    ASoC: Updates for v4.8

    Not really any framework work this time around (though we have seen one
    of the Analog Devices drivers move more to the clock API which is good
    to see) but rather a lot of new drivers:

    - Lots of updates for the Intel drivers, mostly board support and bug
    fixing, and to the NAU8825 driver.
    - Work on generalizing bits of simple-card to allow more code sharing
    with the Renesas rsrc-card (which can't use simple-card due to DPCM).
    - Removal of the Odroid X2 driver due to replacement with simple-card.
    - Support for several new Mediatek platforms and associated boards.
    - New drivers for Allwinner A10, Analog Devices ADAU7002, Broadcom
    Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960 and MAX98504,
    Realtek RT5514 and Wolfson WM8758

    ASoC: Updates for v4.1

    More updates for v4.1, pretty much all drivers:

    - Lots of cleanups from Lars, mainly moving things from the CODEC level
    to the card level.
    - Continuing improvements to rcar from Morimoto-san, pcm512x from
    Howard and Peter, the Intel platforms from Vinod, Jie, Jin and Han,
    and to rt5670 from Bard.
    - Support for some non-DSP Qualcomm platforms, Google's Storm
    platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC.

  • 3088ef9f5   ALSA: ControlName.txt: Add 'Analogue' as a prefix for volume controls ... Browse Code »

    Currently 'Playback Volume' is the correct way to express an analogue
    volume control. However, this control name has initialisation defaults
    applied when using 'alsactl restore' and in some cases this is not
    appropriate. An example would be a control that has a selection of
    0db and -6dB of gain that is intended to set the fullscale ouput
    voltage of a DAC. The TI pcm512x family of DAcs have such a control.
    In this case the device/driver reset defaults are preferred.

  • 229d04309   ALSA: core: selection of audio_tstamp type and accuracy reports ... Browse Code »

    Audio timestamps can be extracted from sample counters, wall clocks,
    PHC clocks (Ethernet AVB), on-demand synchronized snapshots. This
    patch provides the ability to report timestamping capabilities, select
    timestamp types and retrieve timestamp accuracy, if supported.
    Details can be found in Documentations/sound/alsa/timestamping.txt

    This functionality is introduced by reclaiming the reserved_aligned
    field introduced by commit9c7066aef4a5eb8e4063de28f06c508bf6f2963a
    in snd_pcm_status to provide userspace with selection/query capabilities.
    Additional driver_tstamp and audio_tstamp_accuracy fields are also added.

    snd_pcm_mmap_status remains a read-only structure with only
    the audio timestamp value accessible from user space. The selection
    of audio timestamp type is done through snd_pcm_status only

    This commit does not impact ABI and does not impact the default
    behavior. By default audio timestamp is aligned with hw_pointer and
    reports the DMA position. Backwards compatibility is handled by using
    the HDAudio wall clock for playback and the hw_ptr for all other
    cases.

    For timestamp selection a new STATUS_EXT ioctl is introduced with
    read/write parameters. Alsa-lib will be modified to make use of
    STATUS_EXT.

  • 2b30d411d   ALSA: pcm: Add xrun_injection proc entry ... Browse Code »

    This patch adds a new proc entry for PCM substreams to inject an
    XRUN. When a PCM substream is running and any value is written to its
    xrun_injection proc file, the driver triggers XRUN. This is a useful
    feature for debugging XRUN and error handling code paths.

    Note that this entry is enabled only when CONFIG_SND_PCM_XRUN_DEBUG is
    set.

  • f5914908a   ALSA: pcm: Replace PCM hwptr tracking with tracepoints ... Browse Code »

    ALSA PCM core has a mechanism tracking the PCM hwptr updates for
    analyzing XRUNs. But its log is limited (up to 10) and its log output
    is a kernel message, which is hard to handle.

    In this patch, the hwptr logging is moved to the tracing
    infrastructure instead of its own. Not only the hwptr updates but
    also XRUN and hwptr errors are recorded on the trace log, so that user
    can see such events at the exact timing.

    The new "snd_pcm" entry will appear in the tracing events:
    # ls -F /sys/kernel/debug/tracing/events/snd_pcm
    enable filter hw_ptr_error/ hwptr/ xrun/

    The hwptr is for the regular hwptr update events. An event trace
    looks like:

    aplay-26187 [004] d..3 4012.834761: hwptr: pcmC0D0p/sub0: POS: pos=488, old=0, base=0, period=1024, buf=16384

    "POS" shows the hwptr update by the explicit position update call and
    "IRQ" means the hwptr update by the interrupt,
    i.e. snd_pcm_period_elapsed() call. The "pos" is the passed
    ring-buffer offset by the caller, "old" is the previous hwptr, "base"
    is the hwptr base position, "period" and "buf" are period- and
    buffer-size of the target PCM substream.
    (Note that the hwptr position displayed here isn't the ring-buffer
    offset. It increments up to the PCM position boundary.)

    The XRUN event appears similarly, but without "pos" field.
    The hwptr error events appear with the PCM identifier and its reason
    string, such as "Lost interrupt?".

    The XRUN and hwptr error reports on kernel message are still left, can
    be turned on/off via xrun_debug proc like before. But the bit 3, 4, 5
    and 6 bits of xrun_debug proc are dropped by this patch. Also, along
    with the change, the message strings have been reformatted to be a bit
    more consistent.

    Last but not least, the hwptr reporting is enabled only when
    CONFIG_SND_PCM_XRUN_DEBUG is set.

  • 8b3dfdaf0   ALSA: hda - Adjust speaker HPF and add LED support for HP Spectre 13 ... Browse Code »

    HP Spectre 13 has the IDT 92HD95 codec, and BIOS seems to set the
    default high-pass filter in some "safer" range, which results in the
    very soft tone from the built-in speakers in contrast to Windows.
    Also, the mute LED control is missing, since 92HD95 codec still has no
    HP-specific fixups for GPIO setups.

    This patch adds these missing features: the HPF is adjusted by the
    vendor-specific verb, and the LED is set up from a DMI string (but
    with the default polarity = 0 assumption due to the incomplete BIOS on
    the given machine).
