Thank you Robert! FBDEV is exactly what I need for this project so I'll start with option 1. I appreciate the work you have put into the beagleboard.org projects. I remember the beagleboard-xm had similar struggles. Why is SGX always so painful? I don't understand why TI's own instructions don't work (I couldn't make them work without manually editing parts of SGX, maybe I did something wrong).

We have two path's for users: Use the bone v4.4.x kernel, along with ti's 5.01.01.02's sdk, this will get you a "FBDEV" based acceleration (no x11/xorg/etc) This has the most beagleboard.org users.. https://github.com/RobertCNelson/bb-kernel/tree/am33x-v4.4 (or the rt varient) sgx build scripts are in the repo... Or you can use the newer ti sdk release, Start with our v4.4.x-ti based kernel: https://github.com/RobertCNelson/ti-linux-kernel-dev/tree/ti-linux-4.4.y Graphics Modules and user space is here: http://git.ti.com/cgit/cgit.cgi/graphics/omap5-sgx-ddk-linux.git/ http://git.ti.com/cgit/cgit.cgi/graphics/omap5-sgx-ddk- linux.git/log/?h=ti-img-sgx/1.14.3699939/k4.4 http://git.ti.com/cgit/cgit.cgi/graphics/omap5-sgx-ddk-um-linux.git/ http://git.ti.com/cgit/cgit.cgi/graphics/omap5-sgx-ddk-um- linux.git/log/?h=ti-img-sgx/1.14.3699939 They are "EGL" only... Wayland... Only TI has gotten these to work, we've been able to load the module... But nothing with the userspace lib's yet...
