## C Specification

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

    // Provided by VK_INTEL_performance_query
    typedef enum VkPerformanceParameterTypeINTEL {
        VK_PERFORMANCE_PARAMETER_TYPE_HW_COUNTERS_SUPPORTED_INTEL = 0,
        VK_PERFORMANCE_PARAMETER_TYPE_STREAM_MARKER_VALID_BITS_INTEL = 1,
    } VkPerformanceParameterTypeINTEL;

## Description
