It is the flow diagram that a kind of set-top box provided in an embodiment of the present invention forces standby method with reference to Fig. 1, Fig. 1.
As shown in Figure 1, the set-top box forces the standby method to include:
Step 101, increase by first in framework layer and force standby interface, described first forces standby interface for connecting upper layer
Using and system；
Step 102, by described first force standby interface and default call method call the second of hardware layer force to
Machine interface；
Preferably, described to force standby interface and default call method to call the second of hardware layer to force by described first
Standby interface, comprising:
By the PowerManagerService of the framework layer, then it is transferred to by jni the power.c of the hardware layer
In second force standby interface.
Step 103, force standby interface that the first field and the second field are written in inner nuclear layer by described second, it is described
First field is used for screen closing operation, and second field is for forcing standby operation；
It is preferably, described to force standby interface that the first field and the second field are written in inner nuclear layer by described second,

Standby interface forcesuspend is forced in addition in PowerManager, which is supplied directly to upper layer application
It is called 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 hardware layers of power.c eventually by jni is connect
Mouthful.
The first write-in into "/sys/class/amhdmitx/amhdmitx0/config " of force_suspend interface
" video_off " field, i.e. progress screen closing operation；Then toward write-in " force_ inside "/sys/power/wake_unlock "
Suspend " field.
An interface force_suspend is realized in kernel, work queue is added in suspend function by interface the inside
And it is immediately performed.
Once "/sys/power/wake_unlock " has field write-in, wake_unlock_store function is most in kernel
It can be called back eventually, it before calling real wake_unlock here first can find whether the lock is deposited in red-black number chained list
If there is no then directly returning, do not continuing to operate.So we add a judgement herein, if coming into the field come
(field read out from "/sys/power/wake_unlock ") is " force_suspend ", then does not have to judgement lock and exist
Existence in red-black number chained list, calls directly the interface force_suspend of previous step realization, and entrance is very standby.
Certainly, due to the difference of standby mode, a global variable controls standby mode in kernel, it is strong due to us
Make it is standby belong to it is very standby, so, need to be set to true standby mode before calling suspend.
There is the mechanism of many places detection lock in kernel, even if no exception in suspend function, so to be also transformed
Suspend function: a global pressure standby mark is set in force_suspend function, is locked in suspend function check
Place is new plus a judgement once detecting pressure standby mark does not just detect lock, continue to execute down.
In addition, kernel can also be adjusted for the last time when every standby preparation is ready to enter system standby
The presence locked with power_suspend_late function check then wakes up system if there is lock.So herein also will be by upper
The pressure standby mark of one step addition adds a judgement newly to judge no needs detection lock.
Normal Standby success may be implemented in aforesaid way, and verifying includes normal condition and abnormal conditions, and normal condition includes
It forces to force standby, plug peripheral hardware when standby including each interface operation when playing various videos.Abnormal conditions include by answering
Force standby, standby by force using circulation acquisition lock with lock is not discharged after acquisition lock.
