AMD FSR SDK 2.1 is now available that includes their "FSR Redstone" machine learning based upscaling tech for gaming

FSR SDK 2.1 ships with FSR Frame Generation 4.0, FSR Ray Regeneration 1.0, and FSR Radiance Caching in preview form. FSR Radiance Caching will officially debut in 2026.

Turbostat is the Linux command-line utility for reporting CPU frequency / power / C-states and related performance / power management items namely for modern AMD and Intel processors. This CLI utility lives within the Linux kernel source tree and for Linux 6.19 has picked up a few new features.

Turbostat in Linux 6.19 adds some new last level cache (LLC) statistics of: Last Level Cache Thousands of References Per Second "LLCkRPS" and Last Level Cache Hit % "LLC%hit".

In addition to approving Fedora Cloud switching /boot to a Btrfs subvolume , another change approved this week by the Fedora Engineering and Steering Committee (FESCo) is for shipping the Budgie 10.10 desktop packages in Fedora 44.

Fedora already enjoys Budgie in the package repository as an alternative desktop option. There is also the Fedora Budgie Spin for those wanting to enjoy the Budgie desktop experience out-of-the-box. Now for Fedora 44, it will get Budgie 10.10 thanks

The past several months Intel software engineers have been quite busy with LLM-Scaler as part of Project Battlematrix . LLM-Scaler is a Docker-based solution for AI workloads on Intel graphics hardware to ship an optimized vLLM stack and other AI frameworks. Out today is a new LLM-Scaler-Omni release to help enhance ComfyUI performance on Intel hardware.

There have been quite frequent updates to LLM-Scaler for expanding model coverage on Intel graphics hardware and delivering other new AI features for primarily the Arc "Battlemage" GPUs

A performance fix has been submitted to the Linux kernel for dealing with a regression in the Slab memory allocation code.

The sole patch with today's slab pull request for Linux 6.19 and to be back-ported to Linux 6.18 LTS stable is fixing a performance regression for code involving heavy kmem_cache_destroy() usage.

The kmem_cache_destroy() calls kvfree_rcu_barrier() that ends up flushing RCU sheaves across all slab caches when a cache is

While the Linux kernel has inclusive terminology guidelines for the past five years to replace phrases like master/slave and blacklist/whitelist, there has surprisingly been a "genocide" function within the kernel that was questioned when it was first submitted for inclusion but now removed in Linux 6.19.

Introduced to the Linux kernel back in 2023 was the d_genocide() function as part of various dcache updates to the kernel. The genocide name was questioned when the patches were first posted by longtime Linux

The Fedora Engineering and Steering Committee "FESCo" today signed off on a new feature for Fedora Cloud 44 to switch /boot to being as a Btrfs sub-volume rather than a separate partition.

Fedora Cloud moving forward will drop the separate /boot partition in favor of just using a Btrfs sub-volume for the directory. Though this functionality doesn't currently work for UEFI-UKI and s390x cloud images so there they will continue using the separate boot partition.

The argument in going for

The RISC-V CPU architecture changes have been merged for the in-development Linux 6.19 kernel.

With this new kernel RISC-V now supports CPU hot-plugging in parallel for secondary CPU cores. Secondary CPU cores can now be brought up asynchronously with the "HOTPLUG_PARALLEL" kernel feature now being supported on RISC-V for more quickly bringing up multiple CPU cores besides the primary CPU0. The CPU hot-plugging support particularly with RISC-V SoCs is primarily about dynamic enabling/disabling
