LKModel

A modular OS-Kernel model written in Rust. It's a base on which We study how to use components to construct various kernels.

Many original components come from ArceOS.

Current target is to construct a monolithic kernel which is compatible with Linux-ABI, i.e. any linux binary user-app can work on lkmodel directly.

Quick Start

1. Preparations

Install cargo-binutils to use necessary tools:

cargo install cargo-binutils

Install qemu:

# for Debian/Ubuntu
sudo apt install qemu-system

Install gcc-riscv64-linux-gnu:

sudo apt install gcc-riscv64-linux-gnu

Install ltp - Linux Test Project (a forked version with minor fixes).

Put it into the same parent directory with lkmodel itself.

git clone git@github.com:shilei-massclouds/ltp.git
cd ltp
make autotools
./mk_riscv64.sh

Directory layout is just as below:

ParentDir
|
+---lkmodel
|
+---ltp
|

2. Build & Run

make prepare
make run

A monolithic kernel with initial user-app hello starts as below:

[userland]: Hello, Init! Sqrt(1048577) = 35190

The full form of building command:

make run LOG=<log> INIT=path/to/user_app

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

3. Test

Run btp tests (internal tests):

make prepare
make run INIT=/btp/sbin/runbtp

Run ltp tests (work in process):

make prepare
make run INIT=/btp/sbin/runltp

Run all base components tower-tests:

./test_all.sh
