图2为一个实施例中计算机设备的部分架构图。如图2所示，计算机设备的架构***中包括Java空间层210、本地框架层220以及内核(Kernel)空间层230。Java空间层中包括冻结和解冻模块212，上述冻结和解冻模块212用于实现对各个应用程序的冻结策略，例如对后台耗电的应用程序进行冻结等。2 is a partial architectural diagram of a computer device in an embodiment. As shown in FIG. 2, the architecture of the computer device includes a Java spatial layer 210, a local framework layer 220, and a Kernel space layer 230. The freeze and thaw module 212 is included in the Java space layer. The freeze and thaw module 212 is used to implement a freeze policy for each application, such as freezing the application that consumes the background.

本地框架层220中包括资源优先级和限制管理模块222、平台冻结管理模块224。上述资源优先级和限制管理模块222可对不同的应用程序进行不同的资源限制，使不同的应用程序处于不同的资源优先级中。资源优先级和限制管理模块222还可根据上层的需求调整应用程序的资源优先级，使得计算机设备可合理应用程序可使用资源。平台冻结管理模块224可根据应用程序进入后台的时长来确定对进程应用程序进行资源限制的等级，平台冻结管理模块224可预设不同的资源限制的等级，应用程序进入后台的时间越长，平台冻结管理模块224对应用程序进行资源限制的等级越高，即对应用程序的资源限制程度越高。可选地，上述资源限制等级可包括：CPU限制睡眠模式、CPU冻结睡眠模式和进程深度冻结模式。上述CPU限制睡眠模式是指对应用程序的进程可使用的中央处理器(Central Processing Unit，CPU)资源进行限制，使应用程序的进程可使用较少的CPU资源；在CPU限制睡眠模式下还可进一步限制应用程序的进程可使用的网络资源和输入/输出接口(input/output，I/O)资源。CPU冻结睡眠模式是指禁止应用程序的进程使用CPU资源、网络资源和I/O资源，但对应用程序的进程占用的内存资源不进行回收，上述CPU 冻结模式是对应用程序可使用资源的深度限制模式。CPU冻结睡眠模式是指禁止应用程序的进程使用CPU资源、网络资源和I/O资源，同时回收应用程序的进程占用的内存资源。其中，本地框架层220的接口模块包含开发给上层的binder接口，上层的框架或应用程序通过上述binder接口可发送资源限制指令给资源限制管理模块222、发送冻结指令给平台冻结管理模块224。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 can perform different resource restrictions on different applications, so that different applications are in different resource priorities. The resource priority and restriction management module 222 can also adjust the resource priority of the application according to the needs of the upper layer so that the computer device can use the resource reasonably. The platform freeze management module 224 can determine the level of resource restriction on the process application according to the duration of the application entering the background. The platform freeze management module 224 can preset different resource limit levels, and the longer the application enters the background, the platform The higher the level of resource restriction on the application by the freeze management module 224, the higher the resource limit on the application. Optionally, the foregoing resource restriction level may include: a CPU restricted sleep mode, a CPU freeze sleep mode, and a process deep freeze mode. The CPU limit sleep mode refers to limiting the central processing unit (CPU) resources that can be used by the application process, so that the application process can use less CPU resources; in the CPU limited sleep mode, Further limit the network resources and input/output (I/O) resources available to the application's processes. CPU freeze sleep mode means that the process of the application is prohibited from using CPU resources, network resources and I/O resources, but the memory resources occupied by the application process are not recycled. The above CPU freeze mode is the depth of resources available to the application. Restricted mode. CPU freeze sleep mode refers to prohibiting the application process from using CPU resources, network resources, and I/O resources, while reclaiming the memory resources occupied by the application's processes. The interface module of the local framework layer 220 includes a binder interface developed to the upper layer. The upper framework or application 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.

