Being worked on for more than a year by Intel and other kernel developers has been FGKASLR to enhance kernel security. While the Linux kernel has long supported Address Space Layout Randomization (ASLR) to make memory addresses less predictable, FGKASLR ups the security much more by placing that randomization at the function level. It's looking like FGKASLR could be mainlined soon...

Linux 5.16 is an action-packed kernel with a ton of exciting additions and improvements. Adding to the growing list of changes to look forward to with v5.16 is mainline support for the Raspberry Pi Compute Module 4...

While it was initially communicated by Intel that Alder Lake's Golden Cove P-Cores has AVX-512 "fused off", that has turned out not to be the case at least with the initial batch of processors and current BIOS/firmware configurations. If disabling the power-efficient Gracemont E-Cores, it's possible to enable AVX-512 and make use of it. Here are some initial AVX-512 benchmarks in such a configuration under Linux with the Core i9 12900K.

Added to the Arch Linux ISOs earlier this year was Archinstall as an easy-to-use installer for Arch. In the months since its introduction the code continues to be improved upon and is preparing for its next feature release...

The "char/misc" changes have landed in Linux 5.16 as the catch-all area for code not fitting more appropriately within another subsystem or being a portion of the kernel that's too small for submitting pull requests directly to Linus Torvalds. For Linux 5.16, the IIO code has moved from being part of the staging area also maintained by Greg Kroah-Hartman to now being under the char/misc umbrella. Additionally, another big item is the Intel Habana Labs driver updates...

While we eagerly await the release of Godot 4 as a massive update to this leading open-source game engine, out this weekend is Godot 3.4 as a rather significant update to Godot 3.x with a number of new features and improvements...
