717 @param aPtr The iPtr stored in the SCpuIdleHandler structure |
718 @param aStage Bits 0-7 give a bitmask of CPUs now active, i.e. 0 means all processors now idle |
718 @param aStage If positive, the number of processors still active |
719 Bit 31 set indicates that the current core can now be powered down |
719 If zero, indicates all processors are now idle |
720 Bit 30 set indicates that other cores still remain to be retired |
720 -1 indicates that postamble processing is required after waking up |
