Zinnia

Zinnia is a modular 64-bit Unix-like kernel written in Rust.

The kernel implements most POSIX interfaces, and some BSD/Linux extensions like epoll and timerfd. It also implements DRM and evdev drivers for rendering and input.

[!NOTE] This repository contains only the kernel and drivers. If you want to get a bootable image, you might want to check out https://github.com/zinnia-os/bootstrap instead.

Building

Cloning the repository

git clone https://github.com/zinnia-os/zinnia
git submodule update --init --recursive

Compiling the kernel

To compile the kernel you will need:

• cargo
• rustc
• clang (Used for bindgen)
• lld

Make sure you have a full nightly toolchain installed, including the rust-src component.

The following commmand will build the kernel and all drivers for x86_64:

cargo +nightly build --release -Zjson-target-spec --target toolchain/x86_64-kernel.json
