From 1d3fac0c2ae3bb1b054df2f203fdaf08a1d42370 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Mon, 7 Feb 2011 14:18:37 +1000 Subject: [PATCH] drm/nv50-nvc0: activate/update ds channel's framebuffer on modesets The hw doesn't really appear to be designed to be used the way we have to use it due to DRI2's design. This leads us to having to keep the flipped fb support active at all times.
