Diagnostic Interrupt
The following command provides the capability for an end user to issue a non-maskable
interrupt (NMI) to the payload.
When issued, the NMI signal to the processor is asserted. To fully utilize the support of
this command, the user needs to have an NMI handler installed.
The implementation details are shown in
Diagnostic interrupt command implementation
The sequence of actions is as follows:
OEM IPMI Commands
This section documents the OEM style IPMI commands implemented and supported on
