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.
