Hi,

 I am using i.MX6Q SABRE SD with linux 3.18.29 kernel. I ran the following script on it with two different

frequencies -> 996000 and 792000

 

I ran the following script:

 

while :

do

expr 88888888888888 \* 77777777777777777

done

 

The %CPU used is ~ 30% with both the frequencies. How is this calculated?
