Advanced DMA

[carbonBased]

Hello all,

I'm curious as to whether anybody has any documentation on some of the later forms of DMA (ie, bus mastered, pci, etc, DMA).

I'm not even looking for programming info, per se, at this point, I'm just looking for capabilities (such as maximum bytes transfered, bus width, number of channels open at once, etc).

Cheers,
Jeff

PS: Of course, any programming info is greatly appreciated as well, as I will need it eventually anyway

I have the pcisig pci spec pdfs they make you charge for just to get hold of on my site. Not too sure if it can help in relation to dma but they're all there, PCI 2.0 specs. Might be useful.
