Alistair Francis 470bcabd8f audio: Replace AUDIO_FUNC with __func__
Apparently we don't use __MSC_VER as a compiler anymore and we always
require a C99 compiler (which means we always have __func__) so we don't
need a special AUDIO_FUNC macro. We can just replace AUDIO_FUNC with
__func__ instead.

Checkpatch failures were manually fixed.

Eric Blake 2562755ee7 maint: Fix macros with broken 'do/while(0); ' usage
The point of writing a macro embedded in a 'do { ... } while (0)'
loop (particularly if the macro has multiple statements or would
otherwise end with an 'if' statement) is so that the macro can be
used as a drop-in statement with the caller supplying the
trailing ';'.  Although our coding style frowns on brace-less 'if':
  if (cond)
    statement;
  else
    something else;
that is the classic case where failure to use do/while(0) wrapping
would cause the 'else' to pair with any embedded 'if' in the macro
rather than the intended outer 'if'.  But conversely, if the macro
includes an embedded ';', then the same brace-less coding style
would now have two statements, making the 'else' a syntax error
rather than pairing with the outer 'if'.  Thus, even though our
coding style with required braces is not impacted, ending a macro
with ';' makes our code harder to port to projects that use
brace-less styles.

The change should have no semantic impact.  I was not able to
fully compile-test all of the changes (as some of them are
examples of the ugly bit-rotting debug print statements that are
completely elided by default, and I didn't want to recompile
with the necessary -D witnesses - cleaning those up is left as a
bite-sized task for another day); I did, however, audit that for
all files touched, all callers of the changed macros DID supply
a trailing ';' at the callsite, and did not appear to be used
as part of a brace-less conditional.

Found mechanically via: $ git grep -B1 'while (0);' | grep -A1 \\\\

Vladimir Sementsov-Ogievskiy db73ee4bc8 trace-events: fix code style: %# -> 0x%

This patch is created by the following:

check that we have a problem
> find . -name trace-events | xargs grep '%#' | wc -l
56

check that there are no cases with additional printf flags before '#'
> find . -name trace-events | xargs grep "%[-+ 0'I]+#" | wc -l
0

check that there are no wrong usage of '#' and '0x' together
> find . -name trace-events | xargs grep '0x%#' | wc -l
0

fix the problem
> find . -name trace-events | xargs sed -i 's/%#/0x%/g'

[Eric Blake noted that xargs grep '%[-+ 0'I]+#' should be xargs grep
"%[-+ 0'I]+#" instead so the shell quoting is correct.

Thomas Huth bcf19777df audio/sdlaudio: Allow audio playback with SDL2
When compiling with SDL2, the semaphore trick used in sdlaudio.c
does not work - QEMU locks up completely in this case. To avoid
the hang and get at least some audio playback up and running (it's
a little bit crackling, but better than nothing), we can use the
SDL locking functions SDL_LockAudio() and SDL_UnlockAudio() to sync
with the sound playback thread instead.

Pavel Dovgalyuk 1ffc266539 audio: make audio poll timer deterministic
This patch changes resetting strategy of the audio polling timer.
It does not change expiration time if the timer is already set.
This patch is needed to make this timer deterministic and to use execution
record/replay for audio devices.

audio_reset_timer is used in the function audio_vm_change_state_handler.
Therefore every time VM is stopped or restarted the timer will be reset
to new timeout. Virtual clock does not proceed while VM is stopped.
Therefore there is no need in resetting the timeout when VM restarts.

Marc-André Lureau a384c205ac audio: clean up before monitor clean up
Since aa5cb7f5e, the chardevs are being cleaned up when leaving qemu,
before the atexit() handlers. audio_cleanup() may use the monitor to
notify of changes. For compatibility reasons, let's clean up audio
before the monitor so it keeps emitting monitor events.

The audio_atexit() function is made idempotent (so it can be called
multiple times), and renamed to audio_cleanup(). Since coreaudio
backend is using a 'isAtexit' code path, change it to check
audio_is_cleaning_up() instead, so the path is taken during normal
exit.

Since pulseaudio 1.0 it's possible to set the individual stream volume
rather than setting the device volume. With this, setting hardware mixer
of a emulated sound card doesn't mess up the volume configuration of the

For example,

    timer_mod(fdctrl->result_timer,
	      qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50));

NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns

Markus Armbruster 7e274652e4 audio: Clean up inappropriate and unreachable use of hw_error()
audio_init() should not use hw_error(), because dumping CPU registers
is unhelpful there, and aborting is wrong, because it can be called
called from an audio device's realize() method.

The two uses of hw_error() come from commit 0d9acba:

* When qemu_new_timer() fails.  It couldn't fail back then, and it
  can't fail now.  Drop the unreachable error handling.

* When no_audio_driver can't be initialized.  It couldn't fail back
  then, and it can't fail now.  Replace the error handling by an
  assertion.

Peter Maydell 2f79a18fdd audio/coreaudio.c: Avoid deprecated AudioDeviceAdd/RemoveIOProc APIs
The AudioDeviceAddIOProc() and AudioDeviceRemoveIOProc() functions were
deprecated in OSX 10.5. Since we don't support any earlier versions of
OSX, we can simply replace them with the new APIs
AudioDeviceCreateIOProcID() and AudioDeviceRemoveIOProcID().

of the deprecated AudioDeviceGetProperty() and AudioDeviceSetProperty()
functions when possible.

Peter Maydell 95a860f62e audio/coreaudio.c: Factor out uses of AudioDeviceGet/SetProperty
The CoreAudio APIs AudioDeviceGetProperty and AudioDeviceSetProperty are
deprecated from OSX 10.6, so factor out our calls to them so we can
provide versions which use the replacement APIs on OSX newer than 10.5.

provide an equivalent with the new APIs when they exist.

Kővágó, Zoltán 6dd35fd81e dsoundaudio: remove primary buffer
Enabling this option just creates a playback buffer with the specified settings,
and then ignores it. It's probably some outdated hack to set audio formats on
windows. (The first created stream dictates all other streams settings, at least
on some Windows versions). Setting DAC_FIXED_SETTINGS should have the same
effect as setting (the now removed) primary buffer.

Kővágó, Zoltán 2762955f72 dsoundaudio: remove *_retries kludges
According to MSDN this may happen when the window is not in the foreground, but
the default is 1 since a long time (which means no retries), so it should be ok.
I've found no problems during testing it on Windows 7 and wine, so this was
probably only the case with some old Windows versions.
