CPU isolation question again

[Luming Yu]

Hi there,

I noticed some discussion about CPU isolation which points me to the
patch set (https://lkml.org/lkml/2011/8/15/245). I'm currently
preparing a RFC-patch-set to automatically pick up a few suitable CPUs
to isolate then kick them out of service for a while. We need to
balance between  thermal & power management And overall system
performance during this operation as much as possible. So
software-cpu-online-offline interface could not be a good option to
me. But to make sure I'm not blindly running on a dead-end path, I'd
check with experts here to ensure it makes some sense to isolate CPUs
to this level, and the idea also makes some sense, and the most
important is it's not implemented yet.

Thanks!!
