With the new Linux 6.5 kernel stable series one of the many new features is defaulting to the AMD P-State driver with the EPP/active mode compared to the long-used default of the ACPI CPUFreq driver. As shown in various Phoronix articles this can help with the mobile/desktop performance with this new default change while this article is looking at the Ryzen for server benefits too.
Amid all the recent chatter around Bcachefs working its way toward mainline and all the ongoing improvements to existing Linux file-systems, you may have forgotten about Puzzlefs as the new file-system aiming to be an optimal solution for containers and with a kernel driver written in the Rust programming language.
Over the summer the AMDGPU compiler back-end in upstream LLVM began with new targets for GFX1150 and GFX1151 which given all things known are likely the "RDNA3 Refresh" APUs. That work started out light with not much in the way of different code paths from the existing GFX11 support but we're beginning to see some new instructions added for the RDNA3 refresh graphics processors.
The CentOS board has approved the creation of a CentOS Integration Special Interest Group (SIG) to assist those building products and services atop Red Hat Enterprise Linux (RHEL) or in particular its upstream, CentOS Stream.

There's just under one month to go now until the X.Org Developers' Conference (XDC) returns to A Coruña, Spain for the annual development conference focused on open-source graphics drivers (Mesa), Wayland, and related Linux display/graphics infrastructure although the X.Org Server itself hasn't received much attention in recent years. Here's a look at some of the planned talks for the exciting XDC 2023.
When it comes to Glibc HWCAPs for allowing the C library to load optimized libraries based upon the CPU features at run-time, it's mostly been focused on the x86_64 world for targeting higher x86-64 levels or being able to load optimized libraries for systems with AVX support. Loongson though has now contributed initial LoongArch HWCAPs support.
While Simultaneous Multi-Threading (SMT) isn't as common on Arm SoCs as it is in the x86 and POWER worlds, there are some SMT-capable designs like with the HiSilicon Kupeng 930 for Arm servers. HiSilicon engineers are working now to extend Linux's SMT run-time controls to work on ARM64 (AArch64).

Released late on Friday was the much anticipated SteamOS 3.5 preview for the Steam Deck with ongoing work around HDR and enhancing color management, VRR for external USB-C displays, various platform issues resolved, auto-mounting external storage, and more. With SteamOS 3.5 it also means some lower-level OS upgrades too like moving to the Linux 6.1 LTS kernel. For those wondering about the performance impact of going from SteamOS 3.4 stable to the SteamOS 3.5 preview release, here are some early benchmarks on the Steam Deck.
Since March of 2022 the ReiserFS file-system has been deprecated and with Linux 6.6 ReiserFS is marked outright as "obsolete" with plans to remove the file-system from the mainline kernel code-base in 2025. In stepping toward that eventual milestone, a new kernel patch series begins removing ReiserFS from the default kernel configurations.
XDG-Desktop-Portal 1.18 is out today as the newest stable release for this leading open-source app sandboxing and distribution tech. Flatpak's XDG-Desktop-Portal 1.18 adds yet more features for this cross-distribution solution for software deployment and package management.
Last November AMD introduced the first of the 4th Gen EPYC series with the EPYC 9004 "Genoa" processors and that was then complemented earlier this year by the July launch of the Genoa-X processors for sporting AMD 3D V-Cache to help technical computing workloads and as well launching Bergamo for the Zen 4C based processor designs that allow up to 128 cores / 256 threads per socket. While AMD has a very robust portfolio for the high-end server space with 4th Gen EPYC, today AMD is introducing the EPYC 8004 "Siena" processors for "intelligent edge" servers. Siena is a step below Genoa but still very capable offering and coming in at a lower price point while being geared more for maximizing power efficiency and opening up EPYC to more deployments outside of the data center.
Stemming from Intel engineers finding significant overhead in some Linux scheduler functions when running PostgreSQL within a Docker instance, a new scheduler patch is on the way for Linux 6.7 that will help out at least Ice Lake and Sapphire Rapids with some migration-heavy workloads. With the change being in the common scheduler code, it's also likely to help out other hardware platforms too.
Since 2021 the Itanium IA-64 code was orphaned in the Linux kernel and over the course of this year there's been talk of retiring the Itanium code from the kernel, a.k.a. strip it out. It looks like 2023 will end with the Itanium IA-64 code indeed being removed from the Linux kernel.
Given the recent discussions stemming from Fedora 40 planning to ship KDE Plasma 6 and drop the KDE Plasma X11 session to focus solely on Wayland for the next-gen KDE desktop, prominent KDE developer Nate Graham has written a lengthy blog post to outline the current state and his thoughts on KDE Wayland support.
