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

• Extending PhysicalDeviceFeatures2, DeviceCreateInfo:

  • PhysicalDeviceShaderIntegerDotProductFeaturesKHR

• Extending PhysicalDeviceProperties2:

  • PhysicalDeviceShaderIntegerDotProductPropertiesKHR

New Enum Constants

• KHR_SHADER_INTEGER_DOT_PRODUCT_EXTENSION_NAME

• KHR_SHADER_INTEGER_DOT_PRODUCT_SPEC_VERSION

• Extending StructureType:

  • STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_INTEGER_DOT_PRODUCT_FEATURES_KHR
  • 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.

New SPIR-V Capabilities

• DotProductInputAllKHR

• DotProductInput4x8BitKHR
• DotProductInput4x8BitPackedKHR
• DotProductKHR

Version History

• Revision 1, 2021-06-16 (Kévin Petit)
