If we can't find a replacement in the software table, we accidently leave a duplicate in the HW table. This patch ensures that duplicate is marked as not valid. What we should do is find the replacement in the software table, before we find a victim in the HW table - but its too late in the release cycle to do that much restructuring of this code. Rather that duplicate code, connect Hardware Errors (irq5) into trap_c, so user space processes get killed properly. The rest of irq_panic() can be moved into traps.c (later) There is still a small corner case that causes problems when a pheriperal interrupt goes off a single cycle before a user space hardware error. This causes a kernel panic, rather than the user space process being killed. But, this checkin makes things work in 99.9% of the cases, and is a vast improvement from what is there today (which fails 100% of the time).

An easy way to reproduce: 1) mount //server/share1 2) watch /proc/fs/cifs/DebugData for the share to go DISCONNECTED 3) mount //server/share2 with same creds as in step 1. The second mount will fail because CIFSTCon returned -EAGAIN. If you do an operation in share1 and then reattempt the mount it will work (since the session is reestablished). The following patch fixes this by having cifs_mount check the status of the session when it picks an existing session and calling cifs_setup_session on it again if it's in need of reconnection.

When such no-write page goes to metapage_writepage(), the `relic' PAGECACHE_TAG_DIRTY tag should be cleared, to prevent pdflush from repeatedly trying to sync them.

It is based off of RFC 3686. Please note: 1. CTR turns a block cipher into a stream cipher. Encryption is done in blocks, however the last block may be a partial block. A "counter block" is encrypted, creating a keystream that is xor'ed with the plaintext. The counter portion of the counter block is incremented after each block of plaintext is encrypted. Decryption is performed in same manner. 2. The CTR counterblock is composed of, nonce + IV + counter The size of the counterblock is equivalent to the blocksize of the cipher. sizeof(nonce) + sizeof(IV) + sizeof(counter) = blocksize The CTR template requires the name of the cipher algorithm, the sizeof the nonce, and the sizeof the iv. ctr(cipher,sizeof_nonce,sizeof_iv) So for example, ctr(aes,4,8) specifies the counterblock will be composed of 4 bytes from a nonce, 8 bytes from the iv, and 4 bytes for counter since aes has a blocksize of 16 bytes. 3. The counter portion of the counter block is stored in big endian for conformance to rfc 3686.

Remove unused macros (COPY4WORD, SWAP4WORD, XOR4WORD[2]) Drop SUBL(), SUBR() macros which only obscure things. Same for CAMELLIA_SP1110() macro and KEY_TABLE_TYPE typedef. Remove useless comments: /* encryption */ -- well it's obvious enough already! void camellia_encrypt128(...) Combine swap with copying at the beginning/end of encrypt/decrypt.

-- cgit v0.10.2 From 3a5e5f8108fe440657e8041afd973d2fe72180bb Mon Sep 17 00:00:00 2001 From: Denys Vlasenko Date: Tue, 6 Nov 2007 22:05:36 +0800 Subject: [CRYPTO] camellia: Code cleanup Rename some macros to shorter names: CAMELLIA_RR8 -> ROR8, making it easier to understand that it is just a right rotation, nothing camellia-specific in it. CAMELLIA_SUBKEY_L() -> SUBKEY_L() - just shorter. Move be32 <-> cpu conversions out of en/decrypt128/256 and into camellia_en/decrypt - no reason to have that code duplicated twice.

The template is now ctr(algo,noncesize,ivsize,countersize). For example, ctr(aes,4,8,4) indicates the counterblock will be composed of a salt/nonce that is 4 bytes, an iv that is 8 bytes and the counter is 4 bytes. When noncesize + ivsize < blocksize, CTR initializes the last block - ivsize - noncesize portion of the block to zero. Otherwise the counter block is composed of the IV (and nonce if necessary). If noncesize + ivsize == blocksize, then this indicates that user is passing in entire counterblock. Thus countersize indicates the amount of bytes in counterblock to use as the counter for incrementing. CTR will increment counter portion by 1, and begin encryption with that value. Note that CTR assumes the counter portion of the block that will be incremented is stored in big endian.

This ressources can be shared by other AES implementations (aes-x86_64 for instance). The decryption key has been turned around (deckey[0] is the first piece of the key instead of deckey[keylen+20]).

HMAC-SHA-224 as described in RFC4231 is then supported through the hmac interface. Patch includes test vectors for SHA-224 and HMAC-SHA-224. SHA-224 chould be chosen as a hash algorithm when 112 bits of security strength is required. Patch generated against the 2.6.24-rc1 kernel and tested against 2.6.24-rc1-git14 which includes fix for scatter gather implementation for HMAC.

This patch forces HIFN driver to invoke crypto request callbacks from tasklet (softirq context) instead of hardirq context, since network stack expects it to be called from bottom halves. It is done by simply scheduling callback invocation via dedicated tasklet. Workqueue solution was dropped because of tooo slow rescheduling performance (7 times slower than tasklet, for mode details one can check this link: http://tservice.net.ru/~s0mbre/blog/devel/other/2007_11_09.html).

This is suboptimal because ablkcipher refers to two things. On the one hand it refers to the top-level ablkcipher interface with requests. On the other hand it refers to and algorithm type underneath. As it is you cannot request a synchronous block cipher algorithm with the ablkcipher interface on top. This is a problem because we want to be able to eventually phase out the blkcipher top-level interface. This patch fixes this by making ABLKCIPHER its own type, just as we have distinct types for HASH and DIGEST. The type it associated with the algorithm implementation only. Which top-level interface is used for synchronous block ciphers is then determined by the mask that's used. If it's a specific mask then the old blkcipher interface is given, otherwise we go with the new ablkcipher interface.

According to a comment in the BSD source, this is true for the external clock on almost all every board. - writes to a reserved bit - doesn't follow the initialization procedure specified in chapter 6.11.1 of the HIFN hardware users guide - doesn't allow to use the PCI clock This patch adds a module parameter to specify the reference clock (pci or external) and its frequency and uses that to calculate the optimum multiplier to reach the maximal speed. By default it uses the external clock and assumes a speed of 66MHz, which effectively halfs the frequency currently used.

In fact, all of our block ciphers obey this rule. If we require this then CBC can be optimised to avoid an expensive divide on in-place decryption. I've also changed the saving of the first IV in the in-place decryption case to the last IV because that lets us use walk->iv (which is already aligned) for the xor operation where alignment is required.

This further reduces source and object code size at the cost of two brances in key setup code.

CTR is supposed to return any unused partial block in that case to the walker. This patch fixes this by doing exactly that, returning partial blocks to the walker unless we received less than a block-worth of data to start with. This also allows us to optimise the bulk of the processing since we no longer have to worry about partial blocks until the very end.

The name blkcipher has always been much of a misnomer since it supports stream ciphers too. This patch adds the function crypto_grab_skcipher as a new way of getting an ablkcipher spawn. The problem is that previously we did this in two steps, first getting the algorithm and then calling crypto_init_spawn. This meant that each spawn user had to be aware of what type and mask to use for these two steps. This is difficult and also presents a problem when the type/mask changes as they're about to be for IV generators. The new interface does both steps together just like crypto_alloc_ablkcipher. As a side-effect this also allows us to be stronger on type enforcement for spawns. For now this is only done for ablkcipher but it's trivial to extend for other types. This patch also moves the type/mask logic for skcipher into the helpers crypto_skcipher_type and crypto_skcipher_mask. Finally this patch introduces the function crypto_require_sync to determine whether the user is specifically requesting a sync algorithm.

For example, CBC can use a simple randomly generated IV while modes such as CTR must use an IV generation mechanisms that give a stronger guarantee on the lack of collisions. Furthermore, disk encryption modes have their own IV generation algorithms. Up until now IV generation has been left to the users of the symmetric key cipher API. This is inconvenient as the number of block cipher modes increase because the user needs to be aware of which mode is supposed to be paired with which IV generation algorithm. Therefore it makes sense to integrate the IV generation into the crypto API. This patch takes the first step in that direction by creating two new ablkcipher operations, givencrypt and givdecrypt that generates an IV before performing the actual encryption or decryption. The operations are currently not exposed to the user. That will be done once the underlying functionality has actually been implemented. It also creates the underlying givcipher type. Algorithms that directly generate IVs would use it instead of ablkcipher. All other algorithms (including all existing ones) would generate a givcipher algorithm upon registration. This givcipher algorithm will be constructed from the geniv string that's stored in every algorithm. That string will locate a template which is instantiated by the blkcipher/ablkcipher algorithm in question to give a givcipher algorithm.

It simply starts out with a random IV, then uses the last block of each encrypted packet's cipher text as the IV for the next packet. It can only be used by synchronous ciphers since we have to make sure that we don't start the encryption of the next packet until the last one has completed. It does have the advantage of using very little CPU time since it doesn't have to generate anything at all.

The rationale is identical to that of the skcipher givcrypt operations, i.e., sometimes only the algorithm knows how the IV should be generated. A new request type aead_givcrypt_request is added which contains an embedded aead_request structure with two new elements to support this operation. The new elements are seq and giv. The seq field should contain a strictly increasing 64-bit integer which may be used by certain IV generators as an input value. The giv field will be used to store the generated IV.

The test vectors are from rfc 3610. There are about 10 more test vectors in RFC 3610 and 4 or 5 more in NIST. I can add these as time permits. I also needed to set authsize. CCM has a prerequisite of authsize.

backwards compatibility. Previously the null algorithm when used by IPsec copied the data byte by byte. This new algorithm optimises that to a straight memcpy which lets us better measure inherent overheads in our IPsec code.

If a synchronous algorithm is requested then we behave as before. This should improve IPsec performance on SMP when two CPUs attempt to transmit over the same SA. Currently one of them will spin doing nothing waiting for the other CPU to finish its encryption. This patch makes it postpone the request and get on with other work. If only one CPU is transmitting for a given SA, then we will process the request synchronously as before.

Create a file "update_bios" in sysfs to allow user to update bios from user space. 2. The BIOS image file can be downloaded from web site "http://www.adaptec.com/en-US/downloads/bios_fw/bios_fw_ver?productId=SAS-48300&dn=Adaptec+Serial+Attached+SCSI+48300" and copy the BIOS image into /lib/firmware folder. 3. The aic994xx will accept "update bios_file" and "verify bios_file" commands to perform update and verify BIOS image . For example: Type "echo "update asc483c01.ufi" > /sys/devices/.../update_bios" to update BIOS image from /lib/firmware/as483c01.ufi file into HBA's flash memory. Type "echo "verify asc483c01.ufi" > /sys/devices/.../update_bios" to verify BIOS image between /lib/firmware/asc48c01.ufi file and HBA's flash memory. 4. Type "cat /sys/devices/.../update_bios" to view the status or result of updating BIOS.

Some of our customers have requested the option to be able to reset the adapter under adverse adapter failure, we even had a few defects reported here considering it a regression that the Adapter could not be reset. This patch addresses this dichotomy. The user can force the adapter to be reset if it supports the IOP_RESET_ALWAYS command, in cases where the adapter has been programmed to ignore the reset, by setting the aacraid.check_reset parameter to a value of -1. The driver will not reset an Adapter that does not support the reset command(s). This patch also fixes and cleans up some of the logic associated with resetting the adapter.

