A set of Linux kernel patches posted today by longtime Linux kernel developer Ingo Molnar are looking to remove support for "ancient" 32-bit CPUs. In particular, if these patches are accepted, the Linux kernel would be ending support for old i486 CPUs as well as early i586 CPU models...

Nearly two years ago patches for casefolding / case insensitive file and folder support on Bcachefs were posted by a Valve/Linux developer. That support was upstreamed into the Bcachefs kernel driver but it turns out that it never properly worked. Patches now set for merging into the Linux 6.15 will fix that case insensitive file/folder opt-in support so that it is now properly supported...

One of the interesting new features merged to the Linux kernel last year was the DRM Panic infrastructure so that Linux can display an error screen akin to Windows' "Blue Screen of Death" when encountering problems. With follow-on kernel releases it's been extended to add QR code error messages and other improvements. But DRM Panic does require the support/cooperation of the different Direct Rendering Manager drivers and so far Intel graphics haven't been supported...

Intel today released a new version of the Intel Extension for PyTorch in order to apply optimizations to PyTorch for benefiting Intel's hardware. With the Intel Extension for PyTorch v2.7 release, there is support for new large language models (LLMs) as well as various performance optimizations and other enhancements...

Following the COSMIC Alpha 6 release from February, System76 today released COSMIC Alpha 7 as their last planned alpha release for this open-source, Rust-written desktop environment designed around the needs of their Pop!_OS Linux distribution...

The Framework Laptop 13 with AMD Strix Point is now shipping that as detailed in our review earlier this month can provide for a very capable Linux laptop for Linux developers, creators, and enthusiasts. But for those hesitant about the high price and still weeks away before they have shipped all their pre-orders, if you are principally concerned about battery life, and/or after proven build quality backed by on-site warranty and other warranty/support options, the Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition ends up being a solid option for a very reliable and well-engineered laptop for Linux use. Here is a look at the Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition on Linux that is powered by Intel Lunar Lake.

A new software project covered on Phoronix last year was SCALE for natively compiling CUDA applications for AMD GPUs. This "clean room" implementation of CUDA building off the open-source LLVM codebase continues going strong and out this week is SCALE 1.3 with more features and hardware support for compiling CUDA software for AMD GPU execution...

Completely separate from the big performance regression I noted earlier this week for the Linux 6.15 Git kernel and fixed yesterday in the upstream codebase, another significant performance issue was also uncovered and fixed this week in Linux 6.15 Git...

New Linux kernel patches have been posted adding the necessary Device Tree files so that Linux is able to boot on the Qualcomm Snapdragon X1 powered Dell Inspiron 14 Plus laptop...

Mesa has supported on-disk shader cache for years to help speed-up game load times and overall system efficiencies. They had shifted from a multi-file cache layout to a single file cache for greater space savings. Steam also added support for the single-file cache. But now upstream Mesa is shifting back from the single-file cache default to the multi-file cache over performance issues...

At the end of last year the upstreaming efforts began for a Raspberry Pi HEVC decoder driver for getting H.265/HEVC accelerated decode working on the Raspberry Pi 4 and Raspberry Pi 5 single-board computers with the mainline kernel. Nearly a half-year later that effort is still ongoing but yesterday brought the third iteration of this driver...

The latest bit of hardware enablement coming out of Asahi Linux and queued for introduction in the mainline kernel the next cycle is PCI Express (PCIe) support for the Apple M2 Pro SoC...

AMD has published as open-source their "GPU-IOV Module" used for virtualization with Instinct accelerators. It's also reported on their roadmap for bringing virtualization support to their client (Radeon) discrete GPUs...

OpenMandriva Lx 6.0 Rock is now available with the KDE Plasma 6 desktop shipping by default while still offering both Wayland and X11 session options. There is also now an official server edition of OpenMandriva...

The Linux 6.15 kernel has just merged a fix for the big performance regression I spotlighted yesterday on Phoronix with a huge hit to the Nginx HTTPS web server performance that could see a 3x regression from the in-development Linux 6.15 kernel code. It turns out other workloads/applications also were negatively impacted by this regression. While a stumper at first even with the bisected commit, the issue was luckily resolved very quickly.

Mesa 25.1-rc2 is now available for testing as the newest weekly test version of this collection of OpenGL and Vulkan drivers. Mesa 25.1 continues working its way toward a stable release in May...

Earlier this month Canonical announced Ubuntu Linux support for the Orange Pi RV2 as a low-cost RISC-V developer board. The Orange Pi RV2 with eight RISC-V cores and 8GB of RAM costs just around $64 USD. The price point and specs were interesting that I ordered one and have been running performance benchmarks on it since for seeing how capable this is as finally an interesting, low-cost and readily available RISC-V board.

The newest open-source Linux driver being worked on by AMD engineers is a Remote Direct Memory Access (RDMA) solution for their Pensando networking hardware...

Back in March some ideas were talked about by Canonical engineers for Ubuntu Linux to move to Rust Coreutils and other Rust-written system components. Some of this is likely to materialize for the Ubuntu 25.10 release due out in October to allow for sufficient testing ahead of the all important Ubuntu 26.04 LTS release next year. Today the more solidified plans have been laid out for moving to the Rust Coreutils as a replacement to GNU Coreutils with Ubuntu 25.10...

Following a lot of work in this direction toward the end goal of removing GNOME X11 support, this milestone may finally be acheived for the Fedora 43 cycle due out by the end of the year. A change proposal has been filed for removing the GNOME X11 packages in the repository and in turn making the GNOME desktop Wayland-only on Fedora Linux...
