From 151b5d7fd35876120dc744f93865e4c7dc2c1f36 Mon Sep 17 00:00:00 2001 From: Huang Rui Date: Tue, 27 Feb 2018 13:43:59 +0800 Subject: [PATCH] drm/amdgpu: fix to disable powergating in hw_fini MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We need enable CGPG and GFXOFF together. If only enable one of them, this system will get hang after startx (do draw command). So when gfxoff is disabled, it also need disable CGPG after that.
