Help¶

This option enables the kernel to interface with a power manager application. This permits the system to enter a Deep sleep state supported by the SOC where the system clock is turned off while RAM is retained. This state would be entered when the kernel becomes idle for extended periods and would have a high wake latency. Resume would be from the reset vector same as cold boot. The interface allows restoration of states that were saved at the time of suspend.
