  • Raspberry Pi 4 V3D Driver Reaches OpenGL ES 3.1 Conformance

    The V3D Gallium3D driver that most notably offers the open-source graphics support for the Raspberry Pi 4 is now an official OpenGL ES 3.1 implementation.

    Consulting firm Igalia has continued working on the V3D driver since Eric Anholt left Broadcom. Igalia had ironed out OpenGL ES 3.1 support and last month also went on to begin tackling geometry shaders and more.

  • Iago Toral: I am working on the Raspberry Pi 4 Mesa V3D driver

    Yeah… this blog post is well overdue, but better late than never! So yes, I am currently working on progressing the Raspberry Pi 4 Mesa driver stack, together with my Igalian colleagues Piñeiro and Chema, continuing the fantastic work started by Eric Anholt on the Mesa V3D driver.

    The Raspberry Pi 4 sports a Video Core VI GPU that is capable of OpenGL ES 3.2, so it is a big update from the Raspberry Pi 3, which could only do OpenGL ES 2.0. Another big change with the Raspberry Pi 4 is that the Mesa v3d driver is the driver used by default with Raspbian. Because both GPUs are quite different, Eric had to write an all new driver for the Raspberry Pi 4, and that is why there are two drivers in Mesa: the VC4 driver is for the Raspberry Pi 3, while the V3D driver targets the Raspberry Pi 4.

  • Raspberry Pi 4 V3D driver gets Geometry Shaders

    I actually landed this in Mesa back in December but never got to announce it anywhere. The implementation passes all the tests available in the Khronos Conformance Tests Suite (CTS). If you give this a try and find any bugs, please report them here with the V3D tag.

  • Raspberry Pi 4 V3D driver gets OpenGL ES 3.1 conformance

    So continuing with the news, here is a fairly recent one: as the tile states, I am happy to announce that the Raspberry Pi 4 is now an OpenGL ES 3.1 conformant product!. This means that the Mesa V3D driver has successfully passed a whole lot of tests designed to validate the OpenGL ES 3.1 feature set, which should be a good sign of driver quality and correctness.

    It should be noted that the Raspberry Pi 4 shipped with a V3D driver exposing OpenGL ES 3.0, so this also means that on top of all the bugfixes that we implemented for conformance, the driver has also gained new functionality! Particularly, we merged Eric’s previous work to enable Compute Shaders.

postmarketOS in 2020-02

Long time readers may ask themselves: what's with the strange title? Where's the traditional "xyz days of postmarketOS" post? Truth is, that this is a low-key update post, one that is rather "rushed out" in a few hours instead of spending a whole week on adding all the fancy photos and gifs webm animations and so on. Consider this the minimal effort of making the project not look dead on the homepage, while not getting too distracted from the deep development lands that our minds are sunken into. We are on track with our project direction 2020 plans. In a nutshell, we will create a stable releases of postmarketOS based on Alpine stable, while still having the development channel based on Alpine edge. Furthermore, the status of supported devices will become clearer. The PinePhone, possibly the Librem 5 and few more will be labeled as officially supported in their deviceinfo and in the wiki. postmarketOS should be usable as daily driver on these. All other devices will be categorized further, depending on active maintainer count and what is working. Think of it like the AUR: still useful, but sometimes broken and you need to know what you are doing when using these. The devices will get split into their own git repository, so one can use the device packages with both the "edge" and "latest" (stable!) channel of all other packages. @ollieparanoid and @Minecrell are evolving pmbootstrap as needed.

KDE: Cutelyst 2.10.0 and SimpleMail 2, Okular Examined, FOSDEM & Plasma Mobile Sprint

  • Cutelyst 2.10.0 and SimpleMail v2 released!

    Cutelyst the C++/Qt Web framework and SimpleMailQt just got new releases. Cutelyst received many important bugfixes and if you are compiling it with View::Email it also requires SimpleMail 2, the latter got an Async API which is on production for a few months, allowing for a non-blocking send mail experience.

  • Okular is an open source universal document viewer for Windows, Linux and macOS

    Wouldn't it be nice if you had one program to view them all? That's exactly what Okular does. It's an open source universal document viewer for Windows, Linux and macOS. The program is made by KDE, a name Linux users should be familiar with, among other creations they are the ones behind the popular Kubuntu (Ubuntu + KDE Software) distro. Let's begin touring the interface. The sidepanel on the left can be used to jump to the Contents, Thumbnails, Reviews and Bookmarks sections. Select one of the options and the list of corresponding items are displayed in the panel to the right of the sidebar. The Contents option lists each section/chapter in a document, along with the sub-items, page numbers, etc. The Thumbnail mode pane displays a preview of each page in the document, you can scroll through it and click to go to the selected page. The Reviews pane contain the annotations that have been made on the document. If you don't have any, you can add some by hitting the F6 key or from the Tools menu > Review. Bookmarks are custom links that you have added, i.e., if you bookmark a page it will be displayed in the side-panel for future reference. Hit Ctrl + B to bookmark a page.

  • FOSDEM & Plasma Mobile Sprint

    Last week I decided to take KDE Itinerary for a test tour. Between the train rides there was also time for some KDE stuff. FOSDEM After writing an exam on Friday afternoon I took a train to Frankfurt. I did so not to enjoy the beautiful scenery of the area around Frankfurt central station at night but to be able to catch an early train towards Bruxelles for my first time at FOSDEM. It has been a great experience to meet so many people interested in what KDE does at the KDE booth. It also was awesome to meet all the folks that are working hard on making Linux on the phone become a thing.

Want to be an innovative company? Adopt enterprise open source

Nearly all IT professionals (95%) agree that enterprise open source is important, with 75% of professionals citing it as "extremely important," a Red Hat report found. Enterprise open source isn't just a trend, but a growing movement, as 77% of respondents expect their organizations to increase open source use in the next 12 months. "Historically, open source was seen [mainly] in web infrastructure," said Gordon Haff, Red Hat technology evangelist. "What you're seeing today is how open source is becoming a space where companies and individuals come together to collaborate in new areas of technology." Read more
