The reason for that is that during the refactoring of the off- channel code, I lost the part that stopped all activity and as a consequence the on-channel frames (including data frames) were no longer queued but would be transmitted on the temporary channel.

This should fix the regression caused by commit bc0bb9fd1c7810407ab810d204bbaecb255fddde Author: Jani Nikula Date: Thu Nov 14 12:14:29 2013 +0200 drm/i915: remove QUIRK_NO_PCH_PWM_ENABLE AFAICT the quirk removed by the above commit effectively resulted in i915 not driving the backlight PWM output, thus not messing things up. Additionally this should fix the regression caused by commit fbc9fe1b4f222a7c575e3bd8e9defe59c6190a04 Author: Aaron Lu Date: Fri Oct 11 21:27:45 2013 +0800 ACPI / video: Do not register backlight if win8 and native interface exists which left some machines without a functioning backlight interface.

If we always initialize kref for the context, even if we are using fake contexts for hangstats when there is no hw support, we can forgo the dance to dereference the ctx->obj and inspect whether we are permitted to use kref inside i915_gem_context_reference() and _unreference(). My ulterior motive here is to improve the debugging of a use-after-free of ctx->obj. This patch avoids the dereference here and instead forces the assertion checks associated with kref. v2: Refactor the fake contexts to being even more like the real contexts, so that there is much less duplicated and special case code. v3: Tweaks. v4: Tweaks, minor.

The processing of terminal input requires prior initialization which is done via an early_initcall function (init_workqueues) while the SCLP VT220 driver registers for terminal input during a console_initcall function (sclp_vt220_con_init). When there is terminal input available via the SCLP interface between console_initcall and early_initcall, a null pointer dereference occurs (system_wq is null). Fix this problem by moving the registration for terminal input to a device_initcall function (sclp_vt220_tty_init).

If there are continual CPL messages flowing into the driver, the endpoint timeout processing can be starved. This condition exposed the other bugs below. Solution: In process_work(), call process_timedout_eps() after each CPL is processed. 2) Connection events can be processed even though the endpoint is on the timeout list. If the endpoint is scheduled for timeout processing, then we must ignore MPA Start Requests and Replies. Solution: Change stop_ep_timer() to return 1 if the ep has already been queued for timeout processing. All the callers of stop_ep_timer() need to check this and act accordingly. There are just a few cases where the caller needs to do something different if stop_ep_timer() returns 1: 1) in process_mpa_reply(), ignore the reply and process_timeout() will abort the connection. 2) in process_mpa_request, ignore the request and process_timeout() will abort the connection. It is ok for callers of stop_ep_timer() to abort the connection since that will leave the state in ABORTING or DEAD, and process_timeout() now ignores timeouts when the ep is in these states. 3) Double insertion on the timeout list. Since the endpoint timers are used for connection setup and teardown, we need to guard against the possibility that an endpoint is already on the timeout list. This is a rare condition and only seen under heavy load and in the presense of the above 2 bugs. Solution: In ep_timeout(), don't queue the endpoint if it is already on the queue.

The SQ work request will never get processed, and should be completed with FLUSHED status. Function c4iw_flush_sq(), however was dropping the oldest SQ work request when in CLOSING or IDLE states, instead of completing the pending work request. If that oldest pending work request was actually complete and has a CQE in the CQ, then when that CQE is proceessed in poll_cq, we'll BUG_ON() due to the inconsistent SQ/CQ state. This is a very small timing hole and has only been hit once so far. The fix is two-fold: 1) c4iw_flush_sq() MUST always flush all non-completed WRs with FLUSHED status regardless of the QP state. 2) In c4iw_modify_rc_qp(), always set the "in error" bit on the queue before moving the state out of RTS. This ensures that the state transition will not happen while another thread is in post_rc_send(), because set_state() and post_rc_send() both aquire the qp spinlock. Also, once we transition the state out of RTS, subsequent calls to post_rc_send() will fail because the "in error" bit is set. I don't think this fully closes the race where the FW can get a FINI followed a SQ work request being posted (because they are posted to differente EQs), but the #1 fix will handle the issue by flushing the SQ work request.

While this commit allows to use the mvneta driver as a module on some configurations, it breaks other configurations even if mvneta is used built-in. This breakage is due to the fact that on some RGMII platforms, the PCS bit has to be set, and on some other platforms, it has to be cleared. At the moment, we lack informations to know exactly the significance of this bit (the datasheet only says "enables PCS"), and so we can't produce a patch that will work on all platforms at this point. And since this change is breaking the network completely for many users, it's much better to revert it for now. We'll come back later with a proper fix that takes into account all platforms. Basically: * Armada XP GP is configured as RGMII-ID, and needs the PCS bit to be set. * Armada 370 Mirabox is configured as RGMII-ID, and needs the PCS bit to be cleared. And at the moment, we don't know how to make the distinction between those two cases. One hint is that the Armada XP GP appears in fact to be using a QSGMII connection with the PHY (Quad-SGMII), but configuring it as SGMII doesn't work, while RGMII-ID works. This needs more investigation, but in the mean time, let's unbreak the network for all those users.

This allows the subtraction of the nla header to underflow and therefore -- as the data type is unsigned -- allowing far to big offset and length values for the search of the netlink attribute. The remainder calculation for the BPF_S_ANC_NLATTR_NEST extension is also wrong. It has the minuend and subtrahend mixed up, therefore calculates a huge length value, allowing to overrun the end of the message while looking for the netlink attribute.

This is incorrect because edma_resume() enables edma events on the channel after which CPU (in edma_start) cannot clear posted events by writing to ECR (per the EDMA user's guide). Because of this EDMA transfers fail to start if due to some reason there is a pending EDMA event registered even before EDMA transfers are started. This can happen if an EDMA event is a byproduct of device initialization. Fix this by calling edma_resume() only if it is not the first batch of MAX_NR_SG elements. Without this patch, MMC/SD fails to function on DA850 EVM with DMA. The behaviour is triggered by specific IP and this can explain why the issue was not reported before (example with MMC/SD on AM335x). Tested on DA850 EVM and AM335x EVM-SK using MMC/SD card.

