[$] Smarter IRQ suspension in the networking stack

7 hónap óta
High-performance networking is a highly tuned activity; the amount of time available to deal with each packet may be measured in nanoseconds, so care must be taken to avoid anything that might slow the process down. Recently, there has been a fair amount of attention given to a patch set merged for 6.13 that, it is claimed, can improve processing efficiency (and, thus, power savings) in data centers by as much as 30%. The change itself, contributed by Joe Damato and Martin Karsten, is a relatively small tweak to existing optimization techniques; it shows just how much care is needed to optimize a high-bandwidth server.

[$] Maintainer opinions on Rust-for-Linux

7 hónap óta

Miguel Ojeda gave a keynote at FOSDEM 2025 about the history of the Rust-for-Linux project, and the current attitude of people in the kernel community toward the experiment. Unlike his usual talks, this talk didn't focus so much on the current state of the project, but rather on discussing history and predictions for the future. He ended up presenting quotes from more than 30 people involved in kernel development about what they thought of the project and expected going forward.

A Rust-for-Linux policy document

7 hónap óta
Miguel Ojeda has announced the posting of a new document describing policies around the use of Rust in the Linux kernel.

There has been a fair amount of confusion about what the kernel policies around Rust are, who maintains what and so on. This document tries to clarify some of these points with what, to the best of our knowledge, is the current status.
