           Summary: Incorrect rendering in SPECviewperf benchmark
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org

rendering comparison intel vs r600g

Using mesa from GIT + r600g, 7 first tests of SPECviewperf 11 show big
rendering errors (see attached image).
The same tests run well using an Intel based laptop (with Ubuntu 9.10).

Forgot to mention that tests 3/7 and 4/7 print some Mesa errors when running
with ST_DEUG=fallback,mesa :

test3 :
    Mesa: User error: GL_INVALID_OPERATION in glBegin(fragment program not
valid)
    Mesa: User error: GL_INVALID_OPERATION in glEnd
    Mesa: User error: GL_INVALID_OPERATION in glProgramStringARB(invalid ARB
fragment program option)

test4 :
    Mesa: User error: GL_INVALID_OPERATION in glProgramStringARB(invalid ARB
vertex program option)
    Mesa: User error: GL_INVALID_OPERATION in glProgramString(bad program)
    Mesa: User error: GL_INVALID_OPERATION in glProgramStringARB(invalid ARB
fragment program option)
    Mesa: User error: GL_INVALID_OPERATION in glDrawElements(vertex program not

This is a bug in SPECviewperf11, which relies on NV_fragment_program2
extension, even when it is not advertised.

Me and Brian have a patch that workarounds this by tolerating
NV_fragment_program2 's IF/ELSE/ENDIF opcodes.

This is exactly the same stratergy that AMD's fglrx drivers took: not advertise
NVIDIA's extension, but silently handle it.
