From 965ebe3d5d641925e0014a5a8c967fe579929b1d Mon Sep 17 00:00:00 2001 From: Michel Dänzer Date: Wed, 24 Jul 2019 17:56:28 +0200 Subject: drm/amdgpu: Update pitch on page flips without DC as well MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit DC already handles this correctly since amdgpu minor version 31. Bump the minor version again so that xf86-video-amdgpu can take advantage of this working without DC as well now.
