Hopefully being mainlined next cycle with Linux 6.1 is the Multi-Gen LRU, or better known as MGLRU, as a superior alternative to the kernel's existing page reclamation code. Assuming it lands for Linux 6.1 as the last complete kernel cycle of 2022, this would make it one of the most exciting innovations to make it into the kernel this year...

Held today during the first day of Linux Plumbers Conference 2022 in Dublin was a Rust mini-conference about the ongoing work on making Rust a suitable systems programming language and integrating support for Rust within the mainline Linux kernel. There were many interesting talks from the status of the Rust integration from the Linux kernel to a Rust-written NVMe driver that can perform as well as the C written driver...

Google for quite some time now has been working on "Ghost" as a means of controlling the Linux kernel scheduler from user-space and/or eBPF programs. Ghost provides an extensive API so developers can alter the kernel's scheduler behavior from user-space or eBPF and fine-tune the scheduling behavior based on system preferences...

Since NTFS3 was mainlined last year in the Linux kernel as a modern NTFS read/write file-system driver developed by Paragon Software, it's mostly just been some fixes since then and other minor updates. A new NTFS3 patch series sent out today is at least preparing a new feature for this kernel driver...

One of many changes to find with next month's Ubuntu 22.10 release is Debuginfod integration...

Now that Ubuntu 22.10 is into its feature freeze and its Linux 5.19 based kernel landed as well as moving to the GCC 12.2 compiler, I've begun testing this forthcoming Ubuntu Linux (non-LTS) release on more systems. For the current-flagship Intel Xeon Platinum 8380 "Ice Lake" processors, Ubuntu 22.10 does deliver some performance advantages over the current Ubuntu 22.04.1 LTS release. However, Ubuntu 22.10 still trails in a distance behind Intel's own Clear Linux platform for the most aggressive out-of-the-box performance.

The PyTorch Foundation has been formed under the Linux Foundation umbrella by Meta (Facebook), AMD, AWS, Google Cloud, Meta, Microsoft, and NVIDIA to focus on providing the leading-edge AI framework...

Added to the mainline Linux kernel last year was a Aquacomputer HWMON driver for initially supporting the German company's water-cooling pump under Linux with access to the fan speed, power, voltage, current, and coolant temperature. Since then that open-source driver developed by the community has been extended to cover an Aquacomputer fan controller and different models. For the Linux 6.1 cycle coming up there are more additions to the Aquacomputer driver...

Last week Laminar Research promoted X-Plane 12 to its early access public beta phase. This realistic flight simulator continues to natively support Linux -- and doing so well for many years -- and now with X-Plane 12, the Vulkan steps up past their long-used OpenGL renderer...

The Linux Plumbers Conference has returned to being an in-person event and is running today through Wednesday in Dublin, Ireland...

Disclosed back in March was the Spectre-BHB / Branch History Injection (BHI) speculative execution vulnerability that on the Arm side affected CPUs from the likes of the Cortex-A15 through A78 series as well as the likes of the X1, X2, and A710, plus the Neoverse E1 / N1 / N2 / V1 CPUs. Now for Linux 6.1, a command-line option is being added for ARM64 to be able to disable the Spectre-BHB mitigation due to the "great impact" to performance...

As part of the multi-year effort to overhaul the Linux kernel's printk() code there has been much work in recent months around threaded console printing so each registered console would have a kernel thread and console printing would be decoupled from the printk() callers. That work was aimed for Linux 5.19 but then reverted due to troubles. There is now a new implementation in the works...

Canonical used to host a stellar in-person event each Ubuntu Linux development cycle with the Ubuntu Developer Summit. That was over a decade ago and then it became largely a virtual event and then faded away in favor of Canonical's internal road-map planning and other developer sprints among their employees. Coming up in November in Prague is the return of an in-person official event with the Ubuntu Summit...

AMD engineers are working to better optimize the Linux kernel's scheduler for split-LLC (last level cache) processor designs, namely to benefit their EPYC server processors...

Sent out as a "request for comments" on Friday night was a new patch series out of Intel introducing the notion of "classes of tasks" for the Linux kernel so that the scheduler can make better decisions on hybrid processors like with Intel's Alder Lake processors and upcoming Raptor Lake. This also provides a more complete implementation of Intel Thread Director for Linux and may also be used as the basis for instruction set differences between the performance and efficient cores...

Intel engineers have submitted another batch of "i915" kernel graphics driver changes intended for Linux 6.1 that include updated GuC firmware version handling, more DG2/Alchemist Arc Graphics work, and also more Meteor Lake "MTL" enablement for that successor to Raptor Lake...

Fedora Linux releases whether they be development/beta snapshots or the stable releases are known for slipping all too often. Fedora will often delay due to blocker bugs as they aim to deliver a bleeding-edge yet reliable Linux distribution and thus a week or two delay here and there isn't uncommon at all. While they have been delivering more timely releases than in the past with their notorious delays, for Fedora Linux 37 Beta they have delivered on the feat of an on-time release...

KDE Plasma 5.26 is due for release on 11 October while the Plasma 5.26 beta is planned for next week. As such the developers involved have been quite busy with finishing touches ahead of the beta...

For the past two decades Red Hat has been behind Sourceware.org for providing hosting for open-source projects like Cygwin, GNU GCC, GDB, Glibc, and many other projects. While Red Hat continues to sponsor the hosting and having their employees be involved with the Sourceware.org maintenance, etc, for ensuring a secured future they have been looking to hookup with the Software Freedom Conservancy (SFC). The SFC has now voted in favor of accepting this long-time open-source hosting service into their umbrella...
