Bug ID: 89944 Summary: GPU crash in Civilization 5 Product: Mesa Version: git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: sami.liedes@iki.fi QA Contact: dri-devel@lists.freedesktop.org

Created attachment 114935 --> https://bugs.freedesktop.org/attachment.cgi?id=114935&action=edit dmesg

Civilization 5, with all DLC, causes a GPU crash on recent git (490621f) on Radeon R9 270. The game works perfectly on mesa 10.4.2 from Debian unstable, though. Hardware and kernel are x86-64, but the game (and obviously mesa) is 32-bit.

The crash happens when the game is loaded, probably where the map would first get drawn.

Mesa was built in a 32-bit chroot and configured with

./configure --prefix=/home/sliedes/local/mesa32 --build=i686-pc-linux-gnu --host=i686-pc-linux-gnu --with-gallium-drivers=radeonsi --with-egl-platforms=drm,x11 --enable-driglx-direct --enable-gles1 --enable-gles2 --enable-glx-tls --enable-texture-float

LLVM version is 3.6.0, built in release mode.

glsl: Optimize "if (cond) discard;" to a conditional discard.

st_glsl_to_tgsi and ir_to_mesa have handled conditional discards for a long time; the previous patch added that capability to i965.

I can also confirm that reverting that commit on top of recent HEAD (4deca127) fixes the issue.

I can attach R600_DEBUG=ps,gs,vs output from the offending commit and its parent if you think comparing them is of any use.

--- Comment #4 from qaridarium thomas.frech.qaridarium@gmail.com --- I think I do have the same problem.

I do have a hd7850 and I use the oibaf PPA to run the GIT code

That would be useful.
