Linux Mint has released a beta of its next long-term-support (LTS) release, Linux Mint 22 (code-named "Wilma"), based on Ubuntu 24.04. Aside from the standard software updates that come with any major upgrade, some of Wilma's largest selling points are what it doesn't have; namely snap packages or GNOME applications that have broken theming on non-GNOME desktops like Mint's Cinnamon desktop.
sched_ext is a Linux kernel feature which enables implementing host-wide, safe kernel thread schedulers in BPF, and dynamically loading them at runtime. sched_ext enables safe and rapid iterations of scheduler implementations, thus radically widening the scope of scheduling strategies that can be experimented with and deployed, even in massive and complex production environments.
sched_ext was first sent to the upstream list as an RFC patch set back in November 2022. Since then, the project has evolved a great deal, both technically, as well as in the significant growth of the community of sched_ext users and contributors.
This MC is the space for the community to discuss the developments of sched_ext, its impact on the community, and to outline future strategies aimed at integrating this feature into the Linux kernel and mainstream Linux distributions.
Ideas of topics to be discussed include (but are not limited to):
While we anticipate having a schedule with existing talk proposals at the MC, we invite you to submit proposals for any topic(s) you’d like to discuss. Time permitting, we are happy to readjust the schedule for additional topics that are of relevance to the sched_ext community.
Submissions are made via LPC submission system, selecting the track Sched-Ext: The BPF extensible scheduler class.
We will consider the submissions until July 12th.
Since the disagreements that led to Eelco Dolstra stepping down from the NixOS Foundation board, there have been a number of projects forked from or inspired by Nix that have stepped up to compete with it. Two months on, some of these projects are now well-established enough to look at what they have to offer and how they compare to each other. Overall, users have a number of good options to choose from, whether they're seeking a compatible replacement for Nix (the configuration language and package manager) or NixOS (the Linux distribution), or something that takes the same ideas in a different direction.
Version 0.101 of Game of Trees has been released (and the port updated).
* got 0.101; 2024-07-11 see git repository history for per-change authorship informationDespite more novice developers being attracted by Rust to the kernel community, we have found their commits are mainly for constructing Rust-relevant toolchains as well as Rust crates alone; they do not, however, take part in kernel code development. By contrast, 5 out of 6 investigated drivers (as seen in Table 5) are mainly contributed by authors from the Linux community. This implies a disconnection be- tween the young and the seasoned developers, and that the bar of kernel programming is not lowered by Rust language.
As a bonus, it includes a ChatGPT analysis of LWN and Hacker News comments.
