Jetson TK1 Pro graphics stack without X11 dependency

I just heard that nVIDIA has a graphics stack on which you can run things directly on top of the hardware, basically without the need to have an intervening windowing system, such as X11. This presumably is delivered along with Jetson TK1 Pro. Is this stack available somewhere as a download and is it possible to make it run also in Jetson TK1? In the end, we will have a custom TK1 32-bit board and we want to avoid using X11 and we want to use a Wayland based library instead.
