Concrete, as in figure 2 it is shown, a kind of Set Top Box that Fig. 2 is the embodiment of the present invention to be provided forces standby method signal
Figure.
Adding in PowerManager and force standby interface forcesuspend, this interface is supplied directly to upper layer application
Call with system.
As the call flow of other interfaces such as reboot, the realization of forcesuspend also exists
In PowerManagerService, the force_suspend being transferred in the power.c of hardware layer eventually through jni connects
Mouthful.
Force_suspend interface is first toward write in "/sys/class/amhdmitx/amhdmitx0/config "
" video_off " field, i.e. carries out closing screen operation；Then toward "/sys/power/wake_unlock " the inside write " force_
Suspend " field.
In kernel, realize an interface force_suspend, inside this interface, suspend function is added work queue
And be immediately performed.
Once "/sys/power/wake_unlock " has field to write, and in kernel, wake_unlock_store function is
Can be called back eventually, before calling real wake_unlock, understand it here first can find whether this lock is deposited in red-black number chained list
, if there is no the most directly returning, do not continue operation.So, we here add a judgement, if the field come into
(field i.e. read out from "/sys/power/wake_unlock ") is " force_suspend ", then need not judge to be locked in
Existence in red-black number chained list, directly invokes the interface force_suspend that previous step realizes, enters the most standby.
Certainly, due to the difference of standby mode, kernel has individual global variable to control standby mode, strong due to us
Make and standby belong to the most standby, so, need to be set to true standby mode before calling suspend.
Kernel has the mechanism of many places detection lock, though no exception in suspend function, so also to transform
Suspend function a: overall situation is set in force_suspend function and forces standby mark, lock at suspend function check
Place newly add a judgement, pressure standby mark once detected, the most do not detect lock, continue down to perform.
It addition, every standby preparation is ready will enter system standby when, kernel also can be adjusted for the last time
With the existence of power_suspend_late function check lock, if there being lock, then wake up system up.So the most also will be by upper
The newly added judgement of pressure standby mark that one step is added judges that no needs detects lock.
Aforesaid way can realize normal Standby success, and checking includes normal condition and abnormal conditions, and normal condition includes
Force when playing various video standby, include forcing during each interface operation standby, plug peripheral hardware.Abnormal conditions include by answering
Carry out forcing with not discharging lock after obtaining lock standby, obtained by application circulation and lock and carry out forcing standby.
