From: Sourab Gupta <sourab.gu...@intel.com> This patch series replaces Blitter ring based flips with MMIO based flips. This is useful for Media power well residency optimization. These may be enabled on architectures where Render and Blitter engines reside in different power wells. The blitter ring is currently being used just for command streamer based flip calls. For pure 3D workloads, with MMIO flips, there will be no use of blitter ring and this will ensure the 100% residency for Media well.
