I > can't find source code to build it. you have an internal mesa problem up there. you will have to ask your maintainers/vendors who supplied it to you. :) (note that i do this with a lot of facetiousness in my tone here - because this is what the embedded world is. you get a supported driver from your soc vendor or - good luck. you're on your own). so why not ask olimex? > es2gears says - > > libEGL warning: DRI2: failed to open lima (search > paths /usr/lib/arm-linux-gnueabihf/dri:${ORIGIN}/dri:/usr/lib/dri) > EGL_VERSION = 1.4 (DRI2) > vertex shader info: > fragment shader info: > info: > > And generally says an FPS of about 15, which is woeful according to > reports from others. smells of a sw fallback. > I install from source code these things, in this order - > > https://github.com/robclark/libdri2 > https://github.com/linux-sunxi/libump > https://github.com/linux-sunxi/sunxi-mali > https://gitorious.org/lima/lima > https://github.com/ssvb/xf86-video-fbturbo > > Which according to a variety of build instructions, should be all I > need to get Mali 400 MP2 working on an A20. > > Then I build EFL, enlightenment, and other E stuff.
