It seems it should be enough to implement runtime PM in the PCI controller. Isn't each PCI WAKE# line is wired from each PCI device to the PCI controller? Then the PCI controller can figure out from which PCI device the WAKE# came from. > Options I can think of: > (1) implement runtime PM callbacks for all PCI devices, where we clear > any PME status and ensure WAKE# stops asserting [1] I don't think this is needed, it should be enough to have just the PCI controller implement runtime PM :) Regards, Tony
