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...

From my early testing thus far of the Linux 6.6 kernel in its very early state, some of the most impressive gains are happening on AMD's high core count server processors, the EPYC 9754 "Bergamo" in particular is enjoying some stellar improvements for various server workloads on this forthcoming kernel.

The Linux kernel currently allows disabling support for 32-bit programs and 32-bit system calls at compile-time, but a new option expected to be introduced with Linux 6.7 this winter will provide a new "ia32_emulation" boot time option to allow unconditionally disabling support for 32-bit programs and system calls...

The past two years AMD's AMDGPU Linux kernel driver has supported Seamless Boot on Van Gogh APUs notably used by Valve's Steam Deck. AMD Seamless Boot is for a seamless or flicker-free boot experience by aiming to avoid redundant/unnecessary mode-sets by the driver. After a few years being limited in its scope of supported hardware, new patches are aiming to open up Seamless Boot usage to more AMD Radeon graphics hardware...

One of the nifty new features with Intel Xeon Scalable "Sapphire Rapids" processors not talked about much is the In-Field Scan (IFS) functionality for allowing various tests to be carried out prior to deploy the new processors or over time in the data center for trying to spot any silicon-level issues. IFS aims to uncover any processor issues not caught by ECC, parity checks, RAS, or other safeguards when new CPUs reach the data center or as they age over time...

During the Linux 6.6 merge window a pull request submitted the new "GenPD" subsystem. While the pull request did land for Linux 6.6, Linus Torvalds took issue with it -- not because of the code but over the lack of clarity on what "GenPD" is for those not domain experts in this area. To help clear things up, GenPD is being renamed to "pmdomain" to provide a bit more clarity...
