2021-01-15dsoundaudio: replace GetForegroundWindow()Volker Rümelin
GetForegroundWindow() doesn't necessarily return the own window handle. It just returns a handle to the currently active window and can even return NULL. At the time dsound_open() gets called the active window is most likely the shell window and not the QEMU window. Replace GetForegroundWindow() with GetDesktopWindow() which always returns a valid window handle, and at the same time replace the DirectSound buffer flag DSBCAPS_STICKYFOCUS with DSBCAPS_GLOBALFOCUS where Windows only expects a valid window handle for DirectSound function SetCooperativeLevel(). The Microsoft online docs for IDirectSound::SetCooperativeLevel recommend this in the remarks. This fixes a bug where you can't hear sound from the guest. To reproduce start qemu with -machine pcspk-audiodev=audio0 -device intel-hda -device hda-duplex,audiodev=audio0 -audiodev dsound,id=audio0,out.mixing-engine=off from a shell and start audio playback with the hda device in the guest. The guest will be silent. To hear guest audio you have to activate the shell window once.

2021-01-15paaudio: send recorded data in smaller chunksVolker Rümelin
Tell PulseAudio to send recorded audio data in smaller chunks than timer_period, so there's a good chance that qemu can read recorded audio data every time it looks for new data. PulseAudio tries to send buffer updates at a fragsize / 2 rate. With fragsize = timer_period / 2 * 3 the update rate is 75% of timer_period. The lower limit for the recording buffer size maxlength is fragsize * 2.

2021-01-15paaudio: limit minreq to 75% of audio timer_rateVolker Rümelin
Currently with the playback buffer attribute minreq = -1 and flag PA_STREAM_EARLY_REQUESTS PulseAudio uses minreq = tlength / 4. To improve audio playback with larger PulseAudio server side buffers, limit minreq to a maximum of 75% of audio timer_rate. That way there is a good chance qemu receives a stream buffer size update before it tries to write data to the playback stream.

2021-01-15paaudio: avoid to clip samples multiple timesVolker Rümelin
The pulseaudio backend currently converts, clips and copies audio playback samples in the mixing-engine sample buffer multiple times. In qpa_get_buffer_out() the function pa_stream_begin_write() returns a rather large buffer and this allows audio_pcm_hw_run_out() in audio/audio.c to copy all samples in the mixing-engine buffer to the pulse audio buffer. Immediately after copying, qpa_write() notices with a call to pa_stream_writable_size() that pulse audio only needs a smaller part of the copied samples and ignores the rest. This copy and ignore process happens several times for each audio sample. To fix this behaviour, call pa_stream_writable_size() in qpa_get_buffer_out() to limit the number of samples audio_pcm_hw_run_out() will convert. With this change the pulseaudio pcm_ops functions put_buffer_out and write are no longer identical and a separate qpa_put_buffer_out is needed.

Always stop audio playback and remove the playback callback when QEMU exits.

2020-10-09monitor: Use getter/setter functions for cur_monKevin Wolf
cur_mon really needs to be coroutine-local as soon as we move monitor command handlers to coroutines and let them yield. As a first step, just remove all direct accesses to cur_mon so that we can implement this in the getter function later.

2020-09-23qemu/atomic.h: rename atomic_ to qatomic_Stefan Hajnoczi
clang's C11 atomic_fetch_*() functions only take a C11 atomic type pointer argument. QEMU uses direct types (int, etc) and this causes a compiler error when a QEMU code calls these functions in a source file that also included <stdatomic.h> via a system header file: $ CC=clang CXX=clang++ ./configure ... && make ../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid) Avoid using atomic_*() names in QEMU's atomic.h since that namespace is used by <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h and <stdatomic.h> can co-exist. I checked /usr/include on my machine and searched GitHub for existing "qatomic_" users but there seem to be none. This patch was generated using: $ git grep -h -o '\<atomic\(64\)\?_[a-z0-9_]\+' include/qemu/atomic.h | \ sort -u >/tmp/changed_identifiers $ for identifier in $(</tmp/changed_identifiers); do sed -i "s%\<$identifier\>%q$identifier%g" \ $(git grep -I -l "\<$identifier\>") done I manually fixed line-wrap issues and misaligned rST tables.
