    5

    Ignore client writing state during cb completion to fix a memory
    leak.

    When moving cbs to the completion list we should not look at
    writing_state as this state can be already overwritten by next
    write, the fact that a cb is on the write waiting list means
    that it was already written to the HW and we can safely complete it.

    Same pays for wait in poll handler, we do not have to check the state
    wake is done after completion list processing.

  • 5e6533a6f   mei: me: do not load the driver if the FW doesn't support MEI interface ... Browse Code »
    5

    NM and SPS FW types that may run on ME device on server platforms
    do not have valid MEI/HECI interface and driver should not
    be bound to it as this might lead to system hung.
    In practice not all BIOSes effectively hide such devices from the
    OS and in some cases it is not possible.

    We determine FW type by examining Host FW status registers in order to
    unbind the driver.
    In this patch we are adding check for ME on Cougar Point, Lynx Point
    Devices

  • 718f762ef   GenWQE: Fix multithreading problems ... Browse Code »

    When being used in a multithreaded application there were problems
    with memory pages/cachelines accessed by multiple threads/cpus at the
    same time, while doing DMA transfers to/from those. To avoid such
    situations this fix is creating a copy of the first and the last page
    if it is not fully used. The data is copied from user-space into those
    pages and results are copied back when the DDCB-request is
    successfully finished.

    rc is not initialized, so genwqe_finish_queue() either returns -EIO or
    garbage. Fortunately the return is not being checked by any callers,
    so this has not yet caused any problems. Even so, it makes sense to
    fix this small bug in case is is checked in future.

    Pull sound updates from Takashi Iwai:
    "There have been lots of changes in ALSA core, HD-audio and ASoC, also
    most of PCI drivers touched by conversions of printks. All these
    resulted in a high volume and wide ranged patch sets in this release.
    Many changes are fairly trivial, but also lots of nice cleanups and
    refactors. There are a few new drivers, most notably, the Intel
    Haswell and Baytrail ASoC driver.

    Core changes:
    - A bit modernization; embed the device struct into snd_card struct,
    so that it may be referred from the beginning. A new
    snd_card_new() function is introduced for that, and all drivers
    have been converted.

    - Simplification in the device management code in ALSA core; now
    managed by a simple priority list instead

    - Converted many kernel messages to use the standard dev_err() & co;
    this would be the pretty visible difference, especially for
    HD-audio.

    HD-audio:
    - Conexant codecs use the auto-parser as default now; the old static
    code still remains in case of regressions. Some old quirks have
    been rewritten with the fixups for auto-parser.

    - C-Media codecs also use the auto-parser as default now, too.

    - A device struct is assigned to each HD-audio codec, and the
    formerly hwdep attributes are accessible over the codec sysfs, too.
    hwdep attributes still remain for compatibility.

    - Split the PCI-specific stuff for HD-audio controller into a
    separate module, ane make a helper module for the generic
    controller driver. This is a preliminary change for supporting
    Tegra HDMI controller in near future, which slipped from 3.15
    merge.

    - Device-specific fixes: mute LED support for Lenovo Ideapad, mic LED
    fix for HP laptops, more ASUS subwoofer quirks, yet more Dell
    laptop headset quirks

    - Make the HD-audio codec response a bit more robust

    - A few improvements on Realtek ALC282 / 283 about the pop noises

    - A couple of Intel HDMI fixes

    ASoC:
    - Lots of cleanups for enumerations; refactored lots of error prone
    original codes to use more modern APIs

    - Elimination of the ASoC level wrappers for I2C and SPI moving us
    closer to converting to regmap completely and avoiding some
    randconfig hassle

    - Provide both manually and transparently locked DAPM APIs rather
    than a mix of the two fixing some concurrency issues

    - Start converting CODEC drivers to use separate bus interface
    drivers rather than having them all in one file helping avoid
    dependency issues

    - DPCM support for Intel Haswell and Bay Trail platforms, lots of
    fixes

    - Lots of work on improvements for simple-card, DaVinci and the
    Renesas rcar drivers.

    - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of
    the CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8

    - Fixes for the simple-card DAI format DT mess

    - DT support for a couple more devices.

    - Use of the tdm_slot mapping in a few drivers

    Others:
    - Support of reset_resume callback for improved S4 in USB-audio
    driver; the device with boot quirks have been little tested, which
    we need to watch out in this development cycle

    - Add PM support for ICE1712 driver (finally!); it's still pretty
    partial support, only for M-Audio devices"

    these was error prone so he's refactored lots of code to use more
    modern APIs which avoid issues.
    - Elimination of the ASoC level wrappers for I2C and SPI moving us

  • e97ca8e5b   mm: fix GFP_THISNODE callers and clarify ... Browse Code »
    18

    GFP_THISNODE is for callers that implement their own clever fallback to
    remote nodes. It restricts the allocation to the specified node and
    does not invoke reclaim, assuming that the caller will take care of it
    when the fallback fails, e.g. through a subsequent allocation request
    without GFP_THISNODE set.

    However, many current GFP_THISNODE users only want the node exclusive
    aspect of the flag, without actually implementing their own fallback or
    triggering reclaim if necessary. This results in things like page
    migration failing prematurely even when there is easily reclaimable
    memory available, unless kswapd happens to be running already or a
    concurrent allocation attempt triggers the necessary reclaim.

    Convert all callsites that don't implement their own fallback strategy
    to __GFP_THISNODE. This restricts the allocation a single node too, but
    at the same time allows the allocator to enter the slowpath, wake
    kswapd, and invoke direct reclaim if necessary, to make the allocation
    happen when memory is full.

  • e0117521e   vmw_vmci: Use pci_enable_msix_exact() instead of pci_enable_msix() ... Browse Code »

    As result of deprecation of MSI-X/MSI enablement functions
    pci_enable_msix() and pci_enable_msi_block() all drivers
    using these two interfaces need to be updated to use the
    new pci_enable_msi_range() or pci_enable_msi_exact()
    and pci_enable_msix_range() or pci_enable_msix_exact()
    interfaces.

    While running Documentation/watchdog/src/watchdog-simple.c
    and quiting by Ctrl-C, fallowing error is displayed:
    mei_me 0000:00:16.0: wd: stop failed to complete ret=-512.

    The whatchdog core framework is not able to propagate
    -ESYSRESTART or -EINTR. Also There is no much sense in
    restarting the close system call so instead of using
    wait_event_interruptible_timeout we can use wait_event_timeout
    with reasonable 10 msecs timeout.

    1. Propagate ENOTTY to user space if the client is not present
    in the system
    2. Use ETIME consistently on timeouts
    3. Return EIO on write failures
    4. Return ENODEV on recoverable device failures such as resets

    Since txe use doorbell and not circular buffer
    we have to cheat in write slot counting, txe always consume all the
    slots upon write. In order for it to work we need to track
    slots using mei_hbuf_empty_slots() instead of tracking it in mei layer

    A client has to acquire host buffer
    before writing, we add lock like wrapper
    to replace the code snippet

    if (dev->hbuf_is_ready)
    dev->hbuf_is_ready = false;