SCSI commands + are 6, 10, 12, or 16 bytes long, often followed by an associated data + payload. + + + SCSI commands can be transported over just about any kind of bus, and + are the default protocol for storage devices attached to USB, SATA, + SAS, Fibre Channel, FireWire, and ATAPI devices. SCSI packets are + also commonly exchanged over Infiniband, + I20, TCP/IP + (iSCSI), even + Parallel + ports. + + + + Design of the Linux SCSI subsystem + + The SCSI subsystem uses a three layer design, with upper, mid, and low + layers. Every operation involving the SCSI subsystem (such as reading + a sector from a disk) uses one driver at each of the 3 levels: one + upper layer driver, one lower layer driver, and the scsi midlayer. + + + The SCSI upper layer provides the interface between userspace and the + kernel, in the form of block and char device nodes for I/O and + ioctl(). The SCSI lower layer contains drivers for specific hardware + devices. + + + In between is the SCSI mid-layer, analogous to a network routing + layer such as the IPv4 stack. The SCSI mid-layer routes a packet + based data protocol between the upper layer's /dev nodes and the + corresponding devices in the lower layer. It manages command queues, + provides error handling and power management functions, and responds + to ioctl() requests. + + + + + + SCSI upper layer + + The upper layer supports the user-kernel interface by providing + device nodes. + + + sd (SCSI Disk) + sd (sd_mod.o) + + + + sr (SCSI CD-ROM) + sr (sr_mod.o) + + + st (SCSI Tape) + st (st.o) + + + sg (SCSI Generic) + sg (sg.o) + + + ch (SCSI Media Changer) + ch (ch.c) + + + + + SCSI mid layer + + + SCSI midlayer implementation + + include/scsi/scsi_device.h + + +!Iinclude/scsi/scsi_device.h + + + + drivers/scsi/scsi.c + Main file for the scsi midlayer. +!Edrivers/scsi/scsi.c + + + drivers/scsi/scsicam.c + + SCSI + Common Access Method support functions, for use with + HDIO_GETGEO, etc. + +!Edrivers/scsi/scsicam.c + + + drivers/scsi/scsi_error.c + Common SCSI error/timeout handling routines. +!Edrivers/scsi/scsi_error.c + + + drivers/scsi/scsi_devinfo.c + + Manage scsi_dev_info_list, which tracks blacklisted and whitelisted + devices. + +!Idrivers/scsi/scsi_devinfo.c + + + drivers/scsi/scsi_ioctl.c + + Handle ioctl() calls for scsi devices. + +!Edrivers/scsi/scsi_ioctl.c + + + drivers/scsi/scsi_lib.c + + SCSI queuing library. + +!Edrivers/scsi/scsi_lib.c + + + drivers/scsi/scsi_lib_dma.c + + SCSI library functions depending on DMA + (map and unmap scatter-gather lists). + +!Edrivers/scsi/scsi_lib_dma.c + + + drivers/scsi/scsi_module.c + + The file drivers/scsi/scsi_module.c contains legacy support for + old-style host templates.

This is easy to demonstrate by replacing pci_try_set_mwi() in the patch below with pci_clear_mwi(). My benchmarks show the following: MWI disabled: 15 MB/s write, 330 MB/s read MWI enabled: 240 MB/s write, 330 MB/s read Most motherboards will enable MWI without the driver having to set it explicitly, so most people probably wouldn't encounter this problem. For the few motherboards that don't enable it, this patch could give a 16x performance improvement for writing. This issue does not seem to affect the 9550SX controller, but the patch doesn't hurt it either. I haven't tested any of the other 3ware controllers.

The inquiry string of the tape drive may be different from that of the medium changer. In order for single_lun to be effective, every scsi_device under a given scsi_target must have it set. This means that there needs to be a blacklist entry for BOTH the medium changer AND the tape drive, which is impractical because some medium changers may be paired with a variety of different tape drive models. It makes more sense to put the single_lun flag in scsi_target instead of scsi_device, which causes every device at a given target ID to inherit the single_lun flag from one LUN. This makes it possible to blacklist just the medium changer and not the tape drive.

In ibmvscsi_eh_abort_handler() the loop includes the search of the event list. The lock on the hostdata is dropped while waiting to try again after failing ibmvscsi_send_srp_event. The event could have been purged if a login was in progress when the function was called. In ibmvscsi_eh_device_reset_handler() the loop includes the call to get_event_struct() because a failing call to ibmvscsi_send_srp_event() will have freed the event struct.

The adapters are still capable of 64 bit ScatterGather I/O commands, but these two can not be mixed. This problem was exacerbated by the introduction of the SCSI Generic access to the DASD physical devices. The fix for users before this patch is applied is aacraid.dacmode=3D0 on the kernel command line to disable 64 bit I/O. The enclosed patch introduces a new adapter quirk and tries to limp along by enabling pass-through in situations where memory is 32 bit addressable on 64 bit machines, or disable the pass-through functions altogether. I expect that the check for 32 bit addressable memory to be controversial in that it can be incorrect in non-Dell non-Intel systems that PERC would never be installed under, the alternative is to disable pass-through in all cases which could be reported as another regression. Pass-through is used for SCSI Generic access to the physical devices, or for the management applications to properly function. In systems where this patch has disabled pass-through because it is unsupportable in combination with I/O performance, the user can choose to enable pass-through by turning off dacmode (aacraid.dacmode=3D0) or limiting the discovered kernel memory (mem=3D4G) with an associated loss in runtime performance. If we chose instead to turn off 64 bit dacmode for the adapters with this quirk, then this would be reported as another regression.

Here I add a hdr_max field pertaining to that storage, and an hdr_len that accumulates the current use of the pdu-header. - Add an iscsi_next_hdr() inline which returns the next free space to write new Header at. Also iscsi_next_hdr() is used to retrieve the address at which to write the header-digest. - Add iscsi_add_hdr(length). What the user do is calls iscsi_next_hdr() for address of the new header, than calls iscsi_add_hdr(length) with the size of the new header. iscsi_add_hdr() will check if space is available and update to the new size. length must be padded according to standard. - Add 2 padding inline helpers thanks to Olaf. Current patch does not use them but Following patches will. Also moved definition of ISCSI_PAD_LEN to iscsi_proto.h which had PAD_WORD_LEN that was never used anywhere. - Let iscsi_prep_scsi_cmd_pdu() signal an Error return since now it is possible that it will fail. - I was tired of yet again writing a "this is a digest" comment next to sizeof(__u32) so I defined a new ISCSI_DIGEST_SIZE. Now I don't need any comments. Changed all places that used sizeof(__u32) or "4" in connection to a digest. iscsi_tcp specific code - At struct iscsi_tcp_cmd_task allocate maximum space allowed in standard for all headers following the iscsi_cmd header. and mark it so in iscsi_tcp_session_create() - At iscsi_send_cmd_hdr() retrieve the correct headers size and write header digest at iscsi_next_hdr().

This patch simplifies the code a little by using iscsi_pool_free to tear down the pool in case of an error. iscsi_pool_init also returns a copy of the item array to the caller. Not all callers use this array, so we make it optional. Instead of allocating a second array and return that, allocate just one array, of twice the size. Update users of iscsi_pool_{init,free} This patch drops the (now useless) second argument to iscsi_pool_free, and updates all callers.

At this time iscsid cannot be running, so the target will drop the session and the boot or shutdown will hang.

This means that an ATA8 TCG drive is going to trigger 32bit I/O on some systems which will be funny. Anyway we need to sort this out ready for ATA8 so: - Reorder the ata.h header a bit so the ata_version function occurs early in it - Make dword_io check the ATA version - Add an ATA8 version checking TCG presence test While we are at it the current drafts have a flaw where it may not be possible to disable TCG features at boot (and opt out of the trusted model) as TCG intends because it relies on presence of a different optional feature (DCS). Handle this in software by refusing the TCG commands if libata.allow_tpm is not set. (We must make it possible as some environments such as proprietary VDR devices will doubtless want to use it to lock up content) Finally as with CPRM print a warning so that the user knows they may not be able to full access and use the device.

This isn't correct for the following cases. * ich6/7m's which only implement P0 and P2 (0xf works fine tho) * ich8/9's which have six ports and needs 0x3f to enable all ports This patch updates PCS programming such that... * port_map determined by ahci_save_initial_config() is OR'd instead of 0xf * PCS is updated only if necessary (there are turned off enable bits) port_map is determined from PORTS_IMPL PCI register which is implemented as write or write-once register. If the register isn't programmed, ahci automatically generates it from number of ports, which is good enough for PCS programming. ICH6/7M are probably the only ones where non-contiguous enable bits are necessary && PORTS_IMPL isn't programmed properly but they're proven to work reliably with 0xf anyway.

Till now, nv_cable_detect() relied on peeking BIOS and ACPI configurations to upgrade to 80C but this often results in misdetection of 40C cable as 80C. Also, the original implementation was broken in that by the time BIOS configuration is read it has already been cleared by programming PIO0 during reset. This patch reimplements NV mode selection such that... * BIOS configuration value is stored during driver attach and restored on detach. * Cable type is fixed to ATA_CBL_PATA_IGN and mode selection is soley done by nv_mode_filter() which peeks both BIOS and ACPI configurations and filter accordingly.

This patch makes qc->nbytes include any extra buffers setup by libata core layer and guaranteed to be aligned on 4 byte boundary. This value is to be used to program the host controller. As this represents the actual length of buffer available to the controller and the controller must be able to deal with short transfers for ATAPI commands which can transfer variable length, this shouldn't break any controllers while making problems like rounding-down and controllers choking up on odd transfer bytes much less likely. The unmodified value is stored in new field qc->raw_nbytes.

A similar issue occurs with the slave returning 0 not 1 if you plug a gigabyte sata ramdisk into a controller that fakes two SATA ports as master/slave on an SFF channel. The patch does the following - Allow the 'failed diagnostics' case on both master and slave - Move the HORKAGE_DIAGNOSTIC check after ->dev_config This second change also allows IT821x to fix up a problem where we report drive diagnostic failures when in fact the drive is fine but the microcontroller firmware doesn't appear to get it right. IT821x clears the flag again to avoid giving the user bogus warnings about their disk. The other IT821x change is a bit ugly, we slightly abuse the cable type hook to fiddle with the identify data for the devices. We could add a new hook for this but as we have only one offender and no more seeming likely it seems better to keep libata-core clean.

This patch implements support for it such that PHY status, errors and hardreset are available for those controllers. This is the only case where two devices on a PATA channel have access to SCRs and creates a unique problem of mapping two SCRs to one link. Note that this is different from PMP case in that they aren't quite separate links - e.g. softreset resets both devices. This problem is worked around by merging the SCR values. To upper layer, it looks like there is a single link with one set of SCRs but with two devices. This works well enough for PHY event, error reporting and hardreset.

The problem occurs if the buffer used to read data spans two pages. The reason is that the PIO sector routines in libata are expecting physically contiguous pages when they do sector operations, so the left overs on the second page go into the next physically adjacent page rather than the next page in the sg mapping. Fix this by enforcing strict 512 byte alignment on all buffers from userspace.

Somewhat reverses a patch from November 7th of last year that removed swap operations because they formerly were being assigned to an u8 array when they should have been assigned to an le32 array. This patch is largely inert for any little endian processor architecture. It resolves a bug in delivering the BlinkLED AIF event to registered applications when the adapter or associated hardware was reset due to ill health.

In experiments in the lab we managed to trigger an Adapter firmware panic (BlinkLED) coincidentally while several pass-through ioctl command from the management software were outstanding on a bug only present on a class of RAID Adapters that require a hardware reset rather than a commanded reset. The net result was an attempt to time out the management software command as if it came from the SCSI layer resulting in an OS panic. Adapters that use commanded reset, management commands are returned failed by the Adapter correctly. The adapter firmware panic that resulted in this condition was also resolved, and there were no adapters in the field with this specific firmware bug so we do not expect any field reports. This is a rare or unlikely corner condition, and no reports have ever been forwarded from the field.

On the other hand, physical targets are only granted a queue depth of one each. The code prior to this patch used to deal with the incremental discovery of targets, but the driver knows how many arrays are present prior to the scan so this knowledge is used to generate a better estimate for the queue depth. Remove the capability of 'physical=0' from preventing access to the class of adapters that have the RAID/SCSI mode of operation since none of the physicals on the SCSI channel are candidates ever for an array. As always, the user can override this default queue depth policy by making the appropriate adjustments utilizing sysfs.

It has already been acked quite long time ago. So I resubmit the patch. http://lkml.org/lkml/2006/11/22/28 Current lpfc driver is already using pci_select_bars() and pci_enable_device_bars() when the PCI bus has been reset. So I think this patch should also be acked.

That variable is only ever filled by a stack based completion. If we find it non empty it means this code has been entered twice and we have a severe problem, so that should just become a BUG_ON(sym_data->io_reset). 2. sym_data->io_reset should be set to NULL before the routine is exited otherwise the PCI recovery code could end up completing what will be a bogus pointer into the stack.

A decision was made to ship the SMC products without a vendor string dropping the defacto space that used to delineate vendor and product to boot. To correct this, we needed to adjust the code in the driver to parse out the vendor and product strings for the adapter. We match of 'AOC' in the AdapterTypeText, if so we set the vendor to SMC and place the entire AdapterTypeText into the product field.

FSACTL_GET_NEXT_ADAPTER_FIB ioctl does not lock dev->fib_list but needs to 2. Ditto for FSACTL_CLOSE_GET_ADAPTER_FIB 3. It is possible to construct an attack via the SRB ioctls where the user obtains assorted elevated privileges. Various approaches are possible, the trivial ones being things like writing to the raw media via scsi commands and the swap image of other executing programs with higher privileges. So the ioctls should be CAP_SYS_RAWIO - at least all the FIB manipulating ones. This is a bandaid fix for #3 but probably the ioctls should grow their own capable checks. The other two bugs need someone competent in that driver to fix them.

