.Dd September 1, 2006 .Dt EBUS 4 sparc64 .Os .Sh NAME .Nm ebus .Nd "EBus controller and bus" .Sh SYNOPSIS .Cd "device ebus" .Sh DESCRIPTION The .Nm driver provides support for the EBus controller and bus found in most .Tn PCI based .Tn UltraSPARC systems. The .Tn EBus bus is designed to provide the ability to put .Tn ISA and traditional .Tn Intel style peripherals in a .Tn SPARC based system with a minimal amount of glue logic. In .Tn UltraSPARC systems it is implemented with either a PCIO or a PCIO-2 chip from .Tn Sun Microelectronics . The PCIO chip also implements a .Xr hme 4 compatible .Tn PCI network device. The PCIO-2 chip also implements a .Xr fwohci 4 compatible .Tn IEEE .Tn 1394 .Tn OHCI interface, a .Xr gem 4 compatible .Tn PCI network device and an .Xr ohci 4 compatible .Tn OHCI .Tn USB controller. The .Tn EBus has four DMA channels, similar to the DMA seen in the .Xr esp 4 .Tn SCSI DMA. .Sh SEE ALSO .Xr atkbdc 4 , .Xr auxio 4 , .Xr eeprom 4 , .Xr rtc 4 , .Xr scc 4 , .Xr snd_audiocs 4 , .Xr uart 4 .Rs .%Q "Sun Microelectronics" .%T "Peripheral Component Interconnect Input Output Controller" .%V "Part No.: 802-7837-01" .%D "March 1997" .%U "http://www.sun.com/oem/products/manuals/802-7837.pdf" .Re .Sh HISTORY The .Nm driver first appeared in .Nx 1.5 .
