I personaly dont know how the ATI architecture differs that a kernel module might be unnecesarry. Fglrx also uses a kernel module.
It has a completely programmable command processor Neat. I thought that idea had died with TIGA ( http://en.wikipedia.org/wiki/Texas_Instruments_Graphics_Architecture ) until i read about NVidia´s CUDA (http://en.wikipedia.org/wiki/CUDA ). (Tom's Hardware has a pretty good overview in this case), A link would be nice. and all memory accesses (from the hardware side) seem to be virtual, so it might have a MMU. As long as the command processor cannot be programmed from user space, this scenario can be made secure for complete user space programming. I have *no* idea ATM, whether this works with the current DRI architecture or not, so this is probably something for later improvements, but not for the beginning. A completely programmable GPU changes things a lot. ATI/AMD should really open their specs on this, this is not only interresting for a X-driver. Ever heard of coupling 4 SLI cards in a system without adding a output connector to any of them? ( http://www.heise.de/newsticker/meldung/91374 , article in german) Still, the best bang for the buck if single precision computational

I´ll invest a couple of hours now and then. Been a while since i last did low level gfx card stuff and 3D, but i hope i´ll be able to contribute a bit more than just some pci-ids.
Cool :) Thanks, but don't follow that road too far ATM. It'll be quite a while until we will see 3D docs. At least that's my estimation. Now i got a different hunch. But writing a compiler is nothing i have knowledge of.
