Linux 5.15-rc6

So here we are, slightly later on a Sunday than usual due to travel,
but rc6 is out.

I'd love to say that it's all looking average, but rc6 is actually
bigger han rc5 was, and larger than normal for this time in the
release cycle.

It's not _enormously_ larger than normal, and it's not the largest rc6
we've had, but it's still slightly worrisome. By rc6 I really do
expect things to have started calming down.

I'm hoping it's just one of those random timing effects, with a couple
of slightly bigger pulls having come in the last week, and we'll see
the next week being extra quiet because rc6 got some of the stuff that
would normally have hit rc7. It happens. But let's see how this goes.

The 5.15 cycle over-all remains one of the smaller cycles (at least
counting commits), so I wouldn't have expected this to be one that
requires an extra rc, but that may be what ends up happening unless
the upcoming week is really nice and calm.

That said, nothing in here looks _particularly_ worrisome. It really
smells like just random timing effects to me, with networking, GPU
drivers, and ntfs3 all having had a somewhat active week.  Other than
that it all really looks fairly normal.

Full details in the shortlog below.

Please give it a whirl. And let's hope for a nice calm next week and a
smaller rc7.

  • Linux 5.15-rc6 Ticks Up In Size, Stops Using AMD SME By Default - Phoronix

    We'll see how this week plays out to see if it will be worrisome or not the rest of the cycle. The brief 5.15-rc6 announcement can be read on the kernel mailing list.

    This past week saw mostly the wide assortment of fixes as usual for this stage of development. One somewhat notable change that landed this weekend is AMD SME no longer defaulting to being used on capable machines but rather needing to opt-in to that memory encryption feature. This was done to some buggy platforms that would otherwise experience boot problems with SME.

    The 5.15-rc6 kernel prepatch is out. "I'd love to say that it's all looking average, but rc6 is actually bigger than rc5 was, and larger than normal for this time in the release cycle. It's not _enormously_ larger than normal, and it's not the largest rc6 we've had, but it's still slightly worrisome."

Kernel: Slowdown, CephFS, and FS-Cache / CacheFiles

  • How a performance boost in Linux kernel for one family of Intel chips slowed its latest Alder Lake processors

    The mixture of performance and efficiency CPUs in Intel’s 12th-gen Core processors, code-named Alder Lake, hasn’t just been causing problems for some Windows gamers – it almost led to complications for Linux. Phoronix’s Michael Larabel noticed a performance hit in the kernel a fortnight ago – in a work-in-progress release candidate, we should stress – and a fix for the scheduling code landed a little later. It turned out the kernel suffered on Alder Lake chips due to a performance-enhancing tweak for another Intel processor family: the multiple-Atom-core-based Jacobsville. This year, Intel officially canned its Lakefield chips. These consisted of a performance core called Sunny Cove as well as Atom-class efficiency cores dubbed Tremont. Crucially, there are still multi-Tremont-core embedded processors out there, such as Snow Ridge. These are server and infrastructure-oriented components with up to 24 cores. The first proposed cut of kernel 5.16, specifically 5.16-rc1, contained a revision to the scheduler that makes it aware that some clusters of cores share a block of L2 cache – as seen in Snow Ridge and Jacobsville.

  • Testing the Linux Kernel CephFS Client with xfstests

    I do a lot of testing with the kernel cephfs client these days, and have had a number of people ask about how I test it. For now, I’ll gloss over the cluster setup since there are other tutorials for that.

  • Major Rewrite Of Linux's FS-Cache / CacheFiles So It's Smaller & Simpler - Phoronix

    As part of David Howells of Red Hat long-term work on improving the caching code used by network file-systems, he today posted a big patch series rewriting the fscache and cachefiles code as the latest significant step on that adventure. Howells posted a set of 64 patches for rewriting the kernel's fscache and cachefiles code. Linux's fsache is a general purpose cache used by network file-systems while cachefiles is for providing a caching back-end for mounted local file-systems. The Red Hat engineer has been working on this rewrite for more than the past year.

    Having the right speaker enclosure can make a big difference to sound quality, so it’s no surprise that customizable ones are a common project for those who treat sound seriously. In that vein, [zx82net]’s Universal Speaker Box aims to give one everything they need to craft the perfect enclosure.

  • The Calculator Charm: Calculatorium Leviosa! | Hackaday

    Have you ever tried waving your hand around like a magic wand and summoning a calculator? We would guess not since you’d probably look a little silly doing so. That is unless you had [Andrei’s] cool gesture-controlled calculator. [Andrei] thought it would be helpful to use a calculator in his research lab without having to take his gloves off and the results are pretty cool. His hardware consists of a PocketBeagle, an OLED, and an MPU6050 inertial measurement unit for capturing his hand motions using an accelerometer and gyroscope. The hardware is pretty straightforward, so the beauty of this project lies in its machine learning implementation.
