It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Fig. 1 is a schematic diagram of an internal structure of a computer device according to an embodiment. As shown in fig. 1, the computer device includes a processor, a memory, and a network interface connected by a system bus. Wherein, the processor is used for providing calculation and control capability and supporting the operation of the whole computer equipment. The memory is used for storing data, programs and the like, and at least one computer program is stored on the memory, and can be executed by the processor to realize the information processing method suitable for the computer device provided in the embodiment of the application. The memory may include a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program. The computer program can be executed by a processor to implement an information processing method provided in each of the following embodiments. The internal memory provides a cached execution environment for the operating system computer programs in the non-volatile storage medium. The network interface may be an ethernet card or a wireless network card, etc. for communicating with an external computer device. The computer device may be a mobile phone, a tablet computer or a personal digital assistant or a wearable device, etc.

Those skilled in the art will appreciate that the architecture shown in fig. 1 is merely a block diagram of some of the structures associated with the disclosed aspects and is not intended to limit the computing devices to which the disclosed aspects apply, as particular computing devices may include more or less components than those shown, or may combine certain components, or have a different arrangement of components. For example, the computer device further includes a network interface connected via the system bus, where the network interface may be an ethernet card or a wireless network card, and the like, and is used for communicating with an external computer device, such as a server.

FIG. 2 is a diagram illustrating a portion of the architecture of a computer device, in accordance with one embodiment. As shown in FIG. 2, the architectural system of the computer device includes a Java space layer 210, a local framework layer 220, and a Kernel space layer 230. The Java space layer includes a freezing and unfreezing module 212, and the freezing and unfreezing module 212 is used for implementing a freezing policy for each application program, for example, freezing the application program consuming power in the background.

The local framework layer 220 includes a resource priority and restriction management module 222 and a platform freeze management module 224. The resource priority and restriction management module 222 may perform different resource restrictions on different applications, so that different applications are in different resource priorities. The resource priority and restriction management module 222 may also adjust the resource priority of the application according to the requirements of the upper layers so that the computer device can make it reasonable for the application to use the resources. The platform freezing management module 224 may determine the level of resource limitation on the process application program according to the time length of the application program entering the background, the platform freezing management module 224 may preset different levels of resource limitation, and the longer the time length of the application program entering the background is, the higher the level of resource limitation on the application program by the platform freezing management module 224 is, that is, the higher the degree of resource limitation on the application program is. Optionally, the resource restriction level may include: a CPU restricted sleep mode, a CPU frozen sleep mode, and a process deep frozen mode. The CPU restricted sleep mode is to restrict a Central Processing Unit (CPU) resource that can be used by a process of an application, so that the process of the application can use less CPU resource; network resources and input/output (I/O) resources that can be used by processes of the application may be further limited in the CPU limited sleep mode. The CPU freeze sleep mode is a deep restricted mode in which resources available to an application are not recovered, but CPU resources, network resources, and I/O resources are prohibited from being used by the process of the application. The process deep freezing mode is to prohibit the process of the application program from using CPU resources, network resources and I/O resources, and recycle the memory resources occupied by the process of the application program. The interface module of the local framework layer 220 includes a binder interface that is developed to the upper layer, and the framework or the application program of the upper layer can send a resource restriction instruction to the resource restriction management module 222 and send a freeze instruction to the platform freeze management module 224 through the binder interface.

The kernel space layer 230 includes a UID management module 231, a Cgroup module 232, a binder management and control module 233, a process memory recycling module 234, and a timeout freeze exit module 235. Currently, Process management for an application is implemented based on a Process Identification (PID), and a Process does not correspond to an application, which is not beneficial to uniformly managing resources corresponding to all processes of an application. The UID management module 231 may manage resources of the application program through a User Identifier (UID) of the application program, and may also freeze the application program through the UID of the application program. The Cgroup module 232 may provide a CPU, CPUSET, memory, I/O resources and Net related resource restriction mechanism. binder management module 233 may be used to limit the priority of background inter-process binder communications. The process memory recycling module 234 is configured to implement a process deep freeze mode, and release a file area of a process when the process enters the process deep freeze mode, thereby saving memory and speeding up the next start of an application program corresponding to the process. The timeout freeze exit module 235 is used to solve the problem that the process is abnormal during the freeze timeout.

