
-The clock speed for the PC87360 family is 480 kHz. I arbitrarily chose 100
-RPM as the lowest acceptable accuracy.
-
-As mentioned above, you don't have to care about this no more.
-
-Note that not all RPM values can be represented, even when the best clock
-divider is selected. This is not only true for the measured speeds, but
-also for the programmable low limits, so don't be surprised if you try to
-set, say, fan1_min to 2900 and it finally reads 2909.
-
-
-Fan Control
------------
-
-PWM (pulse width modulation) values range from 0 to 255, with 0 meaning
-that the fan is stopped, and 255 meaning that the fan goes at full speed.
-
-Be extremely careful when changing PWM values. Low PWM values, even
-non-zero, can stop the fan, which may cause irreversible damage to your
-hardware if temperature increases too much. When changing PWM values, go
-step by step and keep an eye on temperatures.
-
-One user reported problems with PWM. Changing PWM values would break fan
-speed readings. No explanation nor fix could be found.
-
-
-Temperature Monitoring
-----------------------
-
-Temperatures are reported in degrees Celsius. Each temperature measured has
-associated low, high and overtemperature limits, each of which triggers an
-alarm when crossed.
-
-The first two temperature channels are external. The third one (PC87366
-only) is internal.
-
-The PC87366 has three additional temperature channels, based on
-thermistors (as opposed to thermal diodes for the first three temperature
-channels). For technical reasons, these channels are held by the VLM
-(voltage level monitor) logical device, not the TMS (temperature
-measurement) one. As a consequence, these temperatures are exported as
-voltages, and converted into temperatures in user-space.
-
-Note that these three additional channels share their pins with the
-external thermal diode channels, so you (physically) can't use them all at
-the same time. Although it should be possible to mix the two sensor types,
-the documents from National Semiconductor suggest that motherboard
-manufacturers should choose one type and stick to it. So you will more
-likely have either channels 1 to 3 (thermal diodes) or 3 to 6 (internal
-thermal diode, and thermistors).
-
-
-Voltage Monitoring
-------------------
-
-Voltages are reported relatively to a reference voltage, either internal or
-external. Some of them (in7:Vsb, in8:Vdd and in10:AVdd) are divided by two
-internally, you will have to compensate in sensors.conf. Others (in0 to in6)
-are likely to be divided externally. The meaning of each of these inputs as
-well as the values of the resistors used for division is left to the
-motherboard manufacturers, so you will have to document yourself and edit
-sensors.conf accordingly. National Semiconductor has a document with
-recommended resistor values for some voltages, but this still leaves much
-room for per motherboard specificities, unfortunately. Even worse,
-motherboard manufacturers don't seem to care about National Semiconductor's
-recommendations.
-
-Each voltage measured has associated low and high limits, each of which
-triggers an alarm when crossed.
-
-When available, VID inputs are used to provide the nominal CPU Core voltage.
-The driver will default to VRM 9.0, but this can be changed from user-space.
-The chipsets can handle two sets of VID inputs (on dual-CPU systems), but
-the driver will only export one for now. This may change later if there is
-a need.
-
-
-General Remarks
----------------
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may already
-have disappeared! Note that all hardware registers are read whenever any
-data is read (unless it is less than 2 seconds since the last update, in
-which case cached values are returned instead). As a consequence, when
-a once-only alarm triggers, it may take 2 seconds for it to show, and 2
-more seconds for it to disappear.
-
-Monitoring of in9 isn't enabled at lower init levels (<3) because that
-channel measures the battery voltage (Vbat). It is a known fact that
-repeatedly sampling the battery voltage reduces its lifetime. National
-Semiconductor smartly designed their chipset so that in9 is sampled only
-once every 1024 sampling cycles (that is every 34 minutes at the default
-sampling rate), so the effect is attenuated, but still present.
-
-
-Limitations
------------
-
-The datasheets suggests that some values (fan mins, fan dividers)
-shouldn't be changed once the monitoring has started, but we ignore that
-recommendation. We'll reconsider if it actually causes trouble.

-Description
------------
-
-The SiS5595 southbridge has integrated hardware monitor functions. It also
-has an I2C bus, but this driver only supports the hardware monitor. For the
-I2C bus driver see i2c-sis5595.
-
-The SiS5595 implements zero or one temperature sensor, two fan speed
-sensors, four or five voltage sensors, and alarms.
-
-On the first version of the chip, there are four voltage sensors and one
-temperature sensor.
-
-On the second version of the chip, the temperature sensor (temp) and the
-fifth voltage sensor (in4) share a pin which is configurable, but not
-through the driver. Sorry. The driver senses the configuration of the pin,
-which was hopefully set by the BIOS.
-
-Temperatures are measured in degrees Celsius. An alarm is triggered once
-when the max is crossed; it is also triggered when it drops below the min
-value. Measurements are guaranteed between -55 and +125 degrees, with a
-resolution of 1 degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in volts. An
-alarm is triggered if the voltage has crossed a programmable minimum or
-maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. All voltage
-inputs can measure voltages between 0 and 4.08 volts, with a resolution of
-0.016 volt.
-
-In addition to the alarms described above, there is a BTI alarm, which gets
-triggered when an external chip has crossed its limits. Usually, this is
-connected to some LM75-like chip; if at least one crosses its limits, this
-bit gets set.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may already
-have disappeared! Note that in the current implementation, all hardware
-registers are read whenever any data is read (unless it is less than 1.5
-seconds since the last update). This means that you can easily miss
-once-only alarms.
-
-The SiS5595 only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.
-
-Problems
---------
-Some chips refuse to be enabled. We don't know why.
-The driver will recognize this and print a message in dmesg.

