Below are the list of questions

Questions:-

2) How Android Power Management differ from the Linux Power Management?
3) Is there any source-code difference b/w Android Kernel and Linux Kernel? 
What are the changes Google made in Kernel for Android Power Management?
4) Android maintain its own git branch for Kernel Code and it is different 
from the Linux mainline Kernel Code branch; What is the reason behind this 
different kernel maintenance?

   Linux Mainline Kernal Source Link:- https://www.kernel.org 

5) Please provide me all the details regarding changes/patch made by Google

[android-developers] Android Power Management

[Prashant Bhujang]

Dear All,

Android has provided Power management framework for saving batterlife. But this 
is limited to screen/key lights. I am exploring ways to enhance this scheme for 
other use cases like camera, media playback by changing CPU frequency. I would 
like to know what support is available for this from Android kernel.

[android-developers] Android power management

[Yuchih]

I have recently seen the Google I/O session: Anatomy  Physiology of
an Android.
Patrick Brady mentioned power management in Android, and I am highly
interested in it.

But I have a question that what is more aggressive power management
policy?
What is the different between the Android and Linux default one?
Does that mean if I don't use partial/full weak lock, even the CPU is
running, Android will also put the CPU to lower frequency then to idle
state?
Does the current kernel patch have the behavior to do that?

I need some detail information about it.
Hope somebody could help me.
Thanks very much!

Best Regards,
Yuchih
