From dca5086a90c9ec64f4e0de801a659508202b0640 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Mon, 30 Sep 2013 19:11:24 -0400 Subject: [PATCH] drm/radeon/dpm: disable multiple UVD states Always use the regular UVD state for now. This fixes a performance regression with UVD playback on certain APUs.
