Hi,

I am using a arm based muticore platform.

I intend to call hibernate from a push button interrupt. I have
initialized a workqueue for calling hibernate() and have scheduled it
in the push button interrupt service routine. I have chosen workqueue
over tasklet for the reason:-
1. Workqueue gets called in process context whereas tasklet gets
called in deferred interrupt context and thus as hibernate is a long
process (which can sleep) , I found workqueue to be more suitable.

My query is that does the function added in workqueue get executed on
a  different core than from where it gets scheduled. In my case, it
would be a major issue as hibernate() is expected to get called from
core0 only.

have you tried

queue_work_on?

If so, what is the possible remedy to suffice my need. I understand
that workqueue cannot be assigned to a particular core.

Please correct me if my understanding is incorrect.

Regards,
Ayan Kumar Halder
