Developing an OS using Linux Kernel: A Low-Level Approach

TLDRLearn how to develop a custom OS using the Linux kernel with a focus on low-level development.

Key insights

💻Focus on using the Linux kernel to create your custom OS.

🔧Assumptions made include familiarity with Linux kernel and programming languages like C and x86-64 assembly.

📦Using a virtual machine is recommended for ease of recording and development.

🕒Creating necessary directory structures is crucial for the Linux kernel to boot up successfully.

🚧Setting up the boot process involves creating a grub configuration and defining system calls.

Q&A

What is the primary focus of the video series?

The video series focuses on using the Linux kernel to develop a custom OS at a low level.

Do I need prior knowledge of Linux kernel programming?

Yes, familiarity with the Linux kernel, C programming, and possibly x86-64 assembly is assumed for this content.

Why use a virtual machine for development?

A virtual machine simplifies the recording process and provides a controlled environment for OS development.

What directory structures are essential for Linux kernel development?

Common directories like bin, sbin, etc, lib, var, dev, proc, sys, run, and tmp are necessary for Linux kernel functionality.

How do you set up the boot process for the custom OS?

The boot process involves creating a grub configuration, defining system calls, and setting up the initial RAM disk for booting the OS.
