From d904ef9b00a4473af16766e99f17bdbb5f0fde65 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Tue, 17 Nov 2009 06:29:46 +1000 Subject: drm/radeon/kms: add support to atom parser for FB read/write FB read/write really doesn't need to access the actual VRAM, we can just use a scratch area. This is required for using atom displayport calls later.
