Ahead of the Linux 6.16 merge window opening up in just one month, the new Zblock allocator was queued up into Andrew Morton's "MM" tree of memory management material likely destined for the next kernel merge window. Zblock is showing much potential as a compressed slab memory allocator...

Tvrtko Ursulin of Igalia has been pursuing the Fair DRM Scheduler as a "fair" scheduling policy to help with multiple applications/processes aiming to make use of the GPU concurrently. With this week's v4 patch-set to the DRM Fair Scheduler there are some big code changes but overall looking well as a nice scheduling policy for multiple apps/games/processes wanting equal access to GPU resources...

With the Linux kernel now limiting 32-bit systems to 4GB of memory even with the "HIGHMEM" Kconfig option, an issue was uncovered where if the system was still populated with more memory than addressable by 32-bit systems, the kernel would crash. With the Linux 6.15-rc4 kernel due out on Sunday, this issue will be addressed...

A new Wayland-only feature merged for GNOME 49's Mutter is support for tablet pad relative dials. These dials found on some drawing tablets now allow for relative moment under the GNOME Wayland session when paired with recent libinput and libwacom releases...

As we near the end of April, KDE developers remain quite busy working on more enhancements for the Plasma 6.4 desktop while many of them were also meeting this week in Graz, Austria for further development and planning...

Following recent Vulkan 1.1 support within Mesa for the PanVK driver for open-source Arm Mali Vulkan driver support, Vulkan 1.2 is now being advertised...

This week Intel announced "200S Boost" for Core Ultra "Arrow Lake" K-Series desktop processors as effectively a new overclocking profile rolling out to existing Z890 motherboards via a BIOS update. Enabling the 200S Boost profile is said to help with low-latency workloads like gaming by allowing higher fabric / die-to-die / memory frequencies. While some Windows benchmarks have begun emerging for the Intel 200S Boost mode and some limited gains, I was curious about the performance under Linux so here are some 200S Boost benchmarks with the Core Ultra 9 285K on Ubuntu 25.04.

Linus Torvalds is sharing some of his classic and straight-to-the-point wisdom today over file-systems with case-folding / case-insensitive file and folder support...

While last week Intel released an update Compute Runtime for GPU compute with the OpenCL and Level Zero APIs on Windows and Linux, today they released a new preview version for readying a shiny new feature: Ultra Low Latency Scheduling "ULLS" for Lunar Lake Xe2 graphics...

GCC 15.1 was just released as the newest annual feature release to the GNU Compiler Collection. This first stable GCC 15 release brings a COBOL compiler front-end, many C and C++ language support improvements, support for new CPUs and ISA capabilities, better Rust programming language support, debugging enhancements, and a whole lot more...

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...
