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;
Members
-
sType
is the type of this structure. -
pNext
isNULL
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.
