How to use kernel module?

Procedure Select a kernel module you want to load. The modules are located in the /lib/modules/$(uname -r)/kernel/<SUBSYSTEM>/ directory. Load the relevant kernel module: # modprobe <MODULE_NAME> modprobe <MODULE_NAME> Optionally, verify the relevant module was loaded: $ lsmod | grep <MODULE_NAME>

Where do I put kernel modules in Linux?

Build and kernel module the kernel dev bundle corresponding to the installed kernel. The kernel dev bundle contains the kernel headers, which are placed under /usr/lib/modules/$(uname -r)/build/include/ and are required to compile kernel modules.

How to load the kernel module?

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

How to use a kernel module?

To load a kernel module, use the insmod utility. This utility receives as a parameter the path to the *. ko file in which the module was compiled and linked. Unloading the module from the kernel is done using the rmmod command, which receives the module name as a parameter.

What is the purpose of 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.

What language are kernel modules written in?

The kernel is written in the C programming language [c-language]. More precisely, the kernel is typically compiled with gcc [gcc] under -std=gnu11 [gcc-c-dialect-options]: the GNU dialect of ISO C11.

Is the Linux kernel C or C++?

It might come as a surprise to many a new hand, but the Linux Kernel is written in C and not just as a passive preference - Linux is actively pro-C and anti-C++.

What programming languages are used in Linux kernel?

Most of the kernel code is written in C as supported by the GNU compiler collection (GCC) which has extensions beyond standard C. The code also contains assembly code for architecture-specific logic such as optimizing memory use and task execution.
