[Intel-gfx] [PATCH 05/22] drm/i915/selftests: Take GEM runtime wakeref

Chris Wilson chris at chris-wilson.co.uk
Mon Mar 25 09:03:56 UTC 2019


Transition from calling the lower level intel_runtime_pm functions to
using the GEM runtime_pm functions (i915_gem_unpark, i915_gem_park) now
that they are decoupled from struct_mutex. This has the small advantage
of reducing our overhead for request emission and ensuring that GEM
state is locked awake during the tests (to reduce interference).
