  • Intel To Try Flipping IOMMU On By Default For Linux Graphics

    Longtime Intel open-source graphics driver developer Chris Wilson today sent out a set of patches attempting to enable IOMMU coverage for graphics by default.

    With the exception of the Broadwell generation of graphics, at this point he believes there is little fallout from turning on IOMMU for their graphics by default. One of the benefits to flipping on IOMMU is that instead of memory corruption that might not be detected, there will be a DMAR fault that is reported and can be tracked via their CI infrastructure, etc.

  • Navi 14 Will Work Its Way Into A Workstation Graphics Card

    When it comes to Navi graphics processors in workstation cards, there's now confirmation of at least one coming with the "Navi 14" GPU.

    A patch adding a new Navi 14 PCI ID to the AMDGPU Linux kernel DRM driver is for a "workstation SKU" mentioned in the patch message. Details beyond that clear confirmation of Navi 14 for a workstation model aren't known. There are two "workstation" Navi 14 PCI IDs added of 0x7341 and 0x7347.

    We've seen the various driver bits of Navi 14 getting ready but this is the first time we've seen Navi 14 brought up in the context of workstation parts. We're also starting to see some SRIOV bits for Navi as likely further feature work with workstation in mind.

  • Gthree – ready to play

    Today I made a new release of Gthree, version 0.2.0.

    Newly added in this release is support for Raycaster, which is important if you’re making interactive 3D applications. For example, it’s used if you want clicks on the window to pick a 3D object from the scene. See the interactive demo for an example of this.

Default window manager switched to CTWM in NetBSD-current

For more than 20 years, NetBSD has shipped X11 with the "classic" default window manager of twm. However, it's been showing its age for a long time now. In 2015, ctwm was imported, but after that no progress was made. ctwm is a fork of twm with some extra features - the primary advantages are that it's still incredibly lightweight, but highly configurable, and has support for virtual desktops, as well as a NetBSD-compatible license and ongoing development. Thanks to its configuration options, we can provide a default experience that's much more usable to people experienced with other operating systems. Read more

Red Hat/Fedora Leftovers

  • Call an existing REST service with Apache Camel K

    With the release of Apache Camel K, it is possible to create and deploy integrations with existing applications that are quicker and more lightweight than ever. In many cases, calling an existing REST endpoint is the best way to connect a new system to an existing one. Take the example of a cafe serving coffee. What happens when the cafe wants to allow customers to use a delivery service like GrubHub? You would only need to introduce a single Camel K integration to connect the cafe and GrubHub systems. In this article, I will show you how to create a Camel K integration that calls an existing REST service and uses its existing data format. For the data format, I have a Maven project configured with Java objects. Ideally, you would have this packaged and available in a Nexus repository. For the purpose of my demonstration, I utilized JitPack, which lets me have my dependency available in a repository directly from my GitHub code. See the GitHub repository associated with this demo for the data format code and directions for getting it into JitPack.

  • Build a data streaming pipeline using Kafka Streams and Quarkus

    In typical data warehousing systems, data is first accumulated and then processed. But with the advent of new technologies, it is now possible to process data as and when it arrives. We call this real-time data processing. In real-time processing, data streams through pipelines; i.e., moving from one system to another. Data gets generated from static sources (like databases) or real-time systems (like transactional applications), and then gets filtered, transformed, and finally stored in a database or pushed to several other systems for further processing. The other systems can then follow the same cycle—i.e., filter, transform, store, or push to other systems. In this article, we will build a Quarkus application that streams and processes data in real-time using Kafka Streams. As we go through the example, you will learn how to apply Kafka concepts such as joins, windows, processors, state stores, punctuators, and interactive queries. By the end of the article, you will have the architecture for a realistic data streaming pipeline in Quarkus.

  • Fedora 32 : Can be better? part 012.

    Pidgin is a chat program which lets you log into accounts on multiple chat networks simultaneously. Pidgin can be install on multiple operating systems and platforms. Pidgin is compatible with the following chat networks out of the box: I.R.C., Jabber/XMPP, Bonjour, Gadu-Gadu, IRC, Novell GroupWise Messenger, Lotus Sametime, SILC, SIMPLE, and Zephyr. Can it be better? The only problems a user in need of help may have are in the command line environment. Obviously, in this case, this application cannot be used. I would suggest building a terminal application like WeeChat dedicated to Fedora users and including I.R.C channels. Now, let's install this application.

Touchégg 2.0.0 Released: A Linux Multi-Touch Gesture Recognizer App

For years, it has continued to work in every desktop environment. However, as the Linux desktop has advanced a lot, Touchégg fails to work on desktop environments using modern technologies like Wayland compositor. Therefore, Jose has now revised, completely rewrote the old version, and released a new version 2.0.0 after more than years of gap. The new release aims to make the app compatible with new technology stacks incorporated in GNOME, KDE, and other desktops. Read more

Linux 5.10: Freedreno/MSM Driver and Broadcom Ethernet

  • MSM Adreno DRM Driver For Linux 5.10 Has DisplayPort, Per-Process Pagetables

    Rob Clark who founded the Freedreno/MSM driver project and current Googler sent in the MSM direct rendering manager driver updates targeting the upcoming Linux 5.10 merge window. This time around the Adreno kernel graphics/display driver has some notable additions. With Linux 5.10 the MSM DRM driver now has DisplayPort output support for Adreno hardware with DP outputs.

  • Broadcom Has 200G Ethernet Link Speed Support Coming To Its Driver For Linux 5.10

    Broadcom engineers have prepared their Linux network driver infrastructure for supporting 200G link speeds. Coming to Broadcom's "bnxt_en" Linux network driver in Linux 5.10 are the necessary alterations for handling 200G links. It was back in late 2018 when Broadcom first announced the world's first 200G Ethernet controller utilizing 50G PAM-4 and PCI Express 4.0. Now as we approach the end of 2020 and prepping for an interesting 2021 of new hardware, bnxt_en is ready with this 200G Ethernet link speed.
