Priority: medium Bug ID: 74679 Assignee: dri-devel@lists.freedesktop.org Summary: Pyrit crashes with segmentation fault Severity: normal Classification: Unclassified OS: Linux (All) Reporter: Nzatkovich@gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa
Created attachment 93617 --> https://bugs.freedesktop.org/attachment.cgi?id=93617&action=edit This is the output of "R600_DEBUG=cs pyrit selftest", and the piglt all_cl test results of both GPUs
OS: Ubuntu 13.10 with Linux kernel 3.13.1 LLVM/Clang: latest git from apt repos, 200925 libclc: git, 20140205 Mesa: git, 201402061930
Graphics card: Radeon R9 270X, aka AMD PITCAIRN
Every time I run a Pyrit selftest, it crashes with a segmentation fault. I have tried this on my laptop with the same setup as above, except this had a Radeon HD 6750M (aka AMD TURKS), and it ran fine.
I have attached the output of "R600_DEBUG=cs pyrit selftest".
I have also attached the output of the piglit all_cl tests for both the 6750M and the R9 270X.

--- Comment #1 from Nick Zatkovich Nzatkovich@gmail.com --- Also, I forgot to mention, I was recompiling pyrit every time I updated any of those repos, and it was from the pyrit svn on google code.

--- Comment #2 from Tom Stellard tstellar@gmail.com --- It works for me with these two patches: http://people.freedesktop.org/~tstellar/0001-SelectionDAG-Factor-ISD-MUL-low... http://people.freedesktop.org/~tstellar/0002-SelectionDAG-Use-helper-functio...
Can you test these? I have some other uncommitted patches in my tree, so if it still doesn't work for you with these patches, I will push the branch I'm using somewhere so you can test it.

--- Comment #3 from Nick Zatkovich Nzatkovich@gmail.com --- Created attachment 93640 --> https://bugs.freedesktop.org/attachment.cgi?id=93640&action=edit Piglit tests on the R9 270x before and after the patch

--- Comment #4 from Nick Zatkovich Nzatkovich@gmail.com --- Yes, it works! Thank you. Lets hope these patches land in upstream soon.
for posterity's sake, I've uploaded the piglit tests before and after the patch.
