This is Alyssa Rosenzweig. She reverse-engineered Apple's M1 GPU with no public documentation and also developed an open-source Linux driver. (lemmy.nz)

I admire people like this because even though there's like 3 pieces of hardware I wish I could fix like this, I've got no clue where to start. And except for one, most are simpler devices than the M1 GPU.

Some of the basics of reverse engineering:

  • Learn to use a binary editor to inspect compiled binaries
  • Learn to debug without symbols
  • Learn to use a decompiler
  • Learn to inspect the traffic between the device and the OS

It's kind of monumental and there's no real finish line for learning any of them.

Depending on what you want to do you need a lot of time, dedication, tools and probably money.

Well, one is a GPU like this one that only has 2D support and it's apparently perpetually stuck as experimental. The second one is a trackpad / numpad combo that someone else got working but because the code never got upstreamed it broke. The last one is an internal microphone that might have support in the kernel but it might be missing quirk flags or a small change in how it works.

That sounds like reading a lot of documentation and testing stuff out when no dox is available.

And probably you first need to learn about each device how they function on an os level...
