2023-10-08audio: reintroduce default audio backend for VNCPaolo Bonzini
Make VNC use the default backend again if one is defined. The recently introduced support for disabling the VNC audio extension is still used, in case no default backend exists. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2023-10-08audio: extract audio_define_defaultPaolo Bonzini
It will be used soon to define a default audio device from the command line. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2023-10-08audio: disable default backends if -audio/-audiodev is usedPaolo Bonzini
Match what is done for other options, for example -monitor, and also the behavior of QEMU 8.1 (see the "legacy_config" variable). Require the user to specify a backend if one is specified on the command line. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2023-10-03audio: propagate Error * out of audio_initMartin Kletzander
Starting from audio_driver_init, propagate errors via Error ** so that audio_init_audiodevs can simply pass &error_fatal, and AUD_register_card can signal faiure.

2023-10-03audio: remove QEMU_AUDIO_* and -audio-help supportPaolo Bonzini
These have been deprecated for a long time, and the introduction of -audio in 7.1.0 has cemented the new way of specifying an audio backend's parameters. However, there is still a need for simple configuration of the audio backend in the desktop case; therefore, if no audiodev is passed to audio_init(), go through a bunch of simple Audiodev* structures and pick the first that can be initialized successfully. The only QEMU_AUDIO_* option that is left in, waiting for a better idea, is QEMU_AUDIO_DRV=none which is used by qtest. Remove all the parsing code, including the concept of "can_be_default" audio drivers: now that audio_prio_list[] is only used in a single place, wav can be excluded directly in that function.

2022-09-02audio: exit(1) if audio backend failed to be found or initializedMarc-André Lureau
If you specify a known backend but it isn't compiled in, or failed to initialize, you get a simple warning and the "none" backend as a fallback, and QEMU runs happily: $ qemu-system-x86_64 -audiodev id=audio,driver=dsound audio: Unknown audio driver `dsound' audio: warning: Using timer based audio emulation ... Instead, QEMU should fail to start: $ qemu-system-x86_64 -audiodev id=audio,driver=dsound audio: Unknown audio driver `dsound' $ Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1983493 Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Volker Rümelin <vr_qemu@t-online.de> Message-Id: <20220822131021.975656-1-marcandre.lureau@redhat.com>
2022-05-14introduce -audio as a replacement for -soundhwPaolo Bonzini
-audio is used like "-audio pa,model=sb16". It is almost as simple as -soundhw, but it reuses the -audiodev parsing machinery and attaches an audiodev to the newly-created device. The main 'feature' is that it knows about adding the codec device for model=intel-hda, and adding the audiodev to the codec device. In the future, it could be extended to support default models or builtin devices, just like -nic, or even a default backend. For now, keep it simple.

2022-04-06Replace config-time define HOST_WORDS_BIGENDIANMarc-André Lureau
Replace a config-time define with a compile time condition define (compatible with clang and gcc) that must be declared prior to its usage. This avoids having a global configure time define, but also prevents from bad usage, if the config header wasn't included before. This can help to make some code independent from qemu too. gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.

2019-03-11audio: -audiodev command line option basic implementationKővágó, Zoltán
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.

2016-08-08audio: clean up before monitor clean upMarc-André Lureau
Since aa5cb7f5e, the chardevs are being cleaned up when leaving qemu, before the atexit() handlers. audio_cleanup() may use the monitor to notify of changes. For compatibility reasons, let's clean up audio before the monitor so it keeps emitting monitor events. The audio_atexit() function is made idempotent (so it can be called multiple times), and renamed to audio_cleanup(). Since coreaudio backend is using a 'isAtexit' code path, change it to check audio_is_cleaning_up() instead, so the path is taken during normal exit.

2010-10-03Replace most gcc format attributes by macro GCC_FMT_ATTR (format checking)Stefan Weil
Since version 4.4.x, gcc supports additional format attributes. __attribute__ ((format (gnu_printf, 1, 2))) should be used instead of __attribute__ ((format (printf, 1, 2)) because QEMU always uses standard format strings (even with mingw32). The patch replaces format attribute printf / __printf__ by macro GCC_FMT_ATTR which uses gnu_printf if supported. It also removes an #ifdef __GNUC__ (not needed any longer).

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>
