+affects this flag. The "power.wakeup" field is a pointer to an object of type
+struct wakeup_source used for controlling whether or not the device should use
+its system wakeup mechanism and for notifying the PM core of system wakeup
+events signaled by the device. This object is only present for wakeup-capable
+devices (i.e. devices whose "can_wakeup" flags are set) and is created (or
+removed) by device_set_wakeup_capable().
Whether or not a device is capable of issuing wakeup events is a hardware
matter, and the kernel is responsible for keeping track of it. By contrast,
whether or not a wakeup-capable device should issue wakeup events is a policy
decision, and it is managed by user space through a sysfs attribute: the
-power/wakeup file. User space can write the strings "enabled" or "disabled" to
-set or clear the "should_wakeup" flag, respectively. This file is only present

+to it to indicate whether or not, respectively, the device is supposed to signal
+system wakeup. This file is only present if the "power.wakeup" object exists
+for the given device and is created (or removed) along with that object, by
+device_set_wakeup_capable(). Reads from the file will return the corresponding
+string.
-The device_may_wakeup() routine returns true only if both flags are set.
+The "power/wakeup" file is supposed to contain the "disabled" string initially
+for the majority of devices; the major exceptions are power buttons, keyboards,
+and Ethernet adapters whose WoL (wake-on-LAN) feature has been set up with
+ethtool. It should also default to "enabled" for devices that don't generate

+another (like PCI Express ports).
+
+The device_may_wakeup() routine returns true only if the "power.wakeup" object
+exists and the corresponding "power/wakeup" file contains the string "enabled".
This information is used by subsystems, like the PCI bus type code, to see
whether or not to enable the devices' wakeup mechanisms. If device wakeup
mechanisms are enabled or disabled directly by drivers, they also should use
device_may_wakeup() to decide what to do during a system sleep transition.
-However for runtime power management, wakeup events should be enabled whenever
-the device and driver both support them, regardless of the should_wakeup flag.
+Device drivers, however, are not supposed to call device_set_wakeup_enable()
+directly in any case.
+It ought to be noted that system wakeup is conceptually different from "remote
+wakeup" used by runtime power management, although it may be supported by the
+same physical mechanism. Remote wakeup is a feature allowing devices in
+low-power states to trigger specific interrupts to signal conditions in which
+they should be put into the full-power state. Those interrupts may or may not
+be used to signal system wakeup events, depending on the hardware design. On
+some systems it is impossible to trigger them from system sleep states. In any
+case, remote wakeup should always be enabled for runtime power management for
+all devices and drivers that support it.

+ * The externally visible transitions are handled with the help of callbacks
+ * included in this structure in such a way that two levels of callbacks are
+ * involved. First, the PM core executes callbacks provided by PM domains,
+ * device types, classes and bus types. They are the subsystem-level callbacks
+ * supposed to execute callbacks provided by device drivers, although they may
+ * choose not to do that. If the driver callbacks are executed, they have to
+ * collaborate with the subsystem-level callbacks to achieve the goals
+ * appropriate for the given system transition, given transition phase and the
+ * subsystem the device belongs to.
*
- * @prepare: Prepare the device for the upcoming transition, but do NOT change
- * its hardware state. Prevent new children of the device from being
- * registered after @prepare() returns (the driver's subsystem and
- * generally the rest of the kernel is supposed to prevent new calls to the
- * probe method from being made too once @prepare() has succeeded). If
- * @prepare() detects a situation it cannot handle (e.g. registration of a
- * child already in progress), it may return -EAGAIN, so that the PM core
- * can execute it once again (e.g. after the new child has been registered)
- * to recover from the race condition. This method is executed for all
- * kinds of suspend transitions and is followed by one of the suspend
- * callbacks: @suspend(), @freeze(), or @poweroff().
- * The PM core executes @prepare() for all devices before starting to
- * execute suspend callbacks for any of them, so drivers may assume all of
- * the other devices to be present and functional while @prepare() is being
- * executed. In particular, it is safe to make GFP_KERNEL memory
- * allocations from within @prepare(). However, drivers may NOT assume
- * anything about the availability of the user space at that time and it
- * is not correct to request firmware from within @prepare() (it's too
- * late to do that). [To work around this limitation, drivers may
- * register suspend and hibernation notifiers that are executed before the
- * freezing of tasks.]
+ * @prepare: The principal role of this callback is to prevent new children of
+ * the device from being registered after it has returned (the driver's
+ * subsystem and generally the rest of the kernel is supposed to prevent
+ * new calls to the probe method from being made too once @prepare() has
+ * succeeded). If @prepare() detects a situation it cannot handle (e.g.
+ * registration of a child already in progress), it may return -EAGAIN, so

