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 mas-
     ter,  isochronous	resource  manager  and	bus manager, are dynamically as-
     signed, 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 debugging with firewire.
