* audio: remove qemu_spice_audio_init()Gerd Hoffmann2020-09-231-5/+0Star
| | | | | | | | | | Handle the spice special case in audio_init instead. With the qemu_spice_audio_init() symbol dependency being gone we can build spiceaudio as module. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 20200916084117.21828-2-kraxel@redhat.com
* audio/spiceaudio: always rate limit playback streamVolker Rümelin2020-09-231-6/+4Star
| | | | | | | | | | | | | The playback rate with the spiceaudio backend is currently too fast if there's no spice client connected or the spice client can't play audio. Rate limit the audio playback stream in all cases. To calculate the rate correctly the limiter has to know the maximum buffer size.

* audio: handle buf == NULL in put_buffer_out()Volker Rümelin2020-09-231-5/+8
| | | | | | | | | | | | | | | With the next patch all audio backends put_buffer_out() functions have to handle the buf == NULL case, provided the get_buffer_out() function may return buf = NULL and size > 0. It turns out that all audio backends get_buffer_out() functions either can't return buf = NULL or return buf = NULL and size = 0 at the same time. The only exception is the spiceaudio backend where size may be uninitialized.

* audio: replace shift in audio_pcm_info with bytes_per_frameKővágó, Zoltán2019-10-181-1/+2
| | | | | | | | | | | The bit shifting trick worked because the number of bytes per frame was always a power-of-two (since QEMU only supports mono, stereo and 8, 16 and 32 bit samples). But if we want to add support for surround sound, this no longer holds true.

* audio: common rate control code for timer based outputsKővágó, Zoltán2019-09-231-43/+8Star
| | | | | | | | | | | This commit removes the ad-hoc rate-limiting code from noaudio and wavaudio, and replaces them with a (slightly modified) code from spiceaudio. This way multiple write calls (for example when the circular buffer wraps around) do not cause problems.

* Include hw/hw.h exactly where neededMarkus Armbruster2019-08-161-1/+0Star
| | | | | | | | | | | | | | | | 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.

* audio: -audiodev command line option basic implementationKővágó, Zoltán2019-03-111-1/+1
| | | | | | | | | | | | | | | | | | | | Audio drivers now get an Audiodev * as config paramters, instead of the global audio_option structs. There is some code in audio/audio_legacy.c that converts the old environment variables to audiodev options (this way backends do not have to worry about legacy options). It also contains a replacement of -audio-help, which prints out the equivalent -audiodev based config of the currently specified environment variables. Note that backends are not updated and still rely on environment variables. Also note that (due to moving try-poll from global to backend specific option) currently ALSA and OSS will always try poll mode, regardless of environment variables or -audiodev options.

* audio: use qapi AudioFormat instead of audfmt_eKővágó, Zoltán2019-03-111-2/+2
| | | | | | | | | | | | | | I had to include an enum for audio sampling formats into qapi, but that meant duplicating the audfmt_e enum. This patch replaces audfmt_e and associated values with the qapi generated AudioFormat enum. This patch is mostly a search-and-replace, except for switches where the qapi generated AUDIO_FORMAT_MAX caused problems.

* Replaced get_tick_per_sec() by NANOSECONDS_PER_SECONDRutuja Shah2016-03-221-2/+2
| | | | | | | | | | | | | | | | | | This patch replaces get_ticks_per_sec() calls with the macro NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec() is then removed. This replacement improves the readability and understandability of code. 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 matches the unit of the expression on the right side of the plus.

| | | | | | | | | | | 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.

* spice: add audioGerd Hoffmann2010-11-091-0/+327
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.
