This is essentially a code-to-code "translation" task. I can see how this looks very impressive, but IMHO it's like watching anyone else skilled at their profession.

Yeah - the title is a little off. My apologies! I'm not super knowledgeable about the kernel myself and while I did gain some knowledge from watching the video a lot of it looked like pure magic.

If a mod wants to edit the title to remove the "from scratch" and add that it's a device driver that would be great but otherwise, no worries
