If you have a decent understanding of render and how xorg drivers are organized you should be ok. the other drivers with exa and render support are a good model of comparison. > understand that there are no specs for the X300 (at least on the 3D > side, is the 2D engine documented?), so does most work come from reverse 2D specs used to be available via NDA from ATI, but I doubt you'll have much luck getting them. that said, you really don't need them as the radeon driver is well documented and pretty clear. All radeons up through the r4xx models have the same basic display engine (even rage128 for that matter). > engineering the ATI binary driver?

I look forward to hopefully working with you > guys in the future (exams end next Thursday :( ) Thanks for your time, there should be enough information in the r300 mesa 3d driver to implement exa render accel. basically just look at how it's done for r100 and r200 and fill in a new section for r300.
