As a WIP, currently it is just a minimal kernel for x86_64 that boots with the [Limine boot protocol](https://github.com/limine-bootloader/limine/blob/trunk/PROTOCOL.md).\n\n## Build\n\n### Building a GCC cross-compiler\n\nA GCC cross-compiler targetting x86_64-elf needs to be built. Follow [these instructions](docs/building-an-x86-64-gcc-cross-compiler.md) to build one.\n\n### Building the OS\n\nRun `make` to build the kernel `davos.elf`.\n\nRun `make iso` to build the kernel and a bootable CD-ROM `davos.iso`.\n\n## Booting the OS\n\nThe OS can be booted using any VM or physical machine capable of booting from CD-ROMs. For development, consider the [qemu](https://www.qemu.org/download/) VM.\n\nIf using qemu, the OS can be booted from the ISO using `qemu-system-x86_64 -cdrom davos.iso`.\n\nAlternatively, run them `make qemu` to build the kernel and CD-ROM and run qemu all in one step.\n\nUse `make debug` to start QEMU in the background with an attached GDB instance.\n\nUse `make test` to start QEMU with debug messages and tests enabled.\n\n### QEMU on WSL2\n\nAdditional steps need to be taken to run qemu on WSL2 since it requires a GUI.
