[Bug 27885] New: Starcraft 2 + Mesa 7.12-devel Gallium 4 on AMD REDWOOD: No Textures in Game

http://bugs.winehq.org/show_bug.cgi?id=27885

Summary: Starcraft 2 + Mesa 7.12-devel Gallium 4 on AMD
                    REDWOOD: No Textures in Game
           Product: Wine
           Version: 1.3.24
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Running Starcraft 2 with current git wine and current git mesa on Ubuntu 11.04
works except for textures. They are not drawn.

It looks like a problem in the association of DXT5 formal surfaces. For some
reason wine does not set the "internal formal", "gl format" and "gl type" to
correct values, but leaves them as 0.

Here are the relevant log traces of mesa vs fglrx:
mesa:
trace:d3d_surface:surface_allocate_surface (0x20c18880) : Creating surface
(target 0xde1)  level 0, d3d format WINED3DFMT_DXT5, internal format 0, width
1024, height 1024, gl format 0, gl type=0
Mesa: User error: GL_INVALID_VALUE in glTexImage2D(internalFormat=GL_FALSE)
err:d3d_surface:surface_allocate_surface >>>>>>>>>>>>>>>>> GL_INVALID_VALUE
(0x501) from glTexImage2D @ surface.c / 2338
fglrx:
trace:d3d_surface:surface_allocate_surface (0x20490550) : Creating surface
(target 0xde1)  level 0, d3d format WINED3DFMT_DXT5, internal format 0x83f3,
width 1024, height 1024, gl format 0x1908, gl type=0x1401
trace:d3d_surface:surface_allocate_surface glTexImage2D call ok surface.c /
2311

I guess, the mesa-gallium detection does not cover the DXT5-Textures, as the
fglrx detection of wine initialization does.

I'll try to do some debugging myself, but if there are hints or solution ideas
of experienced wine-devs, that would be great.

You need (32-bit) libtxc_dxtn for s3tc support with r600g.

Thanks a lot for the hint, but I have it installed for sure. 
Otherwise I'd get the "Mesa warning: couldn't open libtxc_dxtn.so, software
DXTn compression/decompression unavailable" as I'm running with MESA_DEBUG=1

Any further ideas ? You know where the internal- and gl-format are associated
for the surface ? Or is it the result of some conversion function ?

The other part that's important for s3tc with r600g is the kernel. You need a
fairly recent version, IIRC at least 2.6.39 (but you might as well go straight
for 3.0). The GL format setup is done based on the table at
http://source.winehq.org/git/wine.git/blob/04d541c26d4f50af2bf306dc11943bd12...
Getting 0 for internal format pretty much means the required extension wasn't
found, in this case that would be GL_EXT_texture_compression_s3tc. If you run
with WINEDEBUG=+d3d_caps you'll probably see that it's not in the list of
detected extensions in wined3d_adapter_init_gl_caps(). If this is due to the
kernel being too old, it's probably not in your glxinfo output either.

Thanks a lot for the help...
It actually was the case that s3tc was not shown in glxinfo, which took me to
this article http://www.phoronix.com/scan.php?page=news_item&px=OTEwNg ...

Adding a
export R600_ENABLE_S3TC=1
made it work... :-)

Running SC2 on Gallium now... :-)

Performance is still low and it crashed after first game, but it's somewhat
running... :-)

Thanks Henri...

FIXED is only for bug that were actually fixed in Wine. And yeah,
R600_ENABLE_S3TC=1 can work in some cases. IIRC there went some related fixes
into .39 as well though, so getting the newer kernel is still the preferred way
to make it work.
