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.
