Hello,
This is the v4 of my audio patches. This is a compile-fix revision, hopefully
fixing windows compile errors in "audio: use size_t where makes sense" and
compile errors introduced by changes on master in "audio: add audiodev
properties to frontends".
Regards,
Zoltan
Kővágó, Zoltán (14):
audio: reduce glob_audio_state usage
audio: basic support for multi backend audio
audio: add audiodev property to vnc and wav_capture
audio: add audiodev properties to frontends
paaudio: prepare for multiple audiodev
audio: audiodev= parameters no longer optional when -audiodev present
paaudio: do not move stream when sink/source name is specified
paaudio: properly disconnect streams in fini_*
audio: remove audio_MIN, audio_MAX
audio: do not run each backend in audio_run
paaudio: fix playback glitches
audio: remove read and write pcm_ops
audio: use size_t where makes sense
audio: fix memory leak reported by ASAN

Remove glob_audio_state from functions, where possible without breaking
the API. This means that most static functions in audio.c now take an
AudioState pointer instead of implicitly using glob_audio_state. Also
included a pointer in SWVoice*, HWVoice* structs, so that functions
dealing them can know the audio state without having to pass it around
separately.
This is required in order to support multiple simultaneous audio
backends (added in a later commit).

Audio functions no longer access glob_audio_state, instead they get an
AudioState as a parameter. This is required in order to support
multiple backends.
glob_audio_state is also gone, and replaced with a tailq so we can store
more than one states.

Finally add audiodev= options to audio frontends so users can specify
which backend to use when multiple backends exist. Not specifying an
audiodev= option currently causes the first audiodev to be used, this is
fixed in the next commit.
Example usage: -audiodev pa,id=foo -device AC97,audiodev=foo

To: qemu-devel; +Cc: Gerd Hoffmann
Have a pool of refcounted connections per server, so if the user creates
multiple audiodevs to the same pa server, it will use a single connection. (It
will still create different streams, so the user can manage those streams
separately in pulseaudio.)

This means you should probably stop using -soundhw (as it doesn't allow
you to specify any options) and add the device manually with -device.
The exception is pcspk, it's currently not possible to manually add it.
To use it with audiodev, use something like this:
-audiodev id=foo,... -global isa-pcspk.audiodev=foo -soundhw pcspk

Unless we disable stream moving, pulseaudio can easily move the stream
on connect, effectively ignoring the source/sink specified by the user.

There's already a MIN and MAX macro in include/qemu/osdep.h, use them
instead.

Pulseaudio normally assumes that when the server wants it, the client
can generate the audio samples and send it right away. Unfortunately
this is not the case with QEMU -- it's up to the emulated system when
does it generate the samples. Buffering the samples and sending them
from a background thread is just a workaround, that doesn't work too
well. Instead enable pa's compatibility support and let pa worry about
the details.

They just called audio_pcm_sw_read/write anyway, so it makes no sense
to have them too. (The noaudio's read is the only exception, but it
should work with the generic code too.)

I didn't really think about it. When I found the memory leak and
figured out it wasn't made by one of my patches, I just patched it on
top of my worktree.

I see. QEMU does 'stable' releases from time to time. These releases
contain security/bug fixes, and no new features. Sometimes important
memory leaks are fixed in stable release.
If this patch is at the beginning of your series, it might be selected
for stable release. If it is after you introduced your feature it won't.
If you have to respin your series, consider reordering this fix for
stable inclusion.
