Intel's Linux OS Shows The Importance Of Software Optimizations, Further Optimized Xeon "Ice Lake" In 2021

As part of the various end-of-year Linux comparisons that I've made a habit of over the past 17 years, with the EOY 2021 benchmarking I was rather curious to see how Intel's Clear Linux distribution has evolved Xeon Scalable "Ice Lake" performance since that platform launched in Q2'2021. It turns out there have been some terrific optimizations squeezed out of that latest-generation Xeon Scalable platform on Intel's Clear Linux. In this article is a look at the Ubuntu and Clear Linux performance on the flagship Xeon Platinum 8380 2P reference server back around the time Ice Lake launched and then again using the latest software packages that closed out 2021.

But that AMX bring-up is more invasive than when introducing AVX as with AMX the feature needs to be "requested" for use by user-space, among other changes. As such extra handling also needed to be introduced for the Kernel-based Virtual Machine (KVM) that hadn't made it for v5.16 but now it looks like the AMX KVM support may be ready for mainline...

Fortunately, that's largely a thing of the past and Fedora 36 is looking to remove support for those legacy network configuration files from new Fedora installs...
