All the concurrency bugs just vanish with Rust! Memory gets freed when it needs to be freed! Once you learn to make Rust work with you, I feel like it guides you into writing correct code, even beyond the language's safety promises. It's seriously magic! ✨

There is absolutely no way I wouldn't have run into race conditions, UAFs, memory leaks, and all kinds of badness if I'd been writing this in C.

After things work single-threaded in a driver as complex as this, having all the locking and threading just magically working as intended with no weird races or things stepping on top of each other is, as far as I'm concerned, completely unheard of for a driver this complex.

Basic compute works!!! And it even worked on the first try for the kernel side!!!!!! Rust is awesome!! 🚀🚀🚀
There's just one little problem... we're back to waiting for the GPU to power off after every command! This time I'm 99% sure it's a cache coherency issue... ^^;

I keep seeing sooooo many people confused by this one... a Rust panic is not a kernel panic, it's a kernel oops!
Basically it's like a NULL pointer dereference in a C driver... your driver crashes, that subsystem might lock up, but your whole machine doesn't go down.

I tried kmscube, and it was happily rendering frames. Then I tried to start a KDE session, and it crashed after a while, but you know what didn't cause it? 3 processes trying to use the GPU at the same time, allocating and submitting commands in parallel. In parallel!!

Looks like both GCC and clang actually compile it to a wide table, they don't know how to infer the division.
However, if you do the division yourself, clang does the bittield trick! GCC... does not ^^;;
The magic constant in x10 is 0x4141424344 which is 'AABCD' in ASCII.

Umm....
Hey Apple, I get that you wanted to use a piecewise approximation for the core current, but you know you have to actually line up the transition points, right?
I'm pretty sure the GPU doesn't start using less power when you cross 0.9V 😂
(Note: log Y axis)
7

327
And then all the memory management just... happens as if by magic. A process using the GPU exits, and all the memory and structs it was using get freed. Dozens of lines in my log of everything getting freed properly. I didn't write any of that glue, Rust did it all for me!
