This made some sense as there was no pin on the CPU. With Haswell came the introduction of a CPU backlight pin, but the interface was still controlled by software with the same mechnism. Behind the scenes, hardware did all the dirty work for us. Broadwell no longer provides this for free. If we want to use the PCH backlight pin [1] then we have to set the override bit BLC_PWM_PCH_CTL1 and program BLC_PWM_PCH_CTL2 for the PWM values. This patch implements that. This patch is compile tested only, and given that I rarely if ever touch this code, careful review is welcome. [1] According to Art, we know of no devices that exist which use the CPU pin (and remember it has existed already on HSW). If such a device does exist, we'll have to handle it properly - this is left as TODO until then. v2: Drop the abstraction prep patch, as a bigger backlight overhaul is in the works, and do just the mimimal bdw enabling now.

For both Suspend and Disconnect events there is one interrupt USBSusp, but calling s3c_hsotg_disconnect from this interrupt handler causes config reset in composite layer, which is not undesirable for Suspended state. For this reason s3c_hsotg_disconnect is called from SET_ADDRESS request handler, which occurs always after disconnection, so we do disconnect immediately before we are connected again.

This induces a bug for gadget only USB device controllers where the kernel tries to use Host Negotiation Protocol with such controllers, which causes a panic.

The current generic write implementation introduced by commit 27c7acf22047 ("USB: serial: reimplement generic fifo-based writes") has always had this bug, although it's fairly hard to trigger and the consequences are not likely to be noticed. Specifically, a write() on one CPU while the completion handler is running on another could result in only one of the two write urbs being utilised to empty the remainder of the write fifo (unless there is a second write() that doesn't race during that time).

One loop means a udelay(1). The delay seems to depend on the packet size. On HS the bit is always cleared for small packet sizes while on FS it is never the case, it mostly around 110us. This testing has been performed with g_ether (musb as device) and using BULK transfers. INTR transfers are way more fun: during init the gadget sends a INT packet to the host and cppi41 says "transfer done" shortly after. The MUSB_TXCSR_TXPKTRDY bit is set even seconds later. The reason is that the host did not try to receive it, it does so after the interface (on host side) has been configured. Until this happens, that packet remains in musb's FIFO. To fix this, two things are done: - No DMA transfers for INT based endpoints. These transfer are usually very small and rare so it is likely better to skip the DMA engine and stuff the four bytes directly into the FIFO - on HS we poll up to 25us and hope that bit goes away. If not we setup a hrtimer to poll for it. The 140us delay is a rule of thumb. In FS the command | ping 10.10.10.10 -c1 -s65130 creates about 44 1514bytes transfers. About 19 of them need a second timer to complete.

Since calibrations are notification from firmware and not Rx packets, this doesn't change anyway - the firmware will fire an interrupt straight away regardless of the interrupt coalescing value. Also, a HW issue has been discovered in 7000 devices series. The work around is to disable the new interrupt coalescing timeout feature - do this by setting bit 31 in CSR_INT_COALESCING. This has been fixed in 7265 which means that we can't rely on the device family and must have a hint in the iwl_cfg structure.

Some investigation documented in kernel bug #65281 led me to the conclusion that the source of the problem is the device_del() in pci_stop_dev() as it now causes the sysfs directory of the device to be removed recursively along with all of its subdirectories. That includes the sysfs directory of the device's subordinate bus (dev->subordinate) and its "power" group. Consequently, when pci_remove_bus() is called for dev->subordinate in pci_remove_bus_device(), it calls device_unregister(&bus->dev), but at this point the sysfs directory of bus->dev doesn't exist any more and its "power" group doesn't exist either. Thus, when dpm_sysfs_remove() called from device_del() tries to remove that group, it triggers the above warning. That indicates a logical mistake in the design of pci_stop_and_remove_bus_device(), which causes bus device objects to be left behind their parents (bridge device objects) and can be fixed by moving the device_del() from pci_stop_dev() into pci_destroy_dev(), so pci_remove_bus() can be called for the device's subordinate bus before the device itself is unregistered from the hierarchy. Still, the driver, if any, should be detached from the device in pci_stop_dev(), so use device_release_driver() directly from there.

One such example is the possibility of the context switch causing an eviction or hitting the shrinker in order to fit its object into the aperture.

That leads to a deadlock. It does not happen often in practice because all callers of release_filter() stop filtering by themselves. So the problem can happen in case of race condition only. The patch releases dvbdmx->mutex before call to feed->stop_filtering(feed) and reacquires the mutex after that. Found by Linux Driver Verification project (linuxtesting.org).

