If an interrupt is raised while the CPU executes in user space, the entry and exit handling is exactly the same as for syscalls. If the interrupt is raised while the CPU executes in kernel space the entry and exit handling is slightly different.

WebA Thread • Thread attributes – processor related • memory PC • program counter CPU Code Memory • stackpointer • registers(and status) – OS/package related • state (running/blocked) WebThe do_nmi() function processes each NMI. It first disables preemption in the same way that a hardware irq would, then increments the per-CPU count of NMIs. It then invokes the NMI handler stored in the nmi_callback function pointer. If this handler returns zero, do_nmi() invokes the default_do_nmi() function to handle a machine-specific NMI. department of finance probity
