2012-12-19misc: move include files to include/qemu/Paolo Bonzini1-1/+1
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-12-19janitor: do not include qemu-char everywherePaolo Bonzini1-1/+0
Touching char/char.h basically causes the whole of QEMU to be rebuilt. Avoid this, it is usually unnecessary. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-12-19janitor: do not rely on indirect inclusions of or from qemu-char.hPaolo Bonzini1-0/+1
Various header files rely on qemu-char.h including qemu-config.h or main-loop.h, but they really do not need qemu-char.h at all (particularly interesting is the case of the block layer!). Clean this up, and also add missing inclusions of qemu-char.h itself. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2011-01-12audio: split sample conversion and volume mixingMichael Walle1-1/+1
Refactor the volume mixing, so it can be reused for capturing devices. Additionally, it removes superfluous multiplications with the nominal volume within the hardware voice code path. Signed-off-by: Michael Walle <michael@walle.cc> Signed-off-by: malc <av1474@comtv.ru>

2010-10-18issue snd_pcm_start() when capturing audioJindrich Makovicka1-6/+17
snd_pcm_start() starts the capture process and ensures that the events are delivered to the poll handler. Without the call, capture can be started only when there is simultaneous playback running. Signed-off-by: Jindrich Makovicka <makovick@gmail.com> Signed-off-by: malc <av1474@comtv.ru>
2010-10-18fix 100% CPU load when idle with ALSAJindrich Makovicka1-0/+4
Playback control function did not disable polling when playback stops. Caused busy spinning of the main loop due to unprocessed events. Signed-off-by: Jindrich Makovicka <makovick@gmail.com> Signed-off-by: malc <av1474@comtv.ru>
2010-04-21audio/alsa: Avoid snd_pcm_format_t vs audfmt_e mixupmalc1-5/+6
Spotted by Serge Ziryukin and based on his patch, thanks. Signed-off-by: malc <av1474@comtv.ru>

2010-02-28audio/alsa: Spelling typo (paramters)Vagrant Cascadian1-1/+1
Trivial patch to fix the spelling of "parameters". Signed-off-by: malc <av1474@comtv.ru>
2009-10-03oss/alsa: Do not invoke UB described in 7.15.1.1 (this time for ADC)malc1-12/+15

2009-10-02alsa: Change default buffer/period sizemalc1-1/+2
Increase buffer size but do not rely on ALSA picking up default period size. Signed-off-by: malc <av1474@comtv.ru>
2009-10-02oss/alsa: Do not invoke UB described in 7.15.1.1malc1-11/+14
Additional argument (whether to try poll mode) is only passed with VOICE_ENABLE command. Thanks to Markus Armbruster for noticing the potential breakage.
2009-09-18audio: internal API changemalc1-7/+2
pcm_ops.run_out now takes number of live samples (which will be always greater than zero) as a second argument, every driver was calling audio_pcm_hw_get_live_out anyway with exception of fmod which used audio_pcm_hw_get_live_out2 for no good reason. Signed-off-by: malc <av1474@comtv.ru>

2009-07-30alsa: add host suspend/resume supportBjørn Mork1-2/+47
Both input and output streams may be in SND_PCM_STATE_SUSPENDED after the host is suspended and resumed, meaning "Hardware is suspended". snd_pcm_readi() and snd_pcm_writei() will return -ESTRPIPE if called while the stream is in this state. Call snd_pcm_resume() to enable audio output and capture after host resume. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: malc <av1474@comtv.ru>
2009-07-17Ignore -Waddress for alsaaudio.cmalc1-0/+4
/usr/include/alsa/pcm.h contains: #define snd_pcm_sw_params_alloca(ptr) do { assert(ptr); *ptr = (snd_pcm_sw_params_t *) alloca(snd_pcm_sw_params_sizeof()); memset(*ptr, 0, snd_pcm_sw_params_sizeof()); } while (0) The assert generates: "error: the address of 'sw_params' will always evaluate as 'true'" which combined with -Werror prevents alsaaudio.o from being built with certain versions of GCC.
