<refsect1><title>DESCRIPTION</title>
|
|
<para>
|
|
Linux kernel modules can provide services (called "symbols") for other
|
|
modules to use (using one of the EXPORT_SYMBOL variants in the code). If
|
|
a second module uses this symbol, that second module clearly depends on
|
|
the first module. These dependencies can get quite complex.
|
|
</para>
|
|
<para> <command>depmod</command> creates a list of module dependencies by
|
|
reading each module under
|
|
<filename>/lib/modules/</filename><replaceable>version</replaceable> and
|
|
determining what symbols it exports and what symbols it needs. By
|
|
default, this list is written to <filename>modules.dep</filename>, and a
|
|
binary hashed version named <filename>modules.dep.bin</filename>, in the
|
|
same directory. If filenames are given on the command line, only those
|
|
modules are examined (which is rarely useful unless all modules are
|
|
listed). <command>depmod</command> also creates a list of symbols
|
|
provided by modules in the file named
|
|
<filename>modules.symbols</filename> and its binary hashed version,
|
|
<filename>modules.symbols.bin</filename>. Finally,
|
|
<command>depmod</command> will output a file named
|
|
<filename>modules.devname</filename> if modules supply special device
|
|
names (devname) that should be populated in /dev on boot (by a utility
|
|
such as udev). </para> <para> If a <replaceable>version</replaceable> is
|
|
provided, then that kernel version's module directory is used rather than
|
|
the current kernel version (as returned by <command>uname -r</command>).

This option scans to see if any modules are newer than the

if not, it silently exits rather than regenerating the files.

<para>

If your modules are not currently in the (normal) directory
|
|
<filename>/lib/modules/</filename><replaceable>version</replaceable>,
|
|
but in a staging area, you can specify a
|
|
<replaceable>basedir</replaceable> which is prepended to the
|
|
directory name. This <replaceable>basedir</replaceable> is
|
|
stripped from the resulting <filename>modules.dep</filename> file,
|
|
so it is ready to be moved into the normal location. Use this
|
|
option if you are a distribution vendor who needs to pre-generate
|
|
the meta-data files rather than running depmod again later.

<para>
|
|
When combined with the <option>-F</option> option, this reports any
|
|
symbols which a module needs which are not supplied by other
|
|
modules or the kernel. Normally, any symbols not provided by
|
|
modules are assumed to be provided by the kernel (which should be
|
|
true in a perfect world), but this assumption can break especially
|
|
when additionally updated third party drivers are not correctly
|
|
installed or were built incorrectly.
