Canonical To Distribute AMD ROCm Libraries With Ubuntu 26.04 LTS

Phoronix | Dec. 9, 2025, 1 p.m. | Original

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.

In collaboration with AMD, Canonical will be

Linux Foundation's Newest Endeavor: The Agentic AI Foundation

The Linux Foundation today announced it's formed another foundation under its growing umbrella that extends well beyond the traditional "Linux" landscape: the Agentic AI Foundation.

The Agentic AI Foundation "AAIF" has been formed with Anthropic contributing the Model Context Protocol (MCP), Block's goose, and OpenAI contributing their AGENTS.md specification for guiding coding agents.

The Agentic AI Foundation aims for " a neutral, open foundation to ensure agentic AI evolves transparently and collaboratively. "

With Firefox 146 released, which is exciting for delivering fractional scaling on Wayland , Firefox 147 Beta is now available and it's also quite exciting to Linux users for another reason.

Firefox 147 Beta is exciting in finally shipping XDG Base Directory specification support for the Linux build! As covered last month, Mozilla is finally supporting the XDG Base Directory specification in Firefox . To date Firefox has just positioned all files under ~/.mozilla rather than the likes of ~/.config and ~

Scheduler Woes: Bisecting Early Performance Regressions Found In Linux 6.19

Phoronix | Dec. 9, 2025, 11 a.m. | Original

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

AMD today announced their newest member of their expansive EPYC family: the EPYC Embedded 2005 series. The new AMD EPYC Embedded 2005 Series are intended primarily for networking, storage, and industrial devices while these BGA processors will likely see other interesting thin-server uses as well.

The AMD EPYC Embedded 2005 series are built on Zen 5 cores from eight to sixteen cores and with TDPs from 45 to 75 Watts. The EPYC Embedded 2005 series are BGA 4

Microsoft Has Many Hyper-V Virtualization Improvements For Linux 6.19

Phoronix | Dec. 9, 2025, 9:30 a.m. | Original

For benefiting their Azure cloud and other users of Hyper-V virtualization at large, Microsoft has rolled out a number of feature additions and improvements for their Hyper-V kernel code in Linux 6.19 .

Last week Microsoft's RAMDAX driver was upstreamed to the Linux kernel while this week the Windows company sent in a number of Hyper-V improvements for this next version of the kernel. The Hyper-V pull landed more work around confidental computing "CoCo" for VMs, secure AVIC support for Linux guests

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

Phoronix | Dec. 9, 2025, 6:17 a.m. | Original

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.

The Smatch static analysis on the kernel in recent years has been led by Dan Carpenter while working

Linux 6.19 Enables Per-CPU BIO Caching By Default For Helping Performance

Phoronix | Dec. 9, 2025, 5:59 a.m. | Original

Last week saw the main set of block and IO_uring feature patches for the Linux 6.19 merge window but some additional block subsystem material was merged on Monday. There are various NVMe updates now merged plus enabling per-CPU BIO caching by default to help with file-system performance.

From this merge mostly about landing the NVMe fature updates for Linux 6.19, there's also patches for enabling the per-CPU BIO caching by default. That turns out to be interesting for helping with

F2FS Brings More Performance Optimizations To Linux 6.19

Phoronix | Dec. 9, 2025, 5:42 a.m. | Original

The Flash-Friendly File-System "F2FS" is enjoying more performance optimizations and other improvements for the Linux 6.19 kernel cycle.

Jaegeuk Kim submitted the F2FS feature updates on Monday for the Linux 6.19 merge window and they were pulled into the codebase overnight by Linus Torvalds. No particular standout fearture this cycle but there are various performance optimizations.

The Git merge sums up the F2FS activity as:

"This series focuses on minor clean-ups and performance optimizations across