内核空间层230中包括UID管理模块231、Cgroup模块232、binder管控模块233、进程内存回收模块234和超时冻结退出模块235。当前对应用程序的进程管理是基于进程识别号(Process Identification，PID)来实现的，进程与应用程序没有对应，不利于统一管理一个应用程序的所有进程对应的资源。上述UID管理模块231可通过应用程序的用户身份标识(User Identifier，UID)来管理应用程序的资源，也可通过应用程序的UID对应用程序进行冻结。Cgroup模块232可提供基于CPU、CPUSET、内存(memory)、I/O资源和Net相关的资源限制机制。binder管控模块233可用于限制后台进程间binder通信的优先级。进程内存回收模块234用于实现进程深度冻结模式，在进程进入进程深度冻结模式时，释放掉进程的文件区，从而实现节省内存，加快进程对应的应用程序下次启动时的速度。超时冻结退出模块235用于解决进程在冻结超时发生异常的问题。The kernel space layer 230 includes a UID management module 231, a Cgroup module 232, a binder management module 233, a process memory recovery module 234, and a timeout freeze exit module 235. The current process management of the application is implemented based on the process identification (PID). The process does not correspond to the application, which is not conducive to unified management of resources corresponding to all processes of an application. The UID management module 231 can manage the resources of the application through the User Identifier (UID) of the application, and can also freeze the application by the UID of the application. The Cgroup module 232 can provide resource-based mechanisms based on CPU, CPUSET, memory, I/O resources, and Net. The binder management module 233 can be used to limit the priority of the binder communication between background processes. The process memory recovery module 234 is configured to implement the process deep freeze mode. When the process enters the process deep freeze mode, the file area of the process is released, thereby saving memory and speeding up the next time the application corresponding to the process starts. The timeout freeze exit module 235 is used to solve the problem that the process has an abnormality in the freeze timeout.

通过上述的架构，可实现本申请各个实施例中的信息处理方法。Through the above architecture, the information processing method in various embodiments of the present application can be implemented.

图3为一个实施例中信息处理方法的流程图。如图3，一种信息处理方法，包括：3 is a flow chart of an information processing method in an embodiment. As shown in FIG. 3, an information processing method includes:

操作302，在内核空间中获取进程事件，并对进程事件分类，得到分类后的进程事件；分类后的进程事件包括进程通信事件，进程通信事件是根据进程间的通信生成的。In operation 302, a process event is obtained in the kernel space, and the process event is classified to obtain a classified process event; the classified process event includes a process communication event, and the process communication event is generated according to communication between processes.

通常情况下，在Linux***中可将***分为内核空间和用户空间两部分。其中，内核空间中存放内核代码和数据，用户空间中存放应用程序的代码和数据。内核空间的权限较高，用户空间的权限较低。Generally, in Linux systems, the system can be divided into two parts: kernel space and user space. Among them, the kernel space stores the kernel code and data, and the user space stores the application code and data. Kernel space has higher permissions and user space has lower permissions.

进程是一个具有一定独立能力的程序关于某个数据集合的一次运行活动，一个应用程序在运行时包括多个进程。在进程运行的过程中，由于进程间通信机制和进程状态的改变会产生进程事件。在内核空间中可对进程产生的进程事件进行分类，得到分类后的进程事件。上述分类后的进程事件可包括进程通信事件和进程状态事件。上述进程通信事件是根据进程间通信产生的事件，上述进程状态事件是由于进程状态变化产生的事件。A process is a run-time activity of a program with certain independence about a data set. An application includes multiple processes at runtime. During the running of the process, process events are generated due to changes in the inter-process communication mechanism and process state. The process events generated by the process can be classified in the kernel space to obtain the classified process events. The above classified process events may include process communication events and process status events. The above process communication event is an event generated according to inter-process communication, and the above process status event is an event generated due to a change in the process state.

操作304，内核空间将分类后的进程事件和对应的进程异步传送给用户空间，以使用户空间根据进程通信事件调整对进程的资源限制。 Operation 304, the kernel space asynchronously transfers the classified process event and the corresponding process to the user space, so that the user space adjusts the resource limit of the process according to the process communication event.

