Re: sleep-wakeup & kexts

Ah yes, to PMInit or not to PMInit. Actually the call to PMInit is
suppose to be made by Policy Maker not Power Controller as stated by
Chapter 10 of IOKit Fundamentals. I believe you are a power controller.

Per page 135:
If an IOService
object is not a policy maker (that is, it does not call PMinit) its
power-management
instance variables are not initialized with the appropriate objects.

I am in the process of adding this code to my driver to see if an entry
is made to the IORegistry IOPower plane. I presently see my driver in
the IOPower plane without making the call. I have more work to do to
completely understand what is or is not happening.

Manooch if you are working on a driver then you may have the enclosure
door open. I used to do that myself, but you cannot sleep a 10 machine
with the enclosure open. My point is twofold.

Check the IOPower plane looking for your driver and shut the door.
You're letting the cold in as my mother use to say.

As soon as I finish this driver it will be added to the PM DDK.

I regret the delay. Wayne
