Regarding the frequent printing of CPU throttling alerts in the dmesg of Xavier

Jetpack Version: JP5.1.1
Hardware Version: AGX Xavier

Hi Nvidia,

After upgrading Xavier to JP5.1.1, I noticed that the CPU frequently prints the alerts shown in the image below in the system dmesg after reaching 65 degrees. The frequency of these prints is quite high. Additionally, I found the source of the log prints in the code snippet below, but I cannot understand why it switches states frequently. From a code perspective, high temperature implies an anomaly, and the state transitions from 0 to 1 are understandable and acceptable to me. However, why is it immediately printing 1 to 0 afterward? This truly baffles me. Could you provide insight into the reason behind this? Do you have any suggestions?

Are you sure you also observe same issue when it is on NV devkit?

We don’t have any default setting to do cpu software throttle when temperature is in 65C.

Hi, WayneWWW

During my testing, I observed that actual throttling behavior occurs at 90 degrees, but the printing of this log continues to appear frequently. I’m curious about Nvidia’s strategy in this regard. Is there any documentation or resource where I can find more information? Alternatively, could you provide a detailed explanation?

Best regards

Hi,

Document is over here.
https://docs.nvidia.com/jetson/archives/r35.5.0/DeveloperGuide/SD/PlatformPowerAndPerformance.html?highlight=power%20consumption

Basically you should try to clarify whether this is only from your carrier board or even the NV devkit could hit same issue.

We don’t really comment on a custom board behavior as the thermal solution on it is customized by you

Hi

I’m glad to hear that you found the document helpful! If you have any further questions or need assistance, feel free to reach out. I’m here to help!