Through the above-mentioned architecture, the information processing method in each embodiment of the present application can be realized.

FIG. 3 is a flow diagram of a method for information processing in one embodiment. As shown in fig. 3, an information processing method includes:

step 302, if a resource restriction instruction is received, a current electric quantity value and a current available memory value of the computer device are obtained.

When the computer device receives the resource restriction instruction, a current charge value and a current available memory value of the computer device may be obtained. The resource restriction instruction refers to a resource restriction instruction for the background application program, and the computer device may perform resource restriction on system resources occupied by the background application program, where the system resources may include: network resources, I/O resources, memory resources, and CPU resources. After the computer device obtains the current electricity value, the current electricity value may be represented as a percentage of the total amount of the battery or may be directly represented by electricity (e.g., 3500 milliamps). The current available memory value is the difference between the total memory value and the memory value occupied by the currently running application program.

And 304, acquiring a resource limitation strategy for limiting the resources of the background application program according to the current electric quantity value and the current available memory value.

After the computer device obtains the current electric quantity value and the current available memory value, a resource limitation strategy for limiting resources of the background application program can be obtained according to the current available electric quantity value and the current available memory value. The resource restriction policy includes a resource restriction list for performing resource restriction on the background application program and a resource restriction mode for performing resource restriction on the background application program. The resource restriction list includes an application program identifier of an application program requiring resource restriction, and the resource restriction mode includes a resource restriction level for resource restriction of the application program and a resource type for resource restriction of the application program.

And step 306, performing resource limitation on the background application program according to the resource limitation strategy.

After obtaining the resource restriction list and the resource restriction mode included in the resource restriction policy, the computer device may search for a corresponding background application program according to the application program identifier in the resource restriction list, and then perform resource restriction on the background application program. When the computer device performs resource limitation on the background application program, the computer device can search the resource limitation level corresponding to the background application program and the resource limitation category corresponding to the background application program. And performing resource limitation of corresponding types on the background application program according to the resource limitation types, and performing resource limitation of corresponding levels on the background application program according to the resource limitation levels. Optionally, the resource category for resource restriction of the background application by the computer device includes: CPU resources, I/O resources, memory resources, and network resources. The resource restriction level of the computer device for resource restriction on the background application program comprises the following steps: a CPU restricted sleep mode, a CPU frozen sleep mode, and a process deep frozen mode. The CPU limitation sleep mode is to limit CPU resources which can be used by the process of the application program, so that the process of the application program can use less CPU resources, and other system resources which can be used by the process of the application program are not limited; the CPU-restricted sleep mode may further restrict network resources and I/O resources that may be used by the process of the application in addition to restricting additional CPU resources that may be used by the process of the application. The CPU freeze sleep mode is a deep restricted mode in which resources available to an application are not recovered, but CPU resources, network resources, and I/O resources are prohibited from being used by the process of the application. The process deep freezing mode is to prohibit the process of the application program from using CPU resources, network resources and I/O resources, and recycle the memory resources occupied by the process of the application program.

According to the method, the computer equipment can limit the resources of the background application program according to the resource limit strategy after acquiring the resource limit strategy according to the current electric quantity value and the current available memory value, so that the intellectualization of resource limit on the background application program is improved, and the cruising ability of the computer equipment is enhanced.

In one embodiment, the resource restriction policy includes a resource restriction list and a resource restriction level. The step 304 of obtaining a resource restriction policy for performing resource restriction on the background application according to the current power value and the current available memory value includes:

(1) and acquiring the power consumption of the background application program, and determining the resource restriction list according to the current power value and the power consumption of the background application program.

(2) And determining the resource limitation level for limiting the resources of the background application programs in the resource limitation list according to the current available memory value.

The resource limitation policy comprises a resource limitation list and a resource limitation mode, the resource limitation list needs to carry out a list of background application programs subjected to resource limitation, and the resource limitation list comprises application program identifications of the background application programs subjected to resource limitation. The resource type and the resource limit level for resource limit of the background application program are performed in the resource limit mode.

