35.Dt FIREWIRE 4
36.Os
37.Sh NAME
38.Nm firewire
39.Nd IEEE1394 High-performance Serial Bus
40.Sh SYNOPSIS
41To compile this driver into the kernel,
42place the following line in your
43kernel configuration file:
44.Bd -ragged -offset indent
45.Cd "device firewire"
46.Ed
47.Pp
48Alternatively, to load the driver as a
49module at boot time, place the following line in
50.Xr loader.conf 5 :
51.Bd -literal -offset indent
52firewire_load="YES"
53.Ed
54.Sh DESCRIPTION
55.Fx
56provides machine-independent bus support and raw drivers for
57.Nm
58interfaces.
59.Pp
60The
61.Nm
62driver consists of two layers: the controller and the
63bus layer.
64The controller attaches to a physical bus
65(like
66.Xr pci 4 ) .
67The
68.Nm
69bus attaches to the controller.
70Additional drivers can be attached to the bus.
71.Pp
72Up to 63 devices, including the host itself, can be attached to
73a
74.Nm
75bus.
76The root node is dynamically assigned with a PHY device function.
77Also, the other
78.Nm
79bus specific parameters,
80e.g., node ID, cycle master, isochronous resource manager and bus
81manager, are dynamically assigned, after bus reset is initiated.
82On the
83.Nm
84bus, every device is identified by an EUI 64 address.
