A set of 14 patches were merged today to the Mesa 3D graphics driver codebase for fixing some wide-reaching performance issues that would have negatively affected the upcoming Xe3 integrated graphics with Core Ultra Series 3 "Panther Lake" hardware. The patches have been merged so will be very important that anyone buying an upcoming Intel Panther Lake laptop move to using an up-to-date Mesa to avoid these performance problems.

Intel engineer Francisco Jerez began the recent merge request with:

"This series addresses a number of

Hyprland 0.51 is now available as the latest feature release for this unique Wayland compositor.

Hyprland 0.51 bring a reworked gesture system is that is much more flexible than the prior implementation. There is also reworked trackpad gestures with Hypyrland 0.51 that includes now being able to set new 1:1 gestures for fingers / modifiers / directions.

Hyprland 0.51 also brings new configuration options, the scroll factor can be set for per-device configurations, new DPMS animations, fade in

The Zink OpenGL-on-Vulkan driver is well optimized for Linux gaming and desktop use thanks to the work by Mike Blumenkrantz being funded by Valve. Zink has even worked with OpenCL thanks to Rusticl and now another frontier is being conquered for this generic OpenGL on Vulkan driver: workstation graphics with optimizing around the SPECViewPerf test cases.

Mike Blumenkrantz on Valve's great Linux team has been working recently on optimizing the Zink OpenGL-on-Vulkan driver code around SPECViewPerf test cases.

Without optimizations, he was hitting aorund 1

Pogocache is the open-source fast caching software built from scratch that is optimized for low latency and CPU scalability/efficiency. Pogocache claims to outperform Memcached, Valkey, Redis, and other alternatives . Out today is Pogocache 1.2 as the newest feature release for this fast cache.

Pogocache 1.2 adds optional jemalloc support for those wanting to build with that performant memory allocator. Microsoft's mimalloc general purpose allocator is also now supported as the default allocator. Mimalloc is said to provide "excellent" performance for

Linux kernel developers are evaluating the idea of removing HIGHPTE support from the Linux kernel due to its maintenance burden and just one ARM system currently using it.

Linux's HIGHPTE support pre-dates 64-bit support and was used for helping ARM achieve feature parity with 32-bit x86 systems. HIGHPTE allows for user-space second-level page tables to reside within high memory. But when it comes to the mainline kernel support, ARM is the last one still supporting HIGHPTE for 32-

The newest Direct Rendering Manager (DRM) display driver that has been in the works for the Linux kernel is "Yhgch" from Inspur.

Major Chinese ODM Inspur has been working on this Yhgch DRM driver for the Linux kernel. Yhgch is for an Inspur SoC/BMC chipset but details beyond that are light.

So far I haven't been able to turn up any information on this Yhgch Baseboard Management Controller (BMC) so it would appear to either be a placeholder name or for an unreleased product.

Following the numerous Intel Linux developer departures last month from the company following layoffs at Intel and others deciding to voluntarily leave, there is another one to report today. One of the Intel IVPU accelerator driver maintainers for the Intel NPUs found in Core Ultra SoCs is departing the company.

The staffing challenges at Intel have led to various Linux driver maintainer changes and even some drivers being orphaned as a result . One of the Intel IVPU/NPU driver maintainers announced publicly today he is leaving Intel but at least there are two other existing

For those preferring for the first point release to major new compiler releases before upgrading, LLVM 21.1.1 is out today along with the likes of Clang 21.1.1 for this widely-used open-source compiler stack.

LLVM 21.1 released in late August with many significant improvements and other enhancements as the newest half-year feature release to LLVM. In going off their typical bi-weekly point release regiment, LLVM 21.1.1 is now available.
