So the xen hypervizor is responsible for power management decisions, but it doesn't know how to talk to the power management controls in the platform? Why is that a good idea? Does somebody expect all this dom0 stuff to really live in the upstream linux kernel source tree? I'd like the patch better if you s/extcntl/xen/ to make it clear why this code exists -- or is there an expected "external control" other than Xen? -Len -- 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
