Osdev

Outline

I am going to develop a 64-bit kernel, which will abide by the following rules:

1. be written completely in the Rust programming language
2. support at least the x86_64 architecture
3. support the multiboot2 standard (GRUB)
4. work on BIOS (and UEFI)
5. have a functional
   1. exception/interrupt handling system
   2. memory management system
   3. task management system
6. abide by the microkernel architecture

Actions to take

My first course of action is to set up a development environment. I will use my nix-shell setup to manage my environment (read more) with one difference: I am going to use rustup to be able to manage my toolchains in a rust-toolchain.toml file.

So you want to write an operating system? Tough luck, you probably won’t. Just to shatter your dreams early I need to emphasize that an operating system (OS) is a very complicated web/pile of software. To be able to write it, you need to be well versed in a bunch of different standards and programming concepts. So you probably won’t write an entire OS by yourself.
