The modload utility loads a kernel module specified by
the module parameter into the running system.
Modules are loaded from the default system module areas unless the
module parameter contains a path separator character
(‘/’).
The options to modload are as follows:
-b
var=boolean
- Pass the module a boolean property with the name
var. boolean may be either
true or false.
-d
var
- When used in conjunction with
-m, delete
var from the plist
specified.
-f
- Force the module to be loaded. When a module is loaded, the kernel checks
if the module is compatible with the running kernel and will refuse to
load modules that are potentially incompatible. This option disables
compatibility checks. Note: an incompatible module can
cause system instability, including data loss or corruption.
This option is also required for re-enabling a builtin module
that was disabled using
modunload(8).
-i
var=integer
- Pass the module an integer property with the name
var and integral value
integer.
-m
plist
- When used in conjunction with
-p, merge new
options with an existing property list contained in
plist.
-P
- This option tells the kernel not to load an associated property list.
-p
- Output a property list suitable for loading along with a module. When
using this option, you do not need to specify a module. Use
-m and -d to read and
modify an existing property list.
-s
var=string
- Pass the module a string property with the name var
and string value string.
The modload utility exits with a status of 0 on success
and with a nonzero status if an error occurs.
A modload utility appeared in NetBSD
0.9. The modload command was designed to be
similar in functionality to the corresponding command in SunOS 4.1.3.
modload was switched to the kernel object linker
module framework for NetBSD 5.0, derived from the same
framework in FreeBSD.
The original NetBSD implementation was written by
Terrence R. Lambert
<terry@cs.weber.edu>.
The switch to the kernel object linker module framework was by
Andrew Doran
<ad@NetBSD.org>.