The computer devices may obtain power consumption of the background applications, respectively. Alternatively, the power consumption of the background application may be the power consumption of the background application in a unit time, or may be the average power consumption of the background application. The computer device is pre-stored with the corresponding relation between the current electric quantity value and the electric consumption of the background application program requiring resource limitation. The computer equipment can search the corresponding background application program with the power consumption according to the current power value and then limit the resource of the corresponding background application program with the power consumption. Optionally, the computer device may divide the current charge value into 5 levels, including: 0 to 19 percent, 20 to 39 percent, 40 to 59 percent, 60 to 79 percent and 80 to 100 percent. The computer device can divide the application programs into 5 grades by the background application programs according to the sequence of the power consumption from high to low, wherein the power consumption of the application programs from 1 grade to 5 grade is gradually reduced. When the current electric quantity value of the computer equipment is 0-19%, resource limitation is carried out on the application programs with the electric consumption from the 1 st level to the 5 th level; when the current electric quantity value of the computer equipment is 20% -39%, resource limitation is carried out on the application programs with the electric consumption from the level 2 to the level 5; when the current electric quantity value of the computer equipment is 40% -59%, resource limitation is carried out on the application programs with the electric consumption from the 3 rd level to the 5 th level; when the current electric quantity value of the computer equipment is 60% -79%, resource limitation is carried out on the application programs with the electric consumption from the 4 th level to the 5 th level; when the current electric quantity value of the computer equipment is 80% -100%, resource limitation is carried out on the application program with the electric consumption at the 5 th level.

The computer device may also determine a resource restriction level for resource restricting the background application based on the current available memory value. The current available memory value is in a negative correlation with the resource restriction level, and when the current available memory value is lower, the resource restriction level of the background application program is higher; when the current available memory value is higher, the resource restriction level for the background application is lower. The higher the level of resource restriction on the background application, the less system resources are available to the background application. Optionally, the resource restriction level for the background application is from low to high, which is respectively the CPU restricted sleep mode, the CPU frozen sleep mode, and the process deep frozen mode.

According to the method, the background application program needing to be frozen can be determined according to the current electric quantity and the electric power consumption of the background application program, the resource limitation level for limiting the resources of the background application program can be determined according to the current available memory value, and the resource limitation mode of the background application program is more intelligent.

In one embodiment, the method further comprises: and acquiring the time length of the background application program entering the background, and adjusting the resource limitation level for limiting the resource of the background application program according to the time length.

The computer equipment can also acquire the time length of the background application program entering the background, and adjust the resource limitation level for limiting the resource of the background application program according to the time length of the background application program entering the background. Optionally, as the duration of the background application program entering the background increases, the resource restriction level of the computer device to the background application program also increases, that is, the longer the duration of the background application program entering the background is, the higher the resource restriction level of the computer device to the background application program is. The corresponding relation between the time length of entering the background and the resource limit level can be preset in the computer equipment, for example, the time length of entering the background reaches 1 hour, the resource limit level of the background application program is increased by 1 level, the time length of entering the background reaches 3 hours, and the resource limit level of the background application program is increased by 1 level.

After the computer equipment receives the resource limiting instruction to limit the resources of the background application program, the resource limiting level for limiting the resources of the background application program can be adjusted according to the time length for the background application program to enter the background, so that the resource limitation of the background application program by the computer equipment is more intelligent.

In one embodiment, the resource restriction instruction is received when at least one of the following conditions is met:

(1) the computer device is in a standby state. When the computer equipment is in a standby state, the kernel space in the computer equipment can send a resource limiting instruction to the user space, so that the user space can release system resources occupied by the background application program according to the resource limiting instruction. When the computer device receives the screen-off broadcast, the computer device can be judged to be in a standby state.

(2) The memory value occupied by the currently running application program is larger than a first threshold value. The computer device may obtain a sum of memory resource values occupied by each background application. When the sum of the memory resource values occupied by the background application programs is not less than a first threshold value, the kernel space in the computer equipment can send a resource limiting instruction to the user space, so that the user space can release the system resources occupied by the background application programs according to the resource limiting instruction. The first threshold may be a value set by the computer device or a value set by a user, for example, 60% of the total memory resource value of the computer device.

(3) The current CPU temperature is above the second threshold. The computer equipment can also monitor the temperature of the CPU in real time, and when the temperature of the CPU is higher than a preset second threshold value, the application program in the computer equipment is judged to consume a large amount of system resources, so that the computer equipment generates heat. The kernel space in the computer equipment can send a resource limiting instruction to the user space, so that the user space can release system resources occupied by the background application program according to the resource limiting instruction. The second threshold may be a value set by a computer device or a value set by a user, for example, 85 ℃.

