From 0f768cac548531423d88866125d5d28068a65a8f Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Tue, 26 Oct 2010 17:17:15 -0400 Subject: [PATCH] drm/radeon/kms: fix handling of tex lookup disable in cs checker on r2xx There are cases when multiple texture units have to be enabled, but not actually used to sample. This patch checks to see if the lookup_disable bit is set and if so, skips the texture check.
