MGLRU v15 Published For Last Minute Testing Of This Major Linux Improvement
Google engineer Yu Zhao this morning published MGLRU v15, the latest revision to this patch series dealing with improving the Linux kernel's page reclamation code. Multi-Gen LRU "MGLRU" has proven to offer performance benefits and particularly improve the Linux experience when dealing with low-memory situations...
GStreamer Now Able To Ship Rust-Written Plugins
Along with the Linux kernel preparing for its initial Rust integration, Rusticl landing in Mesa this week as the first major Rust usage within Mesa, and Cloudflare announcing an Nginx HTTP proxy replacement written in Rust, some additional Rust adoption news for the week is that the GStreamer project is now ready to ship Rust-written plug-ins as part of their official binary releases...
Google Engineers Argue For Linux "ASI" To Better Deal With Speculative Execution Attacks
Proposed a few years ago was Kernel Address Space Isolation (KASI / ASI) for limiting data leaks with the growing number of speculative execution attacks on CPUs. Several organizations have been involved with Address Space Isolation efforts for the Linux kernel including IBM, Oracle, and Google with various approaches. Google engineers earlier this year posted a newer iteration of ASI focused on KVM use for the cloud / VMs. ASI still hasn't made it to the mainline kernel but Google engineers this week at LPC argued that it should be be the path forward for mainline in better dealing with these CPU security vulnerabilities...
Linux's Load Balancer Still Needs To Be Better Adapted For Intel Hybrid CPUs
Over the past year since launching Intel Alder Lake processors, Intel engineers have made a number of improvements to the Linux kernel for better dealing with the hybrid processor approach mixing P and E cores. While Alder Lake is running great with recent kernels and the P vs. E core selection for tasks on Linux is better than it was at launch, there still are areas for improvement as raised by Intel engineers this week...

With this latest patch series, he indicates he hopes to soon get this code mainlined...
Linux's Display Brightness/Backlight Interface Is Finally Being Overhauled
Hans de Goede of Red Hat has been involved with many great Linux desktop/laptop hardware improvements over the years for work that would have otherwise likely gone unaddressed. One of the initiatives he has been focusing on recently that has long been a sore point for Linux laptops has been the user-space backlight/brightness interface. This week at Linux Plumbers Conference was a presentation on this effort that has long been ripe for improvement...
