I've never worked on GPUs, will likely never work on drivers even, yet was able to follow along and find it interesting.

I'm going to upvote pretty much any reverse engineering monologue, especially one as accessible as this.

Are you saying this post is too nerdy for Hacker News? Stories come all the time, if you don't like it don't read it.

I didn't understand everything the author said, but I was able to get the gist of it. There GPU has a list of valid addresses and it's stored in a C style array with a terminator instead of a 1 indexed array with an object count in the Apple API style. The mismatch caused the author some confusion even after he discovered the existence of the buffer due to his code failing.

It's one of the many details that has to be understood in order to write an open source driver for the hardware. The open source driver will be necessary for people who want to install Linux on this Apple hardware.

> even after he discovered

She, fwiw.

Sorry. I completely forgot to check the byline.

small correction: the author is a woman

Yeah, well, you know, that's just like... your opinion, man.

...well, this is Hacker News, after all.

Then hide it and don't read it
