From: Daniele Ceraolo Spurio <daniele.ceraolospurio@xxxxxxxxx> A few advantages: - Prepares us for the planned split of display uncore from GT uncore - Improves our engine-centric view of the world in the engine code and allows us to avoid jumping back to dev_priv. - Allows us to wrap accesses to engine register in nice macros that automatically pick the right mmio base.
