Hello Experts,

For one of our requirement we need to service the NMI interrupt on a GPIO line. Whenever the GPIO line is asserted the NMI service routine should reset the CPU. But as per my understanding the UEFI does not support interrupts, the drivers are serviced by polling.  Can you please suggest how to go about this?

 

Thanks,

Raghu
