successful, will make the kernel abort a subsequent transition
to a sleep state if any wakeup events are reported after the
write has returned.
What: /sys/power/reserved_size
Date: May 2011
Contact: Rafael J. Wysocki <rjw@sisk.pl>
Description:
The /sys/power/reserved_size file allows user space to control
the amount of memory reserved for allocations made by device
drivers during the "device freeze" stage of hibernation. It can
be written a string representing a non-negative integer that
will be used as the amount of memory to reserve for allocations
made by device drivers' "freeze" callbacks, in bytes.
Reading from this file will display the current value, which is
set to 1 MB by default.

time.) Unlike the other suspend-related phases, during the prepare
phase the device tree is traversed top-down.
The prepare phase uses only a bus callback. After the callback method
returns, no new children may be registered below the device. The method
may also prepare the device or driver in some way for the upcoming
system power transition, but it should not put the device into a
low-power state.
In addition to that, if device drivers need to allocate additional
memory to be able to hadle device suspend correctly, that should be
done in the prepare phase.
After the prepare callback method returns, no new children may be
registered below the device. The method may also prepare the device or
driver in some way for the upcoming system power transition (for
example, by allocating additional memory required for this purpose), but
it should not put the device into a low-power state.

I/O. They also may save the device registers and put it into the

Suspend notifiers
(C) 2007 Rafael J. Wysocki <rjw@sisk.pl>, GPL
(C) 2007-2011 Rafael J. Wysocki <rjw@sisk.pl>, GPL
There are some operations that device drivers may want to carry out in their
.suspend() routines, but shouldn't, because they can cause the hibernation or
suspend to fail. For example, a driver may want to allocate a substantial amount
of memory (like 50 MB) in .suspend(), but that shouldn't be done after the
swsusp's memory shrinker has run.
There are some operations that subsystems or drivers may want to carry out
before hibernation/suspend or after restore/resume, but they require the system
to be fully functional, so the drivers' and subsystems' .suspend() and .resume()
or even .prepare() and .complete() callbacks are not suitable for this purpose.
For example, device drivers may want to upload firmware to their devices after
resume/restore, but they cannot do it by calling request_firmware() from their
.resume() or .complete() routines (user land processes are frozen at these
points). The solution may be to load the firmware into memory before processes
are frozen and upload it from there in the .resume() routine.
A suspend/hibernation notifier may be used for this purpose.
Also, there may be some operations, that subsystems want to carry out before a
hibernation/suspend or after a restore/resume, requiring the system to be fully
functional, so the drivers' .suspend() and .resume() routines are not suitable
for this purpose. For example, device drivers may want to upload firmware to
their devices after a restore from a hibernation image, but they cannot do it by
calling request_firmware() from their .resume() routines (user land processes
are frozen at this point). The solution may be to load the firmware into
memory before processes are frozen and upload it from there in the .resume()
routine. Of course, a hibernation notifier may be used for this purpose.
The subsystems that have such needs can register suspend notifiers that will be
called upon the following events by the suspend core:
