Hi there,
I am trying to implement cpuidle driver for imx51, and for better
understanding how various c-state map to ARM soc,
I would like to get some comments.
First of all, we basically have 3 major state for imx51, which are defined
in specification of the soc. Like:
RUN - Core is active,
Yong,
Idea of defining various C states is to get maximum power savings both
active and inactive usecases.
C states you defined below are definitely good as a starting point.
May be you can define more C states by adding more granularity
depending on what are controlled as part of CPUIdle.
Eg: In

this one feels odd as beagle is omap3
That's actually correct; omap2plus is meant to support OMAP2, OMAP3 and
OMAP4 in the same binary kernel (OMAP2+)

When booting linaro snapshots on my PandaBoard the system hangs a few seconds

already powered off - very strange. I've tried
Please help me figuring out the problem. Is it because I didn't create

I believe you're right.

Hi Avik,
Would you be willing to try the instructions I created for this at:
