Linux Kernel 6.12 Has Landed – And It's a Big One

cross-posted from: lemmy.zip/post/26533086

Linux kernel 6.12 is one of the most significant releases of the year, delivering a feature nearly 20 years in the making: true real-time computing.

Is there any work being to certify specific kernel versions for safety

It doesn't help that its not well named, realtime makes it sound fast.

One of the few things I remembered from my degree was the realtime programming course, because we got to program a model train set in Ada, on a 286(?), running on floppies. This was in ~2015, so ancient hardware even then, and it was slow, but it was "realtime".

Interestingly, my compsci degree never covered O notation, so that I've had to pick up along the way :/

As I expected, it got bounced over to Intel and the basic response was it's not ready yet.

Does this turn Linux into a RTOS that can do stuff like control the ECU or traction control for a motorcycle?

From what I'm hearing: yes

But you'd still be crazy to use it for either of those purposes, given how safety critical they are. I expect it would be more likely used in robots like Spot, or manufacturing robots.

Yea, given how new it is i probably wouldn't trust it for something that important. But in-theory it's meant to handle that type of embedded system

Really‽ That's a shame. It's one of the topics that, in my programming career, was regularly valuable and used. That, set theory, and discrete math have an been broadly applicable even in the most banal applications. It's a shame if it's not part of the CIS curriculum at some universities.

“FireWire improvements”

I haven’t heard anyone mention FireWire in 20 years.

This is BTW fixed in SOME versions of 6.13 but not all, and I haven't had a chance to test in 6.14 yet.
