This project was done out of an interest in operating systems. As a base I used a previously offered course on operating systems at Georgia Tech, which is no longer offered. I completed all parts of the course excluding networking. I decided not to do networking because I would like to implement network drivers in safe rust instead of writing safe wrappers for unsafe c.
The current focus of the project over the past week has been moving away from the course and towards modern Rust features. After this, I will proceed with working on
Currently, the project is on 1.68.0-nightly. I'm working on making it easier
to run on general (more) hardware, but for now qemu is recommended with the
settings in the Makefile.
- Allow processes to open files
- Add more system calls read, write (beyond single characters), fork, exec, wait, and pipe (maybe more?)
- Implement shell and have stdin, stdout, and stderr
- Make the file system writable*
- Move from the current c library to a rust library
- Add page swapping mechanisms
- Allow the stack to grow downwards (ie outside one page of memory)
- Use smaller pages
- Introduce a feature-rich IPC structure.
- Support ELF file format
- Add user space concurrency features (including locks, CVs, and semaphores)
- Work on a hosted hypervisor
- Networking
- Use cargo fuzz and miri to libraries for security.
- Update bootloader
- Create a mkfs tool to make filesystem without needing to worry about OS/architecture (like xv6-riscv)
- Use cargo clippy
* Asterisks suggest features are in a partially complete state, but require more work or coverage testing.
