Question about CPU Power Management  
Hi, 
I've been reading some documentation about CPU PM, and have some question you guys might be able to answer  :


1. PM Decides to put CPU in low-power sleep, at this point - PM does not know when is the next scheduled timer event. 
Lets say next timer event is in 100us, and it takes 150us for the HW enter lop-power mode. 
CPU goes to low-power sleep, and wakeup right away due to timer wakeup. BUT -  Timer interrupt is served in 50us delay. 
is this something that being\should be handled? 


2. Assume power() callout is called and put the CPU into a low-power sleep. now there is a wakeup event,where is 
execution resumes from ? callout ? 

Thanks, 
Ran
