  • Intel Announces Iris Xe Desktop Graphics For OEMs

    Intel today announced Iris Xe (DG1) discrete graphics cards are coming to OEMs with ASUS and Colorful being among the initial partners.

    The initial Iris Xe desktop graphics cards feature 80 execution units and a 30 Watt TDP. This is not the high-end, high performance desktop graphics but seems to largely be the Xe MAX discrete laptop graphics (but with 16 less EUs) now fitted for PCI Express cards for the desktop. The OEM cards are expected to feature 4GB of LPDDR4X memory. Other details are still light.

  • Nvidia Gets Certifiable About Systems

    If the emergence of Nvidia in datacenter compute shows anything, it is the value of controlling the software stack as you come to dominate the compute – and the revenue and profits – in the hardware stack.

    When it comes to AI, the combination of open source frameworks from the wider AI community, which Nvidia contributes to, and closed source libraries and tools that make up the Nvidia GPU Compute software stack that is underpinned by the CUDA environment, gives Nvidia the kind of control over a complete software/hardware stack that we have not seen in the datacenter since the RISC/Unix server days of the dot-com boom and earlier with proprietary systems from IBM, DEC, and HP, as well as IBM mainframes since the dawn of the data processing age.

    There are some differences this time around, and they are significant. The operating system is consequential, of course, but with all AI workloads being deployed on Linux, it really doesn’t matter which one you pick. Linux is about as interchangeable as DRAM memory modules in the server and it really comes down to preferences and a few technical differentiations. And to a certain extent, the X86 server that houses the Nvidia GPUs is fairly interchangeable, too. But fi you want to make GPU compute fluid and easy, then you have to realize that not every can – or wants to – buy an Nvidia DGX-A100 or DGX-2 system. Hyperscalers and cloud builders have their own ODM suppliers, enterprises have their own OEM suppliers, and they want to be able to run the Nvidia AI stack on platforms from their suppliers rather than having to add a new vendor into the mix.

  • NVIDIA 460.39 Linux Driver Brings RTX 30 Laptop Enablement, Improved 5.10+ Kernel Support

  • VKD3D-Proton begins work to support DirectX Raytracing on Linux | GamingOnLinux

    There's a few mountains that Steam Play Proton still needs to climb over the next few years, to enable more Windows games and more features in those games to work under Linux. One big one is at least in progress.

    Ray Tracing being one of the big things in gaming tech now, thanks to both AMD and NVIDIA having Ray Tracing cards out in the wild. With that, we can expect more games to begin using it.

    Thankfully, VKD3D-Proton, which is the Valve-funded fork of vkd3d to work with Direct3D 12 has a Pull Request open with the start of the work towards supporting Ray Tracing. Keep in mind though, while exciting for Steam Play Proton users, this is far from complete and not enabled directly for games as of yet as stated in the PR "Don't expose any features to app yet, but allow overriding FL to 12.2 for local testing while bringing up DXR.".

  • Mike Blumenkrantz: Samplin

    The goal in this post is to migrate a truckload block of code I wrote to handle sampler updating out of zink and into Gallium, thereby creating several days worth of rebase work for myself but also removing a costly codepath from the driver thread.

    The first step in getting sampler creation to work right in zink is getting Gallium to create samplers with the correct filters in accordance with Chapter 42 of the Vulkan Spec:

    VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT specifies that if VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT is also set, an image view can be used with a sampler that has either of magFilter or minFilter set to VK_FILTER_LINEAR, or mipmapMode set to VK_SAMPLER_MIPMAP_MODE_LINEAR. If VK_FORMAT_FEATURE_BLIT_SRC_BIT is also set, an image can be used as the srcImage to vkCmdBlitImage2KHR and vkCmdBlitImage with a filter of VK_FILTER_LINEAR. This bit must only be exposed for formats that also support the VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT or VK_FORMAT_FEATURE_BLIT_SRC_BIT.

    If the format being queried is a depth/stencil format, this bit only specifies that the depth aspect (not the stencil aspect) of an image of this format supports linear filtering, and that linear filtering of the depth aspect is supported whether depth compare is enabled in the sampler or not. If this bit is not present, linear filtering with depth compare disabled is unsupported and linear filtering with depth compare enabled is supported, but may compute the filtered value in an implementation-dependent manner which differs from the normal rules of linear filtering. The resulting value must be in the range [0,1] and should be proportional to, or a weighted average of, the number of comparison passes or failures.

Red Hat/Fedora Leftovers

  • Red Hat Refines Kubernetes for Both Traditional and Cloud-Native Applications with Latest Version of Red Hat OpenShift

    Red Hat, Inc., the world's leading provider of open source solutions, today announced Red Hat OpenShift 4.7, the latest version of the industry’s leading enterprise Kubernetes platform. Designed to simplify and accelerate application modernization, the latest version of Red Hat OpenShift is based on Kubernetes 1.20 and helps remove the strain on IT teams as they seek to unite traditional applications with cloud-native. All of these new capabilities are built on the consistent platform that Red Hat OpenShift provides across the open hybrid cloud.

  • Contribute at the Fedora Audio, Kernel 5.11 and i18n test days

    Fedora test days are events where anyone can help make sure changes in Fedora work well in an upcoming release. Fedora community members often participate, and the public is welcome at these events. If you’ve never contributed to Fedora before, this is a perfect way to get started.

  • Red Hat opens the door for both VMs and containers in its latest OpenShift release | ZDNet

    Kubernetes is great for managing containers. But, as popular as containers are, we're still running a lot of applications on virtual machines (VM). Wouldn't it be nice if you could use Kubernetes to orchestrate both your containers and VMs? Red Hat certainly thinks so, and with the release of Red Hat OpenShift 4.7, you can use their Kubernetes distribution to manage both your older mission-critical and newer cloud-native applications.

  • QElectroTech version 0.80 - Remi's RPM repository - Blog

    RPM of QElectroTech version 0.80, an application to design electric diagrams, are available in remi for Fedora and Enterprise Linux ≥ 8. A bit more than 1 year after the version 0.70 release, the project have just released a new major version of their electric diagrams editor.

The Innovation Lab: A Space for Creative Learning

The reason why we use System76 to power all the computers in the space is because I’m a big supporter of Linux in general, and System76 has been really consistent and helpful. I think the openness of System76 definitely gives the students the ability to experiment and the freedom to break stuff in a creative environment, without being too constrained by proprietary software.

GNOME Foundation and Linux Foundation Leftovers

  • GNOME 40 Beta has been Released

    Anyone looking to test the beta for the upcoming GNOME 40 release can now do so. On the heels of the alpha release of GNOME 40, the developers have announced the availability of the beta, which includes a number of improvements and bug fixes. Of course, the biggest change to GNOME is the new horizontal Activities Overview, which makes for a much-improved workflow on the desktop. With the desktops residing at the top of the Overview, it is now easier to drag and drop an application to the specific desktop you want. It’s far more intuitive and efficient. This new layout also improves usage with touch screen navigation and faster overall performance. Another hotly anticipated change comes by way of how multi-monitor support will work with the new horizontal Activities Overview. GNOME 40 will default to only showing workspaces on the primary display, with the top bar and the Activities Overview on both displays.
