From d8852c3446ddeab300c4ae397d658b8715535102 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 19 Dec 2013 14:03:36 -0500 Subject: [PATCH] drm/radeon/dpm: add late_enable for KB/KV Make sure interrupts are enabled before we enable thermal interrupts. Also, don't powergate uvd, etc. until after the ring tests.
