For Contex-A72, There are 4 cores for each Arm Cortex-A72.And each core has a private PMU unit which counts events from its point of view. So there are 4 PMUs for Contex-A72 processor.
I want to get the count of every PMU. How can I get it ?

AFAIK only the local core (or a debug unit) can read the local PMU registers.
