I did some quick and dirty plot this morning. What I did are replacing the
kernel gpu driver source code, writing recipes for gpu-viv-bin-mx6q,
xf86-dri-vivante and xf86-video-imxfb-vivante. It compiles fine and I test
the simple triangle sample from the sdk. The result is...it only works in
fullscreen. If I create a smaller window in XCreateSimpleWindow other than
full screen size, it gives me a blank window.
