Linux kernel modules

Introduction to a kernel module

Some of the functional modularity is the idea of micro-core, where the modularity is mainly to reduce the size of the kernel, and depending on the host can allow users to customize the loading module, to facilitate the less common hardware driver to get loaded without wasting space

The directory for general storage modules is/lib/modules/$ (uname R)/kernel

Two commands of the management module

Lsmod: Lists the currently loaded modules, containing dependencies

Modinfo mod_name: Display Module details

Manually loading the module, there may be a dependency limit

Insmod/module/about/path understood as insert MODULE, you need to specify the path

Rmmod mod_name Delete a module

Automatic Processing dependencies:

Modprobe mod_name automatically loads a module, ensuring that the service script exists in the/etc/init.d/* corresponding directory

modprobe r mod_name Delete a module
