VkPhysicalDevicePerformanceQueryFeaturesKHR

The VkPhysicalDevicePerformanceQueryFeaturesKHR structure is defined as:

typedef struct VkPhysicalDevicePerformanceQueryFeaturesKHR {
    VkStructureType sType;
    void* pNext;
    VkBool32 performanceCounterQueryPools;
    VkBool32 performanceCounterMultipleQueryPools;
} VkPhysicalDevicePerformanceQueryFeaturesKHR;

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.

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.
