Richard/Saul,

This Fixes [BUGID #488 #734]

As discussed, this enables the configuration options for qemu
audio for x86/x86-64 (limited to this for now). I did build and
boot testing (but couldn't directly test audio) for the impacted
qemu boards.

The commit message from the patch tells the rest of the story:

Enable audio for qemux86/qemux86-64 via the following kernel
configuration options.

  CONFIG_SOUND_OSS_CORE=y
  CONFIG_SOUND_OSS_CORE_PRECLAIM=y
  CONFIG_SND_RAWMIDI=m
  CONFIG_SND_SEQUENCER=y
  CONFIG_SND_OSSEMUL=y
  CONFIG_SND_MIXER_OSS=y
  CONFIG_SND_PCM_OSS=y
  CONFIG_SND_PCM_OSS_PLUGINS=y
  CONFIG_SND_SEQUENCER_OSS=y
  CONFIG_SND_RAWMIDI_SEQ=m
  CONFIG_SND_AC97_CODEC=m
  CONFIG_SND_ENS1370=m
  CONFIG_SND_INTEL8X0=m
  CONFIG_AC97_BUS=m

The mechanism to trigger these options is in the form of an
optional kernel feature that is only appended for qemux86
and qemux86-64, but is contained within the kernel tree.

This allows several things:

  - the options to be available/shared for all boards
  - the options to be in tree
  - to not add the options to every board, which unecessarily
    bloats the default configuration.

support OSS? I recall several years ago that OSS had drivers that Alsa 
did not and was needed for some boards - is that still the case? My 
feeling is, if possible, I'd like to just have alsa in our kernels and 
help reduce the raging redundancy in the audio API space.

I'd wondered about this too. In general I'd suggest Yocto's position is
to push for alsa drivers and see OSS as a legacy thing. As the author of
chunks of ALSA SoC code, I've put that into practise myself too! :)

Cheers,

Richard

alsa is the defacto / first choice for me.

That's partially why I chose to make this an
optional config block for this feature. That way
it is optional, and only applied to the specific qemu
images that we decided to add it for. All other kernels
and BSPs are unaffected.

If/when we get ALSA working for these qemu based machines,
we can easily drop this. But it looks like the only avenue
for the sound support immediately, so we slide it in
in as shallow a manner as possible.

Any and all patches to convert back to ALSA will be
happily merged! :)

alsa is the defacto / first choice for me.

That's partially why I chose to make this an
optional config block for this feature. That way
it is optional, and only applied to the specific qemu
images that we decided to add it for. All other kernels
and BSPs are unaffected.

If/when we get ALSA working for these qemu based machines,
we can easily drop this. But it looks like the only avenue
for the sound support immediately, so we slide it in
in as shallow a manner as possible.

Any and all patches to convert back to ALSA will be
happily merged! :)
