Kernel

This is a mere hobby kernel for 32-bit x86, to learn about OS/Kernel development.

I'm learning from osdev, adding features in no particular order, just implementing stuff I want to learn more about.

Dependencies

Meson
Ninja
QEMU

Nix

If you're using a the Nix package manager, a development environment is ready for you to use inside the flake.

$ nix develop .#kernel

Warning

This requires flakes support

Building

$ meson setup build --cross-file scripts/meson_cross.ini --reconfigure [-Dbuildtype=debug]
$ ninja -C build iso      # builds the kernel.iso file
$ ninja -C build qemu     # boots up qemu using the iso file

Testing

I don't know how I can test kernel code, so all tests are performed manually for the time being ...

$ ninja -C build qemu-server    # boots up a qemu server open for GDB connections
$ gdb -x .gdbinit build/kernel/kernel.sym

You can also run unit-tests on our libraries:

$ meson test -C build --print-errorlogs

Documentation

I try to keep the codebase well-documented. You can generate the full doc using doxygen:

$ doxygen docs/doxygen/Doxyfile # Requires you to also pull the git submodules
