C Specification
Performance counters have an associated storage. This storage describes the payload of a counter result.
The performance counter storage types which may be returned in
VkPerformanceCounterKHR::storage are:
// Provided by VK_KHR_performance_query
typedef enum VkPerformanceCounterStorageKHR {
VK_PERFORMANCE_COUNTER_STORAGE_INT32_KHR = 0,
VK_PERFORMANCE_COUNTER_STORAGE_INT64_KHR = 1,
VK_PERFORMANCE_COUNTER_STORAGE_UINT32_KHR = 2,
VK_PERFORMANCE_COUNTER_STORAGE_UINT64_KHR = 3,
VK_PERFORMANCE_COUNTER_STORAGE_FLOAT32_KHR = 4,
VK_PERFORMANCE_COUNTER_STORAGE_FLOAT64_KHR = 5,
} VkPerformanceCounterStorageKHR;Description
-
VK_PERFORMANCE_COUNTER_STORAGE_INT32_KHR - the performance counter storage is a 32-bit signed integer.
-
VK_PERFORMANCE_COUNTER_STORAGE_INT64_KHR - the performance counter storage is a 64-bit signed integer.
-
VK_PERFORMANCE_COUNTER_STORAGE_UINT32_KHR - the performance counter storage is a 32-bit unsigned integer.
-
VK_PERFORMANCE_COUNTER_STORAGE_UINT64_KHR - the performance counter storage is a 64-bit unsigned integer.
-
VK_PERFORMANCE_COUNTER_STORAGE_FLOAT32_KHR - the performance counter storage is a 32-bit floating-point.
-
VK_PERFORMANCE_COUNTER_STORAGE_FLOAT64_KHR - the performance counter storage is a 64-bit floating-point.
