2018-03-12audio: add driver registryGerd Hoffmann
Add registry for audio drivers, using the existing audio_driver struct. Make all drivers register themself. The old list of audio_driver struct pointers is now a list of audio driver names, specifying the priority (aka probe order) in case no driver is explicitly asked for.

2018-03-05audio: rename CONFIG_* to CONFIG_AUDIO_*Gerd Hoffmann
This avoids a name clash for CONFIG_SDL, which is used by both sdl video support and sdl audio support. It also more clear that this is a audio driver configuration. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 20180301100547.18962-13-kraxel@redhat.com
2018-02-06audio: Replace AUDIO_FUNC with __func__Alistair Francis
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.

2015-06-15audio: expose drv_opaque to init_out and init_inKővágó, Zoltán
Currently the opaque pointer returned by audio_driver's init is only exposed to the driver's fini, but not to audio_pcm_ops. This way if someone wants to share a variable with the driver and the pcm, he must use global variables. This patch fixes it by adding a third parameter to audio_pcm_op's init_out and init_in.

2013-06-21audio: Replace static functions in header file by macros, remove GCC_ATTRStefan Weil
Using macros instead of static functions for dolog and for ldebug simplifies the code and can also reduce the total code size. GCC_ATTR was only used in audio_int.h, so it is now unused and the definition can be removed from compiler.h.

2012-04-17audio: don't apply volume effect if backend has VOICE_VOLUME_CAPMarc-André Lureau
If the audio backend is capable of volume control, don't apply software volume (mixeng_volume ()), but instead, rely on backend volume control. This will allow guest to have full range volume control. Signed-off-by: Marc-Andr? Lureau <marcandre.lureau@redhat.com> Signed-off-by: malc <av1474@comtv.ru>
2012-04-17audio: add VOICE_VOLUME ctlMarc-André Lureau
Add a new PCM control operation to update the stream volume on the audio backend. The argument given is a SWVoiceOut/SWVoiceIn. v4: - verified other backends didn't fail/assert on this new control they randomly return 0 or -1, but we ignore return value. Signed-off-by: Marc-Andr?

2010-11-09spice: add audioGerd Hoffmann
Add support for the spice audio interface. With this patch applied audio can be forwarded over the network from/to the spice client. Both recording and playback is supported. The driver is first in the driver list, but the can_be_default flag is set only in case spice is active. So if you have the spice protocol enabled the spice audio driver is the default one, otherwise whatever comes first after spice in the list. Overriding the default using QEMU_AUDIO_DRV works in any case.

2010-09-22Move macros GCC_ATTR and GCC_FMT_ATTR to common header fileStefan Weil
By moving the definition of GCC_ATTR and GCC_FMT_ATTR from audio_int.h to qemu-common.h these macros are now generally available for further patches which add the gcc format attribute. Newer gcc versions support format gnu_printf which is better suited for use in QEMU than format printf (QEMU always uses standard format strings (even with mingw32)). V2: Use correct operator '==' (instead of '=') Cc: Blue Swirl <blauwirbel@gmail.com> Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-09-12Fix sys-queue.h conflict for goodBlue Swirl
Problem: Our file sys-queue.h is a copy of the BSD file, but there are some additions and it's not entirely compatible. Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896, f40d753718c72693c5f520f0d9899f6e50395e94, 96555a96d724016e13190b28cffa3bc929ac60dc and 3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file. Revert the previous hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
