From aef060e1147e33fc6d886f8376f1c6c6aa991073 Mon Sep 17 00:00:00 2001 From: Leo Liu Date: Thu, 27 Jul 2017 11:50:31 -0400 Subject: [PATCH] drm/amdgpu: disable vcn power control for now MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The dpm control for vcn has been moved to firmware, kernel always spins "amdgpu: [powerplay] pp_dpm_powergate_uvd was not implemented", each time when application runs, disable it for now till pg/cg. Also remove clock manual setting when dpm disabled, which was inherited from uvd.
