Hitting the mailing list today are patches providing initial support for AMD's next-gen NPU "AIE4" platform, complete with SR-IOV support.

While having the new System76 Thelio Mira in the lab I ran some benchmarks of Ubuntu 24.04 LTS vs. 26.04 development on that AMD Ryzen 9000 series powered desktop. Those results were interesting for how the Ubuntu performance has changed over the past two years, but even if drilling down to just the past six months there have been some nice gains on the AMD Zen 5 desktop. In this article is a look at how Ubuntu 26.04 in its near-final state is performing relative to Ubuntu 25.10 with this Ryzen 9 9950X desktop.

Coreboot 26.03 was christened today as the newest quarterly feature release for this open-source system firmware implementation that strives to replace proprietary BIOS/firmware. Most notable with Coreboot 26.03 is full support for Intel Core Ultra Series 3 Panther Lake SoCs.

The open-source RadeonSI Gallium3D driver with Rusticl for modern Rust-based OpenCL is nearing formal OpenCL 3.0 conformance with all necessary OpenCL test cases passing. Making this all the more interesting is that this is the first modern AMD graphics hardware in a decade likely to see formal recognition for OpenCL conformance with AMD having not submitted any of their own OpenCL conformance results since 2015.

Last week I ran benchmarks quantify the performance benefit to Intel FRED for Flexible Return and Event Delivery initially found with the new Core Ultra Series 3 "Panther Lake" processors and also for upcoming Nova Lake and Diamond Rapids CPUs. The FRED performance impact was very beneficial across a variety of workloads but rather strangely was not enabled by default. Mere hours after publishing that article, an Intel engineer posted a patch to enable FRED by default. Now this week that patch appears all-set for merging with the upcoming Linux 7.1 merge window.

A proposal was submitted today for launching the RISC-V Compiler Collaboration "RVCC" as an LLVM Incubator project to focus on compiler optimizations for better performance on RISC-V. But before getting too excited, there is already some opposition to the proposal.

After starting and leading the Ubuntu MATE flavor since 2014, Martin Wimpress announced he's looking to step down from leading this flavor of Ubuntu Linux with the MATE desktop environment. He's hoping for new passionate contributors to keep it going.

Rspamd 4.0 is out today as a big update to this powerful open-source spam filtering system.

The Mesa Radeon "RADV" Vulkan driver has added new low-latency Vulkan Video encode/decode options for those seeking better performance.

Sent out today was the latest batch of drm-intel-next changes as feature work toward DRM-Next for Linux 7.1 winds down. This week's drm-intel-next pull is mostly fixes and some low-level code refactoring. The only item really standing out is some new quirk infrastructure for dealing with laptop display panels that may have buggy Panel Replay handling.

Back in 2023 AMD posted hardware-accelerated virtualized IOMMU patches for the Linux kernel as a request for comments (RFC). In 2024 they then posted a second iteration of the AMD vIOMMU patches but then seemingly fell off the radar. This morning is now the first set of updated AMD vIOMMU patches sent out on the Linux kernel mailing list with the RFC tag now removed.

SolveSpace 3.2 was released this past week as the newest feature update to this open-source parametric 3D CAD tool for creating 2D/3D parts and other CAD diagrams.

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.

Ahead of the Linux 7.0-rc6 kernel due to be released later today, quite a number of EXT4 file-system fixes were sent out this morning.

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.
