  • 03cfe6f57   ALSA: support module on-demand loading for seq and timer ... Browse Code »

    If CONFIG_SND_DYNAMIC_MINORS is used, assign /dev/snd/seq and
    /dev/snd/timer the usual static minors, and export specific
    module aliases to generate udev module on-demand loading
    instructions:

    $ cat /lib/modules/2.6.33.4-smp/modules.devname
    # Device nodes to trigger on-demand module loading.
    microcode cpu/microcode c10:184
    fuse fuse c10:229
    ppp_generic ppp c108:0
    tun net/tun c10:200
    uinput uinput c10:223
    dm_mod mapper/control c10:236
    snd_timer snd/timer c116:33
    snd_seq snd/seq c116:1

    The last two lines instruct udev to create device nodes, even
    when the modules are not loaded at that time.

    As soon as userspace accesses any of these nodes, the in-kernel
    module-loader will load the module, and the device can be used.

    The header file minor calculation needed to be simplified to
    make __stringify() (supports only two indirections) in
    the MODULE_ALIAS macro work.

    This is part of systemd's effort to get rid of unconditional
    module load instructions and needless init scripts.

  • f90c06a2b   ALSA: Fix limit of 8 PCM devices in SNDRV_CTL_IOCTL_PCM_NEXT_DEVICE ... Browse Code »

    When compiled with CONFIG_SND_DYNAMIC_MINORS the ALSA core is fine
    to have more than 8 PCM devices per card, except one place - the
    SNDRV_CTL_IOCTL_PCM_NEXT_DEVICE ioctl, which will not enumerate
    devices > 7. This patch fixes the issue, changing the devices list
    organisation.

    Instead of adding new device to the tail, the list is now kept always
    ordered (by card number, then device number). Thus, during enumeration,
    it is easy to discover the fact that there is no more given card's
    devices.

    Additionally the device field of struct snd_pcm had to be changed to int,
    as its "unsignednity" caused a lot of problems when comparing it to
    potentially negative signed values. (-1 is 0xffffffff or even more then ;-)

    ordered (by card number, then device number). Thus, during enumeration,
    it is easy to discover the fact that there is no more given card's
    devices. The same limit was present in OSS emulation code. It has
    been fixed as well.

    Additionally the device field of struct snd_pcm is now int, instead of
    unsigned int, as there is no obvious reason for keeping it unsigned.
    This caused a lot of problems with comparing this value with other
    (almost always signed) variables. There is just one more place where
    device number is unsigned - in struct snd_pcm_info, which should be
    also sorted out in future.

    Modules: ALSA Core,ALSA Minor Numbers

    Remove the unused and undefined symbols SNDRV_DEVICE_TYPE_{MIXER,
    PCM_PLOOP,PCM_CLOOP}, and introduce a new symbol SNDRV_MINOR_GLOBAL
    for non-card-specific devices like the sequencer or the timer.

    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!
