A Massive ARM v6/v7 Rework Is Landing With Linux 4.5 Plus Raspberry Pi 2 Support

Filed under
Hardware

Olof Johansson sent in all of the ARM SoC updates for the Linux 4.5 merge window on Friday night. Most significant is the ARM multi-platform code update. Olof explained, "This branch is the culmination of 5 years of effort to bring the ARMv6 and ARMv7 platforms together such that they can all be enabled and boot the same kernel. It has been a tremendous amount of cleanup and refactoring by a huge number of people, and creation of several new (and major) subsystems to better abstract out all the platform details in an appropriate manner. The bulk of this branch is a large patchset from Arnd that brings several of the more minor and older platforms we have closer to multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview Much of this is moving around header files from old mach directories, but there are also some cleanup patches of debug_ll (lowlevel debug per-platform options) and other parts."

  • Raspberry Picademy USA Accepting Applications

    Are you an enthusiastic individual that is interested in using the Raspberry Pi in the classroom and in community education programs? Then get ready to fill out your application for Raspberry Picademy USA! This will be the first time ever that the Raspberry Pi Foundation will be offering a Picademy in the United States. If you haven’t ever heard of Picademy, or have and are looking to participate, then I’ll answer some basic questions for you on the ins and outs of Raspberry Picademy USA.

  • Wintel Is Sick

    There isn’t any end in sight. As ARM and particularly ARM on mobile devices grows Wintel is being squeezed out of personal IT. Long ago, I and many others cut out That Other OS. Now many millions, billions even, are cutting out Intel. Both heads of the Wintel monopoly are diversifying as fast as they can and cutting prices or moving “profit centers” to avoid being trapped under the weight of their own handiwork. The world just doesn’t need either any longer but it does take a few years to switch over so much installed base of IT. It’s a process, not an event, just like sickness. It remains to be seen whether this is a mortal wounding or just an injury both can survive. I expect that both will survive but both will be cut down to size and only get a normal share of the pie instead of the whole thing.

  • Opportunities And Challenges That The Internet Of Things Creates

    Internet of Things is targeting not only devices, but also sensors. It’s incredible how they can be attached everywhere and record necessary data. For example, wearables are collecting data about fitness habits of their owners and this helps to update the devices with more attention paid to the functionality in high demand. Or, for example, network-connected sensors are used to inform farmers about the pregnancy and sickness of animals. Just imagine if your coffee cup could know how hot you want your coffee to be and how much sugar or milk you add. Collected data would allow businesses to get more specific information on how their products are used, how they break down and what is expected from them in the future.

  • Google, HP, Oracle Join RISC-V

    RISC-V is on the march as an open source alternative to ARM and Mips. Fifteen sponsors, including a handful of high tech giants, are queuing up to be the first members of its new trade group which will host next week its third workshop for the processor core.

    RISC V is the latest evolution of the original RISC core developed more than 25 years ago by Berkeley’s David Patterson and Stanford’s John Hennessey. In August 2014, Patterson and colleagues launched an open source effort around the core as an enabler for a new class of processors and SoCs with small teams and volumes that can’t afford licensed cores or get the attention of their vendors.

  • An Open Source Reference Architecture For Real-Time Stock Prediction

    While this post does not cover the details of stock analysis, it does propose a way to solve the hard problem of real-time data analysis at scale, using open source tools in a highly scalable and extensible reference architecture. The architecture below is focused on financial trading, but it also applies to real-time use cases across virtually every industry. More information on the architecture covered in this article is also available online via The Linux Foundation, Slideshare, YouTube, and Pivotal Open Source Hub, where the components in this architecture can be downloaded.

  • Open-Source Tessellation Lands For Pre-Broadwell Intel Hardware

    Back on Christmas was news of patches for implementing tessellation shader support for Intel Ivy Bridge and Haswell graphics hardware after support had already landed for Broadwell and newer within the Mesa driver. Support for those older generations is now present in Mesa.

    As of this afternoon, Kenneth Graunke's work for implementing GL_ARB_tessellation_shader support for Ivy Bridge and Haswell is now within Mesa Git master. This makes tessellation support implemented for all hardware capable of doing so -- Sandy Bridge and older are not.

Hardware

The Raspberry Pi was created as an educational platform but has become one of the most popular embedded systems platforms on earth with a full copy of Linux and a rabid community of DIY-minded developers. That combination alone makes the Raspberry Pi a natural fit for hacking together enterprise IT applications and devices. Add in its low cost and the ready availability of open source solutions, and you can quickly see how previously expensive systems and devices are suddenly within reach of IT departments willing to experiment with Raspberry Pi, as my first foray into DIY IT Raspberry Pi projects showed.

Windows 'Upgrade'

  • When A Computer Is Ready for the Junk Pile
    To that point, there was a report that a mail server failure in a large business office remained a mystery for two days until someone found an old Pentium II back in the corner of some obscure closet with a burned out power supply. It is reported that the Slackware/Debian/Red Hat machine had been plugging away as a mail server for a number of years, completely unattended. That’s feasible I suppose, but I further suppose that it’s a modern day parable about how open source can indeed, carry the day.
  • Microsoft draws flak for pushing Windows 10 on PC users
    With about a month left for many PC users to upgrade to Windows 10 at no charge, Microsoft is being criticized for its aggressive — some say too aggressive — campaign to get people to install the new operating system.
  • Microsoft forks out thousands over forced Windows 10 upgrade
    Microsoft has had to pay a Windows user in California US$10,000 over a forced upgrade to Windows 10, according to a report in the Seattle Times. The user, Teri Goldstein, runs a travel agency in Sausalito, a San Francisco Bay Area city in Marin County, California.
  • A lawsuit over an unwanted Windows 10 upgrade just cost Microsoft $10,000
    Microsoft recently paid a (very small) price for its Windows 10 upgrade tactics, and that was before they became increasingly aggressive.
  • Updategate: California woman awarded $10,000 for borked Windows 10 upgrade
    A CALIFORNIA woman has set a precedent after a court ruled that she was entitled to damages over the installation of Windows 10 on her machine. Teri Goldstein, a travel agent, testified that the new operating system had auto-downloaded, started to install, failed, and left her Windows 7 computer running painfully slowly and often unusable for days. "I had never heard of Windows 10," Goldstein told reporters. "Nobody ever asked me if I wanted to update."
  • Microsoft pays out $10,000 for automatic Windows 10 installation

  • 'I urge everyone to fight back' – woman wins $10k from Microsoft over Windows 10 misery
    A California woman has won $10,000 from Microsoft after a sneaky Windows 10 update wrecked the computer she used to run her business. Now she's urging everyone to follow suit and "fight back." Teri Goldstein – who manages a travel agency in Sausalito, just north of San Francisco – told The Register she landed the compensation by taking Microsoft to a small claims court. Rather than pursue a regular lawsuit, she chose the smaller court because it was better suited to sorting out consumer complaints. Crucially, it meant Microsoft couldn't send one of its top-gun lawyers – or any lawyer in fact: small claims courts are informal and attorneys are generally not allowed. Instead, Redmond-based Microsoft had to send a consumer complaints rep to argue its case.
