What is a Linux Kernel Module - a Big Picture ↗Saturday' 01-Jan-2022
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 not.
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
