Comment 2 Chris Wilson 2019-01-18 20:34:48 UTC 
This is close to being a WONTFIX as for us it is nigh on impossible to fix. perf allocates from inside per-cpu smpboot callback, tainting the cpuhp mutex used for stop-machine. We need to use stop-machine from any context to prevent the HW issue... Or we need to do something like revoke all mmaps before any GGTT update (which sounds even worse than stop-machine). Even breaking away from struct_mutex won't help here as the same chain will be created for ggtt->vm.mutex (both required from inside i915_gem_fault and then taking stop-machine for the ggtt insertion).

So the most realistic coarse of action would be to avoid the same perf lock being required inside cpuhp and around the perf_event.
Comment 3 Chris Wilson 2019-01-18 20:36:40 UTC 
Fwiw, the same perf <-> cpuhp chain prevent us from using stop-machine inside reset to serialise memory traffic against fence register reinitialisation.
