They are required for flat unions (you still have to allocate the
structs).

From: Kővágó, Zoltán <dirty.ice.hu@gmail.com>
The current OptsVisitor flattens the whole structure, if there are same
named fields under different paths (like `in' and `out' in `Audiodev'),
the current visitor can't cope with them (for example setting
`frequency=44100' will set the in's frequency to 44100 and leave out's
frequency unspecified).
This patch fixes it, by always requiring a complete path in case of
nested structs. Fields in the path are separated by dots, similar to C
structs (without pointers), like `in.frequency' or `out.frequency'. You
must provide a full path even in non-ambiguous cases.
To keep backward compatibility, this new feature can be disabled when
creating a new OptsVisitor, in that case it will work identical to
previous versions.

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)

Do you want to claim 2015-2019 now? But ultimately what you put is your
call, so don't treat my suggestion as a legal mandate.

Also, we now have support for empty branches in a flat union, so do you
really need this type, or...

No need to use the '#optional' tag any more; the doc generator now takes
care of that.

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.

To: qemu-devel; +Cc: Gerd Hoffmann
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.

+Default is 10000 (10 ms).
+
+@item in|out.fixed-settings=on|off
+Use fixed settings for host audio. When off, it will change based on
+how the guest opens the sound card. In this case you must not specify
+@var{frequency}, @var{channels} or @var{format}. Default is on.
+
+@item in|out.frequency=@var{frequency}
+Specify the @var{frequency} to use when using @var{fixed-settings}.
+Default is 44100Hz.

To: qemu-devel; +Cc: Gerd Hoffmann, Paolo Bonzini
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.

This uses the options visitor, roughly like -netdev. Depends on your
options visitor enhancements. Is there any particular reason not to do
it like -blockdev and -display, with qobject_input_visitor_new_str()?
I'm asking because I'd very much like new code to use
qobject_input_visitor_new_str() rather than the options visitor.
Today, the options visitor looks like an evolutionary dead end. My
command-line qapification (still stuck at the RFC stage, hope to get it
unstuck this year) relies on qobject_input_visitor_new_str(). The goal
is to convert *all* of the command line to it.
I suspect your series uses the options visitor only because back when
you started, qobject_input_visitor_new_str() didn't exist.

Yes, this patch series is a bit old, and at that time this was the best
I could do. I can look into it this (probably only on the weekend
though), it looks like it supports foo.bar=something syntax, so I don't
have to specify a json on the command line...

The dotted key syntax and how it relates to JSON is documented in
util/keyval.c.
If you have further questions on this stuff, please don't hesitate to
ask me.
If you get to the point where you feel your (beefy) series has gotten
stuck on the conversion away from the options visitor, let's discuss how
to best get it unstuck.
Thanks!

I briefly looked at converting this single patch, and of course I ran
into a few issues.
The audio_legacy code currently creates a QemuOpts from the environment
variables. This had a nice effect that once I converted the options, I
could print them with qemu_opts_print, helping the user how to convert
the old env variables to -audiodev, since some of the conversions are
not so trivial/straightforward.
I converted them to QDict, which complicated things a bit since now I
have to do proper nesting (until now I could just set key to "foo.bar"
and it worked), especially in the *_to_usecs functions that accessed
previously set options. Also while there's
qobject_input_visitor_new_str, I couldn't find anything that would do
the reverse. I wrote a quick and dirty function that does this, it
appears to work, but unlike QemuOpts, QDict is unordered, and writing
-audiodev id=foo,driver=alsa,rest... is IMHO more logical than writing
them alphabetically. Or maybe it's just me who's too picky and it
doesn't matter.
I was thinking about creating an Audiodev (the qapi type) directly would
be better, then somehow print it with reflection. While this is not a
typical use of qapi, at least qmp_qom_list creates qapi objects
directly, so I assume it's ok. This would save us from parsing
essentially the same data twice, and the code to deal with an Audiodev
is simpler that dealing with the generic QDicts and QObjects, but it
would require some refactoring.
The second problem: with my patched options visitor, nested structs were
required in qapi, the options visitor unconditionally filled them. With
qobject_input_visitor, I have to mark them optional, otherwise the user
have to specify at least one option from the nested structs.
Essentially, if you have something like this:
{ 'struct': 'Inner', 'data': [ '*foo': 'str' ] },
{ 'struct': 'Outer', 'data': [ '*bar': 'Inner' ] }
With the old parser you couldn't specify {}, while with
qobject_input_visitor_new_str, you can's specify { 'bar': {} } without
using JSON. I'm not sure which is the better, but with the old behavior
at least you could mark nested structs as required and not worry about
checking has_x every time.
Now that I wrote all this down, I'm starting to think that
qobject_input_visitor is good, and I should just properly check the
fields (or give them default values). Rubber duck debugging, I think.

