Looks like you are still running this without the latest hang fix since i see the deadlock again, but actually what i forgot to ask you is to load amdgpu with vm_fault_stop=2 to freeze the ASIC once VM_FAULT is encountered - sorry about that. So please retest with amdgpu.vm_fault_stop=2 paramete

OK, just apply the following to your amdgpu_dm_do_flip function and see if GPU reset does proceed after you experience the hang. diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c index d59bafc..586301f 100644 --- a/drivers/gpu/drm/

Re: "ring gfx timeout" with Vega 64 on mesa 19.0.0-rc2 and kernel 5.0.0-rc6 (GPU reset still not works)

Sure, that probably would be the solution, one missing detail here (besides confirming with the debug prints that this is the scenario we are hitting) is WHY we even stuck in reservation_object_wait_timeout_rcu, in amdgpu_device_pre_asic_reset (during GPU reset) we are first forcing all outstan

Re: "ring gfx timeout" with Vega 64 on mesa 19.0.0-rc2 and kernel 5.0.0-rc6 (GPU reset still not works)

The MAX_SCHEDULE_TIMEOUT is probably not a good idea on the wait in DM. I wonder if we could just do shorter wait and skip the FB update/programming if it fails after some reasonable amount of time. This would still allow recovery to happen at least even if the display isn't showing the right b

Re: "ring gfx timeout" with Vega 64 on mesa 19.0.0-rc2 and kernel 5.0.0-rc6 (GPU reset still not works)

I suspect the issue is that amdgpu_dm_do_flip is holding the BO reserved and then stack waiting for fences to signal in reservation_object_wait_timeout_rcu (which won't signal because there was a VM_FAULT). Then when we try to shutdown display block during reset recovery from drm_atomic_helper_