However, the shrinker can and will reap any object that is unbound if the allocation for the array first fails. This includes the object which we are attempting to vmap(). The solution is to mark the object's pages as pinned whilst we try the allocation to prevent the use-after-free introduced by the potential shrinkage.

For devices supporting multiple report or diagnostic packets, the USB transfer size is now limited to the USB endpoints wMaxPacketSize - otherwise it defaults to the configured report packet size as before. This fixes an issue where event reporting can be delayed for an arbitrary time for multi packet devices. For instance the report size for eGalax devices is defined to the 16 byte maximum diagnostic packet size as opposed to the 5 byte report packet size. In case the driver requests 16 byte from the USB interrupt endpoint, the USB host controller driver needs to split up the request into 2 accesses according to the endpoints wMaxPacketSize of 8 byte. When the first transfer is answered by the eGalax device with not less than the full 8 byte requested, the host controller has got no way of knowing whether the touch controller has got additional data queued and will issue the second transfer. If per example a liftoff event finishes at such a wMaxPacketSize boundary, the data will not be available to the usbtouch driver until a further event is triggered and transfered to the host. From user perspective the BTN_TOUCH release event in this case is stuck until the next touch down event.

This patch resolves a dead lock issue that could be incurred when exynos_drm_crtc_dpms function was called. The exynos_drm_crtc_dpms function waits for the completion of pended page flip events. However, preclose callback - this releases all unhandled page flip events - is called prior to the exynos_drm_crtc_dpms function call when drm is closed. So at this time, this will make the exynos_drm_crtc_dpms to wait infiniately for the completion of the page flip events. This patch releases the unhandled page flip events at postclose instead of preclose so that exynos_drm_crtc_dpms function can be waked up. Changelog v2: - fix a memory leak when drm is closed. . it has a memory leak when a requeste page flip is handled after drm_events_release() is called and before drm_fb_release() is called. At this time, a drm_pending_event will not be freed. So also this chage releases the drm_pending_event at postclose(). And it calls drm_vblank_put() for pair if there is any unhandled page flip event.

If this isn't done the USB frames aren't formatted correctly and, for example, the USB3 ethernet ax88179_178a card will stop sending (while still receiving) when running a netperf tcp transmit test with (say) and 8k buffer. This should be a candidate for stable, the ax88179_178a driver defaults to gso and tso enabled so it passes a lot of fragmented skb to the USB stack. Notes from Sarah: Discussion: http://marc.info/?l=linux-usb&m=138384509604981&w=2 This patch fixes a long-standing xHCI driver bug that was revealed by a change in 3.12 in the usb-net driver. Commit 638c5115a794981441246fa8fa5d95c1875af5ba "USBNET: support DMA SG" added support to use bulk endpoint scatter-gather (urb->sg). Only the USB ethernet drivers trigger this bug, because the mass storage driver sends sg list entries in page-sized chunks. This patch only fixes the issue for bulk endpoint scatter-gather. The problem will still occur for periodic endpoints, because hosts will interpret no-op transfers as a request to skip a service interval, which is not what we want. Luckily, the USB core isn't set up for scatter-gather on isochronous endpoints, and no USB drivers use scatter-gather for interrupt endpoints. Document this known limitation so that developers won't try to use urb->sg for interrupt endpoints until this issue is fixed. The more comprehensive fix would be to allow link TRBs in the middle of the endpoint ring and revert this patch, but that fix would touch too much code to be allowed in for stable. This patch should be backported to kernels as old as 3.12, that contain the commit 638c5115a794981441246fa8fa5d95c1875af5ba "USBNET: support DMA SG". Without this patch, the USB network device gets wedged, and stops sending packets.

Introduce a special PCI helper function pci_device_is_present() for this purpose. Of course, this uncovers the lack of the appropriate RTNL locking in tg3_suspend() and tg3_resume(), so add that locking in there too.

So we add logical minimum to the selector values before setting those fields. Some sensor hub FWs already changed logical minimum from 0 to 1 to reflect this and hope every other vendor will follow.

This works because we don't overwrite any memory after the data buffer, we remove it from cache if it was there. So we hurt performace in case the mapping of a smaller area makes a difference. There is also a bug: If the data area starts shortly before the end of RAM say 0xc7fffa10 and the RAM ends at 0xc8000000 then we have enough space to fit the data area (according to skb->len) but we would map beyond end of ram if we are using 2048. In v2.6.31 (against which kernel this patch made) there is the following check in dma_cache_maint(): |BUG_ON(!virt_addr_valid(start) || !virt_addr_valid(start + size - 1)); Since the area starting at 0xc8000000 is no longer virt_addr_valid() we BUG() during dma_map_single(). The BUG() statement was removed in v3.5-rc1 as per 2dc6a016 ("ARM: dma-mapping: use asm-generic/dma-mapping-common.h"). This patch was tested on v2.6.31 and then forward-ported and compile tested only against the net tree. I think it is still worth fixing mainline even after the BUG() statement is gone.

