How to issue shutdown from within a driver

NTDEV
1

I have a device driver that gets an interrupt when an external power supply is shutting down. While servicing that interrupt I need to shutdown the system as quickly as possible.
How can this be done???

Shutdown needs to be done from user space. Any shutdown mechanism from the
kernel has the problem, that the user and the applications are not informed
of the failure so cannot shutdown cleanly. Consider using a service
notified by the driver, which then uses the standard API’s for shutdown from
user space.

Design your device as a battery and use the standard OS features used by
laptops.