Zoltan

Yes, it's perfectly fine.

Can we just drop the nesting?
Have a look at DisplayOptions (qapi struct used to store -display
options). It's a union, has some common base fields, and the
discriminator field (type in that case) decides which of the data
branches is used. And on the command line I can do stuff like this:
-display gtk,full-screen=on,zoom-to-fit=on
^^^^^^^^^^^ in struct DisplayGTK
^^^^^^^^^^^ common base field
Audiodev should be able to do the same to support backend-specific
options without nesting.
cheers,
Gerd

I think that union thing works, the problem is with input and output
settings, because they're common. Currently you can write in.frequency
and out.frequency, in and out are both AudiodevPerDirectionOptions. The
alternative would be to flatten the whole structure and have
in_frequency, out_frequency and everything else duplicated in Audiodev

Ah, right, I remember now.

Which might be not that bad after all. The parser code is generated.
The audio drivers (where the settings are looked up) have separate code
paths for in and out anyway. So a per-direction struct probably
wouldn't reduce the amout of code in the drivers. Driver-specific
per-direction options are easier to deal with too I think (not sure we
have them though).
Property names should use dashes not underscores btw (i.e.
in-frequency).

Gerd

It supports both, i.e. this ...
qemu -display gtk,full-screen=on
... and this ...
qemu -display '{ "type": "gtk", "full-screen": true }'
... has the same effect.

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.

To: qemu-devel; +Cc: Gerd Hoffmann, Michael Walle
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

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

Those MIN/MAX are smarter than the ones in "qemu/osdep.h", I'd keep them
moving them there.

Yes, but only when using gcc (or clang when it emulates gcc).
Unfortunately, they work differently when one of the expressions has
side effects, which is a disaster waiting to happen (when some poor folk
finally tries to compile it with a non-gcc compiler).
Or do we support any compilers beside gcc and clang? Because if not,
sure, do it, just remove the #ifdef and keep only the gcc version.

Zoltan

We already use the typeof extension:
$ git grep typeof|wc -l
145
For MIN/MAX I'd use rather use the __auto_type extension.

Yes, this is checked by the ./configure script:
1850 # Check whether the compiler matches our minimum requirements:
...
1859 # error You need at least Clang v3.4 to compile QEMU
...
1864 # error You need at least GCC v4.8 to compile QEMU
...
1867 # error You either need GCC or Clang to compiler QEMU

Fair enough. I've tried to check the documentation for supported
compilers, but I haven't found any info. Well, I didn't look at the
configure script, I admit that.
This is what I came up with:
#ifndef MIN
#define MIN(a, b) ( __extension__ ({ \
__auto_type _a = (a); \
__auto_type _b = (b); \
_a > _b ? _b : _a; \
}))
#endif
#ifndef MAX
#define MAX(a, b) ( __extension__ ({ \
__auto_type _a = (a); \
__auto_type _b = (b); \
_a < _b ? _b : _a; \
}))
#endif
I changed it a bit, since a and b are the macro parameters, so they are
the variables that we should put into parentheses, and I renamed ta/tb
to _a/_b, this way they're less likely to clobber some other variables.
To be honest, we could probably drop the __extension__ keyword too,
we're not compiling with -pedantic. Other than audio_MIN and audio_MAX,
it only appears in the DO_UPCAST macro.

Zoltan

You haven't found any info because the minimum requirements are not well
documented on the wiki.

Sounds good. Now the parentheses around a/b are not necessary.
I wonder however if it wouldn't be cleaner to previously add:
#ifdef MIN
# undef MIN
#endif
and for MAX, rather than only use these macros if undefs.

Fine with me!
If you have this patch ready, you can send it alone out of this series,
no need to resend this whole series for this patch.
Thanks,

Um, this broke a few things. It also means until now in some cases it
used some random definition of MIN/MAX instead of the one in the header.
/home/dirty_ice/qemu/include/qemu/osdep.h:240:5: error: ‘__auto_type’
used with a bit-field initializer
/home/dirty_ice/qemu/include/qemu/osdep.h:247:35: error: braced-group
within expression allowed only inside a function
The first one is fixable with an explicit cast (ugly but works), but the
second one is more problematic. It means we can't write stuff like
USBPort uports[MAX(MAXPORTS_2, MAXPORTS_3)];
when not in a function. So we either need a dumb version of MIN/MAX, or
scrape the idea altogether.

