Last year AMD launched the EPYC 4004 series for taking Ryzen based processor designs into the EPYC segment for entry-level servers with ECC memory support, server designs with BMCs, and various enterprise software certifications and industry qualifications. Today they are launching the EPYC 4005 series as their new Zen 5 based offerings for entry-level / budget server deployments and other instances when not needing as much compute power or connectivity and other high-end features found with the EPYC 9005 "Turin" processors.

Canonical provided a status update concerning the Qualcomm Snapdragon X Elite powered laptops on the recently released Ubuntu 25.04.

The Mozilla Firefox source code is now officially available on GitHub as they work to transition from their hg.mozilla.org servers.

Merged for the Mesa 25.2 release next quarter are some further enhancements to the Vulkan ray-tracing support with the RADV open-source driver for AMD's new RDNA4 graphics cards.

The Rust-written NAK shader compiler used by Mesa's NVK open-source Vulkan driver for NVIDIA GPUs has merged support for SM32 as the "KeplerB" / Kepler 2.0 graphics processors.

GNU Screen 5.0.1 has been released to address several security issues.

Following Monday's public disclosure of the "Training Solo" security disclosure for this set of issues affecting multiple generations of Intel processors, new Intel CPU microcode has been released for Linux users as part of the mitigation process.

The BeOS-inspired Haiku open-source operating system project has published their April 2025 progress report.

The VUSec security researchers are at it again... The embargo is now lifted on another set of of security vulnerabilities affecting Intel processors as well as Arm core designs. This new vulnerability is dubbed Training Solo.

We finally have AMD's Strix Halo in the lab for benchmarking! HP has kindly sent over their ZBook Ultra 14-inch G1a mobile workstation: it's a beast being powered by the top-end AMD Ryzen AI Max+ PRO 395 SoC with 16 cores / 32 threads and powerful integrated Radeon 8060S graphics, 128GB of system memory, a nice 14-inch 2.8K display, and other top-end features to provide a dominating laptop powerhouse. In today's article are the very initial benchmarks of the AMD Ryzen AI Max+ PRO 395 Strix Halo SoC under Linux with a focus on the CPU capabilities: a separate article also out today is looking at the AMD Radeon 8060S graphics on Linux.

As shown in today's article the AMD Ryzen AI Max+ PRO 395 Linux performance is incredible with its 16 Zen 5 cores delivering staggering laptop / mobile workstation performance with a 55 Watt default TDP. But that's only half the magic of Strix Halo, with the other aspect being the very capable integrated RDNA 3.5 graphics with unified memory support. Given this being an equally interesting topic for Linux users considering a Strix Halo laptop or desktop, this article is centered around the integrated Radeon 8060S graphics support and performance under Linux.

At the end of April was the open-source surprise of NVIDIA posting Nouveau Linux driver patches for their Hopper and Blackwell GPUs. This comes to complement their official (open-source but out of tree) kernel driver support for these newer NVIDIA GPUs and in the absence of the modern Rust-based NOVA Linux kernel driver not being in working shape yet on the mainline kernel. An updated version of these Nouveau driver patches for NVIDIA Hopper and Blackwell GPUs were posted overnight.

Queued within the development tree for the RISC-V processor code for the Linux kernel is supporting several new vendor-specific ISA extensions for SiFive RISC-V CPU cores.

While it took two and a half years for DragonFlyBSD 6.4.1 to materialize from DragonFlyBSD 6.4, only one week passed since that recent v6.4.1 release to now see v6.4.2.

Shotcut 25.05 was released on Sunday as the newest feature release for this non-linear, open-source video editing software.

Linus Torvalds has released Linux 6.15-rc6 today with hopes of releasing Linux 6.15 stable in two weeks.

At the end of April I reported on a significant performance regression affecting newer AMD CPUs and was bisected to a change in the AMD SRSO mitigation handling for Zen 4/5 processors with the Linux 6.15 kernel. The fix for that significant performance regression was merged today ahead of the imminent Linux 6.15-rc6 release.

Merged today to Linux Git ahead of the Linux 6.15-rc6 release is support for several more gaming controllers.

A number of Phoronix readers have been inquiring in recent weeks around seeing updated Linux graphics/gaming benchmarks for the Intel Arc B-Series "Battlemage" graphics cards. So for your viewing pleasure today is a look at the Arc Graphics B580 and B570 graphics cards on Ubuntu 25.04 for showing how the graphics performance have improved with the open-source Intel Linux graphics driver stack since launch.

This week Google announced all of the accepted projects for this year's Google Summer of Code (GSoC). There are 1,272 accepted students/projects this year for student developers working on various interesting open-source efforts over the summer.