This fixes a problem where unauthenticated devices that lose their connection before they are authenticated will stay in the device tree forever. More importantly, devices in this situation will never relinquish their port on the root hub so eventually all root ports will be taken up and no other devices can connect. A comment in the existing code states that there are some devices that may not respond to keepalives if they have not been authenticated. That comment is about 5 years old and I don't know of any WUSB devices that act that way. Either way, any buggy devices that may still be around will continue to work as long as they can transition to the authenticated state within the WUSB LOA timeout of 4s, which is not unreasonable to expect.

Until now the ftdi_sio driver would only report this limitation for CS6 to dmesg and fail to reflect this fact to tcgetattr. This patch reverts the unsupported CSIZE setting and reports the fact with less severance to dmesg for both CS5 and CS6. To test the patch it's sufficient to call stty -F /dev/ttyUSB0 cs5 which will succeed without the patch and report an error with the patch applied. As an additional fix this patch ensures that the control request will always include a data bit size.

The task thread is stopped in xenvif_disconnect() but task is not set to NULL. Thus, on a re-connect the check will give a false positive. Also since commit ea732dff5cfa10789007bf4a5b935388a0bb2a8f (Handle backend state transitions in a more robust way) it should not be possible for xenvif_connect() to be called if the vif is already connected so change the check of vif->tx_irq to a BUG_ON() and also add a BUG_ON(vif->task).

During initialisation of the driver, it is imperative that we reset the config state. This correctly sets up the initial connector statuses and prepares the hardware for a thorough probing. However, during a lid event, we only want to undo the damage caused by the bios by resetting our last known mode. In this cirumstance, we do not want to clobber our desired state. In order to try and keep sanity between the config state and our own tracking, do the drm_mode_config_reset() first along the load/resume paths before reading out the hw state and apply any definite known corrections. v2: "As discussed on irc I don't think we should force the connector state to anything here: Imo connector->status should reflect what we believe to be the true output connection state, whereas connector->encoder reflects whether this connector is wired up to a pipe. And since we no longer reject modeset on disconnected connectors and never nuked the pipe if the connector gets disconnected there's no reason for that - such policy is userspace's job.

The accounting was broken in a couple of ways: 1) We did not differentiate between user dma buffers and kernel dma buffers. 2) The ttm_bo_acc_size function is broken in that it a) Doesn't take into account the size of the optional dma address array, b) Doesn't take into account the fact that drivers typically embed the ttm_tt structure. This needs to be fixed in ttm, but meanwhile provide a vmwgfx-specific function to do the job.

(It transpires that Windows seems to send IPv6 packets with a fragment header even if they are not a fragment - i.e. offset is zero, and M bit is not set). This patch also incorporates a fix to callers of maybe_pull_tail() where skb->network_header was being erroneously added to the length argument.

For am3517 this is needed for passing the interrupt_enable and interrupt_disable callbacks that access the omap system control module registers. These callback functions will eventually go away when we have a separate system control module driver. Some of the things that are currently passed as platform data we don't need to set up as device tree properties as they are always the same on am3517. So let's use a new compatible flag for those so we can get those from the device tree match data. Also note that we need to fix setting of phy_dev to NULL instead of an empty string as the code later on uses that to find the first phy on the mdio bus.

