Hi, everyone
In my system, NMI intrrupt counter is increased continuously, which I found in /proc/interrupts. How can I find the reasons of NMI interrupts? How fast are they increasing? A few an hour? A few a minute? once per second... and I found the nmi couter is same with PMI.
What does 'grep -i nmi your-config-here' return?
My kernel config about NMI is as follows : CONFIG_DEBUG_NMI_TIMEOUT=5 CONFIG_HAVE_FTRACE_NMI_ENTER=y CONFIG_FTRACE_NMI_ENTER=y Thanks