There will be adjustmets to other patches too, so I think I'll just
consolidate them.

const_max() for stuff which is a compile time constant maybe?

audio_run is called manually by alsa and oss backends when polling.
In this case only the requesting backend should be run, not all of them.

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.)

about replay version update, this patch looks sane to me.
Returning size_t seems enough (no need to return a ssize_t).

While this certainly makes sense I don't think this should be done as
part of this patch series, it is already big enough as-is.

Usage notes: hw->samples became hw->{mix,conv}_buf->size, except before
initialization (audio_pcm_hw_alloc_resources_*), hw->samples gives the
initial size of the STSampleBuffer. The next commit tries to fix this
inconsistency.

This patch removes the samples member from HWVoiceIn and HWVoiceOut.
Backends can specify buffer size via the newly added buffer_size_in and
buffer_size_out functions in audio_pcm_ops. They are optional, if not
defined qemu will fall back to some built-in constant.
Signed-off-by: Kővágó, Zoltán <DirtY.iCE.hu@gmail.com>

Not sure if this is necessary. At first it seemed like a good idea to
have a function so that backends can compute the size on demand when
needed and things like that, but currently it's just a burden. The only
good feature is that it allows a backend to not define a function and
let the audio subsystem choose a default value, but the same could be
achieved by specifying that hw->samples = 0 means use a default value.
So if you guys agree, I'll remove this patch. Maybe add an -audiodev
parameter to change it, overriding whatever the backends supplies.

To: qemu-devel; +Cc: Gerd Hoffmann
This commit removes the ad-hoc rate-limiting code from noaudio and
wavaudio, and replaces them with a (slightly modified) code from
spiceaudio. This way multiple write calls (for example when the
circular buffer wraps around) do not cause problems.

error detection. Also now it's possible to check actually what commands
are supported, without needing to manually update ctl_caps.

This will allow us to disable mixeng when we use a decent backend.
Disabling mixeng have a few advantages:
* we no longer convert the audio output from one format to another, when
the underlying audio system would just convert it to a third format.
We no longer convert, only the underlying system, when needed.
* the underlying system probably has better resampling and sample format
converting methods anyway...
* we may support formats that the mixeng currently does not support (S24
or float samples, more than two channels)
* when using an audio server (like pulseaudio) different sound card
outputs will show up as separate streams, even if we use only one
backend
Disadvantages:
* audio capturing no longer works (wavcapture, and vnc audio extension)
* some backends only support a single playback stream or very picky
about the audio format. In this case we can't disable mixeng.
However mixeng is not removed, only made optional, so this shouldn't be
a big concern.

In fact, the qapi generator had special code to detect and reject
#optional tags for some six months (from commit 1d8bda128d2 to
67ab1ce9263), just to ensure patches in flight don't add them. This one
has been in flight for even longer.

The whole AudiodevPerDirectionOptions struct is marked with 'Since:
4.0', so I don't think it's necessary.

Oh right. It's less common to see incremental additions to a type within
a single release, but you are right that the per-member tag is only
needed when an older release exposed the type you are extending.

To: qemu-devel; +Cc: Gerd Hoffmann
The bit shifting trick worked because the number of bytes per frame was
always a power-of-two (since QEMU only supports mono, stereo and 8, 16
and 32 bit samples). But if we want to add support for surround sound,
this no longer holds true.

Which currently only means removing some checks. Old code won't require
more than two channels, but new code will need it.

With stereo playback, they need about 375 minutes of continuous audio
playback to overflow, which is usually not a problem (as stopping and
later resuming playback resets the counters). But with 7.1 audio, they
only need about 95 minutes to overflow.
After the overflow, the buf->prod % USBAUDIO_PACKET_SIZE(channels)
assertion no longer holds true, which will result in overflowing the
buffer. With 64 bit variables, it would take about 762000 years to
overflow.

Hm, I agree with the signed part, but I'm not sure about the size_t
part. Granted, there's a big problem if buf->prod - buf->cons can't be
representated on 32 bits, but still I'd rather use int64_t in this case
and prevent this potential truncation on 32-bit platforms.

For a such series with refactors and typedefs changes, I recommend you
to use/setup the scripts/git.orderfile script: Headers are showed first,
then the sources, which makes review easier (no need to constantly scroll).
No need to resend, but if you have to respin, this will be appreciated.
Regards,
Phil.
