To begin with, define the compute class/engine common functions, based on the existing render ones. v2: - Add kerneldoc for drm_i915_gem_engine_class since we're adding a new element to it. (Daniel) - Make engine class <-> guc class converters use lookup tables to make it more clear/explicit how the IDs map. (Tvrtko) v3: - Don't update uapi for now; we'll just include the driver-internal changes for the time being.
