VkPipelineCreationFeedbackCreateInfo

Feedback about the creation of a particular pipeline object can be obtained by adding a VkPipelineCreationFeedbackCreateInfo structure to the pNext chain of VkGraphicsPipelineCreateInfo, VkRayTracingPipelineCreateInfoKHR, VkRayTracingPipelineCreateInfoNV, or VkComputePipelineCreateInfo. The VkPipelineCreationFeedbackCreateInfo structure is defined as:

typedef struct VkPipelineCreationFeedbackCreateInfo {
    VkStructureType sType;
    const void* pNext;
    VkPipelineCreationFeedback* pPipelineCreationFeedback;
    uint32_t pipelineStageCreationFeedbackCount;
    VkPipelineCreationFeedback* pPipelineStageCreationFeedbacks;
} VkPipelineCreationFeedbackCreateInfo;

or the equivalent

typedef VkPipelineCreationFeedbackCreateInfo VkPipelineCreationFeedbackCreateInfoEXT;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• pPipelineCreationFeedback is a pointer to a VkPipelineCreationFeedback structure.
• pipelineStageCreationFeedbackCount is the number of elements in pPipelineStageCreationFeedbacks.
• pPipelineStageCreationFeedbacks is a pointer to an array of pipelineStageCreationFeedbackCount
  VkPipelineCreationFeedback structures.

An implementation should write pipeline creation feedback to pPipelineCreationFeedback and may write pipeline stage creation feedback to pPipelineStageCreationFeedbacks. An implementation must set or clear the VK_PIPELINE_CREATION_FEEDBACK_VALID_BIT in VkPipelineCreationFeedback::flags for pPipelineCreationFeedback and every element of pPipelineStageCreationFeedbacks.

When chained to VkRayTracingPipelineCreateInfoKHR, VkRayTracingPipelineCreateInfoNV, or VkGraphicsPipelineCreateInfo, the i element of pPipelineStageCreationFeedbacks corresponds to the i element of VkRayTracingPipelineCreateInfoKHR::pStages, VkRayTracingPipelineCreateInfoNV::pStages, or VkGraphicsPipelineCreateInfo::pStages. When chained to VkComputePipelineCreateInfo, the first element of pPipelineStageCreationFeedbacks corresponds to VkComputePipelineCreateInfo::stage.
