firewire(4)

NAME

firewire - IEEE1394 High-performance Serial Bus

SYNOPSIS

To compile this driver into the kernel, place the  following
line in your
kernel configuration file:
      device firewire
Alternatively,  to load the driver as a module at boot time,
place the
following line in loader.conf(5):
      firewire_load="YES"

DESCRIPTION

FreeBSD provides machine-independent bus support and raw
drivers for
firewire interfaces.
The firewire driver consists of two layers: the controller
and the bus
layer. The controller attaches to a physical bus (like
pci(4)). The
firewire 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
firewire bus. The root node is dynamically assigned with a
PHY device
function. Also, the other firewire bus specific parameters,
e.g., node
ID, cycle master, isochronous resource manager and bus man
ager, are
dynamically assigned, after bus reset is initiated. On the
firewire bus,
every device is identified by an EUI 64 address.
