4 NMI sourcing for iLO based ProLiant Servers
8 The HPE iLO NMI Watchdog driver is a kernel module that provides basic
9 watchdog functionality and the added benefit of NMI sourcing. Both the
10 watchdog functionality and the NMI sourcing capability need to be enabled
12 A user can have the NMI sourcing without the watchdog timer and vice-versa.
28 allow_kdump - allows the user to save off a kernel dump image after an NMI.
40 The NMI sourcing capability is disabled by default due to the inability to
