# DevOS
[](https://devos.zulipchat.com)
[](https://github.com/tsatke/devos/actions/workflows/build.yml)
An operating system and kernel developed with the Rust programming language.
[Requirements](#requirements) •
[Features](#features) •
[Build and Run](#build-and-run)
### Requirements
* QEMU (for running and testing the kernel)
* [`rustup`](https://rustup.rs)
* `cc` (probably already available on your system)
* `mke2fs` for now
With those installed, you can simply run `cargo build` to build an image.
If you also have QEMU installed, `cargo run` and `cargo test` also will work.
### Features
- [x] Heap
- [x] Syscalls
- [ ] Drivers
- [x] PCI driver
- [x] IDE driver (no ATA)
- [x] VGA
- [x] xHCI
- [ ] USB
- [ ] NVMe
- [ ] Networking
- [x] Virtual File System with EXT2 implementation
- [x] Preemptive multitasking (processes & threads)
- [ ] Interactive shell
- [x] Test framework
### Build and Run
To run the kernel in QEMU
```plain
cargo run
```
### Running tests
To run tests with QEMU, run
```plain
cargo test
```
This will run kernel unit tests, as well as all `test_kernels`.
### Debugging
To debug the kernel in QEMU, run
```plain
cargo run -- --debug
```
and then connect to the QEMU instance with `lldb`:
```plain
lldb -s debug.lldb
```
