rCore-Tutorial-v3

rCore-Tutorial version 3.5. See the Documentation in Chinese.

Overview

This project aims to show how to write an Unix-like OS running on RISC-V platforms from scratch in Rust for beginners without any background knowledge about computer architectures, assembly languages or operating systems.

Features

• Platform supported: qemu-system-riscv64 simulator or dev boards based on Kendryte K210 SoC such as Maix Dock
• OS
  • concurrency of multiple processes
  • preemptive scheduling(Round-Robin algorithm)
  • dynamic memory management in kernel
  • virtual memory
  • a simple file system with a block cache
  • an interactive shell in the userspace
• only 4K+ LoC
• A detailed documentation in Chinese in spite of the lack of comments in the code(English version is not available at present)

Working in progress

• update Rust & RustSBI to latest version
• rewrite practice doc and remove some inproper questions
• add a new chapter about synchronization & mutual exclusion(up or smp?)
• format the code using official tools
• support Allwinner's RISC-V D1 chip
