From ccaa2c12fba72f3e547d18e66820e2e6c5883113 Mon Sep 17 00:00:00 2001 From: =?utf8?q?J=C3=A9r=C3=B4me=20Glisse?= Date: Tue, 7 Jun 2016 17:43:04 -0400 Subject: [PATCH] drm/radeon: do not hard reset GPU while freezing on r600/r700 family MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Seems r600/r700 does not like hard reset while freezing for hibernation (regression due to 274ad65c9d02bdcbee9bae045517864c3521d530 which itself is a fix for hibernation on some GPU families). Until i can debug further issue with r600, let just disable this for r600/r700 as they are very similar family and bug affecting one likely affect the other.
