radeon - ring 0 stalled - GPU lockup - SI

Submitted by Julien Isorce @cap

Assigned to Default DRI bug account

Link to original bug (#107545)

Description

  • 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.
