Description:
Each USB device directory will contain a file named
power/level. This file holds a power-level setting for
- the device, one of "on", "auto", or "suspend".
+ the device, either "on" or "auto".
"on" means that the device is not allowed to autosuspend,
although normal suspends for system sleep will still
be honored. "auto" means the device will autosuspend
and autoresume in the usual manner, according to the
- capabilities of its driver. "suspend" means the device
- is forced into a suspended state and it will not autoresume
- in response to I/O requests. However remote-wakeup requests
- from the device may still be enabled (the remote-wakeup
- setting is controlled separately by the power/wakeup
- attribute).

During normal use, devices should be left in the "auto"

+ level. The "on" level is meant for administrative uses.
If you want to suspend a device immediately but leave it
free to wake up in response to I/O requests, you should
write "0" to power/autosuspend.
+ Device not capable of proper suspend and resume should be
+ left in the "on" level. Although the USB spec requires
+ devices to support suspend/resume, many of them do not.
+ In fact so many don't that by default, the USB core

+
+In particular, if the driver requires remote wake-up capability (i.e. hardware
+mechanism allowing the device to request a change of its power state, such as
+PCI PME) for proper functioning and device_run_wake() returns 'false' for the
+device, then ->runtime_suspend() should return -EBUSY. On the other hand, if
+device_run_wake() returns 'true' for the device and the device is put into a low
+power state during the execution of the subsystem-level suspend callback, it is
+expected that remote wake-up will be enabled for the device. Generally, remote
+wake-up should be enabled for all input devices put into a low power state at
+run time.
+
+The subsystem-level resume callback is _entirely_ _responsible_ for handling the
+resume of the device as appropriate, which may, but need not include executing
+the device driver's own ->runtime_resume() callback (from the PM core's point of
+view it is not necessary to implement a ->runtime_resume() callback in a device
+driver as long as the subsystem-level resume callback knows what to do to handle
+the device).
+
+ * Once the subsystem-level resume callback has completed successfully, the PM
+ core regards the device as fully operational, which means that the device
+ _must_ be able to complete I/O operations as needed. The run-time PM status

+
+The subsystem-level idle callback is executed by the PM core whenever the device

+6. Run-time PM and System Sleep
+
+Run-time PM and system sleep (i.e., system suspend and hibernation, also known
+as suspend-to-RAM and suspend-to-disk) interact with each other in a couple of
+ways. If a device is active when a system sleep starts, everything is
+straightforward. But what should happen if the device is already suspended?
+
+The device may have different wake-up settings for run-time PM and system sleep.
+For example, remote wake-up may be enabled for run-time suspend but disallowed
+for system sleep (device_may_wakeup(dev) returns 'false'). When this happens,
+the subsystem-level system suspend callback is responsible for changing the
+device's wake-up setting (it may leave that to the device driver's system
+suspend routine). It may be necessary to resume the device and suspend it again
+in order to do so. The same is true if the driver uses different power levels
+or other settings for run-time suspend and system sleep.
+
+During system resume, devices generally should be brought back to full power,
+even if they were suspended before the system sleep began. There are several
+reasons for this, including:
+
+ * The device might need to switch power levels, wake-up settings, etc.
+
+ * Remote wake-up events might have been lost by the firmware.
+
+ * The device's children may need the device to be at full power in order
+ to resume themselves.
+
+ * The driver's idea of the device state may not agree with the device's
+ physical state. This can happen during resume from hibernation.
+
+ * The device might need to be reset.
+
+ * Even though the device was suspended, if its usage counter was > 0 then most
+ likely it would need a run-time resume in the near future anyway.
+
+ * Always going back to full power is simplest.
+
+If the device was suspended before the sleep began, then its run-time PM status
+will have to be updated to reflect the actual post-system sleep status. The way
+to do this is:
+
+ pm_runtime_disable(dev);
+ pm_runtime_set_active(dev);
+ pm_runtime_enable(dev);
+
+The PM core always increments the run-time usage counter before calling the
+->prepare() callback and decrements it after calling the ->complete() callback.
+Hence disabling run-time PM temporarily like this will not cause any run-time
+suspend callbacks to be lost.

