02:21 <macromorgan> anyone on here familiar with fuel gauges? I'm trying to write a driver and I have a few questions, like... should the POWER_SUPPLY_PROP_VOLTAGE report the average voltage of the battery (4.1v max, 3.5v min), or should it report 4.1v when charging and 3.7v when not?

12:27 <broonie> macromorgan: If you can't measure it should you be reporting it at all?

13:40 <macromorgan> I can measure it, but I think I'm not exactly measuring the battery. Is there some sort of a driver guide for what I should support with the battery gauge driver at a minimum? I didn't find anything in the documentation.

13:41 <macromorgan> basically my battery voltage is coming back at 4.2v roughly while charging, but 3.7v while discharging... I'm thinking it's something like sys voltage instead

15:58 <macromorgan> think I figured it out, just need to know what to report. I have a "BAT_VOL" which measures the voltage pushed to/pulled through the battery... basically a constant 3.7v when running off the battery and a charging voltage of 4.1v when charging. I also have an OCV voltage which appears to be the internal voltage of the battery (starts around 4.1v and goes down based on charge level).

15:59 <macromorgan> would the OCV voltage be POWER_SUPPLY_PROP_VOLTAGE_NOW (since that's the actual voltage of the battery), or should I report the battery voltage as that and the OCV voltage as POWER_SUPPLY_PROP_VOLTAGE_OCV?

20:17 <ukleinek> when compiling allmodconfig for arm64 on 5.14-rc1 I get: https://paste.debian.net/1204276/

20:17 <ukleinek> Is it only me?

20:58 <milkylainen_> ukleinek: Compiler optimization error?

21:00 <milkylainen_> ukleinek: nevermind.