The page will eventually be released due to some other operation (e.g. direct IO), and it will not pass through invalidation because it is dirty. Hence it will be released with buffer_delay set on it, and trigger warnings in xfs_vm_releasepage() and assert fail in xfs_file_aio_write_direct because invalidation failed and we didn't write the corect amount. This causes failures on block size < page size filesystems in fsx and fsstress workloads run by xfstests. Fix it by completely trashing any state on the buffer that could be used to imply that it contains valid data when the delalloc range over the buffer is punched out during the failed write handling.

This doesn't take into account the fact that we may have already made successful writes to the same page (in the case of block size < page size) and hence we can truncate the page cache away from blocks with valid data in them. If these blocks are delayed allocation blocks, we now have a mismatch between the page cache and the extent tree, and this will trigger - at minimum - a delayed block count mismatch assert when the inode is evicted from the cache. We can also trip over it when block mapping for direct IO - this is the most common symptom seen from fsx and fsstress when run from xfstests. Fix it by only truncating away the exact range we are updating state for in this write_begin call.

For comparisions of size < 4 byte a mask is calculated that is applied to both the data from userspace (during initialization) and the register value (during runtime). Both values are stored using (in effect) memcpy to a memory area that is then interpreted as u32 by nft_cmp_fast. This works fine on little endian since smaller types have the same base address, however on big endian this is not true and the smaller types are interpreted as a big number with trailing zero bytes. The mask therefore must not include the lower bytes, but the higher bytes on big endian. Add a helper function that does a cpu_to_le32 to switch the bytes on big endian.

The driver does disable the sync-lost irq properly, but it fails to wait until the output has been fully enabled (i.e. the first vsync), so the sync-lost errors are still seen occasionally. This patch makes the omapdrm act the same way as the omapfb does: - When enabling a display, we'll wait for the first vsync. - When disabling a display, we'll wait for framedone if available, or odd and even vsyncs.

However, this doesn't work correctly. The encoder driver has to be in control of its video input (i.e. the crtc) for correct operation. This problem causes bugs with (at least) HDMI: the HDMI encoder supplies pixel clock for DISPC, and DISPC supplies video stream for HDMI. The current code first enables the HDMI encoder, and CRTC after that. However, the encoder expects the video stream to start during the encoder's enable, and if it doesn't, there will be sync lost errors. The encoder enables its video source by calling src->enable(), and this call goes to omapdrm (omap_crtc_enable), but omapdrm doesn't do anything in that function. Similarly for disable, which goes to omap_crtc_disable(). This patch moves the code to setup and enable/disable the crtc to omap_crtc_enable. and omap_crtc_disable().

However, the irq handlers presume that the hardware is enabled, which, in theory, may not be the case with shared irq handlers. So if an interrupt happens while the DISPC/DSI is off, the kernel will halt as the irq handler tries to access the DISPC/DSI registers. In practice that should never happen, as both DSI and DISPC are in the same power domain. So if there's an IRQ for one of them, the other is also enabled. However, if CONFIG_DEBUG_SHIRQ is enabled, the kernel will generate a spurious IRQ, which then causes the problem. This patch adds an is_enabled field for both DISPC and DSI, which is used to track if the HW is enabled. For DISPC the code is slightly more complex, as the users of DISPC can register the interrupt handler, and we want to hide the is_enabled handling from the users of DISPC.

This timeout value was roughly calculated based on 10G transmission speeds and the TX queue depth. This timeout may not be enough when the link is operating at lower speeds or in multi-channel/SR-IOV configs with TX-rate limiting setting. It is hard to calculate a "proper timeout value" that works in all configurations. This patch solves this problem by continuing to reap TX completions till the HW is completely silent for a period of 10ms or a HW error is detected. v2: implements the new scheme (as suggested by David Laight) instead of just waiting longer than 200ms for reaping all completions.

After this the stack tries to remove device from bus and calls be_remove() which invokes netdev_unregister()->be_close(). be_close() operating on destroyed queues results in a NULL dereference.

Moreover, Linus reports that x86_64 Chromium seems fine. The underlying issue that explains this is that the implementation of populate_seccomp_data() is wrong. Our seccomp data structure sd that is being shared with user ABI is: struct seccomp_data { int nr; __u32 arch; __u64 instruction_pointer; __u64 args[6]; }; Therefore, a simple cast to 'unsigned long *' for storing the value of the syscall argument via syscall_get_arguments() is just wrong as on 32-bit x86 (or any other 32bit arch), it would result in storing a0-a5 at wrong offsets in args[] member, and thus i) could leak stack memory to user space and ii) tampers with the logic of seccomp BPF programs that read out and check for syscall arguments: syscall_get_arguments(task, regs, 0, 1, (unsigned long *) &sd->args[0]); Tested on 32-bit x86 with Google Chrome, unfortunately only via remote test machine through slow ssh X forwarding, but it fixes the issue on my side. So fix it up by storing args in type correct variables, gcc is clever and optimizes the copy away in other cases, e.g. x86_64.

This seems to happen when forwarding through and OpenSSL tunnel. When we start looking for any vlan headers in skb_network_protocol() we seem to ignore any of the already known mac headers and start with an ETH_HLEN. This results in an incorrect offset, dropped TSO frames and general slowness of the connection.

In this file, there is only control dependency, no data dependecy, so the use of smp_read_barrier_depends() is incorrect. The code could fail in the following way: * the cpu predicts that idx < entries is true and starts executing the body of the for loop * the cpu fetches map->extent[0].first and map->extent[0].count * the cpu fetches map->nr_extents * the cpu verifies that idx < extents is true, so it commits the instructions in the body of the for loop The problem is that in this scenario, the cpu read map->extent[0].first and map->nr_extents in the wrong order.

