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?

There's probably a fortunate 500 company running some load bearing server from 20 years ago, that ends up back in production, everytime they fail to migrate the critical service away from it.

There must have been demand to keep x86 32bit alive this long.
