C Specification

Possible values of VkPerformanceValueINTEL::type, specifying the type of the data returned in VkPerformanceValueINTEL::data, are:

  • VK_PERFORMANCE_VALUE_TYPE_UINT32_INTEL specifies that unsigned 32-bit integer data is returned in data.value32.

  • VK_PERFORMANCE_VALUE_TYPE_UINT64_INTEL specifies that unsigned 64-bit integer data is returned in data.value64.

  • VK_PERFORMANCE_VALUE_TYPE_FLOAT_INTEL specifies that floating-point data is returned in data.valueFloat.

  • VK_PERFORMANCE_VALUE_TYPE_BOOL_INTEL specifies that VkBool32 data is returned in data.valueBool.

  • VK_PERFORMANCE_VALUE_TYPE_STRING_INTEL specifies that a pointer to a null-terminated UTF-8 string is returned in data.valueString. The pointer is valid for the lifetime of the device parameter passed to vkGetPerformanceParameterINTEL.
