GPU Hang/reset/forced reboot - latest mesa - mesa-demos/gloss
Hi,
tl;dr;: there I am, typing gl<tab>
expecting glinfo
when gloss
comes up, [enter]
aaaand the GPU hangs.
What is gloss ? well it's a "Specular reflection demo". I have it because I have mesa-demos installed.
Anyway:
LIBGL_DEBUG=1 MESA_DEBUG=1 LIBGL_ALWAYS_SOFTWARE=1 gloss
# produces a nice revolving cylinder - in software
LIBGL_DEBUG=1 MESA_DEBUG=1 gloss
# produces a black screen / purple dots freeze hang / forced reboot
I would do RADV_DEBUG=hang - but as it's not vulkan, what can I do to get more info?
tiny bit of journalclt -k:

PS: mesa demos should work or are they deprecated/not supported ?
SETUP: AMD 5700 XT - on Mesa 21.3.0-devel (git-591afd1d) - which is the latest main as of time of writing
