From 5a5a0c64a99d7542c48c99d1a8bbb49e665842be Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 15 Sep 2009 22:57:36 +0200 Subject: drm/i915: implement fastpath for overlay flip waiting As long as the gpu can keep up, neither the cpu (waiting for gpu) nore the gpu (waiting for vblank to do an overlay flip) stalls.
