  • e4f34cf6d   Revert "ALSA: firewire-lib: change structure member with proper type" ... Browse Code »

    This reverts commit 6b7e95d1336b9eb0d4c6db190ce756480496bd13. This commit
    is based on a concern about value of the given parameter. It's expected
    to be ORed value with some enumeration-constants, thus often it can not be
    one of the enumeration-constants. I understood that this is out of
    specification and causes implementation-dependent issues.

    In C language specification, enumerated type can be interpreted as an
    integer type, in which all of enumeration-constants in corresponding
    enumerator-list can be stored. Implementations can select one of char,
    signed int and unsigned int as its type, and this selection is
    implementation-dependent.

    In GCC, a signed integer is selected when at least one of
    enumeration-constants has negative value, else an unsigned integer is
    selected. This behaviour can be switched by -fshort-enums to short type.
    Anyway, the type can be decided after scanning all of
    enumeration-constants.

    Totally, there's no rules to constrain the value of enumerated type to
    be one of enumeration-constants. In short, in enumerated type, decision
    of actual type for the type is the most important and
    enumeration-constants are just used for the decision, thus it's permitted
    to have an integer value in a range of enumeration-constants. In our case,
    actual type for the type is currently deterministic to be either char or
    unsigned int. Under GCC, it's unsigned int.

  • 13a6c8328   ALSA: usb-audio: test EP_FLAG_RUNNING at urb completion ... Browse Code »

    Testing EP_FLAG_RUNNING in snd_complete_urb() before running the completion
    logic allows us to save a few cpu cycles by returning early, skipping the
    pending urb in case the stream was stopped; the stop logic handles the urb
    and sets the completion callbacks to NULL.

  • 1d0f95308   ALSA: usb-audio: Fix irq/process data synchronization ... Browse Code »

    Commit 16200948d83 ("ALSA: usb-audio: Fix race at stopping the stream") was
    incomplete causing another more severe kernel panic, so it got reverted.
    This fixes both the original problem and its fallout kernel race/crash.

    The original fix is to move the endpoint member NULL clearing logic inside
    wait_clear_urbs() so the irq triggering the urb completion doesn't call
    retire_capture/playback_urb() after the NULL clearing and generate a panic.

    However this creates a new race between snd_usb_endpoint_start()'s call
    to wait_clear_urbs() and the irq urb completion handler which again calls
    retire_capture/playback_urb() leading to a new NULL dereference.

    We keep the EP deactivation code in snd_usb_endpoint_start() because
    removing it will break the EP reference counting (see [1] [2] for info),
    however we don't need the "can_sleep" mechanism anymore because a new
    function was introduced (snd_usb_endpoint_sync_pending_stop()) which
    synchronizes pending stops and gets called inside the pcm prepare callback.

    It also makes sense to remove can_sleep because it was also removed from
    deactivate_urbs() signature in [3] so we benefit from more simplification.

    [2] commit e9ba389c5 ("ALSA: usb-audio: Fix scheduling-while-atomic bug in PCM capture stream")

    compatible with asus-mode3 fixup, the bugzilla reporter explained that
    asus-model8 fits better for the dual headphone controls. So be it.

  • 8b0e19531   ktime: Cleanup ktime_set() usage ... Browse Code »

    ktime_set(S,N) was required for the timespec storage type and is still
    useful for situations where a Seconds and Nanoseconds part of a time value
    needs to be converted. For anything where the Seconds argument is 0, this
    is pointless and can be replaced with a simple assignment.

  • 2456e8553   ktime: Get rid of the union ... Browse Code »

    ktime is a union because the initial implementation stored the time in
    scalar nanoseconds on 64 bit machine and in a endianess optimized timespec
    variant for 32bit machines. The Y2038 cleanup removed the timespec variant
    and switched everything to scalar nanoseconds. The union remained, but
    become completely pointless.

    Get rid of the union and just keep ktime_t as simple typedef of type s64.

    The conversion was done with coccinelle and some manual mopping up.

    This reverts commit 16200948d8353fe29a473a394d7d26790deae0e7.

    The commit was intended to cover the race condition, but it introduced
    yet another regression for devices with the implicit feedback, leading
    to a kernel panic due to NULL-dereference in an irq context.

    As the race condition that was addressed by the commit is very rare
    and the regression is much worse, let's revert the commit for rc1, and
    fix the issue properly in a later patch.

    Pull sound updates from Takashi Iwai:
    "No dramatic changes are found in this development cycle, but as usual,
    many commits are applied in a wide range of drivers.

    Most of big changes are in ASoC, where a few bits of framework work
    and quite a lot of cleanups and improvements to existing code have
    been done. The rest are usual stuff, a few HD-audio and USB-audio
    quirks and fixes, as well as the drop of kthread usages in the whole
    subsystem.

    Below are some highlights:

    ASoC:
    - support for stereo DAPM controls
    - some initial work on the of-graph sound card
    - regmap conversions of the remaining AC'97 drivers
    - a new version of the topology ABI; this should be backward
    compatible
    - updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona,
    Intel skylake, atom-sst
    - new drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and
    Realtek RT5665

    USB-audio:
    - yet another race fix at disconnection
    - tolerated packet size calculation for some Android devices
    - quirks for Axe-Fx II, QuickCam, TEAC 501/503

    HD-audio:
    - improvement of Dell pin fixup mapping
    - quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic

    Misc:
    - replace all kthread usages with simple works"

  • 0a4824bf8   printk/sound: handle more message headers ... Browse Code »

    Commit 4bcc595ccd80 ("printk: reinstate KERN_CONT for printing
    continuation lines") allows to define more message headers for a single
    message. The motivation is that continuous lines might get mixed.
    Therefore it make sense to define the right log level for every piece of
    a cont line.

    This patch allows to copy only the real message level. We should ignore
    KERN_CONT because is added for each message. By other
    words, we want to know where each piece of the line comes from.

    Sampling rate changes after first set one are not reflected to the
    hardware, while driver and ALSA think the rate has been changed.

    Fix the problem by properly stopping the interface at the beginning of

    the hardware in sync with the driver.

  • 012007309   ALSA: usb-audio: Eliminate noise at the start of DSD playback. ... Browse Code »

    [Problem]
    In some USB DACs, a terrible pop noise comes to be heard
    at the start of DSD playback (in the following situations).

    - play first DSD track
    - change from PCM track to DSD track
    - change from DSD64 track to DSD128 track (and etc...)
    - seek DSD track
    - Fast-Forward/Rewind DSD track

    [Cause]
    At the start of playback, there is a little silence.
    The silence bit pattern "0x69" is required on DSD mode,
    but it is not like that.

    [Solution]
    This patch adds DSD silence pattern to the endpoint settings.
