Linux 4.17 RC 1

Filed under
Linux
  • Kernel prepatch 4.17-rc1

    Linus has released 4.17-rc1 and closed the merge window for this release.

  • Linux 4.17-rc1
  • Linux 4.17-rc1

    So two weeks have passed, and the merge window was pretty normal and
    is now closed.

    This does not seem to be shaping up to be a particularly big release,
    and there seems to be nothing particularly special about it. The most
    special thing that happened is purely numerology: we've passed the six
    million git objects mark, and that is reason enough to call the next
    kernel 5.0. Except I probably won't, because I don't want to be too
    predictable. The version numbers are meaningless, which should mean
    that they don't even follow silly numerological rules - even if v3.0
    and v4.0 happened to be at the 2M and 4M mark respectively.

    But v5.0 will happen some day. And it should be meaningless. You have
    been warned.

    Anyway, we do have a *few* other things that happened, like Arnd
    getting rid of a number of architectures that seem to simply not
    matter any more. If it turns out that somebody wants to resurrect any
    of them, the code is all there in the git history, but you'll have to
    do the work and show that you'll maintain it and have a few users.

    And just to not make it *all* about removing old architectures,
    there's a new one in there too.

    The architectures that are gone are blackfin, cris, frv, m32r, metag,
    mn10300, score, and tile. And the new architecture is the nds32
    (Andes Technology 32-0bit RISC architecture).

    We actually have a fair amount of other removal and cleanups too. I
    was somewhat pleasantly surprised by the number of pull requests that
    actually ended up removing a lot of lines. Some of it was staging
    drivers that finally gave up the ghost (like irda), but we also got
    rid of some copyright language boiler-plate in favor of just the spdx
    lines. And some pre-shipped lexer/parser files are no more, we're
    better off just generating them.

    End result: we actually removed more lines than we added:

    13538 files changed, 627723 insertions(+), 818855 deletions(-)

    which is probably a first. Ever. In the history of the universe. Or at
    least kernel releases.

    I'd call it momentous, but I think the arch removal was most of it,
    and I'm sure people will quickly rectify that momentary glitch of
    actually shrinking the kernel source code.

    Go out and test,

    Linus

  • Linux 4.17-rc1 Kernel Released: A Ton Of New Functionality While Shedding Old Code

    Just like clockwork the Linux 4.17-rc1 kernel was released tonight following the two week long merge window.

    See the Linux 4.17 features article published this morning to learn all about what's new in this kernel release. There is a ton of work from prominent AMD and Intel graphics driver updates to new hardware support and much more. As covered just a short time ago, Linux 4.17 power measurements are looking surprisingly good for lowering the power use while idling and also the power efficiency under load.

    More Linux 4.17 kernel benchmarks are on the way.

  • Linux 4.17 Offers Some Promising Power-Savings Improvements

    Of the many improvements to be found in the in-development Linux 4.17 kernel -- nicely summarized in our Linux 4.17 feature overview -- one of the features I've been anxious the most to begin benchmarking has been the reported power management improvements. Here are my initial power/performance tests of Linux 4.17 that for some systems is seeing a measurable drop in power usage, even in some cases under load while without sacrificing the performance.

  • The Many Great Features & Changes Coming For The Linux 4.17 Kernel

    Linus Torvalds is expected by the end of the day to release Linux 4.17-rc1, thereby marking the end of the two-week merge window that saw a lot of changes and new features land for Linux 4.17. Here is our original feature overview of the changes to be found in this next major release of the Linux kernel, which should premiere as stable by the middle of June.

    While many of you have likely not even upgraded yet to the feature-packed Linux 4.16, there is a lot more coming to look forward to with the Linux 4.17 kernel this summer. There are many Intel/AMD graphics driver improvements, support for obsolete CPU architectures being dropped, some new CPU support added including initial bits for the NVIDIA Xavier SoC, a potentially very big improvement for dropping Linux idle power usage, various file-system improvements, new hardware support, and even improvements for the Macintosh PowerBook 100 series from more than 20 years ago.

Linus Torvalds schedules Linux Kernel 5.0

  • Linus Torvalds schedules Linux Kernel 5.0, then maybe delays 'meaningless' release

    Linus Torvalds has suggested that the next Linux kernel could earn the number “5.0”.

    Torvalds’ suggestion came in his announcement of the first release candidate for version 4.17, which he said “does not seem to be shaping up to be a particularly big release, and there seems to be nothing particularly special about it.”

    Unless you count the fact it is shrinking, which Torvalds liked because by removing support for eight architectures, and a bunch of other “removal and clean-ups … we actually removed more lines than we added.”

    Torvalds declared the reduction “probably a first. Ever. In the history of the universe. Or at least kernel releases.”

    He also said the “most special thing that happened” in 4.17 rc1 was “purely numerology: we've passed the six million git objects mark, and that is reason enough to call the next kernel 5.0.”

  • Compact Bay Trail SBC has option for third GbE port
    Axiomtek’s “CAPA84E” is a 3.5-inch Bay Trail SBC with an optional third GbE port, dual M.2 slots, plus VGA, DisplayPort, USB 3.0, SATA, and -20 to 70°C support. Axiomtek’s motto may well be: “If first you succeed, iterate until you don’t.” The king of the spinoffs has released yet another iteration of one of the first Intel Bay Trail SBCs, the CAPA841, which in 2015 was followed by the slightly scaled down CAPA840. The new CAPA84R similarly supports Bay Trail and conforms to the 3.5-inch form factor, but with a different mix of features.

  • Cities agree on minimal interoperability mechanisms

    Over a hundred European cities have agreed on ‘Minimal Interoperability Mechanisms’ defining the communication between software programmes and building blocks to allow co-creation and sharing of services. The MIMs, advocated by the Open & Agile Smart Cities (OASC) initiative, are “simple steps towards using new technology”, OACS chairman Martin Brynskov said on Thursday.

  • Containers On The Edge
    There are two major families for the choice of operating system and ecosystem: RTOS-based and Linux-based families. Smaller, cost-constrained devices tend to benefit from the simplicity of RTOS-based, while more full-featured and complex devices benefit from the richness of Linux (see The Shift to Linux Operating Systems for IoT for more background on the reasons for these approaches in IoT). Linux has been used in embedded devices for almost as long as it has existed (see here for an excellent timeline of early embedded Linux usage by Chris Simmons). The focus here is on Linux based products, as they have the needed functions such as access controls and memory segregation that allows for upgrading portions in a controlled fashion.
  • YouTuber Fits A Fully Functional Computer Into A Mouse
    While the YouTuber’s original plan was to squeeze a Raspberry Pi inside of a regular computer mouse but was unable to do so due to size constraints. Hence, he 3D printed a computer mouse to fit the components of the computer inside the mouse. Dubbed as “The Computer Mouse”, the device consists of a Raspberry Pi Zero W computer, a 1.5-inch color OLED LCD display with a resolution of 128 x 128 pixels, a 3D-printed mouse, a rechargeable 500 mAh battery, and a tiny Bluetooth retractable keyboard for text inputs and more complicated commands. It also has a power button at the edge to start the tiny computer. Further, it runs GNU/Linux-based operating systems such as Raspbian.

Microsoft Wallet is the official tap-to-pay method for Windows Phones, similar to Apple Pay and Google Pay on iPhones and Android devices. The app also allows users to load up their loyalty and membership cards, allowing them all to be stored in one place.
