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.
