@alzer89 that sounds neat, good catch!
I’ve not been back to the passthrough front yet (spent so much those last months that I thought the software side of things was needing some love) so incidently I have not yet run into the GPU reset problems yet.
From the little I’ve been following in the meantime, I have great hopes that some work amgpu/dc has had recently will finally unlock us. “Just” need to take the time to dig into this anew.