With list debugging enabled that usually results in us chasing a poisoned pointer - which means we've hit upon a vma that has been removed from all lrus with list_del (and then deallocated, so it's a real use-after free). Ian Lister has done some great callchain chasing and noticed that we can reenter do_switch: i915_gem_do_execbuffer() i915_switch_context() do_switch() from = ring->last_context; i915_gem_object_pin() i915_gem_object_bind_to_gtt() ret = drm_mm_insert_node_in_range_generic(); // If the above call fails then it will try i915_gem_evict_something() // If that fails it will call i915_gem_evict_everything() ... i915_gem_evict_everything() i915_gpu_idle() i915_switch_context(DEFAULT_CONTEXT) Like with everything else where the shrinker or eviction code can invalidate pointers we need to reload relevant state. Note that there's no need to recheck whether a context switch is still required because: - Doing a switch to the same context is harmless (besides wasting a bit of energy). - This can only happen with the default context. But since that one's pinned we'll never call down into evict_everything under normal circumstances. Note that there's a little driver bringup fun involved namely that we could recourse into do_switch for the initial switch. Atm we're fine since we assign the context pointer only after the call to do_switch at driver load or resume time. And in the gpu reset case we skip the entire setup sequence (which might be a bug on its own, but definitely not this one here). Cc'ing stable since apparently ChromeOS guys are seeing this in the wild (and not just on artificial stress tests), see the reference. Note that in upstream code doesn't calle evict_everything directly from evict_something, that's an extension in this product branch. But we can still hit upon this bug (and apparently we do, see the linked backtraces). I've noticed this while trying to construct a testcase for this bug and utterly failed to provoke it. It looks like we need to driver the system squarly into the lowmem wall and provoke the shrinker to evict the context object by doing the last-ditch evict_everything call. Aside: There's currently no means to get a badly-fragmenting hw context object away from a bad spot in the upstream code. We should fix this by at least adding some code to evict_something to handle hw contexts.

This presents us with a problem, since our page tables are protected with a spinlock. This patch reworks the smmu_domain lock to use a mutex instead of a spinlock. iova_to_phys is then reworked so that it only reads the page tables, and can run in a lockless fashion, leaving the mutex to guard against concurrent mapping threads.

Now many devices has in-built sensor hubs. So by default this HID hub, is properly parsed and register individual sensors as platform device using MFD framework. But if a second sensor hub is attached via USB, which has same sensors, it will result in kernel warning and failure to register MFD cell as the platform device sysfs file name will be same as created by in-built sensor hubs. This patch sets MFD cell id to PLATFORM_DEVID_AUTO. In this way there will never be duplicate sysfs file names.

Commit dc77523c5da5513df1bbc74db2a522a94f4cec0e ensured that m.offset is only set for the MMAP memory mode by calling __setup_offsets only for that mode. However, __setup_offsets also initializes the length fields, and that should be done regardless of the memory mode. Because of that change the v4l2-ctl test application fails for the USERPTR mode. This fix creates a __setup_lengths function that sets the length, and __setup_offsets just sets the offset and no longer touches the length.

It turned out that the fix for one side triggers another BIOS bug in other side. So, it's exclusive. Since the original S5 wakeups have been confirmed only on HP machines, it'd be safer to apply it only to limited machines. As a wild guess, limiting to machines with HP PCI SSID should suffice.

The reason for space leaking is that chunks in the snapshot device are allocated sequentially, but they are finished (and stored in the metadata) out of order, depending on the order in which copying finished. For example, supposed that the metadata contains the following records SUPERBLOCK METADATA (blocks 0 ... 250) DATA 0 DATA 1 DATA 2 ... DATA 250 Now suppose that you allocate 10 new data blocks 251-260. Suppose that copying of these blocks finish out of order (block 260 finished first and the block 251 finished last). Now, the snapshot device looks like this: SUPERBLOCK METADATA (blocks 0 ... 250, 260, 259, 258, 257, 256) DATA 0 DATA 1 DATA 2 ... DATA 250 DATA 251 DATA 252 DATA 253 DATA 254 DATA 255 METADATA (blocks 255, 254, 253, 252, 251) DATA 256 DATA 257 DATA 258 DATA 259 DATA 260 Now, if the machine crashes after writing the first metadata block but before writing the second metadata block, the space for areas DATA 250-255 is leaked, it contains no valid data and it will never be used in the future. This patch makes dm-snapshot complete exceptions in the same order they were allocated, thus fixing this bug. Note: when backporting this patch to the stable kernel, change the version field in the following way: * if version in the stable kernel is {1, 11, 1}, change it to {1, 12, 0} * if version in the stable kernel is {1, 10, 0} or {1, 10, 1}, change it to {1, 10, 2} Userspace reads the version to determine if the bug was fixed, so the version change is needed.

Fix this by not updating the stats during map() if -EWOULDBLOCK will be returned. The mq policy will only update stats, consider migration, etc, once per tick period (a unit of time established between dm-cache core and the policies). When the IO thread calls the policy's map method, if it would like to migrate the associated block it returns -EWOULDBLOCK, the IO then gets handed over to a worker thread which handles the migration. The worker thread calls map again, to check the migration is still needed (avoids a race among other things). *BUT*, before this fix, if we were still in the same tick period the stats were already updated by the previous map call -- so the migration would no longer be requested.

