The workqueue changes merged today for the Linux 7.1 kernel are significant for today's modern high-end processors where there can be many CPU cores per last level cache (LLC / L3 cache). The new WQ_AFFN_CACHE_SHARD affinity scope can reduce some contention on such systems and help achieve greater performance...

Archinstall 4.2 is now available as the latest update to this very convenient, text-based Arch Linux OS installer...

Last month I ran benchmarks showing the very positive performance impact FRED has on Intel's new Panther Lake processors while wondering why Flexible Return and Event Deliver wasn't enabled by default yet on Linux. Hours after that story was published, an Intel engineer posted the patch to enable FRED by default with the rationale they were waiting for hardware to be publicly released in order to evaluate the performance benefit. Days after that the FRED-by-default patch hit tip/tip.git and now as of yesterday that patch is merged for Linux 7.1...

Last week after receiving the Intel Arc Pro B70 review hardware I began with some benchmarks looking at how the Arc Pro B70 compared to existing Intel GPUs on Linux with their fully open-source driver stack. Today's article features the latest Arc Pro B70 benchmarks under Linux in looking at how the performance and value compares to other NVIDIA RTX and AMD Radeon (AI) PRO workstation graphics cards in the lab.

Eric Engestrom stepped up again to serve as Mesa release manager for this quarter's Mesa 26.1 feature release. Mesa 26.1-rc1 was just released in kicking off the weekly release candidate dance until Mesa 26.1 stable is ready for debut in May...

A change proposal has been filed to build x86_64-v3 micro-architecture feature level packages alongside the existing x86_64-v1 packages for Fedora Linux...

Linux developer Qais Yousef with Google has announced the alpha release of Sched QoS as a new initiative for user-space assisted scheduling. The scheduling model in turn is based in part on Apple's quality of service classes used by iOS for classifying software as user interactive, user initiative, utility, or background tasks...

As a follow-up to the news first-covered on Phoronix earlier this month about Linux 7.1 expected to begin removing i486 CPU support: it indeed happened. Linus Torvalds took the initial removal bits today without any fuss today for beginning the phase out of M486 / M486SX / ELAN kernel support...

ROCm 7.2.2 is out today as a small point release to this open-source AMD GPU compute stack. There are a few code changes but most notable is arguably on the documentation side...

Pingora je framework napsaný v jazyce Rust, který slouží v Cloudflare jako reverzní proxy. Byl uvolněn pod svobodnou licencí, takže jej může použít každý. Povíme si o typických scénářích použití.

Zanalyzujeme výkon procesů pomocí trasování, zautomatizujeme vypínání serverů i virtuálních strojů při výpadku proudu, budeme monitorovat síťový provoz aplikací a izolujeme nedůvěryhodný kód v bezpečném sandboxu.

Code now merged for the Linux 7.1 kernel may provide some negative performance implications for those still running modern Linux kernels on 32-bit hardware. A fundamental change can present cache line alignment and slab sizing implications for 32-bit Linux OS users but will provide for cleaner code with modern 64-bit computing...

While a lot of interesting new features and changes have been merged already for the Linux 7.1 merge window, two pull requests stand out so far for being rejected by Linus Torvalds and complete with his to-the-point commentary...

As part of my ongoing testing around the upcoming Ubuntu 26.04 release I have been running a lot of benchmarks. After recently showing some nice performance gains for AMD Ryzen AI Max "Strix Halo" with Ubuntu 26.04, several Phoronix readers inquired about any performance uplift from the more modest but still powerful Strix Point laptops like the popular Ryzen AI 9 HX 370 SKU. Here are benchmarks showing the performance of Ubuntu 26.04 in its near final state compared to Ubuntu 24.04.4 LTS with its HWE stack on an ASUS Zenbook S16.
