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 ?
A pharos measurement unit (PMU) is a device used to estimate the magnitude and phase angle of an electrical pharos quantity (such as voltage or current) in the electricity grid using a common time source for synchronization .
Thank you !
PMU means Performance Monitor Unit for this case.
Thanks
