  To: qemu-devel; +Cc: Gerd Hoffmann, Eduardo Habkost

This patch series adds support to multiple audio backends.  Afterwards I
add support to multiple backends.  Audio fronteds gain a new audiodev
option to specify the id of the audiodev to use.  The audiodev= option
is required, unless you use the old environment variable based
configuration, in that case it must not used (and you can't use multiple
backends). 

Finally I also make mixeng usage optional, it can save us some useless
format converting when not needed.  Also makes easier to support formats
currently not supported by qemu (as only the backend has to support it,
not the mixeng).

For easier testing pull https://github.com/DirtYiCE/qemu.git tag 
audio-multi-v2.

Please review.

Changes from v1:
* added qemu_opts_print patch as it's still not merged
* splitted the big -audiodev and remove mixeng from backend commits
* tons of bugfixes and typo fixing

This will let us print options in a format that the user would actually
write it on the command line (foo=bar,baz=asd,etc=def), without
prepending a spurious comma at the beginning of the list, or quoting
values unnecessarily.  This patch provides the following changes:
* write id=, if the option has an id
* do not print separator before the first element
* do not quote string arguments
* properly escape commas (,) for QEMU

NetLegacy is just Netdev with some extra fields (name, vlan) and an
optional id.  This patch merges the two structs, and net_client_init1
got some extra checks to make sure only accept valid -netdev command
lines.  This is some extra work, but allows us to uniformly manage both
legacy -net and non-legacy -netdev in code.

This way we no longer need NetClientOptions and can convert Netdev
into a flat union.

Probably more logical if NetdevBase comes before Netdev.
No schematic changes.

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)

From: Kővágó, Zoltán @ 2015-08-21 15:37 UTC (permalink / raw
  To: qemu-devel; +Cc: Michael Roth, Gerd Hoffmann, Markus Armbruster

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-ambigous cases.  The qapi
flattening commits hopefully ensures that this change doesn't create
backward compatibility problems.

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

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.

From: Kővágó, Zoltán @ 2015-08-21 15:37 UTC (permalink / raw
  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.

+Adds a new audio backend @var{driver} identified by @var{id}.  There are
+global and driver specific properties.  Some values can be set
+differently for input and output, they're marked with @code{in|out.}.
+You can set the input's property with @code{in.@var{prop}} and the
+output's property with @code{out.@var{prop}}. For example:
+@example
+-audiodev alsa,id=example,in.frequency=44110,out.frequency=8000
+-audiodev alsa,id=example,out.channels=1 # leaves in.channels unspecified
+@end example
+
+Valid global options are:
+
+@table @option
+@item id=@var{identifier}
+Identifies the audio backend.
+
+@item timer-period=@var{period}
+Sets the timer @var{period} used by the audio subsystem in microseconds.
+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.
+
+@item in|out.channels=@var{channels}
+Specify the number of @var{channels} to use when using
+@var{fixed-settings}. Default is 2 (stereo).
+
+@item in|out.format=@var{format}
+Specify the sample @var{format} to use when using @var{fixed-settings}.
+Valid values are: @code{s8}, @code{s16}, @code{s32}, @code{u8},
+@code{u16}, @code{u32}. Default is @code{s16}.
+
+@item in|out.voices=@var{voices}
+Specify the number of @var{voices} to use.  Default is 1.
+
+@item in|out.buffer=@var{usecs}
+Sets the size of the buffer in microseconds.

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.

From: Kővágó, Zoltán @ 2015-08-21 15:37 UTC (permalink / raw
  To: qemu-devel; +Cc: Gerd Hoffmann

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.

From: Kővágó, Zoltán @ 2015-08-21 15:37 UTC (permalink / raw
  To: qemu-devel; +Cc: Michael Walle, Gerd Hoffmann

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

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

Currently this needs a workaround due to bug #74624 in pulseaudio.

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.)

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.

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.

This way we no longer need vararg functions, improving compile time
error detection.  Also now it's possible to check actually what commands
are supported, without needing to manually update ctl_caps.

I don't understand QAPI enough to understand why exactly this is needed
(so I would like to get feedback from somebody who actually understands
QAPI unions), but I have one comment below.

Why is the name "NumaDriver"? Below, the field is called "type", so why
not something like "NumaOptionType"?

It's needed so the option visitor can support nested structures properly 
without flattening them (or breaking backward compatibility).

There is some discussion here:
http://lists.nongnu.org/archive/html/qemu-devel/2015-06/msg04438.html

But basically the thing is that with new new opts visitor, unless we 
convert NumaOptions into a flat union, the user would have to type -numa 
node,node.nodeid=foo instead of -numa node,nodeid=foo which would break 
backward compatibility.

No particular reason other than the example in docs/qapi-code-gen.txt 
used driver.  The field is called type because in the non-flat union the 
discriminator is called type.

As long as somebody who understands QAPI says the changes make sense and
should work, I am OK with them if the following is changed:

In the docs/qapi-code-gen.txt example, the option is about an actual
blockdev driver, and the discriminator is really called "driver".

