There was an exciting mix of software and hardware happenings over the past month. Here is a look back at what excited readers the most.

In mid-October a Meta engineer uncovered an RDSEED architectural issue with AMD Zen 5 CPUs. A patch in turn was sent out to the Linux kernel mailing list to disable RDSEED usage on affected Zen 5 processors. AMD this week issued a security bulletin to acknowledge the issue and report that a microcode fix is coming.

Over the summer months LunarG announced KosmicKrisp as a new Vulkan-on-Metal implementation for Apple devices and built around Mesa. That alternative to MoltenVK was upstreamed for next quarter's Mesa 26.0 release and now it's also celebrating being an officially Vulkan 1.3 conformant implementation.

Yesterday Canonical announced architecture variants for Ubuntu Linux with Ubuntu 25.10 seeing the introduction of "amd64v3" packages that are built for the x86_64-v3 micro-architecture feature level to assume AVX/AVX2 and other newer CPU ISA features found since Intel Haswell and AMD Excavator processors. Eager to run some initial tests, here is a first look at the Ubuntu 25.10 amd64v3 performance for desktop workloads.

Over the past day there have been many reports of AMD planning to no longer provide game optimizations for the Radeon RX 5000 and RX 6000 series graphics cards for their Microsoft Windows driver. Surprisingly many in the Linux community still seem to think it will impact the Linux drivers, but long story short, there is no real concern for Linux users/gamers.

This week marks fifteen months since AMD Strix Point laptops began shipping. Back at the end of July 2024 the Linux performance and support was already in good shape while since then the Linux performance has only evolved even more to make these AMD Zen 5 laptops perform even better. Here is a fresh look at how the performance has evolved since launch day and the added gains when moving to the recently released Ubuntu 25.10 and some performance advantages too if moving to the in-development Linux 6.18 kernel.

The Linux Vendor Firmware Service (LVFS) that goes hand-in-hand with the Fwupd open-source firmware updating utility celebrated the milestone on Wednesday of crossing 135 million firmware updates.