FCE support enables the firmware to record FC extended link services and basic link services frames which have been transmitted and received by the ISP. This allows for a limited view of the FC traffic through the ISP without using a FC analyzer. This can be useful in situations where a physical connection to the FC bus is not possible. The driver exports this information in two ways -- first, via a debugfs node exported for all supported ISPs under: /qla2xxx/qla2xxx_/fce where a read of the 'fce' file will provide a snapshot of the firmware's FCE buffer; and finally, the FCE buffer will be extracted during a firmware-dump scenario.

Breaking from the one-line output typical of sysfs entries, newline was added to tailor for grep, or simple gets line by line string match within an application. I added one for a compiler time check for existence of debug print output, one for an optional manifest defined enhanced status reporting in the logs, and one for runtime reporting whether the controller and driver supports arrays larger than 2TB. Adaptec's storage management software uses the last flag to determine whether to make available the creation of arrays larger than 2TB, otherwise a warning is posted.

The cards being added are supported in a limited sense already through family matching, but we needed to add some functionality to the driver to expose selectively the physical drives. These Physical drives are specifically marked to not be part of any array and thus are declared JBODs (Just a Bunch Of Drives) for generic SCSI access. We report that this is the second patch in a set of two, but merely depends on the stand-alone functionality of the first patch which adds in that case the ability to report a driver feature flag via sysfs. We leverage that functionality by reporting that this driver now supports this new JBOD feature for the controller so that the array management applications may react accordingly and guide the user as they manage the controller.

The reason for doing this is that some architectures need cacheline aligned buffer for DMA: http://lkml.org/lkml/2007/11/19/2 The problems are that scsi_eh_prep_cmnd puts scsi_cmnd::sense_buffer to sglist and some LLDs directly DMA to scsi_cmnd::sense_buffer. It's necessary to DMA to scsi_cmnd::sense_buffer safely.

When a user of hugepages exits using this code the system leaks some of the hugepages. ------------------------------------------------------- Part of /proc/meminfo just before database startup: HugePages_Total: 5500 HugePages_Free: 5500 HugePages_Rsvd: 0 Hugepagesize: 2048 kB Just before shutdown: HugePages_Total: 5500 HugePages_Free: 4475 HugePages_Rsvd: 0 Hugepagesize: 2048 kB After shutdown: HugePages_Total: 5500 HugePages_Free: 4988 HugePages_Rsvd: 0 Hugepagesize: 2048 kB ---------------------------------------------------------- The problem occurs durring a fork, in copy_hugetlb_page_range(). It locates the dst_pte using huge_pte_alloc(). Since huge_pte_alloc() calls huge_pmd_share() it will share the pmd page if can, yet the main loop in copy_hugetlb_page_range() does a get_page() on every hugepage. This is a violation of the shared hugepmd pagetable protocol and creates additional referenced to the hugepages causing a leak when the unmap of the VMA occurs. We can skip the entire replication of the ptes when the hugepage pagetables are shared. The attached patch skips copying the ptes and the get_page() calls if the hugetlbpage pagetable is shared.

This will allow filesystems to directly own and control all of their mount options if they so choose. This interface deals only with option identifiers and strings so it should generic enough for any LSM which may come in the future. Filesystems which pass text mount data around in the kernel (almost all of them) need not currently make use of this interface when dealing with SELinux since it will still parse those strings as it always has. I assume future LSM's would do the same. NFS is the primary FS which does not use text mount data and thus must make use of this interface. An LSM would need to implement these functions only if they had mount time options, such as selinux has context= or fscontext=. If the LSM has no mount time options they could simply not implement and let the dummy ops take care of things. An LSM other than SELinux would need to define new option numbers in security.h and any FS which decides to own there own security options would need to be patched to use this new interface for every possible LSM.

charset=us-ascii; format=flowed +---- 邮件头 ---- +问题在于 “format=flowed” 会让接收端的某些邮件软件将邮件中的制表符替换 +成空格以及做一些类似的替换。这样，你发送的时候看起来没问题的补丁就被破 +坏了。 + +要修正这个问题，只需要将你的 mozilla 的 defaults/pref/mailnews.js 文件 +里的 +pref("mailnews.send_plaintext_flowed", false); // RFC 2646======= +修改成 +pref("mailnews.display.disable_format_flowed_support", true); +就可以了。 + +7) e-mail 的大小 + +给 Linus 发送补丁的时候，永远按照第6小节说的做。 + +大的改动对邮件列表不合适，对某些维护者也不合适。如果你的补丁，在不压缩 +的情况下，超过了40kB，那么你最好将补丁放在一个能通过 internet 访问的服 +务器上，然后用指向你的补丁的 URL 替代。 + +8) 指出你的内核版本 + +在标题和在补丁的描述中，指出补丁对应的内核的版本，是很重要的。 + +如果补丁不能干净的在最新版本的内核上打上，Linus 是不会接受它的。 + +9) 不要气馁，继续提交。 + +当你提交了改动以后，耐心地等待。如果 Linus 喜欢你的改动并且同意它，那么 +它将在下一个内核发布版本中出现。 + +然而，如果你的改动没有出现在下一个版本的内核中，可能有若干原因。减少那 +些原因，修正错误，重新提交更新后的改动，是你自己的工作。 + +Linus不给出任何评论就“丢弃”你的补丁是常见的事情。在系统中这样的事情很 +平常。如果他没有接受你的补丁，也许是由于以下原本： +* 你的补丁不能在最新版本的内核上干净的打上。 +* 你的补丁在 linux-kernel 邮件列表中没有得到充分的讨论。 +* 风格问题（参照第2小节） +* 邮件格式问题（重读本节） +* 你的改动有技术问题。 +* 他收到了成吨的 e-mail，而你的在混乱中丢失了。 +* 你让人为难。 + +有疑问的时候，在 linux-kernel 邮件列表上请求评论。 + +10) 在标题上加上 PATCH 的字样 + +Linus 和 linux-kernel 邮件列表的 e-mail 流量都很高，一个通常的约定是标 +题行以 [PATCH] 开头。这样可以让 Linus 和其他内核开发人员可以从 e-mail +的讨论中很轻易的将补丁分辨出来。 + +11）为你的工作签名 + +为了加强对谁做了何事的追踪，尤其是对那些透过好几层的维护者的补丁，我们 +建议在发送出去的补丁上加一个 “sign-off” 的过程。 + +"sign-off" 是在补丁的注释的最后的简单的一行文字，认证你编写了它或者其他 +人有权力将它作为开放源代码的补丁传递。规则很简单：如果你能认证如下信息 +： + 开发者来源证书 1.1 + 对于本项目的贡献，我认证如下信息： + （a）这些贡献是完全或者部分的由我创建，我有权利以文件中指出 + 的开放源代码许可证提交它；或者 + （b）这些贡献基于以前的工作，据我所知，这些以前的工作受恰当的开放 + 源代码许可证保护，而且，根据许可证，我有权提交修改后的贡献， + 无论是完全还是部分由我创造，这些贡献都使用同一个开放源代码许可证 + （除非我被允许用其它的许可证），正如文件中指出的；或者 + （c）这些贡献由认证（a），（b）或者（c）的人直接提供给我，而 + 且我没有修改它。 + （d）我理解并同意这个项目和贡献是公开的，贡献的记录（包括我 + 一起提交的个人记录，包括 sign-off ）被永久维护并且可以和这个项目 + 或者开放源代码的许可证同步地再发行。 + 那么加入这样一行： + Signed-off-by: Random J Developer + +使用你的真名（抱歉，不能使用假名或者匿名。） + +有人在最后加上标签。现在这些东西会被忽略，但是你可以这样做，来标记公司 +内部的过程，或者只是指出关于 sign-off 的一些特殊细节。 + +12）标准补丁格式 + +标准的补丁，标题行是： + Subject: [PATCH 001/123] 子系统:一句话概述 + +标准补丁的信体存在如下部分： + + - 一个 "from" 行指出补丁作者。 + + - 一个空行 + + - 说明的主体，这些说明文字会被拷贝到描述该补丁的永久改动记录里。 + + - 一个由"---"构成的标记行 + + - 不合适放到改动记录里的额外的注解。 + + - 补丁本身（diff 输出） + +标题行的格式，使得对标题行按字母序排序非常的容易 - 很多 e-mail 客户端都 +可以支持 - 因为序列号是用零填充的，所以按数字排序和按字母排序是一样的。 + +e-mail 标题中的“子系统”标识哪个内核子系统将被打补丁。 + +e-mail 标题中的“一句话概述”扼要的描述 e-mail 中的补丁。“一句话概述” +不应该是一个文件名。对于一个补丁系列（“补丁系列”指一系列的多个相关补 +丁），不要对每个补丁都使用同样的“一句话概述”。 + +记住 e-mail 的“一句话概述”会成为该补丁的全局唯一标识。它会蔓延到 git +的改动记录里。然后“一句话概述”会被用在开发者的讨论里，用来指代这个补 +丁。用户将希望通过 google 来搜索"一句话概述"来找到那些讨论这个补丁的文 +章。 + +一些标题的例子： + + Subject: [patch 2/5] ext2: improve scalability of bitmap searching + Subject: [PATCHv2 001/207] x86: fix eflags tracking + +"from" 行是信体里的最上面一行，具有如下格式： + From: Original Author + +"from" 行指明在永久改动日志里，谁会被确认为作者。如果没有 "from" 行，那 +么邮件头里的 "From: " 行会被用来决定改动日志中的作者。 + +说明的主题将会被提交到永久的源代码改动日志里，因此对那些早已经不记得和 +这个补丁相关的讨论细节的有能力的读者来说，是有意义的。 + +"---" 标记行对于补丁处理工具要找到哪里是改动日志信息的结束，是不可缺少 +的。 + +对于 "---" 标记之后的额外注解，一个好的用途就是用来写 diffstat，用来显 +示修改了什么文件和每个文件都增加和删除了多少行。diffstat 对于比较大的补 +丁特别有用。其余那些只是和时刻或者开发者相关的注解，不合适放到永久的改 +动日志里的，也应该放这里。 +使用 diffstat的选项 "-p 1 -w 70" 这样文件名就会从内核源代码树的目录开始 +，不会占用太宽的空间（很容易适合80列的宽度，也许会有一些缩进。） + +在后面的参考资料中能看到适当的补丁格式的更多细节。 + +------------------------------- +第二节 提示，建议和诀窍 +------------------------------- + +本节包含很多和提交到内核的代码有关的通常的"规则"。事情永远有例外...但是 +你必须真的有好的理由这样做。你可以把本节叫做Linus的计算机科学入门课。 + +1) 读 Document/CodingStyle + +Nuff 说过，如果你的代码和这个偏离太多，那么它有可能会被拒绝，没有更多的 +审查，没有更多的评价。 + +2) #ifdef 是丑陋的 +混杂了 ifdef 的代码难以阅读和维护。别这样做。作为替代，将你的 ifdef 放 +在头文件里，有条件地定义 "static inline" 函数，或者宏，在代码里用这些东 +西。让编译器把那些"空操作"优化掉。 + +一个简单的例子，不好的代码： + + dev = alloc_etherdev (sizeof(struct funky_private)); + if (!dev) + return -ENODEV; + #ifdef CONFIG_NET_FUNKINESS + init_funky_net(dev); + #endif + +清理后的例子: + +(头文件里) + #ifndef CONFIG_NET_FUNKINESS + static inline void init_funky_net (struct net_device *d) {} + #endif + +(代码文件里) + dev = alloc_etherdev (sizeof(struct funky_private)); + if (!dev) + return -ENODEV; + init_funky_net(dev); + +3) 'static inline' 比宏好 + +Static inline 函数相比宏来说，是好得多的选择。Static inline 函数提供了 +类型安全，没有长度限制，没有格式限制，在 gcc 下开销和宏一样小。 + +宏只在 static inline 函数不是最优的时候[在 fast paths 里有很少的独立的 +案例]，或者不可能用 static inline 函数的时候[例如字符串分配]。 +应该用 'static inline' 而不是 'static __inline__', 'extern inline' 和 +'extern __inline__' 。 + +4) 不要过度设计 + +不要试图预计模糊的未来事情，这些事情也许有用也许没有用："让事情尽可能的 +简单，而不是更简单"。 + +---------------- +第三节 参考文献 +---------------- + +Andrew Morton, "The perfect patch" (tpp). + + +Jeff Garzik, "Linux kernel patch submission format". + + +Greg Kroah-Hartman, "How to piss off a kernel subsystem maintainer". + + + + + +NO!!!!

