Maybe not sure. I have had such code in the past and it was quite

The cpu idle cooling driver performs synchronized idle injection across all
cpus belonging to the same cluster and offers a new method to cool down a SoC.
Each cluster has its own idle cooling device, each core has its own idle
injection thread, each idle injection thread uses play_idle to enter i
