# VkPhysicalDevicePerformanceQueryFeaturesKHR(3) Manual Page

## Name

VkPhysicalDevicePerformanceQueryFeaturesKHR - Structure describing performance query support for an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDevicePerformanceQueryFeaturesKHR` structure is defined as:

    // Provided by VK_KHR_performance_query
    typedef struct VkPhysicalDevicePerformanceQueryFeaturesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           performanceCounterQueryPools;
        VkBool32           performanceCounterMultipleQueryPools;
    } VkPhysicalDevicePerformanceQueryFeaturesKHR;

## Members

This structure describes the following features:

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

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

- `performanceCounterQueryPools` indicates whether the implementation supports performance counter query pools.

- `performanceCounterMultipleQueryPools` indicates whether the implementation supports using multiple performance query pools in a primary command buffer and secondary command buffers executed within it.

## Description

If the `VkPhysicalDevicePerformanceQueryFeaturesKHR` structure is included in the `pNext` chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by `VkPhysicalDevicePerformanceQueryFeaturesKHR`, it must add an instance of the structure, with the desired feature members set to `VK_TRUE`, to the `pNext` chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)

- VUID-VkPhysicalDevicePerformanceQueryFeaturesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PERFORMANCE_QUERY_FEATURES_KHR`
