Making a hardware driver for openGL

[Mr Pixel]

Does anyone have experience with this?
I'd suspect that you would get a softwareimplementation and replace software functions with hardware calls one at the time, but does anyone know what software basis this might be? Doing everything from scratch is a bit unrealistic, but since I have a useful piece of hardware I would like to se if I could accelerate certain functions with it.

The platform is linux, but knowledge from any platform would be interesting. I do not have previous experience with driver development.

You started by the hardest driver possible! I develop network drivers, and they are already complicated. A 3D VGA is almost certainly a unhuman task for a single person.

You can use SGI's Opensource Sample Implementation (http://oss.sgi.com/projects/ogl-sample/) or mesa (http://www.mesa3d.org/) .

Thanks, this was sort of the reply I was looking for. I was already looking at Mesa, but the reference implementation seems perhaps better suited for this purpose. I know it is ambitious but I'm not entirely alone on this project.
