31.Sh NAME

33.Nd load a file into the kernel
34.Sh SYNOPSIS
35.Nm
36.Op Fl qv
37.Ar
38.Sh DESCRIPTION
39The
40.Nm
41utility loads
42.Ar file Ns Pa .ko
43into the kernel using the kernel linker.
44Note that if multiple modules are specified then an attempt will
45be made to load them all, even if some fail.
46The
47.Pa .ko
48extension name is not mandatory when loading a given module
49using
50.Nm .
51It does not hurt to specify it though.
52.Pp
53If a bare filename is requested it will only be loaded if it is found within
54the module path as defined by the sysctl
55.Va kern.module_path .
56To load a module from the current directory it must be specified as a full or
57relative path.
58The
59.Nm
60utility will warn if a module is requested as a bare filename and is present
61in the current directory.
62.Pp
63The following options are available:
64.Bl -tag -width indent
65.It Fl v
66Be more verbose.
67.It Fl q
68Silence any extraneous warnings.
69.El
70.Sh NOTES
71.Pp
72The kernel security level settings may prevent a module from being
73loaded or unloaded by giving
74.Em "Operation not permitted" .
75.Sh FILES
76.Bl -tag -width /boot/kernel -compact
77.It Pa /boot/kernel
78directory containing loadable modules.
79Modules must have an extension of
80.Pa .ko .
81.El
82.Sh EXIT STATUS
83.Ex -std
84.Sh EXAMPLES
85To load by module name:
86.Bd -literal -offset indent
87\*[Gt] kldload foo
88.Ed
89.Pp
90To load by file name within the module path:
91.Bd -literal -offset indent
92\*[Gt] kldload foo.ko
93.Ed
94.Pp
95To load by relative path:
96.Bd -literal -offset indent
97\*[Gt] kldload ./foo.ko
98.Ed
99.Pp
100To load by full path:
101.Bd -literal -offset indent
102\*[Gt] kldload /boot/kernel/foo.ko
103.Ed
104.Sh AUTOMATICALLY LOADING MODULES
105Some modules (pf, ipfw, ipf, etc.) may be automatically loaded at boot
106time when the corresponding
107.Xr rc.conf 5
108statement is used.
109Modules may also be auto-loaded through their addition to
110.Xr loader.conf 5 .