Whenever a message shows up in XenBus it is put on a xs_state.reply_list list and 'read_reply' picks it up. The problem is if the backend domain or the xenstored process is killed. In which case 'xenbus' is still awaiting - and 'read_reply' if called - stuck forever waiting for the reply_list to have some contents. This is normally not a problem - as the backend domain can come back or the xenstored process can be restarted. However if the domain is in process of being powered off/restarted/halted - there is no point of waiting on it coming back - as we are effectively being terminated and should not impede the progress. This patch solves this problem by checking whether the guest is the right domain. If it is an initial domain and hurtling towards death - there is no point of continuing the wait. All other type of guests continue with their behavior (as Xenstore is expected to still be running in another domain).

The user can launch the guest in this sequence: xl create -p /vm.cfg [launch, but pause it] xl shutdown latest [sets control/shutdown=poweroff] xl unpause latest xl console latest [and see that the guest has completely ignored the shutdown request] In reality the guest hasn't ignored it. It registers a watch and gets a notification that there is value. It then calls the shutdown_handler which ends up calling orderly_shutdown. Unfortunately that is so early in the bootup that there are no user-space. Which means that the orderly_shutdown fails. But since the force flag was set to false it continues on without reporting. What we really want to is to use the force when we are in the SYSTEM_BOOTING state and not use the 'force' when SYSTEM_RUNNING. However, if we are in the running state - and the shutdown command has been given before the user-space has been setup, there is nothing we can do. Worst yet, we stop ignoring the 'xl shutdown' requests! As such, the other part of this patch is to only stop ignoring the 'xl shutdown' when we are truly in the power off sequence. That means the user can do multiple 'xl shutdown' and we will try to act on them instead of ignoring them.

The other observation is that (on this box) we should never try the PCI reboot method, but close with either the 'triple fault' or the 'BIOS' (terminal!) reboot methods. Thirdly, CF9_COND is a total misnomer - it should be something like CF9_SAFE or CF9_CAREFUL, and 'CF9' should be 'CF9_FORCE' ... So this patch fixes the worst problems: - it orders the actual reboot logic to follow the reboot ordering pattern - it was in a pretty random order before for no good reason. - it fixes the CF9 misnomers and uses BOOT_CF9_FORCE and BOOT_CF9_SAFE flags to make the code more obvious. - it tries the BIOS reboot method before the PCI reboot method. (Since 'BIOS' is a terminal reboot method resulting in a hang if it does not work, this is essentially equivalent to removing the PCI reboot method from the default reboot chain.) - just for the miraculous possibility of terminal (resulting in hang) reboot methods of triple fault or BIOS returning without having done their job, there's an ordering between them as well.

Unfortunately it seems like a different field was dropped during review that caused this padding to become unnecessary, but the pad field wasn't removed at that time. One possible side-effect of this is that since the __u64 following the pad is now no longer properly aligned, the compiler may (or may not) introduce padding itself, which results in no predictable ABI. Rectify this by removing the pad field so that all fields are again naturally aligned. Technically this is breaking existing userspace ABI, but given that there aren't any (released) userspace drivers that make use of this yet, the fallout should be minimal.

Under a complex set of conditions, store to load forwarding for a sub 8-byte load may complete incorrectly Problem: A load instruction may complete incorrectly when a code sequence using 4-byte or smaller load and store operations to the same address is executed in combination with specific timing of all the following concurrent conditions: store to load forwarding, alignment checking enabled, a mis-predicted branch, and complex cache utilization activity. Implication: The affected sub 8-byte instruction may complete incorrectly resulting in unpredictable system behavior. There is an extremely low probability of exposure due to the significant number of complex microarchitectural concurrent conditions required to encounter the erratum. Workaround: Set PSR.ac = 0 to completely avoid the erratum. Disabling Hyper-Threading will significantly reduce exposure to the conditions that contribute to encountering the erratum. Status: See the Summary Table of Changes for the affected steppings. ========================================================================= [Table of changes essentially lists all models from McKinley to Tukwila] The PSR.ac bit controls whether the processor will always generate an unaligned reference trap (0x5a00) for a misaligned data access (when PSR.ac=1) or if it will let the access succeed when running on a cpu that implements logic to handle some unaligned accesses. Way back in 2008 in commit b704882e70d87d7f56db5ff17e2253f3fa90e4f3 [IA64] Rationalize kernel mode alignment checking we made the decision to always enable strict checking. We were already doing so in trap/interrupt context because the common preamble code set this bit - but the rest of supervisor code (and by inheritance user code) ran with PSR.ac=0. We now reverse that decision and set PSR.ac=0 everywhere in the kernel (also inherited by user processes). This will avoid the erratum using the method described in the Itanium specification update. Net effect for users is that the processor will handle unaligned access when it can (typically with a tiny performance bubble in the pipeline ... but much less invasive than taking a trap and having the OS perform the access).

Because an FLR doesn't lead to receiving any reboot even from the MC (unlike most other types of reset), we have to call efx_ef10_reset_mc_allocations. In efx_start_all(), if a reset (of any kind) is pending, we bail out. Without this, attempts to reconfigure (e.g. change mtu) can cause driver/mc state inconsistency if the first MCDI call triggers an FLR. For similar reasons, on EF10, in efx_reset_down(method=RESET_TYPE_MCDI_TIMEOUT), set the number of active queues to zero before calling efx_stop_all(). And, on farch, in efx_reset_up(method=RESET_TYPE_MCDI_TIMEOUT), set active_queues and flushes pending & outstanding to zero. efx_mcdi_mode_{poll,event}() should not take us out of fail-fast mode. Instead, this is done by efx_mcdi_reset() after the FLR completes. The new FLR reset_type RESET_TYPE_MCDI_TIMEOUT doesn't really fit into the hierarchy of reset 'scopes' whereby efx_reset() decides some resets subsume others. Thus, it uses separate logic. Also, fixed up some inconsistency around RESET_TYPE_MC_BIST, which was in the wrong place in that hierarchy. Signed-off-by: Shradha Shah Signed-off-by: David S.

A QSMII interface, as defined at http://en.wikipedia.org/wiki/Media_Independent_Interface#Quad_Serial_Gigabit_Media_Independent_Interface, is "is a method of combining four SGMII lines into a 5Gbit/s interface. QSGMII, like SGMII, uses LVDS signalling for the TX and RX data and a single LVDS clock signal. QSGMII uses significantly fewer signal lines than four SGMII busses."

