Description

This extension adds a mechanism to provide feedback to an application about pipeline creation, with the specific goal of allowing a feedback loop between build systems and in-the-field application executions to ensure effective pipeline caches are shipped to customers.

New Structures

• PipelineCreationFeedbackEXT

• Extending GraphicsPipelineCreateInfo, ComputePipelineCreateInfo, RayTracingPipelineCreateInfoNV, RayTracingPipelineCreateInfoKHR, ExecutionGraphPipelineCreateInfoAMDX, DataGraphPipelineCreateInfoARM:

  • PipelineCreationFeedbackCreateInfoEXT

New Enums

• PipelineCreationFeedbackFlagBitsEXT

New Bitmasks

• PipelineCreationFeedbackFlagsEXT

New Enum Constants

• EXT_PIPELINE_CREATION_FEEDBACK_EXTENSION_NAME

• EXT_PIPELINE_CREATION_FEEDBACK_SPEC_VERSION

• Extending PipelineCreationFeedbackFlagBits:

  • PIPELINE_CREATION_FEEDBACK_APPLICATION_PIPELINE_CACHE_HIT_BIT_EXT
  • PIPELINE_CREATION_FEEDBACK_BASE_PIPELINE_ACCELERATION_BIT_EXT
  • PIPELINE_CREATION_FEEDBACK_VALID_BIT_EXT

• Extending StructureType:

  • STRUCTURE_TYPE_PIPELINE_CREATION_FEEDBACK_CREATE_INFO_EXT

Promotion to Vulkan 1.3

Vulkan APIs in this extension are included in core Vulkan 1.3, with the EXT 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.