-Methods for detecting the HP SIO and reading the thermal data on a dc7100.
-
-The thermal information on the dc7100 is contained in the SIO Hardware Monitor
-(HWM). The information is accessed through an index/data pair. The index/data
-pair is located at the HWM Base Address + 0 and the HWM Base Address + 1. The
-HWM Base address can be obtained from Logical Device 8, registers 0x60 (MSB)
-and 0x61 (LSB). Currently we are using 0x480 for the HWM Base Address and
-0x480 and 0x481 for the index/data pair.
-
-Reading temperature information.
-The temperature information is located in the following registers:
-Temp1		0x25	(Currently, this reflects the CPU temp on all systems).
-Temp2		0x26
-Temp3		0x27
-Temp4		0x80
-
-Programming Example
-The following is an example of how to read the HWM temperature registers:
-MOV	DX,480H
-MOV	AX,25H
-OUT	DX,AL
-MOV	DX,481H
-IN	AL,DX
-
-AL contains the data in hex, the temperature in Celsius is the decimal
-equivalent.
-
-Ex: If AL contains 0x2A, the temperature is 42 degrees C.
-
-Reading tach information.
-The fan speed information is located in the following registers:
-		LSB	MSB
-Tach1		0x28	0x29	(Currently, this reflects the CPU
-				fan speed on all systems).
-Tach2		0x2A	0x2B
-Tach3		0x2C	0x2D
-Tach4		0x2E	0x2F
-
-Important!!!
-Reading the tach LSB locks the tach MSB.
-The LSB Must be read first.
-
-How to convert the tach reading to RPM.
-The tach reading (TCount) is given by: (Tach MSB * 256) + (Tach LSB)
-The SIO counts the number of 90kHz (11.111us) pulses per revolution.
-RPM = 60/(TCount * 11.111us)
-
-Example:
-Reg 0x28 = 0x9B
-Reg 0x29 = 0x08
-
-TCount = 0x89B = 2203
-
-RPM = 60 / (2203 * 11.11111 E-6) = 2451 RPM
-
-Obtaining the SIO version.
-
-CONFIGURATION SEQUENCE
-To program the configuration registers, the following sequence must be followed:
-1. Enter Configuration Mode
-2. Configure the Configuration Registers
-3. Exit Configuration Mode.
-
-Enter Configuration Mode
-To place the chip into the Configuration State The config key (0x55) is written
-to the CONFIG PORT (0x2E).
-
-Configuration Mode
-In configuration mode, the INDEX PORT is located at the CONFIG PORT address and
-the DATA PORT is at INDEX PORT address + 1.
-
-The desired configuration registers are accessed in two steps:
-a.	Write the index of the Logical Device Number Configuration Register
-	(i.e., 0x07) to the INDEX PORT and then write the number of the
-	desired logical device to the DATA PORT.
-
-b.	Write the address of the desired configuration register within the
-	logical device to the INDEX PORT and then write or read the config-
-	uration register through the DATA PORT.
-
-Note: If accessing the Global Configuration Registers, step (a) is not required.
-
-Exit Configuration Mode
-To exit the Configuration State the write 0xAA to the CONFIG PORT (0x2E).
-The chip returns to the RUN State.  (This is important).
-
-Programming Example
-The following is an example of how to read the SIO Device ID located at 0x20
-
-; ENTER CONFIGURATION MODE
-MOV	DX,02EH
-MOV	AX,055H
-OUT	DX,AL
-; GLOBAL CONFIGURATION  REGISTER
-MOV	DX,02EH
-MOV	AL,20H
-OUT	DX,AL
-; READ THE DATA
-MOV	DX,02FH
-IN	AL,DX
-; EXIT CONFIGURATION MODE
-MOV	DX,02EH
-MOV	AX,0AAH
-OUT	DX,AL
-
-The registers of interest for identifying the SIO on the dc7100 are Device ID
-(0x20) and Device Rev  (0x21).
-
-The Device ID will read 0X6F
-The Device Rev currently reads 0x01
-
-Obtaining the HWM Base Address.
-The following is an example of how to read the HWM Base Address located in
-Logical Device 8.
-
-; ENTER CONFIGURATION MODE
-MOV	DX,02EH
-MOV	AX,055H
-OUT	DX,AL
-; CONFIGURE REGISTER CRE0,

-Description
------------
-
-The Standard Microsystems Corporation (SMSC) 47M1xx Super I/O chips
-contain monitoring and PWM control circuitry for two fans.
-
-The 47M15x and 47M192 chips contain a full 'hardware monitoring block'
-in addition to the fan monitoring and control. The hardware monitoring
-block is not supported by the driver.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-PWM values are from 0 to 255.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared! Note that in the current implementation, all
-hardware registers are read whenever any data is read (unless it is less
-than 1.5 seconds since the last update). This means that you can easily
-miss once-only alarms.

-Module Parameters
------------------
-
-force_addr=0xaddr       Set the I/O base address. Useful for Asus A7V boards
-                        that don't set the address in the BIOS. Does not do a
-                        PCI force; the via686a must still be present in lspci.
-                        Don't use this unless the driver complains that the
-                        base address is not set.
-                        Example: 'modprobe via686a force_addr=0x6000'
-
-Description
------------
-
-The driver does not distinguish between the chips and reports
-all as a 686A.
-
-The Via 686a southbridge has integrated hardware monitor functionality.
-It also has an I2C bus, but this driver only supports the hardware monitor.
-For the I2C bus driver, see <file:Documentation/i2c/busses/i2c-viapro>
-
-The Via 686a implements three temperature sensors, two fan rotation speed
-sensors, five voltage sensors and alarms.
-
-Temperatures are measured in degrees Celsius. An alarm is triggered once
-when the Overtemperature Shutdown limit is crossed; it is triggered again
-as soon as it drops below the hysteresis value.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8) to give
-the readings more range or accuracy. Not all RPM values can accurately be
-represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in volts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit. Voltages are internally scalled, so each voltage channel
-has a different resolution and range.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared! Note that in the current implementation, all
-hardware registers are read whenever any data is read (unless it is less
-than 1.5 seconds since the last update). This means that you can easily
-miss once-only alarms.
-
-The driver only updates its values each 1.5 seconds; reading it more often
-will do no harm, but will return 'old' values.

-  Initialize the I2C address of the sensors
-* init: int
-  (default is 1)

-
-Description
------------
-
-This driver implements support for ISA accesses *only* for
-the Winbond W83627HF, W83627THF, W83697HF and W83637HF Super I/O chips.
-We will refer to them collectively as Winbond chips.
-
-This driver supports ISA accesses, which should be more reliable
-than i2c accesses. Also, for Tyan boards which contain both a
-Super I/O chip and a second i2c-only Winbond chip (often a W83782D),
-using this driver will avoid i2c address conflicts and complex
-initialization that were required in the w83781d driver.
-
-If you really want i2c accesses for these Super I/O chips,
-use the w83781d driver. However this is not the preferred method
-now that this ISA driver has been developed.
-
-Technically, the w83627thf does not support a VID reading. However, it's
-possible or even likely that your mainboard maker has routed these signals
-to a specific set of general purpose IO pins (the Asus P4C800-E is one such
-board). The w83627thf driver now interprets these as VID. If the VID on
-your board doesn't work, first see doc/vid in the lm_sensors package. If
-that still doesn't help, email us at lm-sensors@lm-sensors.org.
-
-For further information on this driver see the w83781d driver
-documentation.

-Description
------------
-
-This driver implements support for the Winbond W83781D, W83782D, W83783S,
-W83627HF chips, and the Asus AS99127F chips. We will refer to them
-collectively as W8378* chips.
-
-There is quite some difference between these chips, but they are similar
-enough that it was sensible to put them together in one driver.
-The W83627HF chip is assumed to be identical to the ISA W83782D.
-The Asus chips are similar to an I2C-only W83782D.

