  • Pipeline Statistics Queries Wired Up For Intel ANV Vulkan Driver

    Pipeline statistics queries is the latest Vulkan capability being added to the Intel "ANV" Mesa Vulkan driver.

    Pipeline statistics queries allow applications to query a set of Vulkan pipeline counters. Developers interested in learning more about the feature can see the Vulkan documentation.

  • SUSE Developers Publish Radeon GCN Backend Code For GCC Compiler

    While the AMDGPU "GCN" compiler support in LLVM is quite mature now, the GNU Compiler Collection (GCC) hasn't yet received a full-fledged GCN compiler back-end for AMD GPUs. SUSE developers have been working on that for AMD and today they have published their code branch. This GCN back-end for GCC is primarily focused on compute capabilities rather than compiling graphics shaders.

  • xf86-video-ati 7.9 / xf86-video-amdgpu 1.3 DDX Driver Updates
  • Trying Out The New OpenGL Threaded Dispatch In Mesa 17.1

    At the beginning of today, OpenGL threaded dispatch landed in Mesa as work that's existed in patch form for years but was recently revived for Mesa Git due to the potential for significant performance gains in select scenarios.

  • Open Source Radeon & AMDGPU Linux Drivers Updated for AMD GPUs with Improvements

    Michel Dänzer announced today the general availability of new maintenance updates for the open source AMDGPU (xf86-video-amdgpu) and Radeon (xf86-video-ati) graphics drivers.

    xf86-video-ati 7.9.0 and xf86-video-amdgpu 1.3.0 are now available for download and they are coming soon to a GNU/Linux distro near you to improve your gaming experience if you're using an AMD Radeon graphics card.

    Both releases come with the ability to use DRM render nodes for DRI3 clients if they are available, and allow the TearFree option to be toggled at runtime by using a RandR output property called "TearFree."

  • NVIDIA might have more open drivers in future on Linux

    Here’s an interesting one, a developer from NVIDIA noted on the Linux Kernel Mailing List that NVIDIA has been designing some new open source drivers. So I did some digging and got an interesting response.

  • Hammering The AMD Ryzen 7 1800X With An Intense, Threaded Workload

    Today I got around to running a very heavy/demanding, very real-world workload on the AMD Ryzen 7 1800X that I've been meaning to test with this Zen CPU.

    The workload I've been running on the Ryzen 7 1800X the past few hours is that of Open Porous Media, the open-source OPM project is a growing initiative around research and simulators for modeling and simulation of porous media processes, including a reservoir simulator and permeability upscaling. This sort of workload has relevance in areas like oil and natural gas industries.

Baidu puts open source deep learning into smartphones

A year after it open sourced its PaddlePaddle deep learning suite, Baidu has dropped another piece of AI tech into the public domain – a project to put AI on smartphones. Mobile Deep Learning (MDL) landed at GitHub under the MIT license a day ago, along with the exhortation “Be all eagerness to see it”. MDL is a convolution-based neural network designed to fit on a mobile device. Baidu said it is suitable for applications such as recognising objects in an image using a smartphone's camera.

  • Ataribox runs Linux on AMD chip and will cost at least $250
    Atari released more details about its Ataribox game console today, disclosing for the first time that the machine will run Linux on an Advanced Micro Devices processor and cost $250 to $300. In an exclusive interview last week with GamesBeat, Ataribox creator and general manager Feargal Mac (short for Mac Conuladh) said Atari will begin a crowdfunding campaign on Indiegogo this fall and launch the Ataribox in the spring of 2018. The Ataribox will launch with a large back catalog of the publisher’s classic games. The idea is to create a box that makes people feel nostalgic about the past, but it’s also capable of running the independent games they want to play today, like Minecraft or Terraria.
  • Linux 4.14 + ROCm Might End Up Working Out For Kaveri & Carrizo APUs
    It looks like the upstream Linux 4.14 kernel may end up playing nicely with the ROCm OpenCL compute stack, if you are on a Kaveri or Carrizo system. While ROCm is promising as AMD's open-source compute stack complete with OpenCL 1.2+ support, its downside is that for now not all of the necessary changes to the Linux kernel drivers, LLVM Clang compiler infrastructure, and other components are yet living in their upstream repositories. So for now it can be a bit hairy to setup ROCm compute on your own system, especially if running a distribution without official ROCm packages. AMD developers are working to get all their changes upstreamed in each of the respective sources, but it's not something that will happen overnight and given the nature of Linux kernel development, etc, is something that will still take months longer to complete.
  • Latest Linux kernel release candidate was a sticky mess
    Linus Torvalds is not noted as having the most even of tempers, but after a weekend spent scuba diving a glitch in the latest Linux kernel release candidate saw the Linux overlord merely label the mess "nasty". The release cycle was following its usual cadence when Torvalds announced Linux 4.14 release candidate 2, just after 5:00PM on Sunday, September 24th.
  • Linus Torvalds Announces the Second Release Candidate of Linux Kernel 4.14 LTS
    Development of the Linux 4.14 kernel series continues with the second Release Candidate (RC) milestone, which Linus Torvalds himself announces this past weekend. The update brings more updated drivers and various improvements. Linus Torvalds kicked off the development of Linux kernel 4.14 last week when he announced the first Release Candidate, and now the second RC is available packed full of goodies. These include updated networking, GPU, and RDMA drivers, improvements to the x86, ARM, PowerPC, PA-RISC, MIPS, and s390 hardware architectures, various core networking, filesystem, and documentation changes.
