The USB and Thunderbolt changes have been merged for Linux 7.3. Two changes stand out for me in the USB subsystem code with Linux 7.3. First, the kernel arguably being long overdue for checking USB-C cables capabilities whether they support alt-modes. Second, a new low-latency USB4STREAM option for lower latency data transfers between USB4-connected systems...

The char/misc changes were merged this week for the Linux 7.3 cycle. While there is a lot of IIO driver churn as usual and updates to the likes of the Google Binder drivers, there continues to be the 2026 trend of removing old hardware drivers that are rarely updated these days and likely have no active users left on the mainline Linux kernel. This trend is further pushed along by the surplus of AI/LLM-generated bug reports and patches these days causing additional maintenance burden for these obsolete drivers...

Canonical today published Ubuntu 26.04.1 LTS as their first point release in the long-term support series for the "Resolute Raccoon"...

Over the past year and a half a number of open-source drivers in the Linux kernel have been orphaned as a result of departures from the company. The impact has ranged from the Intel CPU "coretemp" temperature driver being orphaned without a maintainer to other lesser known Intel drivers. Another lesser known Intel driver is now being orphaned with no longer having a maintainer at the company: the Intel Specific Absorption Rate Driver...

It was back in May that the surprising event happened of AMD posting HDMI 2.1 FRL patches for their open-source AMDGPU Linux driver as part of their broader HDMI 2.1 bring-up. For years the open-source HDMI 2.1 support in AMDGPU was blocked by the HDMI Forum but whether it was due to Valve or some other event, the code was finally unblocked. While it's been part of the kernel since Linux 7.2, it's been disabled by default -- except that is now changing...

Following last week's main set of memory management "MM" related updates for Linux 7.3, another batch of MM code updates were submitted and merged today as we prepare to close out the Linux 7.3 merge window. There are a few optimization patches that stand out along with other mostly small fixes/changes...

Back in July ROCm 7.14 was announced as their new production release built atop TheRock build system and introducing Ryzen AI 400 series support. The versioning choice was a bit odd since ROCm 7.2 was the stable release at the time while ROCm 7.9+ turned into "tech preview" releases. With ROCm 7.14, it was declared stable. In clearing up that versioning mess, they have done a major version bump... to ROCm 10.0...

Earlier this week I showed off some of the very nice Btrfs performance gains on Linux 7.3. For those wondering what kernel optimizations may have carried over to other file-systems or other file-system specific enhancements, here are Linux 7.2 vs. 7.3 Git performance benchmarks across Btrfs, EXT4, F2FS, and XFS on the same system.

With the never-ending quest for greater I/O performance in the HPC space and the demands all the more relentless in the AI era, the Linux kernel block subsystem activity continues to be as vibrant as ever along with the ongoing innovations in the IO_uring space...

Last week I provided a look at the Intel Xeon 600 series Hyper Threading performance with the Xeon 678X "Granite Rapids WS" processor for HT/SMT on and off. That was interesting while another reader request was to look at the CPU core scaling performance for this high-end workstation processor. Here are those benchmarks for showing the performance, power, and frequency/thermal impact of the Xeon 678X when limited to 6 cores, 12 cores, 24 cores, 48 cores, and then the 48 cores + HT default configuration.

Haiku R1 Beta 5 came out in September 2024 while out today is the long-awaited sixth beta for this open-source operating system inspired by BeOS. This beta release also comes one week ahead of the project's 25th anniversary...

AMD's compiler team is proposing a new LLVM Clang compiler option, -fenable-readonly-thp for implementing instruction Transparent Huge Pages "iTHP" at compile and link-time. With -fenable-readonly-thp, they are finding more performance out of SPEC CPU, Geekbench, and other workloads from the arranging of 2MB segment alignment at link time and allowing the executable text range can be promoted to huge pages...

Earlier this month when benchmarking six Linux distributions on the new Framework Laptop 13 Pro powered by Intel Core Ultra Series 3 "Panther Lake", the performance was strangely slow on Fedora Workstation 44. When digging further into it, the performance loss was with Fedora 44 using Tuned-PPD by default where as other Linux distributions default to Power Profiles Daemon. Ultimately, after Red Hat engineers got involved, was found to be a bug within the Intel P-State kernel driver exhibited by Tuned-PPD. The latest Linux kernel already has a fix in place and will be back-ported to Fedora 44...

Last year a multi-kernel architecture was proposed for the Linux kernel to allow multiple independent kernel instances to co-exist on a single physical machine. Each kernel with "multikernel" Linux can run on dedicated CPU cores whole sharing the underlying hardware resources. Linux 7.0-mk2 released today with the kernel patched for this multi-kernel behavior...

As part of that they developed a window manager / compositor benchmark for evaluating the performance and efficiency of typical operations. Their results are fascinating...

The latest criticism of the increased burden placed on open-source software project maintainers caused by AI / LLM agents is around too many bug reports effectively causing a "denial of service" attack on project maintainers...

With the Btrfs pull request for Linux 7.3 having delivered more performance optimizations with some ~3x and ~5x gains mentioned in specific areas, I was eager to test out the new Btrfs performance on the in-development kernel. In today's article are some benchmarks of Btrfs on Linux 7.2 stable compared to Linux 7.3 Git with some very enticing performance gains confirmed in various workloads.

The past few Linux kernel cycles have chipped away at AF_ALG functionality for that interface for user-space programs to access the kernel's internal cryptography API. Linux has been dropping AF_ALG features like zero-copy support and offloading. AF_ALG was quickly deprecated in Linux 7.2 while now for Linux 7.3 it's being further restricted...

Being halfway through the Linux 7.3 kernel merge window and prior to wrapping up and sending back the HP Z4 G6i workstation powered by the Xeon 678X Granite Rapids WS processor, I decided to run some benchmarks to see how Linux 7.3 Git is performing relative to the prior stable kernel series. Here are the first benchmarks of this early state of Linux 7.3 with some performance improvements as well as some regressions.
