raspberry-pi-os

CheesecakeOS for Raspberry Pi Volume 0: Booting, Processes, and Virtual Memory is the first in what I hope is a series of github markdown tutorials or volumes on bare-metal from-scratch operating system development. I have dreamed of contributing to the Linux Kernel, but have yet to find the courage to jump in and do so. I started by attempting to read Understanding the Linux Kernel by Daniel Bovet and Marco Cesati, but found it was too advanced for me at the time. I found another text I credit with advancing my understanding, Computer Systems: A Programmer's Perspective by Randall Bryant and David O'Hallaron. I worked on the self-study labs from their book website, and found them to be a superb educational tool. Further, then becoming interested in what creating an operating system actually means, I stumbled upon Sergey Matyukevich's Ras

Yeah the github repo ( https://github.com/s-matyukevich/raspberry-pi-os ) shows it as being created just a little under 2 years ago

https://github.com/s-matyukevich/raspberry-pi-os Matyukevich page on GitHub has lessons with accompanying code to develop a Linux OS for raspberry Pi. The author goes into kernel, processor initialization, interrupt handling, scheduler, implementing syscall, and virtual memory. I like his approach for these reasons 1. Minimal workable code, 2. Points you to entry function in linux repo 3. Line commentary of those entry function Note that it's also a somewhat short read as he focuses on the practical implementations instead of the theory. I myself was hoping that the author continue developing the chapters on file system, drivers, and networking but seemed to have been on hiatus.
