It looks ready to go (as in I couldn't see any problems in this series). Since we are making changes a bit wider than rc6/rps internals (touching pcode and runtime_pm), we could do with an ack or two from other interested parties to make sure we are not digging ourselves into a hole. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
