Mesa3d: An implementation of the OpenGL API

[R300] Enabling S3TC texture support? (Ref: bug #8056)

Hi,

I have noticed that I am getting warnings like these in some OpenGL games:

*********************************WARN_ONCE*********************************
File r300_texstate.c function r300SetTexImages line 301
DXT 3/5 suffers from multitexturing problems!
***************************************************************************

When I asked about this on Phoronix, I was referred to bug #8056 where there is a Mesa patch which
would apparently fix this. Is there any chance that this patch could be applied to Mesa, please?

Thanks,
Chris

Re: [R300] Enabling S3TC texture support? (Ref: bug #8056)

If I remember correctly, the patches still had a couple of bugs that needed to
be worked out; they caused errors with the tiling when I tested them...

However, the AMD 3D documentation includes information on micro/macro tiling, so
it should be possible to fix those bugs...

I'll take a look at it as soon as I can. I currently can't get to bugs.fd.o.

Both the current stable branch and MESA git master have introduced rendering
errors into Half Life 2 running under Wine.

Doing a git bisect between the 7.0 release and the head of the current stable
branch blames deb5c56c77d385786d0b4fceed01cdee82f5355d:

[Bug 14798] New: glClear has no effect on a color buffer with an alpha channel in software mesa

http://bugs.freedesktop.org/show_bug.cgi?id=14798

           Summary: glClear has no effect on a color buffer with an alpha
                    channel in software mesa
           Product: Mesa
           Version: CVS
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
        AssignedTo: mesa3d-dev <at> lists.sourceforge.net
        ReportedBy: francois.bertel <at> kitware.com

OS: Linux gentoo, kernel 2.6.19-gentoo-r5

Using the software renderer of mesa, starting at id
ff73c783cc47361ff0dd819c82d067b4b85870dd , 

Take the source of mesa/progs/demos/renormal.c

1. Add glClearColor(0.0,0.5,0.0,0.0); at line 32:

   GLfloat scale = 0.6 + 0.5 * sin(Phi);
   glClearColor(0.0,0.5,0.0,0.0);
   glClear( GL_COLOR_BUFFER_BIT );

2. Run renormal, the background is green, so far so good.
