C Specification

Some performance query features of a device can be discovered with the call:

// Provided by VK_INTEL_performance_query
VkResult vkGetPerformanceParameterINTEL(
    VkDevice                                    device,
    VkPerformanceParameterTypeINTEL             parameter,
    VkPerformanceValueINTEL*                    pValue);


  • 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.


Valid Usage (Implicit)
  • VUID-vkGetPerformanceParameterINTEL-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkGetPerformanceParameterINTEL-parameter-parameter
    parameter must be a valid VkPerformanceParameterTypeINTEL value

  • VUID-vkGetPerformanceParameterINTEL-pValue-parameter
    pValue must be a valid pointer to a VkPerformanceValueINTEL structure

Return Codes

On failure, this command returns
