Silly Open-Source Moves, AMD openSIL & Rust Happenings Made For An Interesting Month

Written by Michael Larabel in Phoronix on 30 April 2023 at 09:11 PM EDT. 1 Comment
During this month on Phoronix were 242 news articles on Phoronix with original content each and every day presented by your's truly around open-source and Linux. April was interesting with the release of Linux 6.3, all of the exciting Linux 6.4 features merged so far, AMD introducing openSIL for open-source CPU silicon initialization with support for Coreboot and similar firmware solutions, Fedora 38 and Ubuntu 23.04 being released, and much more.

For as exciting as April was on both the hardware and software fronts, operations at Phoronix unfortunately remain difficult due to the macro environment, the continued depressed state of advertisements on the web, and so many open-source/Linux enthusiasts happily using ad-blockers. The widespread use of ad-blocking continues to make operations sadly only more difficult, especially for delivering quality content. Aside from disabling ad-blockers, you can show your support by joining Phoronix Premium to view the site ad-free, multi-page articles rendered on a single page, native dark mode support, and other features all while helping to ensure Phoronix can see for a successful new birthday year with set to turn 19 in June.

With that said, for the most popular news on Phoronix during April 2023 on Phoronix included:

Linux 6.4 Bringing Apple M2 Additions For 2022 MacBook Air, MacBook Pro, Mac Mini
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.

AMD openSIL Detailed For Advancing Open-Source System Firmware
Open-source fans, rejoice, the most exciting thing I have read all week or perhaps the month: "AMD is committed to open-source software and is now expanding into the various firmware domains with the re-architecture of its x86 AGESA FW stack - designed with UEFI as the host firmware that prevented scaling, to other host firmware solutions such as coreboot, oreboot, FortiBIOS, Project Mu and others. A newer, open architecture that potentially allows for reduced attack surface, and perceivably infinite scalability is now available as a Proof-of-Concept, within the open-source community for evaluation, called the AMD openSIL – Open-Source Silicon Initialization Library."

Intel Linux Optimizations Help AMD EPYC "Genoa" Improve Scaling To 384 Threads
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.

Windows 11 WSL2 Performance vs. Ubuntu Linux With The AMD Ryzen 7 7800X3D
When carrying out the recent Windows 11 vs. Ubuntu 23.04 benchmarks with the AMD Ryzen 7 7800X3D Zen 4 3D V-Cache desktop processor, I also took the opportunity with the Windows 11 install around to check in on the Windows 11 WSL2 performance.
