howto: imx8mp handle shutdown

[Ralf_Rademacher]

i want to shutdown my system on POWER_KEY event.

but i recognized that there was a patch from nxp called: 0020-logind.conf-Set-HandlePowerKey-to-ignore.patch 

Subject: [PATCH] logind.conf: Set HandlePowerKey to ignore

For i.MX, we don't want systemd to handle the power key.

what is the correct way to shutdown instead?

i tried HandlePowerKey=poweroff, what worked as expected, but if there is a better way, please let me know.

Best regards

Ralf

Hello,

I think systemd shutting down the system is the best solution to make sure that the software components are all terminated properly without causing additional problems.

Thank you very much for your answer!

Did I understand you correctly that the best way would be to set HandlePowerKey=poweroff in logind.conf?


Many thanks in advance

Hello,

Yes. If you are shutting down normally, use systemd; if you need to force a shutdown and don't care if the runtime data is intact, consider shutting down using the hardware key associated with pmic.
