           Summary: r200 falls back to software when clearing FBOs
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r200
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: stefandoesinger at gmx.at


Created an attachment (id=50814)
 --> (https://bugs.freedesktop.org/attachment.cgi?id=50814)
Sample application

glClear(GL_COLOR_BUFFER_BIT) causes a software fallback when a FBO is bound.
The line in the debug output that signals this fallback is

r200Clear: swrast clear, mask: 100

0x100 is BUFFER_BIT_COLOR0 as far as I can see, which is indeed not handled in
that function. I have attached a sample application that is a side product of
attempting to reproduce bug 40552. The sample doesn't crash(yet), but it
reproduces the software fallback.
