2010-05-10PM: pm_wakeup - switch to using boolDmitry Torokhov
Also change couple of stubs implemented as macros in !CONFIG_PM case in statinc inline functions to provide proper typechecking of arguments regardless of config. Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2008-07-14PCI: include linux/pm_wakeup.h for device_set_wakeup_capableStephen Rothwell
drivers/pci/pci.c needs pm_wakeup.h since it uses device_set_wakup_capable(). The latter also needs to be stubbed out for !CONFIG_PM. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2008-07-07PCI ACPI: Rework PCI handling of wake-upRafael J. Wysocki
* Introduce function acpi_pm_device_sleep_wake() for enabling and disabling the system wake-up capability of devices that are power manageable by ACPI. * Introduce function acpi_bus_can_wakeup() allowing other (dependent) subsystems to check if ACPI is able to enable the system wake-up capability of given device. * Introduce callback .sleep_wake() in struct pci_platform_pm_ops and for the ACPI PCI 'driver' make it use acpi_pm_device_sleep_wake(). * Introduce callback .can_wakeup() in struct pci_platform_pm_ops and for the ACPI 'driver' make it use acpi_bus_can_wakeup(). * Move the PME# handlig code out of pci_enable_wake() and split it into two functions, pci_pme_capable() and pci_pme_active(), allowing the caller to check if given device is capable of generating PME# from given power state and to enable/disable the device's PME# functionality, respectively. * Modify pci_enable_wake() to use the new ACPI callbacks and the new PME#-related functions. * Drop the generic .platform_enable_wakeup() callback that is not used any more. * Introduce device_set_wakeup_capable() that will set the power.can_wakeup flag of given device. * Rework PCI device PM initialization so that, if given device is capable of generating wake-up events, either natively through the PME# mechanism, or with the help of the platform, its power.can_wakeup flag is set and its power.should_wakeup flag is unset as appropriate. * Make ACPI set the power.can_wakeup flag for devices found to be wake-up capable by it. * Make the ACPI wake-up code enable/disable GPEs for devices that have the wakeup.flags.prepared flag set (which means that their wake-up power has been enabled).

2008-04-19PM: Convert wakeup flag accessors to inline functionsAlan Stern
This patch (as1058) improves the wakeup macros in include/linux/pm.h. All but the trivial ones are converted to inline routines, which requires moving them to a separate header file since they depend on the definition of struct device.
