Go 1.27 was released today as the newest version of this programming language from Google's Go team.

David Sterba of SUSE sent in the Btrfs file-system feature updates today that target the Linux 7.3 merge window. Among other changes are more performance improvements for this next version of the Linux kernel.

With today's memory prices, a frequent question at Phoronix and throughout many organizations is about reducing cost by not necessarily populating all memory channels. Especially with modern servers going up to 12 memory channels per socket or even 16 memory channels with upcoming EPYC Venice, you may be curious about the performance impact of populating less memory channels to see if the trade-off is worthwhile given today's DDR5 RDIMM pricing. In this article are benchmarks from a Dell PowerEdge server looking at a dual AMD EPYC 9655 2P configuration when testing between four and the full twenty-four DDR5-6400 RDIMM configuration and the resulting performance impact in more than 250 benchmarks.

Olivier Fourdan of Red Hat announced today the first release candidate of XWayland 26.1. This is the first new tagged feature release since XWayland 24.1 back in 2024! As such there are many new features in tow.

All of the SoC updates have been merged for the Linux 7.3 kernel that include adding some new SoCs as well as deprecating several older 32-bit ARM platforms. In turn with those platforms deprecated, "hundreds" of drivers are now orphaned in the process.

A Phoronix Premium supporter recently relayed a request to see some fresh PHP performance benchmarks. So here are some fresh numbers of PHP 7.4 through the latest PHP 8.5 code plus the current Git state of PHP 8.6 ahead of the official PHP 8.6.0 release later in the year. With PHP 8.6 is also a fresh look at the JIT performance enabled too.

The exciting set of scheduler updates have been merged for the Linux 7.3 merge window.

Covered first on Phoronix back in June was an AMD Linux patch for introducing a new "low power" CPU core type to complement their typical "performance" cores and their "efficiency" cores like with Zen 4C/5C. That low power core is presumed for some Zen 6 clients and that integration is now merged for Linux 7.3 as well as unifying the Intel/AMD CPU core type handling.

The newest Raspberry Pi product to launch is the Raspberry Pi Compute Module 5 Programming Jig.

Modular, the AI startup founded by Chris Lattner of LLVM and Swift fame, has open-sourced their Mojo systems programming language! This comes following the recent acquisition of Modular by Qualcomm.

COSMIC Epoch 1.6 was released this evening as the latest milestone for this open-source, Rust-based desktop environment led by System76 as part of the work on their Pop!_OS Linux distribution.

Merged earlier this year for Linux 7.1 was extended attributes on sockets support as a feature sought after by the likes of GNOME and systemd for helping with Varlink IPC usage and other purposes. A limitation though of the functionality has been no efficient means for a BPF program to read those user extended attribute labels back. But with Linux 7.3 that's being addressed with the new bpf_sock_read_xattr() kernel function.

As part of the VFS pull requests now merged to the Linux 7.3 development kernel was an improvement to the IOmap framework used by various file-systems for mapping logical file byte offsets in memory to their physical locations on storage. With the now-merged code, this modern block mapping framework is allowing better performance at least for the EXT4 file-system.

Last year Framework Computer launched the Framework Laptop 12 as an upgrade-friendly and Linux-compatible 2-in-1 laptop. The Framework Laptop 12 was originally powered by Intel Core 13th Gen "Raptor Lake" low-end processor while now Framework is adding Core Series 3 "Wildcat Lake" as an upgrade or for new Laptop 12 orders.

Recently I looked at the performance of Ubuntu 26.04 LTS vs. Windows 11 on the Intel Xeon 678X running within the HP Z4 G6i workstation. Linux performed admirably as one would expect. With this Intel Xeon Granite Rapids WS workstation from HP though commanding a retail price more than $46,000 USD, you likely want nothing but the utmost performance out of it. So for those looking to maximize the OS performance, here are some numbers from the HP Z4 G6i workstation when running not only Ubuntu 26.04 LTS but also Fedora Workstation 44, AlmaLinux, and the performance-optimized CachyOS.

In addition to the POWER/PowerPC code adding Rust kernel support, the main set of Rust programming language updates for the Linux 7.3 kernel have now been submitted. Most notable are early fixes toward eventually allowing the experimental Rust GCC back-end to be used as an alternative to the official rustc compiler with LLVM code generation.

It's not too often that the Linux FAT driver for FAT12/FAT16/FAT32 format support receives updates worth mentioning. For Linux 7.3 there is one patch though and it's due to the driver until now lacking an upper-bounds check on the length of the filename, which could lead to some unexpected situations with extremely long filenames.

There was a proposal under discussion the past few months on building x86-64-v3 packages for Fedora 45 while retaining x86-64-v1 packages. The hope was building the Fedora packages with x86-64-v3 where AVX/AVX2, FMA, BMI2, and other newer ISA features can be assumed in the name of better performance. Unfortunately, the x86-64-v3 plans are now delayed but may be reconsidered next year with Fedora 46.

When it comes to the watchdog driver changes for Linux 7.3, standing out is the new Lenovo driver for their upcoming ThinkEdge AI edge computing systems.

Merged today to Mesa 26.3-devel is a nice performance boost for Intel graphics with Valve's Steam Play when using DXVK for Direct3D 8 / 9 / 10 / 11 over the Vulkan API. The open-source Intel ANV driver is seeing up to 5% better performance with DXVK.