According to the method, the computer equipment can detect the state of the computer equipment and send the resource limiting instruction, the situation that the foreground application program runs slowly due to insufficient available system resources is reduced, and the running smoothness of the computer equipment is improved.

In one embodiment, the method further comprises:

step 308, set resource priority for the background application.

In step 310, if it is detected that the background application program and the foreground application program have at least one of a communication mechanism and a synchronization mechanism, the resource priority of the background application program is increased.

The computer device may set a resource priority for the application. The computer device can set resource priority to the application program according to the type of the application program, the use frequency of the application program and the like. The resource priority is a limit level of resources available to the application, and if the resource priorities corresponding to the applications are different, the limit levels of the resources available to the applications are different. The higher the priority of the resource corresponding to the application, the less the limitation on the resources available to the application. The usable resources include: CPU resources, memory resources, I/O resources, and network resources. For example, the computer device may set a 5-level priority for the application including: stage 1, stage 2, stage 3, stage 4, and stage 5. Wherein, the 1 st priority is the highest, and the 5 th priority is the lowest. When the application program is in priority level 1, the usable proportion of each resource is 80%, that is, the usable CPU resource is 80% of the total CPU resource, the usable memory resource is 80% of the total memory resource, the usable I/O resource is 80% of the total I/O resource, and the usable network resource is 80% of the total network resource. When the application program is in the priority level 2, the usable proportion of each resource is 60 percent; when the application program is in the 3 rd priority level, the usable proportion of each resource is 40 percent; when the application program is in the 4 th priority level, the usable proportion of each resource is 20 percent; when the application is in priority 5, the proportion of each resource available is 10%.

The interprocess communication mechanism of the application program comprises socket, binder, shared memory and the like. Two programs on the network effect the exchange of data via a bidirectional communication link, one end of which is called a socket. Binder is an interprocess communication mechanism that provides remote procedure call functionality. Shared memory is a very efficient way to allow two unrelated processes to access the same logical memory, and shared memory is a very efficient way to share and transfer data between two running processes, and memory shared between different processes is usually arranged as the same physical memory. The inter-process synchronization mechanism of the application program means that in concurrent programming, access of processes to common variables must be restricted, and the restriction is called synchronization. In an operating system, the synchronization mechanism for user mode (user mode) may be implemented by calling a futex system call. The synchronization mechanism includes a semaphore, a mutex, etc. When the process of the background application program with any synchronization mechanism existing with the process of the foreground application program is detected through the futex system call, the detected background application program can be used as the depended application program. When the background application program and the foreground application program have one or more of a communication mechanism and a synchronization mechanism, the background application program can be regarded as a depended application program of the foreground application program, namely the foreground application program can be executed smoothly only by calling data of the background application program.

In general, a computer device sets a higher priority for resources of a foreground application and a lower priority for resources of a background application. When the computer device detects that the background application program is the application program depended on by the foreground application program, whether the resource priority of the background application program is the same as the resource priority of the foreground application program can be detected, and if the resource priority of the background application program is lower than the resource priority of the foreground application program, the resource priority of the background application program can be improved to the resource priority of the foreground application program by the computer device.

According to the method, when the background application program is detected to be the application program depended by the foreground application program, the resource priority of the background application program can be improved, the available resources of the background application program are increased, and the speed of the background application program responding to the foreground application program is increased.

In one embodiment, further comprising: and when detecting that the foreground application program finishes the dependence on the background application program, reducing the resource priority of the background application program. And when the background application program is not the application program depended by the foreground application program any more, restoring the resource priority of the background application program to the lower resource priority before adjustment.

In one embodiment, resource limiting the background application comprises: and freezing the background application program, and forbidding the background application program to use system resources.

The method further comprises the following steps:

in step 312, if a wake-up message for the background application program in the frozen state is received, a wake-up duration corresponding to the background application program is obtained.

And step 314, awakening the background application program in the frozen state when the time difference between the current time and the last awakened time of the background application program is not less than the awakening time.

