While you can run piglit on released mesa versions, it's much more useful to see results on the latest and greatest. You can get instructions on building a git mesa from InstallNouveau. The recommended parameters that avoid most of the hangs/crashes that we've seen and aren't a direct result of mesa issues:
piglit $ ./piglit-run.py -x glx -x streaming-texture-leak -1 --dmesg tests/gpu.py \ ~/piglit-results/nvXX-`date +%Y-%m-%d`-$USERThis should generate a file
~/piglit-results/.../main. You can then run piglit-summary(-html) on it, and/or send it to me. Find me on IRC in #nouveau on irc.freenode.net.
