Research direction

Start by reproducing the command on a Raspberry Pi 3 and checking the kernel's CPU hotplug configuration and messages. The issue provides no file or test location, so trace the /sys/devices/system/cpu CPU-online handling and compare the observed behavior with supported Raspberry Pi kernel behavior. Done means establishing whether runtime CPU offlining is supported or identifying the configuration or failure involved.

Written by the indexing model from the issue text.

Description

I don't know if it's a misconfiguration of my kernel or if it's just not possible to ofline a cpu on the fly with the command:

echo 0 > /sys/devices/system/cpu/cpuX/online
