22.13.1 Signal Generation
The BMC generates an NMI pulse under certain conditions. The BMC-generated NMI pulse
duration is at least 30 ms. Once an NMI has been generated by the BMC, the BMC does not
generate another until the system has been reset or powered down, unless an NMI Enable /
Disable command is used to re-arm the NMI.
The BMC captures the NMI source(s) and makes that information available via a Get NMI
Source command. Reading the NMI source information clears the information. The Set NMI
Source command is available to other agents, such as the BIOS SMI handler, to register NMI
sources when they detect NMI-generating errors. Operating system NMI handlers that save the
system crash state can use the Get NMI Source command to determine and save the cause of
the NMI.
The NMI Enable / Disable command disables BMC NMI generation. The default state is
enabled. The enabled / disabled state is volatile; it is not saved across AC power cycles.
The following cause the BMC to generate an NMI pulse:
 Receiving a Chassis Control command to pulse the diagnostic interrupt. This command
does not cause an event to be logged in the SEL.
 Detecting that the front panel diagnostic interrupt button has been pressed. See section
22.6.4.3.
 A PEF table entry matching an event where the filter entry has the diagnostic interrupt
action indicated.
 Watchdog timer pre-timeout expiration with NMI / diagnostic interrupt pre-timeout action
enabled.
 A Set NMI Source command issued from a command interface.
The following table shows behavior regarding NMI signal generation and event logging by the
BMC.