However, some other platforms, namely the Armada XP GP don't use SGMII, but a QSGMII connection between the MAC and the PHY, and this case was not supported by the mvneta driver, which was relying on configuration put in place by the bootloader. While this works when the mvneta driver is built-in (because clocks are not gated), it breaks when mvneta is built as a module, because the clock is gated (all configuration is lost) and then re-enabled when the mvneta driver is loaded. In order to support all of RGMII, SGMII and QSGMII, this commit reworks how the PHY interface configuration is done, and simplifies it: it removes the mvneta_port_sgmii_config() and mvneta_gmac_rgmii_set() functions, which were strange because mvneta_gmac_rgmii_set() was called in all cases, even for SGMII configurations. Also, the mvneta_gmac_rgmii_set() function was taking a boolean as argument, which was always true. Instead, all the PHY interface configuration logic is moved into the mvneta_port_power_up() function, in a much simpler 'switch' construct, with four cases: - QSGMII: the RGMIIEn bit, the PCSEn bit in GMAC_CTRL_2 are set, and the SERDES is configured in QSGMII. Technically speaking, configuring the SERDES of the first port would be sufficient, but it is simpler to do it on all ports. - SGMII: the RGMIIEn bit, the PCSEn bit in GMAC_CTRL_2 are set, and the SERDES is configured as SGMII. - RGMII: the RGMIIEn bit in GMAC_CTRL_2 is set. The PCSEn bit is kept cleared, and no SERDES configuration is done, because RGMII is not using SERDES lanes. - other: an error is returned. For this reason, the mvneta_port_power_up() now returns an int instead of nothing, and the return value is checked by mvneta_probe(). This has been successfully tested on: * Armada XP DB, which has two RGMII and two SGMII connections * Armada XP GP, which uses QSGMII for its four interfaces * Armada 370 Mirabox, which has two RGMII connections Signed-off-by: Thomas Petazzoni Signed-off-by: David S.

Since the comedi device's main mutex is heavily used, do a down-read of its `attach_lock` rwsemaphore instead. Trying to down-read `attach_lock` should only fail if some task has down-write locked it, and that is only done while the comedi device is being attached to or detached from a low-level hardware device. Unfortunately, acquiring the `attach_lock` doesn't prevent another task replacing the comedi data buffer we are trying to mmap. The details of the buffer are held in a `struct comedi_buf_map` and pointed to by `s->async->buf_map` where `s` is the comedi subdevice whose buffer we are trying to map. The `struct comedi_buf_map` is already reference counted with a `struct kref`, so we can stop it being freed prematurely. Modify `comedi_mmap()` to call new function `comedi_buf_map_from_subdev_get()` to read the subdevice's current buffer map pointer and increment its reference instead of accessing `async->buf_map` directly. Call `comedi_buf_map_put()` to decrement the reference once the buffer map structure has been dealt with. (Note that `comedi_buf_map_put()` does nothing if passed a NULL pointer.) `comedi_buf_map_from_subdev_get()` checks the subdevice's buffer map pointer has been set and the buffer map has been initialized enough for `comedi_mmap()` to deal with it (specifically, check the `n_pages` member has been set to a non-zero value). If all is well, the buffer map's reference is incremented and a pointer to it is returned. The comedi subdevice's spin-lock is used to protect the checks. Also use the spin-lock in `__comedi_buf_alloc()` and `__comedi_buf_free()` to protect changes to the subdevice's buffer map structure pointer and the buffer map structure's `n_pages` member. (This checking of `n_pages` is a bit clunky and I [Ian Abbott] plan to deal with it in the future.)

Problem reported in Red Hat bz 1040329 for strict writes where we cache only when we hold oplock and write direct to the server when we don't. When we receive an oplock break, we first change the oplock value for the inode in cifsInodeInfo->oplock to indicate that we no longer hold the oplock before we enqueue a task to flush changes to the backing device. Once we have completed flushing the changes, we return the oplock to the server. There are 2 ways here where we can have data corruption 1) While we flush changes to the backing device as part of the oplock break, we can have processes write to the file. These writes check for the oplock, find none and attempt to write directly to the server. These direct writes made while we are flushing from cache could be overwritten by data being flushed from the cache causing data corruption. 2) While a thread runs in cifs_strict_writev, the machine could receive and process an oplock break after the thread has checked the oplock and found that it allows us to cache and before we have made changes to the cache. In that case, we end up with a dirty page in cache when we shouldn't have any. This will be flushed later and will overwrite all subsequent writes to the part of the file represented by this page. Before making any writes to the server, we need to confirm that we are not in the process of flushing data to the server and if we are, we should wait until the process is complete before we attempt the write. We should also wait for existing writes to complete before we process an oplock break request which changes oplock values. We add a version specific downgrade_oplock() operation to allow for differences in the oplock values set for the different smb versions.

The original option driver (which usb_wwan is based on) was written under the assumption that either endpoint could be missing, but evidently this cannot have been tested properly. Specifically, it would handle opening a device without bulk-in (but would blow up during resume which was implemented later), but not a missing bulk-out in write() (although it is handled in some places such as write_room()). Fortunately (?), the driver also got the test for missing endpoints wrong so the urbs were in fact always allocated, although they would be initialised using the wrong endpoint address (0) and any submission of such an urb would fail. The commit mentioned above fixed the test for missing endpoints but thereby exposed the other bugs which would now generate null-pointer exceptions rather than failed urb submissions. The regression was introduced in v3.7, but the offending commit was also marked for stable.

However, it turns out that this field gets set by usb_create_hcd(), before hcd-pci expects it, and this can result in a crash when two controllers are probed in parallel (as can happen when a new controller card is hotplugged). The companions_rwsem lock was supposed to prevent this sort of thing, but usb_create_hcd() is called outside the scope of the rwsem. A simple solution is to check that the root-hub pointer has been initialized as well as the drvdata field. This doesn't happen until usb_add_hcd() is called; that call and the check are both protected by the rwsem. This patch should be applied to stable kernels from 3.10 onward.

