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;


  • 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.


Valid Usage (Implicit)
  • VUID-VkPhysicalDevicePerformanceQueryFeaturesKHR-sType-sType
