Upstream glmark2 includes support for running glmark2 on a RaspberryPi via the
dispmanx interface, as is provided by "userland".
The build depends on x11, but this is a quirk of the upstream sources. One
can easily build a minimal image without any x11/wayland on which to run
dispmanx applications directly (including glmark2).
NOTE: unlike with other flavours, one can only build the dispmanx-eglv2
flavour on its own (this is a constraint of the glmark2 build)

+Subject: [PATCH] fix dispmanx build
+
+For when the user is building "--with-flavors dispmanx-glesv2", fixes a bunch
+of "redeclared as different kind of symbol" problems.
+
+This patch is almost entirely from:
+
https://github.com/glmark2/glmark2/commit/3b1a0f78d03ae126b78ee52a7c434809115e5993
+
+Which was created by: Alexandros Frantzis <alexandros.frant...@collabora.com>
+
+See:
+ https://github.com/glmark2/glmark2/issues/80
+
+My contribution is to tweak the wscript to link all the required libraries.

+The dispmanx flavour can only run fullscreen, therefore set the size to
+fullscreen when glmark2-es2-dispmanx is run.
