From the cover letter:
With this patch series applied, it would become possible to display
(via Qemu GTK UI) Guest VM compositor's framebuffer (created in its
LMEM) on the Host without having to make any copies of it or a
costly roundtrip to System RAM. And, weston-simple-egl can now
achieve ~59 FPS while running with Gnome Wayland in the Guest VM.
