38.Sh NAME
39.Nm fwohci
40.Nd OHCI FireWire chipset device driver
41.Sh SYNOPSIS
42To compile this driver into the kernel,
43place the following line in your
44kernel configuration file:
45.Bd -ragged -offset indent
46.Cd "device firewire"
47.Ed
48.Pp
49Alternatively, to load the driver as a
50module at boot time, place the following line in
51.Xr loader.conf 5 :
52.Bd -literal -offset indent
53firewire_load="YES"
54.Ed
55.Pp
56To disable physical access (see
57.Sx BUGS
58section for detail), put the following line in
59.Xr loader.conf 5 :
60.Bd -literal -offset indent
61hw.firewire.phydma_enable=0
62.Ed
63.Sh HARDWARE
64The
65.Nm
66driver provides support for PCI/CardBus FireWire interface cards.
67The driver supports the following IEEE 1394 OHCI chipsets:

134.Sh HISTORY
135The
136.Nm
137device driver first appeared in
138.Fx 5.0 .
139.Sh AUTHORS
140.An -nosplit
141The
142.Nm
143device driver was written by
144.An Katsushi Kobayashi
145and
146.An Hidetoshi Shimokawa .
147.Sh BUGS
148The driver allows physical access from any nodes on the bus by default.
149This means that any devices on the bus can read and modify any memory space
150which can be accessed by an IEEE 1394 OHCI chip.
151It is allowed mostly for
152.Xr sbp 4
153devices.
154This should be changed to allow it only for specific devices.
155Anyway, FireWire is a bus and not expected to be connected with
156un-trustable devices because a node can monitor all the traffic.
