NAME    [Toc]    [Back]

     EBus - introduction to SPARC EBus bus support and drivers

SYNOPSIS    [Toc]    [Back]

     ebus* at pci?

DESCRIPTION    [Toc]    [Back]

     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
     The EBus has four DMA channels, similar to the DMA  seen  in
the esp(4)
     SCSI DMA.