In this case, the field is called "type" and has nothing to do with
drivers, so something like NumaOptionType makes more sense.

Adding qapi & net folks to Cc.  Ping.

How to go forward with the QAPI bits in this series (Patches 1-9)?
Patch #1 got reviews from block folks.  Patch #3 has a comment from
Eduardo pending.  What about the other ones?  Fine as-is?  I remember
from the pre-2.4 freeze discussions that there at least was agreement
that flattening the qapi structs is the way to go.

I'd prefer if the qapi maintainers can pick up and merge these patches.
But I can also merge them via audio queue if I get reviews from the qapi
maintainers.

thanks,
  Gerd

Looks good overall to me, passed some simple testing.  Want do more
testing before merging, need to find some time for it.  Also we need to
get the qapi bits merged first.

There are some issues flagged by codestyle.pl.  For a good part they are
already in the existing code.  Sometimes you fixed the existing
problems, sometimes you didn't.  A few new issues (long lines for
example) are there too.  But given how many issues in existing audio
code we have I guess the easiest way to handle this is to fix it
afterwards with indent.

cheers,
  Gerd

Eduardo's comment was about s/NumaDriver/NumaOptionType/, and I didn't 
want to resend the whole series just to fix this small problem (as there 
will be other problems too, I think).  IIRC Markus still had opposition 
with patch #9 (support nested structs in OptsVisitor).

Still on my list of patches to review (seems to be a rather large list,
sadly).  I should get to it before Monday.

I'll leave it up to Markus on which tree is better for the qapi patches
to go through.

I guess this not in a hot path.  (If it were, I might suggest using
strchr() to skip to the next command, and fwrite() to output blocks of
data between commas, rather than putchar() at a time; but unless it
shows up in a benchmark that might be premature optimization)

However, note that I may be touching the signature of these functions in
one of my pending patches (last RFC was here[1], although I'm currently
rebasing on top of Markus v4/v5 of introspection, and may yet tweak how
things work before my next post)

The subject line is a one-line "what", and the commit body should be the
"why" - all but the most trivial "what" deserve a non-empty commit body.

In particular, I think you NEED to mention in the commit body that the
conversion does not strictly follow the QMP wire equivalency between
simple and flat unions as spelled out in docs/qapi-code-gen.txt, but
that this is okay because we do not have any QMP commands that use the
NumaOptions type to begin with (so there is no observable change to any
commands sent over QMP).  Meanwhile, mention that the change is made to
convert the generated C code into something that will ultimately be
easier to work with.

Now that commit 0f61af3 has landed, you'll have to rebase your patch to
use 'switch (object->type) {' here.  Basically, the conversion from
simple to flat union now (temporarily) generates a different tag name
for simple unions than for flat unions (although I have a pending patch
[1] that solves that, but by using object->type everywhere).

...this part is okay (you are creating a new base type, which consists
of a single common member named 'type' of the new enum type),...

[By the way, while the base type is currently required, I have a pending
patch that would add syntax sugar to avoid it, so maybe you want to wait
for my patch [2] to land?

[2] https://lists.gnu.org/archive/html/qemu-devel/2015-08/msg02321.html

so you could write 'base': { 'type': 'NumaDriver' } directly in the flat
union, instead of having to declare NumaCommonOptions]

...but this part is missing one piece of the conversion (to be strictly
QMP compatible with the simple union, each branch of the flat union must
be a NEW type that contains a single member 'data' of the old type).

That is, if we were TRYING to preserve QMP compatibility, we'd need:

{ 'struct': 'NumaNodeOptionsWrapper',
  'data': { 'data': 'NumaNodeOptions' } }
{ 'union': 'NumaOptions', 'base': 'NumaCommonOptions',
  'discriminator': 'type', 'data': {
    'node': 'NumaNodeOptionsWrapper' } }

The difference on the wire is that the old simple union, or with my
version of the flat union, would allow:

{ 'command': 'foo', 'arguments': {
    'type': 'numa', 'data': { 'nodeid': 1 } } }

while the new flat union as you wrote it reduces nesting:

{ 'command': 'foo', 'arguments': {
    'type': 'numa', 'nodeid': 1 } }


That said, there is another point of view to worry about, which is what
C structures get generated.  Here, I'm using output after Markus' v4
series is applied (since it is slightly more legible than current
qemu.git mainline generated output) (and although I still have further
pending patches that improve it further).  The pre-patch simple union
would generate:

struct NumaOptions {
    NumaOptionsKind kind;
    union { /* union tag is @kind */
        void *data;
        NumaNodeOptions *node;
    };
};

and your version would generate (notice the rename from 'kind' to 'type'):

struct NumaOptions {
    /* Members inherited from NumaCommonOptions: */
    NumaDriver type;
    /* Own members: */
    union { /* union tag is @type */
        void *data;
        NumaNodeOptions *node;
    };
};

but my proposal to keep QMP compatibility would generate an incompatible
layer of boxing:

struct NumaOptions {
    /* Members inherited from NumaCommonOptions: */
    NumaDriver type;
    /* Own members: */
    union { /* union tag is @type */
        void *data;
        NumaNodeOptionsWrapper *node;
    };
};


