2014-12-22audio: Don't free hw resources until after hw backend is stoppedPeter Maydell
When stopping an audio voice, call the audio backend's fini method before calling audio_pcm_hw_free_resources_ rather than afterwards. This allows backends which use helper threads (like pulseaudio) to terminate those threads before the conv_buf or mix_buf are freed and avoids race conditions where the helper may access a NULL pointer or freed memory.

2014-05-14savevm: Remove all the unneeded version_minimum_id_old (rest)Juan Quintela
After previous Peter patch, they are redundant. This way we don't assign them except when needed. Once there, there were lots of case where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (appart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.

2014-05-08build: convert some obj-specific CFLAGS to use new foo.o-cflags syntaxMichael Tokarev

2013-10-23audio: honor QEMU_AUDIO_TIMER_PERIOD instead of waking up every *nano* secondHans de Goede
Now that we no longer have MIN_REARM_TIMER_NS a bug in the audio subsys has clearly shown it self by trying to make a timer fire every nano second. Note we have a similar problem in 1.6, 1.5 and older but there MIN_REARM_TIMER_NS limits the wakeups caused by audio being active to 4000 times / second. This still causes a host cpu load of 50 % for simply playing audio, where as with this patch git master is at 13%, so we should backport this to 1.5 and 1.6 too. Note this will not apply to 1.5 and 1.6 as is. Cc: qemu-stable@nongnu.org Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
