There Is Another Attempt At Allowing Zstd-Compressed Firmware For The Linux Kernel

With Facebook's Zstandard compression algorithm becoming quite popular and well supported across many different environments -- including support for Zstd compressing the Linux kernel, among other uses -- there is a renewed effort in allowing Linux firmware to be compressed via Zstd.

In August of last year was a prior attempt for allowing Linux firmware to be Zstd compressed thanks to its faster decompression speeds of Zstd and thus allowing quicker boot times. Zstd firmware decompression was found to be much quicker than the likes of XZ.

That prior work never ended

NomadBSD 1.4 Working On An Improved Installer, Better Driver Detection

For those that have been trying to find a desktop-friendly BSD operating system that works smoothly out of the box but haven't yet found the perfect match, NomadBSD 1.4-RC1 is now available for improving this desktop-minded FreeBSD-derived open-source operating system.

NomadBSD 1.4 is working towards a number of improvements for bettering the initial out-of-the-box desktop experience. Besides shifting to FreeBSD 12.2-p2 as its base, NomadBSD 1.

Wayland 1.19 Released With Small Protocol Updates, Fixes

Wayland 1.18 released back in February 2020 while now nearly one year later it's been succeeded by Wayland 1.19.

Even with one year passing, Wayland 1.19 is a very minor update over Wayland 1.18. That's part of the reason why they moved off timed releases in the first place was the core Wayland code and protocol being quite stable at this point: there is very little change. Most of the work remaining to get Wayland ready

Experimental Patches Allow For New Ioctls To Be Built Over IO_uring

IO_uring continues to be one of the most exciting technical innovations in the Linux kernel in recent years not only for more performant I/O but also opening up other doors for new Linux innovations. IO_uring has continued adding features since being mainlined in 2019 and now the newest proposed feature is the ability to build new ioctls / kernel interfaces atop IO_uring.

The idea of supporting kernel ioctls over IO_uring has been brought up in the past and today lead IO_uring developer Jens

AMD Schedutil vs. Performance Governor Benchmarks On Linux 5.11 Shows More Upside Potential

With a pending patch, the Linux 5.11 AMD Zen 2 / Zen 3 performance is looking very good as far as the out-of-the-box performance is concerned when using Schedutil as is becoming the increasingly default CPU frequency scaling governor on more distributions / default kernels. With the previously noted Linux 5.11 regression addressed from when the AMD CPU frequency invariance support was first introduced, the Schedutil performance from small Ryzen systems up through big EPYC hardware is looking quite good. But how much upside


Linux 5.12 Bringing VRR / Adaptive-Sync For Intel TIger Lake / Xe Graphics

Finally with the upcoming Linux 5.12 cycle is support for Variable Rate Refresh (VRR) / Adaptive-Sync for Intel Tiger Lake "Gen12" Xe Graphics and newer.

The VRR/Adaptive-Sync support for the latest-generation Intel graphics with Tiger Lake and the likes of the forthcoming Rocket Lake, Alder Lake, and discrete DG1 graphics is now in order for the mainline kernel. The VRR enabling for Tiger Lake and newer was sent in this morning to DRM-Next ahead of the

Linux 5.10 LTS Will Only Be Maintained Until EOY 2022 Unless More Companies Step Up

Announced a few years ago was the notion of "extended" LTS kernel versions whereby the long term support cycle would span six years rather than the usual two years for LTS kernels in providing maintenance and bug/security fixes to the codebase. This means Linux 5.4 LTS is supported until the end of 2025, Linux 4.19 until the end of 2024, and even Linux 4.14 until the start of 2024. But with the recently minted Linux

AMD RDNA2 "Duty Cycle Scaling" Will Turn Off The GPU Under Heavy Load For Relief

A new Radeon power management feature with RDNA2 graphics processors being exposed by the open-source Linux driver is Duty Cycle Scaling in the name of power/thermal management with a focus on low-power hardware.

AMD graphics Duty Cycle Scaling is designed for "small power limit SKUs" and is designed to actually shut off the graphics core and power it back up based on current/power/temperature thresholds. Under heavy workloads, the AMD "DCS" functionality controlled by the graphics firmware will power down the GPU during

LLVM 12 Ends Feature Work With Better C++20 Support To Intel Sapphire Rapids + AMD Zen 3

Feature development on LLVM 12.0 has ended along with associated sub-projects like Clang and libc++. Feature work now shifts to LLVM 13.0 while the LLVM 12 stable release should be out in just over one month's time.

LLVM release manager Tom Stellard announced on Tuesday night that the 12.x release branch has been created and the main development trunk open to LLVM 13.0 feature work.

LLVM 12.0-RC1 is expected to be tagged

Unvanquished Open-Source Game Still Pushing Slowly Ahead In 2021

Nearly a decade ago we were intrigued by Unvanquished as one of the most interesting open-source game/engine projects of the time. It was peculiar in going through dozens of alpha releases prior to drying up a few years ago. There hasn't been any major release yet past the prior alpha state but the project is in fact still moving along and issued their first new (point) release of the year as well as rolling out a new online updater.

In 2020 we were pleased to see
