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’m sorry, but I have a bit more trust in the Linux kernel maintainers on the technicals of this issue than you or I.

I do know enough to know that a Cyril 6x86 is problematic to use with many modern applications. I find it hard to believe anyone using one needs a modern kernel feature for something, and any other PC is unavailable.

I mean, at the very least, I think they’d need another PC to build a custom kernel themselves? Can you even build Linux 7.1 on that system now?

Now I want to know how long it would take to compile, I might just set something up to find out.

…Acually, PM me or something if you do. I’m interested in that.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
