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?

I have some xeons in an old server running that I can't update to the next version of Rocky because the kernel won't support them :(

Isn't that just Rocky configuring the kernel that way? You're free to compile your own kernel and it'll still support even old pentiums, just not i486 in new versions
