My simple 64 bit kernel

Overview

This is a kernel or OS that is written in ASM and C. It's pretty simple and straightforward, though not very functional sometimes.

This serves as an educative demo of a kernel with simple commands and without multitasking or any kind of good IO interface. Don't take it seriously

Prerequisites

To install all prerequisites use these commands:

sudo apt update
sudo apt install qemu -y
sudo apt install qemu-system-x86 -y
sudo apt install xorriso -y
sudo apt install mtools -y

You will also need gcc and nasm for compiling files:

sudo apt install gcc
sudo apt install nasm

Installation

Linux Debian or Ubuntu

Just copy the repository in your directory using

git clone https://github.com/pi4erd/MyKernel.git

And that is all! You are ready for the next step.

Build and run

Linux Debian or Ubuntu

To build our little OS run:

make all # or just 'make', no difference

Then to run it just use make run or qemu-systems-x86_64 -cdrom build/os-x86_64.iso

And that is it!

You are ready to use it! Though, the only use now is education I suppose

Contributions

I will be glad if anyone points out any mistakes and corrects it to finally support floats. I am a beginner programmer especially in this topic. Because of that I want to learn more. Thank you!
