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?
Sir, I think you are overreacting. Nobody is running a 7+ Linux Kernel on a 486 machine. Even if you have microcontrollers with a 486 instruction set, I am pretty sure they already fixed the timestamp issue, or they don’t need Linux at all since it’s an embedded application.
