Summary: GPU lockup in Team Fortress 2 Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: Enrico_m@gmx.de
After updating mesa to current git I always get a GPU lockup when the game is about to start. After git bisect I got the following commit:
commit 18dcbd358f1d4fd5e4a40fa26c6d3bf99485884e Author: Tom Stellard tstellar@gmail.com Date: Sun Mar 27 01:17:43 2011 -0700
prog_optimize: Fix reallocating registers for shaders with loops
Registers that are used inside of loops need to be considered live starting with the first instruction of the outermost loop.
