With Ubuntu 25.10 Canonical is planning to make use of more Rust-written system components and so far most of that talk has been about transitioning to Rust Coreutils "uutils" in place of GNU Coreutils. It's also been firmed up today that Canonical is planning on using sudo-rs by default as a replacement to sudo...

As part of fresh re-testing of existing laptops on-hand given the recent release of Ubuntu 25.04 and then also recent Linux reviews of some interesting models like the Framework Laptop 13 with AMD Strix Point and the Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition, I have been running a lot of Linux laptop benchmarks the past few weeks. I ended up taking things a bit further after those reviews and have now extended it to a 21-way laptop comparison of AMD Ryzen and Intel Core SoCs from the past few generations in looking at their performance on Ubuntu 25.04 across more than 200 benchmarks.

Longtime Linux kernel developer Ingo Molnar sent out a patch series this morning to enable additional kernel features by default for the Linux default configuration "defconfig" on x86-based kernels.

Introduced last year for Linux 6.13 was lazy preemption "PREEMPT_LAZY" for a preemption model that is similar to full preemption but less eager to preempt normal scheduler tasks to provide some of the performance benefits found with voluntary preemption. After initially being supported for x86_64 and RISC-V, it looks like Linux 6.16 will support lazy preemption on ARM64 (AArch64)...

This pull request contains a big new feature: the initial albeit currently experimental support for AMDGPU user mode queues...

Going back to last year an AMD engineer has been pursuing "Attack Vecotr Controls" to rethink CPU security mitigation handling. Attack Vector Controls aims to make it easier to manage CPU security mitigation settings by focusing on the class/scope of vulnerabilities rather than managing the mitigations at an individual level. It's looking like the initial attack vectors control code will be ready for mainlining in the upcoming Linux 6.16 cycle but stopping short of the complete implementation...

For anyone storing personal information on their laptops especially, I definitely recommend making use of Linux LUKS-based full disk encryption capabilities. I've been recommending going with the full disk encryption capabilities for nearly two decades to help protect personal data in case your laptop is lost or stolen. The performance implications of using full disk encryption have went down over time and in most real-world workloads you'll see minimal to any difference out of it. As it's been a while since running any reference benchmarks looking at no disk encryption to full disk encryption, here are some results on the newly-released Ubuntu 25.04 paired with the Framework Laptop 13 powered by AMD Ryzen AI 300 "Strix Point".

The Debian developer community is pursuing a General Resolution for voting on their policy around AI models...

In the event of your AMD Ryzen or EPYC system being randomly reset or unexpectedly rebooted under Linux, the Linux kernel with the upcoming Linux 6.16 cycle is gaining the ability to report the reason for that reset. This is making use of a technical capability found going back to the AMD Zen 1 processors that the Linux kernel is now tapping into for reporting the cause of any previous system reset...

Last year Redis made the much criticized move to Redis Source Available License v2 and Server Side Public License v1 (SSPL) licensing. The move was widely panned by the open-source community and led to the Linux Foundation forking it as Valkey and also other forks like Redict coming about. In the months since many Linux distributions have switched from Redis to Valkey. Now Redis Labs announced today that with the Redis 8.0 release, they are adding AGPLv3 to the licensing mix...

Ubuntu 25.10 "Questing Quokka" is now formally open for development...

With the recently released GCC 15 (GCC 15.1) compiler besides adding new language features, enhancements to help developers in debugging build failures, and other refinements, there is the never-ending quest of compiler performance optimizations. Since the recent GCC 15.1 release candidate I've been testing this annual compiler feature release on more hardware, including several AMD 5th Gen EPYC "Turin" servers to great success compared to the prior GCC 14 stable series.

Mediatek engineers have proposed Kcompressd as a new addition to the Linux kernel to improve the efficiency of memory reclamation. Mediatek engineers testing these patches on their handheld Linux devices have found huge benefit in alleviating memory pressure and enhancing system responsiveness...
