Recently there was an LLVM bug report of "Worse runtime performance on Zen CPU when optimizing for Zen." Well, that's not good... Fortunately, that bug is now fixed with the latest LLVM Clang compiler code but other deficiencies in the AMD CPU optimization targeting remain...

If all goes well the Linux 6.9 stable kernel will be released on Sunday and in turn mark the opening of the Linux 6.10 merge window. In hoping for an on-time release, some Linux kernel subsystem maintainers have been already submitting early pull requests of their feature material for v6.10. Among those early pulls are the SLAB (SLUB) updates...

A new patch series sent out today by AMD Linux engineers confirm that PCIe TPH will be supported with "upcoming AMD hardware" as a nice performance optimization feature for PCI Express...

While Canonical has been investing more into the performance of Ubuntu Linux and engaged some new performance improvements in Ubuntu 24.04 LTS, it's still not the fastest Linux distribution out there on x86_64 hardware. Similarly, the recently released Fedora Workstation 40 features the brand new GCC 14 compiler and other leading-edge open-source software packages, but there's still more performance left on the table as shown by Intel. Here are some fresh benchmarks looking at how Ubuntu 24.04 LTS and Fedora Workstation 40 are competing with Intel's in-house Clear Linux distribution that offers aggressive x86_64 Linux performance defaults and the best possible out-of-the-box Linux performance on modern x86_64 hardware.

As expected, AMD today published the Micro Engine Scheduler "MES" firmware documentation for RDNA3 graphics processors as part of better engaging with the open-source community and aiming to address some gaps in their open-source GPU compute stack...

In addition to a Framework Laptop EC driver being prepared for Linux that extends the Chrome OS embedded controller (EC) used by recent Framework Laptops, a ChromeOS EC hardware monitoring (HWMON subsystem) driver has also been revived as a further support extension for Framework laptops on Linux...

The Intel iVPU accelerator driver changes for the upcoming Linux 6.10 merge window have been submitted for advancing the Neural Processing Unit (NPU) support found since the launch of Meteor Lake with Intel Core Ultra notebook CPUs. For this iVPU/NPU driver in Linux 6.10 are a few notable new features...

The AMDGPU Linux kernel graphics driver has seen a new patch series preparing enablement of a new hardware intellectual property (IP) block for the first time: the ISP...

Ongoing Mesa release manager Eric Engestrom continues carrying out a splendid job with the on-time releases of new bi-weekly Mesa point releases and the weekly release candidates heading toward the next feature release of these open-source predominantly OpenGL and Vulkan drivers...

Back in January the Zed editor was open-sourced for this new code editor from the creators of the Atom editor and Tree-sitter syntax parsing framework. This high performance code editor has been initially focused on macOS support while the Linux support has begun coming together...

Since last year Intel's open-source software engineers have been working on a PCIe bandwidth controller driver for the Linux kernel to avoid thermal issues by being able to automatically reduce the PCIe link speed when needed. This driver still isn't over the finish line but today brought the fifth iteration of these patches...

Recently I've been testing out the Scaleway's Elastic Metal RV1 (EM-RV1) RISC-V cloud servers. Initially they were using Ubuntu 23.10 for providing an up-to-date Ubuntu Linux RISC-V experience while quickly upgraded to Ubuntu 24.04 LTS. For those curious how Ubuntu 24.04 is performing on RISC-V hardware, here are some comparison benchmarks.

Building off the recent release of Fedora 40, Fedora Asahi Remix 40 is now available for this downstream of Fedora Linux that's optimized to run on Apple Silicon ARM systems...
