Hector Martin who has been leading the Asahi Linux effort for bringing up Linux on Apple Silicon recently received his new 2022 MacBook Pro 13-inch to begin porting Linux to Apple's new M2 SoC. While only started this week, he's already making significant progress. Fortunately, much of the existing M1-written Linux code can work for the M2 but some new drivers will need to be written before the new M2 Macs are fully usable on Linux...

With last week seeing AMDVLK 2022.Q2.3 released as an update to AMD's official open-source Vulkan Linux driver and it noting performance improvements, it was time for some fresh benchmarks of that driver up against Mesa's alternative "RADV" Vulkan driver. Here are some fresh benchmarks with an AMD RDNA2 GPU for seeing how RADV continues competing -- and usually outperforming -- AMD's own official open-source driver.

A "sched/fair" scheduler change queued this morning into TIP's sched/core for Linux 5.20 aims to enhance the efficiency when searching for an idle CPU under heavy system load. The change led by Intel should improve the kernel's efficiency when the system is overloaded but as with most low-level tuning does run the risk of regressions...

Last month for their Vision conference, Intel announced the Habana Labs Gaudi2 accelerator. Gaudi2 is the second-generation offering from Intel-owned Habana Labs for training and inference.

The Rust-GCC front-end that allows Rust code to be compiled with the GNU Compiler Collection (GCC) could possibly be upstreamed for next year's GCC 13 compiler release but not necessarily complete at that stage.

Coming about last week was a Fedora 37 change proposal to improve the profiling and debugging of Fedora packages but with possible performance costs. That suggested change is about adding "-fno-omit-frame-pointer" to the default CFLAGS/CXXFLAGS when building packages so the frame pointer is always available for improving the debugging/profiling of the stock Fedora packages. Unfortunately, it can come with significant performance costs as these benchmarks show.

2022 is certainly looking to be interesting on the open-source graphics driver front... You probably didn't have Imagination publishing an open-source PowerVR Vulkan driver on your 2022 bingo card nor NVIDIA working on an open-source GPU kernel driver. The latest 2022 surprise is the OpenChrome driver project is hoping to finally be mainlined in Linux 5.20 for open-source VIA graphics for those still running vintage VIA x86 hardware...

Intel's open-source Linux graphics driver developers remain very busy preparing the open-source driver stack for Arc Graphics DG2/Alchemist hardware.

One of the great defaults when installing Pop!_OS or receiving a pre-loaded laptop/desktop from System76 or the new HP Dev One is that it encourages full-disk encryption and prominently shown during the install process. I highly recommend full-disk encryption especially for laptops. As it's been a few years since running benchmarks looking at the overhead of LUKS encryption, here are some benchmarks of Pop!_OS 22.04 on the HP Dev One with the full disk encryption enabled and then a fresh install without encryption.

While many Red Hat open-source projects end up being relatively instant successes that then end up being widely adopted in the open-source community, Red Hat's Stratis Storage effort seems to be trending as one of the exceptions. Red Hat continues investing in Stratis but it doesn't seem to have the sizable adoption or widespread interest that tends to come with most of their projects. In any event, Fedora 37 later this year should ship with the newest Stratis tech...

With the recent release of Ubuntu 22.04 LTS it is shipping systemd-oomd by default on their desktop for trying to better handle low-memory / out-of-memory situations. However, in real-world use systemd-oomd is too easily killing user-space applications like Firefox and Chrome when approaching memory pressure. This is a poor Ubuntu 22.04 user experience but the developers now have an idea for their approach to addressing this solution...

After months of using Starlink and carrying out thousands of benchmarks, Starlink in the US midwest / Chicagoland area has proven reliable but the performance can be rather volatile still and it was frustrating at first waiting for some Starlink accessories to ship, but the self-service nature and simplicity of the setup were great.

This week though AMD did post a new patch for Blender enabling HIP support on Windows and Linux for Vega/GFX9 graphics...
