Hi All, Thanks I am able to successfully get the cpu1 p-states though I am having trouble cpu cores c states. I understand that in the "read_data" function it is accomplished though after modifying for c1 core i am not able to get proper c states update. It always shows c0 and c1 core c0 state 100%. How to validate both cores c states? Also how these core states can be mapped to power consumption, if at least over all cpu power consumption can be calculated?
