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 :)
Linux supports much less old hardware than its competitors.
I don’t know why you’re getting downvoted?
NetBSD
OpenBSD
On the other hand, Linux runs more software than its competitors, and it’s not even close.
But NetBSD and FreeBSD can run Linux software as well?