+ break; + case 'M': + case 'm': + mem <<= 20; + break; + case 'K': + case 'k': + mem <<= 10; + /* fall through */ + default: + break; + } + + +不要把多个语句放在一行里，除非你有什么东西要隐藏： + + if (condition) do_this; + do_something_everytime; + +也不要在一行里放多个赋值语句。内核代码风格超级简单。就是避免可能导致别人误读的表 +达式。 + +除了注释、文档和Kconfig之外，不要使用空格来缩进，前面的例子是例外，是有意为之。 + +选用一个好的编辑器，不要在行尾留空格。 + + + 第二章：把长的行和字符串打散 + +代码风格的意义就在于使用平常使用的工具来维持代码的可读性和可维护性。 + +每一行的长度的限制是80列，我们强烈建议您遵守这个惯例。 + +长于80列的语句要打散成有意义的片段。每个片段要明显短于原来的语句，而且放置的位置 +也明显的靠右。同样的规则也适用于有很长参数列表的函数头。长字符串也要打散成较短的 +字符串。唯一的例外是超过80列可以大幅度提高可读性并且不会隐藏信息的情况。 + +void fun(int a, int b, int c) +{ + if (condition) + printk(KERN_WARNING "Warning this is a long printk with " + "3 parameters a: %u b: %u " + "c: %u \n", a, b, c); + else + next_statement; +} + + 第三章：大括号和空格的放置 + +C语言风格中另外一个常见问题是大括号的放置。和缩进大小不同，选择或弃用某种放置策 +略并没有多少技术上的原因，不过首选的方式，就像Kernighan和Ritchie展示给我们的，是 +把起始大括号放在行尾，而把结束大括号放在行首，所以： + + if (x is true) { + we do y + } + +这适用于所有的非函数语句块（if、switch、for、while、do）。比如： + + switch (action) { + case KOBJ_ADD: + return "add"; + case KOBJ_REMOVE: + return "remove"; + case KOBJ_CHANGE: + return "change"; + default: + return NULL; + } + +不过，有一个例外，那就是函数：函数的起始大括号放置于下一行的开头，所以： + + int function(int x) + { + body of function + } + +全世界的异端可能会抱怨这个不一致性是……呃……不一致的，不过所有思维健全的人都知道（ +a）K&R是_正确的_，并且（b）K&R是正确的。此外，不管怎样函数都是特殊的（在C语言中 +，函数是不能嵌套的）。 + +注意结束大括号独自占据一行，除非它后面跟着同一个语句的剩余部分，也就是do语句中的 +“while”或者if语句中的“else”，像这样： + + do { + body of do-loop + } while (condition); + +和 + + if (x == y) { + .. + } else if (x > y) { + ... + } else { + .... + } + +理由：K&R。 + +也请注意这种大括号的放置方式也能使空（或者差不多空的）行的数量最小化，同时不失可 +读性。因此，由于你的屏幕上的新行是不可再生资源（想想25行的终端屏幕），你将会有更 +多的空行来放置注释。 + +当只有一个单独的语句的时候，不用加不必要的大括号。 + +if (condition) + action(); + +这点不适用于本身为某个条件语句的一个分支的单独语句。这时需要在两个分支里都使用大 +括号。 + +if (condition) { + do_this(); + do_that(); +} else { + otherwise(); +} + + 3.1：空格 + +Linux内核的空格使用方式（主要）取决于它是用于函数还是关键字。（大多数）关键字后 +要加一个空格。值得注意的例外是sizeof、typeof、alignof和__attribute__，这些关键字 +某些程度上看起来更像函数（它们在Linux里也常常伴随小括号而使用，尽管在C语言里这样 +的小括号不是必需的，就像“struct fileinfo info”声明过后的“sizeof info”）。 + +所以在这些关键字之后放一个空格： + if, switch, case, for, do, while +但是不要在sizeof、typeof、alignof或者__attribute__这些关键字之后放空格。例如， + s = sizeof(struct file); + +不要在小括号里的表达式两侧加空格。这是一个反例： + + s = sizeof( struct file ); + +当声明指针类型或者返回指针类型的函数时，“*”的首选使用方式是使之靠近变量名或者函 +数名，而不是靠近类型名。例子： + + char *linux_banner; + unsigned long long memparse(char *ptr, char **retptr); + char *match_strdup(substring_t *s); + +在大多数二元和三元操作符两侧使用一个空格，例如下面所有这些操作符： + + = + - < > * / % | & ^ <= >= == != ? : + +但是一元操作符后不要加空格： + & * + - ~ ! sizeof typeof alignof __attribute__ defined + +后缀自加和自减一元操作符前不加空格： + ++ -- + +前缀自加和自减一元操作符后不加空格： + ++ -- + +“.”和“->”结构体成员操作符前后不加空格。 + +不要在行尾留空白。有些可以自动缩进的编辑器会在新行的行首加入适量的空白，然后你 +就可以直接在那一行输入代码。不过假如你最后没有在那一行输入代码，有些编辑器就不 +会移除已经加入的空白，就像你故意留下一个只有空白的行。包含行尾空白的行就这样产 +生了。 + +当git发现补丁包含了行尾空白的时候会警告你，并且可以应你的要求去掉行尾空白；不过 +如果你是正在打一系列补丁，这样做会导致后面的补丁失败，因为你改变了补丁的上下文。 + + + 第四章：命名 + +C是一个简朴的语言，你的命名也应该这样。和Modula-2和Pascal程序员不同，C程序员不使 +用类似ThisVariableIsATemporaryCounter这样华丽的名字。C程序员会称那个变量为“tmp” +，这样写起来会更容易，而且至少不会令其难于理解。 + +不过，虽然混用大小写的名字是不提倡使用的，但是全局变量还是需要一个具描述性的名字 +。称一个全局函数为“foo”是一个难以饶恕的错误。 + +全局变量（只有当你真正需要它们的时候再用它）需要有一个具描述性的名字，就像全局函 +数。如果你有一个可以计算活动用户数量的函数，你应该叫它“count_active_users()”或者 +类似的名字，你不应该叫它“cntuser()”。 + +在函数名中包含函数类型（所谓的匈牙利命名法）是脑子出了问题——编译器知道那些类型而 +且能够检查那些类型，这样做只能把程序员弄糊涂了。难怪微软总是制造出有问题的程序。 + +本地变量名应该简短，而且能够表达相关的含义。如果你有一些随机的整数型的循环计数器 +，它应该被称为“i”。叫它“loop_counter”并无益处，如果它没有被误解的可能的话。类似 +的，“tmp”可以用来称呼任意类型的临时变量。 + +如果你怕混淆了你的本地变量名，你就遇到另一个问题了，叫做函数增长荷尔蒙失衡综合症 +。请看第六章（函数）。 + + + 第五章：Typedef + +不要使用类似“vps_t”之类的东西。 + +对结构体和指针使用typedef是一个错误。当你在代码里看到： + + vps_t a; + +这代表什么意思呢？ + +相反，如果是这样 + + struct virtual_container *a; + +你就知道“a”是什么了。 + +很多人认为typedef“能提高可读性”。实际不是这样的。它们只在下列情况下有用： + + (a) 完全不透明的对象（这种情况下要主动使用typedef来隐藏这个对象实际上是什么）。 + + 例如：“pte_t”等不透明对象，你只能用合适的访问函数来访问它们。 + + 注意！不透明性和“访问函数”本身是不好的。我们使用pte_t等类型的原因在于真的是 + 完全没有任何共用的可访问信息。 + + (b) 清楚的整数类型，如此，这层抽象就可以帮助消除到底是“int”还是“long”的混淆。 + + u8/u16/u32是完全没有问题的typedef，不过它们更符合类别(d)而不是这里。 + + 再次注意！要这样做，必须事出有因。如果某个变量是“unsigned long“，那么没有必要 + + typedef unsigned long myflags_t; + + 不过如果有一个明确的原因，比如它在某种情况下可能会是一个“unsigned int”而在 + 其他情况下可能为“unsigned long”，那么就不要犹豫，请务必使用typedef。 + + (c) 当你使用sparse按字面的创建一个新类型来做类型检查的时候。 + + (d) 和标准C99类型相同的类型，在某些例外的情况下。 + + 虽然让眼睛和脑筋来适应新的标准类型比如“uint32_t”不需要花很多时间，可是有些 + 人仍然拒绝使用它们。 + + 因此，Linux特有的等同于标准类型的“u8/u16/u32/u64”类型和它们的有符号类型是被 + 允许的——尽管在你自己的新代码中，它们不是强制要求要使用的。 + + 当编辑已经使用了某个类型集的已有代码时，你应该遵循那些代码中已经做出的选择。 + + (e) 可以在用户空间安全使用的类型。 + + 在某些用户空间可见的结构体里，我们不能要求C99类型而且不能用上面提到的“u32” + 类型。因此，我们在与用户空间共享的所有结构体中使用__u32和类似的类型。 + +可能还有其他的情况，不过基本的规则是永远不要使用typedef，除非你可以明确的应用上 +述某个规则中的一个。 + +总的来说，如果一个指针或者一个结构体里的元素可以合理的被直接访问到，那么它们就不 +应该是一个typedef。 + + + 第六章：函数 + +函数应该简短而漂亮，并且只完成一件事情。函数应该可以一屏或者两屏显示完（我们都知 +道ISO/ANSI屏幕大小是80x24），只做一件事情，而且把它做好。 + +一个函数的最大长度是和该函数的复杂度和缩进级数成反比的。所以，如果你有一个理论上 +很简单的只有一个很长（但是简单）的case语句的函数，而且你需要在每个case里做很多很 +小的事情，这样的函数尽管很长，但也是可以的。 + +不过，如果你有一个复杂的函数，而且你怀疑一个天分不是很高的高中一年级学生可能甚至 +搞不清楚这个函数的目的，你应该严格的遵守前面提到的长度限制。使用辅助函数，并为之 +取个具描述性的名字（如果你觉得它们的性能很重要的话，可以让编译器内联它们，这样的 +效果往往会比你写一个复杂函数的效果要好。） + +函数的另外一个衡量标准是本地变量的数量。此数量不应超过5－10个，否则你的函数就有 +问题了。重新考虑一下你的函数，把它分拆成更小的函数。人的大脑一般可以轻松的同时跟 +踪7个不同的事物，如果再增多的话，就会糊涂了。即便你聪颖过人，你也可能会记不清你2 +个星期前做过的事情。 + +在源文件里，使用空行隔开不同的函数。如果该函数需要被导出，它的EXPORT*宏应该紧贴 +在它的结束大括号之下。比如： + +int system_is_up(void) +{ + return system_state == SYSTEM_RUNNING; +} +EXPORT_SYMBOL(system_is_up); + +在函数原型中，包含函数名和它们的数据类型。虽然C语言里没有这样的要求，在Linux里这 +是提倡的做法，因为这样可以很简单的给读者提供更多的有价值的信息。 + + + 第七章：集中的函数退出途径 + +虽然被某些人声称已经过时，但是goto语句的等价物还是经常被编译器所使用，具体形式是 +无条件跳转指令。 + +当一个函数从多个位置退出并且需要做一些通用的清理工作的时候，goto的好处就显现出来 +了。 + +理由是： + +- 无条件语句容易理解和跟踪 +- 嵌套程度减小 +- 可以避免由于修改时忘记更新某个单独的退出点而导致的错误 +- 减轻了编译器的工作，无需删除冗余代码;) + +int fun(int a) +{ + int result = 0;

