From 833ee5c4ab36937a99e63935d7f06bc2c1f9343b Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 16 Jul 2010 10:39:16 -0400 Subject: [PATCH] drm/radeon/kms: remove rs4xx gart limit We used to limit the rs4xx gart aperture to 32 MB, but I suspect that was due to not meeting the alignment requirements of the aperture. This patch should only be applied after: "drm/radeon/kms: fix gtt MC base alignment on rs4xx/rs690/rs740 asics" has been applied. This patch should probably soak for a bit in d-r-t.
