14 May 08:46 PM EDT - Valve - SDL + Steam Controller 2026

Valve's new Steam Controller, which began shipping earlier this month for $99 USD, is a great piece of hardware. This high-end gaming controller is great hardware wise but what some may not enjoy about it currently is the tight integration with the Steam controller and no native OS drivers currently for use outside of Steam. As a big win today, the widely-used SDL3 gaming software/hardware abstraction library has added support for the new Steam Controller that works outside the confines of Steam.

14 May 06:46 PM EDT - AMD - AMD P-State Dynamic EPP

Dynamic EPP is one of the new AMD P-State features in Linux 7.1, but, unfortunately is causing some fallout in early usage of this power-savings related functionality.

14 May 01:32 PM EDT - KDE - KDE Plasma Big Screen

With today's KDE Plasma 6.7 beta release there has been a surprising amount of interest in the new revival of Plasma Big Screen as the TV-sized UI for Plasma. I've been trying it out today and it has worked out rather well, a very smooth experience, and in good shape for making its debut in next month's Plasma 6.7 release.

One of the latest Linux gaming handheld drivers being worked on is the MSI Claw Configuration Driver for controller configuration.

With the new System76 Thelio Major workstation review unit having arrived equipped with an AMD Radeon AI PRO R9700 graphics card, I took the opportunity of having the extra RDNA4 workstation GPU to satisfy a curiosity over whether there has been any meaningful performance gains from ROCm 7.0.0 released last year to now with the latest ROCm 7.2.3 stable release. Here are those benchmarks results if you are curious about the impact of just updating the user-space ROCm components from the end of last summer to the latest ROCm 7.2.3 milestone.

Since March we have been seeing patches from AMD software engineers beginning to enable their next-generation "AIE4" NPU platform under Linux. We still don't know for sure when this AIE4 NPU will premiere for sure in new Ryzen AI products, but the Linux enablement continues coming along nicely for the AMDXDNA accelerator driver.

14 May 08:23 AM EDT - Intel - Cache Aware Scheduling

I have been writing about the Cache Aware Scheduling work led by Intel engineers on the Linux kernel for more than a year. I've also tested out Cache Aware Scheduling on both Intel and AMD CPUs with the patched Linux kernel to great success. And thus very happy to see the Cache Aware Scheduling patches inching closer to the mainline Linux kernel.

Since Intel Meteor Lake has been the Intel Silicon Security Engine to serve as a silicon root-of-trust for secure firmware loading, boot measurements, and similar functionality. This Intel Silicon Security Engine has been built on with Lunar Lake and Panther Lake as well as set to take on more importance with future Intel hardware platforms. We are now seeing a Linux driver come for this silicon RoT with the Intel Silicon Security Engine Interface (ISSEI).

Following last week's disclosure of the Dirty Frag vulnerability for the Linux kernel, which only finished being patched up in mainline on Monday, Fragnesia is now public as a similar local privilege escalation (LPE) vulnerability.

GCC 16.1 released at the end of April as the latest major, annual feature release to the GNU Compiler Collection. Early benchmarks showed some nice leads for GCC 16 over GCC 15. Continued testing of the new GCC 16 compiler has continued to show overall better performance of the resulting binaries than using GCC 15 on the same hardware and same compiler flags. That led many to wonder about the GCC 16 performance up against the latest LLVM/Clang open-source compiler, which is the focus of today's benchmarking showdown.

It's been nearly one year to the week since Intel introduced Project Battlematrix as their initiative for improving their Linux driver support for the Arc Pro B-Series with enhancements such as bettering the multi-GPU support in allowing up to eight Arc Pro GPUs per system as well as other open-source driver optimizations in the era of AI. Recently with the Arc Pro B70 in having four review samples for testing I was finally able to try out the multi-GPU state of the Arc (Pro) graphics cards on Linux with their open-source driver code.

A new driver expected to land in the upcoming Linux 7.2 kernel is the ARCTIC Fan Controller driver to allow fan speed monitoring and PWM controls for this upcoming ARCTIC product. Making this new driver all the more exciting is that it was worked on by ARCTIC directly compared to the typical workflow for such desktop/consumer hardware peripherals often being left up to the reverse-engineering, open-source community.

Prominent Linux kernel engineer Peter Zijlstra of Intel has been working on a set of scheduler patches to help with enhancing the behavior and delivering better results, especially for aging hardware he described as a "potato" -- an Intel Sandy Bridge desktop CPU with AMD Radeon RX 580 Polaris graphics. Benchmark results are promising from this work for gaming on old hardware while other workloads may ultimately stand to benefit too.

Fresh off the milestone of Dell and Lenovo becoming premier sponsors of the Linux Vendor Firmware Service (LVFS), there is a new feature release of the Fwupd firmware updating tool for Linux systems.

For years Intel has been developing the Low Power Mode Daemon "LPMD" to help their hybrid laptop and desktop CPUs deliver optimal power efficiency under Linux. Intel LPMD leverages hardware hints and other features for optimizing active idle power of the processor and putting the system into lower power modes where possible. This tool could soon call the Linux kernel source tree its new home.

The open-source Haiku operating system inspired by BeOS is now seeing multi-core symmetric multi-processing (SMP) support on ARM64 that works at least in a virtualized world. Plus an assortment of other improvements made to this open-source OS over the course of April.

The open-source Radeon "R300g" driver living within the Mesa codebase for supporting the aging ATI (AMD) Radeon 9500 "R300" through Radeon X1000 "R500" series graphics processors is going through a big code restructuring as part of a big undertaking in 2026...
