From afa83e4942997a92e5c763754bf6dde907bf20cc Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christian=20K=C3=B6nig?= Date: Thu, 10 Apr 2014 16:11:36 +0200 Subject: [PATCH] drm/radeon/uvd: use lower clocks on old UVD to boot v2 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit commit e45187620f9fc103edf68fa5ea78e73033e1668c upstream. Some RV7xx generation hardware crashes after you raise the UVD clocks for the first time. Try to avoid this by using the lower clocks to boot these.
