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.
