# Puppy RTOS
Puppy RTOS 项目的目标是实现一个运行在低资源平台上的 POSIX 兼容实时操作系统，系统的原生接口就是 POSIX 接口，没有学习门槛。这是一个全新的项目，所以在实现的时候会多尝试一些新技术，最终目标是希望实现一个支持用户交互，可在线安装应用的实时微内核。
### Roadmap
**M0：一个最小实现的实时内核 [Doing]**
- 包含原子操作、实时调度、线程管理、线程间同步、中断管理、内存堆管理。
- 支持一个 Target，可以在 STM32L4 平台上运行。
- 支持两个工具链，gcc、armclang
- 充分的内核测试用例
**M1：一个最小实现的实时微内核 [ToDo]**
- 支持运行用户态应用
- 用户空间内存隔离
- 用户空间的应用崩溃不影响内核
**M2：一个支持用户交互的实时微内核 [ToDo]**
- 支持 apt install 安装应用
- 支持 apt update 检查更新
- 支持 apt remove 卸载应用
## 如何体验
### 下载工具链
```
wget -q https://github.com/RT-Thread/toolchains-ci/releases/download/v1.4/riscv64-unknown-elf-toolchain-10.2.0-2020.12.8-x86_64-linux-ubuntu14.tar.gz
sudo tar zxf riscv64-unknown-elf-toolchain-10.2.0-2020.12.8-x86_64-linux-ubuntu14.tar.gz -C /opt
/opt/riscv64-unknown-elf-toolchain-10.2.0-2020.12.8-x86_64-linux-ubuntu14/bin/riscv64-unknown-elf-gcc --version
```
### 配置编译
```
xmake f -p cross --sdk=/opt/riscv64-unknown-elf-toolchain-10.2.0-2020.12.8-x86_64-linux-ubuntu14 --build_board=qemu-virt-riscv -m debug
xmake
```
### 运行
```
qemu-system-riscv32.exe -nographic -machine virt -net none -chardev stdio,id=con,mux=on -serial chardev:con -mon chardev=con,mode=readline -bios none -smp 4 -kernel puppy.bin
```
**运行结果**
```
