E-keying support in phase 2 (BMC and NPU cooperation)
If the NPU needs to perform any operation on board backplane interfaces, it should first
obtain the status of these interfaces from the BMC by sending a Get Port State or
Bus Resource Control command. If the BMC receives a Set Port State or
Bus Resource Control command from the ShMC, it generates an NPU interrupt and
the Boot Monitor configures the backplane interfaces accordingly.
Phase 3
In phase 3, the board is fully operational and running Linux. In this phase, the NPU is
running the BMC Agent application, which is able to receive E-Keying IPMI messages
from the BMC.
