17-----------
18
19This driver permits reading of registers providing power information
20of AMD Family 15h and 16h processors.
21
22For AMD Family 15h and 16h processors the following power values can
23be calculated using different processor northbridge function
24registers:
25
26* BasePwrWatts: Specifies in watts the maximum amount of power
27  consumed by the processor for NB and logic external to the core.
28* ProcessorPwrWatts: Specifies in watts the maximum amount of power
29  the processor can support.
30* CurrPwrWatts: Specifies in watts the current amount of power being
31  consumed by the processor.
32
33This driver provides ProcessorPwrWatts and CurrPwrWatts:
34* power1_crit (ProcessorPwrWatts)
35* power1_input (CurrPwrWatts)
36
37On multi-node processors the calculated value is for the entire
38package and not for a single node. Thus the driver creates sysfs
39attributes only for internal node0 of a multi-node processor.