-
-Detection of these chips can sometimes be foiled because they can be in
-an internal state that allows no clean access. If you know the address
-of the chip, use a 'force' parameter; this will put them into a more
-well-behaved state first.
-
-The W8378* implements temperature sensors (three on the W83781D and W83782D,
-two on the W83783S), three fan rotation speed sensors, voltage sensors
-(seven on the W83781D, nine on the W83782D and six on the W83783S), VID
-lines, alarms with beep warnings, and some miscellaneous stuff.
-
-Temperatures are measured in degrees Celsius. There is always one main
-temperature sensor, and one (W83783S) or two (W83781D and W83782D) other
-sensors. An alarm is triggered for the main sensor once when the
-Overtemperature Shutdown limit is crossed; it is triggered again as soon as
-it drops below the Hysteresis value. A more useful behavior
-can be found by setting the Hysteresis value to +127 degrees Celsius; in
-this case, alarms are issued during all the time when the actual temperature
-is above the Overtemperature Shutdown value. The driver sets the
-hysteresis value for temp1 to 127 at initialization.
-
-For the other temperature sensor(s), an alarm is triggered when the
-temperature gets higher then the Overtemperature Shutdown value; it stays
-on until the temperature falls below the Hysteresis value. But on the
-W83781D, there is only one alarm that functions for both other sensors!
-Temperatures are guaranteed within a range of -55 to +125 degrees. The
-main temperature sensors has a resolution of 1 degree; the other sensor(s)
-of 0.5 degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4 or 8 for the
-W83781D; 1, 2, 4, 8, 16, 32, 64 or 128 for the others) to give
-the readings more range or accuracy. Not all RPM values can accurately
-be represented, so some rounding is done. With a divider of 2, the lowest
-representable value is around 2600 RPM.
-
-Voltage sensors (also known as IN sensors) report their values in volts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit. Note that minimum in this case always means 'closest to
-zero'; this is important for negative voltage measurements. All voltage
-inputs can measure voltages between 0 and 4.08 volts, with a resolution
-of 0.016 volt.
-
-The VID lines encode the core voltage value: the voltage level your processor
-should work with. This is hardcoded by the mainboard and/or processor itself.
-It is a value in volts. When it is unconnected, you will often find the
-value 3.50 V here.
-
-The W83782D and W83783S temperature conversion machine understands about
-several kinds of temperature probes. You can program the so-called
-beta value in the sensor files. '1' is the PII/Celeron diode, '2' is the
-TN3904 transistor, and 3435 the default thermistor value. Other values
-are (not yet) supported.
-
-In addition to the alarms described above, there is a CHAS alarm on the
-chips which triggers if your computer case is open.
-
-When an alarm goes off, you can be warned by a beeping signal through
-your computer speaker. It is possible to enable all beeping globally,
-or only the beeping for some alarms.
-
-If an alarm triggers, it will remain triggered until the hardware register
-is read at least once. This means that the cause for the alarm may
-already have disappeared! Note that in the current implementation, all
-hardware registers are read whenever any data is read (unless it is less
-than 1.5 seconds since the last update). This means that you can easily
-miss once-only alarms.
-
-The chips only update values each 1.5 seconds; reading them more often
-will do no harm, but will return 'old' values.
-
-AS99127F PROBLEMS
------------------
-The as99127f support was developed without the benefit of a datasheet.
-In most cases it is treated as a w83781d (although revision 2 of the
-AS99127F looks more like a w83782d).
-This support will be BETA until a datasheet is released.
-One user has reported problems with fans stopping
-occasionally.
-
-Note that the individual beep bits are inverted from the other chips.
-The driver now takes care of this so that user-space applications
-don't have to know about it.
-
-Known problems:
-	- Problems with diode/thermistor settings (supported?)
-	- One user reports fans stopping under high server load.
-	- Revision 2 seems to have 2 PWM registers but we don't know
-	  how to handle them. More details below.
-
-These will not be fixed unless we get a datasheet.
-If you have problems, please lobby Asus to release a datasheet.
-Unfortunately several others have without success.
-Please do not send mail to us asking for better as99127f support.
-We have done the best we can without a datasheet.
-Please do not send mail to the author or the sensors group asking for
-a datasheet or ideas on how to convince Asus. We can't help.
-
-
-NOTES:
------
-  783s has no in1 so that in[2-6] are compatible with the 781d/782d.
-
-  783s pin is programmable for -5V or temp1; defaults to -5V,
-       no control in driver so temp1 doesn't work.
-
-  782d and 783s datasheets differ on which is pwm1 and which is pwm2.
-       We chose to follow 782d.
-
-  782d and 783s pin is programmable for fan3 input or pwm2 output;
-       defaults to fan3 input.
-       If pwm2 is enabled (with echo 255 1 > pwm2), then
-       fan3 will report 0.
-
-  782d has pwm1-2 for ISA, pwm1-4 for i2c. (pwm3-4 share pins with
-       the ISA pins)
-
-Data sheet updates:
-------------------
-	- PWM clock registers:
-
-		000: master /  512
-		001: master / 1024
-		010: master / 2048

-Answers from Winbond tech support
----------------------------------
->
-> 1) In the W83781D data sheet section 7.2 last paragraph, it talks about
->    reprogramming the R-T table if the Beta of the thermistor is not
->    3435K. The R-T table is described briefly in section 8.20.

-Asus Clones
------------
-
-We have no datasheets for the Asus clones (AS99127F and ASB100 Bach).
-Here are some very useful information that were given to us by Alex Van
-Kaam about how to detect these chips, and how to read their values. He
-also gives advice for another Asus chipset, the Mozart-2 (which we
-don't support yet). Thanks Alex!
-I reworded some parts and added personal comments.
-
-# Detection:
-
-AS99127F rev.1, AS99127F rev.2 and ASB100:
-- I2C address range: 0x29 - 0x2F
-- If register 0x58 holds 0x31 then we have an Asus (either ASB100 or
-  AS99127F)
-- Which one depends on register 0x4F (manufacturer ID):
-  0x06 or 0x94: ASB100
-  0x12 or 0xC3: AS99127F rev.1
-  0x5C or 0xA3: AS99127F rev.2
-  Note that 0x5CA3 is Winbond's ID (WEC), which let us think Asus get their
-  AS99127F rev.2 direct from Winbond. The other codes mean ATT and DVC,
-  respectively. ATT could stand for Asustek something (although it would be
-  very badly chosen IMHO), I don't know what DVC could stand for. Maybe
-  these codes simply aren't meant to be decoded that way.
-
-Mozart-2:
-- I2C address: 0x77
-- If register 0x58 holds 0x56 or 0x10 then we have a Mozart-2
-- Of the Mozart there are 3 types:
-  0x58=0x56, 0x4E=0x94, 0x4F=0x36: Asus ASM58 Mozart-2
-  0x58=0x56, 0x4E=0x94, 0x4F=0x06: Asus AS2K129R Mozart-2
-  0x58=0x10, 0x4E=0x5C, 0x4F=0xA3: Asus ??? Mozart-2
-  You can handle all 3 the exact same way :)
-
-# Temperature sensors:
-
-ASB100:
-- sensor 1: register 0x27
-- sensor 2 & 3 are the 2 LM75's on the SMBus
-- sensor 4: register 0x17
-Remark: I noticed that on Intel boards sensor 2 is used for the CPU
-  and 4 is ignored/stuck, on AMD boards sensor 4 is the CPU and sensor 2 is
-  either ignored or a socket temperature.
-
-AS99127F (rev.1 and 2 alike):
-- sensor 1: register 0x27
-- sensor 2 & 3 are the 2 LM75's on the SMBus
-Remark: Register 0x5b is suspected to be temperature type selector. Bit 1
-  would control temp1, bit 3 temp2 and bit 5 temp3.
-
-Mozart-2:
-- sensor 1: register 0x27
-- sensor 2: register 0x13
-
-# Fan sensors:
-
-ASB100, AS99127F (rev.1 and 2 alike):
-- 3 fans, identical to the W83781D
-
-Mozart-2:
-- 2 fans only, 1350000/RPM/div
-- fan 1: register 0x28,  divisor on register 0xA1 (bits 4-5)
-- fan 2: register 0x29,  divisor on register 0xA1 (bits 6-7)
-
-# Voltages:
-
-This is where there is a difference between AS99127F rev.1 and 2.
-Remark: The difference is similar to the difference between
-  W83781D and W83782D.
-
-ASB100:
-in0=r(0x20)*0.016
-in1=r(0x21)*0.016
-in2=r(0x22)*0.016
-in3=r(0x23)*0.016*1.68

