Intel Lunar Lake On Linux Can Roughly Match Windows 11 Xe2 Graphics - When Not Stuck At 400MHz

Earlier this month I looked at the AMD RDNA 3.5 graphics with Strix Point between Windows 11 and Ubuntu 25.04 Linux. The testing showed the AMD RDNA 3.5 graphics on the open-source Linux driver up to around 96% the performance of Radeon Software on Windows. The most frequent question that came up from that most recent round of benchmarking was wondering how the Intel Xe2 graphics on Core Ultra Series 2 "Lunar Lake" now compares between Windows 11 and Linux given that both drivers have been maturing the past several months. Here's the story of the Xe2 graphics between Windows 11 and Ubuntu 25.04 while using a Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition laptop.

Kexec HandOver "KHO" Looks Like It Might Be Ready For The Linux 6.16 Kernel

Being worked on for a while now by engineers from Amazon, Microsoft, and Google has been Kexec HandOver "KHO" as a means of allowing some kernel state to be retained when Kexec'ing into a new kernel such as for maintenance/security updates. The KHO patches in recent days were queued up into Andrew Morton's "MM" staging area leading to hope that this work is ready for mainlining with the Linux 6.16 kernel cycle this summer...

AMD RDNA4 Paired Context Reg Feature Merged For RADV To Potentially Help Performance

After various commits to Mesa 25.1 in recent days in preparing for a new paired context registers feature of AMD RDNA4 (GFX12 graphics), the feature today is wired up for the Radeon Vulkan driver "RADV" with the upcoming Mesa 25.1 release. This feature has the possibility of helping performance for new AMD RDNA4 hardware but the performance benefits at this time aren't clear...

Amarok 3.3 Beta Released For Qt6-Powered KDE Music Player

Last year work on KDE's Amarok music player was resurrected after a six year development hiatus. With the return to Amarok development it was ported to Qt6 and KDE Frameworks 5. At the end of last year Amarok 3.2 released with initial Qt6 and KDE Frameworks 6 support while retaining Qt5/KF5 support. Now out today is the Amarok 3.3 beta to drop that prior-generation support...

Intel TDX Support For KVM Finally Expected To Debut In Mainline Linux 6.16

While the Linux 6.15 merge window ended just one week ago and there is a month and a half until it will debut as stable, a notable feature has already been queued into a "next" branch for the follow-on Linux 6.16 cycle. For those making use of modern Intel Xeon processors with virtualization, the Trust Domain Extensions (TDX) support for KVM virtualization looks like it will finally be mainlined...

Pinta 3.0 Image Editing Program Released With Port To GTK4

One month after GIMP 3.0 was finally released for this popular image editor ported to GTK3 and many other changes, Pinta 3.0 has now been released. Pinta as a reminder is the open-source image editing program inspired by Paint.NET. With the Pinta 3.0 release the image editor has been ported to GTK4 and libadwaita...

Qualcomm USB Audio Offloading Poised For Linux 6.16 After Going Through 38 Revisions

Originally posted back in 2022 were Linux kernel patches for Qualcomm USB audio offloading for Qualcomm SoCs with an audio DSP that can take responsibility for issuing transfers to the USB host controller to free up system resources. After going through 38 rounds of code review the past 2+ years, it looks like Linux 6.16 will finally mainline this Qualcomm USB audio offloading support...

IBM z17 Open-Source Compiler Support Now Being Officially Recognized

Earlier this week IBM announced the z17 mainframes powered by Tellum I processors. But months prior we've seen IBM patches for an "arch15" target for SystemZ within the open-source compilers that we expected was z17. IBM has now confirmed such and has begun updating the open-source compilers to acknowledge this z17 compiler support...

Mesa 25.1 Merges Support For Intel EU Stall Sampling As New Xe2 Profiling Feature

Merged to the Intel Xe kernel graphics driver for the current Linux 6.15 kernel cycle is EU Stall Sampling support as a new feature found with Xe2 Lunar Lake and Battlemage graphics. EU Stall Sampling is used for exposing information/reasons why execution units are stalled for helping to debug performance issues. Now that the kernel support is ready to go with Linux 6.15, merged to the Mesa 25.1 development code is the user-space support for this performance debugging feature...

Linux Tightening Up AMD Zen 5 CPU Microcode Check

Google engineers earlier this year detailed an AMD CPU microcode signature verification vulnerability. For local users with administration/root privileges, it could lead to loading malicious CPU microcode patches on the system. Initially AMD Zen 1 through Zen 4 were affected but the Google security engineers since discovered Zen 5 also could be impacted. BIOS updates are rolling out to address this signature verification issue while the Linux kernel is also being patched for microcode protections on Zen 5...

Intel Linux Graphics Driver Will Now Be Less Restrictive Over RAM Use

A change merged yesterday to the Intel Mesa graphics driver code lessens a restriction around the amount of system memory (RAM) that can be used by processes for the Vulkan system heap. This will allow more games/apps to work with the Intel integrated graphics that previously exceeded the driver-enforced limits but at the risk of running into broader out-of-memory behavior if under too much memory pressure...
