This series of patches adds a new -audiodev command line option to
specify audio subsytem parameters instead of environment variables.
This will later allow us to specify multiple audio backends. The
syntax is something like this:
-audiodev driver_name,id=id,property=value,...
like:
-audiodev alsa,id=foo,frequency=8000,channels=1
This series also convert numa and netdev qapi to flat unions, to avoid
extra complexity in OptsVisitor. Please refer to the thread at v2
patch.
You are encouraged check whether I break anything during the
refactorings (especially at netdev and various audio backends). For
easier testing, pull https://github.com/DirtYiCE/qemu.git tag
audio-cmdline-v3.
Please review (especially the qapi refactoring I did...)
Changes from v2:
* consistency, style issues in audio qapi
* converted NumaOptions and Netdev and friends to flat union
* OptsVisitor: only full paths accepted
* qemu_opts_print: hopefully produces valid command line in all cases
* other small fixes...
Changes from v1:
* updated to master, removed commits already merged
* now every time-related option takes usecs
* some small fixes
Kővágó, Zoltán (8):
qapi: support implicit structs in OptsVisitor
qapi: convert NumaOptions into a flat union
qapi: change Netdev and NetLegacy into a flat union
qapi: qapi for audio backends
qapi: support nested structs in OptsVisitor
opts: produce valid command line in qemu_opts_print
audio: use qapi AudioFormat instead of audfmt_e
audio: -audiodev command line option

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

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 and oss backend specific option (as all other
backends currently ignore it)

Changes from v2 patch:
* documentation fixes
* rename mmap -> try-mmap, buffer -> buffer-len
* id is now required
* converted into flat unions
* renamed alsa's and oss's in an out, because it was incompatible with
with flat union
Changes from v1 patch:
* every time-related field now take usecs (and removed -usecs, -millis suffixes)
* fixed inconsisten optional marking, language issues
Changes from v2 RFC patch:
* in, out are no longer optional
* try-poll: moved to alsa and oss (as no other backend used them)
* voices: added (env variables had this option)
* dsound: removed primary buffer related fields
Changes from v1 RFC patch:
* fixed style issues
* moved definitions into a separate file
* documented undocumented options (hopefully)
* removed plive option. It was useless even years ago so it can probably safely
go away: https://lists.nongnu.org/archive/html/qemu-devel/2012-03/msg02427.html
* removed verbose, debug options. Backends should use trace events instead.
* removed *_retries options from dsound. It's a kludge.
* moved buffer_usecs and buffer_count to the global config options. Some driver
might ignore it (as they do not expose API to change them).
* wav backend: removed frequecy, format, channels as AudiodevPerDirectionOptions
already have them.

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 previous
two commits hopefully ensures that this change doesn't create backward
compatibility problems.

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 and id=, if the option has an id
* do not print separator before the first element
* do not quote string arguments which only contains letters or numbers
* properly escape commas (,) for QEMU, apostrophe (') for shell
Signed-off-by: Kővágó, Zoltán <DirtY.iCE.hu@gmail.com>

Chages from v2:
* print id=
* proper value escaping (apostrophe and comma)
* renamed d_sep -> separator

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 @ 2015-06-18 16:43 UTC (permalink / raw)
To: qemu-devel; +Cc: Paolo Bonzini, Gerd Hoffmann
This patch adds an -audiodev command line option, and deprecates the
QEMU_* environment variables for audio backend configuration. It's
syntax is similar to existing options (-netdev, -device, etc): -audiodev
driver_name,property=value,...
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.
Although now it's possible to specify multiple -audiodev options on
command line, multiple audio backends are not supported yet.

Changes from v2:
* fixed alsa threshold
* updated to audio qapi changes
Changes from v1:
* updated to everything usecs without suffix
* better rounding when converting between usecs and frames/samples/bytes
* bugfixes in audio_legacy.c
* fixed code broken by qemu_opts changes by Markus

+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.

Re patch v3 1/8 -- apparently I was not around when the
start_implicit_struct() and end_implicit_struct() visitor callbacks were
introduced, so I don't know what they are good for, but on the surface,
that patch might even be correct. I can't tell.
Re patch v3 5/8, ie. this patch -- if there has been some kind of
"master blurb" for this feature, ie. justification for nested structs,
I'm unaware of it. (I'm not getting qemu-devel email, just personal
Cc's.) Can you please send me a link into the archive where this feature
is justifed / discussed?
I have one related, and one independent note here:
(1) The related note -- OptsVisitor was introduced in commit eb7ee2cbeb.
You can see in the commit message that "union of flat structures" was a
foundational design trait for OptsVisitor, so if you want nested
structs, it's not a "bug to fix", but a new feature to add.
(Namely, refer to the allowed members of "struct for discriminator case
1" -- they can only be scalar members, or restricted format lists for
repeating optargs. Structure nesting is not allowed on any level.)
The objective was to support then-existent command lines (ie. parse
options into QAPI schemas). As far as I (vaguely) recall, Eric has since
(independently) flattened a bunch of QAPI structs as well. So I'm unsure
if and why nested structs are "again" a "thing".
(In any case this should not be taken as my opposition; I'm just
uninformed. That link I mentioned above could inform me.)
(2) The independent note. OptsVisitor is one of the
hardest-to-understand things I've implemented. It has always been hard
to understand for myself. As far as I recall, I struggled in my mind to
cover all corner cases and prove stuff right. Later I was "asked" to add
range support to it (ie. turn a range like 3-7 into a list of integers
3, 4, 5, 6, 7) and I was sweating bloody bullets to avoid regressions.
So, this code requires careful tiptoeing. I do not want to discourage
changes to it (and I certainly encourage reviewers to look at your
patches). I'm just saying I personally can't be your reviewer. I lost
this context long ago, I dread looking at this code again, and I don't
feel safe saying either yay or nay.
You could *almost* accuse me of having thrown this code over the fence.
My only excuse (a good one though) is that I only wrote this code
because I was asked to. (If you're familiar with the Bioshock universe,
I heard "would you kindly".)
I'm told that this code has proved somewhat useful, which I'm glad
about, but I really can't support it. Sorry about that. So, I'm neither
acking nor nacking; don't wait for my feedback.
(Apologies for the wall of text, but I guess it's better to say "sorry
can't help you" in too many words than not reacting at all.)
Thanks
László (since we're using Hungarian accents in this thread :))

Actually I'm not completely sure that the visitor code generated are
correct in case of implicit structs. In case of normal structs, there's
an if (*obj) { ... } check, but in case of implicit structs it just
visits the fields without checking (which is problematic, since the
default visit_start_implicit_struct is just a no-op, causing segfaults...)

This is needed for my -audiodev option, see v2 patch thread:
http://lists.nongnu.org/archive/html/qemu-devel/2015-06/msg04189.html
And probably this as an example where it's useful:

Check my second link, it contains a good example where it's useful (to
specify input and output audio settings independently, like in.frequency
and out.frequency. Of course we could do like in-frequency and
out-frequency and a bunch of copy paste, but this is a much better way
imho, even if it requires some changes to how existing things work).

Because otherwise you would have to make a version that gets a Netdev
and an other that gets Netlegacy, because the common NetClientOptions is
gone. Unless, of course, I'm overlooking something.
(I've actually tried to simply pass the corect type as arguments, like
net_init_chost_user(const NetdevVhostUserOptions *opts, ...; but then
net_client_init_fun in net.c becomes problematic. Maybe replacing it
with a giant swicth-case would be better?)
