ArceOS 框架设计
ArceOS的整体架构如下所示：
ArceOS 是一个开源的、组件化的Unikernel。以组合组件库的方式构建系统。使用Rust开发。
具有以下特点和功能:
- CPU架构: x86_64, riscv64, aarch64
- 运行平台: QEMU pc-q35 (x86_64), virt (riscv64/aarch64)
- 支持多线程: Multi-thread
- 调度算法: FIFO/RR/CFS scheduler
- 虚拟IO: VirtIO net/blk/gpu drivers
- 网络协议: TCP/UDP net stack using smoltcp
- 同步/互斥: Synchronization/Mutex
- SMP调度: SMP scheduling with single run queue
- 文件系统: File system
ArceOS 由apps、crates、modules组成
- apps: 应用程序。它的运行需要依赖于modules组件库。
- modules: ArceOS的组件库。
- crates: 通用的基础库。为modules实现提供支持。
当前ArceOS项目的apps列表如下:
