Hello,
I have a PCI device that cannot be a PCI bus master (only a
PCI target). For some reason it has a DMA controller. Since it can't be
a bus master I can't initiate DMA transfers from this PCI device to
system RAM.
My question is, can we use the motherboard's DMA controller to perform
this transfer? In some of the documents that I got in the web
(http://www.pcguide.com/ref/mbsys/res/dma/func.htm), it is mentioned
that the 8237 DMA controller that comes with standard motherboard
chipsets, can only be used for DMA transfers over the ISA bus.
Any comments are welcome.
Regards,
-Romit