+ * been registered) to recover from the race condition.
+ * This method is executed for all kinds of suspend transitions and is
+ * followed by one of the suspend callbacks: @suspend(), @freeze(), or
+ * @poweroff(). The PM core executes subsystem-level @prepare() for all
+ * devices before starting to invoke suspend callbacks for any of them, so
+ * generally devices may be assumed to be functional or to respond to
+ * runtime resume requests while @prepare() is being executed. However,
+ * device drivers may NOT assume anything about the availability of user
+ * space at that time and it is NOT valid to request firmware from within
+ * @prepare() (it's too late to do that). It also is NOT valid to allocate
+ * substantial amounts of memory from @prepare() in the GFP_KERNEL mode.
+ * [To work around these limitations, drivers may register suspend and
+ * hibernation notifiers to be executed before the freezing of tasks.]
*
* @complete: Undo the changes made by @prepare(). This method is executed for
* all kinds of resume transitions, following one of the resume callbacks:
* @resume(), @thaw(), @restore(). Also called if the state transition
- * fails before the driver's suspend callback (@suspend(), @freeze(),
- * @poweroff()) can be executed (e.g. if the suspend callback fails for one

- * resume callback for all devices.
+ * The PM core executes subsystem-level @complete() after it has executed
+ * the appropriate resume callbacks for all devices.

* @suspend: Executed before putting the system into a sleep state in which the
- * contents of main memory are preserved. Quiesce the device, put it into
- * a low power state appropriate for the upcoming system state (such as
- * PCI_D3hot), and enable wakeup events as appropriate.

+ * Subsystem-level @suspend() is executed for all devices after invoking

*
* @resume: Executed after waking the system up from a sleep state in which the
- * contents of main memory were preserved. Put the device into the
- * appropriate state, according to the information saved in memory by the
- * preceding @suspend(). The driver starts working again, responding to
- * hardware events and software requests. The hardware may have gone
- * through a power-off reset, or it may have maintained state from the
- * previous suspend() which the driver may rely on while resuming. On most

+ * To keep things simple, lets assume adj == 1 for now.
+ *
+ * When adj != 1, remember that the interval and offset values
+ * have been appropriately scaled so the math is the same.
+ *
+ * The basic idea here is that we're increasing the multiplier
+ * by one, this causes the xtime_interval to be incremented by
+ * one cycle_interval. This is because:
+ * xtime_interval = cycle_interval * mult
+ * So if mult is being incremented by one:
+ * xtime_interval = cycle_interval * (mult + 1)
+ * Its the same as:
+ * xtime_interval = (cycle_interval * mult) + cycle_interval
+ * Which can be shortened to:
+ * xtime_interval += cycle_interval
+ *
+ * So offset stores the non-accumulated cycles. Thus the current
+ * time (in shifted nanoseconds) is:
+ * now = (offset * adj) + xtime_nsec
+ * Now, even though we're adjusting the clock frequency, we have
+ * to keep time consistent. In other words, we can't jump back
+ * in time, and we also want to avoid jumping forward in time.
+ *
+ * So given the same offset value, we need the time to be the same
+ * both before and after the freq adjustment.
+ * now = (offset * adj_1) + xtime_nsec_1
+ * now = (offset * adj_2) + xtime_nsec_2
+ * So:
+ * (offset * adj_1) + xtime_nsec_1 =
+ * (offset * adj_2) + xtime_nsec_2
+ * And we know:
+ * adj_2 = adj_1 + 1
+ * So:
+ * (offset * adj_1) + xtime_nsec_1 =
+ * (offset * (adj_1+1)) + xtime_nsec_2
+ * (offset * adj_1) + xtime_nsec_1 =
+ * (offset * adj_1) + offset + xtime_nsec_2
+ * Canceling the sides:
+ * xtime_nsec_1 = offset + xtime_nsec_2
+ * Which gives us:
+ * xtime_nsec_2 = xtime_nsec_1 - offset
+ * Which simplfies to:
+ * xtime_nsec -= offset
+ *
