From 32febd91951eb40d9e9437f10b967c87715d8ef5 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 21 Feb 2018 18:02:33 +0200 Subject: [PATCH] drm/i915: Require fence only for FBC capable planes MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit As only a subset of primary planes are FBC capable there's no need to waste fences on all of them. So let's skip the fence if the plane isn't even fbc capable. In the future we might extend this to skip the fence even for FBC capable planes if the crtc and/or plane state isn't suitable for FBC.
