[Back after a long period of pure driver work]
What are you really asking for? A documentation on the FX driver (there is
lots of stuff in there that I wrote/reworked, but at least as much which I
don't really have much background in), or a guide for how to write a modern
Mesa driver?
If you want to write an optimized driver, I'd suggest looking at either the
MGA or better still the i810 driver, either from the Utah GLX or DRI
repositories on sourceforge - these are both drivers which talk directly to
the hardware without an intervening abstraction layer like glide. Despite
this, they are both simpler and 'saner' than the current fx driver which has
grown a lot of complexity over the years.
