Linux 7.2 has landed, dragging x86 timing clean out of the nineties by making the Time Stamp Counter mandatory.

I wrote up a quick article on why ditching those ancient legacy fallbacks is good housekeeping, plus a few other bits like cache-aware scheduling and memory tweaks worth noting.

Is anyone still using legacy hardware? If so, what do you use it for?

I kinda miss the idea that the kernel would run on literally any hardware it ever did support, but I totally get it, especially now that there's an emphasis on reducing attack surfaces.

[-] khleedril@cyberplace.social 14 points 4 weeks ago

@davidgro @cm0002 At least you can still get the last kernel which ran on any hardware it ever did support.

[-] Zephyr@sh.itjust.works 8 points 4 weeks ago

Someone will keep up support and you're always welcome to merge it and compile your kernel.

I have some xeons in an old server running that I can't update to the next version of Rocky because the kernel won't support them :(

[-] boonhet@lemmy.zip 7 points 3 weeks ago

Isn't that just Rocky configuring the kernel that way? You're free to compile your own kernel and it'll still support even old pentiums, just not i486 in new versions

Lots of retro enthusiasts still use legacy hardware for all sorts of reasons... I fear that a fork of the kernel will be necessary in the near future to keep these machines running.

The notion of using Linux to revive old hardware and keep it out of the landfill may not last forever...

There are ultra long term support Linux kernels though.

Linux 6.12 will be supported until at least 2036 for instance.

Or just don't connect to the public internet and continue using a kernel that works? Even with internet, the attack vectors for such a machine are nearly non existent.

And why do they need to use the latest Linux kernel for that hardware, again?

[-] refalo@programming.dev 3 points 3 weeks ago* (last edited 3 weeks ago)

Security updates if you use it online or copy new binaries to run on it. Even if you're not worried about hackers, there can still be viruses and malware that destroy your data.

[-] menas@lemmy.wtf 3 points 3 weeks ago

I do agree. Maybe I'm little paranoid, but I feel like in some years, recycle old chips will be the only IT available

Just use NetBSD and never look back :)

Linux supports much less old hardware than its competitors.

I don't know why you're getting downvoted?

NetBSD

OpenBSD

I actually learned how to actually use a shell interface when I setup FreeBSD the first time. But other than tinkering with BSD's on occasion, I really don't have much experience with them.

To dismiss them outright is baffling to me.

I use a Compaq CQ510-SD for writing. Lovely small keyboard, only has a resolution of 1024x600, but with some zoom configured in autostart that increases to twice that. It works as little more than a glorified text processor, but it suits my needs just fine while I can't find its equal in the x64 or ARM market.

[-] somegeek@programming.dev 5 points 3 weeks ago

Use an ultra long support kernel like 6.12

[-] sudoMakeUser@sh.itjust.works 4 points 4 weeks ago

The keyboard does look lovely. Maybe a Chromebook with Linux? I don't know what the Linux world is like for those. I'm sure you've looked at them before.

[-] randamumaki@lemmy.blahaj.zone 3 points 4 weeks ago

I did, yes. Finding a 12" or 13" mini-laptop is just tricky. Might need to build one of those custom clamshells.

[-] boonhet@lemmy.zip 2 points 3 weeks ago

But why does it need updates if it works? Just don't connect it to the Internet and you can run it until either it dies or you die.

[-] randamumaki@lemmy.blahaj.zone 2 points 3 weeks ago

I tend to write on it on the couch or at the library or wherever, and then use syncthing to sync with my desktop. This does require keeping syncthing updated.
