GSoC Raspberry Pi Graphics project

[Brian Schnepp <stebor2jr%gmail.com@localhost>]

Hi everyone,

I've just recently submitted my proposal for implementing this project
for this year's Google Summer of Code. My proposal specifically
suggests reimplementing the Linux vc4 driver for the NetBSD kernel, so
it uses the same DRM interfaces as the existing nouveau and amdgpu
ports, but without sharing any actual code from the vc4 driver which
is under the GPL license. Ideally, this should be seen as compatible
under Mesa, so existing GLES programs should be able to use it. In
addition to this, some DeviceTree code for the Pi needs to be added.

I'd be very happy to write a GPU driver, but out of curiosity, I would
like to know if there might be a different way to implement this that
I just haven't seen yet, like if there was a way to shim the driver to
userspace and keep the original GPLed vc4 driver out of the kernel
that way, and just have it sent signals or something like that, or if
there is some other way to do this as well. I'd also like suggestions
on this project in general, and would like to make sure this method of
supporting the VC4 GPU sounds good overall.

Thanks,
Brian
