i know... i know... this isn't what someone should ask, but i would really appreciate some tips or any resources outside official docs and source code? Or those are enough?
Thanks! When the question formed in my head I kinda remembered a video I watched a few days ago: https://www.youtube.com/watch?v=krWLtVW4P_Y and the first ~20 seconds of it. But of course I don't actually mean it that seriously.
I also recall there is a list of obscure code (mostly drivers I recall, but could be wrong) that Linus himself recommended for new people to take a look, to promote to better standards, because no one. I forgot where he put the recommendation -- maybe it is just a comment at the top of the code block.
I wish I could find it again, but I probably need AI to help me with that. This is also very interesting to me as well, because I have always wanted to get into kernel development AND carve out a tiny teeny piece for myself.
Learn tooling, especially QEMU (vms are a must for kernel dev).
And find specific little projects that inspire you, "kernel dev" is a huge topic. Like a funny /proc entry, a netfilter hook, or a tiny filesystem. A concrete project will give you a clear path forward to research and experiment.

I think this kinda fits the bill, too -- labs on real Linux kernel, with grading support.
