# 🚀 Dandelion : Microkernel Real-Time Operating System in Rust
**Dandelion**. Meet your constraints.
> Ainsi, toujours poussés vers de nouveaux rivages,
>
> Dans la nuit éternelle emportés sans retour,
>
> Ne pourrons-nous jamais sur l’océan des âges
>
> Jeter l’ancre un seul jour ?

## Motivation
This project aims to create a microkernel real-time operating system using the Rust language. It addresses a large area of design techniques and algorithms so as to reach three defined goals :
- **deterministic** execution time of the programs (or subparts of them), allowing the processes to be managed accurately
- **correctness** of the time when a result is expected, to meet or miss the deadlines, where treatment marks the difference between soft and hard RTOS
- **predictability** of the deadline associated with a set of constraints to define an expected state of the system
## Main design characteristics
Dandelion is a hard time-sharing RTOS with a three-level scheduler
- admitter (long-term) : estimate job completion time and accept it or not
- swapper (medium-term) : swaps in and out the processes, depending on their activity
- dispatcher (short-term) : decide which ready process to run and to which processor/core to assign
## Technical choices
## Getting started
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See [deployment](#Deployment) for notes on how to deploy the project on a live system.
### Prerequisites
First of all, you need to install the Rust toolchain, available on the [official website](https://www.rust-lang.org).
Then you need to install an emulator to run the RTOS. We recommand [Qemu](https://www.qemu.org/), but any other emulator able to read iso images is suitable for the job.
### Installing
First you need to clone the repository:
```
git clone https://github.com/AntoineSebert/dandelion
cd dandelion
```
Then you need to build the project and generate an iso image of the RTOS:
```
cargo update
cargo build
```
### Running the operating system
Once all previous steps have been completed successfully, simply run the project:
```
cargo run
```
## Running the tests
```
cargo test
```
