Linux 7.0-rc6 was just released in quickly working toward the stable Linux 7.0 release in mid-April. This was another busy week with lots of bug fixes...

Here's something that wasn't on my bingo card for this year of the "MKISS" driver for ham radio being modernized in 2026 as opposed to just being dropped. The MKISS code hasn't seen much driver activity since the original Git import of the Linux kernel more than twenty years ago...

Last year Intel began preparing their QuickAsist Linux driver support for QAT Gen6 hardware with upcoming platforms. That initial Intel QAT Gen6 driver enablement landed back in Linux 6.16 while for the upcoming Linux 7.1 kernel they are preparing support for a new wireless mode with this next-gen QuickAssist hardware...

Sent out this week was another drm-misc-next pull heading to DRM-Next ahead of next month's Linux 7.1 merge window. Notable with this week's Direct Rendering Manager code changes was introducing per-process buffer object "BO" memory usage query support for user-space...

Released this week was Nginx 1.29.7 as the newest mainline version of this HTTP(S) web server. Releasing alongside Nginx 1.28.3 stable, it fixed buffer overflow vulnerabilities and some other vulnerabilities. Making Nginx 1.29.7 more exciting though is that it landed Multipath TCP support...

It's fairly rare for the RadeonSI Gallium3D driver to hit OpenGL rendering game bugs these days as besides more games going opting for Vulkan API use, RadeonSI is rather robust and very mature at this stage. Recently though a Linux gamer that upgraded to a Radeon RX 9070 XT RDNA4 graphics card noticed that the open-source EDuke32 Duke Nukem 3D build and its derivatives were failing to render properly with the RadeonSI driver...

It was just two weeks ago that GIMP 3.2 released, one year after the big GIMP 3.0 debut. Out today is GIMP 3.2.2 with various bug fixes, plug-in / file format handling updates, and some minor UI/UX work...

AMD's GAIA AI agent framework (that previously stood for "Generative AI Is Awesome" albeit they seemed to have dropped promoting it as that name) for Ryzen AI hardware is out with a new version. AMD GAIA 0.17 introduces Agent UI as a new privacy-first web application for local AI agents...

It's a big undertaking but they have begun staging patches for review and testing to get this massive set of changes up to par for mainline...

Framework Computer as the company behind the modular Framework laptops and incredible Ryzen AI Max "Strix Halo" Framework Desktop has stepped up their support for the KDE community...

Earlier this week I provided benchmarks looking at KDE Plasma 6.6's performance advantage over GNOME 50 for Linux gaming with AMD Radeon graphics. That raised the question if the same was true when using NVIDIA graphics with their official Linux graphics driver stack. Here are such benchmarks looking at the KDE Plasma 6.6 and GNOME 50 performance on Ubuntu 26.04 beta while using the new NVIDIA 595.58.03 Linux driver.

Following the Intel Xe kernel graphics driver pull request landing transparent hugepages for device pages as an SVM win, another round of Intel Xe driver updates were sent out this week ahead of next month's Linux 7.1 merge window. This latest pull request lands a new user-space API for helping the Intel Xe driver better cope with situations of video memory pressure / out-of-memory behavior for vRAM...

With sched_ext there is support for BPF-based CPU scheduling policies for the Linux kernel while now a new initiative is working on BPF-based I/O schedulers...

An important set of Linux scheduler patches were posted for review on Thursday for improving the SMT-aware asymmetric CPU capacity handling. These patches to improve the Linux kernel scheduler around CPU Simultaneous Multi-Threading (SMT) is needed after NVIDIA engineers discovered up to a ~2x performance drop for CPU-intensive workloads on their upcoming Vera Rubin platform...

Another round of AMDGPU/AMDKFD kernel driver improvements were sent out this week as feature development for DRM-Next ahead of Linux 7.1 begins to wind down...

Released today was wlroots 0.20 as this Wayland support library used by some Wayland compositors for doing much of the "heavy lifting" of compositor bring-up. Following wlroots 0.20, Sway 1.12-rc1 was released for testing as this closely-aligned Wayland compositor inspired by the i3 window manager...

