dead stores in msxml3
by ricardo filipe 18 Nov '08

18 Nov '08

hi leslie. i'm tracking some dead stores with Clang and there are some in dlls/msxml3/saxreader.c i'm hoping you can tell me if the stores are to be removed for performance or if they should be checked in each iteration for correctness: file dlls/msxml3/saxreader.c lines: 1163 1166 1213 1216 regards, ricardo _________________________________________________________________ Confira vídeos com notícias do NY Times, gols direto do Lance, videocassetadas e muito mais no MSN Video! http://video.msn.com/?mkt=pt-br

You should load it directly into the destination buffer. -- Alexandre Julliard julliard(a)winehq.org

Another source of hardware statistics!

Unity3d is a game engine for casual gaming (not hardcore gaming). They have some good data on their user base's hardware at http://unity3d.com/webplayer/hwstats e.g. their breakdown of video cards for this quarter is at http://unity3d.com/webplayer/hwstats/pages/web-2008Q4-gfxcard.html Their top 3 graphics cards are Intel 945 (GMA 950) 13.3% Nvidia GeForce 6100 7.5% ATI Radeon X300/X550/Xpress200/1100 6.9% And believe it or not, 8% of their users still only have 256MB of RAM... - Dan

I had the same fix queued up in my tree. However, your changelog message needs some work. The bug isn't specific to Vista x86, but is probably specific to the IDL file you are compiling. -- Rob Shearman

NT driver address space
by Alexander Morozov 18 Nov '08

18 Nov '08

Hi, Under Wine NT drivers are running in user address space. Some drivers do not work correctly because of this. For example Guardant USB token driver crashes when loading but this problem can be fixed with such patch (really I tested with our wine fork): diff --git a/dlls/ntdll/virtual.c b/dlls/ntdll/virtual.c index 78e38dc..f607f22 100644 --- a/dlls/ntdll/virtual.c +++ b/dlls/ntdll/virtual.c @@ -904,6 +904,7 @@ static NTSTATUS map_image( HANDLE hmapping, int fd, char *base, SIZE_T total_siz server_enter_uninterrupted_section( &csVirtual, &sigset ); + if (0x10000 == base) base = 0x81000000; if (base >= (char *)0x110000) /* make sure the DOS area remains free */ status = map_view( &view, base, total_size, mask, FALSE, VPROT_COMMITTED | VPROT_READ | VPROT_EXEC | VPROT_WRITECOPY | VPROT_IMAGE ); diff --git a/libs/wine/mmap.c b/libs/wine/mmap.c index ff117cc..4c18683 100644 --- a/libs/wine/mmap.c +++ b/libs/wine/mmap.c @@ -346,7 +346,7 @@ void mmap_init(void) #if defined(__i386__) && !defined(__FreeBSD__) && !defined(__FreeBSD_kernel__) /* commented out until FreeBSD gets fixed */ char stack; char * const stack_ptr = &stack; - char *user_space_limit = (char *)0x7ffe0000; + char *user_space_limit = (char *)0xaffe0000; reserve_malloc_space( 8 * 1024 * 1024 ); I see two ways of fixing this. 1. Modify wine to run winedevice.exe in kernel address space (> 0x80000000) by checking name of executable. 2. Modify ExAllocatePool and some other functions to use kernel address space, modify functions which is used by drivers (ntoskrnl.exe exports etc.) to use only this memory allocation functions, modify winedevice.exe to load driver and create stack in kernel address space. What is better decision? Thanks, Alexander Morozov

Re: Patch for [Bug 16087] wine spews innumerable "Unable to check compatibility for Format..." errors in some games

That would seem better to me than prefiltering the parameters > It does, it returns FALSE for "unsupported" formats. The only thing the patch fixes is the FIXME & ERR output. I think there are places where we'd like getColorBits() to work properly for float formats though.

We should probably fix the format table to use a shift and a bitcount.
