I figured my first steps would be to try and reproduce the radeonfb driver to change the resolution, and go from there. Up until now I've been only developing graphics applications, so alot of these things are new to me - pixel clocks, horizontal timings, PLL, MTRR etc.etc.... it's all quite overwhelming. I've been reading as much as I can, but there are still big gaps in my understanding - how did everyone else get up to speed in this area? My main problem is that although it's fairly easy to follow the radeonfb source and the fb in general, when it comes to what register does what I'm completely lost. Did the people who wrote the driver have technical specs from ATI telling them which did what? Are the specs openly available, only under NDA, or not at all?! I'd really appreciate any tips anyone could give me on where I should be looking.
