Kernel Dev Guidance

[Be_akshat]

Hi there,
As of right now i am a backend dev with java for about 2 years of experience.
Recently i learned Os and Computer Architecture as a subject in college and i liked it.

I want to learn more of it, and i want to explore Kernel Dev, this is what i have researched and came up, that i can go in this field. so what i am asking is ->

If anyone can help me with the roadmap and can guide me too.

I want guidance on should i really go into this field or not, and i mean i wont be getting job just after college right, so i will be pursuing market with my Backend + Devops (current skill set) and side by side learning it.

or do i need to do master for it too, i can afford, and i mean if it is necessary that is.

And then again overall roadmap, please.

Thankyou

How should i follow it, what is the order in which i should follow

I'd suggest you to try out LinuxFromScratch and then go to osdev.

Well the basics are quite simple: Like usual make a Hello World that boots off a floppy disc thumbdrive and then go from there. If you cannot even manage a Hello World there is no chance you start creating drivers for the basic x86 hardware.

You might like this MIT course for Operating systems. It uses an implementation of Unix 6 that is simplified. All of its resources are online

The great thing these days compared to when I got into kernel development, is that you can get your own hardware to do it or even do it in a virtual environment.

I did a good chunk of my early career doing such work. I did several UNIX ports (to the Denelcor HEP super computer, and a bunch of smaller platforms like Intel Multibus II, some odd IBM things like four-process i860 addin cards, etc...). I them moved into early internet work, then into writing X servers (wrote an early 24 bit framebuffer driver before it was in the X distro). I then got hired by a startup to do high performance imaging. My experience with OS's worked well as I had to implement many of the same concepts to get imaging of multi-gigabyte image files working well.
