AFAIK, we've never seen a machine that depends on an "implicit notify" on a device when a wake GPE happens. Such behaviour would be irrelevant for system sleep/wake - the only requirement is in runtime power management. > It appears to me that the biggest issue right now is the fact that a Notify() must be performed on a Device object, and the problem is how to associate the GPE with the device object. The other important aspect of this is that a single GPE may correspond to multiple devices. The methods will generally cope with this by either sending multiple notifies, executing some SMM code to identify the relevant device or reading PCI configuration registers to identify the source of the wakeup. We need to handle that case as well. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- 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
