Hello all:
I have an ISA core that I am trying to port to PCI platform. This ISA core
uses host DMA channel to achive data transfer. I understand in PCI
environment the preferred way to do DMA is: a) need to be a PCI master. b)
provide all the DMA registers in the master.
Is there any other way to achive this, and be compatible with ISA DMA scheme
(i.e. using host DMA capability) in PCI? How does a PCI card signal the host
DMA controller to intiate DMA transfer? Can any of you shed some lights on
this issue. Can any of you share your experience of porting any ISA
functions with DMA to PCI?
Many thanks and best regards,
Khan.
