Linux 6.13 Released

"Nothing horrible or unexpected happened last week," Linux Torvalds posted tonight on the Linux kernel mailing list, "so I've tagged and pushed out the final 6.13 release."

Phoronix says the release has "plenty of fine features": Linux 6.13 comes with the introduction of the AMD 3D V-Cache Optimizer driver for benefiting multi-CCD Ryzen X3D processors. The new AMD EPYC 9005 "Turin" server processors will now default to AMD P-State rather than ACPI CPUFreq for better power efficiency....

Linux 6.13 also brings more Rust programming language infrastructure and more.
Phoronix notes that Linux 6.13 also brings "the start of Intel Xe3 graphics bring-up, support for many older (pre-M1) Apple devices like numerous iPads and iPhones, NVMe 2.1 specification support, and AutoFDO and Propeller optimization support when compiling the Linux kernel with the LLVM Clang compiler."

And some lucky Linux kernel developers will also be getting a guitar pedal soldered by Linus Torvalds himself, thanks to a generous offer he announced a week ago: For _me_ a traditional holiday activity tends to be a LEGO build or two, since that's often part of the presents... But in addition to the LEGO builds, this year I also ended up doing a number of guitar pedal kit builds ("LEGO for grown-ups with a soldering iron"). Not because I play guitar, but because I enjoy the tinkering, and the guitar pedals actually do something and are the right kind of "not very complex, but not some 5-minute 555 LED blinking thing"...

[S]ince I don't actually have any _use_ for the resulting pedals (I've already foisted off a few only unsuspecting victims^Hfriends), I decided that I'm going to see if some hapless kernel developer would want one.... as an admittedly pretty weak excuse to keep buying and building kits...
"It may be worth noting that while I've had good success so far, I'm a software person with a soldering iron. You have been warned... [Y]ou should set your expectations along the lines of 'quality kit built by a SW person who doesn't know one end of a guitar from the other.'"

Dunno about that

I lost HDMI sound on my linux. Put it back using the old driver, but it is an unpleasant downgrade with little or no information on how to recover from it. I get "no PCM in topology for HDMI converter" and no sound interface.

Some day I'll dig deep enough to figure out what is causing this shit if it doesn't resolve itself out.

Are you using Nvidia by any chance? I find that the Nvidia experience is getting worse and worse. Right now I'm having issues with monitor detection, it seems to take approximately forever to the system to react to a newly connected display.

Lazy preemption

[test321]

The highlight on lwn and kernelnewbies is Lazy Preemption. https://kernelnewbies.org/Linu... [kernelnewbies.org] https://lwn.net/Articles/99432... [lwn.net]
Personally I look forward new schedulers based on this preemption mechanism. I am already extremely impressed by the state of the linux scheduler in my daily routine. Even at very high loads (compiling a big project) and playing a small game or doing some office tasks while I wait, linux is incredibly reactive. "top" might report a ridiculous load like 60x that should make the whole machine lag, but it is barely noticeable, just a small overhead when opening new applications. New schedulers might be even better.

This kind of thing is one of the reasons I really like Linux. You can do stupid shit and the underlying OS is really robust and generally doesn't choke. This makes one off (i.e. code where it's not worth doing it "properly") way easier.

Until you run out of RAM, then randomly shit starts dying.

Re:

[serviscope_minor]

No operating systems deal very well with things running out of RAM. I've find that running with plenty of swap space prevents the worst kinds of thrashing when one process decides it wants all the RAM and then some.

Re:

[Tough Love]

Don't whitewash it. Linux's low memory handling always has been and still is shit. Claiming that other OS low memory handling is also shit is mere whataboutism. There is no excuse for Linux's broken fucking memory manager being so broken - for literally decades.

Re:

[Tough Love]

PS and LInux's shitty low memory handling is going to stay shitty as long as users keep whitewashing it. If that's you then suck it up. Or better, just shut up.

Re:

[serviscope_minor]

Good grief who pissed in your cornflakes?

