v3 cover -audiodev option

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

PATCH v3 1/8 qapi: support implicit structs in OptsVisitor

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

Why drop the assertion?

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?)

PATCH v3 4/8 qapi: qapi for audio backends

In reply to Kővágó, Zoltán

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.

PATCH v3 5/8 qapi: support nested structs in OptsVisitor

In reply to Kővágó, Zoltán

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' orout.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.

---

Change from v2:
* only fully qualified paths are allowed

Re: [Qemu-devel] [PATCH v3 5/8] qapi: support nested structs in OptsVisitor

Quoted 433 lines · Zoltán

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' orout.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.

---

Change from v2:
* only fully qualified paths are allowed

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 :))

Re: [Qemu-devel] [PATCH v3 5/8] qapi: support nested structs in OptsVisitor

Quoted 433 lines

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' orout.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.

---

Change from v2:
* only fully qualified paths are allowed

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.

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...)

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?

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).

(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".)

Quoted 6 lines

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.)

All right, no problem.

PATCH v3 6/8 opts: produce valid command line in qemu_opts_print

In reply to Kővágó, Zoltán

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

---

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

PATCH v3 7/8 audio: use qapi AudioFormat instead of audfmt_e

In reply to Kővágó, Zoltán

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.

---

Changes from v2:
* replaced case AUDIO_FORMAT_MAX with default

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
