Over the past few days, some of our readers have encountered an error while unloading a Linux kernel driver. This problem can arise for several reasons. Let’s discuss some of them below.
A kernel module is a program that can be installed or unloaded from any type of kernel as needed without the need to recompile the device (kernel) or platform reboothandles, and is designed to provide all the functions of the kernel. … General
In software, modules are more or less similar to plugins for software like WordPress. Plugins provide the ability to extend the functionality of a software without having to create huge software that combines all the functionality in one package. If typical new features are required, they need to be added in new software releases.
Even without modules, this kernel would have to be built individually, with functionality built right into the entire kernel image. This will mean developing larger kernels, and sysadmins may have to recompile the kernel almost every time new functionality is needed.
A simple example of a module is usually a device driver that provides kernel access to an electronic component / device attached to the system.

List Of All Loaded Linux Kernel Modules
How do I unload a driver in Linux?
Typically, use the modprobe -r command to unload the hxge driver at any time without actually uninstalling the driver. Number #> lsmod | grep hxge hxge 168784 naught host #> modprobe -r hxge #> lsmod | grep hxge #>Uninstall the hxge driver.
On Linux, all modules end with this
.ko extension and are usually auto-filled, since the detected hardware is no doubt recognized at system startup. However, a program administrator can control multiple modules using commands.
To list all currently available modules on Linux, we can use the (list lsmod modules) command, which reads the contents of / proc / modules as an example.

How To Load And Unload (uninstall) Kernel Modules In Linux
How do you load and unload a kernel module in Linux?
To load a kernel module, run modprobe module_name as root.Modprobe implicitly tries to load a segment from / lib / modules / kernel_version / kernel / drivers /.Some modules create dependencies, which are further kernel adventures that must be loaded before loading the new module in question.
To load a specific kernel module,we can use the special command insmod (insert module). We need to provide the full trajectory of the module. The command on this page inserts the speedtep-lib.ko module.
# insmod /lib/modules/4.4.0-21-generic/kernel/drivers/cpufreq/speedstep-lib.ko
To unload a kernel component, we use the rmmod (remove module) command. In the following example, the SpeedStep-lib.ko module has been unzipped or removed.
# rmmod /lib/modules/4.4.0-21-generic/kernel/drivers/cpufreq/speedstep-lib.ko
How To Manage Kernel Modules Using The Modprobe Command
modprobe is a qualified command for listing, inserting and removing modules, including the kernel. It looks in the modules directory of website / lib / modules / $ (uname -r) for all web designs and related files, but excludes the alternate design files in the /etc/modprobe.d directory.
You don’t need absolute module leadership here; This is the whole advantage of using modprobe over the previous commands.
# modprobe SpeedStep-lib
# modprobe -b speedtep-lib
Note. In modprobe, the auto underline is constantly being converted, so there is a number difference between
- after entering the module name.
Other important All information and use cases can be found on the “Thanks to modprobe” manual page.

How do I remove a module from a kernel?
To unload a kernel module, we use the rmmod (remove module) command. In the following example, Speedstep-Lib is unloaded or trimmed. to the module.

Which command can both load and unload kernel modules?
You can either explicitly load and sell Linux kernel modules using the insmod and rmmod commands, or each kernel may need to load a new kernel daemon (kerneld) in order for the modules to be unloaded as-is. Usually needed.
