Hi, While running your changed tests on Windows, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check? Full results can be found at http://testbot.winehq.org/JobDetails.pl?Key=23542 Your paranoid android. === W7PRO (32 bit http) === http.c:3337: Test failed: HttpSendRequest failed: 12002

Re: dsound: change mix rate of primary buffer

That does always mix to float, and there isn't a way to change it right now. What are you planning to use this for? We could support different mix buffer formats, but I'm not sure this use case is worth the effort. Andrew

Clang static analyzer results / wine-1.5.19-186-g1cd0c4a
by Austin English 18 Dec '12

Now that http://source.winehq.org/git/wine.git/commitdiff/4adfb787f4e8c36a37ce1d53a7… is in (and clang has improved), several wine/clang bugs are fixed. For those curious, there is one remaining test failure on my machine, with clang instead of gcc: http://bugs.winehq.org/show_bug.cgi?id=25828 The static analyzer results were made with: llvm: git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170295 91177308-0d34-0410-b5e6-96231b3b80d8 clang: git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170294 91177308-0d34-0410-b5e6-96231b3b80d8 wine: wine-1.5.19-186-g1cd0c4a ./configure --disable-tests was used to reduce noise austin@debian-home:~$ du -h wine-1.5.19-186-g1cd0c4a.tar.bz2 39M wine-1.5.19-186-g1cd0c4a.tar.bz2 austin@debian-home:~$ sha1sum wine-1.5.19-186-g1cd0c4a.tar.bz2 bf86469ab3929faf996b76d4a8e533edcf24fd29 wine-1.5.19-186-g1cd0c4a.tar.bz2 Available at http://www.mediafire.com/?0gioifbgw363az3 -- -Austin

winealsa: Separate read and write pointers.

That requires agreement on the lock-less protocol. Basis: atomic 32bit updates. Do we want distinguished alignment declarations for e.g. This->held_frames? Write: InterlockedExchange/Increment/etc. is clear Read: Open for discussion Basically, all I need is a snapshot of a 32bit entity, i.e. an atomic read. The code doesn't bother whether that value is stale or not. It works in either case. All that is required is that it's updated some time eventually (i.e. not running off local cache for hours). Back in the old days, people used foo = (volatile X) bar; or even volatile X bar; ... foo=bar; Such code has been present e.g. in mciseq for the last 10 years. Currently, this has my preference for Intel: foo = bar; // e.g. held = This->held_frames; __asm__ __volatile__("":::"memory"); /* compiler barrier is enough for x86 */ I wouldn't be opposed to held = (volatile DWORD) This->held_frames; Purists spit at volatile for threading, but that's what has been used for decades and continues to be used (just google some random threading app...) I've also suggested InterlockedExchange(&held, This->held_frames) but that's just wasting a read of the obsolete value of held. So why use that form? Do we need to care for anything else than Intel? One may envision other approaches, e.g. a second critical section for the callback and Start/Stop only. But This->held_frames is updated within IAC_Get/ReleaseBuffer, so that doesn't solve the issue. POSIX purists would say that a protocol is needed between the two communicating threads (the Get/Release one and the cb, not the Start/Stop thread). But I don't care about POSIX requirements imposed by weird 8/16/24/32/40/64 bit HW and strange non-UNIX systems when the target is Wine-Is-Not-an-Emulator. Regards, Jörg Höhle

I tested it against my usual set of applications both with and without PulseAudio. This patch seems fine to me. I'll take a look at your lockless patch on bug 29531, and maybe we can get that into Wine after the next release? Andrew

dsound: change mix rate of primary buffer
by sebastien chev 18 Dec '12

18 Dec '12

It seems that no matter what the Windows side program choose for DirectSoundCreate, the DSound subsystem initialize itself with the higher spec sound available (for example 48Khz Float32, or 48kHz Int16 if no Float32 available). While not a big deal on current linux PC, using this on ARM device kill performance. A DirectSound subsystem for ARM, with Integer only for the mixbuffer (as most ARM still use softfloat) and 22kHz should be less taxing for performances.

This doesn't make sense, there's a critical section. -- Alexandre Julliard julliard(a)winehq.org
