This patch adds structures into qapi to replace the existing
configuration structures used by audio backends currently. This qapi
will be the base of the -audiodev command line parameter (that replaces
the old environment variables based config).
This is not a 1:1 translation of the old options, I've tried to make
them much more consistent (e.g. almost every backend had an option to
specify buffer size, but the name was different for every backend, and
some backends required usecs, while some other required frames, samples
or bytes). Also tried to reduce the number of abbreviations used by the
config keys.
Some of the more important changes:
* use `in` and `out` instead of `ADC` and `DAC`, as the former is more
user friendly imho
* moved buffer settings into the global setting area (so it's the same
for all backends that support it. Backends that can't change buffer
size will simply ignore them). Also using usecs, as it's probably more
user friendly than samples or bytes.
* try-poll is now an alsa backend specific option (as all other backends
currently ignore it)

Notes:
Changes from v4:
* documentation fixes
* renamed pa's source/sink to pa-in/pa-out
* per-direction options changed per Markus Armbruster's comments
Changes from v2:
* update copyright, version numbers
* remove #optional
* per-direction options are now optional (needed for qobject_object_visitor_new_str)
* removed unnecessary AudiodevNoOptions
* changed integers to unsigned

Markus? Eric? Can I get an ack for this patch?
Series looks good to me overall, testing looks good too, I'd like to
merge it together with some other pending audio bits soonish.
thanks,
Gerd

The name says "len" (for length), the comment says "size" and by its
unit implies "duration".
In the QMP schema, we traditionally prefer longhand like "length" over
abbreviations like "len".
What about calling it @buffer-capacity?

Permit me to indulge in a little nitpicking... If you want to refer to
the Advanced Linux Sound Architecture, that's spelled ALSA. If you want
to refer to the enumeration value, consider putting it in double quotes:
"alsa".
Here, 'the ALSA backend', 'the "alsa" backend', and 'the alsa backend'
would all work for me. Your choice.
More occurences of 'the FOO backend' and 'the FOO audio backend' below.

But I'd definitely use ALSA here.

Here, you're already using the name PulseAudio rather than the

I had to include an enum for audio sampling formats into qapi, but that
meant duplicating the audfmt_e enum. This patch replaces audfmt_e and
associated values with the qapi generated AudioFormat enum.
This patch is mostly a search-and-replace, except for switches where the
qapi generated AUDIO_FORMAT_MAX caused problems.

This patch adds documentation of an -audiodev command line option, that
deprecates the old QEMU_* environment variables for audio backend
configuration. It's syntax is similar to existing options (-netdev,
-device, etc):
-audiodev driver_name,property=value,...
Although now it's possible to specify multiple -audiodev options on
command line, multiple audio backends are not supported yet.

+Sets the timing policy (between 0 and 10, where smaller number means
+smaller latency but higher CPU usage). Use -1 to use buffer sizes

Note: The old vars will continue to work, and possibly it makes sense to
keep at least QEMU_AUDIO_DRV (which I think is the only one used by
libvirt) working a bit longer than the minimal deprecation period.
Also: This is a first step only, there is more in the pipeline, where
you can assign sound cards to backends (simliar to -netdev). You might
want wait for this to land before start working on libvirt support, or
at least keep in bind this is coming when designing things.
cheers,
Gerd

We can do the trivial replacement of QEMU_AUDIO_DRV with -audiodev
without much difficulty - just a matter of tweaking the CLI generator
and tests.
The full support with XML configurability doesn't need to block us
dropping use of QEMU_AUDIO_DRV.

Libvirt lacks proper support for the existing multi-seat features in
QEMU. This audio stuff might be a good motivation to finally implement
the full multi-seat feature set.

Daniel

Audio drivers now get an Audiodev * as config paramters, instead of the
global audio_option structs. There is some code in audio/audio_legacy.c
that converts the old environment variables to audiodev options (this
way backends do not have to worry about legacy options). It also
contains a replacement of -audio-help, which prints out the equivalent
-audiodev based config of the currently specified environment variables.
Note that backends are not updated and still rely on environment
variables.
Also note that (due to moving try-poll from global to backend specific
option) currently ALSA and OSS will always try poll mode, regardless of
environment variables or -audiodev options.

Notes:
Currently audiodev_get_pdo_in is essentially:
return (AudiodevPerDirectionOptions *) dev->u.none.in;
This depends on in and out always be the first two member of backend specific
options, and the compiler not playing tricks with the union/pointers, so I
went with a safer version. This also catches type coversion errors for a small
runtime performance penalty.

This should check has_in before overwriting. It'll work correctly when
called from audio_legacy.c, but when using -audiodev it will overwrite
the options passed by user (and leak memory) when called from
audio_validate_opts. I'll fix it in the next update.

Ping. 4.0 freeze is next tuesday. Any chance for a v6 early enough
that we have a chance to get the first chunk into 4.0? Monday latest,
preferably earlier ...

I blame it on my horrible time management. Also the recent sdl/audio
patches generated some conflicts, I had to solve them first. And magic
errors like "'vfio-pci' is not a valid device model name" after update.

Hi,

Try a full rebuild then. I see strange errors now and then too, that
fixed it. Seems the qemu build fails now and then that an object file
needs a rebuild.
