  • Linux 5.2 To Allow P2P DMA Between Any Devices On AMD Zen Systems

    With the Linux 5.2 kernel an AMD-supplied change by AMDGPU developer Christian König allows for supporting peer-to-peer DMA between any devices on AMD Zen systems.

  • KVM Changes Make It Into Linux 5.2 With Improvements For x86, POWER, ARM

    The Kernel-based Virtual Machine (KVM) changes were sent out on Friday of the new feature updates for the Linux 5.2 kernel that is nearing the end of its merge window. 

    New KVM material for Linux 5.2 includes support for SVE and pointer authentication for guests on the ARM front along with PMU improvements. Over in the POWER space is now the ability to directly access the POWER9 XIVE interrupt controller and various memory and performance optimizations. Meanwhile on the x86 front is support for accessing memory not backed by a struct page along with other fixes and refactoring.

  • DRM Fixes Head Into Linux 5.2 While Letting Nouveau Turing TU117 Support Slip In

    Following last week's big feature update to the DRM graphics drivers, an initial batch of "fixes" has now been merged to the early Linux 5.2 development code for these Direct Rendering Manager drivers. 

    These include AMDGPU SR-IOV fixes, Radeon R500 PLL fixes for that old X1000 series hardware, various Intel graphics driver fixes, Nouveau Turing mode-setting fixes, and fixes to several of the smaller drivers.

  • A Push Towards Firmware-less Video Decoding By Linux Kernel Media Drivers

    Veteran Linux multimedia developer Paul Kocialkowski summed up the current situation this week of many hardware platforms having a general purpose micro-controller running a non-free firmware blob for coordinating the video decoding work. It makes it easier to program with this firmware-based approach but makes the driver less free and now with recent Linux infrastructure improvements could better support dealing with the video hardware itself. 

    While the firmware-based video decoding makes the driver work easier, it's contingent upon the binary firmware blobs and the micro-controller running it doesn't necessarily be wasting energy on that task. With recent work on the Linux kernel's media interface, the kernel can now better support interfacing with hardware decoders directly. 

  • Intel Agilex Now Supported By Linux 5.2 Kernel; ARM Boards Like Jetson Nano Also Added

    Olof Johansson sent in the SoC updates on Thursday for the Linux 5.2 kernel merge window that is nearing the end. There is new SoC support for this new kernel and a number of new boards also being supported. 

  • The Open-Source / Linux Highlights From OSTS 2019

    We've had a number of articles covering the interesting news out of Intel's 2019 Open-Source Technology Summit (OSTS) held at Skamania Lodge in Stevenson, Washington. Here's a look back at the news out of the open-source event as well as some other smaller bits of information shared during the event.

  • PRIME GPU Offloading Improvement For GLXVND Merged For X.Org Server 1.21

    Work by NVIDIA to provide separate per-client vendor mappings for GLXVND were merged to X.Org Server 1.21 Git as another step towards improving the PRIME GPU offloading support when multiple GPU drivers are at play.

    The work merged on Friday is an alternative to an earlier GLX extension proposal for controlling GLXVND dispatching for PRIME GPU offloading. But this newly-merged implementation isn't contingent upon a new GLX extension. GLXVND is the vendor neutral dispatch implementation for the X.Org Server with GLX similar to the GLVND OpenGL user-space bits.

Open Invention Network, the Linux-based patent non-aggression community, exceeds 3,000 licensees

OIN's mission is to enable Linux, its related software, and its programmers to develop and monetize without being hogtied by patent fights. In Linux's early years, this was a constant threat. Now, thanks largely to the OIN's efforts to get everyone to agree on the basic open-source principle -- that's it's better and more profitable to share than to cling to proprietary property -- open-source software has taken off in the marketplace. The OIN isn't the first to take this concept and apply it to the Unix/Linux operating system family. After Novell bought Unix from AT&T, rather than keep fighting with Berkeley Software Design Inc. (BSDO) over possible Unix IP rights violations in BSD/OS, an early, commercial BSD Unix, Noorda famously declared that he'd rather compete in the marketplace than in court. This Unix case was settled in 1994. That was a one off. The OIN, which has grown by 50% in the last two years, has turned patent non-aggression into policy for thousands of companies. By agreeing to the OIN license, members gain access to patented inventions worth hundreds of millions of dollars while promoting a favorable environment for Linux and related open source software.

Leftovers: IBM, Mozilla and SUSE

  • What Is Razee, and Why IBM Open Sourced It
    The continuous delivery software that's been doing the heavy lifting on IBM's global Kubernetes platform is now open source.
  • View Source 5 comes to Amsterdam
    Mozilla’s View Source Conference is back for a fifth year, this time in Amsterdam, September 30 – October 1, 2019. Tickets are available now.
  • SUSE & SAP “A 20 years of Partnership”
  • SUSE on the IO500 List for HPC Storage
    If you haven’t been hanging around the Ceph world for a bit, you may not realize that Ceph was originally intended to provide a distributed file-system to service HPC clusters.  While this was the original intent, Ceph has taken a round-a-bout path to relevance in this space, especially given that we are only supporting multiple active MDS servers since the Luminous release.  The result is that we are, only now, really starting to see adoption in the HPC space, and mostly for the second tier storage needs. Enter, the science project.  Given an all-flash environment on SATA SSDS with a fast storage pool on Intel Optane for the metadata, would it be possible to provide a reasonable storage environment for HPC clusters?
