EBUS(4) OpenBSD Programmer's Manual (SPARC64) EBUS(4)NAMEebus - 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.
OpenBSD provides support for the following devices:
audioce(4) SPARC64 EBus CS4231 audio device
auxio(4) SPARC64 auxiliary I/O
bbc(4) SPARC64 BootBus Controller
beeper(4) console annunciator
clock(4) Real-time clock
com(4) serial communications interface
comkbd(4) serial keyboard driver
comms(4) serial mouse driver
led(4) SPARC64 LED driver
lom(4) lights out management
lpt(4) parallel port driver
pcfiic(4) Phillips PCF8584 I2C controller
pckbc(4) PC (ISA) keyboard controller driver
pmc(4) power management controller
power(4) power button
sab(4) Infineon SAB82532 (ESCC2) serial communications driver
uperf(4) performance counters driver
wbsd(4) Winbond W83L518D/W83L519D SD memory card interface
