First make sure you know how to dump reg, i use a tools from Vladimir: http://volodya-project.sourceforge.net/hw_script.php Then i will send you latter(when i access the computer on which they are) my script which use hw_script to dump reg. Basicly i dump all reg before starting anythings (after boot), then i start xserver with fglrx and i dump all reg, then i start x with r300 and i dump all reg. I have done this several time, running different apps each time thus i have some change in dump (maybe i am wrong doing so). Then i look at what reg are always the same in some fglrx dump and same in r300 dump (after fglrx) and different in r300 dump (r300 dump without previously run fglrx). With that i get a list of reg that fglrx always set in the same way (and that are preserved) and r300 doesn't. But some of them are status reg and finding which register(s) are needed to set a particular status is painfull and boring, you have to write in other regs hoping to no lock the card (which often lock) and now i am dealing with all this regs (as i already tested all non-status reg, and i think i haven't missed one, i hope :)) If anyone have a better procedure to track differences btw radeon/r300 2d driver from xorg and fglrx (2d driver) ?
