# VkQueryPoolPerformanceCreateInfoKHR(3) Manual Page

## Name

VkQueryPoolPerformanceCreateInfoKHR - Structure specifying parameters of a newly created performance query pool

Loading… please wait.

## C Specification

The `VkQueryPoolPerformanceCreateInfoKHR` structure is defined as:

    // Provided by VK_KHR_performance_query
    typedef struct VkQueryPoolPerformanceCreateInfoKHR {
        VkStructureType    sType;
        const void*        pNext;
        uint32_t           queueFamilyIndex;
        uint32_t           counterIndexCount;
        const uint32_t*    pCounterIndices;
    } VkQueryPoolPerformanceCreateInfoKHR;

## Members

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

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

- `queueFamilyIndex` is the queue family index to create this performance query pool for.

- `counterIndexCount` is the length of the `pCounterIndices` array.

- `pCounterIndices` is a pointer to an array of indices into the vkEnumeratePhysicalDeviceQueueFamilyPerformanceQueryCountersKHR::`pCounters` to enable in this performance query pool.

## Description

Valid Usage

- VUID-VkQueryPoolPerformanceCreateInfoKHR-queueFamilyIndex-03236
  `queueFamilyIndex` must be a valid queue family index of the device

- VUID-VkQueryPoolPerformanceCreateInfoKHR-performanceCounterQueryPools-03237
  The `performanceCounterQueryPools` feature must be enabled

- VUID-VkQueryPoolPerformanceCreateInfoKHR-pCounterIndices-03321
  Each element of `pCounterIndices` must be in the range of counters reported by `vkEnumeratePhysicalDeviceQueueFamilyPerformanceQueryCountersKHR` for the queue family specified in `queueFamilyIndex`

Valid Usage (Implicit)

- VUID-VkQueryPoolPerformanceCreateInfoKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_QUERY_POOL_PERFORMANCE_CREATE_INFO_KHR`

- VUID-VkQueryPoolPerformanceCreateInfoKHR-pCounterIndices-parameter
  `pCounterIndices` must be a valid pointer to an array of `counterIndexCount` `uint32_t` values

- VUID-VkQueryPoolPerformanceCreateInfoKHR-counterIndexCount-arraylength
  `counterIndexCount` must be greater than `0`
