Simple Power Question

Hey all -

Simple power management question.

Does the power manager save your device Extension structure on a power down
cycle. Is it safe to assume that anything in your device extension will be
there when you power up, but if there is any data you have been managing
outside of the device extension, it is up to you to save it.

I am new to Power Manangemt, and have gotten it working in my code, but am
now at the “Now that It is working, why is it working !” phase.

Thanks !

-Chris

Yes it saves all the data related to the driver and everythign in the memory, only that the driver has to take care of the hardware.
The driver must save the hardware status somewhere in the memory/disk and then take appropriate actions to ensure that the hardware
is functional after/before a PM event.
