|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility loads
|
|
.Ar file Ns Pa .ko
|
|
into the kernel using the kernel linker.
|
|
Note that if multiple modules are specified then an attempt will
|
|
be made to load them all, even if some fail.
|
|
The
|
|
.Pa .ko
|
|
extension name is not mandatory when loading a given module
|
|
using
|
|
.Nm .
|
|
It does not hurt to specify it though.
|
|
.Pp
|
|
If a bare filename is requested it will only be loaded if it is found within
|
|
the module path as defined by the sysctl
|
|
.Va kern.module_path .
|
|
To load a module from the current directory it must be specified as a full or
|
|
relative path.
|
|
The
|
|
.Nm
|
|
utility will warn if a module is requested as a bare filename and is present
|
|
in the current directory.
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width indent
|
|
.It Fl n
|
|
Do not try to load module if already loaded.
|
|
.It Fl v
|
|
Be more verbose.
|
|
.It Fl q
|
|
Silence any extraneous warnings.
|
|
.El
|
|
.Sh NOTES
|
|
The kernel security level settings may prevent a module from being
|
|
loaded or unloaded by giving
|
|
.Em "Operation not permitted" .
|
|
.Sh FILES
|
|
.Bl -tag -width /boot/kernel -compact
|
|
.It Pa /boot/kernel
|
|
directory containing loadable modules.
|
|
Modules must have an extension of
|
|
.Pa .ko .

.Sh EXAMPLES
|

|
.Bd -literal -offset indent
|
|
\*[Gt] kldload foo
|
|
.Ed
|
|
.Pp
|
|
To load by file name within the module path:
|
|
.Bd -literal -offset indent
|
|
\*[Gt] kldload foo.ko
|
|
.Ed
|
|
.Pp
|
|
To load by relative path:
|
|
.Bd -literal -offset indent

.Pp
|
|
To load by full path:

\*[Gt] kldload /boot/kernel/foo.ko

|
.Sh AUTOMATICALLY LOADING MODULES
|
|
Some modules (pf, ipfw, ipf, etc.) may be automatically loaded at boot
|
|
time when the corresponding
|
|
.Xr rc.conf 5
|
|
statement is used.
|
|
Modules may also be auto-loaded through their addition to
|
|
.Xr loader.conf 5 .
