# eRhino
操作系统学习：RV64
## 设计
参阅 `./notes/{doc}.md`
## 进度
- [ ] IPC
- [x] 信号

- [ ] sysfs
- [ ] 具体文件系统
- [ ] FAT32
## (将)受支持的平台
- [x] qemu-virt: 4 cores 128MB ram with MMU
- [x] qemu-sifive_u: 5 cores(#0 disabled) 128MB ram with MMU
- [ ] k210: 2 cores 8MB ram with MMU *内存太少了哇*
- [ ] D1s(F133): single core 64MB with MMU
只有 virt 能跑，其他的会遇到莫名bug
## 标准库
~~Porting std is huge work, I wont do it at the current stage.~~
仅提供 `rinlib`
## 源码使用
构建系统用的 Justfile, 可执行名为 `/bin/just`
使用参数 `PLATFORM` 和 `MODEL` 来对应 `platforms/{{PLATFORM}}/{{MODEL}}/*` 的设备文件。
由于我不知道如何用 just 做到使用 dict 保存并应用 PLATFORM/MODEL 到 OpenSBI/PLATFORM/FW_CONFIG 的特定配置，编译或者运行需要 `just build(或run)_$MODEL`，要求指定型号。
### 构建
```sh
just PLATFORM=foo MODEL=bar build
```
### 运行
需要 `qemu-system-riscv64`
```sh
just run
```
### 调试
~~~用 gdb 调试会有字长问题，这里用`riscv64-elf-gdb`~~~
用 riscv64-elf-gdb 调试会有 rust-testsuit 问题，这里用 `git-multiarch`
```sh
just debug
```
