commit 2e0986a58cc4f2e7f9e7ede19ec32b9c116d0068 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Oct 23 14:31:07 2019 +0100 drm/i915/gem: Cancel contexts when hangchecking is disabled Normally, we rely on our hangcheck to prevent persistent batches from hogging the GPU. However, if the user disables hangcheck, this mechanism breaks down. Despite our insistence that this is unsafe, the users are equally insistent that they want to use endless batches and will disable the hangcheck mechanism. We are looking at replacing hangcheck, in the next patch, with a softer mechanism, that sends a pulse down the engine to check if it is well. We can use the same preemptive pulse to flush an active context off the GPU upon context close, preventing resources being lost and unkillable requests remaining on the GPU after process termination.
