  • Freedreno's MSM DRM Driver Wires In DEVFREQ Re-Clocking Support

    Freedreno open-source Qualcomm Adreno driver creator Rob Clark has sent in the set of updates for the MSM DRM driver targeting the Linux 4.16 kernel.

    The MSM Direct Rendering Manager updates for DRM-Next to go into Linux 4.16 are a bit late for the DRM staging, but these changes are mostly small. Besides some bug fixes and other minor code changes, the main feature addition for MSM in Linux 4.16 is DEVFREQ support for controlling the GPU clock frequency.

  • The Linux Foundation Announces New Linux on Azure Training Course [Ed: The Linux Foundation works for Microsoft now. Corrupted by the money. Microsoft meanwhile attacks Linux with patents.]
  • Automotive Grade Linux gets support from Toyota and Amazon as it eyes autonomous driving

    Open-source software was once something that large businesses shied away from, but over the course of the last few years, it’s made inroads into virtually every enterprise company. With Automotive Grade Linux (AGL), the Linux Foundation hosts a project that aims to bring open source to the car industry. As the AGL group announced at CES in Las Vegas today, Toyota and Amazon have now signed up to support the project, as well.

    Toyota, which is using AGL in the 2018 Camry, is joining as a platinum member, while Amazon opted for the silver level. Indeed, you may have seen another Toyota and Amazon mashup today, which is probably no coincidence.

  • R600 Gallium3D Gets More Fixes, Experimental SB Tessellation Support

    If you are still running with a pre-GCN AMD graphics card, a number of R600 Gallium3D commits landed in Mesa Git over night as well as an interesting patch series on the Mesa mailing list.

    Hitting Mesa 17.4-dev Git a few hours ago were a number of R600 Gallium3D fixes. This time around the various fixes come courtesy of VMware's Roland Scheidegger, a long time Mesa developer. They are a variety of minor fixes. It's nice to see nevertheless as R600g doesn't get too much action these days.

  • xf86-video-intel Gets Coffee Lake Support

    The xf86-video-intel DDX driver now has support for the first "Coffee Lake" processors.

  • The Current CPU Driver Usage Difference Between RADV/RadeonSI & NVIDIA

    Yesterday I posted some fresh GPU/driver benchmark results for discrete AMD Radeon and NVIDIA GeForce graphics cards. These were some of the most competitive numbers yet we've seen out of the open-source RadeonSI OpenGL and RADV drivers while using the latest Linux 4.15 kernel, especially for the GTX 1060 vs. RX 580 battle. In the comments were requests to see some CPU utilization numbers, including from one of the Radeon Linux developers, so here is a look at how the CPU usage compares.

    With having some spare cycles this morning on that Core i7 8700K "Coffee Lake" desktop, I ran a CPU usage comparison with various Linux games when using the Radeon RX 580 (on Linux 4.15 + Mesa 17.4-dev + LLVM 6.0 SVN) vs. the comparable GeForce GTX 1060 (on Linux 4.15 + NVIDIA 390.12) for showing the latest CPU utilization difference for both OpenGL and Vulkan games.

  • RADV Vulkan Driver Now Supports VK_EXT_discard_rectangles

    RADV co-founder Bas Nieuwenhuizen has landed support for the Vulkan VK_EXT_discard_rectangles extension within Mesa 17.4-dev.

  • RADV Gets Another Optimization For Micro-Benchmarks

    David Airlie and Bas Nieuwenhuizen's work on the RADV open-source Vulkan driver is quite relentless. David has posted yet another patch working on further optimizing the performance of this unofficial Radeon Vulkan driver living within Mesa.

  • The NVIDIA 390 Driver Is Playing Nicely With Linux 4.15 Kernel

    For those NVIDIA Linux users reliant upon the proprietary driver and wanting to upgrade to the Linux 4.15 kernel that will be officially released within the next two weeks, the 390.12 driver is playing nicely.

    Earlier NVIDIA driver releases ran into compatibility issues with the Linux 4.15 interfaces following the merge window (not due to KPTI, as some other FUD previously passed around by others). But with last week's NVIDIA 390.12 beta it has been working fine atop the Linux 4.15 Git kernel, including when Kernel Page Table Isolation is enabled for Meltdown prevention. (Retpoline support has yet to be mainlined, haven't tested the NVIDIA driver there yet to formally confirm if any breakage may happen.)

  • AMDGPU Queues More Fixes For Linux 4.16

    AMD sent in a fair number of AMDGPU updates slated for Linux 4.16 but now hitting the cut-off for major feature updates for DRM-Next code looking to make it into 4.16, AMD has submitted some fixes.

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 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.
