When I run tegrastats using a 1 min interval, I find that it shows some power to GPU sometimes even though I am not running anything.
CPU always has some power consumption value which is understandable as it is running OS processes. But why would GPU show power at some random time?
Tegrastat while Running nothing:
GPU utilization zero but GPU is reporting some power consumption.
RAM 3600/15699MB (lfb 923x4MB) CPU [1%@1190,0%@1190,0%@1190,0%@1190,1%@1190,0%@1190,0%@1190,0%@1190] EMC_FREQ 0% GR3D_FREQ 0% AO@39.5C GPU@40C Tboard@40C Tdiode@41.75C AUX@40C CPU@40.5C firstname.lastname@example.orgC PMIC@100C -----GPU 155/8------ CPU 465/465 SOC 931/784 CV 0/0 VDDRQ 0/0 SYS5V 1574/1421
What is the reason for that, how can I address this random overhead while trying to measure energy consumption caused by an application that I am running?
The DLA and Vision processor ne the other hand, do not show any such behavior.
