C Specification

The VkPhysicalDevicePerformanceQueryFeaturesKHR structure is defined as:

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

Members

The members of the VkPhysicalDevicePerformanceQueryFeaturesKHR structure describe the following implementation-dependent features:

Description

  • sType is the type of this structure.

  • pNext is NULL or a pointer to an extension-specific structure.

  • performanceCounterQueryPools is VK_TRUE if the physical device supports performance counter query pools.

  • performanceCounterMultipleQueryPools is VK_TRUE if the physical device supports using multiple performance query pools in a primary command buffer and secondary command buffers executed within it.

Valid Usage (Implicit)
  • sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PERFORMANCE_QUERY_FEATURES_KHR

To query performance counter query pool features supported call vkGetPhysicalDeviceFeatures2 with a VkPhysicalDevicePerformanceQueryFeaturesKHR structure included in the pNext chain of its pFeatures parameter. The VkPhysicalDevicePerformanceQueryFeaturesKHR structure can also be in the pNext chain of a VkDeviceCreateInfo structure, in which case it controls which additional features are enabled in the device.