-in5=r(0x25)*(-0.016)*3.97
-in6=r(0x26)*(-0.016)*1.666
-
-AS99127F rev.1:

-# PWM
-
-Additional info about PWM on the AS99127F (may apply to other Asus
-chips as well) by Jean Delvare as of 2004-04-09:
-
-AS99127F revision 2 seems to have two PWM registers at 0x59 and 0x5A,
-and a temperature sensor type selector at 0x5B (which basically means
-that they swapped registers 0x59 and 0x5B when you compare with Winbond
-chips).
-Revision 1 of the chip also has the temperature sensor type selector at
-0x5B, but PWM registers have no effect.
-
-We don't know exactly how the temperature sensor type selection works.
-Looks like bits 1-0 are for temp1, bits 3-2 for temp2 and bits 5-4 for
-temp3, although it is possible that only the most significant bit matters
-each time. So far, values other than 0 always broke the readings.
-
-PWM registers seem to be split in two parts: bit 7 is a mode selector,
-while the other bits seem to define a value or threshold.
-
-When bit 7 is clear, bits 6-0 seem to hold a threshold value. If the value
-is below a given limit, the fan runs at low speed. If the value is above
-the limit, the fan runs at full speed. We have no clue as to what the limit
-represents. Note that there seem to be some inertia in this mode, speed
-changes may need some time to trigger. Also, an hysteresis mechanism is
-suspected since walking through all the values increasingly and then
-decreasingly led to slightly different limits.
-
-When bit 7 is set, bits 3-0 seem to hold a threshold value, while bits 6-4
-would not be significant. If the value is below a given limit, the fan runs
-at full speed, while if it is above the limit it runs at low speed (so this
-is the contrary of the other mode, in a way). Here again, we don't know
-what the limit is supposed to represent.
-
-One remarkable thing is that the fans would only have two or three
-different speeds (transitional states left apart), not a whole range as
-you usually get with PWM.
-
-As a conclusion, you can write 0x00 or 0x8F to the PWM registers to make
-fans run at low speed, and 0x7F or 0x80 to make them run at full speed.
-
-Please contact us if you can figure out how it is supposed to work. As
-long as we don't know more, the w83781d driver doesn't handle PWM on
-AS99127F chips at all.
-
-Additional info about PWM on the AS99127F rev.1 by Hector Martin:
-
-I've been fiddling around with the (in)famous 0x59 register and
-found out the following values do work as a form of coarse pwm:
-
-0x80 - seems to turn fans off after some time(1-2 minutes)... might be
-some form of auto-fan-control based on temp? hmm (Qfan? this mobo is an
-old ASUS, it isn't marketed as Qfan. Maybe some beta pre-attemp at Qfan
-that was dropped at the BIOS)
-0x81 - off
-0x82 - slightly "on-ner" than off, but my fans do not get to move. I can
-hear the high-pitched PWM sound that motors give off at too-low-pwm.
-0x83 - now they do move. Estimate about 70% speed or so.
-0x84-0x8f - full on
-
-Changing the high nibble doesn't seem to do much except the high bit
-(0x80) must be set for PWM to work, else the current pwm doesn't seem to
-change.
-
-My mobo is an ASUS A7V266-E. This behavior is similar to what I got
-with speedfan under Windows, where 0-15% would be off, 15-2x% (can't
-remember the exact value) would be 70% and higher would be full on.

-Kernel driver w83l785ts
-=======================
-
-Supported chips:
-  * Winbond W83L785TS-S
-    Prefix: 'w83l785ts'
-    Addresses scanned: I2C 0x2e
-    Datasheet: Publicly available at the Winbond USA website
-               http://www.winbond-usa.com/products/winbond_products/pdfs/PCIC/W83L785TS-S.pdf
-
-Authors:
-        Jean Delvare <khali@linux-fr.org>
-
-Description
------------
-
-The W83L785TS-S is a digital temperature sensor. It senses the
-temperature of a single external diode. The high limit is
-theoretically defined as 85 or 100 degrees C through a combination
-of external resistors, so the user cannot change it. Values seen so
-far suggest that the two possible limits are actually 95 and 110
-degrees C. The datasheet is rather poor and obviously inaccurate
-on several points including this one.
-
-All temperature values are given in degrees Celsius. Resolution
-is 1.0 degree. See the datasheet for details.
-
-The w83l785ts driver will not update its values more frequently than
-every other second; reading them more often will do no harm, but will
-return 'old' values.
-
-Known Issues
-------------
-
-On some systems (Asus), the BIOS is known to interfere with the driver
-and cause read errors. The driver will retry a given number of times
-(5 by default) and then give up, returning the old value (or 0 if
-there is no old value). It seems to work well enough so that you should
-not notice anything. Thanks to James Bolt for helping test this feature.

-Naming and data format standards for sysfs files
-------------------------------------------------
-
-The libsensors library offers an interface to the raw sensors data
-through the sysfs interface. See libsensors documentation and source for
-more further information. As of writing this document, libsensors
-(from lm_sensors 2.8.3) is heavily chip-dependant. Adding or updating
-support for any given chip requires modifying the library's code.
-This is because libsensors was written for the procfs interface
-older kernel modules were using, which wasn't standardized enough.
-Recent versions of libsensors (from lm_sensors 2.8.2 and later) have
-support for the sysfs interface, though.
-
-The new sysfs interface was designed to be as chip-independant as
-possible.
-
-Note that motherboards vary widely in the connections to sensor chips.
-There is no standard that ensures, for example, that the second
-temperature sensor is connected to the CPU, or that the second fan is on
-the CPU. Also, some values reported by the chips need some computation
-before they make full sense. For example, most chips can only measure
-voltages between 0 and +4V. Other voltages are scaled back into that
-range using external resistors. Since the values of these resistors
-can change from motherboard to motherboard, the conversions cannot be
-hard coded into the driver and have to be done in user space.
-
-For this reason, even if we aim at a chip-independant libsensors, it will
-still require a configuration file (e.g. /etc/sensors.conf) for proper
-values conversion, labeling of inputs and hiding of unused inputs.
-
-An alternative method that some programs use is to access the sysfs
-files directly. This document briefly describes the standards that the
-drivers follow, so that an application program can scan for entries and
-access this data in a simple and consistent way. That said, such programs
-will have to implement conversion, labeling and hiding of inputs. For
-this reason, it is still not recommended to bypass the library.
-
-If you are developing a userspace application please send us feedback on
-this standard.
-
-Note that this standard isn't completely established yet, so it is subject
-to changes, even important ones. One more reason to use the library instead
-of accessing sysfs files directly.
-
-Each chip gets its own directory in the sysfs /sys/devices tree.  To
-find all sensor chips, it is easier to follow the symlinks from
-/sys/i2c/devices/
-
-All sysfs values are fixed point numbers.  To get the true value of some
-of the values, you should divide by the specified value.
-
-There is only one value per file, unlike the older /proc specification.
-The common scheme for files naming is: <type><number>_<item>. Usual
-types for sensor chips are "in" (voltage), "temp" (temperature) and
-"fan" (fan). Usual items are "input" (measured value), "max" (high
-threshold, "min" (low threshold). Numbering usually starts from 1,
-except for voltages which start from 0 (because most data sheets use
-this). A number is always used for elements that can be present more
-than once, even if there is a single element of the given type on the
-specific chip. Other files do not refer to a specific element, so
-they have a simple name, and no number.
-
-Alarms are direct indications read from the chips. The drivers do NOT
-make comparisons of readings to thresholds. This allows violations
-between readings to be caught and alarmed. The exact definition of an
-alarm (for example, whether a threshold must be met or must be exceeded
-to cause an alarm) is chip-dependent.

