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 use NetBSD and never look back :)

The notion of using Linux to revive old hardware and keep it out of the landfill may not last forever…

Linux supports much less old hardware than its competitors.
