From dd017d01c3d96e48abd6fe6ccce4ef977fb5e10b Mon Sep 17 00:00:00 2001 From: Christian König Date: Wed, 27 Jan 2021 13:20:40 +0100 Subject: drm/amdgpu: enable freesync for A+A configs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some newer APUs can scanout directly from GTT, that saves us from allocating another bounce buffer in VRAM and enables freesync in such configurations. Without this patch creating a framebuffer from the imported BO will fail and userspace will fall back to a copy.
