Andreas Kling 7ef9c703d2 Kernel: Unbreak SlabAllocator after startup-time constructors
Now that the kernel supports startup-time constructors, we were first
doing slab_alloc_init(), and then the constructors ran later on,
zeroing out the freelist pointers.

This meant that all slab allocators thought they were completelty
exhausted and forwarded all requests to kmalloc() instead.

Serenity

Graphical Unix-like operating system for x86 computers.

Travis CI status

About

I always wondered what it would be like to write my own operating system, but I never took it seriously. Until now.

Serenity is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by me, for me, based on the things I like.

If you like some of the same things, you are welcome to join the project. It would be great to one day change the above to say "this is a system by us, for us, based on the things we like." :^)

I regularly post raw hacking sessions and demos on my YouTube channel.

Sometimes I write about the system on my github.io blog.

There's also a Patreon if you would like to show some support that way.

How do I build and run this?

Make sure you have all the dependencies installed:

sudo apt install build-essential curl libmpfr-dev libmpc-dev libgmp-dev e2fsprogs qemu-system-i386 qemu-utils

Ensure your gcc version is >= 8 with gcc --version. Otherwise, install it (on Ubuntu) with:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get install gcc-8 g++-8
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-8 800 --slave /usr/bin/g++ g++ /usr/bin/g++-8

Go into the Toolchain/ directory and run the BuildIt.sh script. Then source the UseIt.sh script to put the i686-pc-serenity toolchain in your $PATH.

Once you've done both of those, go into the Kernel/ directory, then run ./makeall.sh, and if nothing breaks too much, take it for a spin by using ./run.

You can vastly reduce the build time of successive rebuilds of Serenity by installing ccache and exporting PRE_CXX=ccache

Bare curious users may even consider sourcing suitable hardware to install Serenity on a physical PC.

Later on, when you git pull to get the latest changes, there's no need to rebuild the toolchain. You can simply rerun ./makeall.sh in the Kernel/ directory and you'll be good to ./run again.