This avoids the problem by processing the family add/remove outside of the slave device_add call. Commit 47eba33a0997fc7362a introduced this deadlock and added a KOBJ_ADD, as the add was already reported in device_register two add events were being sent. This change suppresses the device_register add so that any slave device sysfs entries are setup before the add goes out.

When a serial port is unbound while in use, uart_close() bypasses all of this, as this is supposed to be done through uart_hangup() (invoked via tty_vhangup() in uart_remove_one_port()). However, uart_hangup() does not set the hardware's power state, leaving it powered up. This may also lead to unbounded nesting counts in clock and power management, depending on their internal implementation. Make sure to power down the port in uart_hangup(), except when the port is used as a serial console. For serial consoles, this operation must be postponed until after the port becomes completely unused. This case is not fixed yet, as it depends on a (future) fix for the tty->count vs. port->count imbalance on failed uart_open(). After this, the module clock used by the sh-sci driver is disabled on unbind while the serial port is in use.

Also, serial-omap is confused about the use of device_may_wakeup. The checks for device_may_wakeup should only be done for suspend and resume, not for pm_runtime_suspend and pm_runtime_resume. The wake-up events for PM runtime should always be enabled. The lack of pm_runtime_resume handling leads into device wake-up interrupts not working after a while for runtime PM. Rather than try to patch over the issue of adding complex tests to the pm_runtime_resume, let's fix the issues properly: 1. Make serial_omap_enable_wakeup deal with all internal PM state handling so we don't need to test for up->wakeups_enabled elsewhere. Later on once omap3 boots in device tree only mode we can also remove the up->wakeups_enabled flag and rely on the wake-up interrupt enable/disable state alone. 2. Do the device_may_wakeup checks in suspend and resume only, for runtime PM the wake-up events need to be always enabled. 3. Finally just call serial_omap_enable_wakeup and make sure we call it also in pm_runtime_resume. 4. Note that we also have to use disable_irq_nosync as serial_omap_irq calls pm_runtime_get_sync.

If -it doesn't fit in your computer, bring back the card. - - ------------------------------------------------------------------------- - - - Fixed bugs and restrictions: - - During initialization, interrupts are blindly turned on. - Having a shadow variable would cause an extra memory - access on every IO instruction. - - The interrupt (on the card) should be disabled when we - don't allocate the Linux end of the interrupt. This allows - a different driver/card to use it while all ports are not in - use..... (a la standard serial port) - == An extra _off variant of the sx_in and sx_out macros are - now available. They don't set the interrupt enable bit. - These are used during initialization. Normal operation uses - the old variant which enables the interrupt line. - - RTS/DTR issue needs to be implemented according to - specialix' spec. - I kind of like the "determinism" of the current - implementation.

The driver does - not block 115k2 on CD1864 cards. - == I called the Cirrus Logic representative here in Holland. - The CD1864 databook is identical to the CD1865 databook, - except for an extra warning at the end. Similar Bit errors - have been observed in testing at 115k2 on both an 1865 and - a 1864 chip. I see no reason why I would prohibit 115k2 on - 1864 chips and not do it on 1865 chips. Actually there is - reason to prohibit it on BOTH chips. I print a warning. - If you use 115k2, you're on your own. - - A spiky CD may send spurious HUPs. Also in CLOCAL??? - -- A fix for this turned out to be counter productive. - Different fix? Current behaviour is acceptable? - -- Maybe the current implementation is correct.

