  • Intel's Vulkan Driver Squeezes Another Optimization Into Mesa 20.0

    Patches written two months ago for Intel's ANV open-source Vulkan driver have now been merged ahead of the imminent Mesa 20.0 feature freeze and branching.

    The work worth mentioning is allowing HiZ in read-only depth layouts. "These layouts don't mean "sampled" they mean the same thing as DEPTH_STENCIL_OPTIMAL only the client promises to not write the depth or stencil buffer as indicated. Since HiZ depth testing is much faster than non-HiZ depth testing, we really don't want to disable HiZ for these."

  • RadeonSI Introduces A Live Shader Cache With Mesa 20.0

    In addition to the AMD RadeonSI Gallium3D driver's on-disk shader cache and in-memory shader cache there is now a "live shader cache" to help with deduplication of compiled shader objects.

    AMD's Marek Olšák landed this live shader cache on Friday. The introduction of this new caching level stems from the behavior of when games concert separate D3D shaders into linked GLSL shaders, the same vertex shader is often used with many different fragment shaders. In introducing this live shader cache of the compiled shader objects, for affected titles there should now be fewer resident shaders and fewer shader state changes.

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.

  • 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.
