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):
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 manager, are
dynamically assigned, after bus reset is initiated. On the
firewire
bus, every device is identified by
an EUI 64 address.
Debugging over the firewire interace is possible with the
dcons(4) driver. Please see
http://wiki.freebsd.org/DebugWithDcons for
details on how to setup debugging with firewire.

HISTORY¶
The
firewire
driver first appeared in
FreeBSD 5.0.
