Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2013-12-09audio: Lower default wakeup rate to 100 times / secondHans de Goede
This is more then plenty to keep audio card fifos filles / emptied. This drops host cpu-load for audio playback inside a linux vm from 13% to 9%. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2013-11-07ossaudio: check for oss support in oss_audio_initGerd Hoffmann
Check whenever the device path (/dev/dsp by default) exists and qemu is allowed to access it. Return NULL if it isn't, so ossaudio will not be used on systems wihtout oss support (increasinly common on modern linux systems). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2013-11-07Revert "ossaudio: do not enable by default"Gerd Hoffmann
This reverts commit c905c5012ac0c6fde3b8094d2206a3139deddba2. There is a better fix for the issue at hand. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2013-11-05ossaudio: do not enable by defaultAnthony Liguori
Modern Linux's no longer support /dev/dsp so enabling it by default causes audio failures on newer Linux distros. Signed-off-by: Anthony Liguori <aliguori@amazon.com> Tested-by: Andreas Färber <afaerber@suse.de> Message-id: 1383497154-9271-1-git-send-email-aliguori@amazon.com

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>

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.

2012-12-19janitor: do not rely on indirect inclusions of or from qemu-char.hPaolo Bonzini
Various header files rely on qemu-char.h including qemu-config.h or main-loop.h, but they really do not need qemu-char.h at all (particularly interesting is the case of the block layer!).

2012-08-28audio/winwave: previous audio buffer should be flushedmunkyu.im
Winwave audio backend has problem with pausing and restart audio out. Unlike other backends, Winwave pausing API does not flush audio buffer. As a result, the previous audio data are played in front of user expected sound when user restart audio.

2012-05-18audio: split IN_T into two separate constantsRoger Pau Monne
Split IN_T into BSIZE and ITYPE, to avoid expansion if the OS has defined macros for the intX_t and uintX_t types. The IN_T constant is then defined in mixeng_template.h so it can be used by the functions/macros on this header file. This change has been tested successfully under Debian Linux and NetBSD 6.0BETA.

2011-09-15Replace the VMSTOP macros with a proper state typeLuiz Capitulino
Today, when notifying a VM state change with vm_state_notify(), we pass a VMSTOP macro as the 'reason' argument. This is not ideal because the VMSTOP macros tell why qemu stopped and not exactly what the current VM state is. One example to demonstrate this problem is that vm_start() calls vm_state_notify() with reason=0, which turns out to be VMSTOP_USER. This commit fixes that by replacing the VMSTOP macros with a proper state type called RunState. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
