Not that I know of. Rui, any ideas?

Piledriver? What f/m/s is that?

Because I have a PD here - AMD FX(tm)-8350 Eight-Core Processor -
F15hM02 and sensors gives only this below. But my PD doesn't have
X86_FEATURE_ACC_POWER.

$ sensors
k10temp-pci-00c3
Adapter: PCI adapter
temp1:        +18.4°C  (high = +70.0°C)
                       (crit = +90.0°C, hyst = +87.0°C)

fam15h_power-pci-00c4
Adapter: PCI adapter
power1:       19.38 W  (crit = 125.19 W)

radeon-pci-0100
Adapter: PCI adapter
temp1:        +85.0°C

Do you mean this PCI adapter thing?

I can get it right up to crit when building a kernel:

power1:      124.76 W  (crit = 125.19 W)
