With the set of today's AMDGPU kernel graphics driver Display Core (DC) patches is a rather curious addition with wiring up the Linux code to a "power module" that looks like it will better match Microsoft Windows behavior with the AMD Radeon driver around display-related power savings features...

The Linux 7.1 kernel is bringing performance improvements for Sheaves, the per-CPU caching layer introduced several kernel cycles ago (Linux 6.18) for better efficiency on today's high core count hardware. Sheaves began as an opt-in feature but since Linux 7.0 is now being used for all caches...

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.

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.

Last month we showcased GreenBoost as an open-source means of augmenting NVIDIA GPU vRAM with system RAM and NVMe storage. This memory tiering solution for NVIDIA GPUs was developed by an open-source developer with a focus on CUDA and allowing larger LLMs to be handled on graphics cards with smaller vRAM capacities. There was a setback to the project due to NVIDIA legal but now the project is going in new form and also has introduced GreenBoost-Proton for helping Linux gaming on NVIDIA hardware...

The Spack package manager is quite popular in the HPC / supercomputer space for scientific software. Even with the more selective niche than a typical general purpose OS package manager, large language models (LLMs) have already proven capable of being useful in generating new Spack packages. But there have also been some headaches involved too for Spack developers...

Last year NVIDIA announced the new CUDA Tile programming model as one of the biggest updates ever to the CUDA platform. CUDA Tile brings a virtual ISA for tile-based parallel programming and they subsequently open-sourced the CUDA Tile IR as an intermediate representation built atop LLVM's MLIR. Now they are looking to hire additional LLVM compiler engineers to help foster their CUDA Tile initiatives...

In advance of the Linux 7.1 merge window opening, Miguel Ojeda sent out all of the Rust feature updates on Friday.

For those wishing to make use of modern OpenCL 3.0 capabilities on AMD APUs/SoCs with integrated Radeon graphics using Mesa's Rusticl driver, an improvement was merged this weekend to the RadeonSI driver ahead of this quarter's Mesa 26.1 release...

Nearly one year ago to the day I noted Linux developers were considering the removal of the Apple HFS and HFS+ file-system drivers from the kernel. They were orphaned the past decade and turning into a maintenance burden for upstream developers. But then to some surprise, a few developers stepped up to maintain the HFS(+) drivers. One year later it's proving to be a success story with more fixes for this aging Apple file-system support continuing...

Among the early pull requests sent out to Linus Torvalds even before the Linux 7.0 kernel officially released on Sunday were the Btrfs file-system updates. This feature-packed CoW file-system is seeing more performance optimizations for Linux 7.1 as well as its shutdown ioctl feature no longer being experimental and a variety of fixes...

Building off last night's release of the Linux 7.0 kernel is now the GNU Linux-libre 7.0-gnu kernel release for that downstream kernel that removes support for loading non-free-software kernel modules, blocks the loading of loadable microcode/firmware even when it means greatly reduced hardware support, and other sanitization of code in the name of software freedom...

Merged for the Linux 7.0 kernel was a power sequencing driver for PCIe M.2 connectors as part of an effort to allow describing PCIe M.2 connectors in Device Tree files. For Linux 7.1, that driver is extending support for PCIe M.2 Key E connectors...

As expected the stable Linux 7.0 kernel was just released today in marking this next kernel release. The Linux 7.0 milestone comes due to Linus Torvalds' preference of bumping the major version number after hitting X.19 as opposed to any single major change, but in any event there are a lot of great improvements and changes to find with this new kernel version. Linux 7.0 is also what's powering the upcoming Ubuntu 26.04 LTS release...

An out-of-bounds access within the Linux kernel has existed in mainline the past three years that could be exploited by an unprivileged user submitting a specially crafted certificate to the kernel...
