-This driver permits reading of registers providing power information
-of AMD Family 15h processors.
-For AMD Family 15h processors the following power values can be
-calculated using different processor northbridge function registers:
-* BasePwrWatts: Specifies in watts the maximum amount of power
- consumed by the processor for NB and logic external to the core.
-* ProcessorPwrWatts: Specifies in watts the maximum amount of power
- the processor can support.
-* CurrPwrWatts: Specifies in watts the current amount of power being
- consumed by the processor.
-This driver provides ProcessorPwrWatts and CurrPwrWatts:
-* power1_crit (ProcessorPwrWatts)
-* power1_input (CurrPwrWatts)
-On multi-node processors the calculated value is for the entire
-package and not for a single node. Thus the driver creates sysfs
-attributes only for internal node0 of a multi-node processor.
