FIREWIRE(4)		    Kernel Interfaces Manual		   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"

DEPRECATION NOTICE
       The firewire driver is slated to	be removed prior to FreeBSD 16.0.

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 at-
       tached 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 dy-
       namically assigned, after bus reset is initiated.  On the firewire bus,
       every device is identified by an	EUI 64 address.

       Debugging over the firewire interface is	 possible  with	 the  dcons(4)
       driver.	  Please   see	 https://docs.freebsd.org/en/books/developers-
       handbook/kerneldebug/#kerneldebug-dcons for details on how to setup de-
       bugging with firewire.
