Kernel From Scratch: From basic bootable kernel to advanced ELF memory parser & complete userspace implementation.

> Listing of project quest coverage

## KFS-1

- A kernel you can boot viaGRUB

- An ASM bootable base

- A basic kernel library, with basics functions and types

- Some basic code to print some stuff on the screen

- A basic "Hello world" kernel

## KFS-2

- GDT (Global Descriptor Table) Implementation

 -> Creation / Fill / Linkage

## KFS-3

- A complete memory code structure, with pagination handling

- Read and Write rights on memory

- User space memory and Kernel space memory

- Physical and Virtual memory

- Code helpers for physical memory, likekmalloc,kfree,ksize,kbrk

- Code helpers for virtual memory, likevmalloc,vfree,vsize,vbrk

- Kernel Panic handling
