NAME
depinfo - shows module dependencies
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.
--missing-firmware Show firmware that could not be found.
-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
To find out what firmware could not be found for the kernel modules:
# depinfo --missing-firmware rtlwifi module /lib/modules/6.15.5-gentoo-dist/kernel/drivers/net/wireless/realtek/rtlwifi/rtlwifi.ko
\_ module /lib/modules/6.15.5-gentoo-dist/kernel/net/wireless/cfg80211.ko
\_ missing-firmware regulatory.db
\_ missing-firmware regulatory.db
\_ missing-firmware regulatory.db.p7s
\_ missing-firmware regulatory.db.p7s
\_ module /lib/modules/6.15.5-gentoo-dist/kernel/net/rfkill/rfkill.ko
\_ module /lib/modules/6.15.5-gentoo-dist/kernel/net/mac80211/mac80211.ko
\_ module /lib/modules/6.15.5-gentoo-dist/kernel/lib/crypto/libarc4.ko
