EBus - introduction to SPARC EBus bus support and drivers
ebus* at pci?
The EBus bus is designed to provide the ability to put ISA
and traditional
Intel-style peripherals in a SPARC based system with a
minimal amount
of glue logic. Typically, it is implemented in the PCIO IC
from SME,
which also implements a hme(4) compatible PCI network device
(`network').
The EBus has four DMA channels, similar to the DMA seen in
the esp(4)
SCSI DMA.
