Linux Kills Ancient x86 Fallbacks

As Linux 7.2 makes the Time Stamp Counter mandatory, we look at why dropping legacy x86 fallback timing code is long overdue.

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?

      Sorry, me and most people haven’t ever heard of your SaaS platform.

      Ok. Enjoy being where most people are (Microsoft 365?).

      Then by any means, use Windows.

      I will not do that. Because I don’t care about what other people use. I want my software to make my life easier. If there are only three people alive who use a good software, I still wouldn’t want to use worse software.

      What I said is that NetBSD is a niche OS for hobbyists, and that if I wanted to run Linux software, instead of relying on emulation, I would rather just use Linux.

      Name one Linux software that actually is “Linux software” in opposite to “Unix-like software” and/or “cross-platform software”.

      Did I hit a nerve here?

      My laughing nerve is, indeed, somewhat sore now.

      You and the other five people running it on a desktop computer must be having a lot of fun I suppose.

      So your point is that you prefer mainstream software over good software? Are you sure that you don’t use Windows?
