Graphics: Libdrm, AMDGPU, AR/VR and Gallium3D

  • Libdrm 2.4.100 Released With Bits For Intel Elkhart Lake, Tiger Lake Graphics

    AMD open-source developer Marek Olšák on Wednesday released libdrm 2.4.100 as the newest feature update to this Mesa DRM library. On the AMD front there are a number of RAS tests added, a new amdgpu_cs_query_reset_state2 interface, and other expanded AMDGPU test coverage.

  • AMDGPU GFX9+ Format Modifiers Being Worked On For Better DCC Handling

    RADV Vulkan driver developer Bas Nieuwenhuizen of Google has ventured into kernel space in working on format modifiers support for Vega/GFX9 and newer. This DRM format modifiers support for GFX9+ is being worked on for helping to evaluate when delta color compression (DCC) can be used and any other requirements around that DCC handling. Bas explained, "This is particularly useful to determine if we can use DCC, and whether we need an extra display compatible DCC metadata plane."

  • Free software support for virtual and augmented reality

    A talk at the recent X.Org Developers Conference in Montréal, Canada looked at support for "XR" in free software. XR is an umbrella term that includes both virtual reality (VR) and augmented reality (AR). In the talk, Joey Ferwerda and Christoph Haag from Collabora gave an overview of XR and the Monado project that provides support for those types of applications. Ferwerda started by defining the term "HMD", which predates VR and AR. It is a head-mounted display, which basically means "taking a screen and some sensors and duct-taping it to your face". All of the devices that are being used for XR are HMDs. They typically include some kind of tracking system to determine the position and orientation of the HMD itself. Multiple different technologies, including inertial measurement units (IMUs), photodiodes, lasers, and cameras, are used to do the tracking depending on the device and its use case. AR is intended to augment the real world with extra information; the user sees the real world around them, but various kinds of status and additional data is tagged to objects or locations in their view of the world. AR is a rather over-hyped technology these days, he said. The general idea is that users would wear glasses that would augment their view in some fashion, but, unfortunately, what most people think of as AR is Pokémon Go. VR uses two screens, one for each eye, to create a 3D world that the user inhabits and can interact with in some fashion. Instead of seeing the real world, the user sees a completely separate world. There are two words that are often used to describe the feel of VR, he said: "presence" and "immersion". That means users are aware of themselves as being part of the VR environment. XR encompasses both. Ferwerda said that he is not really sure what the "X" stands for; he has heard "cross reality" and "mixed reality" for XR. Haag said that "extended reality" was another definition that he had heard.

  • Intel Now Aiming For Gallium3D OpenGL Default For Mesa 20.0

    For the better part of two years now Intel has been working on this new "Iris" Gallium3D driver for supporting Broadwell "Gen8" graphics and newer as the eventual replacement to their long-standing i965 classic driver. With Tiger Lake "Gen12" Xe graphics, it's in fact Iris Gallium3D only. In our testing of Broadwell through the *lakes, this Gallium3D driver has been working out terrific on Mesa 19.2 stable and Mesa 19.3 development. But it looks like Intel is going to play it safe and punt the default change-over to next quarter's Mesa 20.0 cycle.

Embedded system cross-development with Ubuntu Core

There are fundamental differences between developing general-purpose software applications and making software for embedded systems. Embedded systems software runs on resource-constrained hardware, in contrast to general-purpose server or client applications that run on more capable hardware. For this reason, embedded system software is not directly developed on the electronic board it will run on – referred to as the target. It is rather developed on a computer – the host – that has a higher computational capacity than the target board. Read more

LibreOffice: LibreOffice 6.2.8, FOSDEM 2020 and LibreOffice Conference 2019

  • LibreOffice 6.2.8 is available, the last release of the 6.2 family

    The Document Foundation announces LibreOffice 6.2.8, the last minor release of the LibreOffice 6.2 family. All users of LibreOffice 6.2.x versions should update immediately for enhanced security, and be prepared to upgrade to LibreOffice 6.3.4 as soon as it becomes available in December. For enterprise class deployments, TDF strongly recommends sourcing LibreOffice from one of the ecosystem partners to get long-term supported releases, dedicated assistance, custom new features and bug fixes, and other benefits. Also, the work done by ecosystem partners flows back into the LibreOffice project, benefiting everyone. LibreOffice’s individual users are helped by a global community of volunteers: https://www.libreoffice.org/get-help/community-support/. On the website and the wiki there are guides, manuals, tutorials and HowTos. Donations help us to make all of these resources available. LibreOffice users are invited to join the community at https://ask.libreoffice.org, where they can get and provide user-to-user support. While TDF can not provide commercial level support, there are guides, manuals, tutorials and HowTos on the website and the wiki. Your donations help us make these available.

  • LibreOffice 6.2.8 Arrives as the Last in the Series, Prepare for LibreOffice 6.3

    The Document Foundation released today the eight and final maintenance update for the LibreOffice 6.2 open-source and cross-platform office suite series. LibreOffice 6.2.8 is here one and a half months after the release of LibreOffice 6.2.7, which was announced in early September alongside the first point release of the latest LibreOffice 6.3 series.

SUSE/OpenSUSE Leftovers

  • Plasma, Applications, Frameworks arrive in Latest Tumbleweed Snapshot

    The most recent snapshot, 20191014, updated several packages around KDE’s projects. Plasma 5.17.0 arrived in the snapshot and there are some extraordinary changes to the new version. The release announcement says this new version is as lightweight and thrifty with resources as ever before. The start-up scripts were converted from a slower Bash to a faster C++ and now run asynchronously, which means it can run several tasks simultaneously, instead of having to run them one after another. Improvements to the widget editing User Experience were made and the Night Color feature became available, which subtly changes the hue and brightness of the elements on the screen when it gets dark; this diminishes glare and makes it more relaxing to the eyes. The same snapshot brought KDE Applications 19.08.2 and the second version of the 19.08 release improved High-DPI support in Konsole and other applications; there were many bugs fixes as well and KMail can once again save messages directly to remote folders. There was more KDE packages arriving in Tumbleweed with the update of KDE Frameworks 5.63.0; KIO, Kirigami and KTextEditor had the most bug fixes in frameworks latest release. The Tumbleweed snapshot had several other software packages updated like the file system utilities package e2fsprogs 1.45.4, which addressed Common Vulnerabilities and Exposures CVE-2019-5094 where an attacker would have been able to corrupt a ext4 partition. The 3.6.10 version of gnutls added support for deterministic Elliptic Curve Digital Signature Algorithm (ECDSA) / Digital Signature Algorithm (DSA). Text editor Nano updated to version 4.5 and offers a new ‘tabgives’ command allowing users to specify per syntax whatthe key should produce. The php7 7.3.10 version modified some patches and fixed some bugs. With all these changes, the snapshot is trending at a stable rating of 95, according to the Tumbleweed snapshot reviewer.

  • Multi-cloud Management: Stratos and Kubernetes

    At the recent Cloud Foundry Summit EU in the Netherlands, Neil MacDougall and Troy Topnik of SUSE presented a talk demonstrating and describing the work that SUSE has done to extend the Stratos management interface to include support for Kubernetes and Helm. They talked about how SUSE has used the Stratos extension mechanism to add new endpoint types for Kubernetes and Helm and we showed some of the features that SUSE has been developing. They wrapped things up by talking about where SUSE is headed next in extending Stratos beyond Cloud Foundry into a Multi-cloud Management interface.
