What's most odd is that this is a one-off/sporadic! commit b37aef5f1b5a4788eca662de6cb33e1521a7e404 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Nov 30 09:42:31 2017 +0000 drm/i915/selftests: Wake the device before executing requests on the GPU To execute a requests requires us to have first woken the device, using the rpm wakeref (as the request needs to write to hardware to setup the context/ppGTT and execute on the GPU). So call intel_runtime_pm_get() around queuing the request; the request itself will then carry a wakeref until completion.
