"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

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

devices to support suspend/resume, many of them do not.
In fact so many don't that by default, the USB core

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.

More interestingly, a device might undergo a manual resume or
autoresume during system suspend. With current kernels this shouldn't
happen, because manual resumes must be initiated by userspace and
autoresumes happen in response to I/O requests, but all user processes
and I/O should be quiescent during a system suspend -- thanks to the
freezer. However there are plans to do away with the freezer, which
would mean these things would become possible. If and when this comes
about, the USB core will carefully arrange matters so that either type
of resume will block until the entire system has resumed.

/* 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.