-Introduction
-------------
-
-Most mainboards have sensor chips to monitor system health (like temperatures,
-voltages, fans speed). They are often connected through an I2C bus, but some
-are also connected directly through the ISA bus.
-
-The kernel drivers make the data from the sensor chips available in the /sys
-virtual filesystem. Userspace tools are then used to display or set or the
-data in a more friendly manner.
-
-Lm-sensors
-----------
-
-Core set of utilites that will allow you to obtain health information,
-setup monitoring limits etc. You can get them on their homepage
-http://www.lm-sensors.nu/ or as a package from your Linux distribution.
-
-If from website:
-Get lmsensors from project web site. Please note, you need only userspace
-part, so compile with "make user_install" target.
-
-General hints to get things working:
-
-0) get lm-sensors userspace utils
-1) compile all drivers in I2C section as modules in your kernel
-2) run sensors-detect script, it will tell you what modules you need to load.
-3) load them and run "sensors" command, you should see some results.
-4) fix sensors.conf, labels, limits, fan divisors
-5) if any more problems consult FAQ, or documentation
-
-Other utilites
---------------
-
-If you want some graphical indicators of system health look for applications
-like: gkrellm, ksensors, xsensors, wmtemp, wmsensors, wmgtemp, ksysguardd,
-hardware-monitor
-
-If you are server administrator you can try snmpd or mrtgutils.

Subject: [ACPI] S3 Suspend to RAM: interrupt resume fix

Delete PCI Interrupt Link Device .resume method --
it is the device driver's job to request interrupts,
not the Link's job to remember what the devices want.

This addresses the issue of attempting to run
the ACPI interpreter too early in resume, when
interrupts are still disabled.

Subject: [ACPI] Bind PCI devices with ACPI devices

Implement the framework for binding physical devices
with ACPI devices. A physical bus like PCI bus
should create a 'acpi_bus_type', with:

.find_device:
        For device which has parent such as normal PCI devices.

.find_bridge:
        It's for special devices, such as PCI root bridge
	or IDE controller.  Such devices generally haven't a
	parent or ->bus. We use the special method
	to get an ACPI handle.

Uses new field in struct device: firmware_data

Also, kfree(NULL) is legal, so remove some unneeded checks.

An addition to the last ipvs changes that move
update_defense_level/si_meminfo to keventd:

- ip_vs_random_dropentry now runs in process context and should use _bh
  locks to protect from softirqs

- update_defense_level still needs _bh locks after si_meminfo is called,

Subject: [IPV4]: Prevent oops when printing martian source

In some cases, we may be generating packets with a source address that
qualifies as martian. This can happen when we're in the middle of setting
up the network, and netfilter decides to reject a packet with an RST.
The IPv4 routing code would try to print a warning and oops, because
locally generated packets do not have a valid skb->mac.raw pointer
at this point.

Subject: [NET]: add a top-level Networking menu to *config

Create a new top-level menu named "Networking" thus moving
net related options and protocol selection way from the drivers
menu and up on the top-level where they belong.

To implement this all architectures has to source "net/Kconfig" before
drivers/*/Kconfig in their Kconfig file. This change has been
implemented for all architectures.

Device drivers for ordinary NIC's are still to be found
in the Device Drivers section, but Bluetooth, IrDA and ax25
are located with their corresponding menu entries under the new
networking menu item.

From: Robert Moore <robert.moore@intel.com>
Date: Mon, 18 Apr 2005 22:49:35 -0400
Subject: ACPICA 20050408 from Bob Moore

Fixed three cases in the interpreter where an "index"
argument to an ASL function was still (internally) 32
bits instead of the required 64 bits.  This was the Index
argument to the Index, Mid, and Match operators.

The "strupr" function is now permanently local
(acpi_ut_strupr), since this is not a POSIX-defined
function and not present in most kernel-level C
libraries. References to the C library strupr function
have been removed from the headers.

Completed the deployment of static
functions/prototypes. All prototypes with the static
attribute have been moved from the headers to the owning
C file.

ACPICA 20050329 from Bob Moore

An error is now generated if an attempt is made to create
a Buffer Field of length zero (A CreateField with a length
operand of zero.)

The interpreter now issues a warning whenever executable
code at the module level is detected during ACPI table
load. This will give some idea of the prevalence of this
type of code.

Implemented support for references to named objects (other
than control methods) within package objects.

Enhanced package object output for the debug
object. Package objects are now completely dumped, showing
all elements.

Enhanced miscellaneous object output for the debug
object. Any object can now be written to the debug object
(for example, a device object can be written, and the type
of the object will be displayed.)

The "static" qualifier has been added to all local
functions across the core subsystem.

The number of "long" lines (> 80 chars) within the source
has been significantly reduced, by about 1/3.

Cleaned up all header files to ensure that all CA/iASL
functions are prototyped (even static functions) and the
formatting is consistent.

Two new header files have been added, acopcode.h and
acnames.h.

Removed several obsolete functions that were no longer
used.

Subject: [NET]: move config options out to individual protocols

Move the protocol specific config options out to the specific protocols.
With this change net/Kconfig now starts to become readable and serve as a
good basis for further re-structuring.

The menu structure is left almost intact, except that indention is
fixed in most cases. Most visible are the INET changes where several
"depends on INET" are replaced with a single ifdef INET / endif pair.

Several new files were created to accomplish this change - they are
small but serve the purpose that config options are now distributed
out where they belongs.

