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?

Just a quick reminder: NetBSD still has it and will very likely in the foreseeable future

It makes more sense to do this in a major upgrade like from kernel 6 to 7 but some cleanup is good.

What do you mean? The Linux kernel doesn't follow SemVer.

The 6.19 -> 7.0 version bump didn't have any more inherent meaning than 7.0 -> 7.1 or 7.1 -> 7.2.

Yay, reduced functionality 🥳

My man were talking about hardware from like the 90s lol. Linux is amazing on keeping old hardware going, but even it has to move on at some point.

I'm sure you'll be devastated to learn that Linux stopped supporting the i386 in 2012.

Virtually nobody is going to run kernel 7.2 on a 90s CPU without a time stamp chip. Its good practice to prune old and largely unused features once and a while

You know, Windows98 is still available

Yup. Linux isn't what it used to be anymore.

[-] NotSteve_@piefed.ca 1 points 54 minutes ago

What are you using the old x86 timing functionality for, or rather what would it be needed for?

[-] SMillerNL@piefed.social 2 points 1 hour ago

Time to ask for a refund of the 0 money you paid to use it.

[-] SocialistVibes01@lemmy.ml 1 points 1 hour ago* (last edited 1 hour ago)

That's not an individual problem, but you liberals only work in an individual and monetary logic. The Evil Empire's propaganda is efficient.

[-] Lettuceeatlettuce@lemmy.ml 9 points 4 hours ago

You're right, it's way better.

[-] non_burglar@lemmy.world 2 points 4 hours ago

You make it sound like no one can just go keep the older hardware alive by forking.

[-] SocialistVibes01@lemmy.ml 3 points 3 hours ago* (last edited 2 hours ago)

The fairy tale of fork freedom, just the fairy tale of market freedom.

Y'all are really pathetic.

[-] Grass@sh.itjust.works 2 points 4 hours ago

I'm not what I used to be

This happens every time I point put that losing these "old" kernel capabilities is in fact a loss.

Let them be stupid about it, all the code still exists to undo these bad decisions one day. It'll just be more work than it would otherwise be to fix what they broke.

I put them in the same category as AI sycophants, they can't see three feet beyond their own nose.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
