TX1 To force those A57 cores running

Hi dusty_nv
Refer to this article
https://devtalk.nvidia.com/default/topic/1006937/?comment=5140050
TX1 supports 4 A57 cores and 4 A53 cores, can all of these cores run at the same time? or when A57 cores running,then A53 cores stop or power off ? and vise versa?
