From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx> Current processing landscape seems to be more and more composed of pipelines where computations are done on multiple hardware devices. Furthermore some of the non-CPU devices, like in this case many GPUs supported by the i915 driver, actually support priority based scheduling which is currently rather inaccessible to the user (in terms of being able to control it from the outside).
