# VkPerformanceParameterTypeINTEL(3) Manual Page

## Name

VkPerformanceParameterTypeINTEL - Parameters that can be queried

## 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.
