Servers: SUSE and Kubernetes

tuxmachines.org - Tor, 04/02/2019 - 06:50
  • SUSE Will Soon Be the Largest Independent Linux Company
  • SUSE Linux Enterprise Server for Arm 15 on AWS

    SUSE is excited to launch SUSE Linux Enterprise Server for Arm on AWS, backed by a Trial Subscription Program and also available via AWS Spot Instances to get started on your next innovation. Today’s innovators are testing new architecture designs to build products in increasingly more efficient, cost-effective, scalable, and secure ways. The Arm architecture is critical in this diverse ecosystem and its’ adoption by Amazon Web Services in November 2018 was a huge milestone for the market. While Arm is prevalent in the mobile market and the chip most likely powering the device in your pocket – the technology is also critical in powering IoT devices and applications in the machine learning space.

  • What Is Kubernetes?

    Kubernetes (pronounced “CUBE-A-NET-IS”) is an open-source platform that helps manage container applications such as Docker. Whether you are looking to automate or scale these containers across multiple hosts, Kubernetes can speed up deployment. To do this it may use internal components such as Kubernetes API or third-party extensions which run on Kubernetes.

    This article will help you understand the basic concepts of Kubernetes and why it is causing such a seismic shift in the server market, with vendors as well as cloud providers, such as Azure and Google Cloud, offering Kubernetes services.

  • Kubernetes v1.14 delivers production-level support for Windows nodes and Windows containers [Ed: When Kubernetes is steered by GPL violators and proprietary software thugs from VMware and Microsoft]

    The first release of Kubernetes in 2019 brings a highly anticipated feature - production-level support for Windows workloads. Up until now Windows node support in Kubernetes has been in beta, allowing many users to experiment and see the value of Kubernetes for Windows containers. While in beta, developers in the Kubernetes community and Windows Server team worked together to improve the container runtime, build a continuous testing process, and complete features needed for a good user experience. Kubernetes now officially supports adding Windows nodes as worker nodes and scheduling Windows containers, enabling a vast ecosystem of Windows applications to leverage the power of our platform.

Graphics: Running Android next to Wayland, RadeonSI Gallium3D and Vulkan

tuxmachines.org - Tor, 04/02/2019 - 02:37
  • Running Android next to Wayland

    It's now possible to run Android applications in the same graphical environment as regular Wayland Linux applications with full 3D acceleration.

    Running Android has some advantages compared to native Linux applications, for example with regard to the availability of applications and application developers.

    For current non-Android systems, this work enables a path forward to running Android applications in the same graphical environment as traditional non-Android applications are run.

  • RadeonSI Gallium3D In Mesa 19.1 Enables Parallel Shader Compile Support

    Marek Olšák of AMD kicked off the new month by finally landing support for the ARB/KHR extensions around parallel shader compile support.

    Back in February he posted the RadeonSI patches for implementing KHR_parallel_shader_compile and ARB_parallel_shader_compile extensions including the necessary work to core Mesa and Gallium3D. It's that work that has now been merged to Mesa Git.

  • Wine Lands Initial Vulkan Adapter Support For Direct3D

    As the first step towards the plans to have a Vulkan back-end to WineD3D itself for Wine mapping older versions of Direct3D to Vulkan, an initial Vulkan adapter implementation was merged today.

    CodeWeavers is pursuing a Vulkan back-end for WineD3D akin to DXVK but one that could work with older versions of Direct3D and also continuing to maintain the mature Direct3D-to-OpenGL back-end that has been the default implementation. Pursuing this modern Vulkan back-end for WineD3D could yield better performance and also potentially work on macOS in the future via MoltenVK.

Games: ProtonDB, SuperTuxKart, DXVK, Sunless Skies and Valve Index

tuxmachines.org - Tor, 04/02/2019 - 02:06
  • A quick look over ProtonDB reports for Steam Play in March 2019

    The Steam Play tracker ProtonDB just recently put out another set of reports, so here's another look at some interesting findings when going over the data. As a reminder, ProtonDB is not an official Valve site and everything should be taken with a healthy pinch of salt. That said, it's still fun to take a look at the data it provides.

  • Kodi and SuperTuxKart on Panfrost

    Back in October, Panfrost ran some simple benchmarks, like glmark. Five months later, Panfrost has grown from running benchmarks to real-world apps, like Kodi, and 3D games like SuperTuxKart and Neverball.

