From 0690a229c69f40a6c9c459ab455c85df49822525 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Sat, 7 Jun 2014 11:31:25 -0400 Subject: [PATCH] Revert "drm/radeon: use variable UVD clocks" This caused reduced performance for some users with advanced post processing enabled. We need a better method to pick the UVD state based on the amount of post processing required or tune the advanced post processing to fit within the lower power state envelope. This reverts commit 14a9579ddbf15dd1992a9481a4ec80b0b91656d5.
