NAME    [Toc]    [Back]

     firewire -- IEEE1394 High-performance Serial Bus

SYNOPSIS    [Toc]    [Back]

     kldload firewire

     or

     device firewire

     #include <dev/firewire/firewire.h>

DESCRIPTION    [Toc]    [Back]

     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.  And the additional driver 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 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 firewire bus,
     every device is identified with EUI 64 address.
