Jacob Adams wanders into
the kernel’s hibernation code:

How does Linux move from an awake machine to a hibernating one? How
does it then manage to restore all state? These questions led me to
read way too much C in trying to figure out how this particular
hardware/software boundary is navigated.

Linus has released 6.11-rc7 for testing.

And I wish I could say that things have calmed down, but I can’t
really say that. In fact, rc7 is slightly bigger than both rc6 and
rc5 were, both in number of commits, and in actual diff
size. That’s not really how it should work out.

That said, there’s nothing *scary* in here.

He is apparently “still waffling” about whether to release 6.11 next
weekend, which would cause the 6.12 merge window to land on top of the
Maintainers Summit, Linux Plumbers Conference, and Open Source Summit.

Alejandro Colomar, who has been maintaining the Linux man pages for the
last four years, has announced
that he will have to stop that work.

I’ve been doing it in my free time, and no company has sponsored
that work at all. At the moment, I cannot sustain this work
economically any more, and will temporarily and indefinitely stop
working on this project. If any company has interests in the
future of the project, I’d welcome an offer to sponsor my work
here; if so, please let me know.

Work on realtime preemption for the Linux kernel got its start almost exactly 20 years ago
(though it had its roots in earlier work, of course). It is fair to say
that finishing that job has taken a bit longer than anybody involved would
have expected. Now, though, Sebastian Andrzej Siewior has posted a brief
patch series making it possible to enable realtime preemption in the
mainline kernel on three architectures.

With the printk bits merged, PREEMPT_RT could be enabled on X86,
ARM64 and Risc-V. These three architectures merged required changes
over the years leaving me in a position where I have no essential
changes in the queue that would affect them.

Congratulations are due to the many developers who have worked on this
project for the last two decades.

The call for candidates
has gone out for the 2024 election of members of the Linux Foundation
Technical Advisory Board:

The TAB exists to provide advice from the kernel community to the
Linux Foundation and holds a seat on the LF’s board of directors;
it also serves to facilitate interactions both within the community
and with outside entities. Over the last year, the TAB has
overseen the organization of the Linux Plumbers Conference, advised
on the setup of the kernel CVE numbering authority, worked behind
the scenes to help resolve a number of contentious community
discussions, worked with the Linux Foundation on community
conference planning, and more.

Nominations are due by September 20.

Much of the early Rust code for the kernel has taken the form of
reimplementations of existing drivers as a proof of concept. One project,
though, is entirely new: the driver for Apple GPUs written by Asahi Lina.
This driver has shipped with Asahi
Linux for some time and, by many accounts, is stable, usable, and a
shining example of how Rust can be used in a complex kernel subsystem.
That driver remains outside of the mainline kernel, though, and merging
currently looks like a distant prospect. The reasons for that state of
affairs highlight some of the difficulties inherent in integrating a new
language (and its associated development style) into the Linux kernel.

Linus has released 6.11-rc6 for testing.
“Things look pretty normal, although we have perhaps unusually many
filesystem fixes here, spread out over smb, xfs, bcachefs and netfs.“

Here is a piece of advice for anybody wanting an easy and frustration-free
life: do not run your own email system. While there numerous advantages to
keeping some control over your communications, there is also a long list of
things that can go wrong. A recent failure of spam filtering on the LWN
email system illustrated one of those ways, as well as shining a light on
how even a seemingly independent email system is tied to other services
across the net.

Back in 2021, the ElasticSearch search engine and Kibana visualization
platform were relicensed under the non-free
Server Side Public License (SSPL). Now, Elastic (the company owning those
projects) has announced
that those projects will also be distributable under the Affero GPL license.

We never stopped believing and behaving like an open source
community after we changed the license. But being able to use the
term Open Source, by using AGPL, an OSI approved license, removes
any questions, or fud, people might have.

Dave Airlie makes
an analogy between the stages of road building and those of adding Rust
to the Linux kernel.

For the wayfinders the process of interacting with maintainers is
frustrating and slow, and they don’t enjoy it as much as
wayfinding, and because they still only care about the hotel at the
end, when a maintainer gets into the details of their particular
intersection they don’t want to do anything but go stay in their
hotel.

The road will get built, it will get traffic on it. There will be
tunnels where we should have intersections, there will be bridges
that need to be built from both sides, but I do think it will get
built.

The venerable AnandTech site has announced
its closing after 27 years of technology-industry coverage.

Still, few things last forever, and the market for written tech
journalism is not what it once was – nor will it ever be again. So,
the time has come for AnandTech to wrap up its work, and let the
next generation of tech journalists take their place within the
zeitgeist.

The site will surely be missed.

Wedson Almeida Filho, one of the key developers driving the Rust for Linux project, has retired from the
project.

After almost 4 years, I find myself lacking the energy and
enthusiasm I once had to respond to some of the nontechnical
nonsense, so it’s best to leave it up to those who still have it
in them.

As an example of the sort of “nonsense” he referred to, he provided a link to the video from the
Rust for filesystems discussion at the 2024
Linux Storage, Filesystem, Memory-Management, and BPF Summit. His work was
fundamental to getting the project as far as it has come; he will be missed.

The Mono project was started in 2001 to develop a .NET environment for
Linux systems. Microsoft has owned that project since 2016, but has not
made a major release since 2019. The company has now announced that Mono is being
handed over to the WineHQ organization, which will maintain the repository going
forward. Microsoft, meanwhile, is steering users toward its “modern
fork” that it continues to maintain.
