E-keying support in phase 3 (BMC and NPU cooperation)
In the Linux startup phase, the NPU BMC Agent application configures all board
backplane interfaces according to information received from the BMC. During normal
Linux operation, the BMC updates the E-Keying Status Word according to commands
received from the ShMC and forwards these as Set Port State and
Bus Resource Control commands to the NPU BMC Agent, which is responsible for
handling these commands. See
E-Keying Status Word
The E-Keying Status Word contains information about the current state of all board
backplane interfaces. This status word is maintained by the BMC and stored in a BMC
EEPROM, since the state of backplane interfaces must not change during accidental
BMC reset.
The E-Keying Status Word is used internally by the BMC. It is not accessible to external
applications.
