firewire — IEEE1394 High-performance Serial Bus

Authors

       The firewire driver was written by Katsushi Kobayashi and Hidetoshi Shimokawa for the FreeBSD project.

Bugs

       See fwohci(4) for security notes.

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
       https://wiki.freebsd.org/DebugWithDcons for details on how to setup debugging with firewire.

Synopsis

       To compile this driver into the kernel, place the following line in your kernel configuration file:

             devicefirewire

       Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

             firewire_load="YES"
