Today marks the ramp-down phase one point for JDK 21 where the OpenJDK code is forked from mainline for this de facto Java 21 implementation. Making OpenJDK 21 all the more exciting is this is going to be one of Oracle's bi-annual Long-Term Support (LTS) releases.
While AMD 4th Gen EPYC "Genoa" and Intel 4th Gen Xeon Scalable "Sapphire Rapids" processors launched a few months ago, for those not yet able to obtain the new processors/platforms, prefer waiting for DDR5 memory prices to recede further, don't necessarily need the latest bells and whistles found with these new server processors, or just looking to maximize value, 3rd Gen AMD EPYC Milan and Intel Xeon Scalable Ice Lake processors are readily available and still seeing plenty of new deployments in data centers throughout the world. In this article is a fresh look at the AMD Milan vs. Intel Ice Lake server performance, power efficiency, and performance-per-dollar across a range of processors.

SUSE engineer Nikolay Borisov sent out a set of patches today for "ia32_disabled" that would allow disabling of support for x86 32-bit processes from running on x86_64 Linux systems. As a first step this would be a boot-time option when "ia32_disabled" is set.

Given all the hype recently around generative AI, the Qt Group has begun exploring ways of incorporating generative AI into Qt.
Today marks nineteen years since I started Phoronix.com for covering the Linux hardware space. It's been a wild ride from the days of 56K modems, graphics driver pains, and having to use NDISWrapper for WiFi device driver support on Linux, among many other Linux hardware pains in the early days. These days the open-source GPU driver scene is far better off, Linux hardware support overall is great, companies continue investing massively into Linux/open-source thanks to the success in the server space over the past two decades, and the Steam Deck has proven to be one of the most interesting Linux-powered consumer devices in recent years.
In addition to announcing the Apple Vision Pro AR headset, a 15-inch MacBook Air, and other new hardware, Apple lifted the lid on the M2 Ultra SoC. The Apple M2 Ultra is impressive from the technical specs and hopefully won't be too long before it begins working under Linux.

The LLVM Fortran compiler "Flang" has begun seeing NVIDIA CUDA support land in the upstream code-base.
The ACO "Amd COmpiler" started by Valve for the Mesa RADV Vulkan driver has shown it can do wonders for Linux gaming performance and reducing game load times compared to AMD's official AMDGPU LLVM shader compiler back-end. Recently thanks to the work of Qiang Yu there has been much work hitting upstream Mesa for beginning to enable using the ACO compiler by the RadeonSI Gallium3D driver.
A new set of patches this weekend begin laying the groundwork for Rust abstractions for Linux network device drivers so that Rust code can be used for constructing new network device drivers. The patches also include a dummy Rust network driver.
One of the most interesting aspects of the new AMD Ryzen 7040 series laptop processors is the new "Ryzen AI" capabilities with the new XDNA AI engine capabilities built into the SoC, leveraging IP from their Xilinx acquisition. Linux support details remain scarce but at least one of their (Windows) demos for showcasing Ryzen AI is open-source.
On Friday a big set of patches affecting the AMDGPU/Radeon/AMDKFD kernel drivers were submitted for DRM-Next to queue until the Linux 6.5 kernel merge window opens in the coming weeks. A lot of new feature code is part of this pull for benefiting new hardware, continuing to refine AMD GPU power management under Linux, and more.
With Intel TDX and AMD SEV-SNP for better securing virtual machines on the mainline Linux kernel, memory is accepted/initialized immediately at boot time by the VMs although the capability exists to have "unaccepted memory" where that memory is only dealt with by the VMs later on or on an as-needed basis. For two years now Intel engineers have been working on this unaccepted memory support and this week posted their thirteenth iteration of these fundamental Linux kernel patches.
The Portable Computing Language "PoCL" began as an open-source CPU-based OpenCL implementation that has become quite a comprehensive implementation over the years. But in leveraging the LLVM/Clang compiler stack, over time PoCL has grown beyond just a CPU implementation to also support OpenCL execution on NVIDIA GPUs, AMD HSA-capable GPUs, and more. The latest now coming with PoCL 4.0 is support for Intel Level Zero execution for running this OpenCL implementation over Intel Arc Graphics GPUs.
Serpent OS started out as a new Linux distribution started by Ikey Doherty, the same developer that rose to fame for starting the Solus Linux distribution prior to a hiatus. Serpent OS was getting off the ground when the surprise full-circle announcement came in April that Solus Linux would build off Serpent OS.
KDE developer Nate Graham began his weekly development recap by noting that Plasma 6.0 development continues and its stability is improving daily as well as seeing new features.
