Being worked on since last year by Google engineer Roman Gushchin was the latest attempt for the Linux kernel to support managing the out-of-memory "OOM" behavior using BPF programs. It's been a while since there has been anything new to report on that front but published overnight is the latest iteration of those patches...

Keith Packard published Picolibc 1.8.11 on Monday as the newest release for his C library designed for embedded 32-bit and 64-bit platforms. Picolibc continues tacking on new CPU architecture support and other features for this project that started out as a conglomeration of the Newlib and AVR Libc C library codebases...

AMD's RadeonSI Gallium3D driver for next quarter's Mesa 26.1 release is introducing a new low-latency video decode mode. This lower-latency video decoding comes with a trade-off of increased GPU power consumption...

V pátém článku o tvorbě GUI s využitím knihovny Kivy nejprve dokončíme popis kontejnerů, které tato knihovna vývojářům nabízí. Následně se budeme zabývat způsobem využití takzvaného kreslicího plátna (canvasu).

Compiler profile guided optimization (PGO) techniques have paid off well for increasing CPU performance via application/workload-specific profiles fed back to the compiler to make more informed decisions. AMD compiler engineers have been working on crafting device-side PGO for their AMDGPU LLVM back-end for allowing ROCm/HIP workloads to achieve greater GPU performance. An initial merge request is now open for upstream LLVM...

The latest Firefox Nightly builds have now enabled the Split View mode by default to easily view two web pages at once within a single window...

Ahead of tomorrow's official availability of new Intel Core Ultra Series 3 "Panther Lake" laptops, the review embargo lifted on Panther Lake and its much anticipated Arc B390 graphics. There have been several Windows 11 reviews of Panther Lake out today, but what about Linux?..

Distribúcia MX Linux má dostupné nové inštalačné obrazy s aktualizáciami softvérových balíčkov. Tieto obrazy už zároveň nie sú rozdelené podľa dostupných init systémov a obnovená bola podpora pre dual-init.

Back at the start of the Linux 6.19 kernel cycle I ran benchmarks showing some scheduler performance regressions with the new kernel. Fortunately, two weeks out from the Linux 6.19 stable release, merged this weekend was disabling the scheduler's NEXT_BUDDY feature due to performance regressions. Here are some fresh benchmarks looking at the latest Linux 6.19 Git state with/without NEXT_BUDDY and comparing it to Linux 6.18 stable for reference.

A patch causing a healthy technical debate today on the Linux kernel mailing list would allow the kernel virtual terminal "VT" support to be enabled/disabled at boot time rather than being limited to the current CONFIG_VT build-time option...

Added to the LLVM 23 Git codebase minutes ago is a pull request adding the initial AMDGPU GFX13 target for their next-generation graphics core IP. AMD GFX13 is presumably for RDNA5...

A patch series posted last week for the open-source AMDGPU kernel driver implements HDMI Variable Rate Refresh "VRR" and other gaming features for HDMI displays. With the HDMI Forum blocking HDMI 2.1 open-source support, these HDMI gaming features for the AMDGPU driver were developed via trial-and-error and the limited public knowledge available. A second iteration of these patches are now available for testing...

For the Intel-powered LG Gram Style 14 laptop one of the Linux support caveats is the internal speakers not working properly under Linux, but with a patch expected for the upcoming Linux 6.20~7.0 kernel cycle it will finally fix the laptop speaker support for one of the laptop models in this series...

ASRock Rack's PAUL is a low-profile PCIe IPMI card built around the widely-used ASPEED AST2500 controller for providing IPMI/BMC capabilities for any platform. New patches provide mainline Linux kernel support for ASRock Rack PAUL with the necessary Device Tree bits...

Kairui Song of Tencent sent out a new patch series overnight working on enhancing the Linux kernel's swap code. With the patches there are some memory savings -- and more on the way -- while also providing for slightly faster performance...

While we wait to see what comes of the new X.Org Server Git branch plans and a possible X.Org Server 26.1 release, several X.Org libraries saw new point releases this weekend. These seldom-updated libraries saw new releases to ship various build fixes and other minor improvements...
