I am trying to profile my workload on LNL and MTL. There are different CPU cores in such machines. It includes P-Cores, E-Cores Ultra Efficient Cores, iGPU, & NPU. I am not sure if it is supported. System Details.

The error I get is as follows.
vtune: Warning: Memory bandwidth collection requires the sampling driver to be enabled on the system. Disable the "Analyze memory bandwidth" knob to proceed with the analysis or install the sampling driver on the system. See the Sampling Drivers help topic for more details. Note that memory bandwidth collection is not possible if you are profiling inside a virtualized environment.
vtune: Error: Current OS kernel does not support driverless collection on hybrid CPUs. Consider loading the VTune Profiler sampling driver using root credentials or updating the OS kernel.
aps Error: Cannot run the collection.
