2018-03-12audio: add module loading supportGerd Hoffmann1-0/+20
Make audio_driver_lookup() try load the module in case it doesn't find the driver in the registry. Also load all modules for -audio-help, so the help output includes the help text for modular audio drivers.

2018-03-12audio: add driver registryGerd Hoffmann1-26/+37
Add registry for audio drivers, using the existing audio_driver struct. Make all drivers register themself. The old list of audio_driver struct pointers is now a list of audio driver names, specifying the priority (aka probe order) in case no driver is explicitly asked for.

2018-02-06audio: Replace AUDIO_FUNC with __func__Alistair Francis1-20/+20
Apparently we don't use __MSC_VER as a compiler anymore and we always require a C99 compiler (which means we always have __func__) so we don't need a special AUDIO_FUNC macro. We can just replace AUDIO_FUNC with __func__ instead. Checkpatch failures were manually fixed.

2017-03-01audio: make audio poll timer deterministicPavel Dovgalyuk1-1/+1
This patch changes resetting strategy of the audio polling timer. It does not change expiration time if the timer is already set. This patch is needed to make this timer deterministic and to use execution record/replay for audio devices. audio_reset_timer is used in the function audio_vm_change_state_handler. Therefore every time VM is stopped or restarted the timer will be reset to new timeout. Virtual clock does not proceed while VM is stopped. Therefore there is no need in resetting the timeout when VM restarts. v2: updated commit message v3: now using timer_mod_anticipate function (as suggested by Yurii Zubrytskyi) Signed-off-by: Pavel Dovgalyuk <pavel.dovgaluk@ispras.ru> Message-id: 20170214071510.6112.76764.stgit@PASHA-ISP Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2016-08-08audio: clean up before monitor clean upMarc-André Lureau1-8/+18
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.

2016-03-22Replaced get_tick_per_sec() by NANOSECONDS_PER_SECONDRutuja Shah1-2/+1
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.

2016-01-13audio: Clean up inappropriate and unreachable use of hw_error()Markus Armbruster1-9/+2
audio_init() should not use hw_error(), because dumping CPU registers is unhelpful there, and aborting is wrong, because it can be called called from an audio device's realize() method. The two uses of hw_error() come from commit 0d9acba: * When qemu_new_timer() fails. It couldn't fail back then, and it can't fail now. Drop the unreachable error handling. * When no_audio_driver can't be initialized. It couldn't fail back then, and it can't fail now. Replace the error handling by an assertion.

2013-10-23audio: honor QEMU_AUDIO_TIMER_PERIOD instead of waking up every *nano* secondHans de Goede1-1/+2
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.

2011-09-15Replace the VMSTOP macros with a proper state typeLuiz Capitulino1-1/+1
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>

2011-03-21change all other clock references to use nanosecond resolution accessorsPaolo Bonzini1-2/+2
This was done with: sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \ $(git grep -l 'qemu_get_clock\>' ) sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \ $(git grep -l 'qemu_new_timer\>' ) after checking that get_clock and new_timer never occur twice on the same line. There were no missed occurrences; however, even if there had been, they would have been caught by the compiler. There was exactly one false positive in qemu_run_timers: - current_time = qemu_get_clock (clock); + current_time = qemu_get_clock_ns (clock); which is of course not in this patch.

2010-11-09spice: add audioGerd Hoffmann1-0/+3
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.

2010-03-16monitor: Separate "default monitor" and "current monitor" cleanlyMarkus Armbruster1-2/+2
Commits 376253ec..731b0364 introduced global variable cur_mon, which points to the "default monitor" (if any), except during execution of monitor_read() or monitor_control_read() it points to the monitor from which we're reading instead (the "current monitor"). Monitor command handlers run within monitor_read() or monitor_control_read(). Default monitor and current monitor are really separate things, and squashing them together is confusing and error-prone. For instance, usb_host_scan() can run both in "info usbhost" and periodically via usb_host_auto_check(). It prints to cur_mon, which is what we want in the former case: the monitor executing "info usbhost". But since that's the default monitor in the latter case, it periodically spams the default monitor there. A few places use cur_mon to log stuff to the default monitor. If we ever log something while cur_mon points to current monitor instead of default monitor, the log temporarily "jumps" to another monitor. Whether that can or cannot happen isn't always obvious. Maybe logging to the default monitor (which may not even exist) is a bad idea, and we should log to stderr or a logfile instead. But that's outside the scope of this commit. Change cur_mon to point to the current monitor. Create new default_mon to point to the default monitor. Update users of cur_mon accordingly. This fixes the periodical spamming of the default monitor by usb_host_scan(). It also stops "log jumping", should that problem exist.

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.
