Hi All,
  I have some problems with phosphor-hwmon. 
Could package phosphor-hwmon supports peci sensors such as cpu and dimm tempatures ? 
If yes, could you give me some hints that how do I write configuration for peci sensors, please :). 

Duke, Du

phosphor-hwmon should work with anything that implements the hwmon ABI.  
So I think to make PECI sensors work with phosphor-hwmon, you need hwmon 
drivers for PECI sensors.  I don't know if anyone is working on that.

I suspect the other sensor application - dbus-sensors supports PECI 
just fine.  But I don't know how it works, if it can be used without 
entity manager,  and/or if it can be run in parallel with

CPU sensor currently supports PECI sensors

It does require entity-manager currently, but it could be run in 
parallel with phosphor-hwmon.
