NAME<\/p>\n
depmod – Generate modules.dep and map files.<\/p>\n
SYNOPSIS<\/p>\n
depmod [-b basedir] [-e] [-E Module.symvers] [-F System.map] [-n]
\n[-v] [-A] [-P prefix] [-w] [version]<\/p>\n
depmod [-e] [-E Module.symvers] [-F System.map] [-m] [-n] [-v]
\n[-P prefix] [-w] [version] [filename…]<\/p>\n
DESCRIPTION<\/p>\n
Linux kernel modules can provide services (called “symbols”) for
\nother modules to use (using one of the EXPORT_SYMBOL variants in the
\ncode). If a second module uses this symbol, that second module
\nclearly depends on the first module. These dependencies can get quite
\ncomplex.<\/p>\n
depmod creates a list of module dependencies by reading each module
\nunder \/lib\/modules\/version and determining what symbols it exports
\nand what symbols it needs. By default, this list is written to
\nmodules.dep, and a binary hashed version named modules.dep.bin, in
\nthe same directory. If filenames are given on the command line, only
\nthose modules are examined (which is rarely useful unless all modules
\nare listed).\u00a0 depmod also creates a list of symbols provided by
\nmodules in the file named modules.symbols and its binary hashed
\nversion, modules.symbols.bin. Finally, depmod will output a file
\nnamed modules.devname if modules supply special device names
\n(devname) that should be populated in \/dev on boot (by a utility such
\nas systemd-tmpfiles).<\/p>\n
If a version is provided, then that kernel version’s module directory
\nis used rather than the current kernel version (as returned by uname
\n-r).<\/p>\n
OPTIONS<\/p>\n
-a, –all
\nProbe all modules. This option is enabled by default if no file
\nnames are given in the command-line.<\/p>\n
-A, –quick
\nThis option scans to see if any modules are newer than the
\nmodules.dep file before any work is done: if not, it silently
\nexits rather than regenerating the files.<\/p>\n
-b basedir, –basedir basedir
\nIf your modules are not currently in the (normal) directory
\n\/lib\/modules\/version, but in a staging area, you can specify a
\nbasedir which is prepended to the directory name. This basedir is
\nstripped from the resulting modules.dep file, so it is ready to
\nbe moved into the normal location. Use this option if you are a
\ndistribution vendor who needs to pre-generate the meta-data files
\nrather than running depmod again later.<\/p>\n
-C, –config file or directory
\nThis option overrides the default configuration directory at
\n\/etc\/depmod.d\/.<\/p>\n
-e, –errsyms
\nWhen combined with the -F option, this reports any symbols which
\na module needs which are not supplied by other modules or the
\nkernel. Normally, any symbols not provided by modules are assumed
\nto be provided by the kernel (which should be true in a perfect
\nworld), but this assumption can break especially when
\nadditionally updated third party drivers are not correctly
\ninstalled or were built incorrectly.<\/p>\n
-E, –symvers
\nWhen combined with the -e option, this reports any symbol
\nversions supplied by modules that do not match with the symbol
\nversions provided by the kernel in its Module.symvers. This
\noption is mutually incompatible with -F.<\/p>\n
-F, –filesyms System.map
\nSupplied with the System.map produced when the kernel was built,
\nthis allows the -e option to report unresolved symbols. This
\noption is mutually incompatible with -E.<\/p>\n
-h, –help
\nPrint the help message and exit.<\/p>\n
-n, –show, –dry-run
\nThis sends the resulting modules.dep and the various map files to
\nstandard output rather than writing them into the module
\ndirectory.<\/p>\n
-P
\nSome architectures prefix symbols with an extraneous character.
\nThis specifies a prefix character (for example ‘_’) to ignore.<\/p>\n
-v, –verbose
\nIn verbose mode, depmod will print (to stdout) all the symbols
\neach module depends on and the module’s file name which provides
\nthat symbol.<\/p>\n
-V, –version
\nShow version of program and exit. See below for caveats when run
\non older kernels.<\/p>\n
-w
\nWarn on duplicate dependencies, aliases, symbol versions, etc.<\/p>\n