And it can't really since that requires us to grab a mutex. Instead of jumping through hoops and offloading this to a worker thread just block this bit of code for the modesetting driver. Note that the race is fairly easy to hit since we call the breadcrumb function for any interrupt. So the vblank interrupt (which usually keeps going for a bit) is enough. But even if we'd block this and only update the breadcrumb for user interrupts from the CS we could hit this race with kms/gem userspace: If a non-master is waiting somewhere (and hence has interrupts enabled) and the master closes its fd (probably due to crashing). v2: Add a code comment to explain why fixing this for real isn't really worth it. Also improve the commit message a bit. v3: Fix the spelling in the comment.

The checksum setup code in netback was only doing that pullup in the case when the pseudo header checksum was being recalculated though. This patch makes that pullup unconditional. (I pullup the whole transport header just for simplicity; the requirement is only for the check field but in the case of UDP this is the last field in the header and in the case of TCP it's the last but one). The lack of pullup manifested as failures running Microsoft HCK network tests on a pair of Windows 8 VMs and it has been verified that this patch fixes the problem.

Thus, writing 1 to the corresponding bits in INTCLR cannot clear the corresponding bits in the INTDT register. Instead, when an external input signal is stopped, the corresponding bit in INTDT is cleared automatically. Since the INTDT bit cannot be cleared for the level interrupts until the interrupt signal is stopped, we end up with the infinite loop when using deferred (threaded) IRQ handling. Since a deferred interrupt is disabled by the low-level handler and re-enabled only when the deferred handler is completed, Fix the issue by dropping disabled interrupts from the pending mask as suggested by Laurent Pinchart Changes in V2: * Drop disabled interrupts from pending mask altogether instead of dropping level interrupts one by one once they get handled.

The wrong shift is applied to the bit - the raw skb gso type is used rather then the translated one. This leads to large packets being handed to the guest without the GSO metadata. This patch fixes the check. The mistake manifested as errors whilst running Microsoft HCK large packet offload tests between a pair of Windows 8 VMs. I have verified this patch fixes those errors.

Fix this by using dmaengine_unmap_data in the self-test routines. In addition, since dmaengine_unmap() assumes that all mappings were created with dma_map_page, this commit changes the single mapping to a page mapping to avoid an incorrect unmapping of the memcpy self-test. The allocation could be changed to be alloc_page(), but sticking to kmalloc results in a less intrusive patch. The size of the test buffer is increased, since dma_map_page() seem to fail when the source and destination pages are the same page.

Unfortunately, there are paths which end up storing an error pointer in this array, which we then try and dereference in the cleanup code, which causes an oops. Fix this by avoiding writing invalid pointers to this array in the first place.

However the code in increase_reservation does modify the p2m for auto_translate guests, but not in decrease_reservation. Fix that by avoiding any p2m modifications in both increase_reservation and decrease_reservation for auto_translated guests. And also avoid allocating or using scratch pages for auto_translated guests. Lastly, since !auto-xlat is really another way of saying 'xen_pv' remove the redundant 'xen_pv_domain' check.

To fix this regression we return an error code from the mutator function pointer passed to sm_ll_mutate() and have dec_ref_count() return -EINVAL if the old ref_count is 0. Add a DMERR to reflect the potential seriousness of this error. Also, add missing dm_tm_unlock() to sm_ll_mutate()'s error path. With this fix the following dmts regression test now passes: dmtest run --suite cache -n /metadata_use_kernel/ The next patch fixes the higher-level dm-array code that exposed this regression.

It added a check that the LCR was written properly to detect and workaround the busy quirk, but the behaviour of bit 5 (UART_LCR_SPAR) differs between IP versions 3.00a and 3.14c per the docs. On older versions this caused the check to fail and it would repeatedly force idle and rewrite the LCR register, causing delays and preventing any input from serial being received. This is fixed by masking out UART_LCR_SPAR before making the comparison.

This meant they had to put their hardware registers in the PCI BAR 2 region instead of PCI BAR 1. Unfortunately, they kept the same PCI device ID for the new design. This means the driver recognizes the newer cards, but doesn't work (and is likely to screw up the local configuration registers of the PLX chip) because it's using the wrong region. Since the PCI subvendor and subdevice IDs were both zero on the old design, but are the same as the vendor and device on the new design, we can tell the old design and new design apart easily enough.

Option 2 adds checks for behavior that is already documented as broken when using get_user_pages().

This patch moves the np->np_thread NULL assignment into iscsit_del_np(), after kthread_stop() has completed. It also removes the signal_pending() + np_state check, and only exits when kthread_should_stop() is true.
