From c7853c6de126f6794946c592deed205c0ddad2d9 Mon Sep 17 00:00:00 2001
From: Olivier Fourdan <ofourdan@redhat.com>
Date: Wed, 3 Mar 2021 09:55:12 +0100
Subject: [PATCH xserver 01/27] xwayland: Move dmabuf interface to common
glamor code
This is preliminary work for hardware accelerated rendering with the
NVIDIA driver.
The EGLStream backend can possibly also use the dmabuf interface, so
move the relevant code from the GBM specific source to the common bits.
Signed-off-by: Olivier Fourdan <ofourdan@redhat.com>
(cherry picked from commit ae225417c0a0828ffb24e11eb4b968c34692e25a)
