Intel processors should have any CPU microcode updates loaded early during the Linux boot process to avoid various known issues. When "late loading" CPU microcode after the system is up and running, various issues can happen on Intel processors that led them to mark the Linux kernel as tainted under such conditions. Tainting the kernel also happened when late-loading microcode on AMD CPUs but now that's been deemed unnecessary and late-loading CPU microcode on AMD processors is reportedly safe...

Last month I wrote about Intel's Linux kernel engineering improvements to help enhance CPU scaling across various workloads by addressing low-level bottlenecks within the kernel. It's an area we'll likely see Intel continue to invest in as Sierra Forest comes next year with 144 E cores per socket. Already with the Linux kernel patches Intel is carrying at the moment via their in-house distribution, there are some significant benefits for Xeon Scalable Sapphire Rapids. I was curious to see how this Intel-focused work impacted AMD EPYC servers and thus in today's article is a similar analysis using two AMD EPYC 9654 "Genoa" flagship processors while evaluating Intel's Linux kernel optimizations.
