The current cpu offline essentially just runs a special idle loop. The standard idle loop is even a bit more aggressive on some systems because it knows about the deeper ACPI sleep modi. There are also dependencies between cores because current CPUs have shared power planes between cores. I suppose in the future when a whole socket goes off line one could implement special code to turn off the CPU further. But it likely won't work on older hardware. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
