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?
Why on earth you are still relying on 30+ year old CPU’s? Are you a supermarket owner on a third world country?
Some people are.
Maybe, but I think that they will not upgrade the system, even without this change there is no reason to use a 7.x kernel on a 30+ Yeats old hardware
I’m pretty sure any Rpi is more powerful, smaller, and more efficient than any computer hardware from 30 years ago lol.
True, but imagine the cost of having to set that up as a third world market owner
