From 7fc86860cf73e060ab8ed9763010dfe5b5389b1c Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Mon, 5 Nov 2007 10:45:27 +1000 Subject: radeon: set the address to access the GART table on the CPU side correctly This code relied on the CPU and GPU address for the aperture being the same, On some r5xx hardware I was playing with I noticed that this isn't always true. This fixes issues seen on some r400 cards.
