# matcha-threads

A simple and unsafe implementation of `cooperative-multitasking` in userspace
(see [`fibers`][fiber_wiki]).

This implementation should not be used for anything serious, it was just
created to type some lines of `asm` and filll a few evenings.

Supported platforms are `Linux` running on
- `x86_64`
- `arm64`

### Setup development environment
This project provides a [`Dockerfile`](docker/Dockerfile) with all the required
tools pre-installed.

To build and launch a container instance run
```bash
make docker
```
> On the fist invocation this takes some minutes as it needs to build the
> docker image.

Additionally the locally cloned repository will be mounted into the container
instance. This allows to use editors/tools installed on the host and to reduce
the image disk footprint.

### Build and run demo
The `x86_64` demo can be run as
```bash
make demo1
```
The `arm64` demo can be run as
```bash
make ARCH=arm64 demo1
```
> Before starting to compile & run for a different architecture the the current
> build artifacts should be removed via `make clean`.
