Dynamic Kernel Module Support (Dkms) Is a Framework Used to Generate Linux Kernel Modules on the Fly by Loading and Unloading Modules According to the Kernel Version in Use.
This Is Useful When You Need to Install a Newer Kernel Module Than the One Provided in the Repository of Your Linux Distribution.
In This Tutorial, We Will Show You How to Install Dkms and Build a Kernel Module From Source on an Ubuntu 18.04 Server.
What Is Dkms?
Dkms Is a Dynamic Kernel Module Support Framework. It Allows for the Automatic Creation, Building, Installation and Activation of Kernel Modules.
This Is Especially Useful for Modules That Need to Be Built for Multiple Kernels, or for Modules That Are Updated Frequently (Such as Wireless Drivers).
Ubuntu Uses Dkms to Automatically Build and Install New Kernel Modules When Needed. This Process Is Triggered When You Install a New Kernel, or Update an Existing One.
Why Do We Need Dkms?
Dkms Is a System Which Will Automatically Recompile and Install Kernel Modules When a New Kernel Is Installed. This Is Useful for Cases Where Modules Are Updated Frequently, Such as With Virtualization Platforms or Wireless Drivers.
Dkms Can Be Used to Automatically Rebuild Modules for Any New Kernel Version, Without Having to Manually Re-Install or Re-Compile the Module Each Time.
This Makes It Much Easier to Keep Module Versions up to Date, and Can Be a Valuable Time-Saver for System Administrators Managing Multiple Systems.
How to Install Dkms in Ubuntu Vm?
One of the Advantages of Using a Virtual Machine Is That You Can Easily Install and Uninstall Different Software Packages Without Affecting the Host Operating System.
If You’re Using Ubuntu as Your Virtual Machine, You Can Use the Apt Package Manager to Install Dkms.
Dkms Is a Tool That Enables the Automatic Installation of Kernel Modules. This Is Useful for When You Need to Install a Custom Kernel Module, Such as for Virtual Machine Drivers.
To Install Dkms in Ubuntu Vm, Open a Terminal and Type:
$ Sudo Apt-Get Install Dkms
This Will Install Dkms and All Its Dependencies. Once Installed, You Can Use Dkms to Automatically Build and Install Kernel Modules.
How to Use Dkms in Ubuntu Vm?
If You Want to Use Dkms in Your Ubuntu Vm, You Need to Install the Dkms Package. This Can Be Done Using the Apt Package Manager:
Sudo Apt Install Dkms
Once the Package Is Installed, You Can Use Dkms to Manage Your Kernel Modules. For Example, to Add a New Kernel Module:
Sudo Dkms Add -M Mymodule -V 1.0
To Remove a Kernel Module:
Sudo Dkms Remove -M Mymodule -V 1.0 --All
In Conclusion, Installing Dkms in an Ubuntu Virtual Machine Is a Relatively Simple Process.
After Completing the Steps Outlined in This Guide, You Should Have a Working Dkms Installation That Can Be Used to Manage Kernel Modules on Your System. Do let us know your feedback.
What Is Dkms?
Dkms Is a Framework Designed to Allow Individual Kernel Modules to Be Upgraded, Repaired, or Uninstalled Dynamically on a Running System (That Is, Without Having to Reboot).
How Does DKMS Work?
Dkms Monitors All Installed Kernel Modules and Matches Them Against Precompiled Versions Stored in /Var/Lib/Dkms. If a Module Has Been Modified, Dkms Will Recompile and Install It Automatically.
What if I Need to Upgrade My Kernel?
No Problem! Just Install the New Kernel and Run ‘Sudo Dkms Autoinstall’. Dkms Will Automatically Rebuild and Install Any Out-Of-Date Modules.
What Distributions Does It Support?
Currently, Dkms Is Known to Work on Debian,Ubuntu,Fedora,Rhel,Suse,and Gentoo. However, It Should Be Relatively Easy to Port It to Other Distributions as Well.
