> Dave Airlie just announced in the Maintainers Summit that the DRM subsystem is only ""about a year away"" from disallowing new drivers written in C and requiring the use of Rust.

wow

When the C absolutist maintainers fought for control over the ability to keep Rust out of their ballpark, I didn't expect the reverse to happen.

Still, I think it makes a lot of sense. Completely new GPU drivers are quite rare and the macOS drivers from Asahi are a showcase proving that Rust and GPU drivers work together well. If there's any subcomponent switching to Rust-first for new contributions, it makes sense for it to be the one that had already been proven to be Rust-compatible.

I would envision to see some more GPU drivers from Chinese companies like MooreThreads

Asahi project looks barely alive, almost abandoned. I know that their explanation of low activity is that they are being active elsewhere, supposedly pushing all their work upstream, but this has been happening for months and they don't give any reports about their progress, so I'm worried it will all die soon. And given that the project barely brought some Linux compatibility for m1 and m2 hardware and no prospects for bringing similar compatibility for newer generations - I fear it all will be kinda useless in the end.

Weren't the old Linux kernel developers promised the opposite by Linus Torvalds? That they would be able to continue writing in C?

Means that other platforms need to allow Rust in the kernel too in order to use future drivers.

What do you mean other platforms?

Also they can just expose c bindings to these rust libraries no?

that is so ridiculous.

Somebody needs to tell whoever wrote the drivers in the PC where I'm writing this.

Can't wait to write a Rust driver for my eink tablet <3

Interesting to see the building blocks come together. I hope that they can lay foundations that last.

Tyr is a Danish metal band. Period. :-)

I thought Tyr was the Norse god of War & Justice.

Considering that the Mali GPUs were developed by ARM Norway, and this driver is Just, I would say this is one aptly named driver.

T-Y-R is also the root in semitic languages (eg, Hebrew and Arabic) related to flying! Maybe not on purpose, but I really like that incidental connection, given the combined reputation of rust and GPU operations for being fast.

As a Hebrew speaker I cannot understand how you came into this conclusion. The closest I can think of is ת-י-ר, which is the root of being in a trip.

Technically they are from the Faroe Islands. Great band, seen them live many times.
