NAME #

ebus - introduction to SPARC EBus bus support

SYNOPSIS #

ebus* at pci? ebus* at mainbus0

DESCRIPTION #

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 an hme(4) compatible PCI network device (’network’). The ebus has four DMA channels, similar to the DMA seen in the esp(4) SCSI DMA.
