Last month it was noted on Phoronix that Canonical's kernel team is looking at folding their low-latency kernel optimizations into their generic kernel builds. Right now Ubuntu maintains a separate "lowlatency" kernel flavor with Kconfig tweaks in the name of low-latency responsiveness as an alternative to their "generic" kernel default, but for Ubuntu 24.04 LTS it continues looking like they'll move forward with this change of incorporating the changes into their default kernel build...

While there are a lot of Wayland compositors out there that aren't too different from each other in terms of features, one of the more unique ones is Greenfield. The Greenfield Wayland compositor has been out there for a few years now as an in-browser HTML5-based solution that is continuing to prove itself capable and even fast enough for handling Linux gaming...

Stemming from work done at Amazon Web Services (AWS) for better handling hypervisor live updates, a "request for comments" patch series was sent out on the Linux kernel mailing list for Pkernfs. The Pkernfs proposal was first detailed publicly by AWS last year and is for persisting guest memory and kernel/device state safely across Kexec...

When it comes to making use of the Rust programming language within the Linux kernel, one of the areas where it makes a lot of sense is for the video codec drivers given the amount of unknown/untrusted data submitted by user-space for video processing and it being a wide attack surface for bad actors. With the memory safety features of Rust this can be a big benefit to such drivers and Collabora is currently experimenting with a virtual codec driver Rust implementation to prove the concept...
