Sounds good, but here's the catch, I would like to use Gallium to accelerate the whole windowing system.? I want our windowing system to use libGL for all rendering, so Gallium would basically be running on the video card with no windowing system standing in the way.

I guess the main question is, "Do I have to use the DRI/DRM drivers in order to use the current hardware pipes?" And the main answer is, "no, DRI/DRM is not required." r300, i915, and i965 use a batchbuffer technique, and the nvxx pipes map the ring buffer into userspace, but none of them really know or care about how that's set up by the winsys. Your first target should probably be getting softpipe to run. Softpipe is, as the name suggests, a pipe that does all of its rendering in software, and it can run on top of any winsys. Wikipedia tells me that you guys are POSIX and Unix-like, but not using Xorg for your windowing system, so you will probably need a state tracker for your windowing system too. ~ C.
