From 0ac85241ebc7bf6b86ab498960cc121d53ef69ae Mon Sep 17 00:00:00 2001 From: David Brownell Date: Mon, 12 Sep 2005 19:39:34 -0700 Subject: [PATCH] driver model wakeup flags This is a refresh of an earlier patch to add "wakeup" support to the PM core model. This provides per-device bus-neutral control of the use of wakeup events. * "struct device_pm_info" has two bits that are initialized as part of setting up the enclosing struct device: - "can_wakeup", reflecting hardware capabilities - "may_wakeup", the policy setting (when CONFIG_PM) * There's a writeable sysfs "wakeup" file, with one of two values: - "enabled", when the policy is to allow wakeup - "disabled", when the policy is not to allow it - "" if the device can't currently issue wakeups By default, wakeup is enabled on all devices that support it. If its driver doesn't support it ... treat it as a bug. :) Signed-off-by: David Brownell Signed-off-by: Greg Kroah-Hartman --- drivers/base/core.c | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/base/core.c') diff --git a/drivers/base/core.c b/drivers/base/core.c index 6ab73f5c799a..31109193e2c4 100644 --- a/drivers/base/core.c +++ b/drivers/base/core.c @@ -225,6 +225,7 @@ void device_initialize(struct device *dev) klist_children_put); INIT_LIST_HEAD(&dev->dma_pools); init_MUTEX(&dev->sem); + device_init_wakeup(dev, 0); } /** -- cgit v1.2.3
