I've hacked around in SerenityOS from time to time, mostly to familiarize myself with the basics of an operating system. I've found the code incredibly readable. Even a simple web developer like myself can understand most things. It is not cluttered by macros and has limited CPU architecture support, which to me is a huge plus since it makes the codebase less intimidating. Inspired by it, I wondered how hard it would be to build my own kernel. Well, it is hard of course, to make something actually useful, but what if i strictly focus on the basics? Turns out, not too hard. With Claude that is. I had a few ideas on what I would like to accomplish. Besides the kernel basics like your allocators, MMUs, interrupt handling, schedulers, I was really interested in learning one thing specifically. That is io_uring. I wanted to build a kernel that would largely avoid sync system calls and instead borrow the ideas from io_uring for all user-space I/O operations. I also did not want to im...
