openBMC pwm-fan control policy

[Landon]

add: I just want to know in OpenBMC by reading different temperature values or current values to control the fan output, so as to cool down, how does this strategy work? An example of this.



Thanks!

hello, paul


Thank you for your reply!

I've read the "phosphor-pid-control ".
But I didn't read about the linked between temperature and current.

could you give me an example?



Thanks!

Are there any instructions or references?

https://github.com/openbmc/phosphor-pid-control should be flexible
enough for the purpose. Is it missing something you need?
