Subject: Power saving in case of CPU hotplugin
Date: Wed, 7 Sep 2016 14:31:46 +0530	[thread overview]
Message-ID: <CAGrgb4USuXpFaRO0aLZuQ4o0MFjWBesktCSctn6PPWS9+cWM+A@mail.gmail.com> (raw)

HEllo all,

I was going through a linux well known concept, hot plugin of cpu cores:
https://www.kernel.org/doc/Documentation/cpu-hotplug.txt

Is it more power saving than highest C-State and P-State?

If we make one cpu offline, it disappears from the OS as it is not present,
Is that means that CPU is powered off?

Thanks,
Debdipta
