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
-
sTypeis the type of this structure. -
pNextisNULLor a pointer to an extension-specific structure. -
performanceCounterQueryPoolsisVK_TRUEif the physical device supports performance counter query pools. -
performanceCounterMultipleQueryPoolsisVK_TRUE` if the physical device supports using multiple performance query pools in a primary command buffer and secondary command buffers executed within it.
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 can also be
included in the pNext chain of a VkDeviceCreateInfo structure,
in which case it controls which additional features are enabled in the
device.
