From: Alex Deucher Date: Fri, 25 Sep 2009 22:33:08 +0000 (-0400) Subject: drm/radeon/r600: fix offset handling in CS parser X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=210bed8f827471e271f894fb99ee879a5d27cf30;p=openwrt%2Fstaging%2Fblogic.git drm/radeon/r600: fix offset handling in CS parser Need add reloc offset to the offset in the actual packet. Fixes use of the DRAW_INDEX packet by the 3D driver.
