    "As shown in diffstat and logs, it was again a busy development cycle
    at this time, too. The most significant changes are still on-going
    refactoring / modernization works for ASoC core and drivers, but there
    are lots of other changes as well. Here we go, some highlights below:

    ASoC:

    - Quite a lot of cleanup / refactoring of ASoC core and APIs; most of
    them are systematic, but also including cleanups and modernization

    - A bulk of updates for some ASoC platforms, Freescale, sunxi and
    Intel SST/SOF

    - Initial support for Sound Open Firmware on i.MX8

    - Removal of deprecated w90x900 and nuc900 drivers

    - New support for Cirrus Logic CS47L15 and CS47L92, Freescale i.MX
    7ULP and 8MQ, Meson G12A and NXP UDA1334

    USB-audio:

    - More validations of descriptor units for hardening against bugs
    reported by fuzzers

    - PCM device assignment workaround for a past call-order change

    - Scarlett Gen2 mixer interface, a few more more quirks

    HD-audio:

    - Support for audio component with AMD/ATI and Nvidia HDMI codecs

    - Clean up HD-audio core and remove indirect access ops for Intel SOF

    - DMIC detection at probe; it would make systems automatically
    falling back to SST/SOF driver on devices that need DMIC handling.
    Needs a new Kconfig to set, and beware that it's still new and a
    bit experimental

    FireWire:

    - Lots of code refactoring and cleanups"

    ASoC: Updates for v5.4

    Quite a big update this time around, particularly in the core
    where we've had a lot of cleanups from Morimoto-san - there's
    not much functional change but quite a bit of modernization
    going on. We've also seen a lot of driver work, a lot of it
    cleanups but also some particular drivers.

    - Lots and lots of cleanups from Morimoto-san and Yue Haibing.
    - Lots of cleanups and enhancements to the Freescale, sunxi dnd
    Intel rivers.
    - Initial Sound Open Firmware suppot for i.MX8.
    - Removal of w90x900 and nuc900 drivers as the platforms are
    being removed.
    - New support for Cirrus Logic CS47L15 and CS47L92, Freescale
    i.MX 7ULP and 8MQ, Meson G12A and NXP UDA1334

  • a2ef03fe6   ALSA: hda - Add a quirk model for fixing Huawei Matebook X right speaker ... Browse Code »

    [ This is rather a revival of the patch Tomas sent in months ago, but
    applying only with the quirk model option -- tiwai ]

    Hard coded coefficients to make Huawuei Matebook X right speaker
    work. The Matebook X has a ALC298, please refer to bug 197801 on
    how these numbers were reverse engineered from the Windows driver

    The reversed engineered sequence represents a repeating pattern
    of verbs, and the only values that are changing periodically are
    written on indexes 0x23 and 0x25:

    0x500, 0x23
    0x400, VALUE1
    0x500, 0x25
    0x400, VALUE2

    * skipped reading sequences (0x500 - 0xc00 sequences are ignored)
    * static values from reverse engineering are used

    NOTE: since a significant risk is still considered, this is provided
    as an experimental fix that isn't applied as default for now. For
    enabling the fix, you'll have to choose huawei-mbx-stereo via model
    option of snd-hda-intel module.

    If we get feedback from users that this works stably, we may apply it
    per default.

    [ Some coding style fixes and replacement with AC_VERB_* by tiwai ]

    ASoC: More changes for v5.1

    Another batch of changes for ASoC, no big core changes - it's mainly
    small fixes and improvements for individual drivers.

    - A big refresh and cleanup of the Samsung drivers, fixing a number of
    issues which allow the driver to be used with a wider range of
    userspaces.
    - Fixes for the Intel drivers to make them more standard so less likely
    to get bitten by core issues.
    - New driver for Cirrus Logic CS35L26.

    We used to pass NULL to memory allocators for ISA devices due to
    historical reasons. But we prefer rather a proper device object to be
    assigned, so let's fix it by replacing snd_dma_isa_data() call with
    card->dev reference, and kill snd_dma_isa_data() definition.

    | Can we just admit that we work with computers, and we don't need to

    dictionary.com refers to the word as "Chiefly British", which is

    ASoC: Updates for v4.19

    A fairly big update, including quite a bit of core activity this time
    around (which is good to see) along with a fairly large set of new
    drivers.

