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...

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...

In working toward the stable Plasma 6.7 desktop release in mid-June, out today is the first beta of KDE Plasma 6.7...

Sent out on Wednesday was the latest AMDGPU/AMDKFD driver pull request of new feature code ready for DRM-Next as the staging area ahead of the upcoming Linux 7.2 kernel. This doesn't yet land the HDMI 2.1 enablement work that's finally been taking place but it is preparing for that with the FRL register headers now in place as part of this merge...

Introduced to the Linux kernel last year was Control-flow Enforcement Technology "CET" virtualization for modern AMD and Intel CPUs. This complements CET that has existed in Linux for quite some time but it's new now to the KVM virtualization world, but some yet to be diagnosed problems are causing some hosts to hang when making use of this virtualization security feature...

Timur Kristóf of Valve's Linux open-source graphics driver team isn't done driving new improvements to aging AMD GCN 1.0/1.1 era graphics cards on Linux. Beyond enhancing display support for older APUs, transitioning GCN 1.0/1 GPUs from the legacy Radeon driver to modern AMDGPU driver, and a host of other fixes and optimizations for these old GPUs going back to the Radeon HD 7000 series, he has another notable addition that was announced today. These original GCN graphics cards with pending patches to the AMDGPU kernel driver and Mesa user-space can now allow for DRM format modifiers...

The PanVK Vulkan driver and Panfrost Gallium3D driver for Arm Mali graphics hardware is now supporting the latest "v14" hardware GPU hardware with the Arm Mali G1-Pro now being advertised as supported...

Minule jsme spustili základní infrastrukturu pro běh našich služeb. Nyní se podíváme na dva nástroje, které nám společně zajistí bezpečné zálohování. Kopia pořídí snímek dat a Rclone vše přesune do úložiště.

Popíšeme si VBI, tedy Vertical Blank Interrupt. Jde o subrutiny volané po dokončení vykreslování snímku, či na začátku vykreslování dalšího snímku. Mnohé hry mají své jádro (kernel) implementované právě přímo ve VBI.

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.

Intel on Tuesday released a new version of their open-source Compute Runtime for OpenCL and Level Zero support across their integrated and discrete graphics hardware...

Discord, the popular instant messaging and VoIP communication platform, announced some significant improvements being made to their Linux client...

In addition to FreeBSD 15.1 releasing in the coming weeks, NetBSD 11.0 is also just around the corner as another prominent and major BSD update. NetBSD 11.0-RC4 is now available for last minute testing with this hoping to be the final release candidate...

KDE today announced a significant investment into the project by Germany's Sovereign Tech Fund. KDE will be receiving €1,285,200 EUR (or roughly 1.5 million USD) over the years 2026 and 2027 to make some significant improvements into their software stack...

A new core infrastructure improvement for the Linux kernel on ARM being worked on is enabling 128-bit page table entries (PTEs) with FEAT_D128 as a new optional feature of Armv9.3 and later...
