Linux 5.15-rc1

Filed under

So 5.15 isn't shaping up to be a particularly large release, at least
in number of commits. At only just over 10k non-merge commits, this is
in fact the smallest rc1 we have had in the 5.x series. We're usually
hovering in the 12-14k commit range.

That said, counting commits isn't necessarily the best measure, and
that might be particularly true this time around. We have a few new
subsystems, with NTFSv3 and ksmbd standing out. And as a result, when
you look at the stats on a "lines changed" basis, 5.15-rc1 ends up
looking much more middle-of-the-road. It still doesn't look like a
particularly _big_ merge window, but also not remotely the smallest

And while this is not up there with some larger releases, it's
actually been one of the messier merge windows. Part of it was
self-inflicted damage from me trying to enable -Werror much more
aggressively, but I also ended up having to push back a lot more on
some of the patch series and had a number o full requests where I went
"ok, I've pulled this, but XYZ is wrong".

So we've had merge windows that went much more smoothly. In fact, I
have a pull request or two that I just didn't feel like going through
fully, and I might still pull the upcoming week, but I got a bit fed
up with how I ended up seeing new pull requests - and not for fixes -
coming in fairly late in the merge window. Yes, the merge window is
two weeks, but part of that is very literally to give _me_ time to
actually look things through, not for people to send me new requests
up until the very end of the merge window.

Anyway, I'm hoping that things calm down, and I'll take a look at a
few things still in my inbox, but on the whole you should expect that
"that's it" and send me fixes only.

And in order to get those fixes going, please go out and test this.

Appended, as always, is my "mergelog" - since even at "only" 10k+
commits, the shortlog is not really realistically readable or useful
as a summary. And as always, the mergelog credits the person I pulled
from, which is not the same as the actual author of all the changes.
There's just over a hundred people listed below that I've pulled from,
but over 1500 people with authorship credit in the git tree. So that's
where you'd need to dig for all the details.

  • Linux 5.15-rc1 Brings New NTFS Driver, In-Kernel SMB3 Server, AMD Changes, Intel DG2

    As expected this evening the Linux 5.15-rc1 kernel was released to top off the two week merge window that saw many changes to the kernel.

    Tomorrow I'll have published our extensive feature overview of Linux 5.15 changes, but some of the highlights include Paragon NTFS3 as the new NTFS file-system driver, KSMBD as an in-kernel SMB3 file server, opt-in L1d cache flushing on context switching, continued Apple M1 bring-up work, many AMD improvements, and initial Intel DG2/Alchemist and XeHP discrete graphics bring-up work, among a lot of other new hardware enablement.

  • Linus Torvalds Announces First Linux 5.15 Kernel Release Candidate

    It's been two weeks since the release of Linux kernel 5.14, which slowly makes its way into the stable software repositories of various popular GNU/Linux distributions, and now it's time to go out and test another new kernel series, Linux 5.15, which will be released later this fall.

    Linux 5.15 looks to be yet another release that focuses on further improving the support for AMD CPUs and GPUs, but it will also bring new features like NTFS3 and KSMBD (CIFS/SMB3) support, and the usual new and updated drivers for better hardware support. But all in all, it looks like a small release.

  • Linus Torvalds admits to 'self-inflicted damage' with '-Werror' as Linux 5.15 rc1 debuts

    Linus Torvalds has loosed the first release candidate for version 5.15 of the Linux kernel, with but isn't sure if it's a big 'un or nothing to get excited about.

    "So 5.15 isn't shaping up to be a particularly large release, at least in number of commits. At only just over 10k non-merge commits, this is in fact the smallest rc1 we have had in the 5.x series," he wrote in his weekly missive on the state of kernel development. But he also wondered if measuring kernels by commits is valid and suggested measuring new kernel versions by the number of lines changed.

    On the latter measure, thanks to substantial new subsystems like NTFSv3 and KSMBD, Torvalds stated "5.15-rc1 ends up looking much more middle-of-the-road. It still doesn't look like a particularly _big_ merge window, but also not remotely the smallest one."

    Whatever the size of the new kernel, Torvalds rated it "one of the messier merge windows".

Intel Announces 12th Gen Core "Alder Lake" CPUs, Linux Tests Forthcoming

Intel is using their inaugural Intel Innovation virtual event today to formally announce the highly-anticipated 12th Gen Core "Alder Lake" processors. These first desktop processors built on their "Intel 7" process and employ a hybrid architecture will be available in retail channels next week. Today we can talk more about Alder Lake specifications and features while our Linux performance benchmarks and support analysis will come once the Alder Lake review embargo expires next week. While there have been many Alder Lake leaks in recent weeks/months and a number of features disclosed back during Architecture Day, today marks the official unveil for the next-gen Intel Core processors. This is a very exciting transition as they have now shifted to their Intel 7 manufacturing process, the hybrid architecture provides a combination of high performance and low power cores depending upon needs, and Intel is at the forefront now in delivering DDR5 memory and PCIe 5.0 to the masses. When it comes to performance, Intel claims Alder Lake can deliver up to two times the performance of prior generation processors for content creation workloads. Meanwhile when it comes to the generational performance uplift for the P (Performance) cores it's said to be around 19%. Read more

Murena smartphones and cloud will protect our privacy

More than ever the market is demanding a new approach for digital products: more and more people around the world want something different, more ethical, more sustainable, with real guarantees about personal data protection. Four years ago, I wanted to break free from Google and Apple, and therefore we created the “eelo” project, with the simple idea that a different mobile operating system and associated cloud services like email or cloud storage could be possible in this world. Followed by an amazing community of supporters, contributors and now users, the project progressed quickly, and became a reality by the end of 2018. The same year, we had to suddenly abandon our initial project name for a temporary name: /e/. Sometimes, temporary things last longer than expected. And despite being hard to pronounce, difficult to search, and largely criticized by many people, /e/ as a brand name had the benefit to be very singular and helped us appear different. In the end it conveyed the idea that we’re doing something special. […] Nevertheless, as we are reaching more and more people and progressively catching interested from a mainstream audience, we have to introduce a new, strong brand, easier to use, easier to refer to and easier to share with people. The goal of this brand is to have a strong name to call our products, intended to be used by a large number of users in many different countries and cultures. It took some time, since we had many different candidates, both from internal suggestions and from our community. We wanted something that would both convey our project’s values, and that could be within the same lineage of our initial project name. We also had to secure this new brand making sure it was not already in use in the same field of activity, and by entering a long trademark registration processes. Read more
