From c8b4f288f4276078f169a404e2d1ac1535f82b93 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Tue, 23 Aug 2016 09:12:21 -0400 Subject: [PATCH] drm/amdgpu: switch UVD code to use UVD_NO_OP for padding MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Replace packet2's with packet0 writes to UVD_NO_OP. The value written to UVD_NO_OP does not matter.