Ever misplace your Linux -kernel sources? And the manual of one of the boards in your computer? - - -Theory of operation -=================== - -An important thing to know is that the driver itself doesn't have the -firmware for the card. This means that you need the separate package -"sx_firmware". For now you can get the source at - - ftp://ftp.bitwizard.nl/specialix/sx_firmware_.tgz - -The firmware load needs a "misc" device, so you'll need to enable the -"Support for user misc device modules" in your kernel configuration. -The misc device needs to be called "/dev/specialix_sxctl". It needs -misc major 10, and minor number 167 (assigned by HPA). The section -on creating device files below also creates this device. - -After loading the sx.o module into your kernel, the driver will report -the number of cards detected, but because it doesn't have any -firmware, it will not be able to determine the number of ports. Only -when you then run "sx_firmware" will the firmware be downloaded and -the rest of the driver initialized. At that time the sx_firmware -program will report the number of ports installed. - -In contrast with many other multi port serial cards, some of the data -structures are only allocated when the card knows the number of ports -that are connected. This means we won't waste memory for 120 port -descriptor structures when you only have 8 ports. If you experience -problems due to this, please report them: I haven't seen any. - - -Interrupts -========== - -A multi port serial card, would generate a horrendous amount of -interrupts if it would interrupt the CPU for every received -character. Even more than 10 years ago, the trick not to use -interrupts but to poll the serial cards was invented. - -The SX card allow us to do this two ways. First the card limits its -own interrupt rate to a rate that won't overwhelm the CPU. Secondly, -we could forget about the cards interrupt completely and use the -internal timer for this purpose. - -Polling the card can take up to a few percent of your CPU. Using the -interrupts would be better if you have most of the ports idle. Using -timer-based polling is better if your card almost always has work to -do. You save the separate interrupt in that case. - -In any case, it doesn't really matter all that much. - -The most common problem with interrupts is that for ISA cards in a PCI -system the BIOS has to be told to configure that interrupt as "legacy -ISA". Otherwise the card can pull on the interrupt line all it wants -but the CPU won't see this. - -If you can't get the interrupt to work, remember that polling mode is -more efficient (provided you actually use the card intensively). - - -Allowed Configurations -====================== - -Some configurations are disallowed. Even though at a glance they might -seem to work, they are known to lockup the bus between the host card -and the device concentrators. You should respect the drivers decision -not to support certain configurations. It's there for a reason. - -Warning: Seriously technical stuff ahead. Executive summary: Don't use -SX cards except configured at a 64k boundary. Skip the next paragraph. - -The SX cards can theoretically be placed at a 32k boundary. So for -instance you can put an SX card at 0xc8000-0xd7fff. This is not a -"recommended configuration". ISA cards have to tell the bus controller -how they like their timing. Due to timing issues they have to do this -based on which 64k window the address falls into. This means that the -32k window below and above the SX card have to use exactly the same -timing as the SX card. That reportedly works for other SX cards. But -you're still left with two useless 32k windows that should not be used -by anybody else. - - -Configuring the driver -====================== - -PCI cards are always detected. The driver auto-probes for ISA cards at -some sensible addresses. Please report if the auto-probe causes trouble -in your system, or when a card isn't detected. - -I'm afraid I haven't implemented "kernel command line parameters" yet. -This means that if the default doesn't work for you, you shouldn't use -the compiled-into-the-kernel version of the driver. Use a module -instead. If you convince me that you need this, I'll make it for -you. Deal? - -I'm afraid that the module parameters are a bit clumsy. If you have a -better idea, please tell me. - -You can specify several parameters: - - sx_poll: number of jiffies between timer-based polls. - - Set this to "0" to disable timer based polls. - Initialization of cards without a working interrupt - will fail. - - Set this to "1" if you want a polling driver. - (on Intel: 100 polls per second). If you don't use - fast baud rates, you might consider a value like "5". - (If you don't know how to do the math, use 1). - - sx_slowpoll: Number of jiffies between timer-based polls. - Set this to "100" to poll once a second. - This should get the card out of a stall if the driver - ever misses an interrupt. I've never seen this happen, - and if it does, that's a bug. Tell me. - - sx_maxints: Number of interrupts to request from the card. - The card normally limits interrupts to about 100 per - second to offload the host CPU. You can increase this - number to reduce latency on the card a little. - Note that if you give a very high number you can overload - your CPU as well as the CPU on the host card. This setting - is inaccurate and not recommended for SI cards (But it - works). - - sx_irqmask: The mask of allowable IRQs to use. I suggest you set - this to 0 (disable IRQs all together) and use polling if - the assignment of IRQs becomes problematic. This is defined - as the sum of (1 << irq) 's that you want to allow. So - sx_irqmask of 8 (1 << 3) specifies that only irq 3 may - be used by the SX driver. If you want to specify to the - driver: "Either irq 11 or 12 is ok for you to use", then - specify (1 << 11) | (1 << 12) = 0x1800 . - - sx_debug: You can enable different sorts of debug traces with this. - At "-1" all debugging traces are active. You'll get several - times more debugging output than you'll get characters - transmitted. - - -Baud rates -========== - -Theoretically new SXDCs should be capable of more than 460k -baud. However the line drivers usually give up before that. Also the -CPU on the card may not be able to handle 8 channels going at full -blast at that speed. Moreover, the buffers are not large enough to -allow operation with 100 interrupts per second. You'll have to realize -that the card has a 256 byte buffer, so you'll have to increase the -number of interrupts per second if you have more than 256*100 bytes -per second to transmit. If you do any performance testing in this -area, I'd be glad to hear from you... - -(Psst Linux users..... I think the Linux driver is more efficient than -the driver for other OSes. If you can and want to benchmark them -against each other, be my guest, and report your findings...... :-) - - -Ports and devices -================= - -Port 0 is the top connector on the module closest to the host -card. Oh, the ports on the SXDCs and TAs are labelled from 1 to 8 -instead of from 0 to 7, as they are numbered by linux. I'm stubborn in -this: I know for sure that I wouldn't be able to calculate which port -is which anymore if I would change that.... - - -Devices: - -You should make the device files as follows: - -#!/bin/sh -# (I recommend that you cut-and-paste this into a file and run that) -cd /dev -t=0 -mknod specialix_sxctl c 10 167 -while [ $t -lt 64 ] - do - echo -n "$t " - mknod ttyX$t c 32 $t - mknod cux$t c 33 $t - t=`expr $t + 1` -done -echo "" -rm /etc/psdevtab -ps > /dev/null - - -This creates 64 devices. If you have more, increase the constant on -the line with "while". The devices start at 0, as is customary on -Linux. Specialix seems to like starting the numbering at 1. - -If your system doesn't come with these devices pre-installed, bug your -linux-vendor about this. They should have these devices -"pre-installed" before the new millennium. The "ps" stuff at the end -is to "tell" ps that the new devices exist. - -Officially the maximum number of cards per computer is 4. This driver -however supports as many cards in one machine as you want. You'll run -out of interrupts after a few, but you can switch to polled operation -then. At about 256 ports (More than 8 cards), we run out of minor -device numbers. Sorry. I suggest you buy a second computer.... (Or -switch to RIO). - ------------------------------------------------------------------------- - - - Fixed bugs and restrictions: - - Hangup processing. - -- Done. - - - the write path in generic_serial (lockup / oops). - -- Done (Ugly: not the way I want it.

If is caused by xfs_get_blocks() mapping a single extent that spans EOF without marking it as buffer-new() so that the direct IO code does not zero the tail of the block at the new EOF. This is a long standing bug that has been around for many, many years. Because xfs_get_blocks() starts the map before EOF, it can't set buffer_new(), because that causes he direct IO code to also zero unaligned sectors at the head of the IO. This would overwrite valid data with zeros, and hence we cannot validly return a single extent that spans EOF to direct IO. Fix this by detecting a mapping that spans EOF and truncate it down to EOF. This results in the the direct IO code doing the right thing for unaligned data blocks before EOF, and then returning to get another mapping for the region beyond EOF which XFS treats correctly by setting buffer_new() on it. This makes direct Io behave correctly w.r.t. tail block zeroing beyond EOF, and fsx is happy about that. Again, thanks to Al Viro for finding what I couldn't.