+} + + 第八章：注释 + +注释是好的，不过有过度注释的危险。永远不要在注释里解释你的代码是如何运作的：更好 +的做法是让别人一看你的代码就可以明白，解释写的很差的代码是浪费时间。 + +一般的，你想要你的注释告诉别人你的代码做了什么，而不是怎么做的。也请你不要把注释 +放在一个函数体内部：如果函数复杂到你需要独立的注释其中的一部分，你很可能需要回到 +第六章看一看。你可以做一些小注释来注明或警告某些很聪明（或者槽糕）的做法，但不要 +加太多。你应该做的，是把注释放在函数的头部，告诉人们它做了什么，也可以加上它做这 +些事情的原因。 + +当注释内核API函数时，请使用kernel-doc格式。请看 +Documentation/kernel-doc-nano-HOWTO.txt和scripts/kernel-doc以获得详细信息。 + +Linux的注释风格是C89“/* ... */”风格。不要使用C99风格“// ...”注释。 + +长（多行）的首选注释风格是： + + /* + * This is the preferred style for multi-line + * comments in the Linux kernel source code. + * Please use it consistently. + * + * Description: A column of asterisks on the left side, + * with beginning and ending almost-blank lines. + */ + +注释数据也是很重要的，不管是基本类型还是衍生类型。为了方便实现这一点，每一行应只 +声明一个数据（不要使用逗号来一次声明多个数据）。这样你就有空间来为每个数据写一段 +小注释来解释它们的用途了。 + + + 第九章：你已经把事情弄糟了 + +这没什么，我们都是这样。可能你的使用了很长时间Unix的朋友已经告诉你“GNU emacs”能 +自动帮你格式化C源代码，而且你也注意到了，确实是这样，不过它所使用的默认值和我们 +想要的相去甚远（实际上，甚至比随机打的还要差——无数个猴子在GNU emacs里打字永远不 +会创造出一个好程序）（译注：请参考Infinite Monkey Theorem） + +所以你要么放弃GNU emacs，要么改变它让它使用更合理的设定。要采用后一个方案，你可 +以把下面这段粘贴到你的.emacs文件里。 + +(defun linux-c-mode () + "C mode with adjusted defaults for use with the Linux kernel." + (interactive) + (c-mode) + (c-set-style "K&R") + (setq tab-width 8) + (setq indent-tabs-mode t) + (setq c-basic-offset 8)) + +这样就定义了M-x linux-c-mode命令。当你hack一个模块的时候，如果你把字符串 +-*- linux-c -*-放在头两行的某个位置，这个模式将会被自动调用。如果你希望在你修改 +/usr/src/linux里的文件时魔术般自动打开linux-c-mode的话，你也可能需要添加 + +(setq auto-mode-alist (cons '("/usr/src/linux.*/.*\\.[ch]$" . linux-c-mode) + auto-mode-alist)) + +到你的.emacs文件里。 + +不过就算你尝试让emacs正确的格式化代码失败了，也并不意味着你失去了一切：还可以用“ +indent”。 + +不过，GNU indent也有和GNU emacs一样有问题的设定，所以你需要给它一些命令选项。不 +过，这还不算太糟糕，因为就算是GNU indent的作者也认同K&R的权威性（GNU的人并不是坏 +人，他们只是在这个问题上被严重的误导了），所以你只要给indent指定选项“-kr -i8” +（代表“K&R，8个字符缩进”），或者使用“scripts/Lindent”，这样就可以以最时髦的方式 +缩进源代码。 + +“indent”有很多选项，特别是重新格式化注释的时候，你可能需要看一下它的手册页。不过 +记住：“indent”不能修正坏的编程习惯。 + + + 第十章：Kconfig配置文件 + +对于遍布源码树的所有Kconfig*配置文件来说，它们缩进方式与C代码相比有所不同。紧挨 +在“config”定义下面的行缩进一个制表符，帮助信息则再多缩进2个空格。比如： + +config AUDIT + bool "Auditing support" + depends on NET + help + Enable auditing infrastructure that can be used with another + kernel subsystem, such as SELinux (which requires this for + logging of avc messages output). Does not do system-call + auditing without CONFIG_AUDITSYSCALL. + +仍然被认为不够稳定的功能应该被定义为依赖于“EXPERIMENTAL”： + +config SLUB + depends on EXPERIMENTAL && !ARCH_USES_SLAB_PAGE_STRUCT + bool "SLUB (Unqueued Allocator)" + ... + +而那些危险的功能（比如某些文件系统的写支持）应该在它们的提示字符串里显著的声明这 +一点： + +config ADFS_FS_RW + bool "ADFS write support (DANGEROUS)" + depends on ADFS_FS + ... + +要查看配置文件的完整文档，请看Documentation/kbuild/kconfig-language.txt。 + + + 第十一章：数据结构 + +如果一个数据结构，在创建和销毁它的单线执行环境之外可见，那么它必须要有一个引用计 +数器。内核里没有垃圾收集（并且内核之外的垃圾收集慢且效率低下），这意味着你绝对需 +要记录你对这种数据结构的使用情况。 + +引用计数意味着你能够避免上锁，并且允许多个用户并行访问这个数据结构——而不需要担心 +这个数据结构仅仅因为暂时不被使用就消失了，那些用户可能不过是沉睡了一阵或者做了一 +些其他事情而已。 + +注意上锁不能取代引用计数。上锁是为了保持数据结构的一致性，而引用计数是一个内存管 +理技巧。通常二者都需要，不要把两个搞混了。 + +很多数据结构实际上有2级引用计数，它们通常有不同“类”的用户。子类计数器统计子类用 +户的数量，每当子类计数器减至零时，全局计数器减一。 + +这种“多级引用计数”的例子可以在内存管理（“struct mm_struct”：mm_users和mm_count） +和文件系统（“struct super_block”：s_count和s_active）中找到。 + +记住：如果另一个执行线索可以找到你的数据结构，但是这个数据结构没有引用计数器，这 +里几乎肯定是一个bug。 + + + 第十二章：宏，枚举和RTL + +用于定义常量的宏的名字及枚举里的标签需要大写。 + +#define CONSTANT 0x12345 + +在定义几个相关的常量时，最好用枚举。 + +宏的名字请用大写字母，不过形如函数的宏的名字可以用小写字母。 + +一般的，如果能写成内联函数就不要写成像函数的宏。 + +含有多个语句的宏应该被包含在一个do-while代码块里： + +#define macrofun(a, b, c) \ + do { \ + if (a == 5) \ + do_this(b, c); \ + } while (0) + +使用宏的时候应避免的事情： + +1) 影响控制流程的宏： + +#define FOO(x) \ + do { \ + if (blah(x) < 0) \ + return -EBUGGERED; \ + } while(0) + +非常不好。它看起来像一个函数，不过却能导致“调用”它的函数退出；不要打乱读者大脑里 +的语法分析器。 + +2) 依赖于一个固定名字的本地变量的宏： + +#define FOO(val) bar(index, val) + +可能看起来像是个不错的东西，不过它非常容易把读代码的人搞糊涂，而且容易导致看起来 +不相关的改动带来错误。 + +3) 作为左值的带参数的宏： FOO(x) = y；如果有人把FOO变成一个内联函数的话，这种用 +法就会出错了。 + +4) 忘记了优先级：使用表达式定义常量的宏必须将表达式置于一对小括号之内。带参数的 +宏也要注意此类问题。 + +#define CONSTANT 0x4000 +#define CONSTEXP (CONSTANT | 3) + +cpp手册对宏的讲解很详细。Gcc internals手册也详细讲解了RTL（译注：register +transfer language），内核里的汇编语言经常用到它。 + + + 第十三章：打印内核消息 + +内核开发者应该是受过良好教育的。请一定注意内核信息的拼写，以给人以好的印象。不要 +用不规范的单词比如“dont”，而要用“do not”或者“don't”。保证这些信息简单、明了、无 +歧义。 + +内核信息不必以句号（译注：英文句号，即点）结束。 + +在小括号里打印数字(%d)没有任何价值，应该避免这样做。 + +里有一些驱动模型诊断宏，你应该使用它们，以确保信息对应于正确的 +设备和驱动，并且被标记了正确的消息级别。这些宏有：dev_err(), dev_warn(), +dev_info()等等。对于那些不和某个特定设备相关连的信息，定义了 +pr_debug()和pr_info()。 + +写出好的调试信息可以是一个很大的挑战；当你写出来之后，这些信息在远程除错的时候 +就会成为极大的帮助。当DEBUG符号没有被定义的时候，这些信息不应该被编译进内核里 +（也就是说，默认地，它们不应该被包含在内）。如果你使用dev_dbg()或者pr_debug()， +就能自动达到这个效果。很多子系统拥有Kconfig选项来启用-DDEBUG。还有一个相关的惯例 +是使用VERBOSE_DEBUG来添加dev_vdbg()消息到那些已经由DEBUG启用的消息之上。 + + + 第十四章：分配内存 + +内核提供了下面的一般用途的内存分配函数：kmalloc()，kzalloc()，kcalloc()和 +vmalloc()。请参考API文档以获取有关它们的详细信息。 + +传递结构体大小的首选形式是这样的： + + p = kmalloc(sizeof(*p), ...); + +另外一种传递方式中，sizeof的操作数是结构体的名字，这样会降低可读性，并且可能会引 +入bug。有可能指针变量类型被改变时，而对应的传递给内存分配函数的sizeof的结果不变。 + +强制转换一个void指针返回值是多余的。C语言本身保证了从void指针到其他任何指针类型 +的转换是没有问题的。 + + + 第十五章：内联弊病 + +有一个常见的误解是内联函数是gcc提供的可以让代码运行更快的一个选项。虽然使用内联 +函数有时候是恰当的（比如作为一种替代宏的方式，请看第十二章），不过很多情况下不是 +这样。inline关键字的过度使用会使内核变大，从而使整个系统运行速度变慢。因为大内核 +会占用更多的指令高速缓存（译注：一级缓存通常是指令缓存和数据缓存分开的）而且会导 +致pagecache的可用内存减少。想象一下，一次pagecache未命中就会导致一次磁盘寻址，将 +耗时5毫秒。5毫秒的时间内CPU能执行很多很多指令。 + +一个基本的原则是如果一个函数有3行以上，就不要把它变成内联函数。这个原则的一个例 +外是，如果你知道某个参数是一个编译时常量，而且因为这个常量你确定编译器在编译时能 +优化掉你的函数的大部分代码，那仍然可以给它加上inline关键字。kmalloc()内联函数就 +是一个很好的例子。 + +人们经常主张给static的而且只用了一次的函数加上inline，如此不会有任何损失，因为没 +有什么好权衡的。虽然从技术上说这是正确的，但是实际上这种情况下即使不加inline gcc +也可以自动使其内联。而且其他用户可能会要求移除inline，由此而来的争论会抵消inline +自身的潜在价值，得不偿失。 + + + 第十六章：函数返回值及命名 + +函数可以返回很多种不同类型的值，最常见的一种是表明函数执行成功或者失败的值。这样 +的一个值可以表示为一个错误代码整数（-Exxx＝失败，0＝成功）或者一个“成功”布尔值（ +0＝失败，非0＝成功）。 + +混合使用这两种表达方式是难于发现的bug的来源。如果C语言本身严格区分整形和布尔型变 +量，那么编译器就能够帮我们发现这些错误……不过C语言不区分。为了避免产生这种bug，请 +遵循下面的惯例： + + 如果函数的名字是一个动作或者强制性的命令，那么这个函数应该返回错误代码整 + 数。如果是一个判断，那么函数应该返回一个“成功”布尔值。 + +比如，“add work”是一个命令，所以add_work()函数在成功时返回0，在失败时返回-EBUSY。 +类似的，因为“PCI device present”是一个判断，所以pci_dev_present()函数在成功找到 +一个匹配的设备时应该返回1，如果找不到时应该返回0。 + +所有导出（译注：EXPORT）的函数都必须遵守这个惯例，所有的公共函数也都应该如此。私 +有（static）函数不需要如此，但是我们也推荐这样做。 + +返回值是实际计算结果而不是计算是否成功的标志的函数不受此惯例的限制。一般的，他们 +通过返回一些正常值范围之外的结果来表示出错。典型的例子是返回指针的函数，他们使用 +NULL或者ERR_PTR机制来报告错误。 + + + 第十七章：不要重新发明内核宏 + +头文件include/linux/kernel.h包含了一些宏，你应该使用它们，而不要自己写一些它们的 +变种。比如，如果你需要计算一个数组的长度，使用这个宏 + + #define ARRAY_SIZE(x) (sizeof(x) / sizeof((x)[0])) + +类似的，如果你要计算某结构体成员的大小，使用 + + #define FIELD_SIZEOF(t, f) (sizeof(((t*)0)->f)) + +还有可以做严格的类型检查的min()和max()宏，如果你需要可以使用它们。你可以自己看看 +那个头文件里还定义了什么你可以拿来用的东西，如果有定义的话，你就不应在你的代码里 +自己重新定义。 + + + 第十八章：编辑器模式行和其他需要罗嗦的事情 + +有一些编辑器可以解释嵌入在源文件里的由一些特殊标记标明的配置信息。比如，emacs +能够解释被标记成这样的行： + +-*- mode: c -*- + +或者这样的： + +/* +Local Variables: +compile-command: "gcc -DMAGIC_DEBUG_FLAG foo.c" +End: +*/ + +Vim能够解释这样的标记： + +/* vim:set sw=8 noet */ + +不要在源代码中包含任何这样的内容。每个人都有他自己的编辑器配置，你的源文件不应 +该覆盖别人的配置。这包括有关缩进和模式配置的标记。人们可以使用他们自己定制的模 +式，或者使用其他可以产生正确的缩进的巧妙方法。 + + + + 附录 I：参考 + +The C Programming Language, 第二版, 作者Brian W.

Wysocki" Date: Sat, 12 Jan 2008 20:40:46 +0100 Subject: PM: Acquire device locks on suspend This patch reorganizes the way suspend and resume notifications are sent to drivers. The major changes are that now the PM core acquires every device semaphore before calling the methods, and calls to device_add() during suspends will fail, while calls to device_del() during suspends will block. It also provides a way to safely remove a suspended device with the help of the PM core, by using the device_pm_schedule_removal() callback introduced specifically for this purpose, and updates two drivers (msr and cpuid) that need to use it.

