Bug ID: 107545
Summary: radeon - ring 0 stalled - GPU lockup - SI
Product: DRI
Version: XOrg git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
Assignee: dri-devel@lists.freedesktop.org
Reporter: julien.iso...@gmail.com
* Steps to reproduce:
for i in {0..300}; do (glxgears &); done (note that 100 might be enough
instead of 300)
* Actual result:
ring 0 stalled, gpu locakup, reset and x11 stops and cannot restart. The only
way is to reboot.
* Expected result:
The fps goes very low the more there are glxgears instances and no gpu lockup,
like with intel gpu.
* Infos:
card W600
mesa 18.2,
kernel 4.15.0-15-generic,
LLVM 7.0.0
xorg 1.20.99.1
xf86-video-ati 18.0.1.
(same result with kernel 4.4.0-130, mesa 12.0.6, llvm 3.8.0, DRM 2.43.0)
I was playing with the apitrace here
https://bugs.freedesktop.org/show_bug.cgi?id=87278#c31 and decided to through
dozens of glxgears instances to see.
