.Sh NAME
.Nm firewire
.Nd IEEE1394 High-performance Serial Bus
.Sh SYNOPSIS
.Cd "device firewire"
.Pp
.In dev/firewire/firewire.h
.Sh DESCRIPTION
.Fx
provides machine-independent bus support and row drivers for
.Tn firewire
interfaces.
.Pp
The
.Nm
driver consists of two layers: the controller and the
bus layer.
The controller attaches to a physical bus
(like
.Xr pci 4 ) .
The
.Tn firewire
bus attaches to the controller. And the additional driver can be
attached to the bus.
.Pp
Up to 63 devices, including the host itself, can be attached to
a firewire bus. The root node is dynamically assigned with PHY
device function. Also, the other firewire bus specific parameters
e.g. node id, cycle master, isochronous resource manager and bus
manager, are dynamically assigned, after bus rest is initiated.
On firewire bus, every device is identified with EUI 64 address.

for the
.Nx
project.
