NAME
ieee1394if —
IEEE1394 High-performance Serial
Bus
SYNOPSIS
ieee1394if* at fwohci?
DESCRIPTION
NetBSD provides machine-independent bus support and raw drivers for IEEE1394 interfaces.The ieee1394if driver consists of two
layers: the controller and the bus layer. The controller attaches to a
physical bus (like pci(4)). The ieee1394if bus attaches
to the controller. Additional drivers can be attached to the bus.
Up to 63 devices, including the host itself, can be attached to a
IEEE1394 bus. The root node is dynamically assigned with a PHY device
function. Also, the other IEEE1394 bus specific parameters, e.g., node ID,
cycle master, isochronous resource manager and bus manager, are dynamically
assigned, after bus reset is initiated. On the
ieee1394if bus, every device is identified by an EUI
64 address.
