You can't put more Type C/TB ports on the laptops, they already have as many as the SoCs can support... The MagSafe port is "bonus", it's not replacing a potential Type C port.

I think people really don't appreciate just how incomplete Linux kernel API docs are, and how Rust solves the problem. I wrote a pile of Rust abstractions for various subsystems. For practically every single one, I had to read the C source code to understand how to use its API.

Simply reading the function signature and associated doc comment (if any) or explicit docs (if you're lucky and they exist) almost never fully tells you how to safely use the API. Do you need to hold a lock? Does a ref counted arg transfer the ref or does it take its own ref?

✨ We got a bunch of Steam games to run on Asahi Linux!!! ✨ Most of them run at a solid 60FPS and all of them are playable on my M2 Pro~ 🚀 All running on a krun microVM with FEX and full TSO support 💪 Watch the stream: ▶️

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. In Rust? Just some logic bugs and some core memory management issues. Once those were fixed, the rest of the driver just worked!!

If it takes a whole year to get a concept as simple as a trivial "device" wrapper upstreamed (not any device model functionality, literally just an object wrapping a struct device so we can pass it around) then how is Rust for Linux ever going to take off?

✨Rendering on the M1 Ultra works!!!✨ It's pretty interesting! There are a bunch of new buffers that need to be allocated and it does kind of look like they might be doing something to balance work across both dies! 🚀 This is in the Python demo so far, so next time, Rust! 🦀

OMG every single reply/quote is reading this backwards... This actually fixes an abuse bug that has existed for years???? It's not bypassing your blocks, it's stopping that thing where people would block *you* and reply to you so everyone else sees it but not you...

Making the Rust bindings safe would have required duplicating much of the functionality of the C code just to track things to uphold the lifetime requirements. It made no sense. It would have been easier to just rewrite the whole thing in Rust (I might end up doing that).

glmark2 renders the Phong bunny at 16K×16K resolution (!!!) at almost 200 FPS on the M1 Ultra!!! 🚀🚀 For comparison, the M2 manages only 26 FPS ✨

I tried running glmark2 at 4K resolution on the Mac Studio, with the latest Mesa with the explicit sync patches... Final score: 4136 🚀 That makes it almost as fast as the highest score on OpenBenchmarking, a Radeon RX 6600 XT (4405)! And we're not done optimizing yet... ^^

When a callback is called are any locks held or do you need to acquire your own? What about free callbacks, are they special? What's the intended locking order? Are there special cases where some operations might take locks in some cases but not others?

The TLB issue is fixed!!!! 🎉🎉🎉 It turns out... there was no issue in the driver!! It was the hypervisor breaking it!!! 😱 I didn't think that was it because macOS worked, but I guess the macOS allocation patterns are so conservative they work without TLB invalidations... 🤦‍♀️

All the GPU initdata logic is ported over to Rust!! 🦀 We've got floats in the device tree compiler and in the kernel, and the numbers look good!!! 🚀 Let's wrap this up on Friday!! All that's left is to change a few flags and add the new memory buffers for the M1 Ultra!!! ✨✨

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.

... and this, by the way, is what a good compiler should optimize the switch version to! At least I've definitely seen compilers do it for Boolean output ((bitmask >> index) & 1). ✨

I know ancient iGPUs had that thing for setting the GPU memory size in the BIOS, but that's aaaaaancient and completely obsolete. If you still have that, just set it to the minimum value. The rest of memory will be unified. Apple dedicates a tiny bit of RAM secretly too!
