Me and Leif did it for the Mach64 once and I already gave a roadmap to how proceed more than once in this list. This is one [the most recent I think] I could find: http://marc.theaimsgroup.com/?t=101850699700001&r=1&w=2 The FAQ has been re-organized since and the "Mesa Internals" notes can be found on: http://dri.sourceforge.net/doc/faq/implementation.html#mesa-internals Another thing which I didn't explain enough is how to base on an existing driver. For exemplification I'll pretend the SIS is being updated, and the updates are being based on the R128 driver. You basically need to have 4 reference trees in your work dir: (a)SIS from recent trunk (c) R128 from ancient trunk (Mesa 3.4) (Mesa 3.4) || | \/ v (b)sis-0-0-?-branch <= (d) R128 from recent trunk Then one mimics from (a)->(b) the changes one sees in (c)->(d), by copying'n'pasting either from (a) or from (d) into (b), as appropriate. Using a visual diff tool (such as xxdiff) helps considerably this task. Care to notice that it's not necessary to have a deep understanding of the code - heck, at the time I admitedly had none! It's more like a visual puzzle. Actually is very similar to a jigsaw puzzle: it helps to have the full picture but it's not needed, as long as one keeps connecting the puzzle pieces one by one it's deemed to succeed. I hope this helps any caring sole for these old drivers to be more confident about this task.
