HI,
I am working on optimizing the power consumption on the system.
I need to detect when the system is idle and move it to standby state.

cat /sys/power/state

and an

And when there is an interrupt, it needs to be brought back to run state.

I have an application which is waiting on a message. When it gets idle message, it needs to move the system to idle state.
I have two questions:
1. How do we detect the idle mode.
2. Can I call the acpi_suspend() function from my driver to move the system to different states. If not what is the preferred way.
Sridhar.