We should set this explicitly every time for each kset. This change is needed so that we can make ksets dynamic, and cleans up one of the odd, undocumented assumption that the kset/kobject/ktype model has.

Kobjects are instances of objects (like struct user_info), ksets are collections of objects of a similar type (like the uids directory containing the user_info directories). So, use kobjects for the user_info directories, and a kset for the "uids" directory. On object cleanup, the final kobject_put() was missing.

So much so that it's almost impossible to fix with a simple patch, so just comment out the offending registration with the kobject core, and mark the driver as broken. The problem is that the code is trying to register a "raw" struct device, which is not allowed. struct device is only for use within the driver model. This is being done to try to use the firmware layer which wants a struct device. To properly fix this, use something easy, like a platform device, which is a struct device and can be used for this kind of thing.

This moves the kobject in the structure out of it, and a bunch of other private only to the driver core fields are now moved to a private structure. This lets us dynamically create the backing kobject properly and gives us the chance to be able to document to users exactly how to use the struct bus_type as there are no fields they can improperly access. Thanks to Kay for the build fixes on this patch.

The format for new kobject debug messages should be: driver/bus/class: 'OBJECT_NAME': FUNCTION_NAME: message.\n Note, the class code is not changed in this patch due to pending patches in my queue that this would conflict with. A later patch will clean them up.

If a device is unregistered at the same time as its driver is unloaded, the driver's code pages may be unmapped while the remove method is still running. The calls to get_driver() and put_driver() were intended to prevent this, but they don't work if the driver's module count has already dropped to 0. Instead, the patch keeps the device on the driver's list until after the remove method has returned. This forces the necessary synchronization to occur.

The intent back then was to avoid certain kinds of invalid memory accesses by leaving kernel objects allocated as long as any of their children were still allocated. The original and correct approach was to wait only as long as any children were still _registered_; that's what this patch reinstates. This fixes a problem in the SCSI core made visible by the class_device to regular device conversion: A reference loop (scsi_device holds reference to request_queue, which is the child of a gendisk, which is the child of the scsi_device) prevents the data structures from being released, even though they are deregistered okay. It's possible that this change will cause a few bugs to surface, things that have been hidden for several years. They can be fixed easily enough by having the child device take an explicit reference to the parent whenever needed.

An object's reference count may only be incremented if -it is already positive. - -When a kobject's reference count reaches 0, the method struct -kobj_type::release() (which the kobject's kset points to) is called. -This allows any memory allocated for the object to be freed. - - -NOTE!!! - -It is _imperative_ that you supply a destructor for dynamically -allocated kobjects to free them if you are using kobject reference -counts.

If someone else is referencing the object -(e.g. through a sysfs file), they will obtain a reference to the -object, assume it's valid and operate on it.

Dealing with kobjects requires understanding a few different types, +all of which make reference to each other. In an attempt to make things +easier, we'll take a multi-pass approach, starting with vague terms and +adding detail as we go. To that end, here are some quick definitions of +some terms we will be working with. + + - A kobject is an object of type struct kobject. Kobjects have a name + and a reference count. A kobject also has a parent pointer (allowing + objects to be arranged into hierarchies), a specific type, and, + usually, a representation in the sysfs virtual filesystem. + + Kobjects are generally not interesting on their own; instead, they are + usually embedded within some other structure which contains the stuff + the code is really interested in. + + No structure should EVER have more than one kobject embedded within it. + If it does, the reference counting for the object is sure to be messed + up and incorrect, and your code will be buggy. So do not do this. + + - A ktype is the type of object that embeds a kobject. Every structure + that embeds a kobject needs a corresponding ktype. The ktype controls + what happens to the kobject when it is created and destroyed. + + - A kset is a group of kobjects. These kobjects can be of the same ktype + or belong to different ktypes. The kset is the basic container type for + collections of kobjects. Ksets contain their own kobjects, but you can + safely ignore that implementation detail as the kset core code handles + this kobject automatically. + + When you see a sysfs directory full of other directories, generally each + of those directories corresponds to a kobject in the same kset. + +We'll look at how to create and manipulate all of these types. A bottom-up +approach will be taken, so we'll go back to kobjects. + + +Embedding kobjects + +It is rare for kernel code to create a standalone kobject, with one major +exception explained below. Instead, kobjects are used to control access to +a larger, domain-specific object. To this end, kobjects will be found +embedded in other structures. If you are used to thinking of things in +object-oriented terms, kobjects can be seen as a top-level, abstract class +from which other classes are derived. A kobject implements a set of +capabilities which are not particularly useful by themselves, but which are +nice to have in other objects. The C language does not allow for the +direct expression of inheritance, so other techniques - such as structure +embedding - must be used. + +So, for example, the UIO code has a structure that defines the memory +region associated with a uio device: + +struct uio_mem { + struct kobject kobj; + unsigned long addr; + unsigned long size; + int memtype; + void __iomem *internal_addr; +}; + +If you have a struct uio_mem structure, finding its embedded kobject is +just a matter of using the kobj member. Code that works with kobjects will +often have the opposite problem, however: given a struct kobject pointer, +what is the pointer to the containing structure? You must avoid tricks +(such as assuming that the kobject is at the beginning of the structure) +and, instead, use the container_of() macro, found in : + + container_of(pointer, type, member) + +where pointer is the pointer to the embedded kobject, type is the type of +the containing structure, and member is the name of the structure field to +which pointer points. The return value from container_of() is a pointer to +the given type. So, for example, a pointer "kp" to a struct kobject +embedded within a struct uio_mem could be converted to a pointer to the +containing uio_mem structure with: + + struct uio_mem *u_mem = container_of(kp, struct uio_mem, kobj); + +Programmers often define a simple macro for "back-casting" kobject pointers +to the containing type. + + +Initialization of kobjects + +Code which creates a kobject must, of course, initialize that object. Some +of the internal fields are setup with a (mandatory) call to kobject_init(): + + void kobject_init(struct kobject *kobj, struct kobj_type *ktype); + +The ktype is required for a kobject to be created properly, as every kobject +must have an associated kobj_type. After calling kobject_init(), to +register the kobject with sysfs, the function kobject_add() must be called: + + int kobject_add(struct kobject *kobj, struct kobject *parent, const char *fmt, ...); + +This sets up the parent of the kobject and the name for the kobject +properly. If the kobject is to be associated with a specific kset, +kobj->kset must be assigned before calling kobject_add(). If a kset is +associated with a kobject, then the parent for the kobject can be set to +NULL in the call to kobject_add() and then the kobject's parent will be the +kset itself. + +As the name of the kobject is set when it is added to the kernel, the name +of the kobject should never be manipulated directly. If you must change +the name of the kobject, call kobject_rename(): + + int kobject_rename(struct kobject *kobj, const char *new_name); + +There is a function called kobject_set_name() but that is legacy cruft and +is being removed. If your code needs to call this function, it is +incorrect and needs to be fixed. + +To properly access the name of the kobject, use the function +kobject_name(): + + const char *kobject_name(const struct kobject * kobj); + +There is a helper function to both initialize and add the kobject to the +kernel at the same time, called supprisingly enough kobject_init_and_add(): + + int kobject_init_and_add(struct kobject *kobj, struct kobj_type *ktype, + struct kobject *parent, const char *fmt, ...); + +The arguments are the same as the individual kobject_init() and +kobject_add() functions described above. + + +Uevents + +After a kobject has been registered with the kobject core, you need to +announce to the world that it has been created. This can be done with a +call to kobject_uevent(): + + int kobject_uevent(struct kobject *kobj, enum kobject_action action); + +Use the KOBJ_ADD action for when the kobject is first added to the kernel. +This should be done only after any attributes or children of the kobject +have been initialized properly, as userspace will instantly start to look +for them when this call happens. + +When the kobject is removed from the kernel (details on how to do that is +below), the uevent for KOBJ_REMOVE will be automatically created by the +kobject core, so the caller does not have to worry about doing that by +hand. + + +Reference counts + +One of the key functions of a kobject is to serve as a reference counter +for the object in which it is embedded. As long as references to the object +exist, the object (and the code which supports it) must continue to exist. +The low-level functions for manipulating a kobject's reference counts are: + + struct kobject *kobject_get(struct kobject *kobj); + void kobject_put(struct kobject *kobj); + +A successful call to kobject_get() will increment the kobject's reference +counter and return the pointer to the kobject. + +When a reference is released, the call to kobject_put() will decrement the +reference count and, possibly, free the object. Note that kobject_init() +sets the reference count to one, so the code which sets up the kobject will +need to do a kobject_put() eventually to release that reference. + +Because kobjects are dynamic, they must not be declared statically or on +the stack, but instead, always allocated dynamically. Future versions of +the kernel will contain a run-time check for kobjects that are created +statically and will warn the developer of this improper usage. + +If all that you want to use a kobject for is to provide a reference counter +for your structure, please use the struct kref instead; a kobject would be +overkill. For more information on how to use struct kref, please see the +file Documentation/kref.txt in the Linux kernel source tree. + + +Creating "simple" kobjects + +Sometimes all that a developer wants is a way to create a simple directory +in the sysfs hierarchy, and not have to mess with the whole complication of +ksets, show and store functions, and other details. This is the one +exception where a single kobject should be created. To create such an +entry, use the function: + + struct kobject *kobject_create_and_add(char *name, struct kobject *parent); + +This function will create a kobject and place it in sysfs in the location +underneath the specified parent kobject. To create simple attributes +associated with this kobject, use: + + int sysfs_create_file(struct kobject *kobj, struct attribute *attr); +or + int sysfs_create_group(struct kobject *kobj, struct attribute_group *grp); + +Both types of attributes used here, with a kobject that has been created +with the kobject_create_and_add(), can be of type kobj_attribute, so no +special custom attribute is needed to be created. + +See the example module, samples/kobject/kobject-example.c for an +implementation of a simple kobject and attributes. + + + +ktypes and release methods + +One important thing still missing from the discussion is what happens to a +kobject when its reference count reaches zero. The code which created the +kobject generally does not know when that will happen; if it did, there +would be little point in using a kobject in the first place. Even +predictable object lifecycles become more complicated when sysfs is brought +in as other portions of the kernel can get a reference on any kobject that +is registered in the system. + +The end result is that a structure protected by a kobject cannot be freed +before its reference count goes to zero. The reference count is not under +the direct control of the code which created the kobject. So that code must +be notified asynchronously whenever the last reference to one of its +kobjects goes away. + +Once you registered your kobject via kobject_add(), you must never use +kfree() to free it directly. The only safe way is to use kobject_put(). It +is good practice to always use kobject_put() after kobject_init() to avoid +errors creeping in. + +This notification is done through a kobject's release() method. Usually +such a method has a form like: + + void my_object_release(struct kobject *kobj) + { + struct my_object *mine = container_of(kobj, struct my_object, kobj); + + /* Perform any additional cleanup on this object, then... */ + kfree(mine); + } + +One important point cannot be overstated: every kobject must have a +release() method, and the kobject must persist (in a consistent state) +until that method is called. If these constraints are not met, the code is +flawed. Note that the kernel will warn you if you forget to provide a +release() method. Do not try to get rid of this warning by providing an +"empty" release function; you will be mocked mercilessly by the kobject +maintainer if you attempt this. + +Note, the name of the kobject is available in the release function, but it +must NOT be changed within this callback. Otherwise there will be a memory +leak in the kobject core, which makes people unhappy. + +Interestingly, the release() method is not stored in the kobject itself; +instead, it is associated with the ktype. So let us introduce struct +kobj_type: + + struct kobj_type { + void (*release)(struct kobject *); + struct sysfs_ops *sysfs_ops; + struct attribute **default_attrs; + }; + +This structure is used to describe a particular type of kobject (or, more +correctly, of containing object). Every kobject needs to have an associated +kobj_type structure; a pointer to that structure must be specified when you +call kobject_init() or kobject_init_and_add(). + +The release field in struct kobj_type is, of course, a pointer to the +release() method for this type of kobject. The other two fields (sysfs_ops +and default_attrs) control how objects of this type are represented in +sysfs; they are beyond the scope of this document. + +The default_attrs pointer is a list of default attributes that will be +automatically created for any kobject that is registered with this ktype. + + +ksets + +A kset is merely a collection of kobjects that want to be associated with +each other. There is no restriction that they be of the same ktype, but be +very careful if they are not. + +A kset serves these functions: + + - It serves as a bag containing a group of objects. A kset can be used by + the kernel to track "all block devices" or "all PCI device drivers." + + - A kset is also a subdirectory in sysfs, where the associated kobjects + with the kset can show up. Every kset contains a kobject which can be + set up to be the parent of other kobjects; the top-level directories of + the sysfs hierarchy are constructed in this way. + + - Ksets can support the "hotplugging" of kobjects and influence how + uevent events are reported to user space. + +In object-oriented terms, "kset" is the top-level container class; ksets +contain their own kobject, but that kobject is managed by the kset code and +should not be manipulated by any other user. + +A kset keeps its children in a standard kernel linked list. Kobjects point +back to their containing kset via their kset field. In almost all cases, +the kobjects belonging to a ket have that kset (or, strictly, its embedded +kobject) in their parent. + +As a kset contains a kobject within it, it should always be dynamically +created and never declared statically or on the stack. To create a new +kset use: + struct kset *kset_create_and_add(const char *name, + struct kset_uevent_ops *u, + struct kobject *parent); + +When you are finished with the kset, call: + void kset_unregister(struct kset *kset); +to destroy it. + +An example of using a kset can be seen in the +samples/kobject/kset-example.c file in the kernel tree. + +If a kset wishes to control the uevent operations of the kobjects +associated with it, it can use the struct kset_uevent_ops to handle it: + +struct kset_uevent_ops { + int (*filter)(struct kset *kset, struct kobject *kobj); + const char *(*name)(struct kset *kset, struct kobject *kobj); + int (*uevent)(struct kset *kset, struct kobject *kobj, + struct kobj_uevent_env *env); +}; + + +The filter function allows a kset to prevent a uevent from being emitted to +userspace for a specific kobject. If the function returns 0, the uevent +will not be emitted. + +The name function will be called to override the default name of the kset +that the uevent sends to userspace. By default, the name will be the same +as the kset itself, but this function, if present, can override that name. + +The uevent function will be called when the uevent is about to be sent to +userspace to allow more environment variables to be added to the uevent. + +One might ask how, exactly, a kobject is added to a kset, given that no +functions which perform that function have been presented. The answer is +that this task is handled by kobject_add(). When a kobject is passed to +kobject_add(), its kset member should point to the kset to which the +kobject will belong. kobject_add() will handle the rest. + +If the kobject belonging to a kset has no parent kobject set, it will be +added to the kset's directory. Not all members of a kset do necessarily +live in the kset directory. If an explicit parent kobject is assigned +before the kobject is added, the kobject is registered with the kset, but +added below the parent kobject. + + +Kobject removal + +After a kobject has been registered with the kobject core successfully, it +must be cleaned up when the code is finished with it. To do that, call +kobject_put(). By doing this, the kobject core will automatically clean up +all of the memory allocated by this kobject. If a KOBJ_ADD uevent has been +sent for the object, a corresponding KOBJ_REMOVE uevent will be sent, and +any other sysfs housekeeping will be handled for the caller properly. + +If you need to do a two-stage delete of the kobject (say you are not +allowed to sleep when you need to destroy the object), then call +kobject_del() which will unregister the kobject from sysfs. This makes the +kobject "invisible", but it is not cleaned up, and the reference count of +the object is still the same. At a later time call kobject_put() to finish +the cleanup of the memory associated with the kobject. + +kobject_del() can be used to drop the reference to the parent object, if +circular references are constructed. It is valid in some cases, that a +parent objects references a child. Circular references _must_ be broken +with an explicit call to kobject_del(), so that a release functions will be +called, and the objects in the former circle release each other. + + +Example code to copy from + +For a more complete example of using ksets and kobjects properly, see the +sample/kobject/kset-example.c code. -- cgit v0.10.2 From 40efcb05f213180b7cc8fd8d963377305f236c28 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 27 Nov 2007 11:28:26 -0800 Subject: kobject: add sample code for how to use kobjects in a simple manner.

