Hi Team,

I am working to include the sensors from the FRU (HOST), The fru
communication is through ipmb.

I tried by adding all the sensor address and limits details in the JSON
file and get the sensor details under IPMBSensor using entity manager.

It looks more static and now i wanted it to be added dynamically using SDR
commands.

The following are the SDR commands supported by FRU and using this we can
dynamically get the sensor list and include the sensors.

*Command*

*NetFn*

*CMD*

Get SDR Repository Info

Storage

20h

Reserve SDR Repository

Storage

21h

Get SDR

Storage

23h


Is there an implementation already exists to handle SDRs for ipmbbased FRUs?

Please let me know your thoughts/inputs



Thanks,

Sathish S.

I don't believe IPMBDevice supports this dynamic discovery of sensors
today;  What's there is largely implemented to work with Management
engine, and its set of I2C commands.  SDR parsing and introspection
would need to be added.  I'm happy to help review if you want to put
together an implementation that does this.
