# VkPhysicalDevicePerformanceQueryPropertiesKHR(3) Manual Page

## Name

VkPhysicalDevicePerformanceQueryPropertiesKHR - Structure describing performance query properties for an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDevicePerformanceQueryPropertiesKHR` structure is defined as:

    // Provided by VK_KHR_performance_query
    typedef struct VkPhysicalDevicePerformanceQueryPropertiesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           allowCommandBufferQueryCopies;
    } VkPhysicalDevicePerformanceQueryPropertiesKHR;

## Members

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

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

- `allowCommandBufferQueryCopies` is `VK_TRUE` if the performance query pools are allowed to be used with vkCmdCopyQueryPoolResults.

## Description

If the `VkPhysicalDevicePerformanceQueryPropertiesKHR` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

- VUID-VkPhysicalDevicePerformanceQueryPropertiesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PERFORMANCE_QUERY_PROPERTIES_KHR`
