Developing a Multithreaded Kernel From Scratch: Part Two - Module Two

This course is the continuation of Part 2 Module 1, where we continued building the 32-bit PeachOS kernel, into a fully functioning 64-bit multitasking operating system. In Part 2 Module 2, we take the project to the next level by continuing the development from Module 1. By the end of this course you will have a fully functioning 64-bit operating system capable of GUI windows, task scheduling and more. Keep reading for the full details.

Part 2 - Module 2 (This Module)

Module 2 builds directly on the work from Module 1 and focuses on turning the kernel into a full graphical operating system with multitasking, drivers, and a rich user experience.

You will:

— Expose standard C library functions (fopen, fread, etc.) to userspace through isr80h.
— Build the complete windowing system, with support for fully interactive GUI elements.
— Implement an NVMe SSD driver, enabling high-speed reads from modern solid-state storage.
— Add full PCI/PCIe support, including bridges, making the kernel capable of scanning and interacting with a wide variety of devices.

— Building a disk streamer cache to speed up program loading by 10x to 20x.
— Access a GitHub repository of user programs that you can run directly on your OS. You’ll even be able to submit pull requests to share your own user-space programs with other students in the course.

By the end of this module, you’ll have created a multi-threaded, 64-bit, GUI operating system from scratch bootable on modern hardware and extensible enough to run real user applications.
