[Mesa-dev] [PATCH 00/47] WIP: fp64 support for r600g

[Gert Wollny]

Hello Elie, 

thanks for you work on this. I'd thought I'd share my test results on
BARTS:

- your tree was build with debug enabled, so some of the crashes 
  relate to assertion failures (at least one in r600/sb which also 
  fails with R600_DEBUG=nosb).
  
- piglit results 
   * arb_gpu_shader_fp64 900/1311  passed
   * glsl-4.00 822/1225 passed
   * Crashes in total are 402 and 485 failures.   
   
  The complete summary is at
  https://www.dropbox.com/s/qn283a9s0cd2uru/shaders-fp64-only.tgz?dl=0


In  kern.log I got 

- lots of traps: 
  shader_runner[..] trap int3 ip:.. sp:.. error:0 in r600_dri.so ..

- many segfaults in r600_dri.so

- and some GPU lockups+reset, but no system crashes:
