Intel software engineers are responsible for many of the great x86_64-related optimizations to the GNU C Library "glibc" over the years. While they've extensively tuned many Glibc functions for achieving peak performance on their modern CPUs, it's a never-ending quest. Merged this week was another optimization to strnlen(), the function for determining the number of bytes in a fixed-size string.

LibreOffice 24.8 is officially out today as the latest major feature update to this open-source office suite that's the leading free software alternative to Microsoft Office. With LibreOffice 24.8 comes many new features throughout its various components.

Google has promoted Chrome 128 to its stable channel across macOS, Windows, and Linux platforms.

Intel's uncore Linux platform driver is preparing for a new feature found on newer SoCs: ELC, or Efficiency Latency Control. This ELC feature for the Intel uncore handling allows fine tuning efficiency versus latency characteristics.

As part of Intel's Scalable Video Technology (SVT) initiative they had been developing SVT-HEVC as a BSD-licensed high performance H.265/HEVC video encoder optimized for Xeon Scalable and Xeon D processors. But recently they've changed course and the project has been officially discontinued.

This week marks nine years since the Linux Vendor Firmware Service (LVFS) was started by Richard Hughes of Red Hat to ease the firmware updating/distribution process with the open-source Fwupd firmware updating utility.

Building off the prior NVIDIA 560 beta driver releases, the NVIDIA 560.35.03 stable Linux driver was released today for providing the latest official NVIDIA graphics/compute support for Linux systems.

Google engineer Qais Yousef has posted a set of 16 patches for the "Schedutil" scheduler utilization code within the Linux kernel to better manage system response time. Schedutil is often used by default on many Linux distributions and with these patches a popular web browser benchmark can be as much as 30% faster with these kernel patches.

Following all of the Snapdragon X1 upstream enablement work over the past number of months by Qualcomm and then DeviceTree additions emerging for enabling the likes of the ASUS Vivobook S 15, Lenovo Yoga Slim 7x, Lenovo ThinkPad T14s Gen 6, and Microsoft Surface 7, the Samsung Galaxy Book4 Edge is the newest Snapdragon X1 Elite laptop seeing Linux DT support.

Zed, the code/text editor being developed by former Atom editor developers, has continued to gain interest among developers since going open-source, being written in the Rust programming language, and native Linux builds taking shape. The latest feature work on Zed is beginning to integrate AI-powered functionality by leveraging Anthropic's Claude LLM.

SVT-AV1 2.2 is now available for this leading open-source AV1 video encoder. With this new version comes yet more performance optimizations.

Released last month was the VirtualBox 7.1 Beta 1 virtualization software release from Oracle. This new version is bringing a modernized GUI, Wayland clipboard sharing, and other improvements. Released yesterday was the second beta of this big VirtualBox update.

Today marks the beginning of the string freeze for the long-awaited GIMP 3.0 open-source image editor release as one of the leading free software alternatives to Adobe Photoshop.

Andrea della Porta of SUSE has been working on upstreaming the Linux kernel support to boot the Raspberry Pi 5 on a mainline kernel. Over the past few months Andrea has posted a number of different patches derived in part from Raspberry Pi's downstream kernel code. The latest effort being pursued by the SUSE engineer is on upstreaming Raspberry Pi RP1 PCI device support using a DeviceTree overlay.

As part of my ongoing AMD Ryzen 9 9950X Linux testing, last week I provided a look at the AVX-512 benefits to Zen 5 and also the Windows vs. Linux performance for the Ryzen 9 9950X. For sharing today is a look at multiple Linux distributions up and running on the AMD Ryzen 9 9950X (Zen 5) desktop. Among the distributions in the mix are Intel's Clear Linux distribution that is optimally tuned for maximum x86_64 Linux performance and once again even on AMD hardware shows the significant benefits to a well-tuned Linux software stack.

Queued yesterday into the Linux power management subsystem's "linux-next" branch ahead of the Linux 6.12 kernel are some important additions for Intel processors and also an important fix for AMD processors to enjoy package power monitoring.

While the Unigine SDK these days is more known for its simulation and engineering offerings rather than as a game engine, this engine remains visually impressive and continues advancing. Unigine 2.19 has been released that brings a number of improvements to the engine and leaves us clamoring to see a new/updated benchmark.

There are a few interesting bits of information as part of this week's updates from the Ubuntu Desktop Team Integration Squad.

LunarG engineer Aitor Camacho Larrondo has proposed VK_EXT_external_memory_metal, a new extension for the Vulkan API to allow for more easily sharing memory objects from Vulkan with Apple's Metal.

A new batch of HID subsystem fixes were merged today for the ongoing Linux 6.11 kernel development.
