Hi,
I just compiled and flashed the lastest master on my KGPE-D16 with pretty much
the default config. My board has only one of the CPU sockets populated with an
Opteron 6276. Things seem to work fine so far, except the power consumption.
The "sensors" command reports a CPU power consumption of about ~85W (!) in idle:
---
k10temp-pci-00cb
Adapter: PCI adapter
temp1: +21.2°C (high = +70.0°C)
fam15h_power-pci-00c4
Adapter: PCI adapter
power1: 85.13 W (crit = 115.11 W)
nouveau-pci-0500
Adapter: PCI adapter
GPU core: +1.01 V (min = +0.60 V, max = +1.20 V)
fan1: 0 RPM
temp1: +37.0°C (high = +95.0°C, hyst = +3.0°C)
(crit = +105.0°C, hyst = +5.0°C)
(emerg = +135.0°C, hyst = +5.0°C)
k10temp-pci-00c3
Adapter: PCI adapter
temp1: +24.1°C (high = +70.0°C)

With the vendor bios, the power consumption reported by "sensors" was just
about the half - around 43W. I measured the consumption also on the power
socket, and the whole systems seems to draw around 91W in idle (which is
strange, since the GPU + hard drives + fans certainly don't take only 6W, but
yeah...). Anyways, with the vendor bios, the power consumption of the whole
system was around 60W (tested with a different power supply, but as a rough
measure I guess this is representative).
In coreboot's menuconfig, I can't select any power saving options or such as it
was possible for other boards, which leaves me a bit puzzled.
Anyone having simular issues?
Cheers, Daniel
