Nouveau - Feb 2018 - [PATCH 0/5] Fix deadlock on runtime suspend in DRM drivers

Hi

I've not been able to reproduce the original problem you're trying to
solve on amdgpu thats with or without your patch set and the above
"trigger" too

Is anything else required to trigger it, I started multiple DRI_PRIME
glxgears, in parallel, serial waiting the 12 seconds and serial within
the 12 seconds and I couldn't reproduce it

Regards

Mike

The discrete GPU needs to runtime suspend, that's the trigger,
so no DRI_PRIME executables should be running.  Just let it
autosuspend after boot.  Do you see "waiting 12 sec" messages
in dmesg?  If not it's not autosuspending.

Thanks,

Lukas

Hi

Yes I'm seeing those messages, I'm just not seeing the hangs

I've attached the dmesg in case you're interested
