Kernel is an experimental and educational project.

First, you will need the following software before building the kernel:

• nasm
• clang

Addionnally, if you intend to develop or debug the kernel, you would install:

• bochs
• qemu

gcc should be able to replace clang but we wont test the kernel with it.

We make use of the excellent Pure64 bootloader but it required few modifications to run our kernel.

git clone --recursive git:https://github.com/nizox/k.git
cd k/
make

With bochs:

cd build/
bochs

With qemu:

cd build/
qemu-system-x86_64 -drive file=system

Every piece of code is documented in place.

• Pure64 initializes long mode (64bits mode) for us, including the GDT. We must do it ourself if we want to be multiboot compliant.

• Prepare exception and IRQ handling
• Write text to the screen (console code)
• Paging and memory allocation
