From 46fcd2b3dbf58a448b621d3d2f492a0e90223a3a Mon Sep 17 00:00:00 2001 From: Jerome Glisse Date: Thu, 3 Jun 2010 19:34:48 +0200 Subject: [PATCH] drm/radeon/kms: Force HDP_NONSURF to maximum size HDP non surface should cover the whole VRAM but we were misscomputing the size and we endup in some case not covering the VRAM at all (if VRAM size were > 1G). Covering more than the VRAM size shouldn't be an issue.
