Output Linux´s Video to VGA controller in FPGA Fabric through AXI on CV SoC

Hi,

I had a similar task but with creating a soundcard driver: http://stackoverflow.com/questions/34575899/creating-a-simple-audio-driver-for-a-cyclone-v-soc-linux

The dummy driver (snd-dummy) proved to be very useful for such a task, maybe you should have a look in the kernel sources for something similar on the video side.

Some links which I found in a quick search:

linux framebuffer documentation (somewhat dated) (https://www.kernel.org/doc/documentation/fb/framebuffer.txt)

discussion on phoronix (http://www.phoronix.com/forums/forum/linux-graphics-x-org-drivers/x-org-drm/41971-how-to-make-framebuffer-look-like-a-real-monitor)

xf86-video-dummy (http://cgit.freedesktop.org/xorg/driver/xf86-video-dummy)

I don't know if anything of this really is "state-of-the-art", or if there is some other way to do it in current systems/kernels, though.

Good luck!

Regards,

Philipp
