You might be interested in bug 769431 where Intel modified power gadget to
export symbols that the profiler can use to sample the power state and
correlate it with execution.

I am working on using intel power gadget to measure the power usage. Currently
this is on windows with an idle test. Our test slaves have older CPUs which do

Good point. Just accessing the battery level is rather imprecise, but
Telemetry + large numbers should help us see trends.

possibly a few utility functions in e.g. Telemetry or TelemetryStopwatch.
Cheers,

So, here are my questions:
- do we already have a good way to measure power usage by some thread
between two points in time?
- if not, would there be interest in developing a li
