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...

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.

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.
