01. Prerequisite Readings - josehu07/hux-kernel GitHub Wiki

Good online resources are your friends. There are also bad and misleading ones. Some tutorials are cleanly written yet adopted out-of-date techniques. Choose wisely!

Recommended Prerequisite Readings

OS conceptual materials (must have a solid understanding of OS theory):

• Operating Systems: Three Easy Pieces (OSTEP) by Prof. Arpaci-Dusseaus
• My reading notes on OSTEP book & lectures

Here are a few pages on the OSDev wiki worth reading before diving into OS kernel development:

• Required Knowledge
• Beginner Mistakes
• Getting Started
• Creating an Operating System phases overview
• Tutorials collection. Remember that not all tutorials suit your ideas perfectly, and lots of them have design flaws and even serious bugs, so choose wisely

The OSDev wiki is a great source (I would say the best so far) of kernel development resources. Most of the time, it is wise to follow the OSDev community members' advices.

• Writing an OS in Rust by Philipp (still updating...)
• The xv6 Kernel x86 ver. by MIT PDOS (no longer updated)

The basic structure of Hux kernel follows James' tutorial parts 1 - 6, but fixes bugs and problems as stated on the "Known Bugs" page and adds in plenty of my own design choices. Starting from the heap, Hux diverges away.
