Linux 6.12 Released, Gets Real Time Powers

[@OceanusHelios]

My first exposure to a real time operating system: I watched a video about Ferrari. The suspension system on the car was operated by a real time operating system. It could adjust the suspension rigidity on the fly down to microsecond responses to make the car effectively glued to the road. I am a machinist. CNC machines require real time responses. If they don't have it, it means destroyed workpieces, broken tools, and possibly a broken very expensive machine. People use their computers for information, mostly. But computers are also meant for control. Once you go real-time: Then...you finally have the ability to control things on the fly in real time. Yes, there will always be some latency caused by the laws of physics. But, this makes so many more things possible, especially in the area of robotics and automation. This is absolutely brilliant, and is bigger than I think most people realize. Twenty years from now, people will understand just how important it is. It is putting a real time operating system in the hands of the user, and not locked behind some proprietary over expensive system obscured by being binary only.

Thank you for the comment! I am very much looking forward to where this will lead.

This is great news for Linux in general. I hope this can lead to more companies considering the platform for their use cases. 👍

[@LinuxRenaissance]

I re-watched my video and I regret not saying this: I actually think this news is very good for hobbyists and tinkerers. Those people tend to be very innovative and this is good for the whole community. Companies, meanwhile, nothing drastic changes for them because Linux was real-time capable since a long time ago. You just had to patch it with the code that was not officially a part of the kernel. But now that it is more eyes will be on the code. Overall I think this is a really cool milestone.

@@LinuxRenaissance I'm on cachy os at the moment 😂 i haven't use arch based systems for a long time. After watching your video, sure enough it was ready for update.

[@DV-ml4fm]

This is great news. It just goes to show when you have thousands of talented collaboratters good things happen.

[@LinuxRenaissance]

My thoughts exactly. I love this and I just published some more good news to keep the momentum :)

[@DV-ml4fm]

@LinuxRenaissance That's real cool! 👍🙂👍

[@IceBlade1992]

sounds good to me and it might effetc other audio problems wen things get delayed with wierd audio cuts.

[@LinuxRenaissance]

Thing is, you need to use a different kernel to get RT functionality. Both on Fedora and Arch you need to install and boot linux-rt kernel if you need it.

[@NoiseCommander3DS]

Good news are welcome on these dark days

[@LinuxRenaissance]

We need more good news. I’ll try to bring more.

[@mkrleza]

I am not sure that I would like it if Linux started ruling the world (in desktop use). I think 5%-10% would be a sweet spot, IMHO.

[@LinuxRenaissance]

Yes, I agree with that percentage in desktop. It would be a rather nice sweet spot.

YT autodeletes my longer explanation comment, so next try TL;DR, YT hates spreading real information: Arch Linux, Kernel 6.12 and Zen Kernel 6.12 from Core Testing and Extra Testing Repositories have RT still disabled. They did not update the kernel build configuration, they still use dynamic preemption full, preempt_rt is not enableable for any Arch user who did not compile her own kernel. The only change that has been made in the source code was, that in the kernel build configuration RT could be enabled with another oneliner, but it has to be enabled there during build or it is disabled, basically nothing changed, currently. 6.12 for Arch Linux users like me BTW, no realtime, sadly. I was waiting for that, this would have been better than my birthday or Christmas or whatever festival, but this is a huge disappointment, currently. Please, anyone, enable RT during build, especially for Zen kernel which I use. Thanks. 🙏 🐧❤🖖🎗️

[@LinuxRenaissance]

Wait, really? Arch RT kernel is not what I thought it would be? I was planning to do a game benchmark between all Arch kernels, but if your info is accurate then I will need a different distro for my future video.

[@rodrigoetoobe2536]

windows still holds 96.61% of desktop PC gamers, and curiously, there is more arch users than ubuntu users. If this shit reduces drawcalls latency, you could get a performance boost. Also modern AAA games uses cpp with RAII, that means that they do a shit ton of malloc() and free(), RAII is extremely bad for games, but for those games that use that shitty technology, this realtime thing would increase performance? idk.

[@LinuxRenaissance]

In theory RT could increase 1% lows in video games, but decrease average framerate. Depending on how the game is programmed. I am planning to benchmark some games once 6.12 hits Arch Linux.
