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.

Over the years the Free Software Foundation has certified various devices that to their standards "Respect Your Freedom" from USB to parallel printer cables to re-branded and re-flashed motherboards to the Talos II at the higher-end. They've also certified different network hardware and other devices. The newest that they announced today is backing a $99 mini VPN router that supports WireGuard and other solutions...

Further adding to the excitement of the upcoming Linux 6.4 merge window is the mainline kernel seeing the Device Tree (DT) additions for Apple's current M2 devices including the MacBook Air, MacBook Pro, and Mac Mini systems. The upstream kernel still has more work to go around the M1/M2 support compared to the downstream state with Asahi Linux, but at least now with this DT support will provide some basic level of upstream kernel support for the Apple M2...

Ubuntu 23.04 is being talked up for how it can aide developers that want to begin programming with Rust code for Linux kernel modules. It's possible to get started with Rust kernel development on Ubuntu 23.04 thanks to its generic kernel having the necessary kernel configuration, but ultimately it's still in an early state and there isn't much to do with the stock kernel...

Just two months after Zstd 1.5.4 was published, Zstd 1.5.5 has been released as the newest version of this Zstandard compression algorithm implementation. Zstd 1.5.5's release is motivated by addressing a rare corruption bug fix but also has various performance optimizations...

Among the many new features coming in Linux 6.3 -- including many AMD additions -- is the AMD P-State EPP "Energy Performance Preference" support being merged for modern Ryzen and EPYC systems. AMD P-State EPP can further help tune the performance and power efficiency of AMD Linux systems beyond the existing basic AMD P-State driver support and address some existing deficiencies. Here are some benchmarks of the AMD P-State and ACPI CPUFreq driver configurations benchmarked on an EPYC Milan-X server with the in-development Linux 6.3 kernel.

A rather profound change is pending for Mesa 23.1 that should lead to this OpenGL-on-Vulkan driver's memory utilization being cut in half for most games without negatively impacting the performance and likely closing a number of bugs in the process...
