# VkPipelineCreationFeedbackCreateInfo(3) Manual Page

## Name

VkPipelineCreationFeedbackCreateInfo - Request for feedback about the creation of a pipeline

Loading… please wait.

## C Specification

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, VkDataGraphPipelineCreateInfoARM, or VkComputePipelineCreateInfo. The `VkPipelineCreationFeedbackCreateInfo` structure is defined as:

    // Provided by VK_VERSION_1_3
    typedef struct VkPipelineCreationFeedbackCreateInfo {
        VkStructureType                sType;
        const void*                    pNext;
        VkPipelineCreationFeedback*    pPipelineCreationFeedback;
        uint32_t                       pipelineStageCreationFeedbackCount;
        VkPipelineCreationFeedback*    pPipelineStageCreationFeedbacks;
    } VkPipelineCreationFeedbackCreateInfo;

or the equivalent

    // Provided by VK_EXT_pipeline_creation_feedback
    typedef VkPipelineCreationFeedbackCreateInfo VkPipelineCreationFeedbackCreateInfoEXT;

## Members

- `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.

## Description

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`.

Note | One common scenario for an implementation to skip per-stage feedback is when `VK_PIPELINE_CREATION_FEEDBACK_APPLICATION_PIPELINE_CACHE_HIT_BIT` is set in `pPipelineCreationFeedback`.

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`.

Valid Usage (Implicit)

- VUID-VkPipelineCreationFeedbackCreateInfo-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PIPELINE_CREATION_FEEDBACK_CREATE_INFO`

- VUID-VkPipelineCreationFeedbackCreateInfo-pPipelineCreationFeedback-parameter
  `pPipelineCreationFeedback` must be a valid pointer to a VkPipelineCreationFeedback structure

- VUID-VkPipelineCreationFeedbackCreateInfo-pPipelineStageCreationFeedbacks-parameter
  If `pipelineStageCreationFeedbackCount` is not `0`, `pPipelineStageCreationFeedbacks` must be a valid pointer to an array of `pipelineStageCreationFeedbackCount` VkPipelineCreationFeedback structures
