The _OST contains two arguments: The first is the PERFORMANCE notificatin event. The second is the status of _PPC object. OSPM will convey the _PPC evaluation status to the platform. Of course when the module parameter of "ignore_ppc" is added, OSPM won't evaluate the _PPC object. But it will call the _OST object. At the same time the _OST object will be evaluated only when the PERFORMANCE notification event is received. Signed-off-by: Zhao Yakui Signed-off-by: Len Brown --- Reading git-diff-tree failed