The computer device may also resource limit the application, wherein a level of resource limit for the application may be determined based on a length of time the application enters the background. The longer the application enters the background, the higher the level of resource restriction on the application. When the computer equipment limits the resources of the application program, if the application program is switched to a process deep freezing mode, the application program is in a freezing state. When an application is in a frozen state, the application cannot use system resources and therefore cannot respond to communication messages of other applications. The freeze wakeup duration is a time difference for waking up the application program from the frozen state twice, which is preset by the computer device.

When the computer device receives a communication message or a system message for the application program in the frozen state, the computer device can be switched from the frozen state to a state in which system resources can be used, so that the application program can respond to the communication message or the system message. The state that the application program is switched from the freezing state to the usable system resource can be a state that the application program is switched from the process freezing state to the CPU restricted sleep state, so that the application program can use the system resource. The computer device can also unfreeze the application program, and the application program is not limited to using system resources.

Upon receiving a wake-up message for a background application in a frozen state, the computer device does not wake-up the background application each time a wake-up message is received. The computer device may compare the time difference between the current time and the last wake-up time of the background application with the wake-up duration. And if the time difference is greater than or equal to the awakening duration, the computer equipment immediately awakens the background application program according to the awakening message. If the time difference is smaller than the awakening time length, the computer equipment awakens the background application program when the time difference between the current time and the last awakened time of the background application program is equal to the awakening time length. That is, when detecting that the time difference between the current time and the last time when the application program is awakened is smaller than the awakening time, the computer device accumulates the awakening messages received in the awakening time, and when the time difference between the current time and the last time when the background application program is awakened is equal to the awakening time, awakens the background application program according to the accumulated awakening messages. If the wake-up message is not received within the wake-up duration after the last application is woken up, the computer device may immediately wake up the background application when the wake-up message is received after the wake-up duration is exceeded.

In general, in order to save power consumption of a computer device and increase available resources of a foreground application, the resources available to the background application are limited, for example, the background application is frozen. When the computer equipment receives the awakening message of the background application program, the background application program needs to be awakened, otherwise, the background application program generates no-response errors, but the frequent awakening of the background application program can cause the resource limit rate of the computer equipment to the background application program to be reduced, and the available resources of the foreground application program cannot be improved.

According to the method in the embodiment of the application, the computer equipment can set the wake-up duration for the application program in the frozen state, so that the application program is not frequently woken up to waste the power consumption of the computer equipment, and the problem that the application program is not responded after being in the frozen state for a long time is solved.

In one embodiment, the method further comprises:

in step 316, if a termination command for the background application program in the frozen state is received, the background application program is thawed and the background application program is set to the unfreezable state.

And step 318, closing the background application program according to the termination command.

If the resources of the computer equipment are in short supply, the computer equipment sends a termination command to the application program in the frozen state, closes the application program in the frozen state and releases the system resources occupied by the application program. However, when the application program is in the frozen state, the application program cannot receive any message, and even if the application program in the frozen state is woken up, the application program can be quickly restored to the frozen state after the application program is woken up, so that the computer device cannot close the application program in the frozen state. Typically, a computer device will use two sets of code to terminate an application, one for terminating frozen state applications and the other for terminating other applications.

When the computer equipment receives a termination command for an application program in a frozen state, if the application program is detected to be in the frozen state of the frozen state, the application program in the frozen state is unfrozen, and the unfrozen application program is set to be in a non-unfrozen state, the unfrozen application program can correctly respond to the termination command, namely the unfrozen application program can be closed. The unfreezing of the application program can be to not limit the system resource used by the application program, or to switch the application program from a state of not using the system resource to a state of using the system resource, such as to switch the application program to a CPU limited sleep mode.

According to the method, the application program in the frozen state can be safely terminated, the situation that the application program cannot be terminated is avoided, the computer equipment can terminate the application program in the frozen state and other application programs according to a uniform termination instruction, the compatibility of the application program in the frozen state and other application programs is achieved, the difficulty in software development is reduced, and the mobile operating system is convenient to maintain.

It should be understood that, although the steps in the above-described flowcharts are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least a portion of the steps in the above-described flowcharts may include multiple sub-steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of performing the sub-steps or the stages is not necessarily sequential, but may be performed alternately or alternatingly with other steps or at least a portion of the sub-steps or stages of other steps.
