rCore Tutorial

rCore-Tutorial V3

Note: This project is no longer maintained. Interested students please see rCore-Tutorial-v3.

This teaching repository is a V3 version refactored after rCore_tutorial V2.

The goal of this document is mainly aimed at "students doing experiments". We will provide the completed code after the end of each chapter. Your exercises only need to be implemented incrementally based on the version we gave, and do not need to be written again according to the tutorial.

For students who want to implement a rCore in full, our documentation may not be very friendly. Because during the writing of the tutorial, we need to make a lot of trade-offs and considerations for clarity and comprehensiveness, and omit a lot of Rust syntax and OS-independent code to bring better readability and simplicity, students who want to refer to this document and implement it in full may not have the smoothness of copying from scratch to the end (this approach is not the original intention of learning), and may need to have some complete understanding and thinking.

Also, if you feel uncomfortable with the font size and style, you can adjust it through the buttons above the GitBook.
