Os Devlog: Intro

Introduction

I’ve been trying osdev for a few weeks now, and I decided that I would start writing a devlog :). My end goal is a simple unix-like system, that doesn’t have to be posix-compliant. If you want a look on the source, it’s available on my forgejo.

I will write devlogs here every once in a while. I won’t really be getting to the more low-level stuff, unless someone requests that. (see navbar)

Things done

As I previously stated, I have written this for a while now. I have been able to implement:

• A functioning GDT
• A functioning IDT
• A extremely simple keyboard driver
• A extremely simple display driver

Missing features

• I can’t get to Ring 3 for some reason (heelpp)
• No multitasking
• 2 System calls
