From 9ecc6eabd8fee0972de3f23bd66d1a54b1781fa6 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Fri, 13 Dec 2019 15:34:50 +0200 Subject: [PATCH] drm/i915/fbc: Move the plane state check into the fbc functions MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Instead of dealing with the presence/absence of the primary plane in the higher level pre/post plane update code let's move all that into the fbc code itself. Now the higher level code doesn't have to think about FBC details anymore.
