[$] Highlights from systemd v258: part one

The next release of systemd has been percolating for an unusually
long time. Systemd releases are usually about six months apart, but
v257 came out in
December 2024, and v258 just now seems to be nearing the finish
line; the third release candidate for v258 was published on
August 20 (release
notes
). Now is a good time to dig in and take a look at some of
the new features, enhancements, and removals coming soon to
systemd. These include new workload-management features, a concept for
multiple home-directory environments, and the final, once-and-for-all
removal of support for control
groups version 1

Cache-Aware Scheduling For Linux Refined – Better AMD & Intel CPU Performance

Going on for several months now has been an effort to wire up cache-aware scheduling / load balancing for the Linux kernel for helping out task placement for processors with multiple cache domains such as modern AMD Ryzen/EPYC and Intel Xeon platforms. This cache-aware scheduling has shown much potential for Linux with further enhancing performance on today’s interesting CPUs. Out today is the third iteration of cache-aware scheduling with an important rework…

Zed Editor Introduces Built-In Debugger

One of the long sought features for Zed has been having built-in debugger capabilities and that work has finally been merged to the project’s codebase…

[$] The hierarchical constant bandwidth server scheduler

The POSIX
realtime model
, which is implemented in the Linux kernel, can ensure
that a realtime process obtains the CPU time it needs to get its job done.
It can be less effective, though, when there are multiple realtime
processes competing for the available CPU resources. The hierarchical
constant bandwidth server
patch series, posted by Yuri Andriaccio with
work by Luca Abeni, Alessio Balsini, and Andrea Parri, is a modification to
the Linux scheduler intended to make it possible to configure systems with
multiple realtime tasks in a deterministic and correct manner.

Arch Linux Moving To WoW64 Wine & Wine-Staging

The Arch Linux project announced this week they are working to transition their Wine and Wine-Staging packages over to pure WoW64 builds. This “Windows on Windows 64-bit” allows for 32-bit Windows applications on 64-bit Linux platforms without needing 32-bit software libraries/prefixes present and overall a big architectural win…
