From 2ce529dac71ae7753981a587932d074fdb248608 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 28 Aug 2013 18:12:59 -0400 Subject: [PATCH] drm/radeon: split out radeon_uvd_resume from uvd_v4_2_resume MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit For powergating, we just need to re-init the registers, there is no need to restore the uvd BOs. This just adds needless work when powergating uvd for playback while the system is on. We only need to restore the uvd BOs on an actual resume from suspend or when the driver loads. This fixes multi-stream UVD playback on KB systems.