    Since the previous post, there have been major improvements across every part of the aspect culminating in this milestone. On the kernel side, my co-contributors Tomeu Vizoso and Rob Herring have created a modern kernel driver, suitable for mainline inclusion. Panfrost now uses this upstream-friendly driver, rather than relying on a modified legacy kernel as in the past. The new kernel module is currently under review for mainline inclusion. You can read more about this progress on Tomeu’s blog.

    Outside the kernel, however, the changes have been no less significant. Early development was constrained to our own project repositories, as the code was not yet ready to general users. In early February, thanks in part to the progress on the kernel-space, we flew out of our nest, and Panfrost was merged into upstream Mesa, the central repository for free software graphics drivers. Development now occurs in-tree in Mesa.

    We have continued decoding new aspects of the hardware and implementing support in the driver. A few miscellaneous additions include cube maps, gl_PointSize and gl_PointCoord, linear depth rendering, performance counters, and new shader instructions.

  • DXVK 1.0.2 is out with some bug fixes, d9vk seems to be progressing nicely

    Two bits of Wine-related news today with both DXVK for Vulkan-based D3D11 and D3D10 and d9vk for Vulkan-based D3D9 coming along.

  • Sunless Skies to get an exciting update next week, to make the Albion area more interesting

    Sunless Skies is a fantastic game, I've enjoyed many hours exploration in it and Failbetter Games are set to improved it. Note: You can see some previous thoughts I had here.

    The Wayfarer Update is arriving on Tuesday, 9th April and it will include a big refresh to the Albion area "with a focus on providing more to see and do during voyages". This is only the first of multiple updates coming to the game, which it seems will be free.

  • Woops - Valve accidentally put up the Valve Index, Base Station and Controllers unfinished store pages

    What could possibly be a little prank from Valve, the unfinished Steam store pages for the Valve Index, Valve Index Base Station and Valve Index Controllers went online a little too early. Yes, really, this is not a prank from us! SteamDB were quick as usual to spot it.

[$] Some slow progress on get_user_pages()

LWN.net - Tor, 04/02/2019 - 01:40
One of the surest signs that the Linux Storage, Filesystem, and Memory-Management (LSFMM) Summit is approaching is the seasonal migration of memory-management developers toward the get_user_pages() problem. This core kernel primitive is necessary for high-performance I/O to user-space memory, but its interactions with filesystems have never been reliable — or even fully specified. There are currently a couple of patch sets in circulation that are attempting to improve the situation, though a full solution still seems distant.

The new SUSE

tuxmachines.org - Tor, 04/02/2019 - 00:14

In Nashville, Tenn., at SUSECon, European Linux power SUSE CEO Nils Brauckmann said his company would soon be the largest independent Linux company. That's because, of course, IBM is acquiring Red Hat. But, simultaneously, SUSE has continued to grow for seven-straight years.

Brauckmann said, "We believe that makes our status as a truly independent open source company more important than ever. Our genuinely open-source solutions, flexible business practices, lack of enforced vendor lock-in, and exceptional service are more critical to customer and partner organizations, and our independence coincides with our single-minded focus on delivering what is best for them."

Qt 3D Studio 2.3 Released

tuxmachines.org - Pon, 04/01/2019 - 21:28

We are happy to announce the Qt 3D Studio 2.3 release is now available via the online and offline installers. Here’s a quick summary of the new features and functions in 2.3. For detailed information about the Qt 3D Studio, visit the online documentation page.

The 2.3 release introduces a new font rendering engine based on distance field font rendering. The new renderer is the default starting from 2.3 release onward. The old Qt Painter texture based can be enabled by setting an environment variable Q3DS_DISTANCE_FIELD_DISABLED to 1. The new font rendering also supports pre-generated distance field cache. The new font rendering does require Qt 5.12.2 release, with the earlier Qt releases the text rendering in using the old font rendering.

Bottomley: A Roadmap for Eliminating Patents in Open Source

LWN.net - Pon, 04/01/2019 - 17:52
James Bottomley has posted a detailed description of how patent exhaustion might be used to mostly eliminate the software patent threat to free software. "The intriguing possibility this offers us is that we may be close to an enforceable court decision (at least in the US) that would render all patents in open source owned by community members exhausted and thus unenforceable. The purpose of this blog post is to explain the current landscape and how we might be able to get the necessary missing court decisions to make this hope a reality." LWN covered the FOSDEM talk by Van Lindberg that underlies Bottomley's post.
