docs: fix references to docs/devel/tracing.rst Commit e50caf4a5c ("tracing: convert documentation to rST") converted docs/devel/tracing.txt to docs/devel/tracing.rst. We still have several references to the old file, so let's fix them with the following command: sed -i s/tracing.txt/tracing.rst/ $(git grep -l docs/devel/tracing.txt) Signed-off-by: Stefano Garzarella <sgarzare@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20210517151702.109066-2-sgarzare@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>

trace-events: Shorten file names in comments 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.

audio/hda: tweak timer adjust logic We have some jitter in the audio timer call frequency and buffer sizes. So it is rather pointless trying to be very exact, effect is a constant up+down adjustment.

hw/audio/via-ac97: Basic implementation of audio playback Add basic implementation of the AC'97 sound part used in VIA south bridge chips. Not all features of the device is emulated, only one playback channel is supported for now but this is enough to get sound output from some guests using this device on pegasos2.

audio: add Apple Sound Chip (ASC) emulation The Apple Sound Chip was primarily used by the Macintosh II to generate sound in hardware which was previously handled by the toolbox ROM with software interrupts. Implement both the standard ASC and also the enhanced ASC (EASC) functionality which is used in the Quadra 800. Note that whilst real ASC hardware uses AUDIO_FORMAT_S8, this implementation uses AUDIO_FORMAT_U8 instead because AUDIO_FORMAT_S8 is rarely used and not supported by some audio backends like PulseAudio and DirectSound when played directly with -audiodev out.mixing-engine=off.
