From b866d1334ba2d544bc575d75357dea6bdcdc7f46 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 14 Jun 2012 22:06:36 +0200 Subject: [PATCH] drm/radeon: add some additional 6xx/7xx/EG register init - SMX_SAR_CTL0 needs to be programmed correctly to prevent problems with memory exports in certain cases. - VC_ENHANCE needs to be initialized on 6xx/7xx.
