2019-09-23audio: api for mixeng code free backendsKővágó, Zoltán3-9/+251
This will make it possible to skip mixeng with audio playback and recording, allowing us to free ourselves from the limitations of the current mixeng (stereo, int64 samples only). In this case, HW and SW voices will be essentially the same, for every SW voice we will create a HW voice, since we can no longer mix multiple voices together. Some backends expect us to call a function when we have data ready write()/read() style, while others provide a buffer and expects us to directly write/read it, so for optimal performance audio_pcm_ops provide methods for both cases. Previously backends asked mixeng for more data in run_out/run_it, now instead mixeng or the frontends will call the backends, so that's why two sets of functions required. audio.c contains glue code between the two styles, so backends only ever have to implement one style and frontends are free to call whichever is more convenient for them.

2019-08-28audio: fix invalid malloc size in audio_create_pdosKővágó, Zoltán1-1/+1
The code used sizeof(AudiodevAlsaPerDirectionOptions) instead of the appropriate per direction options for the audio backend. If the size of the actual audiodev's per direction options are larger than alsa's, it could cause a buffer overflow. However, alsa has three fields in per direction options: a string, an uint32 and a bool. Oss has the same fields, coreaudio has a single uint32, paaudio has a string and an uint32, all other backends only use the common options, so currently no per direction options struct should be larger than alsa's.

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.

2019-08-16Include hw/hw.h exactly where neededMarkus Armbruster3-3/+0
In my "build everything" tree, changing hw/hw.h triggers a recompile of some 2600 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). The previous commits have left only the declaration of hw_error() in hw/hw.h. This permits dropping most of its inclusions. Touching it now recompiles less than 200 objects.

2019-08-16Include migration/vmstate.h lessMarkus Armbruster1-0/+1
In my "build everything" tree, changing migration/vmstate.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). hw/hw.h supposedly includes it for convenience. Several other headers include it just to get VMStateDescription. The previous commit made that unnecessary. Include migration/vmstate.h only where it's still needed. Touching it now recompiles only some 1600 objects.

2019-07-03fix microphone lag with PAMartin Schrodt1-1/+1
Several people have reported to have bag microphone lag with the PA backend. While I cannot reproduce the problem here, it seems that their PA somehow decides to buffer the microphone input for way too long, causing this delay. This patch sets an upper limit to the amount of data PA should hold. This fixes the problem reliably on their side, while having no adverse effects on mine.

2019-04-02audio: fix audio timer rate conversion bugVolker Rümelin2-1/+7
Currently the default audio timer frequency is 10000Hz instead of a period of 10000us. Also the audiodev timer-period property gets converted like a frequency. Only handling of the legacy QEMU_AUDIO_TIMER_PERIOD environment variable is correct because it's actually a frequency. With this patch the property timer-period is really a timer period and QEMU_AUDIO_TIMER_PERIOD remains a frequency. Fixes: 71830221fb "-audiodev command line option basic implementation."

2019-03-22trace-events: Shorten file names in commentsMarkus Armbruster1-3/+3
We spell out sub/dir/ in sub/dir/trace-events' comments pointing to source files. That's because when trace-events got split up, the comments were moved verbatim. Delete the sub/dir/ part from these comments. Gets rid of several misspellings.
