What can you do with kernel modules?

Kernel modules are pieces of code that can be loaded and unloaded into the kernel upon demand. They extend the functionality of the kernel without the need to reboot the system. A module can be configured as built-in or loadable.

How to compile and run your own kernel modules

  1. Modify the makefile by replacing every occurrence of helloWorld and kernelRead by the names of the modules you wish to create.
  2. compile the modules by running make in the directory where the modules reside.
  3. Now become superuser by typing.

How do I run a kernel module?

Loading a Module

  1. To load a kernel module, run modprobe module_name as root .
  2. By default, modprobe attempts to load the module from /lib/modules/kernel_version/kernel/drivers/ .
  3. Some modules have dependencies, which are other kernel modules that must be loaded before the module in question can be loaded.

How do I change kernel config?

To configure the kernel, change to /usr/src/linux and enter the command make config. Choose the features you want supported by the kernel. Usually, There are two or three options: y, n, or m. m means that this device will not be compiled directly into the kernel, but loaded as a module.

Edit the /etc/modules file and add the name of the module (without the . ko extension) on its own line. On boot, the kernel will try to load all the modules named in this file. Copy the module to a suitable folder in /lib/modules/`uname -r`/kernel/drivers .

Why should I compile my own kernel?

The advantages of compiling your own kernel include being able to tune the kernel to your specific hardware, and ending up with a smaller kernel. You may also need to compile your own kernel if the default kernel does not support some specific hardware you have.
