From 9a99e904cc5b08f8eda2366135404fe72dae16af Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Tue, 11 Jun 2019 16:46:13 +1000 Subject: [PATCH] drm/nouveau/kms/gv100-: add support for plane zpos property Has a nice side-effect that we only update HW for this when it changes now, rather than every time we do a page flip.
