Linus Torvalds just promoted Linux 6.0 to stable on-schedule and thereby now ushering in the Linux 6.1 merge window to officially get underway tomorrow.

Linux 6.0 is bringing many great features but looking ahead for Linux 6.1 there are even more changes to get excited about for that kernel which will release as stable around the end of 2022.

Improving the mainline Linux kernel support for the PinePhone is a keyboard driver expected to land for the imminent Linux 6.1 merge window.

Along with the Rust infrastructure for Linux 6.1 pull request, another early pull submitted by kernel maintainer Kees Cook for Linux 6.1 is the introduction of a new Control Flow Integrity "CFI" implementation for the Linux kernel to replace the former, less-than-ideal code.

Barring any last minute reservations today by Linus Torvalds, the Linux 6.0 stable kernel is expected to be christened before the day is through. Linux 6.0 comes with many notable hardware support additions and other improvements, here is a reminder of all what is great about this imminent kernel release.

Debian developers have been figuring out an updated stance to take on non-free firmware considering the increasing number of devices now having open-source Linux drivers but requiring closed-source firmware for any level of functionality. The voting on the non-free firmware matter has now concluded and the votes tallied...

AMD on Friday upstreamed new Family 19h CPU microcode to linux-firmware.git.

While the Steam on Linux marketshare has been consistently increasing this year since the launch of the Arch Linux powered Steam Deck, the September 2022 numbers are in and surprisingly there is a slight pull-back in Linux use.

System76 has been developing their own COSMIC desktop as the next evolution for their Pop!_OS Linux distribution built atop an Ubuntu base. Interestingly with this big COSMIC desktop undertaking, which is being written in the Rust programming language, they have decided to shift away from using the GTK toolkit to instead make use of Iced-Rs as a Rust-native, multi-platform graphical toolkit.

It's happening, folks! Linus Torvalds already indicated recently he intends to pull the initial Rust programming language support into the Linux 6.1 kernel cycle and today that pull request was submitted to him. Linux 6.0 isn't out yet but should be on Sunday unless any last minute problems, which in turn will mark the start of the two week v6.1 merge window.

Last year Google announced the Lyra voice codec for low bit-rates that combined with the open AV1 codec could lead to voice chats on 56kbps connections. Lyra makes use of machine learning and other techniques for extremely low bit-rate speech compression that can function at 3kbps. Google last year open-sourced the Lyra code while today they announced the availability of Lyra V2.

While some Linux enthusiasts eagerly recommend users boot their systems with the "mitigations=off" kernel parameter for run-time disabling of various relevant CPU security mitigations for Spectre, Meltdown, L1TF, TAA, Retbleed, and friends, with the new AMD Ryzen 7000 "Zen 4" processors while still needing some software mitigations, it's surprisingly faster for the most part leaving the relevant mitigations enabled.

Currently Linux's Logitech HID++ driver "hid-logitech-hidpp" relies on a static list of device quirks for indicating which Logitech mice support high resolution scrolling. With the upcoming Linux 6.1 kernel, the plan is to change that list of devices/quirks and to automatically determine if a device supports high resolution scrolling.

Linux 6.0 should be released as stable on Sunday unless Linus Torvalds has last minute reservations and decides to extend the cycle by an extra week.

Along with that has been a number of glthread-related improvements to this code that punts executing OpenGL calls to a separate CPU thread. The Zink OpenGL-on-Vulkan driver has now unconditionally enabled OpenGL threading too.

For Fedora Linux users currently making use of Mesa's VA-API support with the open-source AMD graphics driver or similar and using it to speed-up H.264, H.265, or VC1 decoding, you may soon be out of luck and will have to fall-back to either using CPU-based decoding or be relying on an unofficial/third-party Mesa build.
