  • Intel Graphics Driver Patches Revived For Per-Client Engine Activity

    One of the interesting Intel Linux graphics driver patches to be sent out last year were for per-client engine reporting to allow on a per-application/process basis to see how the GPU's render/blitter/video engines were being utilized.

    That work for per-client "engine busyness" reporting went through a few rounds of review but as of Linux 5.9 there still isn't the support within Intel's i915 kernel driver.

  • Vulkan Present Timing Extension With Aim To Avoid Stuttering

    The Vulkan System Integration working group has decided to publish their work-in-progress extension on VK_EXT_present_timing as their effort to expose the presentation engine's display details and better allow scheduling a present to happen at a specific time.

    VK_EXT_present_timing is a big effort about helping to reduce stuttering and use-cases like better handling of variable refresh rate setups and other scenarios in wanting to ensure the presentation of a frame/image happens on schedule to avoid anomalies.

  • Intel Graphics Compiler 1.0.4944 Brings Many Minor Optimizations

    The Intel Graphics Compiler (IGC) that is used by their Linux OpenCL/Level-Zero compute stack as well as now being used by their Windows graphics driver and potentially their Linux OpenGL/Vulkan drivers in the future is out with a new release.

    IGC releases tend to come frequent with a large team working on this open-source graphics compiler code while the 1.0.4944 milestone is a bit of a larger release.

  • X.Org Developer's Conference 2020

    After DebConf, Linux Plumbers and Akademy, the lineup of great virtual conferences continues this week with the 2020 edition of X.Org Developer's Conference (XDC), the leading event for developers working on all things Open graphics, including the Linux kernel, Mesa, DRM, Wayland and X11.

    Taking place entirely online for the first time, XDC 2020 brings a packed schedule of talks, workshops and lightning talks spread out over three days. Collaborans will giving two presentations & a lightning talk during the week, for which you can find full details below. The entire conference will be live-streamed on YouTube (Day 1, Day 2 & Day 3), however if you would like to take part in any of the discussions, there's still time to register (free of charge)!

  • AMD Radeon Navi 2 / VCN 3.0 Supports AV1 Video Decoding

    It turns out the Radeon RX 6000 series will have AV1 hardware video decode capabilities.

    In addition to Intel Xe / Tigerlake and the NVIDIA GeForce RTX 30 series supporting AV1 hardware decoding, it's now firmed up that the next-gen Navi 2 GPUs will also have AV1 decode.

    As previously reported, the AMD next-gen GPUs feature VCN 3.0 for Video Core Next. The previous VCN 3.0 Linux/open-source patches didn't reveal AV1 capabilities but new patches out today confirm AV1 support with VCN3.

10 Open Source Static Site Generators to Create Fast and Resource-Friendly Websites

Technically, a static website means the webpages are not generated on the server dynamically. The HTML, CSS, JavaScript lie on the server in the version the end user receives it. The raw source code files are already prebuilt, the source code doesn’t change with the next server request. It’s FOSS is a dynamic website which depends on several databases and the web pages are generated and served when there’s a request from your browser. Majority of the web is powered by dynamic sites where you interact with the websites and there are plenty of content that often change. Read more

7 Amazing Linux Distributions For Kids

Linux is a very powerful operating system and that is one of the reasons why it powers a lot of servers on the Internet. Though there have been concerns about its user-friendliness which has brought about the debate of how it will overtake Mac OSX and Windows on desktop computers, I think users need to accept Linux as it is to realize its real power. Today, Linux powers a lot of machines out there, from mobile phones to tablets, laptops, workstations, servers, supercomputers, cars, air traffic control systems, refrigerators, and many more. With all this and more yet to come in the near future, as I had already stated at the beginning, Linux is the operating system for future computing. Because the future belongs to the kids of today, then introducing them to technologies that will change the future is the way to go. Therefore they have to be introduced at an early stage to start learning computer technologies and Linux as a special case. One thing common to children is curiosity and early learning can help instill a character of exploration in them when the learning environment is designed to suit them. Having looked at some quick reasons why kids should learn Linux, let us now go through a list of exciting Linux distributions that you can introduce your kids to so that they can start using and learning Linux.
