Well, these are nice features, but what kind of machine does you test? Does it have several level hierarchy? The most powerful system I saw just has two levels, which sounds not worth adding partial aspm. The second feature seems more reasonable. ASPM is still broken in a lot of devices, before we go far, we need to make sure the feature is really required.