+	  AppleTalk is the protocol that Apple computers can use to communicate
+	  on a network.  If your Linux box is connected to such a network and you
+	  wish to connect to it, say Y.  You will need to use the netatalk package
+	  so that your Linux box can act as a print and file server for Macs as
+	  well as access AppleTalk printers.  Check out
+	  <http://www.zettabyte.net/netatalk/> on the WWW for details.
+	  EtherTalk is the name used for AppleTalk over Ethernet and the
+	  cheaper and slower LocalTalk is AppleTalk over a proprietary Apple
+	  network using serial links.  EtherTalk and LocalTalk are fully
+	  supported by Linux.
+
+	  General information about how to connect Linux, Windows machines and
+	  Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.  The
+	  NET-3-HOWTO, available from
+	  <http://www.tldp.org/docs.html#howto>, contains valuable
+	  information as well.
+
+	  To compile this driver as a module, choose M here: the module will be
+	  called appletalk. You almost certainly want to compile it as a
+	  module so you can restart your AppleTalk stack without rebooting
+	  your machine. I hear that the GNU boycott of Apple is over, so

+	  When the kernel has several packets to send out over a network

+	  example if some of your network devices are real time devices that
+	  need a certain minimum data flow rate, or if you need to limit the
+	  maximum data flow rate for traffic which matches specified criteria.
+	  This code is considered to be experimental.
+
+	  To administer these schedulers, you'll need the user-level utilities
+	  from the package iproute2+tc at <ftp://ftp.tux.org/pub/net/ip-routing/>.
+	  That package also contains some documentation; for more, check out

Subject: [PATCH] USB ftdi_sio: reduce device id table clutter

ftdi_sio: Use a single usb_device_id table and detect the type of chip
programatically.  The table also flags devices requiring special
initialization.  The patch makes the driver about 10K smaller and makes
it easier to add new device IDs.

Subject: [PATCH] USB ATM: fix line resync logic

We map states 0x00 and 0x10 to the ATM_PHY_SIG_LOST flag.  The current logic fails to
resync the line if we get state 0x10 followed by 0x00, since we only resync the line
when the state is 0x00 and the flag changed.  Doubly fixed by (1) always resyncing the
line when the state is 0x00 even if the state didn't change, and (2) keeping track of
the last state, not just the flag.  We do (2) as well as (1) in order to get better log
messages.

This is a tweaked version of the original patch by Aurelio Arroyo.

Subject: [PATCH] USB: Patch to make usbmon to print control setup packets

Make usbmon to print Setup packets of Control transfers. This is useful
when debugging enumeration issues.

This is a change to the trace format which is not fully compatible.
A parser has to look at the data length word now. If that word is
a character like 's', read setup packet before proceeding with data.
I decided not to bump the API tag for this because not many such
parsers exist at this point.

Subject: [PATCH] USB: add driver for Keyspan Digital Remote

This driver is a basic keypress input driver for the Keyspan Digital
Remote with part number UIA-11.  Currently there is an older remote with
part number UIA-10 which isn't supported by this driver.  Support for
the older UIA-10 could be added but a binary file is required to be
download to the device, and I don't have that file.  I also don't have a
UIA-10 device so I wouldn't be able to test any of the changes.

Subject: [PATCH] USB: coverity: (desc->bitmap)[] overrun fix

The length of the array desc->bitmap is 3, and not 4:

Definitions involved:

In drivers/usb/core/hcd.h

464  	#define bitmap 	DeviceRemovable

In drivers/usb/host/ohci-hub.c

395  		struct usb_hub_descriptor	*desc

In drivers/usb/core/hub.h

130  	struct usb_hub_descriptor {
131  		__u8  bDescLength;
132  		__u8  bDescriptorType;
133  		__u8  bNbrPorts;
134  		__u16 wHubCharacteristics;
135  		__u8  bPwrOn2PwrGood;
136  		__u8  bHubContrCurrent;
137  		    	/* add 1 bit for hub status change; round to bytes */
138  		__u8  DeviceRemovable[(USB_MAXCHILDREN + 1 + 7) / 8];
139  		__u8  PortPwrCtrlMask[(USB_MAXCHILDREN + 1 + 7) / 8];
140  	} __attribute__ ((packed));

In include/linux/usb.h

306  	#define USB_MAXCHILDREN		(16)

This defect was found automatically by Coverity Prevent, a static analysis
tool.

(akpm: this code should be shot.  Field `bitmap' doesn't exist in struct
usb_hub_descriptor.  And this .c file is #included in
drivers/usb/host/ohci-hcd.c, and someone somewhere #defines `bitmap' to
`DeviceRemovable'.

>From a maintainability POV it would be better to memset the whole array
beforehand - I changed the patch to do that)

Subject: [PATCH] USB: add LD devices to hid blacklist

below you will find one patch to hid-core.c, which lets usbhid ignore
our HID devices. It would be nice, if you can apply it.

Subject: [PATCH] USB: gadget/ether build fixes.

I also needed the following on 2.6.13-rc1 without CONFIG_USB_ETH_RNDIS,
symbol fs_status_desc isn't available in that case on PXA255.

This builds both with and without ETH_RNDIS, but I haven't actually
tested either.

PM framework.  This patch removes it from the OMAP OHCI too, removing
the distinction between (previous) PM_SUSPEND_MEM and PM_SUSPEND_DISK
state transitions ... now the only suspend semantics supportable are
what was previously PM_SUSPEND_DISK (4) and is now "PMSG_SUSPEND" (3).

This adds another CDC descriptor type to <linux/usb_cdc.h>; the main claim

This increases the reference count on the usb cdc acm control interface

allows the deferred removal of the tty after the physical device is

Subject: [PATCH] USB: add ldusb driver

The following driver provides complete interrupt-in and interrupt-out
reports (raw data) to a user program. Until now it uses the
HIDIOCGDEVINFO ioctl call, because I don't know better :-(. Perhaps, it
will be ok for you - and I will be happy, if you assign 8 minor numbers.

I have tested it in several environments and it works very well for me.
However, it has a problem with two or more devices at the same hub, if
the two or more devices need 1 ms interrupt-in transfers. Unfortunately
more than one interrupt-in transfer every ms isn't possible (ehci
driver?). This is why the min_interrupt_in_interval and
min_interrupt_out_interval are increased to 2 ms (see the corresponding
module parameters). This way, I can use two devices simultaneously at
the same hub.

Subject: [VLAN]: Fix early vlan adding leads to not functional device

OK, I can see what's happening here. eth0 doesn't detect link-up until
after a few seconds, so when the vlan interface is opened immediately
after eth0 has been opened, it inherits the link-down state. Subsequently
the vlan interface is never properly activated and are thus unable to
transmit any packets.

dev->state bits are not supposed to be manipulated directly. Something
similar is probably needed for the netif_device_present() bit, although
I don't know how this is meant to work for a virtual device.

Subject: [PATCH] __wait_on_freeing_inode fix

This patch fixes queer behavior in __wait_on_freeing_inode().

If I_LOCK was not set it called yield(), effectively busy waiting for the
removal of the inode from the hash.  This change was introduced within
"[PATCH] eliminate inode waitqueue hashtable" Changeset 1.1938.166.16 last
october by wli.

The solution is to restore the old behavior, of unconditionally waiting on
the waitqueue.  It doesn't matter if I_LOCK is not set initally, the task
will go to sleep, and wake up when wake_up_inode() is called from
generic_delete_inode() after removing the inode from the hash chain.

Comment is also updated to better reflect current behavior.

This condition is very hard to trigger normally (simultaneous clear_inode()
with iget()) so probably only heavy stress testing can reveal any change of
behavior.

