Andrew Richards, CEO and Co-founder of Codeplay Software, presents the “Can We Have Both Safety and Performance in AI for Autonomous Vehicles?” tutorial at the May 2019 Embedded Vision Summit. Andrews presentation includes discussion on how SYCL, OpenCL and Vulkan can play into Safety and Performance in vehicles.

Intel Graphics - Windows 10 DCH Driver adds Vulkan extensions

​A new release of the Intel Graphics Windows 10 DCH drivers (v26.20.100.7158) introduces four new Vulkan extensions: VK_EXT_fragment_shader_interlock, VK_EXT_buffer_device_address, VK_EXT_separate_stencil_usage, VK_KHR_uniform_buffer_standard_layout. As well, reporting support for the following OpenGL 4.6 SPIR-V extensions has been introduced: SPV_KHR_shader_ballot, SPV_KHR_shader_draw_parameters, SPV_KHR_storage_buffer_storage_class, SPV_KHR_subgroup_vote.

Intel’s “ANV” Vulkan Linux driver has now hooked into the DriConf infrastructure for handling driver tunables and workarounds. As of Friday afternoon, the Intel Vulkan driver hooks into DriConf. That was followed up by adding a toggle for vk_x11_override_min_image_count behavior. That was followed by adding a generic override for when running gfxbench. Learn more about DriConf and this change.

Geekbench 5, the latest major upgrade to Primate Labs’ cross-platform benchmark, is now available for download. The Compute Benchmark now supports Vulkan, along with CUDA, Metal, and OpenCL. Vulkan Compute Benchmarks are available on Android, Windows, and Linux.

​Vulkan 1.1.122 has been released. This update sees many internal issues resolved plus one new extension from a public issue. VK_IMG_format_pvrtc allows an application to capture performance data to be interpreted by an external application or library.

FFmpeg Adds AMD AMF Vulkan Support For Linux Users

The FFmpeg library up to this point has supported AMD’s Advanced Media Framework (AMF) library just on Windows for H.264/HEVC encoding on GPUs. The Windows code-path makes use of DirectX while now AMD AMF support for Linux via Vulkan is now exposed by the latest FFmpeg code.

bgfx popular open source cross-platform rendering library adds Vulkan renderer backend. Vulkan renderer backend will be bgfx’ default renderer on Linux, and it can be used on all supported platforms including MacOS via MoltenVK emulation.

Another blog explaining Vulkan synchronization has just been posted by @Themaister. Synchronization in Vulkan is a large hurdle to overcome when learning the API, and rather than mechanically explaining how it works, the goal in this blog is to instil a mental model in the reader. Despite its reputation for maddening complexity, it is actually understandable and quite logical once you get over the initial hurdles.

Vulkan 1.1.119 was released right after 1.1.118. In total, three new extensions have been added: VK_AMD_shader_core_properties2, VK_AMD_pipeline_compiler_control and VK_KHR_pipeline_executable_properties. The first two are AMD vendor extensions, while the most recent extension was worked on jointly by engineers from Intel, Valve, Google, NVIDIA, AMD, Arm, and Samsung. See the Change log on GitHub for additional the details.

The Khronos Group BOF day is today, July 31. For those folks that really wanted to catch some of the BOF Day sessions, but couldn’t make, we have it covered for you. Starting at 9AM PT, the morning livestream will start on YouTube. The afternoon sessions will be on a second afternoon livestream also on YouTube. Learn more about the Khronos Group BOF Day and all of the various sessions on our SIGGRAPH 2019 event page.

The Khronos Group announces new 3D Commerce Working Group and key updates to flagship standards WebGL, glTF, and Vulkan. In the spirit of continued commitment to the SIGGRAPH community of interactive graphics professionals, Khronos delivers a number of developments and initiatives, including:

  • 3D Commerce Initiative Becomes Khronos Working Group; Call for Participation Announced
  • WebGL Releases High-Impact Extensions and Ecosystem Developments
  • glTF Universal Texture Extension Drafting Underway Using Binomial’s Basis Universal Texture Technology; First Prototype Support Appears in Engines
  • glTF Tools Ecosystem Expands, Including Universal Texture Tools and glTF Import/Export in Blender 2.80
  • New Vulkan Extensions Ship; Vulkan Sees Increased Usage by CAD and Professional Authoring Tools

Khronos BOF Day at SIGGRAPH 2019–Next Week!

SIGGRAPH is next week! The conference is July 28-August 1. For those going, Khronos will be hosting several Birds of a Feather sessions. For all those folks that will not be present, we will be offering live streaming of all our sessions (glTF, WebGL, OpenXR and Vulkan) on the Khronos Group YouTube Channel, and will follow up with recorded video the following week. For complete details on all the sessions, please ask your friends and co-workers to take a look at our SIGGRAPH event page! A special thanks to our Title sponsor NVIDIA, Beer Sponsor LunarG, and Demo sponsor Cesium, for making possible the Khronos Networking Reception at the end of the day.
