    VkDevice                                    device,
    VkPerformanceParameterTypeINTEL             parameter,
    VkPerformanceValueINTEL*                    pValue);

Parameters

  • device is the logical device to query.

  • parameter is the parameter to query.

  • pValue is a pointer to a VkPerformanceValueINTEL structure in which the type and value of the parameter are returned.
