It's pretty rare to see Linus Torvalds author patches himself pertaining to the open-source Linux graphics drivers, but waking up this morning I was surprised to see he authored and committed an Intel Xe kernel graphics driver change himself. It ended up being after he encountered a "debug session from hell" but was ultimately helped by AI in fixing a bug that had been irking him...

Intel's open-source Mesa drivers for Iris Gallium3D (OpenGL) and ANV (Vulkan) on Linux are no longer treating next-gen Nova Lake processors with integrated graphics as experimental and off-by-default. With today's Mesa 26.3-devel code, the Intel driver code across Nova Lake's S, U, H, and HX product families are considered stable and enabled by default...

All of the networking subsystem feature updates were merged today for the Linux 7.3 kernel's merge window. There are a lot of wired and wireless networking improvements this cycle but also a ton of bug fixes -- including many not so important fixes spun up by AI/LLM agents. The networking subsystem maintainers admit now they are "completely overwhelmed" due to this code churn from the output of AI large language models...

Rust 1.98 released today and is headlined the debut of new algebraic floating-point methods...

KMSCON 10.0.2 debuted today as the latest update to this leading user-space terminal emulator for Linux systems. KMSCON is built around Linux's KMS/DRM interfaces and the most viable alternative to date for in-kernel VTs...

With the Intel Xeon 678X "Granite Rapids WS" processor that I have been recently testing within the HP Z4 G6i workstation, there are 48 cores plus with Hyper Threading is a total of 96 threads for this high-end workstation processor with a 300 Watt TDP. For those curious about the performance impact of HT/SMT on this Intel Xeon 600 series workstation processor, here are some comparison benchmarks.

FSCRYPT is the Linux file-system encryption framework for supporting per-directory, transparent encryption. FSCRYPT so far is used by the likes of EXT4, F2FS, and CephFS. For Linux 7.3 there is an important clean-up to the FSCRYPT code to simplify it while also opening the door for new features moving forward into future kernel versions...

The Linux kernel has supported the CONFIG_COMPAT_32BIT_TIME Kconfig build time option for optionally disabling of legacy 32-bit time system call support. This is intended to disable the code that uses a 32-bit integer for time that is thus not Year 2038 safe, but at the cost of breaking compatibility for legacy 32-bit applications. Even if building without Linux 32-bit time support, it turns out some 32-bit time code persisted but that is now being fixed with Linux 7.3...

KDE Gear 26.08 was released today to deliver the latest collection of KDE application updates...

Following today's release of XWayland 26.1 RC1, X.Org Server 26.1 RC1 was tagged. This xorg-server 26.1 release is aiming to become the first major feature release in five years, succeeding the xorg-server 21.1 series...

In addition to the IOmap improvements helping EXT4 performance in Linux 7.3, the main EXT4 feature pull request has now been submitted for this next kernel version. That pull is set to land yet more performance optimizations for EXT4...

Andrew Morton on Tuesday sent out all of the memory management "MM" updates for the Linux 7.3 merge window. The MM pull was particularly heavy as he noted 1,250 "added-to-MM" emails were sent out this cycle compared to 920 the prior cycle. With a lot of patch churn, he also turned to Google's Gemini AI for writing his patch summaries. In going through the very verbose AI-generated summary, there are two patch series that get me excited on the performance front with Linux 7.3...

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...

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...

The XFS file-system improvements have been merged for Linux 7.3. For end-users the only notable change for this file-system on the new kernel is adding support for FALLOC_FL_WRITE_ZEROES...

Among the early pull requests merged today by Linus Torvalds for the Linux 7.3 kernel cycle were removal of some ancient file-systems while adding in a new pseudo file-system...

Earlier this year Natalie Vock of Valve's Linux graphics team laid out some patches for improving the Linux gaming experience for systems with limited vRAM. The kernel work for improving that video memory management is set to be introduced in the Linux 7.3 kernel. While that's a celebration on its own, Vock is pursuing more improvements still for bettering the Linux GPU driver video memory management behavior...

The FFmpeg multimedia library can now enjoy faster H.265/HEVC video encoding with the Vulkan-powered encode path. With the optimizations merged today, the H.265 encode performance should be roughly at parity to the H.264 encode speed...

A new research paper published on LLVM offloading to GPU accelerators using the Rust programming language is talking up the prospects of making use of safe Rust code for GPU kernels while retaining Rust's memory safety and other advantages over C++ / CUDA / HIP...

Back in March were patches posted by ARCTIC Cooling for an ARCTIC fan controller driver for Linux. Typically we aren't used to seeing desktop/enthusiast focused vendors providing such Linux drivers for peripherals directly but the sad fact is most often it's left up to the open-source community to reverse engineer and create such drivers for Linux. Making it all the more surprising besides it coming from ARCTIC Cooling directly was that at the time they didn't even have a fan controller product with USB interface. Well, now it's launched and in turn is a great USB fan controller for Linux systems and retails for just $9 USD.

AMD engineers are working on enhancing the open-source ROCm compute stack for better handling GPU virtualized compute under QEMU...

KTransformers as the framework for heterogeneous LLM inference and fine-tune optimizations is out today with its v0.7 feature release...

Huge surprise this morning! Longtime Linux users may recall the out-of-tree work done years ago by open-source developer Con Kolivas... And as part of that his work on the Brain F*** Scheduler that evolved into the MuQSS scheduler, all in the name of working to improve Linux desktop and mobile responsiveness. While a number of years ago he decided to retire from this out-of-tree Linux kernel work, out of the blue he announced a new -ck patch series today with updated MuQSS code...

The PowerPC pull request has already been sent in for the now open Linux 7.3 merge window. The headline feature this cycle on the POWER side is Rust kernel support for PowerPC 32-bit PPC32BE big endian and PowerPC 64-bit PPC64LE little endian architectures...
