Linus Torvalds' Initial Comment On Rust Code Prospects Within The Linux Kernel

Kernel developers appear to be eager to debate the merits of potentially allowing Rust code within the Linux kernel. Linus Torvalds himself has made some initial remarks on the topic ahead of the Linux Plumbers 2020 conference where the matter will be discussed at length.

[...] Linus Torvalds chimed in though with his own opinion on the matter. Linus commented that he would like it to be effectively enabled by default to ensure there is widespread testing and not any isolated usage where developers then may do "crazy" things. He isn't calling for Rust to be a requirement for the kernel but rather if the Rust compiler is detected on the system, Kconfig would enable the Rust support and go ahead in building any hypothetical Rust kernel code in order to see it's properly built at least.

Linus Torvalds Wishes Intel's AVX-512 A Painful Death

According to a mailing list post spotted by Phoronix, Linux creator Linus Torvalds has shared his strong views on the AVX-512 instruction set. The discussion arose as a result of recent news that Intel's upcoming Alder Lake processors reportedly lack support for AVX-512.

Torvalds' advice to Intel is to focus on things that matter instead of wasting resources on new instruction sets, like AVX-512, that he feels aren't beneficial outside the HPC market.

    To begin, I'd +1 Funny you for the typos but I'm out of points.

    As to the assertion itself? Compilers can only catch you out making stupid mistakes that can be corrected easily all at once when you're done. They will not tell you if your shiny, happy algorithm (that had damned well better take more than one line) is doing something slightly different than what you meant it to. That's what unit tests, fuzzing, and martybs are for.

    To be clear, I wasn't insulting you. You expressed an extreme lack of confidence in your ability to write something correctly the first time. I took you at your word that you can't. I can though. Yes, I may have to recompile half a dozen times when I'm done to fix the few errors I inevitably code in but I will not have to recompile a couple thousand times like you would have.

    My rights don't end where your fear begins.

    Typos? It was past midnight and I was on my Android phone. I'd spent the evening doing battle with a micro SD card in an Android tablet. I accidentally formatted it as internal storage and it moved 7.5 GB of data. I had to figure out how to undo it. I learned all about MTD and failed to backup all the data to my laptop. Eventually I found the right pictures to point at on the Android device. Then I took the card out to reformat on my laptop. For the first time in my life I made a typo writing the exfat file system and hosed my laptops's EFI boot partition by mistake, so I had to fix that too.
