Broadcast get device ID command
This command is available to MC, ChMC, and PSMC. It is only relevant to satellite controllers.
This command is the broadcast version of the get device ID command which provides for the
discovery of intelligent devices on the IPMB only. Request is formatted as an entire IPMB application
request message, from the RsSA field through the second checksum, with the message prefixed
with the broadcast slave address, 00h. Response format is same as the regular get device ID
response.
The broadcast get device ID command is not bridged but can be delivered to the IPMB
using master write-read commands.
To perform a discovery, the command is repeatedly broadcast with a different rsSA slave address
parameter field specified in the command. The device that has the matching physical slave address
information shall respond with the same data it would return from a regular (non-broadcast) get
device ID command. Since an IPMB response message carries the responder’s slave address,
the response to the broadcast provides a positive confirmation that an intelligent device exists at
the slave address given by the rsSA field in the request.
An application driving discovery then cycles through the possible range of IPMB device slave
addresses to find the population of intelligent devices on the IPMB.