So, in conclusion, since no existing QMP command used the old type, and
your choice of changes preserved the generated struct layout, it means
we have no change to command line parsing and no user-visible changes to
worry about.  And I'm fine with this patch, once you improve the commit
message and rebase to mainline:

The enum name is not ABI (we can name it whatever makes sense), but does
show up in the C code that interacts with the generated type.  In fact,
if you could name the enum type 'NumaOptionsKind', then the C enum name
would not change (staying at NUMA_OPTIONS_KIND_NODE instead of your
change to NUMA_DRIVER_NODE).  Except that right now, the qapi generator
doesn't allow user-defined types ending in 'Kind'.  :(

I don't know if naming it NumaDriver makes sense; and so your suggestion
of naming it NumaOptionsType may be better in the long run.  It would
make your C enum become NUMA_OPTIONS_TYPE_NODE.

Or maybe you wait for me to do a followup patch to the qapi generator to
allow user-defined types ending in 'Kind'.

I'm really hoping to fix QMP netdev_add to use a flat union type from
the get-go rather than its current type-unsafe gunk.  It may be safer
from the point of view of this patch to wait for that to land first
(among others, we'll want:
https://lists.gnu.org/archive/html/qemu-devel/2015-08/msg02093.html)

So I'm reluctant to review this right now, if it will just add churn
into getting that part done correctly.

Don't throw this away just yet, because I'm not sure if QMP netdev_add
needs to interact with command-line NetdevLegacy.  But be aware that it
is still an area under active debate/development.

Nice; you've already done some of the work that I saw as needing to be
done for my plans to convert QMP netdev_add to use a flat union instead
of 'gen':false.

Conflicts with my s/kind/type/ in

whoever goes in first gets to avoid the obvious merge conflict

I may end up using a modified version of your patch in my submission for
QMP netdev_add, while still avoiding the merge of NetdevLegacy (I'm not
sold on that one yet, because it exists only for the command line and
not for QMP, while we want to make QMP become typesafe).

Same question as in 3 about whether 'driver' is the right name for the

So the bulk is mechanical 1:1 replacement, and the qapi change adds a

You know, if we could teach qapi to allow a user-named type with 'Kind'
as the suffix, we wouldn't have quite as much churn :)

Hmm; maybe 'Driver' really is the right name for this enum.

I'd document id and vlan prior to the initial 'Since 1.2', then leave
the only thing after that line to be just the list of when later drivers
were added to the union.  Actually, depending on what I decide about
4/49, we may not even be adding vlan and name, and id might not be
optional, since that was just NetdevLegacy.  And if we do merge
NetdevLegacy, then it's better to have separate lines for @vlan and
@name, as well as the documentation of when they can be set.

QMP wise (if we were to use Netdev in QMP), this is changing:

{ "command":"foo", "arguments": {
    "id":"abc", "opts" { "type":"dump", "data": {
        "len":1024, "file":"/path/to/foo" } } } }

into

{ "command":"foo", "arguments": {
    "id":"abc", "type":"dump",
    "len":1024, "file":"/path/to/foo" } }

Wow - removing two levels of nesting in one patch.  Even cooler, this
LOOKS a lot like what QMP 'netdev_add' already parses :)

The corresponding C code loses one layer of boxing (because, as I
already pointed out on 3, converting from simple to flat union without
creating data wrappers loses one layer of nesting in QMP with no change
to the nesting in the matching generated C structure).

So, if we can _avoid_ merging in NetdevLegacy stuff here (but that has
knock-on effects, because my hack to use 5/49 without 4/49 doesn't quite
work with the sed statement you used here), then you have just created
the solution for netdev_add.  I'll use your patch as a starting point,
coupled with my pending work to allow a boxed flat union as the direct
argument to a QMP command.

This is where I'm not completely sold that the merge from NetdevLegacy
makes sense. Like I said, I'm playing with it some on my tree.

Just code motion; doesn't affect generated output or semantics.
Reviewed-by: Eric Blake <eblake@redhat.com>

But does depend on my earlier comments about whether the merge with
NetdevLegacy was right. So it may hit merge conflicts, depending on
where I go with that; in which case dropping the patch altogether may be
easiest.

Give me some more time to think about 8 and 9 (it's nearly the start of
a 3-day weekend for me). I know I said I'd look at these patches before
Monday, but for now you'll have to live with my review on just 1-7.  Oh
well. I know what I'm starting on next week when I return :)

And we still have plenty of time before qemu 2.5 to get things right.

Okay, I've rebased the patches to master and applied (some of) the 
changes suggested by Eric.  Since it looks like there are still some 
problems with the qapi parts, it may be better if I split out the qapi 
patches into a separate series, and go back to the audio patches when 
the qapi bits are merged.  Should I go ahead?

Given the size of this series, splitting it up into separately
reviewable parts sounds like an excellent idea.
