write an operating system (from scratch)

constraints

• intel x86_64 arch only

main goals

• 64bit
• smp (symmetric multiprocessing)
• multithreading & preemptive scheduling
• written in c and zig (and a bit of asm)
• (maybe) pci/e device enumeration
• (maybe) pci/e device driver

tools

Contribution

This project is meant for a YouTube series on how to write an os from scratch. PR on topics not yet covered will not be accepted (unless an issue was discussed and approved beforehand). Bug fixes and improvements for topics already covered are welcome as long as they don't deviate too much from the aim of this project (simplicity and clarity over perfection/performance)
