Filed under
Linux

The XFS changes targeting the Linux 3.20 kernel have been published, but this time around the file-system work isn't particularly exciting.

The changes queued by Dave Chinner for the XFS file-system in Linux 3.20 include...

PlayStation 3 Support Is Still Being Worked On Within The Linux Kernel

Filed under
Linux
Gaming

The PowerPC architecture updates for the Linux 3.20 kernel, including some improvements for the Sony PlayStation 3 game console.

While Sony long ago removed the "Other OS" functionality from the PlayStation 3, it seems some open-source developers are still working on the PS3 support for Linux.

Geoff Levand landed a few PS3 kernel patches for mainline Linux kernel integration via the 3.20 POWER pull request.

In terms of what these new PS3 patches allow, Geoff explained recently, "It will allow a kexec based bootloader (petitboot for example) to pre-allocate a highmem region and store things like an initrd or other large data needed to boot an OS. With some PS3 configurations the boot memory region is not large enough to fit all the boot data."

CoreOS and the App Container Spec

Filed under
Linux

The open-source Docker application virtualization container project has become a defacto standard for applications containers over the course of the last year. But it's a defacto standard that isn't a real specification and is one that is being challenged by Linux distribution vendor CoreOS.

TPM 2.0 Support Sent In For The Linux 3.20 Kernel

Filed under
Linux

Trusted Platform Module 2.0 (TPM 2.0) is to be supported by the Linux 3.20 kernel.

While many Linux users and free software advocates are opposed to TPM, TPM 2.0 is going to be supported by the next version of the mainline Linux kernel. Trusted Platform Module technology has already been supported by the mainline Linux kernel but TPM 2.0 breaks backward compatibility with TPM 1.2. TPM 2.0 supports many more alogirhtms, crypto primitives, root keys, and authorization differences. For those learning about TPM for the first time or are just unfamiliar with the differences to TPM 2.0, see the Wikipedia page for a basic overview and the Trusted Computing Group's TPM 2.0 FAQs.

The TPM 2.0 support for the Linux kernel is being pulled in through the security subsystem changes for the 3.20 kernel.

The Linux Setup - Matthew Miller, Fedora Project Leader

Red Hat
Interviews

I met Matthew at LinuxCon 2013 and have been hounding him for an interview ever since then. He’s worth the wait, though. He really gets under the hood of his GNOME setup and he has some great things to say about the power of open source software. Also, I’ve mentioned this before, but it’s worth repeating: Fedora has been great for me lately. I know there have always been Fedora fans, but my experience with it was always that there were one or two annoyingly broken things in each release. But 21 is solid. Like Ubuntu solid. And that’s thanks to the work of people like Matthew.

Linux and Graphics: AMD, Linux 4.14 LTS, Etnaviv Gallium3D

  • 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.

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
    Alibaba Cloud has joined the Red Hat Certified Cloud and Service Provider program, with Red Hat solutions to become directly available to Alibaba Cloud customers in the coming months.
  • Elasticsearch now on Alibaba Cloud, eyes China market

Software: VirtualBox 5.1.30, Cockpit 153, GNOME Mutter 3.27.1, KDE Neon

  • Oracle Releases VirtualBox 5.1.30 to Patch Glibc 2.26 Compile Bug on Linux Hosts
    Oracle released VirtualBox 5.1.30, a minor maintenance update to the open-source and cross-platform virtualization software that addresses a few important issues reported by users from previous versions. Coming one month after the VirtualBox 5.1.28 release, which probably most of you out there use right now on your personal computers, VirtualBox 5.1.30 contains a fix for a Glibc 2.26 compilation bug for Linux hosts and a 3D-related crash for Windows guest that use the Windows Additions package.

  • 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."
