.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
program works with the
|
|
.Xr drvctl 4
|
|
pseudo-driver, and allows to rescan busses and to detach
|
|
drivers from devices.
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width 123456
|
|
.It Fl r
|
|
Rescan the bus given by the
|
|
.Ar busdevice
|
|
argument.
|
|
The scan range can be restricted by an optional
|
|
.Ar locator
|
|
list.
|
|
.It Fl a
|
|
Give the interface attribute where children are to be
|
|
attached to (and which defines the interpretation of
|
|
the locator information).
|
|
This will only be needed in rare cases where the bus
|
|
has multiple attributes.
|
|
.It Fl d
|
|
Detach the device driver from the device given by the
|
|
.Ar device
|
|
argument.
|
|
.It Fl p
|
|
Get the properties for the device specified by the
|
|
.Ar device
|
|
argument.
|
|
The properties are displayed as an XML property list.

|
.Sh BUGS
|
|
Currently, there is no good way to get information about locator
|
|
lengths and default values (which is present at kernel configuration
|
|
time) out of a running kernel.
|
|
Thus the locator handling is less intelligent as it could be.
