Function Documentation

void cpu_enter_sleep

(

void

)

[inline, static]

Enter the deepest possible sleep mode.

Todo:

Currently, this function does nothing. We probably want to at least enter Idle mode when the workqueue is empty.

This function will determine the lowest possible sleep mode that can safely be entered, enable interrupts and put the chip into that sleep mode. This will all happen atomically, so no interrupts will be handled before the sleep instruction has been executed.

Todo:

Currently, no sleep modes deeper than Idle will be entered. Deeper sleep modes will require a proper sleep manager to be implemented and supported by all drivers.

Precondition:

Interrupts are disabled

Postcondition:

Interrupts are enabled
