With age verification/attestation laws down to the OS level enacted by California and being decided upon by other US states, it's been a hot topic of discussion in the open-source world. For the Debian project that is strictly volunteer/community-driven unlike various commercial Linux platforms, they are figuring out how such laws will impact them.

Ahead of tomorrow's Linux 7.0-rc7 kernel release, this week's batch of input fixes were sent in and merged. Besides a few small input fixes are also some new device IDs and quirks for hardware now to be handled by Linux 7.0.

A small but important patch that looks like it will be merged for the upcoming Linux 7.1 kernel is for enumerating AVX-512 BMM support for KVM virtualized guests. AVX-512 BMM is one of the exciting ISA additions with next-gen AMD Zen 6 processors.

An Amazon/AWS engineer raised the alarms on Friday over the current Linux 7.0 development kernel leading to the throughput for the PostgreSQL database server being around half that of prior kernel versions. The culprit halving the PostgreSQL performance is known but a revert looks like it may not happen and currently suggesting that PostgreSQL may need to be adapted.

Most of my Intel Panther Lake benchmarking over the past two months for the new Core Ultra Series 3 hardware has been done with Ubuntu Linux given the pervasiveness of it, especially in the corporate/enterprise space. But for those looking at achieving even greater out-of-the-box Linux performance on Intel Panther Lake, the Arch Linux based CachyOS does a pretty fine job at further advancing the performance.

Following an April Fools' Day tease of Gentoo claiming they were going to switch to GNU Hurd as their primary kernel moving forward, they have now acknowledged the joke but in fact also announcing there are now experimental Gentoo GNU/Hurd images available.

With Linux 6.19 AMD GCN 1.1 and GCN 1.1 dGPUs now default to the AMDGPU driver rather than the legacy Radeon Linux driver. For these Southern Islands and Sea Islands graphics cards it means much better performance, RADV Vulkan support out-of-the-box, and other improved functionality in using this modern AMDGPU kernel graphics driver on Linux. One of the exceptions has been the GCN 1.1 APUs like Kaveri still defaulting to the older Radeon driver but a patch has been volleyed to make that change.

Meta's great Linux engineering team have been working through some fresh performance optimizations recently from optimizing /proc/interrupts outputs to renewing their investment in jemalloc. A new Linux kernel patch this week provides another optimization to avoid a possible situation of throttling the TCP throughput unnecessarily on Linux systems.

Wayland Protocols 1.48 is out today with the long-awaited XDG Session Management protocol in tow as well as several new experimental protocols.

Last month Dell upstreamed the firmware needed for their XPS 13 935 Snapdragon X1 Elite laptop. This makes the Linux outlook for this ARM-based Dell XPS laptop much better than before in not having to worry about extracting necessary firmware blobs from Windows 11. Now another step forward for the Dell XPS 13 9345 is being made with a new EC driver being posted to enhance the hardware support.

Longtime Linux developer David Woodhouse sent out a patch series today to "deprecate legacy IP" support within the Linux kernel. While some of his commentary his April 1st-esque, he does acknowledge much of this work has merit. Ultimately it can allow for building a Linux kernel with IPv6-only support and working on allowing "legacy" IPv4 support to be disabled as part of the kernel build.

Raspberry Pi prices are going up yet again due to the continued memory squeeze on the industry. To help offset the memory prices for some use-cases, Raspberry Pi also announced the introduction of the Raspberry Pi 4 3GB model at $83 to help fill the void between the 2GB and 4GB options.

Gaim! Any desktop Linux users from 20+ years ago likely remember the Gaim instant messaging app that was commonly shipped by desktop Linux distributions for interfacing with different instant messaging platforms like AIM, MSN, ICQ, etc. About twenty years ago Gaim was renamed to Pidgin though due to the AOL Instant Messenger trademark. But with the AIM trademark since expired and wanting to take a differing approach from the latest Pidgin, Gaim 3 is under development.

AerynOS 2026.03 is now available as the newest release of this from-scratch Linux distribution originally known as Serpent OS. With this month's update comes GNOME 50, KDE Plasma 6.6.3, and various Wayland compositor updates alongside other software improvements.

31 March 06:50 PM EDT - BSD - MidnightBSD 4.0.4

MidnightBSD 4.0.4 is out today as the newest update to this desktop-minded BSD operating system. Notable with this update is introducing the Aged daemon and Agectl program for handling age verification and age attestation given the increasing number of US states pursuing laws around age verification at the OS user level.

A merge request for Wayland Protocols was opened today for introducing "xx-fractional-scale-v2" as an experimental protocol to address current shortcomings with current Wayland fractional scaling. There is also a KDE KWin compositor merge request already out for review that implements this xx-fractional-scale-v2 protocol.

After KDBUS failed to make it into the mainline Linux kernel more than one decade ago as an in-kernel version of D-Bus, BUS1 was proposed as a clean sheet design for in-kernel, capability-based inter-process communication (IPC). BUS1 didn't gain enough traction to make it to the mainline kernel and then many of the same developers devised Dbus-Broker as a more performant D-Bus user-space implementation. Well, as a big surprise now, a new version of BUS1 is being worked on for the Linux kernel.

Sent out yesterday were the DRM Rust feature changes for DRM-Next ahead of the Linux 7.1 merge window coming in April. The Rust graphics/display driver code for Linux 7.1 includes more programming language abstractions and other Rust infrastructure work to make graphics drivers written in Rust more capable.

Servo 0.0.6 is out today to round out the month with many great improvements made in recent weeks to this Rust-based browser engine advancing with its servoshell implementation and many prospects around using it for embedded browser use cases.

Ubuntu 26.04 LTS is just three weeks out for release with many great features in tow from the GNOME 50 desktop to the very leading-edge Linux 7.0 kernel and many other package updates. One feature that many had been looking forward to is Canonical's plans to ship AMD ROCm directly in the Ubuntu archive for a much cleaner experience for those wanting to make use of AMD's open-source GPU compute stack. As a common question in recent weeks from readers, it remains to be seen if that milestone will be achieved for the Ubuntu 26.04 launch day.

31 March 06:07 AM EDT - LVFS - LVFS Sponsors Needed

Last year the Linux Vendor Firmware Service (LVFS) announced plans for major vendors to pay or contribute code to this project that makes it easy for deploying new system and device firmware on Linux systems. They are asking those with less than 99 employees to contribute $10k USD annually or those larger organizations to contribute $100k USD annually or to be employing engineer(s) to work full-time on LVFS/Fwupd. Beginning tomorrow the next phase of their transition to encourage vendors to support the open-source project goes into effect.

In addition to the MediaTek MT7902 WiFI Linux support emerging in recent months, the Linux support for the MediaTek MT7927 is also coming together for WiFi 7 and Bluetooth 5.4 support for the upstream Linux kernel.
