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. 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
