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