用户空间将进程产生的进程事件分类得到分类后的进程事件后，可将分类后的进程时间异步传送给用户空间。其中，内核空间与用户空间主要通过异步netlink的方式进行通信，内核空间在与用户空间进行通信时，可遵循内核空间与用户空间约定的包结构，并根据不同的进程事件生成不同的数据。内核空间在将分类后的进程事件和对应的进程异步传送给用户空间时，可将分类后的进程事件、事件对应的进程和事件发生的原因传送给用户空间。例如，后台进程接收到前台进程的通信消息后，可生成socket到达事件，则内核空间可将上述socket到达事件、后台进程的UID和socket到达事件发生的原因：后台进程接收到前台进程的通信消息传送给用户空间。After the user space classifies the process events generated by the process to obtain the classified process events, the classified process time can be asynchronously transmitted to the user space. Among them, kernel space and user space mainly communicate through asynchronous netlink. When communicating with user space, kernel space can follow the package structure agreed by kernel space and user space, and generate different data according to different process events. The kernel space can transfer the classified process event, the process corresponding to the event, and the cause of the event to the user space when the classified process event and the corresponding process are asynchronously transmitted to the user space. For example, after the background process receives the communication message of the foreground process, the socket arrival event may be generated, and the kernel space may cause the socket arrival event, the UID of the background process, and the socket arrival event to occur: the background process receives the communication message of the foreground process. Transfer to user space.

用户空间在接收到内核空间异步传送的数据后，可对接收到的数据进行解析，获取进程底层的变化，再根据进程底层的变化及时更新对进程的资源限制。其中，用户空间对进程的资源限制主要包括对进程可使用的CPU资源、I/O资源、网络资源、内存资源等进行限制，使得各进程之间的资源可以合理调配。After receiving the data asynchronously transmitted by the kernel space, the user space can parse the received data, obtain the underlying changes of the process, and then update the resource limit of the process according to the change of the underlying process. The resource limitation of the user space to the process mainly includes limiting the CPU resources, I/O resources, network resources, and memory resources that can be used by the process, so that the resources between the processes can be properly allocated.

在当前主流的移动操作***中，对应用程序可使用资源的限制主要通过用户空间来进行，用户空间可通过Cgroup机制将不同等级资源对应的应用程序放入不同的资源组中。通过用户空间可调用丰富的库和丰富的策略来判断对应用程序可使用资源的限制，但由于用户空间权限较低，仅通过用户空间的信息和策略无法根据应用程序底层的变化及时更新对应用程序的资源限制等级。In the current mainstream mobile operating system, the limitation of the resources that can be used by the application is mainly performed by the user space, and the user space can put the applications corresponding to the different level resources into different resource groups through the Cgroup mechanism. User space can call rich libraries and rich policies to determine the restrictions on the resources available to the application. However, due to the low user space permissions, only the user space information and policies cannot update the application according to the changes of the underlying application. The resource limit level of the program.

本申请实施例中方法，内核空间将进程事件异步传送给用户空间，提高了用户空间获取进程底层变化信息的效率。通过内核空间对进程事件进行分类，用户空间决策进程可用资源的方法，可兼容用户空间丰富的策略和内核空间可及时获取进程状态变化的特点，在对进程进行资源限制时，可避免进程由于资源限制导致的状态异常的问题。In the method in the embodiment of the present application, the kernel space asynchronously transmits the process event to the user space, thereby improving the efficiency of the user space to obtain the underlying change information of the process. The process of classifying process events through kernel space, the method of available resources in the user space decision process, and the compatibility of user space rich strategy and kernel space can timely acquire the characteristics of process state changes. When resources are restricted to processes, processes can be avoided due to resources. Limit the problem that caused the state to be abnormal.

