From cb9e59d7e999c68b79f23d6016b08fc5d0bb8a8d Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 5 May 2016 16:03:57 -0400 Subject: drm/amdgpu: Support DRM_MODE_PAGE_FLIP_ASYNC (v2) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When this flag is set, we program the hardware to execute the flip during horizontal blank (i.e. for the next scanline) instead of during vertical blank (i.e. for the next frame).
