           Summary: Mesa 7.8.1 for the RV250 or Radeon 9000 is broke
           Product: Mesa
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r200
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: brian@rapsure.net


I've tested with two different computers in regards to the RV250 Mesa code.
This code has been broke since at least Mesa 7.5. The two computers have
different hardware with the only common piece of hardware being the video card.
So I believe that the other pieces of hardware have very little to do with this
bug. One computer is an Intel Pentium III, and the other is an AMD Athlon (Slot
A version). Both computers are running Gentoo. The Pentium III is running
xorg-server-1.8.1, and the AMD Athlon is running xorg-server-1.7.6. Both
computers exhibit the exact same behavior in regards to the running of OpenGL
programs. 

The test:
Run glxgears

The results:
A blank window with no gears. 

Expected results:
A window that has spinning gears.

Other programs known to not display correctly too:
googleearth, trigger.


Due to the wide differences in hardware and a similar discrepancy in the
software the recreation of this bug should be quite simple as just upgrading to
Mesa 7.8. I don't experience this behavior on the ATI Radeon 9250 with the
RV280 core.

If you are using kms, this was fixed in:
http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=cf22f20ade30f8c03955324aaf27b1049e182600

The computers are using UMS and so that wouldn't be the case. I could try KMS
to see if the bug is exhibited there, but I wanted the kernels be the same. Do
you want me to try KMS?

AFAICT the fix applies to UMS, not KMS.

Sorry; yes, it is UMS.  Brian, that patch should fix your issue.

I tested the patch and it fixes the issue. Now if this small patch could make
it into the next point release that would be really nice.
