.Sh NAME
|
|
.Nm fwohci
|
|
.Nd OHCI FireWire chipset device driver
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following line in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device firewire"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
firewire_load="YES"
|
|
.Ed
|
|
.Pp
|
|
To disable physical access (see
|
|
.Sx BUGS
|
|
section for detail), put the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
hw.firewire.phydma_enable=0
|
|
.Ed
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver provides support for PCI/CardBus FireWire interface cards.
|

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
device driver first appeared in
|
|
.Fx 5.0 .
|
|
.Sh AUTHORS
|
|
.An -nosplit
|
|
The
|
|
.Nm
|
|
device driver was written by
|
|
.An Katsushi Kobayashi
|
|
and
|
|
.An Hidetoshi Shimokawa .
|
|
.Sh 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
|
|
.Xr sbp 4
|
|
devices.
|
|
This should be changed to allow it only for specific devices.
|
|
Anyway, FireWire is a bus and not expected to be connected with
|
|
un-trustable devices because a node can monitor all the traffic.
