SiFive's HiFive Unmatched is the best, readily available RISC-V developer board at the moment with enough horsepower for modest development/porting work and continues seeing improvements with the mainline Linux kernel. But availability on HiFive Unmatched is beginning to dry up and SiFive isn't planning on any further production runs as it begins focusing on the board's successor.

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.

Linux 5.17 Making It Easier To Build A Kernel With All The Shiny Debug Features
Linux 5.17 Making It Easier To Build A Kernel With All The Shiny Debug Features
20 January 06:19 AM EST - Linux Kernel - Linux 5.17 debug.config - 6 Comments

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.

19 January 07:43 PM EST - Linux Storage - Linux 5.17 F2FS - 22 Comments

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.

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.

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.

GCC 12 Ready To Help Fend Off Trojan Source Attacks
16 January 08:00 AM EST - GNU - -Wbidi-chars - 13 Comments

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.
