rCore

NO LONGER MAINTAINED. You can see recent developments in:

Going to be the next generation teaching operating system.

Supported architectures and boards:

• x86_64(Tier 1): QEMU, PC (i5/i7)
• RISCV32/64(Tier 2): QEMU, HiFive Unleashed
• AArch64(Tier 2): QEMU, Raspberry Pi 3B+
• MIPS32(Tier 3): QEMU, TrivialMIPS

What's included

rCore has the following features:

• Linux compatible syscall interface: run Linux userspace programs
• Network stack
• Simple file system
• Signal system
• Async IO
• Kernel module

Building

Environment

• Rust toolchain
• QEMU >= 4.1.0
• musl-based GCC toolchains (only for building user programs)

$ rustup component add rust-src llvm-tools-preview

Or use Docker container:

$ docker run -it -v $PWD:$PWD -w $PWD wangrunji0408/rcore

How to run

$ git clone https://github.com/rcore-os/rCore.git --recursive
$ cd rCore/user
$ make sfsimg PREBUILT=1 ARCH=x86_64
$ cd ../kernel
$ make run ARCH=x86_64 LOG=info

See Makefile for more usages.
