NAME
iobus
- Device driver for the I/O bus
SYNOPSIS
iobus0 at root
DESCRIPTION
Systems supported by
NetBSD/acorn26
have a 16-bit I/O bus connected to the CPU bus by bi-directional buffers
managed by the IOC. The
iobus
driver provides support for this bus. All
NetBSD/acorn26
kernels need this driver.
On Archimedes systems, the only device attached at
iobus
is the IOC. While MEMC podules are physically
iobus
devices, they're logically treated as being attached to the IOC. On
machines with an IOEB, the Universal Peripheral Controller chip is also
attached at
.
