Bug ID: 86864
Summary: [rv6xx] RADEON_FLAG_GTT_WC causes GPU to reset when
playing Second Life / other games
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/r600
Assignee: dri-devel at lists.freedesktop.org
Reporter: shawn.starr at rogers.com
I've git bisected from git master and came up with this commit that causes GPU
to lock up (DRI driver locks up, I can ssh an reboot the laptop cleanly
however).
Kernel: 3.17.2-300.fc21.x86_64
[root at devbox mesa-20141127]# git bisect good
7b4276d7acf2e0f77044cb50caa6ad936fa78786 is the first bad commit

r600g,radeonsi: Always use GTT again for PIPE_USAGE_STREAM buffers
Putting those in VRAM can cause long pauses due to buffers being moved
into / out of VRAM.

With this reverted from this point back to Sept 7th, I have stability with the
r600g DRI driver.
