NAME
modinfo - display information about loaded kernel modules
SYNOPSIS
/usr/sbin/modinfo [-aw] [-c | [-i module] [-pP] [-o field[,...]]]
DESCRIPTION
The modinfo utility displays information about the loaded modules. The
format of the information is as follows:
ID LOADADDR SIZE INFO REV NAMEDESC
where ID is the decimal module Id, LOADADDR is the starting text
address in hexadecimal for privileged users but '--' for unprivileged
users. SIZE is the size of text, data, and bss in hexadecimal bytes,
INFO is module specific information, REV is the revision of the load‐
able modules system, and NAMEDESC is the filename and description of
the module.
The module specific information is the block and character major num‐
bers for drivers, the system call number for system calls, and unspeci‐
fied for other module types.
OPTIONS
The following options are supported:
-c Displays the number of times the module was loaded
and the module's current state. This option includes
-a and cannot be used with -i, -o, -p, or -P.
-i module Displays information about the specified module only.
If 'module' starts with a digit then it is inter‐
preted as a decimal module Id, otherwise it is inter‐
preted as a module name. A decimal module Id may
change across a reboot.
-o field[,...] A case-insensitive, comma-separated list of output
fields to display. The field name must be one of the
fields listed below, or the special value all to dis‐
play all fields. The following fields are supported:
id, loadaddr, size, info, rev, path, name, desc,
namedesc, loadcnt, state, all. For a loaded module,
'path' is the actual path that the kernel used when
loading the module is displayed. For a module that is
not loaded the path that the kernel would use to load
the module is derived. Output may not match the bind‐
ing which occurs if software is added or removed from
the system. Such changes may cause a different path
to be used when the module is next loaded. If mod‐
info(8) is unable to determine where the module would
be loaded from, it prints a question mark in front of
the path. This option implicitly includes -w.
-p Displays using a stable machine-parsable format. The
-o option is required with this option. See "Parsable
Output Format" below.
-P Only displays the path and header information. It's a
alias for '-p -o path'.
-a Displays information for all modules, including ones
not currently loaded.
-w Do not truncate module information at 80 characters.
Parseable Output Format
If more than one field is listed for the -o option, the output format
is one or more lines of colon (:) delimited fields. The output includes
only those fields requested by means of the -o option, in the order
requested. When you request multiple fields, any literal colon charac‐
ters are escaped by a backslash (\) before being output. Similarly,
literal backslash characters are also escaped (\\). This escape format
is parsable by using shell read(1) functions with the IFS environment
variable set as IFS=:.
Note that escaping is not done when you request only a single field.
EXAMPLES
Example 1 Displaying the Status of a Module
The following example displays the status of module 3:
example% modinfo -i 3
ID LOADADDR SIZE INFO REV NAMEDESC
3 fffffffffbdcf000 7410 1 1 specfs (filesystem for specfs)
example% modinfo -i specfs
ID LOADADDR SIZE INFO REV NAMEDESC
3 fffffffffbdcf000 7410 1 1 specfs (filesystem for specfs)
Example 2 Displaying the Status of Kernel Modules
The following example displays the status of some kernel modules:
example% modinfo
ID LOADADDR SIZE INFO REV NAMEDESC
0 fffffffffb800000 3b3cb4 -- 0 unix ()
1 fffffffffb9f8208 43e068 -- 0 genunix ()
3 fffffffffbdcf000 7410 1 1 specfs (filesystem for specfs)
4 fffffffffbdd6370 5d80 3 1 fifofs (filesystem for fifo)
5 fffffffff80b4000 267c8 53 1 dtrace (Dynamic Tracing)
6 fffffffffbddc038 9608 16 1 devfs (devices filesystem)
7 fffffffffbde53f0 21830 17 1 dev (/dev filesystem)
8 fffffffffbe064e8 8078 -- 1 dls (Data-Link Services)
9 fffffffffbe0e248 4c908 -- 1 mac (MAC Services)
10 fffffffffbe59968 25c20 5 1 procfs (filesystem for proc)
Example 3 Using the -c Option
Using the modinfo command with the -c option displays the number of
instances of the module loaded and the module's current state.
example% modinfo -c
ID LOADCNT NAME STATE
0 1 unix LOADED/INSTALLED
1 1 genunix LOADED/INSTALLED
2 0 cl_bootstrap UNLOADED/UNINSTALLED
3 1 specfs LOADED/INSTALLED
4 1 fifofs LOADED/INSTALLED
5 1 dtrace LOADED/INSTALLED
6 1 devfs LOADED/INSTALLED
7 1 dev LOADED/INSTALLED
8 1 dls LOADED/INSTALLED
9 1 mac LOADED/INSTALLED
10 1 procfs LOADED/INSTALLED
11 0 lbl_edition UNLOADED/UNINSTALLED
Example 4 Using the -o and -p Options
Using the modinfo command with the -o and -p option displays user-spec‐
ified fields and in machine-parsable format.
example% modinfo -o id,desc,path -i specfs
ID DESC PATH
3 filesystem for specfs /kernel/fs/amd64/specfs
example% modinfo -o id,desc,path -i specfs -p
3:filesystem for specfs:/kernel/fs/amd64/specfs
