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.

LVFS Activity Going Wild Ahead Of New Security Disclosure Requiring Firmware Update
18 January 07:45 AM EST - LVFS - Linux Vendor Firmware Service - 16 Comments

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.

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.

Developer Steps Up Wanting To Maintain Linux's FBDEV Subsystem
Developer Steps Up Wanting To Maintain Linux's FBDEV Subsystem
16 January 07:22 PM EST - Hardware - Frame-Buffer Devices - 9 Comments

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.

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.

Mesa's V3D and V3DV drivers providing open-source OpenGL and Vulkan driver support, respectively, for newer Broadcom VideoCore hardware now has a double buffer mode implemented. This is a win for numerous workloads for these drivers most notably used by modern Raspberry Pi single board computers.

Ubuntu 22.04 LTS Planning To Stick With Linux 5.15 By Default
14 January 06:20 AM EST - Ubuntu - Linux 5.15 Kernel - 57 Comments

It turns out Ubuntu 22.04 LTS is planning to use the Linux 5.15 kernel as its default kernel. It makes sense in that Linux 5.15 is also a long-term support kernel, but unfortunate in that Ubuntu LTS releases haven't always used LTS kernel versions and v5.15 will be a half-year old already by the time the "Jammy Jellyfish" ships in April. This is a choice particularly unfortunate for those with recent hardware but at least there is the Ubuntu Mainline Kernel PPA and other non-default options available.

While the MIPS CPU architecture itself is at the end of the road, kernel developers still are busy with MIPS considering the Loongson hardware that is popular in China and lots of older MIPS hardware out there lacking mainline Linux kernel support. For Linux 5.17 several more older, consumer-grade network routers are seeing mainline support.