This patch adds a call to this hook when handling a PTRACE_TRACEME request as well. Currently only one architecture, m32r, implements this hook. When called, it initializes a number of debug trap slots in the ptraced task's thread struct, and it looks to me like this is the right thing to do after a PTRACE_TRACEME request as well, not only after PTRACE_ATTACH. Please correct me if I'm wrong. I want to use this hook on AVR32 to turn the debugging hardware on when a process is actually being debugged and keep it off otherwise. To be able to do this, I need to intercept PTRACE_TRACEME and PTRACE_ATTACH, as well as PTRACE_DETACH and thread exit. The latter two can be handled by existing hooks.

Since enabling debugging turns off some optimizations in the CPU core, this fixes the issue that enabling KProbes support or simply running a program under gdbserver will reduce system performance significantly until the next reboot. The CPU performance will still be reduced for all processes while a process is being debugged, but this is a lot better than reducing the performance forever.

Show chip type and revision at bootup, and clarify that the other kinds of IDs that we're already printing are for the cpu core and architecture. Rename "AP7000" to "AP7" since that's the name of the core.

Actual start/stop of the pipeline is moved to the driver's kernel thread. Pipeline stages are controlled autonomously based on surrounding pipeline or application control state. Kernel thread management is also cleaned up and moved into the internal control structure of the driver, solving a set up / tear down race along the way. Better failure recovery is implemented with this new control strategy. Also with this change comes better control of the cx23416 encoder, building on additional information learned about the peculiarities of controlling this part (this information was the original trigger for this rework). With this change, overall encoder stability should be considerably improved. Yes, this is a large change for this driver, but due to the nature of the feature being worked on, the changes are fairly pervasive and would be difficult to break into smaller pieces with any semblence of step-wise stability.

However there are other hardware types potentially supportable, but the driver at the moment is not structured to make it easy to describe these minor variations. This changeset is the first set of changes to make such additional device support possible. Device attributes are held in several tables all contained within pvrusb2-devattr.c; all other device-specific driver behavior now derives from these tables.

Hauppauge devices do it one way; other types of device may route things differently. Unfortunately it is rather impractical to define chip-specific routing at the device attribute level, so instead what happens here is that "schemes" are defined. Each chip level interface implements its part of a given scheme and the scheme as a whole is made into a device specific attribute controlled via a table entry in pvrusb2-devattr.c. The only scheme defined here is for Hauppauge devices, but clearly this opens the door for other possibilities to follow.

However, the standard can be changed after the init phase. This effectively breaks the yuv output stream handler, since it relies on the different yuv planes being block aligned. This patch changes the setup, so that the block size is always the same. The decoder dma function has been modified to cope with the fact that the second yuv plane may no longer be block aligned. The start of the yuv frame must still be at the beginning of a block, so the stream write function has also been modified to ensure this is always true. Also, the stream write function will now initiate a yuv dma transfer as soon as a full frame is ready. It will not wait until the current write request has completed, or the stream buffer becomes full.

Given that it can affect how a new frame is displayed, it was a bit stupid running it after the frame was already visible. A few stray interlace related variables which were linked to individual frames have now been moved into the yuv_frame_info struct. This means that all variables linked to a specific frame are in the same place & not scattered. Minor code reformatting in areas touched by the above changes.

With this patch, yuv frames written to video48 are now handled by the existing IVTV_IOC_DMA_FRAME framework. As such, the frames are hardware buffered to avoid tearing, and honour scaling mode & field order options. Unlike the proprietary IVTV_IOC_DMA_FRAME ioctl, all parameters are controlled by the V4L2 API. Due to mpeg & yuv output restrictions being different, their V4L2 output controls have been separated. To control the yuv output, the V4L2 calls must be done via video48. If the ivtvfb module is loaded, there will be one side effect to this merge. The yuv output window will be constrained to the visible framebuffer area. In the event that a virtual framebuffer size is being used, the limit to the output size will be the virtual dimensions, but only the portion that falls within the currently visible area of the framebuffer will be shown. Like the IVTV_IOC_DMA_FRAME ioctl, the supplied frames must be padded to 720 pixels wide. However the height must only be padded up the nearest multiple of 32. This would mean an image of 102 lines must be padded to 128. As long as the true source image size is given, the padding will not be visible in the final output.

This where due to not properly preserving the minor inode after calling video_register. Since this driver is a reference for newer drivers, and it is possible to have more than one video device inside the machine, this patch makes vivi to dynamically allocate video_device struct.

Especially mythtv users would find that the audio would often sound bad (aliased, or 'raspy'), mainly related to channel changes, many (all?) other users would find that there was no audio at all in the mpeg data from the encoder chip, unless the audio was manually unmuted. The patch includes the following modifications: Don't actually start the mpeg2 encoder until the device is read from by the application. Wait until the audio is stable for at least 400ms before starting the mpeg encoder. Mute/Unmute the audio when starting/stopping the mpeg encoder. Stop the mpeg encoder when changing parameters and when changing tuner frequency. Add a variable 'mpeg_active' to struct cx8802_dev to allow tracking of whether or not the mpeg2 encoder is active. Load the firmware on cx88-blackbird driver load.

I've tested with other ATSC tuners just to confirm, using: us-ATSC-center-frequencies-8VSB Anyhow, as it turns out, the tuner-xc2028 *does* require a tuning offset for ATSC. Even though the linux-dvb api passes in center frequencies from userspace, apparantly the xceive firmware is already factoring in the tuning offset to center. In order to make the device function using the same scan files / channels.conf configurations as other atsc devices, we must offset by 1.75 MHz.

However, on newer devices, this were replaced by a Vendor Class. This patch autodetects that an em28xx lacks Audio Class and auto-loads em28xx-alsa, for the devices that implements only a Vendor Class. For devices with Audio Class, snd-usb-audio module will provide an ALSA interface. This patch uses the request_module_async function as defined on cx88-mpeg.c, originally wrote by Markus Rechberger.

It should also work for the identical ADS/Tech FM Radio Receiver (formerly Instant FM Music) as soon as I find out the USB Vendor and Product ID. The driver is inspired by several other USB and radio drivers, but mainly from the D-Link DSB-R100 USB radio (dsbr100.c). The USB stick currently has an Si4701 FM RDS radio receiver. But the other Si470x devices are pin and register compatible, so that in the future the driver can easily be patched to support these too. Therefore I named the driver radio-si470x and the configuration option usb-si470x. The driver itself just provides the control function over the radio. For getting audio back, the device support the USB audio class, which is implemented in the already existing driver. I tested the driver in the last days, until it now satisfies all my functionality and robustness requirements. The application I used for testing was kradio.

Having two ways to say that a tuner is not present is not nice, since it may lead to bad setups. In fact, with the previous code, if a device were using has_tuner=0, but the user forces a tuner, with modprobe option tuner=type, the modprobe option won't work. Also, tveeprom returns TUNER_ABSENT, when tuner is unknown or absent. So, with the previous logic, in this case, the driver should set has_tuner=0, or has_tuner=1 otherwise. Instead of adding several additional tests and setups, better just to remove .has_tuner.

Check it instead of ->tf_out_flags.all. * Add IDE_TFLAG_OUT_DATA taskfile flag to indicate the need to load IDE data register in ide_tf_load(). * Add IDE_TFLAG_OUT_* taskfile flags to indicate the need to load particular IDE taskfile registers in ide_tf_load(). * Update do_rw_taskfile() and ide_tf_load() users to set respective IDE_TFLAG_OUT_* taksfile flags. * Add task_dma_ok() helper. * Use IDE_TFLAG_FLAGGED taskfile flag to select HIHI mask in ide_tf_load(). * Use do_rw_taskfile() in flagged_taskfile(). * Remove no longer needed 'tf_out_flags' field from ide_task_t.

The current IPoIB connected mode support only works on devices that support SRQs. Fix this by adding support for using the receive queue of each connected mode receive QP. The disadvantage of this compared to using an SRQ is that it means a full queue of receives must be posted for each remote connected mode peer, which means that total memory usage is potentially much higher than when using SRQs. To manage this, add a new module parameter "max_nonsrq_conn_qp" that limits the number of connections allowed per interface. The rest of the changes are fairly straightforward: we use a table of struct ipoib_cm_rx to hold all the active connections, and put the table index of the connection in the high bits of receive WR IDs. This is needed because we cannot rely on the struct ib_wc.qp field for non-SRQ receive completions. Most of the rest of the changes just test whether or not an SRQ is available, and post receives or find received packets in the right place depending on the answer. Cleaning up dead connections actually becomes simpler, because we do not have to do the "last WQE reached" dance that is required to destroy QPs attached to an SRQ. We just move the QP to the error state and wait for all pending receives to be flushed. Signed-off-by: Pradeep Satyanarayana [ Completely rewritten and split up, based on Pradeep's work.

However, the structures on these two lists are not the same. The wait_list references struct ib_mad_send_wr_private, but local_list references struct ib_mad_local_private. Cancel_mads() treats all items moved to the cancel_list as struct ib_mad_send_wr_private. This leads to a system crash when requests are moved from the local_list to the cancel_list. Fix this by leaving local_list alone. All requests on the local_list have completed are just awaiting processing by a queued worker thread. Bug (crash) reported by Dotan Barak .

