thanks for your replies, I have just compiled the module for my kernel
version (3.16) with the patch applied and it returns these values:

fam15h_power-pci-00c4
Adapter: PCI adapter
power1:       10.56 W  (crit =  65.18 W)

the crit value is correct (the TDP of the a4-4000 is 65W) but the
actual usage is "fixed", always the same even at 100% usage of all cpu
cores and the integrated gpu

so the readings are incorrect and the patch is useless


I have strange readings also for the other drivers concerned with
monitoring my cpu/gpu:

k10temp-pci-00c3
Adapter: PCI adapter
temp1:         +0.0 C  (high = +70.0 C)
                       (crit = +70.0 C, hyst = +69.0 C)

radeon-pci-0008
Adapter: PCI adapter
temp1:         -1.0 C  (crit = +120.0 C, hyst = +90.0 C)

but at least they are incremented under full load and, reading the docs,
they are not really physical degrees, but some other measuring unit

thanks & c-ya!
