[Question] Temperature Sensors API call fails in non-privilege mode.

[Sarbojit2019]

I am trying to get GPU temperature information for my tool. It seems Temperature Sensor APIs need to be queried only in privilege mode. Users of my tool may not have 'sudo' access on all the systems hence the question.

Questions:

1. I can understand of SET APIs require 'sudo' access or privilege mode but why do we need to be in privilege mode for query?
2. Is there any other way to query GPU temperature?

Any suggestion will highly appreciated.
