C Specification

Possible values of vkGetPerformanceParameterINTEL::parameter, specifying a performance query feature, are:

typedef enum VkPerformanceParameterTypeINTEL {
    VK_PERFORMANCE_PARAMETER_TYPE_HW_COUNTERS_SUPPORTED_INTEL = 0,
    VK_PERFORMANCE_PARAMETER_TYPE_STREAM_MARKER_VALID_BITS_INTEL = 1,
    VK_PERFORMANCE_PARAMETER_TYPE_MAX_ENUM_INTEL = 0x7FFFFFFF
} VkPerformanceParameterTypeINTEL;

Description

  • VK_PERFORMANCE_PARAMETER_TYPE_HW_COUNTERS_SUPPORTED_INTEL has a boolean result which tells whether hardware counters can be captured.

  • VK_PERFORMANCE_PARAMETER_TYPE_STREAM_MARKER_VALID_BITS_INTEL has a 32 bits integer result which tells how many bits can be written into the VkPerformanceValueINTEL value.
