From 700a0cc088a42a2ed92c6f961534fdb38588af87 Mon Sep 17 00:00:00 2001 From: Jerome Glisse Date: Wed, 13 Jan 2010 15:16:38 +0100 Subject: [PATCH] drm/radeon/kms: Use radeon_agp_disable when disabling AGP Use same common function to disable agp so we replace the GART callback by the proper one when we do so. This fix oops if radeon_agp_init report failure. This patch also move radeon_agp_init out of *_mc_init for r600 & rv770 so that we can have a similar behavior than for previous hw, ie if agp_init fails it will fallback to GPU GART and disable AGP.
