Scheduler Woes: Bisecting Early Performance Regressions Found In Linux 6.19

Yesterday I noted some early performance regressions I’ve found on the Linux 6.19 kernel compared to Linux 6.18 LTS stable. Those initial benchmarks were on an AMD EPYC server. Since then I’ve seen many of the same workloads regressing similarly on an AMD Ryzen Threadripper workstation between Linux 6.18 and Linux 6.19 Git. Given the significant impact and AMD Threadripper processors always helping out to speed-up Linux kernel build times to make for a quicker and more manageable kernel bisecting experience, here is a look at some of the results for the Linux 6.19 performance regressions.

Canonical To Distribute AMD ROCm Libraries With Ubuntu 26.04 LTS

AMD previously talked of simplifying the in-box Linux support for ROCm during the second half of 2025. So far we haven’t seen any groundbreaking changes from that initiative besides AMD working on various package archives/repositories to make it easier to install the latest ROCm on different Linux distributions. But today a big announcement is now public that Canonical with next year’s Ubuntu 26.04 LTS release will provide official ROCm packages along with other libraries…

[$] Bazzite: a gem for Linux gamers

One of the things that has historically stood between Linux and the
fabled “year of the Linux desktop” is its lack of support for video
games. Many users who would have happily abandoned Windows have,
reluctantly, stayed for the video games or had to deal with dual
booting. In the past few years, though, Linux support for
games—including those that only have Windows versions—has
improved dramatically, if one is willing to put the pieces
together. Bazzite, an image-based
Fedora derivative, is a project that aims to let users play games and
use the Linux desktop with almost no assembly required.

Firefox 146 released

Version
146.0
of the Firefox web browser has been released. One feature of
particular interest to Linux users is that Firefox now natively
supports fractional scaled displays on Wayland. Firefox Labs has also
been made available to all users even if they opt out of telemetry or
participating in studies. “This means more experimental features
are now available to more people.
“

This release also adds support for Module-Lattice-Based
Key-Encapsulation Mechanism (ML-KEM) for WebRTC. ML-KEM is
“believed to be secure against attackers with large quantum
computers
“. See the release notes for all changes.

Bug-Catching “Smatch” Static Analysis On The Linux Kernel Under Threat Due To Funding Gap

For the past 15 years the Smatch static analysis tool has been routinely run for uncovering countless bugs within the Linux kernel. Dan Carpenter who authored Smatch and has been routinely analyzing the Linux kernel with it has authored more than 5,568 patches over the years to become one of the top bug fixers for the kernel. But his funding at Linaro has been cut and the project’s future now in question…

Rust-Based Project Aims To Provide Modern Thumbnails For Audio/Video Files On GNOME

Since Showtime replaced Totem as the default video player of GNOME, the desktop has lacked thumbnail capabilities for audio and video files. But to address that defect, the Rust-based gst-thumbnailers project has been in development to leverage GStreamer and paired with Rust to provide safe thumbnail generation capabilities for audio and video content…
