A patch series that appears destined for the upcoming Linux 7.3 merge window is what's dubbed the "KVM Chainsaw" as a major code clean-up in dealing with the kvm_mmu "god data structure".

Besides the FreeBSD graphics and WiFi drivers lagging behind Linux and other operating systems, the FreeBSD audio driver support and handling of audio streams with FreeBSD on the desktop can be problematic depending upon the hardware/system. One of the most active mailing list threads this week in the FreeBSD camp was over the "tragic state" of FreeBSD audio/sound support.

Auto-CPUFreq is one of the open-source projects striving to be a CPU speed and power optimizer for Linux systems to improve battery life without making any real compromises to the user experience. Out today is v3.1 as the newest feature release of Auto-CPUFreq.

Since 2017 in Linux 4.12 has been the Realtek rtl8723bs WiFi driver where it was introduced into the staging area and remains there nearly a decade later. The rtl8723bs driver for this Realtek 802.11n WiFi SDIO driver has seen a lot of code cleaning over the years and all these years later still is needing lots of code clean-ups from unnecessary code abstractions to dealing with malicious WiFi APs for what Greg Kroah-Hartman has called a "beast of a driver". The latest twist is there now being patches for adding Realtek RTL8723BS and RTL8723B onto the existing RTW88 driver.

Firewire still isn't dead yet on Linux. Current plans call for maintaining IEEE-1394 Firewire on Linux at least through 2029 and with today's Linux 7.2-rc5 kernel release is a fix for those wanting to leverage IPv4 networking over Firewire.

Following last month's beta release, Ubuntu Touch 24.04-2.0 is now available as the latest feature release for this Ubuntu 24.04 LTS derived mobile operating system for select smartphones and tablets.

Posted this week is a draft copy of the Fedora Conflict of Interest policy being worked on for dealing with identifying, disclosing, and managing any actual, actual, or perceived conflicts of interest within the Fedora Project.

Kiwi Menu as the macOS-inspired quick menu option for the GNOME Shell desktop is continuing to enhance its macOS-esque experience on GNOME.

GNU developers today released GNU C Library "glibc" 2.44 as the newest feature release for this critical library to modern Linux systems and other platforms.

KDE developers have been working on kscreenctl as a utility replacement to kscreen-doctor. Plasma and related code has also seen a number of bug/crash fixes coming about this week too.

Wine 11.14 was tagged today as the newest bi-weekly development release of this open-source software for running Windows games and applications on Linux, macOS, and other platforms.

One of many interesting takeaways from this week's AMD Advancing AI event in San Francisco was word that ROCm will be on a rigid six week release cycle moving forward.

Debian developers are discussing a general resolution whether to permit AI large language model (LLM) usage within the Debian software project.

A few days back I wrote about upstream Linux kernel developers marking the Qualcomm crypto accelerator driver as "broken" and "harmful" due to its slow performance, history of bugs, and other limitations. Now this Qualcomm Crypto Engine "QCE" driver might be removed outright from the Linux kernel source tree after discovering it's even worse than anticipated.

Sent out today was the weekly round of drm-misc-next patches of new Direct Rendering Manager feature material ready to be queued in DRM-Next ahead of the Linux 7.3 merge window.

Ubuntu Linux has shipped /etc/debian_version that is carried over from upstream Debian and in turn just indicating the Debian Sid development version from which the packages are arrived. Besides it being inaccurate, /etc/os-release has been the long preferred standard for reading the OS release information. Thus finally Ubuntu developers are looking at dropping the /etc/debian_version file.

Going along with the upstream Linux 7.2 kernel deprecation of AF_ALG and Linux 7.3 to further restrict this interface for letting user-space programs interact directly with the Linux kernel crypto API, Fedora 45 is looking to follow and help support this transition.

At this week's AMD Advancing AI 2026 event, "AI" was mentioned thousands of times in talks and in demos. As expected. Beyond that, the other term likely most heard during the event was "open"... Not particularly new for AMD with their long history of open-source efforts but I'd wager at this year's AMD Advancing AI 2026 event they were more acutely bringing up open-source, open ecosystems, and open standards. Certainly seemed like an uptick in "open" mentions and a ramp that's been building each year at the AMD events.

At the end of last year when checking out the latest Linux experience on the Snapdragon X Elite it was a disappointing affair. The performance had regressed and overall a more headache-inducing experience than just running a modern AMD Ryzen AI or Intel Core Ultra laptop on Linux. Given the recent release of Ubuntu 26.04 LTS, I've been re-testing the Acer Swift 14 AI laptop with Snapdragon X Elite SoC to see how its performing under Linux now and against the AMD/Intel competition. Unfortunately, it's regressed even further than the last round of testing.

After announcing the AMD EPYC 9006 "Venice" processors today at AMD Advancing AI 2026, Lisa Su ended her keynote by confirming EPYC Zen 7 "Florence" details as well as EPYC Zen 8 "Ravenna" being in development.
