I guess that’s a failure to read man page. Thank you. I’ve tested disabling the port in BIOS saves me significant power vs an unloaded driver but I have a little more testing to do to see if it’s actually fully powered down or not when I do that. 10W is quite a bit.

If it's not a longer average it might not be that reliable to base a savings test on. But it may be a longer average.

This is one of the simplest example. I configured a very stripped down linux kernel and it idles at about the same watt usage as OpenBSD. I guess it's a matter of figuring out which drivers or kernel features are saving so much power. I flashed my bios to the newest one they provide and Linux uses even less power; I did not see much difference on OpenBSD.

Re: >10W idle power usage on framework laptop 12th gen 13inch
Kirill thanks for the patch, but i am still worried about the power usage. Even if i put apmd in manual mode and setperf=0, my system sucks 9-9.5W, which means the patch will not do much in my situation since any benefit from the patch comes from setperf=0. What could be taking so much power? CPUs are idling. I've tried switching to two cores with no help. I've confg'd a mostly driverless kernel and booted my system with all ports off that i could, which i'm assuming actually turns them off since i do notice a power shift. Still major power drain compared to Linux.

This is one of the simplest example. My BIOS allows me to disable the wireless and three other ports (External I/O, WIFI/Bluetooth, Finger Print, Camera). I turned all of these off and did notice a change but it was only about 1.5-2W out of the ~10W > Next, your CPU has performance cores and efficient cores. The thread > per CPU allocation on Linux is on work but it is more advanced. > > My BIOS also allows me to disable cores, but requires me to keep at least one efficiency and one performance. I did this and the kernel threads dropped to three but I didn't notice any power change. In fact, power usage seemed to go up slightly but not much. Is that expected and this is still a viable path for digging?

So I guess it just doesn’t go into the mode unless it’s well over the threshold or something.

One difference is it sets a range based on a usage algorithm while solene’s patch seems to setperf 100 or zero based on <1/3 idle with a 2 cycle (400ms) backoff. My serperf seems to be at a consistent zero in my idle tests which makes me think the patch may not help my idle tests much, but may help actual usage. > On idle this laptop has on 400 MHz, and provided patch decrease > responsibility of system when it runs on battery, but allows to win some > time on it.

To be honest I never actually verified the cycle count before. I have just recently been letting it go to full exhaustion, I almost never let it “die” so that may have something to do with it. I’ll keep an eye on it. > > Some batteries skimp on the design vs. last capacity too. Most often I > have seen them to be about the same value forever. Or a too high design > value is tricked and if you open the cell it is not corresponding. This one has degraded quite a bit so I’m thinking it’s being honest with me. I’ve been through quite a few cycles with it because I assumed the system wasnt doing any DC pass through. One interesting thing with this battery that I’ve just noticed is that the bios has an option to limit charge to a given percentage. If I limit the charge to something, say 60%, and monitor the current when it gets to 60%, it goes to perfect zero. The only way the current will go up is if I do a very heavy CPU load. For this reason, I’m not sure it’s doing straight pass through — it must be some kind of hybrid design or something I don’t understand. If I leave it at the default 100% setting for a full charge, when I get to 100% it still runs about 2.2W idle in OpenBSD (1.6W in Linux), so the way the battery or system firmware works for 100% seems to be much different than for 60%. Maybe it’s just because of the voltage difference between the two maxes. I haven’t tested 99%, for example.

Do you have any insight into whether obsdfreqd has similar power saving to this patch? It seems to set the perf similarly. I wasn't having much luck with obsdfreqd as far as wattage, however... Nate

I am seeing a lot of power drawn even when nothing is going on on the system (top shows everything at zero, load average is 0.01). This is even if the backlight is dim. On an Ubuntu Linxu system, i was getting about 3.5-4W when nothing much was going on.
