From 02c9f7fa4e7230fc4ae8bf26f64e45aa76011f9c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christian=20K=C3=B6nig?= Date: Tue, 13 Aug 2013 11:56:51 +0200 Subject: [PATCH] drm/radeon: rework UVD writeback & [rw]ptr handling MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The hardware just doesn't support this correctly. Disable it before we accidentally write anywhere we shouldn't.
