Priority: medium Bug ID: 73785 Assignee: dri-devel@lists.freedesktop.org Summary: Team Fortress 2 causes random GPU stalls on radeonsi Severity: normal Classification: Unclassified OS: Linux (All) Reporter: xamaniqinqu@gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/radeonsi Product: Mesa
Created attachment 92376 --> https://bugs.freedesktop.org/attachment.cgi?id=92376&action=edit dmesg output related to the GPU stall.
Overview: The game "Team Fortress 2" causes the GPU to stall randomly. The stalls sometimes resolve by themselves after ~1 min, but will occur again rapidly.
Steps to reproduce: 1) Install "Team Fortress 2" through Steam ( http://store.steampowered.com/app/440/ ). 2) Start the game, join a map. 3) Play until the GPU hangs. 4) Optionally: wait until GPU recovers.
Actual results: Frequent GPU stalls while playing Team Fortress 2. Sometimes video output is restored after ~1 min.
Expected results: No stalls.
Build date and platform: Build date of all components: 01/18/2014 Linux kernel version: 3.13-rc8 x86_64 Mesa: git (566e0ddfd01dbadd75462fed5a3f141b9f494028) LLVM: 3.5-svn (commit 199570)
Additional information: I am running on a Radeon HD 7970 with DVI output at 2560x1440. Dynamic power management is enabled. Disabling Hi-Z does not alleviate the problem. The output of "dmesg 'drm|radeon'" has been added as an attachment. I could not reproduce the issue (yet) in another Source engine title, "Left 4 Dead 2".
