The power sensors can be configured to sample the readout values over time. Nvidia does this too, so nouveau should probably do that too.

This is a complete rework from the first version I sent out. Now the implementation is more centered around the power_rails we find in the SENSE table instead of extdev centered. This makes the implementation a lot easier and straightforward. I've added support for the INA219, INA209 and INA3221 sensors found on multiple Fermi and Kepler cards. The power consumption is also exported via
