Thermalzone group

Hi, Im sjkim.
I am using ‘Jetson Power GUI’ tool on jetson orin-nx platform.
but, I have questions in Thermalzone part.

Could you explain the meaning behind the names of these sensors and how CV0, CV1, and CV2 differ from each other? Also, how do SoC0, SoC1, and SoC2 differ from one another? and CPU,GPU, tj?

Hi sjkim16,

What’s your Jetpack version in use?

Have you referred to the instruction in Thermal Management for those items?

Jetpack version : 36.3.0-20240506102626

Yes, i referred to the instruction in Jetson Orin Nano Series, Jetson Orin NX Series and Jetson AGX Orin Series — NVIDIA Jetson Linux Developer Guide 1 documentation.

But, I can`t find any information.

  1. CV0,CV1,CV2 Hardware area differ?
  2. SoC0,SoC1,SoC2 Hardware area differ?
  3. What are the conditions for sharing?

I don’t understand ex) ‘Center of CV0’, ‘Center of CV1’ …

Sorry for the late reply, I’ve checked these with internal.
Please refer to the following:

CV0 thermal bjts are put near by DLA0
CV1 thermal bjts are put near by DLA1
CV2 thermal bjts are put near by PVA
SOC0 thermal bjts are put near by DISPLAY, NVDEC, MGBE
SOC1 thermal bjts are put near by PCIE, ISP, NVENC
SOC2 thermal bjts are put near by ADSP, OFA

Thank you, KevinFFF.
It helped a lot.
