  • a67ff6a54   ALSA: module_param: make bool parameters really bool ... Browse Code »

    module_param(bool) used to counter-intuitively take an int. In
    fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
    trick.

    It's time to remove the int/unsigned int option. For this version
    it'll simply give a warning, but it'll break next kernel version.

  • 4b3be6afa   ALSA: sound: Move dereference after NULL test and drop unnecessary NULL tests ... Browse Code »

    In pcm.c, if the NULL test on pcm is needed, then the dereference should be
    after the NULL test.

    In dummy.c and ali5451.c, the context of the calls to
    snd_card_dummy_new_mixer and snd_ali_free_voice show that dummy and pvoice,
    respectively cannot be NULL.

    A simplified version of the semantic match that detects this problem is as
    follows (http://coccinelle.lip6.fr/):

    //
    @match exists@
    expression x, E;
    identifier fld;
    @@

    * x->fld
    ... when != \(x = E\|&x\)
    * x == NULL
    //

  • 9b151fec1   ALSA: dummy - Add debug proc file ... Browse Code »

    Added the debug proc file to see or change the snd_pcm_hardware fields
    to emulate. The parameters can be changed by writing to a proc file like:

    # echo periods_min 4 > /proc/asound/card1/dummy_pcm

  • a68c4d113   ALSA: dummy - Fake buffer allocations ... Browse Code »

    Instead of allocating the real buffers, use a fake buffer and ignore
    read/write in the dummy driver so that we can save the resources.
    For mmap, a single page (unique to the direction, though) is reused
    to all buffers.

    When the app requires to read/write the real buffers, pass fake_buffer=0
    module option at loading time. This will get back to the old behavior.

  • b142037b4   ALSA: dummy - Better jiffies handling ... Browse Code »

    In the system-timer mode, snd-dummy driver issues each tick to update
    the position. This is highly inefficient and even inaccurate if the
    timer can't be triggered at each tick.

    Now rewritten to wake up only at the period boundary. The position
    is calculated from the current jiffies.

  • c631d03c6   ALSA: dummy - Support high-res timer mode ... Browse Code »

    Allow snd-dummy driver to use high-res timer as its timing source
    instead of the system timer. The new module option "hrtimer" is added
    to turn on/off the high-res timer support. It can be switched even
    dynamically via sysfs.

  • 9004acc70   [ALSA] Remove sound/driver.h ... Browse Code »

    This header file exists only for some hacks to adapt alsa-driver
    tree. It's useless for building in the kernel. Let's move a few
    lines in it to sound/core.h and remove it.
    With this patch, sound/driver.h isn't removed but has just a single
    compile warning to include it. This should be really killed in
    future.

  • a182ee987   [ALSA] continue on IS_ERR from platform device registration ... Browse Code »

    I previously only concerned myself with sound/isa. When I now checked
    for more platform_device_register_simple() usages in ALSA I found a
    couple more drivers that needed the same patches as already submitted
    for all the ISA drivers.
    This first one is the continue-on-iserr patch for sound/drivers. This
    gets them all.

    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!
