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