Hi,
A Non-Maskable Interrupt (NMI) is a hardware interrupt that cannot be ignored by the processor. These types of interrupts are usually reserved for very important tasks and to report hardware errors to the processor.
Depending on the make and model of the system, you may be able to deliberately send an NMI to the CPUs. By sending an NMI to the processor, it is forced to switch CPU context to the registered non-maskable interrupt handler. The interrupt cannot be ignored (masked). The operating system can handle the NMI based on prior configuration.
