I am seeing a lot of post here about the AGX power usage stats available in the tegrastats output, as well as accessible under sysfs. There seems to be conflicting responses to this question about calculating the actual power usage of the AGX SOM as well as the power usage of the AGX and Nvidia carrier card.
Can you provide an answer on exactly what values need to be summed together to get the AGX SOM power usage and if it is also possible to determine the overall AGX+carrier card power?
I see the following power measurement entries:
As for the overall AGX+carrier card power, I looked through the document Jetson_AGX_Xavier_Developer_Kit_Carrier_Board_Specification_SP-09778-001_v2.1.pdf but did not any power sensors I can access, for example over the I2C bus.
