What is a Linux Kernel Module - a Big Picture

Learning Linux Kernel Programming is always fascinating and yet challenging. So generally you may tend to learn Kernel Module programming, since such a module can be dynamically plugged into running Linux Kernel. But this will lead to confusion, and many assume kernel source is mostly a collection of these modules. Which in reality is kind of true but not strictly.

Not just that, when we say Kernel Module, its a vaguely defined term. The term “Module” (as we know) is nothing but a collection of APIs, bunch of variables and associated data-structures. Which may or may not be a plugable kernel module.

If you ask me, I am a fan of wiring Linux Kernel Modules, which may not be necessarily a pluggable kernel module. It all boils down to the address space at which these modules function inside a monolithic Linux Kernel. Which is nothing but Linux Kernel’s address space. Hence here is my detailed multi-episode YouTube video series on Linux Kernel modules, a big picture and the significance of the Kernel’s address space in relationship to these modules.

I also conduct sessions/classes on Systems and Network Software Programming, Linux Kernel Programming and Architecture. If you are interested, click HERE for more details.
