you might want to check out this branch that is actively working on
integrating the linux-4.6 DRM code in 11 and CURRENT:

https://github.com/FreeBSDDesktop/freebsd-base-graphics

There is a wiki that offers some pointers on getting started.  I am
personally running this code on skylake and haswell intel GPU's.  There
has also been a bit of work on AMD GPU's but I am unsure of the current
state of that work.


Hope this helps!
