Please, really, don't do that. Pushing power policy decisions into multiple bits of the stack makes things much more awkward, especially when the criteria you're describing are about the least interesting reasons for switching these states. They're most relevant on multi-socket systems, and the overwhelming power concern there is rack-level overcommit or cooling. You're going to need an external policy agent to handle the majority of cases people actually care about. -- Matthew Garrett | mj...@srcf.ucam.org -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
