Thanks for the quick answer.

1) GPU is Mali T628, on Exynos5422 ARM platform (Odroid XU4)

2) OpenGL-ES 3.1

3)Yes, EGL is working, apps like wayland-simple-egl, glmark2-es2-wayland work, and heavier apps like gnome-maps, kodi work too. gnome-shell and weston are also EGL-accelerated via GBM(KMS).

4) here's the output from waylandes2info:

Here's an older grab that shows weston-simple-egl, webkit-gtk 2.12 (epiphany) and glmark2-es2-wayland working: https://www.youtube.com/watch?v=AkSgm4JF81U. I hope to get to use USE_GSTREAMER_GL on 2.14, since in 2.12 it was not ready.
