# VkPerformanceQuerySubmitInfoKHR(3) Manual Page

## Name

VkPerformanceQuerySubmitInfoKHR - Structure indicating which counter pass index is active for performance queries

Loading… please wait.

## C Specification

The `VkPerformanceQuerySubmitInfoKHR` structure is defined as:

    // Provided by VK_KHR_performance_query
    typedef struct VkPerformanceQuerySubmitInfoKHR {
        VkStructureType    sType;
        const void*        pNext;
        uint32_t           counterPassIndex;
    } VkPerformanceQuerySubmitInfoKHR;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `counterPassIndex` specifies which counter pass index is active.

## Description

If the `VkSubmitInfo`::`pNext` chain does not include this structure, the batch defaults to use counter pass index 0.

Valid Usage

- VUID-VkPerformanceQuerySubmitInfoKHR-counterPassIndex-03221
  `counterPassIndex` must be less than the number of counter passes required by any queries within the batch. The required number of counter passes for a performance query is obtained by calling vkGetPhysicalDeviceQueueFamilyPerformanceQueryPassesKHR

Valid Usage (Implicit)

- VUID-VkPerformanceQuerySubmitInfoKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PERFORMANCE_QUERY_SUBMIT_INFO_KHR`
