if an interrupt causes the system to resume normal processing, the

interrupt may or may not have been handled when the BIOS returns

from this call; thus, the caller should allow interrupts on return

interrupt handlers may not retain control if the BIOS allows

interrupts while in idle mode even if they are able to determine

that they were called from idle mode

the caller should issue this call continuously in a loop until it needs

Notes: although power management events are often asynchronous, notification
|
||
|
|
will not be made until polled via this call to permit software to
|
||
|
|
only receive event notification when it is prepared to process
|
||
|
|
power management events; since these events are not very time-
|
||
|
|
critical, it should be sufficient to poll once or twice per second
|
||
|
|
the critical resume notification is made after the system resumes
|
||
|
|
from an emergency suspension; normally, the system BIOS only notifies
|
||
|
|
its partner that it wishes to suspend and relies on the partner to
|
||
|
|
actually request the suspension, but no notification is made on an
|
||
|
|
emergency suspension
|
||
|
|
should not be called from within a hardware interrupt handler to avoid
|
||
|
|
reentrance problems
