Hi,
I am planning to use both Packet based DMA and Common buffer DMA (for
Write and Read resp.) for my Busmaster PCI device.
My doubt is whether I can use a single ADAPTER_OBJECT for this if both
DMAs are expected to run simultaneously?
I understand that if both DMAs are implemented as Packet based DMAs, then
I need to create another ADAPTER_OBJECT by creating dummy device objects
(as suggested in Walter Oney’s book). But is it necessary when one of the
DMAs is Common buffer DMA?
Any response will be appreciated.
Thanks,
Regards,
Abhijit