    - A new snd_pcm_stop_xrun() helper which is now used in several
    drivers.
    - Support for providing name prefixes to generic component nodes.
    - Quite a few fixes for DPCM as it gains a bit wider use and more
    robust testing.
    - Generalization of the DIO2125 support to a simple amplifier driver.
    - Accessory detection support for the audio graph card.
    - DT support for PXA AC'97 devices.
    - Quirks for a number of new x86 systems.
    - Support for AM Logic Meson, Everest ES7154, Intel systems with
    RT5682, Qualcomm QDSP6 and WCD9335, Realtek RT5682 and TI TAS5707.

    ASoC: Updates for v4.18

    This is a very big update, mainly due to a huge set of new drivers some
    of which are individually very large. We also have a lot of fixes for
    the topology stuff, several of the users have stepped up and fixed some
    the serious issues there, and continued progress on the transition away
    from CODEC specific drivers to generic component drivers.

    - Many fixes for the topology code, including fixes for the half done
    v4 ABI compatibility from Guenter Roeck and other ABI fixes from
    Kirill Marinushkin.
    - Lots of cleanup for Intel platforms based on Realtek CODECs from Hans
    de Goode.
    - More followups on removing legacy CODEC things and transitioning to
    components from Morimoto-san.
    - Conversion of OMAP DMA to the new, more standard SDMA-PCM driver.
    - A series of fixes and updates to the rather elderly Cirrus Logic SoC
    drivers from Alexander Sverdlin.
    - Qualcomm DSP support from Srinivas Kandagatla.
    - New drivers for Analog SSM2305, Atmel I2S controllers, Mediatek

  • f274baa49   ALSA: usb-audio: Allow non-vmalloc buffer for PCM buffers ... Browse Code »

    Currently, USB-audio driver allocates the PCM buffer via vmalloc(), as
    this serves merely as an intermediate buffer that is copied to each
    URB transfer buffer. This works well in general on x86, but on some
    archs this may result in cache coherency issues when mmap is used.
    OTOH, it works also on such arch unless mmap is used.

    This patch is a step for mitigating the inconvenience; a new module
    option "use_vmalloc" is provided so that user can choose to allocate
    the DMA coherent buffer instead of the existing vmalloc buffer.
    The drawback is that it'd be the standard dma_alloc_coherent() calls
    and the system would require contiguous pages on non-x86 archs.

    Note that it's a global option and not dynamically switchable since
    the buffer is pre-allocated at the probe time. In theory, it's
    possible to be switchable, but it'd be trickier and racier.

    As default use_vmalloc option is set to true, so that the old behavior
    is kept. For allowing the coherent mmap on ARM or MIPS, pass
    use_vmalloc=0 option explicitly.

    Pull sound updates from Takashi Iwai:
    "There are no big surprising changes in this cycle, yet not too boring,
    either. The biggest change from diffstat POV is the removal of the
    legacy OSS driver codes that have been already disabled for a long
    time. This will bring a few trivial merge conflicts.

    As new features in ASoC side, there are two things: a new AC97 bus
    implementation and AMD Stony platform support. Both include the
    relevant changes shared with other subsystems, e.g. AC97 MFD changes
    and DRM AMD changes.

    Some other highlighted topics are:

    - A bunch of USB-audio drivers got the hardening against the
    malicious device accesses with a new helper code for endpoint
    sanity check

    - Lots of cleanups for ASoC Intel platform code, including support
    for their open source audio firmware

    - Continued ASoC core componentization works

    - Support for scaling MCLK with sample rate in ASoC simple-card

    - Stabler PCM hot-unplug capability, especially for ASoC usages"

  • 727dede0b   sound: Retire OSS ... Browse Code »

    Since no complaints have been raised after disabling the build of OSS
    (Open Sound System) by the commit 31cbee6a5611 ("sound: Disable the
    build of OSS drivers"), let's finally drop the whole code and
    documentation.

    Some glue codes are still left intact since sound/oss/dmasound stuff
    remains -- which is an independent implementation solely for m68k, and
    it's not covered by ALSA yet.

    Also, a couple of API header files (linux/sound.h and
    linux/soundcard.h) are kept remaining as well, since the OSS API
    itself is still supported by ALSA OSS emulation, and applications can
    refer to these.

    Where we're at it, some help texts in the top-level Kconfig are
    adjusted, too (who still needs to specify I/O port in kbuild
    nowadays?).
