StarryOS

A monolithic kernel based on ArceOS.

Quick Start

1. Install Build Dependencies

Install cargo-binutils to use rust-objcopy and rust-objdump tools:

cargo install cargo-binutils

Dependencies for C apps

Install libclang-dev:

sudo apt install libclang-dev

Download & install musl toolchains:

# download
wget https://musl.cc/aarch64-linux-musl-cross.tgz
wget https://musl.cc/riscv64-linux-musl-cross.tgz
wget https://musl.cc/x86_64-linux-musl-cross.tgz
# install
tar zxf aarch64-linux-musl-cross.tgz
tar zxf riscv64-linux-musl-cross.tgz
tar zxf x86_64-linux-musl-cross.tgz
# exec below command in bash OR add below info in ~/.bashrc
export PATH=`pwd`/x86_64-linux-musl-cross/bin:`pwd`/aarch64-linux-musl-cross/bin:`pwd`/riscv64-linux-musl-cross/bin:$PATH

Dependencies for running apps

# for Debian/Ubuntu
sudo apt-get install qemu-system

# for macos
brew install qemu

Notice: The version of qemu should be no less than 8.2.0.

Other systems, arch and version please refer to Qemu Download

2. Build & Run

# Clone the base repository
./scripts/get_deps.sh

# Build user applications
make user_apps ARCH=<arch> AX_TESTCASE=<testcases>

# Build kernel
make ARCH=<arch> LOG=<log> AX_TESTCASE=<testcases> build

# Run kernel
make ARCH=<arch> LOG=<log> AX_TESTCASE=<testcases> run

Where testcases are shown under the apps/ folder.

<arch> should be one of riscv64, aarch64, x86_64.

<log> should be one of off, error, warn, info, debug, trace.

More arguments and targets can be found in Makefile.

For example, to run the nimbos testcases on qemu-system-x86_64 with log level info:

make ARCH=x86_64 LOG=info AX_TESTCASE=nimbos run

Note: Arguments like NET, BLK, and GRAPHIC enable devices in QEMU, which take effect only at runtime, not at build time.
