Great! This is really excellent, much needed work.
A few months ago someone called Honza Havlicek was working on a wiki
page to try and document the nVidia architecture, which he called
"Developer Guidebook". It's at:
I e-mailed Honza a few days ago to ask if he's still interested in
hacking on nouveau, but no reply yet. My hope is that we could work
together on this document to bring it up to being a complete and
accurate mid-level description of how we render with 3D.
I also found this document recently:
It's outdated, but the "Example: How to render a solid rectangle?"
section makes a lot of sense. Between Honza's description of the MMIO
registers and the functional descriptions at the URL above, I think we
could get to a point where we're able to explain how rendering works
to someone sufficiently interested. :)
