  • AMD Posts Last KFD Kernel Patches For Discrete GPUs, Needed For Upstream ROCm

    AMD has posted their remaining patches for now for getting the discrete GPU support upstream in the AMDKFD "Kernel Fusion Driver" that is part of their ROCm compute stack.

  • Xilinx ZynqMP DisplayPort DRM/KMS Driver Posted

    Xilinx is interested in contributing the latest DRM/KMS driver upstream.

    Xilinx has developed a new DRM/KMS driver for their DisplayPort sub-system that is part of their ZynqMP SoC. The Xilinx ZynqMP SoC has a full display pipeline and two planes and DisplayPort 1.2 encoder.

  • Tessellation Shaders Land For RadeonSI NIR Backend

    The work led by Valve Linux driver developer Timothy Arceri on adding tessellation shader support to RadeonSI's NIR code-path has been merged to Mesa 17.4-dev Git.

    RadeonSI Gallium3D has been working on a NIR back-end for eventually supporting SPIR-V ingestion as needed for OpenGL 4.6 compliance with code sharing with the RADV Vulkan code. Eventually though RadeonSI may eventually switch to using NIR completely as its intermediate representation. But before that can happen, the RadeonSI NIR support needs to get to parity with its existing OpenGL support when tied to TGSI IR.

  • Red Hat's Latest Nouveau Developer Posts Updated NIR Code

    Not only is RadeonSI working on NIR support but Red Hat has begun working on NIR support for the open-source NVIDIA "Nouveau" driver as part of a compute effort and possible Vulkan support in the future.

    As written about last month, longtime Nouveau contributor Karol Herbst has joined Red Hat and his first public-facing project is developing NIR support for Nouveau. In the original patch series Karol explained he's working on NIR support for Nouveau in order to get SPIR-V (the Vulkan / OpenCL IR) support moving. Their expressed focus right now is on SPIR-V compute support but this would also be a step towards Vulkan for this open-source, reverse-engineered NVIDIA Linux graphics driver.

  • Broadcom's Open-Source VC5 OpenGL & Vulkan Support Improving

    Broadcom open-source driver developer Eric Anholt has written his first status update on the VC5 driver activities of the new year.

    VC5 is the new Broadcom GPU capable of Vulkan and much greater OpenGL capabilities than the VC4 graphics processor most well known for being within current-generation Raspberry Pi devices. Eric has been working on the bring-up of the open-source VC5 driver stack for the past half-year and he continues making progress on getting the VC5 OpenGL Gallium3D driver closer to parity to the long-standing VC4 driver as well as working on "BCMV" as the new Broadcom Vulkan driver still in its early stages.

openSUSE Tumbleweed Users Get LibreOffice 6.1, Mozilla Firefox 61, and FFmpeg 4

The month of July 2018 was pretty busy for the openSUSE Tumbleweed development team, and the first two weeks of the month already delivered dozens of updates and security fixes. openSUSE developer Dominique Leuenberger reports that a total of nine snapshots have been released in July 2018 for the openSUSE Tumbleweed Linux operating system series, which follows a rolling release model where users install once and receive updates forever. As expected, these 9 snapshots bring numerous updates and bugfixes. Read more

Linux Kernel/Foundation

  • Linux Foundation Brings Power of Open Source to Energy Sector
    The Linux Foundation launched on July 12 its latest effort—LF Energy, an open-source coalition for the energy and power management sector. The LF Energy coalition is being backed by French transmission system operation RTE, Vanderbilt University and the European Network of Transmission System Operators (ENTSO-E). With LF Energy, the Linux Foundation is aiming to replicate the success it has seen in other sectors, including networking, automotive, financial services and cloud computing.
  • Marek Squeezes More Performance Out Of RadeonSI In CPU-Bound Scenarios
    AMD's leading open-source RadeonSI Gallium3D developer, Marek Olšák, sent out a new patch series this week aiming to benefit this Radeon OpenGL driver's performance in CPU-bound scenarios. The patch series is a set of command submission optimizations aimed to help trivial CPU-bound benchmarks to varying extents. In the very trivial glxgears, the patch series is able to improve the maximum frame-rates by around 10%.
  • Intel Sends In A Final Batch Of DRM Feature Updates Targeting Linux 4.19
    After several big feature pull requests of new "i915" Intel DRM driver features landing in DRM-Next for Linux 4.19, the Intel open-source developers have sent in what they believe to be their last batch of feature changes for queuing this next kernel cycle.
