We now have working reverse-engineered 2D and 3D/OpenGL acceleration in i.mx6 parts thanks to the Etnaviv project.
For either the WandBoard or UDOO follow our instructions building either the v4.9.x (lts), v4.10.x or later kernel’s, then install the xserver-xorg-video-armada-etnaviv package, along with the xorg.conf changes needed.
