cpuidle - control minimum idle time before getting into sleep ?

Hello,

I am using tickless kernel, and cpuidle using menu governer.
Is there a way to control minimum idle time before getting into sleep ?
I noticed that sometimes there is degredation in performance becuase
cpuidle gets into sleep.
I've noticed this behaviour with iperf bandwidth test with small packet only.

Is there a way to control the minimum time of idle before deciding of sleep.
I assume that if I have such control, I can enlarge this time, and so
the iperf bandwidth test with small packets shall never get into sleep
state.


Thank you!
