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

• VkPipelineCreationFeedbackEXT
• Extending VkGraphicsPipelineCreateInfo, VkComputePipelineCreateInfo, VkRayTracingPipelineCreateInfoNV, VkRayTracingPipelineCreateInfoKHR, VkExecutionGraphPipelineCreateInfoAMDX:
  • VkPipelineCreationFeedbackCreateInfoEXT

New Enums

• VkPipelineCreationFeedbackFlagBitsEXT

New Bitmasks

• VkPipelineCreationFeedbackFlagsEXT

New Enum Constants

• VK_EXT_PIPELINE_CREATION_FEEDBACK_EXTENSION_NAME
• VK_EXT_PIPELINE_CREATION_FEEDBACK_SPEC_VERSION
• Extending VkPipelineCreationFeedbackFlagBits:
  • VK_PIPELINE_CREATION_FEEDBACK_APPLICATION_PIPELINE_CACHE_HIT_BIT_EXT
  • VK_PIPELINE_CREATION_FEEDBACK_BASE_PIPELINE_ACCELERATION_BIT_EXT
  • VK_PIPELINE_CREATION_FEEDBACK_VALID_BIT_EXT
• Extending VkStructureType:
  • VK_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.
