From de31fe81a869c80b3cc08cb648640cf617e0d09c Mon Sep 17 00:00:00 2001

Subject: [PATCH] vc4: Switch back to using a local copy of vc4_drm.h.
Needing to get our uapi header from libdrm has only complicated things.
Follow intel's lead and drop our requirement for it.
Generated from 056f4f02abb7e9e4a0cf0cda0211586df5e43842 of drm-misc-next
(cherry picked from commit 1facea3486e3dd4e4a6cf561a725b9c4312ca58a)

From 0670340bc6730e3de453e064b8a883a829900945 Mon Sep 17 00:00:00 2001
From: Eric Anholt <eric@anholt.net>
Date: Mon, 8 May 2017 16:43:06 -0700
Subject: [PATCH] vc4: Drop the u_resource_vtbl no-op layer.
We only ever attached one vtbl, so it was a waste of space and
indirections.
(cherry picked from commit 76e4ab57158de8a568572f1acb1d679ce8abb288)

Subject: [PATCH] vc4: Drop pointless indirections around BO import/export.
I've since found them to be more confusing by adding indirections than
clarifying by screening off resources from the handle/fd import/export
process.

Subject: [PATCH] vc4: Set shareable BOs as T tiled if possible.
X11 and GL compositor performance on VC4 has been terrible because of our
SHARED-usage buffers all being forced to linear. This swaps SHARED &&
!LINEAR buffers over to being tiled.
This is an expected win for all GL compositors during rendering (a full
copy of each shared texture per draw call), allows X11 to be used with
decent performance without a GL compositor, and improves X11 windowed
swapbuffers performance as well. It also halves the memory usage of
shared buffers that get textured from. The only cost should be idle
systems with a scanout-only buffer that isn't flagged as LINEAR, in which
case the memory bandwidth cost of scanout goes up ~25%.
