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:
-
sType
is a VkStructureType value identifying 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.
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.
