Hello all,

is it possible to reboot current mainline kernel triggered from a
GPIO in kernel space?

If not, how can be done this, so that it has a chance to go into

Your GPIO could (should) be bound to a gpio-keys driver which will deliver key presses event; which you can ultimately bind to the action of triggering a system reboot.

Granted, this makes you cross a lot of layers, and requires user-space to implemnt the reboot policy, but what you are asking for is both a mechanism and policy mix, which is usually not accepted.

You are probably working with HW which won't change, but wiring a reset button to a system reset output is usually much simpler ;)

Thanks for any suggestions
