From: Aric Cyr Date: Thu, 16 May 2019 22:43:54 +0000 (-0400) Subject: drm/amd/display: program manual trigger only for bottom most pipe X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=4fd334122399a133ddaee8ef865eb10a1cf8000f;p=openwrt%2Fstaging%2Fblogic.git drm/amd/display: program manual trigger only for bottom most pipe [Why] We only want to manual trigger end-of-frame when the bottom-most pipe is flipped to prevent overlays from ending the frame too early. [How] Check that the manual trigger is only firing on bottom plane.
