Regarding Power Management

Hello All,
I am working on a ARM based development board. I have a power management dr=
iver which implements the basic power frame work (Power controller) and the=
Resource Manager.

Just wanted to ask that do I need to write any plugin or adaptation layer s=
o that User Side code can call this module to go into IDLE or SLEEP mode?=

Thanks,

Hi,

In any power model, the user-side has an essential role. It is important th=
at applications that need to know about changes to the power state are info=
rmed. Just as important, the user-side can request changes to the power sta=
te of individual peripherals (indirectly), and the whole device, usually On=
, Off and Standby.

The kernel side code determines when / if the core goes into the various id=
le or sleep modes.

Hello Mark,
Thanks a lot for taking your time out and responding.
As you said, user side code can request changes to power state of individua=
l peripehral. Now, my question is that How would user side code request tho=
se changes? I mean through any plugin or adaptation layer? For example deco=
ded sound data goes to sound driver through DevSound Layer. Do I need to wr=
ite any such thing?
Or, If I have implemented the Power Controller and Resource Manager in my p=
ower managment module, that should suffice?
