     * cpufreq parameters. This function may also call the

     * appropriate interfaces to allow the kernel to suspend the

     * system to low-power sleep state when entering non-interactive

     * state, and to disallow low-power suspend when the system is in

     * interactive state. When low-power suspend state is allowed, the

     * kernel may suspend the system whenever no wakelocks are held.

     *

     * For example,

     * This function can be called to enter non-interactive state after

     * turning off the screen (if present) and called to enter

     * interactive state prior to turning on the screen.
