# rCore

[![Build Status](https://travis-ci.org/rcore-os/rCore.svg?branch=master)](https://travis-ci.org/rcore-os/rCore)

Rust version of THU [uCore OS Plus](https://github.com/chyyuu/ucore_os_plus).

Going to be the next generation teaching operating system.

Supported architectures and boards:

* x86_64: PC (i5/i7)
* RISCV32/64: HiFive Unleashed, Kendryte K210, [FPGA running Rocket Chip](https://github.com/jiegec/fpga-zynq)
* AArch64: Raspberry Pi 3B+
* MIPS32: [TrivialMIPS](https://github.com/Harry-Chen/TrivialMIPS)

## Building

### Environment

* [Rust](https://www.rust-lang.org) toolchain
* Cargo tools: [cargo-xbuild](https://github.com/rust-osdev/cargo-xbuild), [cargo-binutils](https://github.com/rust-embedded/cargo-binutils)
* [QEMU](https://www.qemu.org) >= 3.1.0
* [musl-based GCC toolchains](https://musl.cc/) (only for building [user programs](https://github.com/rcore-os/rcore-user))

Setup on Linux or macOS:

```bash
$ rustup component add rust-src llvm-tools-preview
$ cargo install cargo-binutils cargo-xbuild
```

Or use Docker container:

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

### How to run

```bash
$ git clone https://github.com/rcore-os/rCore.git --recursive
$ cd rCore/user
$ make sfsimg prebuilt=1 arch={riscv32,riscv64,x86_64,aarch64,mipsel}
$ cd ../kernel
$ make run arch={riscv32,riscv64,x86_64,aarch64,mipsel}
```
