--- Comment #11 from Dave Witbrodt dawitbro@sbcglobal.net --- (In reply to comment #10)
I have the gpu lockups too on an 7750 in different apps, for instance xonotic. I did a bisect and it led to this commit:
e8f9195e5fb34a45783d6491d2e0305a0b137439 is the first bad commit commit e8f9195e5fb34a45783d6491d2e0305a0b137439 Author: Axel Davy axel.davy@ens.fr Date: Thu Aug 15 12:47:58 2013 +0200
gallium, intel: Implements new __DRI_IMAGE_USE_LINEAR andPIPE_BIND_LINEAR flags to enforce no tiling.
Signed-off-by: Axel Davy <axel.davy@ens.fr>And indeed reverting it seems to fix the lockups.
I can confirm that this commit was the problem in my case. That commit introduced a boolean error in src/gallium/drivers/radeonsi/r600_texture.c which was later fixed in 49f2ba2c.
My Mesa build on Sep. 2 was before e8f9195e, and on Sep. 6 was after. The new Mesa I built today was only failing because my LLVM 3.4 did not include the necessary patch for Marek's transform feedback work. Once I update LLVM, no GPU failures were observed and all was well again.
Hopefully José will have no more problems if he gets a new version of Mesa at or after commit 49f2ba2c. If he uses a version after 2b71b3d4, he will need LLVM 3.4 at svn190575 or later.
