# VkPhysicalDevicePerformanceQueryFeaturesKHR(3) Manual Page

## Name

VkPhysicalDevicePerformanceQueryFeaturesKHR - Structure describing performance query support for an implementation

Loading… please wait.

## C Specification

To query supported performance counter query pool features, call vkGetPhysicalDeviceFeatures2 with a `VkPhysicalDevicePerformanceQueryFeaturesKHR` structure included in the `pNext` chain of its `pFeatures` parameter.

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

- `sType` is the type of 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

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PERFORMANCE_QUERY_FEATURES_KHR`
