Description

This extension adds support for the integer dot product SPIR-V instructions defined in SPV_KHR_integer_dot_product. These instructions are particularly useful for neural network inference and training but find uses in other general-purpose compute applications as well.

New Structures

New Enum Constants

  • VK_KHR_SHADER_INTEGER_DOT_PRODUCT_EXTENSION_NAME

  • VK_KHR_SHADER_INTEGER_DOT_PRODUCT_SPEC_VERSION

  • Extending VkStructureType:

    • VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_INTEGER_DOT_PRODUCT_FEATURES_KHR

    • VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_INTEGER_DOT_PRODUCT_PROPERTIES_KHR

Promotion to Vulkan 1.3

Vulkan APIs in this extension are included in core Vulkan 1.3, with the KHR suffix omitted. External interactions defined by this extension, such as SPIR-V token names, retain their original names. The original Vulkan API names are still available as aliases of the core functionality.
