Sudo dpkg reconfigure nvidia-l4t-bootloader cannot be used when Jetson Xavier updates sudo dpkg reconfigure nvidia-l4t-bootloader

I would like to teach you a question. Linux system wants to get the temperature and resource utilization rate of GPU in its own application program in real time. What library can I use for programming language c + +?

The NVIDIA Management Library (NVML) is the basis of the nvidia-smi utility and gives you access to the same information that is displayed by nvidia-smi:
