OpenZFS 2.3-rc1 released last week with RAIDZ expansion, fast deduplication, and direct IO support among other changes for this ZFS file-system implementation for use on Linux and FreeBSD systems. OpenZFS 2.3-rc2 is out today with a few more interesting changes.
In addition to NVIDIA engineers being at XDC 2024 in Montreal last week for talking about their Wayland driver plans, there was also a presentation by NVIDIA's Daniel Dadap around current Linux challenges in supporting dynamic display mux hardware on modern laptops with iGPU/dGPU combinations and their hopes for improving the support.
With the newly-launched AMD EPYC 9005 series processors continuing to use Socket SP5, there is drop-in upgrade compatibility for existing EPYC 9004 series motherboards/servers. That's assuming, of course, the vendor provides a BIOS update for enabling the EPYC 9005 series "Turin" support and there may be limitations on the maximum CPU/TDP supported given power/thermal constraints. But in going from EPYC 9004 to EPYC 9005 is also upping the maximum memory speed from DDR5-4800 to DDR5-6000 (or DDR5-6400 in validated configurations). For those trying to weigh the benefits of also upgrading your memory if on an existing EPYC 9004 Genoa/Bergamo server to DDR5-6000, here are some memory performance comparison benchmarks for some reference points.

Linux 6.12-rc3 is out today as expected as the newest weekly release candidate in working Linux 6.12 toward a stable release in November.
With a number of patches queued this week into the staging tree ahead of the Linux 6.13 kernel, a number of old and no longer maintained hardware drivers are set to be removed in the next kernel cycle.
As a result of user feedback and being able to reproduce some annoying ad experiences, particularly on mobile devices, I've been able to make some enhancements to hopefully improve the user ad experience when browsing Phoronix.
Building off the recent infrastructure merged for Mesa 24.3 as a build option to allow Rusticl driver support to be enabled by default, Red Hat's Karol Herbst has added the Asahi Gallium3D driver to the default list.
Adding to the growing set of features for NVK as this open-source NVIDIA Vulkan driver within Mesa, the VK_KHR_fragment_shading_rate fragment shading rate extension is now supported.
While Azure Linux 3.0 has been available since the late summer, for those continuing to rely on Azure Linux 2.0 in production there is a big update out this weekend. Azure Linux 2.0.20241006 brings dozens of security fixes to this Microsoft Linux distribution.

Wayland Protocols 1.38 is out with three new staging protocols.
Back in January AMD published an open-source XDNA Linux kernel driver for supporting their Ryzen AI NPUs. But it wasn't until July that the formal review process for the AMD XDNA driver began as the necessary prerequisite for getting picked up into the mainline Linux kernel. On Friday the fourth iteration of those patches for review were published as it hopefully is closing in on landing within the mainline kernel.
The Haiku open-source operating system project inspired by BeOS is out with their newest monthly development summary to highlight advancements made to this unique OS.
With Intel Core Ultra Lunar Lake systems now shipping and the Linux support largely settled, Intel open-source software engineers have begun ramping up their support for Panther Lake due out in a year.
A Friday evening job posting has confirmed and reinforced details around their future AI GPU compute stack, presumably what's been referred to as the Unified AI Software Stack.
Following this week's release of KDE Plasma 6.2, the KDE developers are busy addressing some of the initial fallout from this desktop update as well as more feature work aimed at Plasma 6.3.

As another interesting AMD announcement this week following their Advancing AI event yesterday where they launched the EPYC 9005 series and other new hardware, they've continued with a few more soft announcements in the lead-up to the OCP Global Summit happening next week. The latest interesting tid-bit is their plans to incorporate Project Caliptra into their products beginning in 2026.
The IO_uring asynchronous I/O API for Linux is quite novel and has proven performance benefits. With time IO_uring has been adapted to other areas of the kernel like networking and now with a proposal raised by an Arm graphics driver engineer, it could potentially be adapted for use by Direct Rendering Manager (DRM) kernel graphics drivers.
Now past the launch day for the AMD EPYC 9005 series server processors and having delivered initial AMD EPYC Zen 5 benchmarks for the EPYC 9575F / EPYC 9755 / EPYC 9965 SKUs, it's onto one of my favorite areas of testing and that is the more focused benchmarks looking at different specific changes/features of new processors. Today under the benchmarking microscope is looking at the new AVX-512 512-bit data path capabilities of 5th Gen AMD EPYC compared to using a 256-bit data path or disabling AVX-512 entirely.
The drm-xe-next pull request earlier this week began preparing open-source driver support for Intel Xe3 graphics to premiere with Panther Lake processors. That code is beginning to queue for the upcoming Linux 6.13 cycle. Today a drm-intel-next pull request was sent out to prepare for more Intel Linux kernel graphics driver changes for Linux 6.13.
