-A device is always in the highest power state which satisfies its driver,
-its policy-maker, and any power children it has, but within the constraint
-of the power state provided by its parent. The driver expresses its desire by
-calling changePowerStateTo(), the policy-maker expresses its desire by calling
-changePowerStateToPriv(), and the children express their desires by calling
-requestPowerDomainState().
-
-The Root Power Domain owns the policy for idle and demand sleep for the system.
-It is a power-managed IOService just like the others in the system.
-It implements several power states which map to what we see as Sleep and On.
-
-The sleep policy is as follows:
-1. Sleep is prevented if the case is open so that nobody will think the machine
- is off and plug/unplug cards.
-2. Sleep is prevented if the sleep timeout slider in the prefs panel is zero.
-3. System cannot Sleep if some object in the tree is in a power state marked
- kIOPMPreventSystemSleep.
-
-These three conditions are enforced using the "driver clamp" by calling
-changePowerStateTo(). For example, if the case is opened,
-changePowerStateTo(ON_STATE) is called to hold the system on regardless
-of the desires of the children of the root or the state of the other clamp.
-
-Demand Sleep is initiated by pressing the front panel power button, closing
-the clamshell, or selecting the menu item. In this case the root's parent
-actually initiates the power state change so that the root domain has no
-choice and does not give applications the opportunity to veto the change.
-
-Idle Sleep occurs if no objects in the tree are in a state marked
-kIOPMPreventIdleSleep. When this is true, the root's children are not holding
-the root on, so it sets the "policy-maker clamp" by calling
-changePowerStateToPriv(ON_STATE) to hold itself on until the sleep timer expires.
-This timer is set for the difference between the sleep timeout slider and the
-display dim timeout slider. When the timer expires, it releases its clamp and
-now nothing is holding it awake, so it falls asleep.
-
-Demand sleep is prevented when the system is booting. When preferences are
-transmitted by the loginwindow at the end of boot, a flag is cleared,
-and this allows subsequent Demand Sleep.
+A device is always in the highest power state which satisfies its driver, its policy-maker, and any power domain
+children it has, but within the constraint of the power state provided by its parent. The driver expresses its desire by
+calling changePowerStateTo(), the policy-maker expresses its desire by calling changePowerStateToPriv(), and the children
+express their desires by calling requestPowerDomainState().
+
+The Root Power Domain owns the policy for idle and demand sleep and doze for the system. It is a power-managed IOService just
+like the others in the system. It implements several power states which correspond to what we see as Sleep, Doze, etc.
+
+The sleep/doze policy is as follows:
+Sleep and Doze are prevented if the case is open so that nobody will think the machine is off and plug/unplug cards.
+Sleep and Doze are prevented if the sleep timeout slider in the preferences panel is at zero.
+The system cannot Sleep, but can Doze if some object in the tree is in a power state marked kIOPMPreventSystemSleep.
+
+These three conditions are enforced using the "driver clamp" by calling changePowerStateTo(). For example, if the case is
+opened, changePowerStateTo(ON_STATE) is called to hold the system on regardless of the desires of the children of the root or
+the state of the other clamp.
+
+Demand Sleep/Doze is initiated by pressing the front panel power button, closing the clamshell, or selecting the menu item.
+In this case the root's parent actually initiates the power state change so that the root has no choice and does not give
+applications the opportunity to veto the change.
+
+Idle Sleep/Doze occurs if no objects in the tree are in a state marked kIOPMPreventIdleSleep. When this is true, the root's
+children are not holding the root on, so it sets the "policy-maker clamp" by calling changePowerStateToPriv(ON_STATE)
+to hold itself on until the sleep timer expires. This timer is set for the difference between the sleep timeout slider and
+the larger of the display dim timeout slider and the disk spindown timeout slider in the Preferences panel. For example, if
+the system is set to sleep after thirty idle minutes, and the display and disk are set to sleep after five idle minutes,
+when there is no longer an object in the tree holding the system out of Idle Sleep (via kIOPMPreventIdleSleep), the root
+sets its timer for 25 minutes (30 - 5). When the timer expires, it releases its clamp and now nothing is holding it awake,
+so it falls asleep.
+
+Demand sleep is prevented when the system is booting. When preferences are transmitted by the loginwindow at the end of
+boot, a flag is cleared, and this allows subsequent Demand Sleep.
+
+The system will not Sleep, but will Doze if some object calls setSleepSupported(kPCICantSleep) during a power change to the sleep state (this can be done by the PCI Aux Power Supply drivers, Slots99, MacRISC299, etc.). This is not enforced with
+a clamp, but sets a flag which is noticed before actually sleeping the kernel. If the flag is set, the root steps up
+one power state from Sleep to Doze, and any objects in the tree for which this is relevent will act appropriately (USB and
+ADB will turn on again so that they can wake the system out of Doze (keyboard/mouse activity will cause the Display Wrangler
+to be tickled)).
