[igt-dev] [PATCH i-g-t] i915/gem_exec_suspend: Measure power consumption during suspend

[Chris Wilson]

For this test, we need a laptop running on battery power so that we can
read the battery charge level before and after suspend. And then wait
long enough for a reliable measure.

As you said, this is quite a long time. Even with the suspend and modern
laptop it should show meaningful data quicker. But we need moar
data on multiple specimens to find a good spot.

I dunno what is the go-to unit in here, but mA would be
as comparable and time independant. Perhaps show both.

There are lot of potential in here to automate against pm
regressions. Plugging this into the apc and gathering
baseline consumptions.


This is a neat start and I aimed at t-b too.
Didn't happen so I can offer only,

/sys/devices/power_supply/BAT0/ gives mWh and voltage iirc. I went with
mWh/mW as that seems the easiest with less modelling required.

Yup, fingers crossed that may happen. :)
