IEEE1394IF(4)           NetBSD Kernel Interfaces Manual          IEEE1394IF(4)


NAME

     ieee1394if -- IEEE1394 High-performance Serial Bus


SYNOPSIS

     ieee1394if* at fwohci?


DESCRIPTION

     NetBSD provides machine-independent bus support and raw drivers for
     IEEE1394 interfaces.

     The ieee1394if driver consists of two layers: the controller and the bus
     layer.  The controller attaches to a physical bus (like pci(4)).  The
     ieee1394if 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
     IEEE1394 bus.  The root node is dynamically assigned with a PHY device
     function.  Also, the other IEEE1394 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 ieee1394if
     bus, every device is identified by an EUI 64 address.

HISTORY

     The ieee1394if driver first appeared in FreeBSD 5.0, as firewire.  It was
     added to NetBSD 4.0 under its present name.


AUTHORS

     The ieee1394if driver was written by Katsushi Kobayashi and Hidetoshi
     Shimokawa for the FreeBSD project.  It was added to NetBSD 4.0 by
     KIYOHARA Takashi.
