20 Local power states describe power states for an individual node, and composite
21 power states describe the combined power states for an individual node and its
24 Entry into low-power states for a topology node above the core level requires
40 states, and chooses the deepest power state for a topology node that can be
49 states, and may request for a topology node to enter a low-power state when
62 power states, and doesn't account for composite power states that are shared