Subject: [PATCH] bugfix: two read_inode() calls without clear_inode() call
 between

Bug symptoms
~~~~~~~~~~~~
For the same inode VFS calls read_inode() twice and doesn't call
clear_inode() between the two read_inode() invocations.

Bug description
~~~~~~~~~~~~~~~
Suppose we have an inode which has zero reference count but is still in
the inode cache. Suppose kswapd invokes shrink_icache_memory() to free
some RAM. In prune_icache() inodes are removed from i_hash. prune_icache
() is then going to call clear_inode(), but drops the inode_lock
spinlock before this. If in this moment another task calls iget() for an
inode which was just removed from i_hash by prune_icache(), then iget()
invokes read_inode() for this inode, because it is *already removed*
from i_hash.

The end result is: we call iget(#N) then iput(#N); inode #N has zero
i_count now and is in the inode cache; kswapd starts. kswapd removes the
inode #N from i_hash ans is preempted; we call iget(#N) again;
read_inode() is invoked as the result; but we expect clear_inode()
before.

Fix
~~~~~~~
To fix the bug I remove inodes from i_hash later, when clear_inode() is
actually called. I remove them from i_hash under spinlock protection.
Since the i_state is set to I_FREEING, it is safe to do this. The others
will sleep waiting for the inode state change.

I also postpone removing inodes from i_sb_list. It is not compulsory to
do so but I do it for readability reasons. Inodes are added/removed to
the lists together everywhere in the code and there is no point to
change this rule. This is harmless because the only user of i_sb_list
which somehow may interfere with me (invalidate_list()) is excluded by
the iprune_sem mutex.

The same race is possible in invalidate_list() so I do the same for it.

If the CardBus windows were pre-configured and the CardBus bridge is behind a
transparent PCI-PCI bridge, pci_find_parent_resource() might return a
different resource than the real parent if it is called before the window is
determined.  Therefore, move that call around.

Also fix return of value in void function.

Subject: [PATCH] mm/filemap_xip.c compilation fix

mm/filemap_xip.c: In function `__xip_unmap':
mm/filemap_xip.c:194: request for member `pte' in something not a structure or union

Apparently pte_pfn() takes a pte_t, not a pointer to a pte_t.  From looking
at asm/page.h, it seems to be the same on ia32 or ppc (iff
STRICT_MM_TYPECHECKS is enabled, which is disabled by default on ppc).

Subject: [PATCH] uml: tlb flushing fix

This patch fixes a fairly serious tlb flushing bug that makes aio use under
uml very unreliable -- SEGVs, Oops and panic()s occur as a result of stale
tlb entires being used by uml when aio switches mms due to the fact that
uml does not implement the activate_mm() hook.  This patch introduces a
simple but correct approach (read: hammer) for implementing activate_mm()
in uml by doing a force_flush_all() if the new mm is different from old.
With this patch in place, uml is able to succeed at the aio test case that
was randomly faulting for me before.

This patch fixes some minor bugs introduced by the previous patch (remove
old syscalls).  Both patches remove the obsolete syscalls.  The changes in
this patch were suggested by Arnd Bergmann.  The vmlinux.lds.S changes are
required for the latest gcc/binutils.

Subject: [PATCH] reset real_timer target on exec leader change

When a noninitial thread does exec, it becomes the new group leader.  If
there is a ITIMER_REAL timer running, it points at the old group leader and
when it fires it can follow a stale pointer.  The timer data needs to be
reset to point at the exec'ing thread that is becoming the group leader.
This has to synchronize with any concurrent firing of the timer to make
sure that it_real_fn can never run when the data points to a thread that
might have been reaped already.

Subject: [PATCH] cdev: cdev_put oops

While fixing an oops in the st driver in a dirty release path, I
encountered an oops in cdev_put for cdevs allocated using cdev_alloc.  If
cdev_del is called when the cdev kobject still has an open user, when the
last cdev_put is called, the cdev_put will call kobject_put, which will end
up ultimately releasing the cdev in cdev_dynamic_release.  Patch fixes the
oops by preventing cdev_put from accessing freed memory.

ksysfs crash_notes attribute handling was left under CONFIG_KEXEC for
simplicity although it is not strictly kexec related.

We provide here a dummy definition for crash_notes on ppc.

Subject: [PATCH] dvb: fix kobject names (no slashes)

device names - removed it, now it works!

Same for ttusb-budget.

From 41ef7c1ed48cb273c7b7a9ffd48a262a22f84483 Mon Sep 17 00:00:00 2001
From: Mauro Carvalho Chehab <mchehab@brturbo.com.br>
Date: Tue, 12 Jul 2005 13:58:44 -0700
Subject: [PATCH] v4l: CX88 Update

- Removed unused structures.
- Removed BTTV version check.
- Some debug structs moved to their own .c file and converted to static
- Comment changed to express better when attach_inform is running
- set_freq removed from set_mode at tuner-core.c.
- I2C cleanups and converged to a basic reference structure.
- Rename tuner structures fields.
- It calls VIDIOC_G_FREQUENCY to get tuner freq from tuner.
- added missing contrast offset value, set to 0.
- Let Kconfig decide whether to include frontend-specific code.

Subject: [PATCH] v4l: SAA7134 hybrid DVB

- Add new Typhoon DVB-T Cardbus.
- DVB-T support for MD7134 cardbus and the PCI variants
- initial DVB-T support for Lifeview Flydvb-t duo
- DVB-T support for Philips TOUGH reference design
- Don't turn off the xtal output of tda8274/75 in sleep mode
- Let Kconfig decide whether to include frontend-specific code in saa7134-dvb.
- Removed unused structures.

From f7ce3cc67052de63a29bad90110640b687d12058 Mon Sep 17 00:00:00 2001
From: Mauro Carvalho Chehab <mchehab@brturbo.com.br>
Date: Tue, 12 Jul 2005 13:58:55 -0700
Subject: [PATCH] v4l: I2C Tuner

- Fixed a trouble on tuner-core that generates erros on computers with more
  than one TV card.
- Rename tuner structures fields.
- Tail spaces removed.
- I2C cleanups and converged to a basic reference structure.
- Removed unused structures.
- Fix setting frequency on tda8290.
- Added code for TEA5767 autodetection.
- Standby mode support implemented. It is used to disable
  a non used tuner. Currenlty implemented on tea5767.
- New macro: set_type disables other tuner when changing mode.
- Some cleanups.
- Use 50 kHz step when tunning radio for most tuners to improve precision.

Subject: [PATCH] device-mapper multipath: Avoid possible suspension deadlock

To avoid deadlock when suspending a multipath device after all its paths have
failed, stop queueing any I/O that is about to fail *before* calling
freeze_bdev instead of after.

Instead of setting a multipath 'suspended' flag which would have to be reset
if an error occurs during the process, save the previous queueing state and
leave userspace to restore if it wishes.

Subject: [PATCH] device-mapper multipath: Fix pg initialisation races

Prevent more than one priority group initialisation function from being
outstanding at once.  Otherwise the completion functions interfere with each
other.  Also, reloading the table could reference a freed pointer.

Only reset queue_io in pg_init_complete if another pg_init isn't required.
Skip process_queued_ios if the queue is empty so that we only trigger a
pg_init if there's I/O.

Subject: [PATCH] reiserfs: fix up case where indent misreads the code

 indent(1) doesn't know how to handle the "do not compile" error. It results
 in the item_ops array declaration being indented a tab stop in when it should
 not be. This patch replaces it with a #error that describes why it's failing.

Subject: reiserfs: run scripts/Lindent on reiserfs code

This was a pure indentation change, using:

	scripts/Lindent fs/reiserfs/*.c include/linux/reiserfs_*.h

to make reiserfs match the regular Linux indentation style.  As Jeff
Mahoney <jeffm@suse.com> writes:

 The ReiserFS code is a mix of a number of different coding styles, sometimes
 different even from line-to-line. Since the code has been relatively stable
 for quite some time and there are few outstanding patches to be applied, it
 is time to reformat the code to conform to the Linux style standard outlined
 in Documentation/CodingStyle.

 This patch contains the result of running scripts/Lindent against
 fs/reiserfs/*.c and include/linux/reiserfs_*.h. There are places where the
 code can be made to look better, but I'd rather keep those patches separate
 so that there isn't a subtle by-hand hand accident in the middle of a huge
 patch. To be clear: This patch is reformatting *only*.

 A number of patches may follow that continue to make the code more consistent
 with the Linux coding style.

 Hans wasn't particularly enthusiastic about these patches, but said he
 wouldn't really oppose them either.

Subject: [PATCH] inotify

inotify is intended to correct the deficiencies of dnotify, particularly
its inability to scale and its terrible user interface:

        * dnotify requires the opening of one fd per each directory
          that you intend to watch. This quickly results in too many
          open files and pins removable media, preventing unmount.
        * dnotify is directory-based. You only learn about changes to
          directories. Sure, a change to a file in a directory affects
          the directory, but you are then forced to keep a cache of
          stat structures.
        * dnotify's interface to user-space is awful.  Signals?

inotify provides a more usable, simple, powerful solution to file change
notification:

        * inotify's interface is a system call that returns a fd, not SIGIO.
	  You get a single fd, which is select()-able.
        * inotify has an event that says "the filesystem that the item
          you were watching is on was unmounted."
        * inotify can watch directories or files.

Inotify is currently used by Beagle (a desktop search infrastructure),
Gamin (a FAM replacement), and other projects.

+				    inotify
+	     a powerful yet simple file change notification system
+
+
+
+Document started 15 Mar 2005 by Robert Love <rml@novell.com>
+
+(i) User Interface
+
+Inotify is controlled by a set of three sys calls 
+
+First step in using inotify is to initialise an inotify instance
+
+	int fd = inotify_init ();
+
+Change events are managed by "watches".  A watch is an (object,mask) pair where
+the object is a file or directory and the mask is a bit mask of one or more
+inotify events that the application wishes to receive.  See <linux/inotify.h>
+for valid events.  A watch is referenced by a watch descriptor, or wd.
+
+Watches are added via a path to the file.
+
+Watches on a directory will return events on any files inside of the directory.
+
+Adding a watch is simple,
+
+	int wd = inotify_add_watch (fd, path, mask);
+
+You can add a large number of files via something like
+
+	for each file to watch {
+		int wd = inotify_add_watch (fd, file, mask);
+	}
+
+You can update an existing watch in the same manner, by passing in a new mask.
+
+An existing watch is removed via the INOTIFY_IGNORE ioctl, for example
+
+	inotify_rm_watch (fd, wd);
+
+Events are provided in the form of an inotify_event structure that is read(2)
+from a inotify instance fd.  The filename is of dynamic length and follows the 
+struct. It is of size len.  The filename is padded with null bytes to ensure 
+proper alignment.  This padding is reflected in len.
+
+You can slurp multiple events by passing a large buffer, for example
+
+	size_t len = read (fd, buf, BUF_LEN);
+
+Will return as many events as are available and fit in BUF_LEN.
+
+each inotify instance fd is also select()- and poll()-able.
+
+You can find the size of the current event queue via the FIONREAD ioctl.
+
+All watches are destroyed and cleaned up on close.
+
+
+(ii) Internal Kernel Implementation
+
+Each open inotify instance is associated with an inotify_device structure.
+
+Each watch is associated with an inotify_watch structure.  Watches are chained
+off of each associated device and each associated inode.
+
+See fs/inotify.c for the locking and lifetime rules.
+
+
+(iii) Rationale
+
+Q: What is the design decision behind not tying the watch to the open fd of
+   the watched object?
+
+A: Watches are associated with an open inotify device, not an open file.
+   This solves the primary problem with dnotify: keeping the file open pins
+   the file and thus, worse, pins the mount.  Dnotify is therefore infeasible
+   for use on a desktop system with removable media as the media cannot be
+   unmounted.
+
+Q: What is the design decision behind using an-fd-per-device as opposed to
+   an fd-per-watch?
+
+A: An fd-per-watch quickly consumes more file descriptors than are allowed,
+   more fd's than are feasible to manage, and more fd's than are optimally
+   select()-able.  Yes, root can bump the per-process fd limit and yes, users
+   can use epoll, but requiring both is a silly and extraneous requirement.
+   A watch consumes less memory than an open file, separating the number
+   spaces is thus sensible.  The current design is what user-space developers
+   want: Users initialize inotify, once, and add n watches, requiring but one fd
+   and no twiddling with fd limits.  Initializing an inotify instance two
+   thousand times is silly.  If we can implement user-space's preferences 
+   cleanly--and we can, the idr layer makes stuff like this trivial--then we 
+   should.
+
+   There are other good arguments.  With a single fd, there is a single
+   item to block on, which is mapped to a single queue of events.  The single
+   fd returns all watch events and also any potential out-of-band data.  If
+   every fd was a separate watch,
+
+   - There would be no way to get event ordering.  Events on file foo and
+     file bar would pop poll() on both fd's, but there would be no way to tell
+     which happened first.  A single queue trivially gives you ordering.  Such
+     ordering is crucial to existing applications such as Beagle.  Imagine
+     "mv a b ; mv b a" events without ordering.
+
+   - We'd have to maintain n fd's and n internal queues with state,
+     versus just one.  It is a lot messier in the kernel.  A single, linear
+     queue is the data structure that makes sense.
+
+   - User-space developers prefer the current API.  The Beagle guys, for
+     example, love it.  Trust me, I asked.  It is not a surprise: Who'd want
+     to manage and block on 1000 fd's via select?
+
+   - You'd have to manage the fd's, as an example: Call close() when you
+     received a delete event.
+
+   - No way to get out of band data.
+
+   - 1024 is still too low.  ;-)
+
+   When you talk about designing a file change notification system that
+   scales to 1000s of directories, juggling 1000s of fd's just does not seem
+   the right interface.  It is too heavy.
+
+Q: Why the system call approach?
+
+A: The poor user-space interface is the second biggest problem with dnotify.
+   Signals are a terrible, terrible interface for file notification.  Or for
+   anything, for that matter.  The ideal solution, from all perspectives, is a
+   file descriptor-based one that allows basic file I/O and poll/select.
+   Obtaining the fd and managing the watches could have been done either via a
+   device file or a family of new system calls.  We decided to implement a
+   family of system calls because that is the preffered approach for new kernel
+   features and it means our user interface requirements.
+
+   Additionally, it _is_ possible to  more than one instance  and
+   juggle more than one queue and thus more than one associated fd.