在一个实施例中，用户空间根据进程通信事件调整对进程的资源限制包括以下方法中至少一种：In one embodiment, the user space adjusts resource limits to the process based on the process communication event including at least one of the following methods:

(1)用户空间根据binder启动事件提升进程的资源优先级。(1) The user space raises the resource priority of the process according to the binder startup event.

(2)用户空间根据binder空闲事件降低进程的资源优先级。(2) User space reduces the resource priority of the process according to the binder idle event.

(3)用户空间根据socket到达事件提升进程的资源优先级。(3) User space according to the socket arrival event to promote the resource priority of the process.

进程间的通信事件包括binder启动事件、binder空闲事件和socket到达事件。用户空间可根据接收到的进程通信事件的不同调整对进程的资源限制。Inter-process communication events include binder start events, binder idle events, and socket arrival events. User space adjusts resource limits for processes based on the received process communication events.

binder是移动操作***中重要的进程间通信机制。不同进程之间的通信大多为binder通信。其中，内核空间可对binder通信设定两个事件：binder启动事件和binder空闲事件。其中，binder启动事件是指进程一旦接收到其他进程发送的binder时会立即产生binder启动事件。binder空闲事件是指进程在预设时长内后不再有binder会话存货则会产生binder空闲事件。当进程产生到binder启动事件时，表示进程与其他进程之间有通信，用户空间可提升上述进程的资源优先级，增加进程可使用的资源。当进程产生binder空闲事件时，表示进程与其他进程之间没有通信，用户空间可降低上述进程的资源优先级，减少进程可使用的资源。Binder is an important interprocess communication mechanism in mobile operating systems. Most of the communication between different processes is binder communication. Among them, the kernel space can set two events for the binder communication: the binder startup event and the binder idle event. Among them, the binder startup event means that the process will immediately generate a binder startup event once it receives the binder sent by other processes. The binder idle event means that the process no longer has a binder session inventory after the preset time period, and a binder idle event is generated. When the process generates a binder startup event, it indicates that there is communication between the process and other processes. The user space can increase the resource priority of the above process and increase the resources available to the process. When a process generates a binder idle event, it indicates that there is no communication between the process and other processes. The user space can reduce the resource priority of the above process and reduce the resources available to the process.

socket也是移动操作***中广泛使用的通信机制。例如，在Android***中就经常使用socket机制。内核空间可对socket通信设置一个事件：socket到达事件。其中，socket到达事件是进程一旦接受到其他进程发送的socket时，会产生socket到达事件。当进程产生socket到达事件时，表示进程与其他进程之间有通信，用户空间可提升上述进程的资源优先级，增加进程可使用的资源。通过socket到达事件，可解决通信类应用程序在资源被限制时无法及时接受到消息的问题。Sockets are also a widely used communication mechanism in mobile operating systems. For example, the socket mechanism is often used in Android systems. Kernel space sets an event for socket communication: the socket arrives at the event. The socket arrival event is that when the process accepts the socket sent by another process, a socket arrival event is generated. When a process generates a socket arrival event, it indicates that there is communication between the process and other processes. The user space can increase the resource priority of the above process and increase the resources available to the process. The arrival of the event through the socket can solve the problem that the communication application cannot receive the message in time when the resource is restricted.

内核空间中可设置进程名单，仅在进程名单中进程在接收到binder或socket时，会产生对应的进程通信事件。The process list can be set in the kernel space. Only when the process receives the binder or socket in the process list, the corresponding process communication event will be generated.

