Tested with: MESA_EXTENSION_OVERRIDE=GL_ARB_gpu_shader5 ./shader_runner ../tests/spec/arb_gpu_shader5/execution/built-in-functions/fs-bitfieldReverse.shader_test -> green output, so this should be ok the test was not change though...

...his is output in response to a interrupt and MP trap generated by the hardware, read out with nv_rd32(priv, TPC_UNIT(gpc, tpc, 0x648)); (see gf100_gr_trap_mp). I assume some of the tessellation evaluation invocations get killed, but I have no proof of this. I also see this: TRAP ch 5 [0x003facf000 shader_runner[19044]] I would imagine that's some floating point number ending up in the register instead of an address, but the fp32 value of it (1.35107421875) does not seem familiar. Even when all the triangles show up, I still see the error on the GK208, so I'm not sure if they're the same issu...

...shaders (well, related to textures), and there are plenty of other texture2D-using tests. I looked at the mmt traces, and they seem pretty reasonable. What's unique about this test is that it uses a 0.01 value in the texture rather than the more common 1/-1. FWIW the failure looks like: $ bin/shader_runner tests/shaders/glsl-fs-lots-of-tex.shader_test -auto Probe color at (187,187) Expected: 0.400000 0.000000 0.000000 Observed: 0.266667 0.000000 0.000000 PIGLIT: {'result': 'fail' } So it's getting a value... just not the right one. The blit is being done from RGBA32_FLOAT to...
