mmdevapi: Avoid lock contention after SetEvent.
by Joerg-Cyril.Hoehle＠t-systems.com Dec. 21, 2012

Dec. 21, 2012

Hi, what's up with this patch? I wrote: >SetEvent is one of those calls with a high probability that the >Linux scheduler will switch to another thread, e.g. the one receiving >the event. As the critical section is still hold, it'll prevent the >receiver from invoking mmdevapi, e.g. GetCurrentPadding, without two >more thread switches (forth and back). We don't need that. Now that This->event is constant between IAC_Start and IAC_Release, thanks to my "SetEventHandle is allowed once only" patch, it's safe to move SetEvent(This->event) outside of the CS. Unlike the rejected patch about a CreateTimerQueue race condition internal to Wine (and only relevant in lock-less mode), this one is between the driver and the client app that blocks when calling e.g. GetCurrentPadding, what almost all apps will do, including our DSound http://source.winehq.org/source/dlls/dsound/mixer.c#L679 Regards, Jörg Höhle

winepulse test data review
by Joerg-Cyril.Hoehle＠t-systems.com Dec. 20, 2012

Dec. 20, 2012

Hi, Maarten Lankhorst wrote: >Actually in winepulse, sleep / 12000 (8 ms I guess?) ms would work, no sleep at all works too, Yes, I wanted to go no further than 8ms below the 10ms period limit. > it was just the mixing of various levels of sleep that was failing. Not sure why though, > might be something about the scheduling throwing it off. There's a perfectly simple explanation of this that applies to both winepulse and winecoreaudio. It goes as follows. IOW, there's a bug in winecoreaudio. It may explain why the test stutters on my MacOS 10.5.8 machine, regardless of how accurate or "improved" GetPosition is. winecoreaudio's IAC_ReleaseBuffer sends packets off as soon as it receives data, unlike winealsa/wineoss. Consider the sleep sequence 0 5 8 0 5 ms... + The transition 8 -> 0ms sleep is fine, as data is sent 2ms after the prior packet - The transition 0 -> 5 is most problematic, as it means that 2 ReleaseBuffer will be 15ms apart, even though only 10ms of data was sent. I believe winepulse is affected by this too, like winecoreaudio. The stable sequences "always 0" or "always 8ms sleep" are paced regularly, so underruns are avoided as long as the OS schedules the threads soon enough. Winealsa and wineOSS are not affected, as they write data on the 10ms period boundaries, -- like native presumably does. winecoreaudio solution paths: - write packets on period tick, not at release time - or add silence lead-in - or delay first packet until period tick only (if small) - or ... I think it should be possible to produce reliable continuous sound in winepulse and winecoreaudio yet maintain their current "send packet" codebase instead of transitioning to a separate buffer that winealsa and wineoss use.
