5 Power Management Strategies
13 The Linux kernel supports two major high-level power management strategies.
15 One of them is based on using global low-power states of the whole system in
16 which user space code cannot be executed and the overall system activity is
17 significantly reduced, referred to as :doc:`sleep states <sleep-states>`. The
18 kernel puts the system into one of these states when requested by user space
19 and the system stays in it until a special signal is received from one of
21 user space code can run. Because sleep states are global and the whole system
