Description
Currently I am working with the Sysman API to measure power consumption and I am encountering an issue where zesDeviceEnumPowerDomains returns 0 consistently when running it on an integrated GPU (Device: Intel(R) UHD Graphics 770). However, when running on a discrete GPU it returns 1 (Device: Intel(R) Arc(TM) A770 Graphics).
I am working on Linux for both GPUs and driver version: 24.13.29138.29 for both.
Is this expected behaviour for integrated GPUs to return 0 power domains with zesDeviceEnumPowerDomains?
If so, is there an alternative way to measure the power consumption of integrated GPUs using the Level Zero API?
Thanks

Research direction
Start with the Level Zero Sysman API entry point zesDeviceEnumPowerDomains and compare its behavior for the reported integrated and discrete GPU devices on Linux. Determine whether zero power domains is expected for integrated GPUs and identify whether the API documents an alternative power-measurement path; done means a clear answer supported by the API behavior or documentation.
