Hello Zoran,
I really appreciate your help. I was able to resolve the problem on late
Friday. I cannot exactly tell what the reason was, however, I set up a fresh
install of coreboot, just using my old .config and microcode. Then I saw that
the board gets past the microcode update. I must have

Nope, I am only comparing with highest backlight now, so it is 12.8W versus
10.0W here.

Is this 12.8W compared to 7.5W (i.e. with lowest backlight)?

Hi again,
I did some more experiments with the vendor BIOS and made the following
observations:
- disabling "cpu power management" makes the idle consumption raise to 12,8W
- disabling "PCI Bus power management" and "PCI express power management" makes
the idle consumption raise to 13,3W
- disa

Hi all,
thank you again for the suggestions!
First thing: VGABIOS. I was able to extract the blob (the hint in the wiki is a
bit hidden and the introduction of the section is a bit misleading btw) and
re-ran the measurements using the proprietary VGA BIOS:
Idle: 13,4W
Stress: 37,2W
So they va

Hi Daniel,
first thing: We never got to the deepest processor sleep states (C3, C4)
when we originally ported coreboot for the GM45 chipset. But we didn't
see a difference in power consumption back then on the Roda/RK9.

Hi Andrey and lynxis,
thank you for the quick reply and your suggestions. I followed Andrey's advice
and here are the results (only with full screen brightness):
Coreboot with idle=poll: 15,8W
Coreboot running "stress": 37,2W
Vendor BIOS with idle=poll: 15W
Vendor BIOS with intel_pstate=disable
13 matches
