Rafael J. Wysocki 0baed8da1e PCI / ACPI PM: Propagate wake-up enable for devices w/o ACPI support ... Some PCI devices (not PCI Express), like PCI add-on cards, can generate PME#, but they don't have any special platform wake-up support. For this reason, even if they generate PME# to wake up the system from a sleep state, wake-up events are not generated by the platform. It turns out that, at least on some systems, PCI bridges and the PCI host bridge have ACPI GPEs associated with them that, if enabled to generate wake-up events, allow the system to wake up if one of the add-on devices asserts PME# while the system is in a sleep state. Following this observation, if a PCI device without direct ACPI wake-up support is prepared to wake up the system during a transition into a sleep state (eg. suspend to RAM), try to configure the bridges on the path from the device to the root bridge to wake-up the system.
