How can I get started with kernel development?

To get into kernel development, you’ll need a few tools. Make sure you have the OSDev wiki, a text editor, and a freestanding compiler, like GCC, set up. It’s also important to understand the architecture you’re targeting—you'll need that knowledge to boot up your kernel initially. 'Three Easy Pieces' is a decent resource, although it focuses on user space quickly. Plus, there are guides that use Rust or educational OS codebases from universities you could check out.

Many beginners start with the Linux kernel after learning C and picking up some basic OS concepts. You might want to begin by writing simple kernel modules before tackling the core. The Linux kernel source and documentation are essential, and there are some great books and blogs out there that can help you.

Before we dive in, can you share a bit about what you already know regarding operating systems? That way, I can better guide you. There’s actually a ton of resources available for developing operating systems from scratch. I recommend checking out the OSDev wiki and the MINIX 3 documentation to get started. Just a heads-up, starting with the current Linux kernel might be overwhelming since it’s pretty big; an older kernel could be a better choice.

Honestly, there's a lot of content available for kernel development! I'd suggest starting with honing your research skills—that will help you find what you need more effectively.
