WQ_AFFN_CACHE_SHARD Merged For Linux 7.1: Significant Win For CPUs With Many Cores Per LLC

15 avril 2026 à 19:55
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...

Linux 7.1 Is A Big Win For Intel Panther Lake With FRED Now Enabled By Default

15 avril 2026 à 18:05
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...

Intel Arc Pro B70 Open-Source Linux Performance Against NVIDIA RTX & AMD Radeon AI PRO

15 avril 2026 à 17:00
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.

Sched QoS For Linux Aims To Improve Scheduling & Inspired In Part By Apple's QoS Classes

15 avril 2026 à 13:18
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...

Patches For Linux 7.1 May Have Negative Impact On 32-bit Systems

14 avril 2026 à 20:21
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...

Ubuntu 26.04 Delivers Great Performance Improvements For AMD Strix Point, Especially For RDNA 3.5 Graphics

14 avril 2026 à 17:22
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.
