Hi Stratos,
Yes, your results show some improvements. BUT if performance is the only
thing
we were looking for, then we will never use ondemand governor but
performance
governor.
I suspect this little increase in performance must have increased power
numbers
too (significantly). So, if you can get numbers in the form of
power/performance
with and without your patch, it will be great.

I run some more tests. I increased the number of iterations to 100 (from
20).
I also test for counter 1,000,000 (~4200us), 5,000,000 (~10000us),
15,000,000 (~30000us).
This time, I also extracted statistics from cpufreq_stats driver. I think
this will be an
indication for power consumption. Below the results and attached the
program I used for to
get these numbers.
Any comments would be appreciated.
Sorry, i forgot about this mail earlier..
Your performance numbers look improved but i am still not sure about
power consumption. But as this is not going to be the default settings, i
think we can take this patch.

Hi Rafael,
I'm sorry for bothering you again for this patch.
Are these number adequate? Should I provide more benchmark results?
Thanks for your time.
