It's "Patch Tuesday" and Intel is out with new CPU microcode for Linux users in addition to making public 30 new security advisories that affect a range of Intel products...

The Linux kernel's Human Interface Devices (HID) subsystem has an existing architectural limitation that there is just up to one battery per HID device. But with modern devices -- especially among various gaming peripherals -- there can be more than one battery when considering earbuds with a battery for each earbud, multi-device wireless receivers, etc. A proposal was raised today to address this limitation...

Lenovo recently sent over their new ThinkPad P1 Gen 8 laptop for review under Linux. My Linux review on that ThinkPad P1 Gen 8 laptop will be coming up in the near future along with some other benchmarks from that premium mobile workstation. But with this being the first time I've had an Intel Core Ultra 7 255H "Arrow Lake H" device at Phoronix, here are some standalone benchmarks looking at the CPU performance of that 16-core mobile processor compared to various other Intel and AMD SoCs in different laptops while running Ubuntu Linux.

While there is the AMD openSIL project for open-source CPU silicon initialization for platforms moving forward with plans to ultimately replace AGESA and be more friendly toward the likes of Coreboot, for those on aging AMD Bulldozer and Piledriver era platforms there is some updated open-source firmware available thanks to an independent free software project...

Společnost QNAP Systems uvedla na trh nový výkonný NAS pro vysokorychlostní ukládání dat a spolehlivé zálohování. Model TS-h2477AXU-RP nabízí 24 pozic pro 3,5“ disky SATA a dva sloty PCIe Gen 5 M.2 SSD pro zpracování velkých objemů dat a ultra rychlý přístup k datům.

Intel on Monday released version 0.1 of their Low Power Mode Daemon, the open-source daemon in development for several years now for optimizing active idle power on modern Intel Core (Ultra) CPUs under Linux...

System76 engineer Victoria Brekenfeld and Red Hat engineer Sebastian Wick presented at the recent XDC2025 developer conference with their hopes of finally fixing the multi-GPU experience on Linux. As part of this is getting the necessary Wayland protocols in order as well as a new gpu-daemon service for proper multi-GPU handling for the Linux desktop...

New Linux kernel patches currently undergoing review will allow AMD Ryzen AI NPU power metrics to be exposed under Linux. In turn this is useful for helping to gauge the utilization of the neural processing unit and also helping to evaluate the actual power efficiency of leveraging the AMD Ryzen AI NPU...

The YouTube video recordings for the X.Org Developers' Conference 2025 that took place at the end of September in Austria are finally available. Among the many interesting XDC2025 presentations was Intel engineer Matthew Brost talking about the GPU Shared Virtual Memory (SVM) within Intel's modern Xe kernel graphics driver...

The SDL3 library that is popular with cross-platform games for abstracting various software/hardware features has implemented render batching for its built-in rendering API. This render batching is successfully wired up now for Direct3D 11/12, Apple Metal, and Vulkan APIs for more efficient graphics rendering...

While there is already AMDXDNA as one of the few currently mainline drivers in the accelerator "accel" subsystem for supporting AMD Ryzen AI NPUs, another AMD accel driver is on the way: amd_vpci. The new amd_vpci driver patches were posted today for review as AMD continues to further expand their diverse offerings in the ecosystem...

První listopadový víkend proběhl v Brně tradiční OpenAlt. Mluvilo se o hrozbách v open-source ekosystému, simulátoru dispečinku metra, řešení domácího nabíjení elektromobilů a zkušenosti s energetickým trhem.

Seznámíme se s technologiemi, na kterých je založen formát WebAssembly. Tento formát umožňuje spouštění aplikací v rámci webových prohlížečů popř. na serverech nebo jako součást složitějších aplikací uvnitř takzvaného sandboxu.

EasyEffects is the open-source application formerly known as PulseEffects that transitioned to using native PipeWire filters for providing simple audio effects on the Linux desktop. EasyEffects makes it easy to apply different audio effects like bass enhancer, compressor, pitch shift, reverberation, and many more. With this week's release of EasyEffects 8.0, the user interface has been rewritten in Qt / QML / Kirigami rather than GTK4...

Following yesterday's release of Rust Coreutils 0.4, GNU Coreutils 9.9 is now available as the latest update to this set of core utilities common to Linux systems and other platforms...

Google Cloud today is rolling out their N4D compute instances that are optimized for cost/price-performance and geared for general purpose workloads. The N4D instances are powered by 5th Gen AMD EPYC "Turin" processors and offer very nice performance and value over their prior-generation general purpose VMs.

MX Linux je ďalšou distribúciou, ktorá preberá novinky z Debianu 13. Nová verzia MX Linuxu 25 pridala aj rôzne iné zaujímavé zmeny, napríklad podporu pre Secure Boot či predvolený Wayland v prostredí KDE Plasma.

Last week when delivering some CachyOS benchmarks against Fedora 43 and Ubuntu 25.10 on the Framework Desktop with AMD Ryzen AI Max+, a few Phoronix readers wrote in with the question or belief that openSUSE Tumbleweed would better perform against CachyOS given the distribution's select x86_64-v3 packages and other advantages. As it's been a while since running any benchmarks of the rolling-release openSUSE Tumbleweed, here are those benchmarks now in the mix for seeing how the performance compares.

Firefox 145 release binaries are now available. Most notable with this release is what's not there: the 32-bit Linux builds are no more...

Whenever seeing Linux kernel mailing list patches from Google engineer Eric Biggers it tends to be about performance optimizations to the Linux kernel's cryptography subsystem. That was once again the case on Sunday with the newest patch series providing some nice gains...