The key observation is that the offset of the last extent in the file was not being shifted, and hence when the file size was adjusted it was truncating away data because the extents handled been correctly shifted. Tracing indicated that before the collapse, the extent list looked like: .... ino 0x5788 state idx 6 offset 26 block 195904 count 10 flag 0 ino 0x5788 state idx 7 offset 39 block 195917 count 35 flag 0 ino 0x5788 state idx 8 offset 86 block 195964 count 32 flag 0 and after the shift of 2 blocks: ino 0x5788 state idx 6 offset 24 block 195904 count 10 flag 0 ino 0x5788 state idx 7 offset 37 block 195917 count 35 flag 0 ino 0x5788 state idx 8 offset 86 block 195964 count 32 flag 0 Note that the last extent did not change offset. After the changing of the file size: ino 0x5788 state idx 6 offset 24 block 195904 count 10 flag 0 ino 0x5788 state idx 7 offset 37 block 195917 count 35 flag 0 ino 0x5788 state idx 8 offset 86 block 195964 count 30 flag 0 You can see that the last extent had it's length truncated, indicating that we've lost data. The reason for this is that the xfs_bmap_shift_extents() loop uses XFS_IFORK_NEXTENTS() to determine how many extents are in the inode. This, unfortunately, doesn't take into account delayed allocation extents - it's a count of physically allocated extents - and hence when the file being collapsed has a delalloc extent like this one does prior to the range being collapsed: .... ino 0x5788 state idx 4 offset 11 block 4503599627239429 count 1 flag 0 .... it gets the count wrong and terminates the shift loop early. Fix it by using the in-memory extent array size that includes delayed allocation extents to determine the number of extents on the inode.

The cases reported have the same signature - the update of the superblock counters fails due to a log write IO error: XFS (dm-16): xfs_do_force_shutdown(0x2) called from line 1170 of file fs/xfs/xfs_log.c. Return address = 0xffffffffa08a44a1 XFS (dm-16): Log I/O Error Detected. Shutting down filesystem XFS (dm-16): Unable to update superblock counters. Freespace may not be correct on next mount. XFS (dm-16): xfs_log_force: error 5 returned. XFS (¿-¿¿¿): Please umount the filesystem and rectify the problem(s) It can be seen that the last line of output contains a corrupt device name - this is because the log and xfs_mount structures have already been freed by the time this message is printed. A kernel oops closely follows. The issue is that the shutdown is occurring in a separate IO completion thread to the unmount. Once the shutdown processing has started and all the iclogs are marked with XLOG_STATE_IOERROR, the log shutdown code wakes anyone waiting on a log force so they can process the shutdown error. This wakes up the unmount code that is doing a synchronous transaction to update the superblock counters. The unmount path now sees all the iclogs are marked with XLOG_STATE_IOERROR and so never waits on them again, knowing that if it does, there will not be a wakeup trigger for it and we will hang the unmount if we do. Hence the unmount runs through all the remaining code and frees all the filesystem structures while the xlog_iodone() is still processing the shutdown. When the log shutdown processing completes, xfs_do_force_shutdown() emits the "Please umount the filesystem and rectify the problem(s)" message, and xlog_iodone() then aborts all the objects attached to the iclog. An iclog that has already been freed.... The real issue here is that there is no serialisation point between the log IO and the unmount. We have serialisations points for log writes, log forces, reservations, etc, but we don't actually have any code that wakes for log IO to fully complete. We do that for all other types of object, so why not iclogbufs? Well, it turns out that we can easily do this. We've got xfs_buf handles, and that's what everyone else uses for IO serialisation. i.e. bp->b_sema. So, lets hold iclogbufs locked over IO, and only release the lock in xlog_iodone() when we are finished with the buffer. That way before we tear down the iclog, we can lock and unlock the buffer to ensure IO completion has finished completely before we tear it down.

This is done by using a "global_ops" descriptor and having the "set_ftrace_filter" and "set_ftrace_notrace" map to it. When an instance is created, it creates the same files but its for the local instance and not the global_ops. The issues is that the local instance creation shares some code with the global instance one and we end up trying to create th top level "set_ftrace_*" files twice, and on boot up, we get an error like this: Could not create debugfs 'set_ftrace_filter' entry Could not create debugfs 'set_ftrace_notrace' entry The reason they failed to be created was because they were created twice, and the second time gives this error as you can not create the same file twice.

