  • ab69a4904   ALSA: pcm: support for period wakeup disabling ... Browse Code »

    This patch allows to disable period interrupts which are
    not needed when the application relies on a system timer
    to wake-up and refill the ring buffer. The behavior of
    the driver is left unchanged, and interrupts are only
    disabled if the application requests this configuration.
    The behavior in case of underruns is slightly different,
    instead of being detected during the period interrupts the
    underruns are detected when the application calls
    snd_pcm_update_avail, which in turns forces a refresh of the
    hw pointer and shows the buffer is empty.

    More specifically this patch makes a lot of sense when
    PulseAudio relies on timer-based scheduling to access audio
    devices such as HDAudio or Intel SST. Disabling interrupts
    removes two unwanted wake-ups due to period elapsed events
    in low-power playback modes. It also simplifies PulseAudio
    voice modules used for speech calls.

    To quote Lennart "This patch looks very interesting and
    desirable. This is something have long been waiting for."

    Support for this in hardware drivers is optional.

  • 15c0cee6c   ALSA: pcm: Define G723 3-bit and 5-bit formats ... Browse Code »

    This defines the 24bps and 40bps (8khz sample rate) G.723 codec
    formats. They are going to be used once I submit the driver for
    an mpeg4/g723 compression card.

    I've updated the signed value to -1 as per Takashi's comments
    since these are non-linear formats.

  • 8bea869c5   ALSA: PCM midlevel: improve fifo_size handling ... Browse Code »

    Move the fifo_size assignment to hw->ioctl callback to allow lowlevel
    drivers overwrite the default behaviour.

    fifo_size is in frames not bytes as specified in asound.h and alsa-lib's
    documentation, but most hardware have fixed byte based FIFOs. Introduce
    internal SNDRV_PCM_INFO_FIFO_IN_FRAMES.

    This takes care of all files that have only a small number
    of non-strict integer type uses.

  • 85efde6f4   make exported headers use strict posix types ... Browse Code »

    A number of standard posix types are used in exported headers, which
    is not allowed if __STRICT_KERNEL_NAMES is defined. In order to
    get rid of the non-__STRICT_KERNEL_NAMES part and to make sane headers
    the default, we have to change them all to safe types.

    There are also still some leftovers in reiserfs_fs.h, elfcore.h
    and coda.h, but these files have not compiled in user space for
    a long time.

    This leaves out the various integer types ({u_,u,}int{8,16,32,64}_t),
    which we take care of separately.

  • ff33f2303   ALSA: Increase components array size ... Browse Code »

    Increase the card components[] (and thus snd_card_info.components[],
    too) array size from 80 to 128 chars so that more strings can be
    stored. The 80 chars aren't enough for more than 2 HD-audio codecs,
    and this hits an ugly snd_BUG() as reported by Wu Fegguang for HP
    2230s.

    The control protocol number is increased to 2.0.6 as well, in case
    it matters.

    We have some arithmetic operations against snd_pcm_hw_param_t, thus
    bitwise isn't correct for it. Better to remove the flag to shut up
    sparse warnings.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
