  • Mir 1.6 Released With New Wayland, DispmanX Platform Support

    Mir 1.6 is out today with the latest batch of features for this Ubuntu-focused display server that offers Wayland client compatibility.

    The two big additions to Mir 1.6 are on the graphics platform front. First, there is now a "Wayland platform" for running Mir as a nested compositor on top of a Wayland compositor. Secondly, the rpi-dispmanx platform is for Broadcom's DispmanX API.

  • Before Ending 2019, Vintage SiS X.Org Driver Sees A New Release

    xf86-video-sis 0.12.0 is available this week as a new version of the SiS display driver for X.Org systems in supporting Silicon Integrated Systems' display hardware.

    This X.Org user-space mode-setting driver has seen its first update in four months but prior to that it hadn't seen any update to the open-source code in three years.

  • RadeonSI Lands SDMA Copy Support For Vega/GFX9

    The RadeonSI Gallium3D driver has finally landed SDMA copy support for Vega/GFX9 graphics hardware, which should principally benefit compute shaders and other cases.

  • AMD's GPUOpen Releases Vulkan Memory Allocator 2.3

    AMD's GPUOpen team has released their first official update to the open-source Vulkan Memory Allocator project in nearly one year.

    Vulkan Memory Allocator is an easy-to-use Vulkan memory allocation library that in the two and a half years since being open-sourced has been picked up for use by multiple games/engineers, Vulkan code samples, and other projects.

  • Chromium's Ozone Wayland Back-End Is Now Considered Beta, Aiming To Ship Next Year

    For years there has been work on a Wayland back-end to Ozone, the Google component for abstracting user-interface elements and input/window handling among other tasks across platforms. It looks like in 2020 the Ozone Wayland support will be in good standing and promoted out of beta.

    We were tipped off to a recent presentation by Igalia's Alexander Dunaev on their work contributing to the Ozone Wayland code. From consulting firm Igalia's perspective, they have been focused on bringing up Ozone Wayland support in the embedded Linux context considering the number of consumer devices now shipping that use Wayland and Chromium or CEF. But all their embedded Linux work for Ozone Wayland also benefits the Linux desktop.

  • Mesa Developers Weigh Renaming Gallium "State Tracker" To "API"

    Gallium3D state tracker terminology has been around a decade now in referring to the portions of the architecture that are ultimately implementing various graphics / compute / video APIs. Marek proposed keeping the Mesa OpenGL state tracker term but in renaming the other state trackers to being "API implementations" as that terminology is technically more accurate for the likes of Clover OpenCL, VA-API, VDPAU, and the other state trackers / APIs implemented.

  • Lima Gets Tiling While Vulkan Turnip Lands SSBO + Compute Shaders

    The Lima Gallium3D driver that supports older Mali 400/450 hardware with an open-source OpenGL driver hasn't been seeing too many improvements these days compared to the likes of the Panfrost Gallium3D driver for the newer Arm Mali Bifrost/Midgard architectures. But hitting Mesa 20.0-devel yesterday was tiling support for Lima. This should improve the performance for this open-source Mali driver and also end up working around the driver's broken mipmapping support for linear textures.

  • Libinput 1.15 Is On Approach With Various Improvements/Fixes For Linux Input Handling

    Peter Hutterer has been preparing libinput 1.15 as the next update to this open-source input handling library used by Linux systems both on X.Org and Wayland.

    Compared to past releases that have seen exciting changes on supporting new input devices like the Dell Totem, scrolling enhancements, and other major additions, there isn't too much of that with libinput 1.15.

  • BT’s ‘open source’ approach will challenge Huawei’s dominance

    BT is seeking to challenge the dominance of Huawei over the industry by throwing its weight behind a new “open source” approach to buying essential network gear, the chief executive of Openreach has claimed. Clive Selley, who runs BT’s separate Openreach broadband business, said the company was seeking to push back against the existing industry structure in which a handful of suppliers, including China’s Huawei, Sweden’s Ericsson and Finland’s Nokia, hold too much power over a highly consolidated market. “We are trying to challenge them,” he told The Telegraph in an interview last week. “Because what you really want is a mix and match approach. We are trying to provoke the industry to move in that direction – more ability to mix and match [suppliers].”
