  • Linux 4.14 Ensures The "Core Performance Boost" Bit Gets Set For AMD Ryzen CPUs

    Recently making waves in our forums was talk of a kernel patch to address a case where the AMD CPB (Core Performance Boost) isn't being exposed by Ryzen processors. Here's more details on that and some benchmarks.

    Being talked about recently is f7f3dc0: "CPUID Fn8000_0007_EDX[CPB] is wrongly 0 on models up to B1. But they do support CPB (AMD's Core Performance Boosting cpufreq CPU feature), so fix that."

  • Linus Torvalds Is Confident That Linux Kernel 4.14 LTS Will Arrive on November 5

    Development of Linux 4.14, the next LTS (Long Term Support) kernel series, continues with the fifth RC (Release Candidate) milestone, which was announced by Linus Torvalds himself this past weekend.

    According to Linus Torvalds, things have finally starting to calm down for the development of the Linux 4.14 LTS kernel, and it looks like the RC5 snapshot is smaller than he would have expected, at least smaller than last week's RC4, which is a good thing, meaning that there won't be need for eight RCs during this cycle.

  • Etnaviv Gallium3D Is Almost To OpenGL 2.0 Compliance

    The Etnaviv Gallium3D driver that provides reverse-engineered, open-source graphics support for Vivante graphics hardware is almost to exposing OpenGL 2.0.

    Etnaviv contributor Christian Gmeiner today posted a set of patches for adding occlusion queries support to the driver. The code at just over one thousand lines of code is the last major feature needed for exposing desktop OpenGL 2.0 capabilities with this community-driven driver.

  • AMD Developers Begin Making Open-Source FreeSync/AdaptiveSync Plans

    While the AMDGPU DC code is expected to land for Linux 4.15 with goodies like Vega display support, HDMI/DP audio, and atomic mode-setting, one of the sought after display features won't be initially supported: FreeSync or the VESA-backed AdaptiveSync.

    As we've known for a while, while AMDGPU DC fills out the requirements for being able to support FreeSync, the last bits of the implementation are not present as the interfaces are basically yet to be decided among the open-source driver developers. While AMD can post their existing FreeSync code as found in AMDGPU-PRO hybrid driver, they are trying to come up with a more standardized interface that will satisfy the other upstream Linux driver developers too that might want to support AdaptiveSync.

World’s smallest i.MX6 module tapped for customizable Linux SBC

Linux

Gumstix has added NXP’s tiny, Linux-driven SCM-i.MX6 module to its Geppetto design library, and has launched a “Cobalt MC” SBC to showcase the tiny COM.

Gumstix continues to add more computer-on-modules and single board computers to its Geppetto D2O design library, offering more options for developers to build custom board designs online for prototyping and quick manufacture of small runs. The latest addition, following its support for the Raspberry Pi and Pi Compute Module via its Gumstix Pi boards, is support for NXP’s tiny dual-core i.MX6 based SCM-i.MX6D COM, as well as for a similar quad-core SCM-i.MX6Q.

Image Processing on Linux

Filed under
Linux

I've covered several scientific packages in this space that generate nice graphical representations of your data and work, but I've not gone in the other direction much. So in this article, I cover a popular image processing package called ImageJ. Specifically, I am looking at Fiji, an instance of ImageJ bundled with a set of plugins that are useful for scientific image processing.

The name Fiji is a recursive acronym, much like GNU. It stands for "Fiji Is Just ImageJ". ImageJ is a useful tool for analyzing images in scientific research—for example, you may use it for classifying tree types in a landscape from aerial photography. ImageJ can do that type categorization. It's built with a plugin architecture, and a very extensive collection of plugins is available to increase the available functionality.

How to use an Arduino and Raspberry Pi to turn a fiber optic neural network into wall art

Linux
HowTos

Hollywood has made many big promises about artificial intelligence (AI): how it will destroy us, how it will save us, and how it will pass us butter. One of the less memorable promises is how cool it will look.

There's a great example of amazing AI visualization in Avengers: Age of Ultron when Tony Stark's AI butler Jarvis interacts with Ultron and we see an organic floating network of light morphing and pulsing. I wanted to make something similar to fill blank space on my apartment wall (to improve upon the usual Ikea art). Obviously, I couldn't create anything as amazing as Jarvis as a floating orb of light; however, I could use a machine learning algorithm that looks interesting with quirky data visualization: a neural network! It employs biologically inspired elements that were meant to replicate how (we thought) the human brain works.

  • Linux Users Discuss DRM – Unleaded Hangout

    Today my Patreons and I discuss encrypted media extensions, digital rights management and our freedom on the Linux desktop.

  • The European Parliament Should Be Talking About DRM, Right Now!

    [Teresa Nobre, Communia Association, Link (CC-0)] The European Union is currently discussing a reform of its copyright system, including making mandatory certain copyright exceptions, in order to introduce a balance into the system. However, no one, except Julia Reda, is paying any attention to one of the biggest obstacles to the enforcement of copyright exceptions in the digital age: technological protection measures (TPM), including digital rights management (DRM). In this blogpost we will present the reasons why the European Parliament should not lose this opportunity to discuss a reform of the EU anti-circumvention rules.

Servers and Red Hat: Cloud Foundry, Docker, CRI-O 1.0, Alibaba and Elasticsearch

  • How to deploy multi-cloud serverless and Cloud Foundry APIs at scale
    Ken Parmelee, who leads the API gateway for IBM and Big Blue’s open source projects, has a few ideas about open-source methods for “attacking” the API and how to create micro-services and make them scale. “Micro-services and APIs are products and we need to be thinking about them that way,” Parmelee says. “As you start to put them up people rely on them as part of their business. That’s a key aspect of what you’re doing in this space.”
  • Docker Opens Up to Support Kubernetes Container Orchestration
    There's been a lot of adoption of Kubernetes in the last few years, and as of Oct. 17 the open-source container orchestration technology has one more supporter. Docker Inc. announced at its DockerCon EU conference here that it is expanding its Docker platform to support Kubernetes. Docker had been directly competing against Kubernetes with its Swarm container orchestration system since 2015. The plan now is to provide a seamless platform that supports a heterogenous deployment that can include both Swarm and Kubernetes clusters. "Docker adapts to you because it's open," Docker founder Solomon Hykes said during his keynote address at DockerCon.
  • Introducing CRI-O 1.0
    Last year, the Kubernetes project introduced its Container Runtime Interface (CRI) -- a plugin interface that gives kubelet (a cluster node agent used to create pods and start containers) the ability to use different OCI-compliant container runtimes, without needing to recompile Kubernetes. Building on that work, the CRI-O project (originally known as OCID) is ready to provide a lightweight runtime for Kubernetes.
  • Red Hat brings its open source solutions to Alibaba Cloud

  • GNOME Mutter 3.27.1 Brings Hybrid GPU Support
    Mutter 3.27.1 has just been released as the first development release for the GNOME 3.28 cycle of this compositor / window manager. The change most interesting to us about Mutter 3.27.1 is support for hybrid GPU systems. The context for the hybrid GPU system support is explained via this bug report, "supporting systems with multiple GPUs connected to their own connectors. A common configuration is laptops with an integrated Intel GPU connected to the panel, and a dedicated Nvidia/AMD GPU connected to the HDMI ports."