Currently I just set - them equal to the respective synchronization values: - - - hbstrt: Start of horizontal blank - - hbstop: End of horizontal blank - - vbstrt: Start of vertical blank - - vbstop: End of vertical blank - - Horizontal values are in color clock cycles (280 ns), vertical values are in - scanlines. - - (0, 0) is somewhere in the upper-left corner :-) - - - Amiga visible window definitions - -------------------------------- - - Currently I only have values for AGA, SHRES (28 MHz dotclock). Feel free to - make corrections and/or additions. - - Within the above synchronization specifications, the visible window is - defined by the following parameters (actual register resolutions may be - different; all horizontal values are normalized with respect to the pixel - clock): - - - diwstrt_h: Horizontal start of the visible window - - diwstop_h: Horizontal stop + 1(*) of the visible window - - diwstrt_v: Vertical start of the visible window - - diwstop_v: Vertical stop of the visible window - - ddfstrt: Horizontal start of display DMA - - ddfstop: Horizontal stop of display DMA - - hscroll: Horizontal display output delay - - Sprite positioning: - - - sprstrt_h: Horizontal start - 4 of sprite - - sprstrt_v: Vertical start of sprite - - (*) Even Commodore did it wrong in the AGA monitor drivers by not adding 1. - - Horizontal values are in dotclock cycles (35 ns), vertical values are in - scanlines. - - (0, 0) is somewhere in the upper-left corner :-) - - - Dependencies (AGA, SHRES (35 ns dotclock)) - ------------------------------------------- - - Since there are much more parameters for the Amiga display than for the - frame buffer interface, there must be some dependencies among the Amiga - display parameters. Here's what I found out: - - - ddfstrt and ddfstop are best aligned to 64 pixels. - - the chipset needs 64 + 4 horizontal pixels after the DMA start before - the first pixel is output, so diwstrt_h = ddfstrt + 64 + 4 if you want - to display the first pixel on the line too. Increase diwstrt_h for - virtual screen panning. - - the display DMA always fetches 64 pixels at a time (fmode = 3). - - ddfstop is ddfstrt+#pixels - 64. - - diwstop_h = diwstrt_h + xres + 1. Because of the additional 1 this can - be 1 more than htotal. - - hscroll simply adds a delay to the display output. Smooth horizontal - panning needs an extra 64 pixels on the left to prefetch the pixels that - `fall off' on the left. - - if ddfstrt < 192, the sprite DMA cycles are all stolen by the bitplane - DMA, so it's best to make the DMA start as late as possible. - - you really don't want to make ddfstrt < 128, since this will steal DMA - cycles from the other DMA channels (audio, floppy and Chip RAM refresh). - - I make diwstop_h and diwstop_v as large as possible. - - General dependencies - -------------------- - - - all values are SHRES pixel (35ns) - - table 1:fetchstart table 2:prefetch table 3:fetchsize - ------------------ ---------------- ----------------- - Pixclock # SHRES|HIRES|LORES # SHRES|HIRES|LORES # SHRES|HIRES|LORES - -------------#------+-----+------#------+-----+------#------+-----+------ - Bus width 1x # 16 | 32 | 64 # 16 | 32 | 64 # 64 | 64 | 64 - Bus width 2x # 32 | 64 | 128 # 32 | 64 | 64 # 64 | 64 | 128 - Bus width 4x # 64 | 128 | 256 # 64 | 64 | 64 # 64 | 128 | 256 - - - chipset needs 4 pixels before the first pixel is output - - ddfstrt must be aligned to fetchstart (table 1) - - chipset needs also prefetch (table 2) to get first pixel data, so - ddfstrt = ((diwstrt_h - 4) & -fetchstart) - prefetch - - for horizontal panning decrease diwstrt_h - - the length of a fetchline must be aligned to fetchsize (table 3) - - if fetchstart is smaller than fetchsize, then ddfstrt can a little bit - moved to optimize use of dma (useful for OCS/ECS overscan displays) - - ddfstop is ddfstrt + ddfsize - fetchsize - - If C= didn't change anything for AGA, then at following positions the - dma bus is already used: - ddfstrt < 48 -> memory refresh - < 96 -> disk dma - < 160 -> audio dma - < 192 -> sprite 0 dma - < 416 -> sprite dma (32 per sprite) - - in accordance with the hardware reference manual a hardware stop is at - 192, but AGA (ECS?) can go below this. - - DMA priorities - -------------- - - Since there are limits on the earliest start value for display DMA and the - display of sprites, I use the following policy on horizontal panning and - the hardware cursor: - - - if you want to start display DMA too early, you lose the ability to - do smooth horizontal panning (xpanstep 1 -> 64). - - if you want to go even further, you lose the hardware cursor too. - - IMHO a hardware cursor is more important for X than horizontal scrolling, - so that's my motivation. - - - Implementation - -------------- - - ami_decode_var() converts the frame buffer values to the Amiga values.

This is about - 736 visible 70 ns pixels per line. - - we have 625 scanlines, of which 575 are visible (interlaced); after - rounding this becomes 576. - - RETMA -> NTSC - ------------- - - - a scanline is 63.5 µs long, of which 53.5 µs are visible. This is about - 736 visible 70 ns pixels per line. - - we have 525 scanlines, of which 485 are visible (interlaced); after - rounding this becomes 484. - - Thus if you want a PAL compatible display, you have to do the following: - - - set the FB_SYNC_BROADCAST flag to indicate that standard broadcast - timings are to be used. - - make sure upper_margin + yres + lower_margin + vsync_len = 625 for an - interlaced, 312 for a non-interlaced and 156 for a doublescanned - display. - - make sure left_margin + xres + right_margin + hsync_len = 1816 for a - SHRES, 908 for a HIRES and 454 for a LORES display. - - the left visible part begins at 360 (SHRES; HIRES:180, LORES:90), - left_margin + 2 * hsync_len must be greater or equal. - - the upper visible part begins at 48 (interlaced; non-interlaced:24, - doublescanned:12), upper_margin + 2 * vsync_len must be greater or - equal. - - ami_encode_var() calculates margins with a hsync of 5320 ns and a vsync - of 4 scanlines - - The settings for a NTSC compatible display are straightforward. - - Note that in a strict sense the PAL and NTSC standards only define the -

Arc uses a - * set of KS108 chips that control individual 64x64 LCD matrices. The board - * can be paneled in a variety of setups such as 2x1=128x64, 4x4=256x256 and - * so on. The interface between the board and the host is TTL based GPIO. The - * GPIO requirements are 8 writable data lines and 4+n lines for control. On a - * GPIO-less system, the board can be tested by connecting the respective sigs - * up to a parallel port connector. The driver requires the IO addresses for - * data and control GPIO at load time. It is unable to probe for the - * existence of the LCD so it must be told at load time whether it should - * be enabled or not. - * - * Todo: - * - testing with 4x4 - * - testing with interrupt hw - * - * General notes: - * - User must set tuhold. It's in microseconds. According to the 108 spec, - * the hold time is supposed to be at least 1 microsecond. - * - User must set num_cols=x num_rows=y, eg: x=2 means 128 - * - User must set arcfb_enable=1 to enable it - * - User must set dio_addr=0xIOADDR cio_addr=0xIOADDR - * - */ - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#include - -#define floor8(a) (a&(~0x07)) -#define floorXres(a,xres) (a&(~(xres - 1))) -#define iceil8(a) (((int)((a+7)/8))*8) -#define ceil64(a) (a|0x3F) -#define ceilXres(a,xres) (a|(xres - 1)) - -/* ks108 chipset specific defines and code */ - -#define KS_SET_DPY_START_LINE 0xC0 -#define KS_SET_PAGE_NUM 0xB8 -#define KS_SET_X 0x40 -#define KS_CEHI 0x01 -#define KS_CELO 0x00 -#define KS_SEL_CMD 0x08 -#define KS_SEL_DATA 0x00 -#define KS_DPY_ON 0x3F -#define KS_DPY_OFF 0x3E -#define KS_INTACK 0x40 -#define KS_CLRINT 0x02 - -struct arcfb_par { - unsigned long dio_addr;
