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"

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.
