GPU Performance API (GPUPerfAPI) is a powerful library providing access to GPU Performance Counters to help analyze the performance and characteristics of applications using a Radeon GPU. GPUPerfAPI v3.11 adds support for raytracing counters in Vulkan on RDNA2 (Radeon RX 6000 Series) hardware: RayTriTests, and RayBoxTests: These counters collect the number of ray intersections for triangles and boxes, respectively. TotalRayTests: This counter collects the aggregated number of ray-box and ray-triangle intersection tests. RayTestsPerWave: This counter collects ray intersection test count at a more granular level – per wave.

Join us to help drive the evolution of Machine Learning acceleration standards. ML developers lament the growing fragmentation in the ML ecosystem. Khronos knows that open and royalty-free standards can play an essential role in reducing fragmentation, reducing costs, and providing the industry participants the opportunity to grow. Based on feedback from previous summit and discussions, Khronos is creating a coalition of interested parties to meet the needs of the ML community for hardware acceleration.

Vulkan Portability aims to counter platform fragmentation by encouraging layered implementations of Vulkan functionality over Metal, DX12, and other APIs. Vulkan Portability enables Vulkan applications to be reliably deployed across diverse platforms. Khronos released a provisional version of Vulkan Portability Extension 1.0 in September 2020. The VK_KHR_portability_subset extension allows a non-conformant Vulkan implementation to be built on top of another non-Vulkan graphics API and identifies the difference between that implementation and a fully-conformant native Vulkan implementation. The extension is detailed in the Vulkan Specification. For already released applications that are expecting to see only fully Vulkan conformant devices, a backward-compatibility issue exists. To solve the backward-compatibility issue, Khronos has released the new Vulkan Loader extension, VK_KHR_portability_enumeration. The purpose of this extension is to enable or disable enumeration of portability (non-conformant) implementations.

Khronos has introduced a new extension named VK_EXT_graphics_pipeline_library that allows for shaders to be compiled much earlier than at full Pipeline State Object (PSO) creation time. By leveraging this extension, I was able to avoid many causes of frame hitches due to PSOs being late-created at draw time in the Source 2 Vulkan renderer. The extension spec was released today and SDK support will follow soon, you can track the release status at https://github.com/KhronosGroup/Vulkan-Docs/issues/1808.

A new blog from Collabora shows the latest utilities and helpers to make writing Vulkan drivers easier and demonstrates the latest Mesa best practices.

With the release of Mesa 22.1, Lavapipe exposes Vulkan 1.3 for running atop CPUs.

The Advanced Media Framework SDK provides developers with optimal access to AMD GPUs for multimedia processing. In the latest release, v1.4.24.0, AMD has enabled Vulkan support for HEVC Encoder (Navi+) and have improved H264 encoding on Vulkan for both Windows & Linux Navi+.

Basemark launched GPUScore, an all-new GPU performance benchmarking suite to produce the most professional measurements in the industry. GPUScore will consist of three different testing suites. The first one is GPUScore: Relic of LIfe compares Vulkan and DirectX accelerated ray tracing performance.

Today, The Khronos Group announced the public release of the royalty-free Vulkan Safety-Critical (SC) 1.0 API Specification to enable safety-critical industries to deploy state-of-the-art GPU graphics and compute acceleration while meeting the highest levels of functional safety requirements. The Vulkan SC Conformance Test Suite is also freely available in open source, and multiple vendors have officially-conformant Vulkan SC 1.0 implementations. Industry feedback on the specification is welcome at the Vulkan SC specification GitHub repository.
