Amazon Linux 2027 Shows Off Nice Performance Gains On AMD EPYC In The AWS Cloud

Yesterday AWS announced the public preview of Amazon Linux 2027 as their successor to the current Amazon Linux 2023 in-house distribution. With all the software upgrades and improvements like building packages now with link-time optimizations (LTO), enforcing x86-64-v3 builds, and other changes, I was eager to run some performance benchmarks of Amazon Linux 2023 vs. Amazon Linux 2027 in the EC2 cloud.

NetworkManager Works To Enforce AI Policy By Tricking AI Agents To Add A Canary

Last month the NetworkManager project adopted an AI coding policy where authors are responsible for 100% of the code they submit and must be able to explain it all. In an attempt to catch AI coding agents that may be trying to bypass their policy, they have added an interesting canary to the project to try to catch such AI-generated patches so they can then be automatically dealt with...

Linux 7.4 To Improve Apple Silicon Audio Support & Its "Impossible" Power Management

The Apple Silicon audio driver code within the Linux kernel is preparing to make use of the recent shared GPIO infrastructure for allowing multiple drivers / kernel components to nicely share the same GPIO lines. This should help clean things up in the mainline kernel for the Apple Silicon audio support and with a cleaner architecture than the current downstream Asahi Linux code...

Fedora 47 Considering Use Of Thin LTO Compiler Optimizations

A change proposal filed for what would be part of Fedora Linux 47 is on making use of Thin LTO rather than Fat LTO for link-time optimizations. With Thin LTO being more memory efficient and faster build speeds, the hope is that more Fedora packages could also use Thin LTO for packages where no link-time optimizations are currently leveraged...

Intel Improving Its Content Match Refresh Rate "CMRR" Feature With Linux 7.4

Introduced with the Xe2 Lunar Lake graphics hardware was support for Content Match Refresh Rate (CMRR) as an improvement over typical Variable Refresh Rate (VRR) / Adaptive-Sync to more precisely match the video or content frame rates. Particularly for video playback it aims for no stuttering or frame drops. With the upcoming Linux 7.4 kernel will be better support for CMRR with the Intel graphics driver...

21st Revision Of Patches For Getting Linux To Shutdown Devices Asynchronously

Being worked on for over two years has been the latest attempt for async device shutdown support for Linux for getting Linux systems -- especially servers with lots of hardware like many NVMe drives -- to shutdown faster. That work is now up to its 21st version as it works toward hopefully making it to the mainline kernel in the not too distant future...
