Linux 7.2 finally cuts off ancient x86 fallback code (unknownuniverse.uk)

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?

Virtually every SaaS platform runs on Linux.

Mine don't.

70% of cellphones run on Linux.

Source?

Even compared to FreeBSD, NetBSD is more of a niche OS for hobbyists.

Compared to Windows, Linux is more of a niche OS for hobbyists. (My everyday device is a desktop, not a router.) Your point is what exactly? Operating systems need a certain market share to be good? Lol. Seriously, just lol.

Enjoy your ~3% niche OS.

Sorry, me and most people haven’t ever heard of your SaaS platform.

Then by any means, use Windows.

Never made that point. What I said is that NetBSD is a niche OS for hobbyists, and that if I wanted to run Linux software, instead of relying on emulation, I would rather just use Linux.

Enjoy your ~3% niche OS.

Did I hit a nerve here?

Anyway, funny that you would want to make that point when you yourself use NetBSD. You and the other five people running it on a desktop computer must be having a lot of fun I suppose.

Ok. Enjoy being where most people are (Microsoft 365?).

I will not do that. Because I don't care about what other people use. I want my software to make my life easier. If there are only three people alive who use a good software, I still wouldn't want to use worse software.

Name one Linux software that actually is "Linux software" in opposite to "Unix-like software" and/or "cross-platform software".

Did I hit a nerve here?

My laughing nerve is, indeed, somewhat sore now.

You and the other five people running it on a desktop computer must be having a lot of fun I suppose.

So your point is that you prefer mainstream software over good software? Are you sure that you don't use Windows?
