NAME
kldload —
load a file into the kernel
SYNOPSIS
kldload |
[-nqv] file ... |
DESCRIPTION
The kldload utility loads
file.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
.ko extension name is not mandatory when loading a
given module using kldload. It does not hurt to
specify it though.
If a bare filename is requested it will only be loaded if it is
found within the module path as defined by the sysctl
kern.module_path. To load a module from the current
directory it must be specified as a full or relative path. The
kldload utility will warn if a module is requested
as a bare filename and is present in the current directory.
The following options are available:
-n- Do not try to load module if already loaded.
-v- Be more verbose.
-q- Silence any extraneous warnings.
NOTES
The kernel security level settings may prevent a module from being loaded or unloaded by giving Operation not permitted.
FILES
- /boot/kernel
- directory containing loadable modules. Modules must have an extension of .ko.
EXIT STATUS
The kldload utility exits 0 on
success, and >0 if an error occurs.
EXAMPLES
To load by module name:
> kldload foo
To load by file name within the module path:
> kldload foo.ko
To load by relative path:
> kldload ./foo.ko
To load by full path:
> kldload /boot/kernel/foo.ko
AUTOMATICALLY LOADING MODULES
Some modules (pf, ipfw, ipf, etc.) may be automatically loaded at boot time when the corresponding rc.conf(5) statement is used. Modules may also be auto-loaded through their addition to loader.conf(5).
