From 7082e7a438db2abf13e4e1fa904875034de88b6b Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Thu, 12 Dec 2019 13:53:45 +0100 Subject: drm/virtio: batch display update commands. When the driver submits multiple commands in a row it makes sense to notify the host only after submitting the last one, so the host can process them all at once, with a single vmexit. Add functions to enable/disable notifications to allow that. Use the new functions for primary plane updates.
