Power Consumption (INA) Monitors of Xavier Board

Hi,
I need to read the GPU and DRAM power consumption of Xavier board, and based on this link https://developer.nvidia.com/embedded/jetson-agx-xavier-dl-inference-benchmarks , it seems that Xavier also has the INA monitors similar to TX2, however, I couldn’t find the input power file in sys directory of Linux. Here is the content of NVIDIA Tegra release:

nvidia@TeCSAR-Xavier1:~$ head -1 /etc/nv_tegra_release

R31 (release), REVISION: 0.2, GCID: 12860113, BOARD: t186ref, EABI: aarch64, DATE: Sat Sep 29 05:14:38 UTC 2018

Hi mrb256, please refer to Chapter 5 of the Jetson AGX Xavier Thermal Design Guide for the commands to read the INA sensors.
