From e8942889cbc0289d287842f8aa23612ec3ed2ff5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Christian=20K=C3=B6nig?= Date: Sun, 7 Jan 2018 10:18:57 +0100 Subject: [PATCH 3133/4131] drm/amdgpu: fix 64bit BAR detection MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Windows added by the BIOS are not marked as 64bit because they are usually not changeable anyway. This fixes large BAR support on my new Ryzen build system.
