I'm in the process of gathering all the interesting information on the Utah-GLX project to the FAQ.
Their glossary (http://utah-glx.sourceforge.net/faq.html#AEN364) gives the definition of PIO, DMA and Pseudo DMA. The PIO definition presented there raises no polemics but I don't see what's different between Pseudo DMA and plain DMA. (It seems that their concept of plain DMA is in fact MMIO since no reference to MMIO is given there.) Could someone of the 3D gurus enlighten this question? More specifically, what is "pseudo DMA" and what is the relationship between DMA and the PIO and MMIO modes?
