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?

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.

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.
