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
isNULL
or a pointer to an extension-specific structure. -
performanceCounterQueryPools
isVK_TRUE
if the physical device supports performance counter query pools. -
performanceCounterMultipleQueryPools
isVK_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 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.
