EBUS(4) BSD Kernel Interfaces Manual EBUS(4)NAME
EBus — introduction to SPARC EBus bus support and drivers
SYNOPSIS
ebus* at pci?
DESCRIPTION
The EBus bus is designed to provide the ability to put ISA and tradi‐
tional 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.
