The long time Phoronix reader, with an excellent long-term memory, may remember an odd article from back in August 2017 on buying a passively cooled computer. It tells the tale of the consumer who decided to buy a rather niche, fanless, therefore passively cooled computer.
Way back in August Intel posted a set of Linux kernel patches for supporting "unaccepted memory" by the Linux kernel in preparation for next-generation Xeon processors and speeding up the boot time for guest virtual machines making use of Intel's Trust Domain Extensions (TDX) security feature. Unaccepted memory support hasn't yet made it to the mainline kernel but now a second iteration of the patches have been posted.
Over the years the Linux kernel has picked up many different sanitizers, memory leak detectors, and other features for helping to diagnose and address deficiencies in the kernel. However, all of these debugging-optimized features aren't centrally located that can make it difficult for system administrators and developers to spot these numerous features when configuring a kernel build manually. Now with Linux 5.17 that is changing.
Last week I noted about EDAC changes in Linux 5.17 for future AMD CPUs. The "Error Detection and Correction" work included AMD adding RDDR5 / LRDDR5 support to their driver and new CPU model IDs that appear to be for Zen 4. Also working on next-gen AMD processor support in Linux 5.17 are recent SMCA changes.
I've been writing about Genode OS for over a decade as one of the interesting original, open-source operating system frameworks that has taken novel approaches to many design elements and continues persevering with their efforts. For 2022 the project has yet more ambitious goals ahead.
F2FS as the Flash-Friendly File-System may not see too much use out of desktop Linux distributions at least as it concerns any easy/semi-endorsed root install option, but this file-system does continue maturing and seeing much use by enthusiasts and especially among the plethora of Android devices now supporting this flash-optimized file-system. With Linux 5.17, F2FS has some performance improvements and other fixes.

The Linux Vendor Firmware Service (LVFS) that integrates with Fwupd for delivering firmware updates primarily to Linux users is surging with around three times the normal traffic volume. Unfortunately, this boost in traffic appears to be due to vendor(s) releasing new system firmware updates ahead of disclosing a presumptive security issue.
The Qt Company this morning announced Qt Digital Advertising 1.0 as its new ad platform that allows for developers to easily integrate advertising campaigns into Qt-based, cross-platform applications.
At the end of last year AMD introduced OpenGL sparse texture support into its RadeonSI Gallium3D driver. This functionality for Vega GPUs and newer flipped on ARB_sparse_texture support while now with the very latest Mesa 22.0-devel code ARB_sparse_texture2 is now flipped on too.
NVIDIA has released CUDA 11.6 as the latest version of their widely used but proprietary GPU compute stack. With CUDA 11.6 there are some good improvements and new features in store.

The alpha release of GNOME 42 is now available for testing.
GCC 12 as this year's annual GNU Compiler Collection feature release has moved on to "stage four" development with likely releasing GCC 12.1 in April.
Last September I was the first to call attention to Intel working on a new feature to allow updating some system firmware components without needing to reboot such as for mission critical servers that try to avoid downtime at all costs. That Intel "Seamless Update" feature also known as Platform Firmware Runtime Update and Telemetry (PFRUT) has now been sent in for mainlining with Linux 5.17.

For those considering the Lenovo USB-C 7-in-1 Hub for connecting to your Lenovo laptop for enjoying USB-C power charging, HDMI output, and additional USB ports, it does work out on Linux. While there have been some users running into seemingly firmware-related issues, at least with my testing over the past month this $50~60 (USD) USB-C hub has been working out well under Linux.
A new tool added to the kernel source tree with Linux 5.17 is rtla to serve for real-time Linux performance and tracing analysis.

The Linux kernel's frame-buffer device "FBDEV" subsystem has thankfully been on the decline over the past number of years thanks to the success of the more useful DRM/KMS drivers and having FBDEV compatibility emulation support. While not actively maintained, the FBDEV subsystem and some drivers remain within the Linux kernel and are used with some interest primarily in some legacy/embedded environments. The subsystem was orphaned while now a Linux kernel developer has stepped up to serve as its maintainer.
It's been over two years since Mumble 1.3 was released for this open-source VoIP / voice chat program that is popular with gamers and open-source enthusiasts while today it's been succeeded by Mumble 1.4.
Disclosed a few months back were "Trojan Source" attacks against compilers where specially crafted code could be rogue but not appear so due to exploiting Unicode issues. Unicode control characters could be used to reorder tokens in source code that could alter the behavior when compiled. With the upcoming GCC 12 compiler release there is a new warning to help point out possible Trojan Source attacks.
Sent in to the Linux kernel on Friday were the "char/misc" updates as the smorgasbord of kernel changes not fitting formally within other areas of the kernel. The char/misc changes range from AI accelerator driver updates to new Xilinx code to other random changes littered throughout.
