  • R9 Fury Performance Gains With Linux 4.5-rc2? I'm Not So Lucky

    When reading this morning of "double or quadruple the framerates that I got with RC1" for an R9 Fury owned by a Phoronix reader, I immediately set out to run some R9 Fury benchmarks on Linux 4.5-rc2 compared to my 4.5-rc1 results last week and compared to Catalyst. I also did the same for an R9 285 Tonga on AMDGPU as well for reference purposes.

  • AMDGPU ACP Support Called For Merging Still Into Linux 4.5

    While the Linux 4.5 kernel's merge window ended more than one week ago, it looks like the AMDGPU driver may get a late feature arrival: ACP support.

    ACP is the Audo Co-Processor support found in new AMD APUs/SoCs. AMD developers had been working on the support for several months while the audio and power management related ACP code landed during the Linux 4.5 merge window. With that code now mainlined, AMD's Alex Deucher is looking to land the ACP driver support into the AMDGPU DRM driver.

  • The Intel Mesa Driver Has Gotten Faster Since Switching To NIR

    Eduardo Lima of Igalia spoke this weekend at FOSDEM about the work done over the past year on switching the Mesa Intel i965 back-end to using the NIR intermediate representation.

    The presentation by this developer covered GLSL IR vs. NIR, the Intel shader pipeline, what NIR is all about, and more. NIR is the new Mesa intermediate representation that was initially designed by a high school student. Besides Intel's interest in NIR, Freedreno and VC4 Gallium3D drivers have also been actively interested in this IR.

  • 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.

  • 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
    The Amsterdam-based company behind Elasticsearch and Elastic Stack said the new offering would be available to Alibaba Cloud customers as an add-on, giving them access to real-time search, logging, and data analytics capabilities.

  • 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.
  • Cockpit 153
    Cockpit is the modern Linux admin interface. We release regularly. Here are the release notes from version 153.
  • 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."
