I think you have Srivatsa there who has seen lots of cpufreq code and
could have helped you a lot :)
:-)
I was waiting for your reply here :)
I have followed the locking and synchronization aspects of cpufreq

Ok, I had based my code on linus's git tree. I checked the 'pm-cpufreq'
Always check his bleeding-edge or linux-next branch.

Yeah, I had the driver written using driver_data to store pstates.
Gautham found the bug that we are missing one PState when we match the
ID with CPUFREQ_BOOST_FREQ!
I see..
We did not know that you have taken

Will fix the code to take care of this.

Backend driver to dynamically set voltage and frequency on
IBM POWER non-virtualized platforms. Power management SPRs
are used to set the required PState.
This driver works in conjunction with cpufreq governors
like 'ondemand' to provide a
