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?
No - nobody is still using one that would be running a modern distro. Anyone relying on hardware this old is already managing their own ecosystem of software.
We’re talking about computers that have clock speeds in the megahertz range FFS. They’re slower than an ESP32 and take a lot more power.
Nothing of value was lost.