+* OpenPIC and its interrupt numbers on Freescale's e500/e600 cores
+
+The OpenPIC specification does not specify which interrupt source has to
+become which interrupt number. This is up to the software implementation
+of the interrupt controller. The only requirement is that every
+interrupt source has to have an unique interrupt number / vector number.
+To accomplish this the current implementation assigns the number zero to
+the first source, the number one to the second source and so on until
+all interrupt sources have their unique number.
+Usually the assigned vector number equals the interrupt number mentioned
+in the documentation for a given core / CPU. This is however not true
+for the e500 cores (MPC85XX CPUs) where the documentation distinguishes
+between internal and external interrupt sources and starts counting at
+zero for both of them.
+
+So what to write for external interrupt source X or internal interrupt
+source Y into the device tree? Here is an example:
+
+The memory map for the interrupt controller in the MPC8544[0] shows,
+that the first interrupt source starts at 0x5_0000 (PIC Register Address
+Map-Interrupt Source Configuration Registers). This source becomes the
+number zero therefore:
+ External interrupt 0 = interrupt number 0
+ External interrupt 1 = interrupt number 1
+ External interrupt 2 = interrupt number 2
+ ...
+Every interrupt number allocates 0x20 bytes register space. So to get
+its number it is sufficient to shift the lower 16bits to right by five.
+So for the external interrupt 10 we have:
+ 0x0140 >> 5 = 10
+
+After the external sources, the internal sources follow. The in core I2C
+controller on the MPC8544 for instance has the internal source number
+27. Oo obtain its interrupt number we take the lower 16bits of its memory
+address (0x5_0560) and shift it right:
+ 0x0560 >> 5 = 43
+
+Therefore the I2C device node for the MPC8544 CPU has to have the
+interrupt number 43 specified in the device tree.

+/* NVIDIA context programs handle a number of other conditions which are
+ * not implemented in our versions. It's not clear why NVIDIA context
+ * programs have this code, nor whether it's strictly necessary for
+ * correct operation. We'll implement additional handling if/when we
+ * discover it's necessary.
+ *
+ * - On context save, NVIDIA set 0x400314 bit 0 to 1 if the "3D state"
+ * flag is set, this gets saved into the context.
+ * - On context save, the context program for all cards load nsource
+ * into a flag register and check for ILLEGAL_MTHD. If it's set,
+ * opcode 0x60000d is called before resuming normal operation.
+ * - Some context programs check more conditions than the above. NV44
+ * checks: ((nsource & 0x0857) || (0x400718 & 0x0100) || (intr & 0x0001))
+ * and calls 0x60000d before resuming normal operation.
+ * - At the very beginning of NVIDIA's context programs, flag 9 is checked
+ * and if true 0x800001 is called with count=0, pos=0, the flag is cleared
+ * and then the ctxprog is aborted. It looks like a complicated NOP,
+ * its purpose is unknown.
+ * - In the section of code that loads the per-vs state, NVIDIA check
+ * flag 10. If it's set, they only transfer the small 0x300 byte block
+ * of state + the state for a single vs as opposed to the state for
+ * all vs units. It doesn't seem likely that it'll occur in normal
+ * operation, especially seeing as it appears NVIDIA may have screwed
+ * up the ctxprogs for some cards and have an invalid instruction
+ * rather than a cp_lsr(ctx, dwords_for_1_vs_unit) instruction.
+ * - There's a number of places where context offset 0 (where we place
+ * the PRAMIN offset of the context) is loaded into either 0x408000,
+ * 0x408004 or 0x408008. Not sure what's up there either.
+ * - The ctxprogs for some cards save 0x400a00 again during the cleanup
+ * path for auto-loadctx.
