C Specification
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
This structure describes the following features:
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
performanceCounterQueryPoolsindicates whether the implementation supports performance counter query pools. -
performanceCounterMultipleQueryPoolsindicates whether the implementation supports using multiple performance query pools in a primary command buffer and secondary command buffers executed within it.
Description
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.
