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 mainline?
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 bye, Heiko
