- Featuring a unique file system: zipfs. Your whole file system is mapped in memory from a single zip archive 😙👌
- Re-live your glory days with keyboard and mouse drivers from the PS2 era.
- Run RIP relative executables in userland with support for a whopping 1 system call(s)!
- The kernel is written in nasm, C, Rust and Zig for maximum spaghetti!
- Feel protected by SMEP and SMAP. Now you only have to worry about performance!
- NoTakeBack heap-allocator, don't worry about
free()'s, you can't anyway! - And of course: you can render a mandelbrot!
A little appetizer of what you'll experience before we begin.
# Build in docker.
$ docker build -t lappis-builder .
# We set --user to create build artifacts as our user.
$ docker run --rm -it --user "$(id -u):$(id -g)" -v $PWD:/lappis lappis-builder
# Run on host.
$ ./run.sh
We need a few dependencies before we can compile and run lappis.
Arch
# Arch
# Build
pacman -S nasm mtools clang rustup zig libisoburn
# Dev
pacman -S bear
# Run
pacman -S qemu-full
Ubuntu
apt install -y nasm clang mtools
# Can't believe this is the recommended way to install rustup...
curl https://sh.rustup.rs -sSf | sh
snap install zig --classic --beta
We need to tell Rust to use the nightly channel and configure it so that we can build freestanding targets.
rustup toolchain install nightly
rustup override set nightly
rustup component add rust-src --toolchain nightly-x86_64-unknown-linux-gnu
Now we are good to go!
Just run!
make run
In the near future:
- Scheduling
- shell / pid 0 aka init
The name original name was lapis, which means stone in latin since an operating system acts as the foundation for what's to come. However, it fits even better than we imagined since this OS is as dumb as a bag of rocks.
Later, the name affectionately became Lappis.
