NAME
     fwohci — OHCI firewire chipset device driver

SYNOPSIS
     kldload firewire

     or

     device firewire

DESCRIPTION
     The fwohci driver provides support for PCI/CardBus firewire interface
     cards.  The driver supports the following IEEE 1394 OHCI chipsets.

     NEC uPD72861

     Texas Instruments TSB12LV{22,23,26}, TSB43{AA22,AB22/A}, PCI44{10A,50}

     Sony CX3022

     VIA VT6306

     Ricoh R5C552

SEE ALSO
     firewire(4), fwe(4), sbp(4), fwcontrol(8), kldload(8)

HISTORY
     The fwohci device driver first appeared in FreeBSD 5.0.

AUTHORS
     The fwohci device driver was written by Katsushi Kobayashi and Hidetoshi
     Shimokawa.

BUGS
     The driver allows physical access from any nodes on the bus by default.
     This means that any devices on the bus can read and modify any memory
     space which can be accessed by an IEEE 1394 OHCI chip.  It is allowed
     mostly for sbp(4) devices.	 This should be changed to allow it only for
     specific devices.	Anyway, FireWire is a bus and not expected to be con‐
     nected with un-trustable devices because a node can monitor all the traf‐
     fic.
