Comment # 3
on bug 99219
from Samuel Pitoiset
It's actually a regression in mesa, works fine with 13.0.2. After bisecting, the first bad commit is: commit ed3190b3f3a776fc8c75b1e6130a88079166d115 Author: Marek Olšák <marek.olsak@amd.com> Date: Sun Nov 13 18:41:43 2016 +0100 radeonsi: don't export ClipVertex and ClipDistance[] if clipping is disabled This is the first user of optimized monolithic shader variants. Cull distances can't be disabled by states. Tested-by: Edmondo Tommasina <edmondo.tommasina@gmail.com> Reviewed-by: Nicolai Hähnle <nicolai.haehnle@amd.com> But this doesn't seem to be actually related to the clip planes optimization because if you replay the trace with R600_DUMP_SHADERS=y, it no longer crashes. If my understanding is correct, it won't compile shaders asynchronously. Forcing num_compiler_threads = 1 in si_pipe.c also "fixes" the hang.
