firewire - IEEE1394 High-performance Serial Bus
To compile this driver into the kernel, place the following line in your
kernel configuration file:
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
FreeBSD provides machine-independent bus support and raw drivers for
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 manager, are
dynamically assigned, after bus reset is initiated. On the firewire bus,
every device is identified by an EUI 64 address.
fwe(4), fwip(4), fwohci(4), pci(4), sbp(4), eui64(5), fwcontrol(8),
The firewire driver first appeared in FreeBSD 5.0.
The firewire driver was written by Katsushi Kobayashi and Hidetoshi
Shimokawa for the FreeBSD project.
