We need to bump the karma of the drm_sched job in order for the context that we just recovered to get correct feedback that it is guilty of hanging.
Without this feedback, the application may keep pushing through the soft recoveries, continually hanging the system with jobs that timeout.
There is an accompanying Mesa/RADV patch here https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/27050 to properly handle device loss state when VRAM is not lost.
With these, I was able to run Counter-Strike 2 and launch an application which can fault the GPU in a variety of ways, and still have Steam + Counter-Strike 2 + Gamescope (compositor) stay up and continue functioning on Steam Deck.
