[PATCH v3 00/14] Cleanup deprecated audio features, take 2


From: Paolo Bonzini
Subject: [PATCH v3 00/14] Cleanup deprecated audio features, take 2
Date: Fri, 29 Sep 2023 10:50:53 +0200

In this version the QEMU_AUDIO_* options go away, but it is still
possible to pick a default audio backend from the list provided to
--audio-drv-list.  The code is still simplified a lot compared to
having all the legacy parsing code and the -audio-help function.
I had to keep QEMU_AUDIO_DRV=none because it is used by libqtest;
a possibility for the future could be to add a "-audio none" option
without a model.  For now I kept this setting as it is a subset of the
previous accepted values, and it can be deprecated separately.

At the end of this series, all devices can be configured with
-audiodev.  Therefore, I decided to forbid mixing the default
audio backend with audiodevs or with -nodefaults.

Patches 1-2 are Martin's patches that didn't end up in the previous
pull request.

Patches 3-4 change audio.c to use Error ** a bit more.

Patches 5-7 introduce the minimal code to create a default audio
backend.

Patches 8-11 introduce a machine property "audiodev" and plumb
it into all machines with an embedded sound card.

Patches 12-13 forbid some not-so-sensible usage of default
audio backends.

Patch 14 is an Error** propagation cleanup to avoid giving
Markus a heart attack if he ever looks at this code.  Or
at least moderating the intensity.

Paolo

v1->v2:
- do not expose audio encoding feature if VNC audio is not enabled [Daniel]
- add hint to error messages when -audiodev and default backend are mixed
- context changes due to shadowed variable fixes

v2->v3:
- adjust comment on "char *audiodev" field of MachineState
- use error_fatal instead of error_abort in OMAP and TSC210x's calls
  to AUD_register_card
- redo vt82c686 patches to remove aliased audiodev property
- fix leak in audio_driver_init when msg == false
- add patch to use Error in audio_init

Martin Kletzander (4):
  audio: Require AudioState in AUD_add_capture
  Introduce machine property "audiodev"
  hw/arm: Support machine-default audiodev with fallback
  hw/ppc: Support machine-default audiodev with fallback

Paolo Bonzini (10):
  ui/vnc: Require audiodev= to enable audio
  audio: allow returning an error from the driver init
  audio: return Error ** from audio_state_by_name
  audio: commonize voice initialization
  audio: simplify flow in audio_init
  audio: remove QEMU_AUDIO_* and -audio-help support
  vt82c686: Support machine-default audiodev with fallback
  audio: forbid mixing default audiodev backend and -audiodev
  audio: forbid default audiodev backend with -nodefaults
  audio: propagate Error out of audio_driver_init
