Do not know how to use linux's depmod command to generate module mapping files? In fact, it is not difficult to solve this problem. Let the editor take you to learn how to solve it. I hope you will gain a lot after reading this article.

The depmod command can generate a mapping file that the module depends on. When building an embedded system, this command is needed to generate the corresponding file. The depmod command supports kernel version "2.5.48" and older kernel uses the instruction "depmod.old".

Syntax format: depmod [parameters]

Common parameters:

-an analyze all available modules-b specify kernel module directory-e output symbols that cannot be referenced-F provides system.map files generated at kernel compilation-n print various kernel mapping files to standard output-A fast mode

Reference example

Show available modules:

[root@linuxcool] # depmod-a

List the modules that are mounted but not available:

[root@linuxcool] # depmod-e

List the dependencies of all modules, but only output them:

[root@linuxcool] # depmod-n Thank you for reading this article carefully. I hope the editor can share the contents of the mapping file of the module generated by linux's depmod command to help everyone. At the same time, I also hope that you can support us, pay attention to the industry information channel, and find out if you encounter problems. Detailed solutions are waiting for you to learn!
