SYNOPSIS

depinfo [options] [module|filename|alias]...

DESCRIPTION

Displays the full path to module and its dependencies. It also shows the full path to firmware.

OPTIONS

-t, --tree: Show dependencies between modules hierarchically;
-D, --no-deps: Don't show dependence;
-P, --no-prefix: Omit the prefix describing the type of file;
-M, --no-modules: Omit modules from the output;
-F, --no-firmware: Omit firmware from the output;
-B, --no-builtin: Omit builtin modules from the output;
-k, --set-version=VERSION: Use VERSION instead of `uname -r`;
-b, --base-dir=DIR: Use DIR as filesystem root for /lib/modules;
-f, --firmware-dir=DIR: Use DIR as colon-separated list of firmware directories (default: /lib/firmware/updates:/lib/firmware);
--use-blacklist: Apply blacklist commands in the configuration files.
-i, --input=FILE: Read names from FILE;
-V, --version: Show version of program and exit;
-h, --help: Show this text and exit.

EXAMPLE

To see module dependencies and required firmware:

# depinfo -k 5.11.0-rc6 -t b43
module /lib/modules/5.11.0-rc6/kernel/drivers/net/wireless/broadcom/b43/b43.ko.xz


   \_ firmware /lib/firmware/b43/ucode9.fw


   \_ firmware /lib/firmware/b43/ucode5.fw


   \_ firmware /lib/firmware/b43/ucode30_mimo.fw


   \_ firmware /lib/firmware/b43/ucode33_lcn40.fw


   \_ firmware /lib/firmware/b43/ucode29_mimo.fw


   \_ firmware /lib/firmware/b43/ucode26_mimo.fw


   \_ firmware /lib/firmware/b43/ucode25_mimo.fw


   \_ firmware /lib/firmware/b43/ucode25_lcn.fw


   \_ firmware /lib/firmware/b43/ucode24_lcn.fw


   \_ firmware /lib/firmware/b43/ucode16_mimo.fw


   \_ firmware /lib/firmware/b43/ucode16_lp.fw


   \_ firmware /lib/firmware/b43/ucode15.fw


   \_ firmware /lib/firmware/b43/ucode14.fw


   \_ firmware /lib/firmware/b43/ucode13.fw


   \_ firmware /lib/firmware/b43/ucode11.fw


   \_ module /lib/modules/5.11.0-rc6/kernel/net/mac80211/mac80211.ko.xz


      \_ module /lib/modules/5.11.0-rc6/kernel/net/wireless/cfg80211.ko.xz


         \_ module /lib/modules/5.11.0-rc6/kernel/net/rfkill/rfkill.ko.xz


      \_ module /lib/modules/5.11.0-rc6/kernel/lib/crypto/libarc4.ko.xz


   \_ module /lib/modules/5.11.0-rc6/kernel/drivers/bcma/bcma.ko.xz


   \_ module /lib/modules/5.11.0-rc6/kernel/lib/math/cordic.ko.xz

You can also get a simple list of modules:

# depnfo -k 5.11.0-rc6 -F b43
module /lib/modules/5.11.0-rc6/kernel/drivers/net/wireless/broadcom/b43/b43.ko.xz
module /lib/modules/5.11.0-rc6/kernel/net/mac80211/mac80211.ko.xz
module /lib/modules/5.11.0-rc6/kernel/net/wireless/cfg80211.ko.xz
module /lib/modules/5.11.0-rc6/kernel/net/rfkill/rfkill.ko.xz
module /lib/modules/5.11.0-rc6/kernel/lib/crypto/libarc4.ko.xz
module /lib/modules/5.11.0-rc6/kernel/drivers/bcma/bcma.ko.xz
module /lib/modules/5.11.0-rc6/kernel/lib/math/cordic.ko.xz

Some modules can be compiled into the kernel:

# depinfo -k 5.11.0-rc6 -F btrfs
module /lib/modules/5.11.0-rc6/kernel/fs/btrfs/btrfs.ko.xz
module /lib/modules/5.11.0-rc6/kernel/crypto/blake2b_generic.ko.xz
builtin sha256_generic
module /lib/modules/5.11.0-rc6/kernel/crypto/xxhash_generic.ko.xz
builtin crc32c_generic
module /lib/modules/5.11.0-rc6/kernel/lib/libcrc32c.ko.xz
builtin crc32c_generic
module /lib/modules/5.11.0-rc6/kernel/lib/raid6/raid6_pq.ko.xz
module /lib/modules/5.11.0-rc6/kernel/crypto/xor.ko.xz
