我们从系统中的thermal-zones.YAML文件中，看到了一些 CPU和GPU的配置，感觉不太正常，没有体现 active,passive,hot,critical等全面的温度控制。但实际高温测试中发现风扇的PWM、CPU主频等都会发生变化，和thermal zone里面的不一致。请帮忙确认这个文件是否正确，我们应该从哪个路径下查到正确的热区信息。

Based on the provided context, I will provide a comprehensive answer to the question.
The question seems to be asking about the thermal management features of the Jetson AGX Orin, specifically about the thermal zones, CPU and GPU temperatures, and power modes.
According to the provided context, the Jetson AGX Orin has several thermal management features, including:
- Thermal zones: The Jetson AGX Orin has multiple thermal zones, which are defined in the
thermal_zones.yamlfile. These zones include the CPU, GPU, and other components. - CPU and GPU temperatures: The Jetson AGX Orin has temperature sensors for the CPU and GPU, which can be monitored and controlled using the
nvpmodeltool. - Power modes: The Jetson AGX Orin has multiple power modes, which can be selected using the
nvpmodeltool. These power modes determine the maximum frequency of the CPU and GPU, as well as the number of CPU cores used.
The provided context also mentions the nvpmodel.conf file, which contains the power mode details for the device.
In comparison to other Jetson modules, the Jetson AGX Orin has similar thermal management features, but with some differences in terms of the specific thermal zones and power modes supported.
For example, the Jetson Orin NX and Jetson Orin Nano also have thermal management features, including thermal zones and power modes, but the specific details may differ from those of the Jetson AGX Orin.
In terms of the specific question about the thermal zones YAML file, it is likely that the file contains information about the thermal zones on the Jetson AGX Orin, including the temperature ranges and thresholds for each zone. However, without more information, it is difficult to provide a more detailed answer.
Overall, the Jetson AGX Orin has robust thermal management features, including thermal zones, CPU and GPU temperature monitoring, and power modes, which can be used to optimize the performance and power efficiency of the device.

我们抓了串口log的系统打印信息，有如下信息。
发现thermal cooling_device12: hot-surface-alert 每秒切换一次状态，但我们上面的热区里设置的滞回空间是8℃，按说不应该有这么快的状态切换呀，可以解释一下吗

這裡澄清一下, thermal-zones.yaml 只是Linux kernel提供的範例文件.
我們的thermal zone並沒有照上面的設計
詳細thermal 文件可以參考各Jetpack版本的 developer guide.
hot-surface-alert 目前沒有做hysteresis的設定. 所以你看到那個現象是預期的
: hot-surface-alert cooling state在log會一直跳動.
