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
