Hi,

I wanted to know if the ondemand governor scales down the frequency to a minimum when the load comes below up_threshold?

I understand that

1. Every now and then, the governor work queue runs and checks for

"load" in percentage.

If load > 95 ; it bumps the frequency to maximum;

ie. if the idle time is less than 5% ; the cpu will run at maximum

2. If load < 90% ; it bumps the frequency down little bit;

   It continues to do this till minimum; So the rate of decrease of

frequency to minimum is very slow;

So, the frequency decrease to minimum will take a long time to reach minimum (depends on sampling time).

Is this correct.

Latest ondemand gov keeps freq proportional to load all the time.. and switches to max freq directly if load is over 95..
