Team,
I am looking for “fan speed control” feature to enable for Tiogapass. I understand that there are many approaches for this. Please point me to all implementation and any details about each approach, may be some pros and cons.

Regards
-Vijay

To my knowledge all recipes are here for fan control:

https://github.com/openbmc/meta-phosphor/tree/master/recipes-phosphor/fans

obmc-control-fan_git.bb - looks like a default fan speed script

obmc-phosphor-fand.bb

phosphor-fan_git.bb

phosphor-pid-control_git.bb

    obmc-control-fan_git.bb - looks like a default fan speed script
I don't see any source code for this.
    
    obmc-phosphor-fand.bb
And for this also I am not seeing anything other than a simple while loop in obmc-phosphor-fand.c. I might be missing src file.

Since you're using Entity-Manager, you might be interested in 
https://github.com/openbmc/phosphor-pid-control/blob/master/dbus/dbusconfiguration.cpp

apologize for the late reply, we are planning to write a document for
the fan configuration.

As James pointed out, there are 3 fan control applications where 2 are 
currently maintained repos.

obmc-control-fan_git.bb & obmc-phosphor-fand.bb
To my knowledge, these were the fan management reference implementations 
that are no longer maintained and/or supported.

https://github.com/openbmc/phosphor-pid-control
(This is a configurable PID based fan control application)

https://github.com/openbmc/phosphor-fan-presence
(This contains configurable fan presence, fan monitoring, and RPM/PWM 
fan control applications)

The doc draft that George referenced relates to the 
phosphor-fan-presence repo.

Presumably lm_sensors (recipe lmsensors in meta-oe) would work for this?

Are there any recipes compatible with generic_pc to allow the cpu and system fan speeds to be controlled?
