.Cd "ebus* at pci?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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
|
|
.Xr hme 4
|
|
compatible PCI network device
|
|
.Pf ( Ql network ) .
|
|
The
|
|
.Nm
|
|
has four DMA channels, similar to the DMA seen in the
|
|
.Xr esp 4
|
|
.\" XXX: prevent SC-SI
|
|

|
|
SCSI DMA.