Connection request events are reported on the event channel associated with the listen. When the connection is accepted, a new rdma_cm_id is created and automatically uses the listen event channel. This is suboptimal where the user only wants listen events on that channel. Additionally, it may be desirable to have events related to connection establishment use a different event channel than those related to already established connections. Allow the user to migrate an rdma_cm_id between event channels. All pending events associated with the rdma_cm_id are moved to the new event channel.

The existing routines that map IP/IPv6 multicast addresses into IB link-level addresses hard-code the scope to link-local, and they also leave the partition key field uninitialised. This patch adds a parameter (the link-level broadcast address) to the mapping routines, allowing them to initialise both the scope and the P_Key appropriately, and fixes up the call sites. The next step will be to add a way to configure the scope for an IPoIB interface.

The results of sending extra requests are vendor specific, but on some devices, overrunning credits will cost 85% of peak performance -- e.g. 100 MB/s vs 720 MB/s. Other devices may just drop the requests. This patch will tell the SCSI midlayer to queue requests if there are fewer than two credits remaining, and will not issue a task management request if there are no credits remaining. The mid-layer will retry the queued command once an outstanding command completes. The patch also removes the unlikely() in __srp_get_tx_iu(), as it is not at all unlikely to hit this limit under heavy load.

By allowing the mid-layer to chain requests, we can easily grow to 1024KB or larger -- I've tested 4096KB I/O requests with no problems. I looked through the DMA paths on the hardware drivers to ensure they could take advantage of the SG chaining, and it seems that every one except ipath uses the system's DMA routines, which have been converted to handle chaining. ipath looks like it should be OK, but I have no way to test it.

The passive side may override this value when accepting the connection. Use the value provided by the passive side when transitioning the QP to RTR state, rather than the value given in the connect request. Without this change, the RTR transition may fail if the passive side supports fewer responder_resources than that in the request. For code consistency and to protect against QP destruction, restructure overriding initiator_depth to match how responder_resources is set.

In particular it seems that a single thread may end up trying to take the same rwsem for reading more than once, which is explicitly forbidden in the comments in . To solve this, we change the locking to use plain mutexes instead of rwsems. There is one mutex per open file, which protects the contents of the struct ib_umad_file, including the array of agents and list of queued packets; and there is one mutex per struct ib_umad_port, which protects the contents, including the list of open files. We never hold the file mutex across calls to functions like ib_unregister_mad_agent(), which can call back into other ib_umad code to queue a packet, and we always hold the port mutex as long as we need to make sure that a device is not hot-unplugged from under us. This even makes things nicer for users of the -rt patch, since we remove calls to downgrade_write() (which is not implemented in -rt).

However, if the FMR pool flushes dirty FMRs because the dirty_watermark was reached, we wake up the cleanup thread and let it do its stuff. As a side effect, the cleanup thread increments pool->flush_ser, which leaves it one higher than pool->req_ser. The next time the user calls ib_flush_fmr_pool(), the cleanup thread will be woken up, but ib_flush_fmr_pool() won't wait for the flush to complete because flush_ser is already past req_ser. This means the FMRs that the user expects to be flushed may not have all been flushed when the function returns. Fix this by telling the cleanup thread to do work exclusively by incrementing req_ser, and by moving the comparison of dirty_len and dirty_watermark into ib_fmr_pool_unmap().

However, ib_fmr_batch_release() only looks at dirty_list when flushing out old mappings. This means that when ib_fmr_pool_flush() is used to force a flush of the FMR pool, some dirty FMRs that have not reached their maximum remap count will not actually be flushed. Fix this by flushing all FMRs that have been used at least once in ib_fmr_batch_release().

In order to utilize that function the module option nr_ports must be set to -1 (default is 2 - two ports). This feature is experimental and will made the default later. More detail: If the user connects only one port to the switch, current code requires 1) port one to be connected and 2) module option nr_ports=1 to be given. If autodetect is enabled, ehca will not wait at creation of the GSI QP for the respective port to become active. Since firmware does not accept modify_qp() while the port is down at initialization, we need to cache all calls to modify_qp() for the SMI/GSI QP and just return a good return code. When a port is activated and we get a PORT_ACTIVE event, we replay the cached modify-qp() parms and re-trigger any posted recv WRs. Only then do we forward the PORT_ACTIVE event to registered clients. The result of this autodetect patch is that all ports will be accessible by the users. Depending on their respective cabling only those ports that are connected properly will become operable. If a user tries to modify a regular QP of a non-connected port, modify_qp() will fail. Furthermore, ibv_devinfo should show the port state accordingly. Note that this patch primarily improves the loading behaviour of ehca. If the cable is removed while the driver is operating and plugged in again, firmware will handle that properly by sending an appropriate async event.

This can be prevented by assuring that, after the first RDMA Read, the QP receives a new RDMA Read every few million link packets.

This means that ipoib_start_xmit() no longer needs to test netif_queue_stopped(); the test was added to fix earlier kernels, where the networking stack did not guarantee that the xmit method of an LLTX driver would not be called after the queue was stopped, but current kernels do provide this guarantee.

This value is initialized from global_bitmap->id2.i_chain.cl_cpg. If there is only 1 group, it will be equal to the total clusters in the volume. So as for online resize, it should change for all the nodes in the cluster. It isn't easy and there is no corresponding lock for it. bitmap_cpg is only used in 2 areas: 1. Check whether the suballoc is too large for us to allocate from the global bitmap, so it is little used. And now the suballoc size is 2048, it rarely meet this situation and the check is almost useless. 2. Calculate which group a cluster belongs to. We use it during truncate to figure out which cluster group an extent belongs too. But we should be OK if we increase it though as the cluster group calculated shouldn't change and we only ever have a small bitmap_cpg on file systems with a single cluster group.

The request is made via an ioctl, OCFS2_IOC_GROUP_ADD. On a high level, this is similar to ext3, but we use a different ioctl as the structure which has to be passed through is different. During an online resize, tunefs.ocfs2 will format any new cluster groups which must be added to complete the resize, and call OCFS2_IOC_GROUP_ADD on each one. Kernel verifies that the core cluster group information is valid and then does the work of linking it into the global allocation bitmap.

Since these locks are driven from userspace, usage rules are much more liberal than the typical Ocfs2 internal cluster lock. As a result, we can't make use of most dlmglue features - lock caching and lock level optimizations in particular. Additionally, userspace is free to deadlock itself, so we have to deal with that in the same way as the rest of the kernel - by allowing a signal to abort a lock request. In order to keep ocfs2_cluster_lock() complexity down, ocfs2_file_lock() does it's own dlm coordination. We still use the same helper functions though, so duplicated code is kept to a minimum.

After query join, the joined node will set its joining_node. So if the joining node happens to panic before the 2nd step, the joined node will fail to clear its joining_node flag because that node isn't in the domain map. It at least cause 2 problems. 1. All the new join request will fail. So no new node can mount the volume. 2. The joined node can't umount the volume since during the umount process it has to wait for the joining_node to be unknown. So the umount will be hanged. The solution is to clear the joining_node before we check the domain map.

Add a new interface so that cpus can be put into standby state and configured state. Only offline cpus can be put into standby state or configured state. For that the new percpu sysfs attribute "configure" must be used. To put a cpu in standby state a "0" must be written to the attribute. In order to switch it into configured state a "1" must be written to the attribute. Only cpus in configured state can be brought online. In addition this patch introduces a static mapping of physical to logical cpus. As a result only the sysfs directories of present cpus will be created. To scan for new cpus the new sysfs attribute "rescan" must be used. Writing to /sys/devices/system/cpu/rescan will trigger a rescan of cpus and will create directories for new cpus. On IPL only configured cpus will be used. And on reboot/shutdown all cpus will remain in their current state (configured/standby).

The clear-by-asce operation of the idte instruction gets an asce (address-space-control-element) as argument to specify which TLBs need to get flushed. The current code passes a plain pointer to the start of the pgd without the additional bits which would make the pointer an asce. The current machines don't mind the difference but a future model might want to use the designation type control bits in the asce as a filter for the TLBs to flush.

Virtual sysfs files under the directory /sys/firmware/ are used for that configuration. In addition to that, there are kernel parameters 'vmhalt', 'vmpoff' and 'vmpanic', which can be used to specify z/VM commands, which are automatically executed in case of halt, power off or a kernel panic. This patch combines both functionalities and allows to specify the z/VM CP commands also via sysfs attributes. In addition to that, it enhances the existing handling of shutdown triggers (e.g. halt or panic) and associated shutdown actions (e.g. dump or reipl) and makes it more flexible.

The vmemmap code has already created the 1:1 mapping but failed allocating the struct pages. In the OOM case, show_mem now walks the memory. It uses pfn_valid to detect if it may access the struct page. In the case described above, the mapping was established and pfn_valid returned true. As the struct pages were not allocated, the kernel oopsed. We have to ensure that we have created the struct pages, before we add a mapping pointing to the pages.

This patch fixes a problem with the following scenario: 1. Linux booted from DASD "A" 2. Reboot from DASD "B" using "/sys/firmware/reipl/ccw/device" 3. Reboot DASD "B" Without this patch in step 3 on newer s390 systems under LPAR instead of DASD "B", DASD "A" will be booted. The reason is that in step 2 we use CCW reipl and in step 3 we use DIAG308 (subcode 3) reipl. DIAG308 does not notice the CCW reipl and still thinks that it has to reboot DASD "A".

It defines alias devices which can be used as alternative paths to the same disk. With the old base PAV support we only needed rudimentary functionality in the DASD device driver. As the mapping between base and alias devices was static, we just had to export an identifier (uid) and could leave the combining of devices to external layers like a device mapper multipath. Now hyper PAV removes the requirement to dedicate alias devices to specific base devices. Instead each alias devices can be combined with multiple base device on a per request basis. This requires full support by the DASD device driver as now each channel program itself has to identify the target base device. The changes to the dasd device driver and the ECKD discipline are: - Separate subchannel device representation (dasd_device) from block device representation (dasd_block). Only base devices are block devices. - Gather information about base and alias devices and possible combinations. - For each request decide which dasd_device should be used (base or alias) and build specific channel program. - Support summary unit checks, which allow the storage server to upgrade / downgrade between base and hyper PAV at runtime (support is mandatory).

In s390's spin_lock_irqsave, interrupts remain disabled while spinning. In other architectures like x86 and powerpc, interrupts are re-enabled while spinning if IRQ is not masked before spin_lock_irqsave is called.

This simplifies code such as #define IRQ_EP93XX_GPIO(x) (64 + (((x) + (((x) >> 2) & 8)) & 0x1f)) or if (line >= 0 && line < 16) { /* Port A/B */ } else if (line >= 40 && line < 48) { /* Port F */ } considerably; in addition to the renumbering this patch also introduces macro constants EP93XX_GPIO_LINE_MAX_IRQ and EP93XX_GPIO_LINE_MAX, and replaces most magic numbers by those and invocations of gpio_to_irq()/irq_to_gpio().

-- cgit v0.10.2 From 9e73c84c89b7c91ad5d6a141c58efbbe139f6b6c Mon Sep 17 00:00:00 2001 From: Brian Swetland Date: Mon, 26 Nov 2007 04:12:13 -0800 Subject: [ARM] msm: board file for MACH_HALIBUT (QCT MSM7200A) Add support for the Qualcomm MSM7200A eval board. Common devices are defined in common.c, to avoid excessive cut'n'pasting them into other board files.

It implements support for VFP subarchitecture 2 while being backwards compatible with subarchitecture 1. On VFP subarchitecture 1, the arithmetic exceptions are asynchronous (or imprecise as described in the old ARM ARM) unless the FPSCR.IXE bit is 1. The exceptional instructions can be read from FPINST and FPINST2 registers. With VFP subarchitecture 2, the arithmetic exceptions can also be synchronous and marked by the FPEXC.DEX bit (the FPEXC.EX bit is cleared). CPUs implementing the synchronous arithmetic exceptions don't have the FPINST and FPINST2 registers and accessing them would trigger and undefined exception. Note that FPEXC.EX bit has an additional meaning on subarchitecture 1 - if it isn't set, there is no additional information in FPINST and FPINST2 that needs to be saved at context switch or when lazy-loading the VFP state of a different thread. The patch also removes the clearing of the cumulative exception flags in FPSCR when additional exceptions were raised. It is up to the user application to clear these bits.

The NEON technology is a 64/128-bit hybrid SIMD architecture for accelerating the performance of multimedia and signal processing applications. The extension shares the registers with the VFP unit and enabling/disabling and saving/restoring follow the same rules. In addition, there are instructions that do not have the appropriate CP number encoded, the checks being made in the call_fpe function.