Right on schedule the beta for Ubuntu 26.04 LTS is now available for testing. This is a great opportunity to help test this release ahead of the official Long Term Support release due out on 23 April...

Merged today was the very first step toward implementing Vulkan support within KDE's KWin compositor as an alternative to OpenGL rendering...

As a few months have passed since our prior round of testing the fully open-source NVIDIA Linux driver stack with the Nouveau kernel driver and Mesa NVK Vulkan driver plus Zink, here is a fresh round of benchmarks using Linux 7.0 and Mesa 26.1-dev compared to the open-source stack shipped by Ubuntu 25.10 (Linux 6.17 + Mesa 25.2) for showing how far the open-source NVIDIA driver has progressed the past few months. Plus testing against the NVIDIA official Linux graphics driver for putting that Nouveau/NVK performance into perspective.

Standing out in this pull is enabling Transparent Hugepages (THP) support for drm_pagemap as a big win for those making use of Shared Virtual Memory (SVM) for GPU compute and the like...

One of the early features for Fedora 45 that was approved this week is enabling IPv6-mostly support within NetworkManager for a more modern out-of-the-box network experience...

Last month NXP posted open-source Linux kernel driver patches for their Neutron NPU accelerator. The NXP Neutron NPU aims to help with edge AI applications and this neural processing unit is found in their different SoCs. Unfortunately, their GitHub repository for the user-space software ends up containing a binary-only blob that will end up delaying plans on getting this driver into the mainline Linux kernel...

A new set of Linux kernel patches for batch TLB flushing for dirty folios within the kernel's vmscan path were recently floated on the Linux kernel mailing list. This batch TLB flushing optimization for dirty folios during memory reclaim can be a significant performance win with today's multi-core hardware...

Merged today was another round of platform-drivers-x86 changes for the ongoing Linux 7.0 cycle. There are bug fixes plus some new hardware support additions that make this merge notable. Due to the new hardware support amounting to just device IDs and not risking existing hardware support, it's fine for merging at this late stage of Linux 7.0 development...

With just a few weeks to go until the official Fedora 44 release, there is already feature planning and activity beginning for Fedora 45 that will be released toward the end of 2026. Among the early feature approvals is a new web front-end feature to the DRM Panic "Blue/Black Screen of Death" functionality with a specialized QR code for kernel errors...

In testing thus far on Ubuntu 26.04, the KDE Plasma 6.6 desktop with the Wayland session is working pretty darn well and delivering a performance edge across many games/graphics workloads compared to the default GNOME 50 desktop. At least as far as AMD Radeon graphics are concerned, Plasma 6.6 is in quite impressive shape for the upcoming Ubuntu 26.04 LTS release.

Alongside announcing the new Intel Core Ultra Series 3 Panther Lake parts with vPro for commercial PCs and the Xeon 600 workstation processors, Intel finally announced their professional "big Battlemage" BMG-G31 graphics card with the Arc Pro B70 as well as the Arc Pro B65...

Earlier this month with the release of the Lemonade SDK 10.0 and FastFlowLM 0.9.35, using AMD Ryzen AI NPUs for running LLMs on Linux finally became feasible. AMD XDNA 2 NPUs can now run on Linux well for LLM workloads! Released on Tuesday was Lemonade 10.0.1 with a few improvements for the setup process of this local LLM open-source solution on Linux...

Ubuntu developers at Canonical are looking to strip the signed GRUB bootloader features to the bare minimum for the Ubuntu 26.10 release later this year. Dropping support for XFS, ZFS, Btrfs, LVM, md-raid (except RAID1), LUKS-encrypted disks, and other features is being looked at in the name of security...

With the recent Fedora 44 beta release, Mesa 25.3 graphics drivers were in use rather than the newest Mesa 26.0 series. The good news is that there is now approval for getting Mesa 26.0 drivers to land in time for next month's official Fedora 44 release...

Unvanquished 0.56 is out today as the latest major update to this prominent open-source, community-driven shooter game.
