pci_enable_wake(9)
NAME
pci_enable_wake - enable PCI device as wakeup event source
SYNOPSIS
int pci_enable_wake(struct pci_dev * dev, pci_power_t state,
int enable);
ARGUMENTS
- dev
- PCI device affected
- state
- PCI state from which device will issue wakeup events
- enable
- True to enable event generation; false to disable
DESCRIPTION
This enables the device as a wakeup event source, or disables it. When
such events involves platform-specific hooks, those hooks are called
automatically by this routine.
Devices with legacy power management (no standard PCI PM capabilities)
always require such platform hooks. Depending on the platform, devices
supporting the standard PCI PME# signal may require such platform
hooks; they always update bits in config space to allow PME#
generation.
-EIO is returned if the device canīt ever be a wakeup event source.
-EINVAL is returned if the device canīt generate wakeup events from the
specified PCI state. Returns zero if the operation is successful.
