From 22fd0fab3b512b5fcb4fd0b0668deeaa701511f9 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Wed, 2 Dec 2009 13:42:53 -0800 Subject: [PATCH] drm/i915: pageflip fixes This patch brings the tree up to date with some fixes that were in a more recent version of the page flipping patch you applied. It fixes pre-965 flip support, removes a leftover hack that forced alignment, and initializes the pipe & plane CRTC mappings.
