NAME

6       __pci_enable_wake - enable PCI device as wakeup event source
7

SYNOPSIS

9       int __pci_enable_wake(struct pci_dev * dev, pci_power_t state,
10                             bool runtime, bool enable);
11

ARGUMENTS

13       dev
14           PCI device affected
15
16       state
17           PCI state from which device will issue wakeup events
18
19       runtime
20           True if the events are to be generated at run time
21
22       enable
23           True to enable event generation; false to disable
24

DESCRIPTION

26       This enables the device as a wakeup event source, or disables it. When
27       such events involves platform-specific hooks, those hooks are called
28       automatically by this routine.
29
30       Devices with legacy power management (no standard PCI PM capabilities)
31       always require such platform hooks.
32

RETURN VALUE

34       0 is returned on success -EINVAL is returned if device is not supposed
35       to wake up the system Error code depending on the platform is returned
36       if both the platform and the native mechanism fail to enable the
37       generation of wake-up events