What specifically are you talking about?

The main problem when memory gets low, and especially when there's almost no swap (like the ubuntu default settings) is that the only thing available to the kernel is to discard read-only mapped executable pages. As a result the system thrashes massively, because loading one page necessitates others be discarded, so the next scheduled process has to wait for its pages to be loaded and so on.

Now, you could make the kernel not di

You know just enough about the problem to be hazard, coupled with your supreme confidence that you know it all. Linux VM consistently makes wrong decisions about what to kill and spending practically endless time gazing at its navel thinking about it. You've seen this countless times, don't lie. And after all these years Linux is still absolute crap at detecting and dealing with use-once patterns such as updatedb. For starters.

You should actually shut up with your naive brain dumps and listen more if you wa

Oh you're one of those guys! The ones that spew ever angrier and more insulting screeds but mysteriously fail to say anything of substance or even cite anything of substance. It also seems you took offense at... me saying Linux is at worst not worse than the competition.

Enlighten us then. What is the right decision on what to kill?

Re:

[Tough Love]

So pretty much confirmed. You haven't got the foggiest clue. Not that it wasn't immediately obvious from your first post. Where kernel is concerned you are best advised to sit down and shut up.

Re:

[Tough Love]

Come to think about it, there's a remote possibility you might actually want to learn enough to be a productive contributor. Emphasis on the remote. If that is the case then less blathering and more listening thank you. There is enough technical content in my post above that any competent kernel engineer would know precisely what I'm talking about. But you... just don't make fucking assumptions based on your nonexistent current comprehension.

Re:

[serviscope_minor]

Insults are not the same as knowledge, no matter how angrily you make them, and no matter how much condescension you slather on top. You have demonstrated the latter, but not the former. All you've done is declare linux is crap, but you appear to be unwilling to actually back up that claim, either with a discussion or with links.

All my request for info have been met with a blizzard of invective. I think you don't have the knowledge, prove me wrong

Re:

[Tough Love]

Yeah, confirmed, you're just a self absorbed dunce who fancies himself some kind of computer expert. Raised to have high self esteem in the absence of achievement. Standard issue blowhard. Have a nice day.

Re:

[serviscope_minor]

It's trivial to prove me wrong. And yet you can't.

Heck, I claimed no expertise, and even asked you for details. If you can't even muster up the knowledge to explain your point to me it's cost you have even less knowledge than I do.

Re:

[Tough Love]

even asked you for details

Try it with a civil tongue in your head. See if you can manage that for one entire post. I have my doubts.

Re:

[Tough Love]

Linux is no worse than any other operating system when it comes to OOM conditions

So? That is no excuse for Linux sucking hard the way it does. Asshole.

Never underestimate the amateur

[rickb928]

When I was young, and undirected, I tried building projects out of Popular Electronics. Among these, a pseudorandom generator, which I still have on the original 70s breadboard, and began my long infatuation with XOR gates. Then a NiCad battery rejuvenator of dubious utility, to help manage the pack of 20 cells I used to power a belt mount cassette player to wear while I skated around the city, oh the days*. And out of the blue, a weird analog synthesizer-like gadget to take inputs and modify them beyond recognition. This I made several of, one for a vibraphone player who made good/great use of it, and one for a rock guitar player who asked for mods for a frikin year, drove me crazy. It became a wacko pedal, and he seemed to use it a lot until it finally got dropped off the van and lost. I still resent that.

Linus, go forth and pursue this, you will at least help others have some more fun. A worthy second calling, do not doubt it.

What is this?

[godrik]

Wait, not a story about politics, or climate change? Nor is it a story about AI or block chain? Where are we? This isn't the slashdot I know! It's like a news for nerd!

Pedal kits

[ZipNada]

I had a look at some of those kits, they are interesting and seem pretty easy to put together. They are circuit reproductions of classic pedals which you can hear on youtube videos to get an idea of what you might like to have. Unfortunately the one I want is sold out due to Xmas purchases so I'll have to wait a while.