上述资源优先级即为对进程可使用的资源的限制等级。用户空间可对应用程序设置不同的资源优先级，上述资源优先级不同时，对应用程序的进程可使用资源的限制也不同，即用户空间通过对应用程序设置资源优先级，可实现对应用程序的进程设置资源优先级。用户空间可将不同资源优先级的应用程序放置于不同的资源组中，方便用户空间对应用程序的管理。用户空间通过对应用程序资源优先级包括：用户空间设置应用程序对应的资源优先级，其中资源优先级对应应用程序可使用总资源的大小。例如，用户空间设置应用程序的资源优先级为1级、应用程序可使用总资源的80％，则应用程序可分别使用CPU资源的80％、内存资源的80％、I/O资源的80％、网络资源的80％。用户空间还可对应用程序可使用的资源分别设置资源优先级，包括CPU资源优先级、内存资源优先级、I/O资源优先级和网络资源优先级。一个应用程序对应的各个资源优先级可不同，例如，应用程序对应的CPU资源优先级为1级、可使用总CPU资源的90％；对应的内存资源优先级为2级，可使用总内存资源的75％；对应的I/O资源的优先级为4级，可使用总I/O资源的30％；对应的网络资源的优先级为2级，可使用总网络资源的80％。The above resource priority is the level of restriction on the resources available to the process. The user space can set different resource priorities for the application. When the above resource priorities are different, the restrictions on the resources that can be used by the application process are different, that is, the user space can implement the application by setting the resource priority to the application. The process sets the resource priority. User space allows applications with different resource priorities to be placed in different resource groups, facilitating user space management of the application. The user space prioritizes the application resource includes: the user space sets the resource priority corresponding to the application, wherein the resource priority corresponds to the size of the total resource that the application can use. For example, if the user space setting application has a resource priority of 1 and the application can use 80% of the total resources, the application can use 80% of the CPU resources, 80% of the memory resources, and 80% of the I/O resources, respectively. 80% of network resources. User space can also set resource priorities for resources that can be used by applications, including CPU resource priority, memory resource priority, I/O resource priority, and network resource priority. The priority of each resource corresponding to an application may be different. For example, the CPU resource priority of the application is 1 level, 90% of the total CPU resources can be used; the corresponding memory resource priority is 2, and the total memory resource can be used. 75%; the corresponding I/O resource has a priority of 4, which can use 30% of the total I/O resources; the corresponding network resource has a priority of 2, and can use 80% of the total network resources.

本申请实施例中方法，用户空间可通过接收到的进程事件来调整进程对应的资源优先级，用户空间对进程的资源限制更加迅速和准确，提高了用户空间对进程的资源限制的准确率。In the method in the embodiment of the present application, the user space can adjust the resource priority corresponding to the process by using the received process event, and the resource limitation of the process in the user space is more rapid and accurate, and the accuracy of the resource limitation of the user space to the process is improved.

在一个实施例中，提升进程的资源优先级包括：In one embodiment, the resource priority of the promotion process includes:

(1)若检测到待提升资源优先级的进程为后台进程，获取当前运行的前台进程的资源优先级。(1) If the process of the priority of the resource to be upgraded is detected as a background process, the resource priority of the currently running foreground process is obtained.

(2)提升后台进程的资源优先级，提升后后台进程的资源优先级不高于前台进程的资源优先级。(2) The resource priority of the background process is increased. After the promotion, the resource priority of the background process is not higher than the resource priority of the foreground process.

用户空间可对不同的应用程序分配不同的资源优先级，则同一个应用程序对应的进程的资源优先级相同，不同应用程序对应的进程的资源优先级可不同。用户空间对进程提升资源优先级时，若检测到带提升资源优先级的进程为后台进程，则获取当前运行的前台进程的资源优先级。The user space can assign different resource priorities to different applications, and the processes corresponding to the same application have the same resource priority, and the processes corresponding to different applications can have different resource priorities. When the user space is used to raise the priority of the resource, if the process with the priority of the elevated resource is detected as the background process, the resource priority of the currently running foreground process is obtained.

为避免后台进程与前台进程抢占资源，通常情况下，可设置后台进程的资源优先级低于前台进程的资源优先级，则后台进程可用的资源低于前台进程可用的资源。在获取前台进程的资源优先级后，用户空间可提升后台进程的资源优先级时，使后台进程的资源优先级低于前台进程的资源优先级。其中，用户空间在提升后台进程的资源优先级时，包括：提升后台进程的总资源优先级，即后台进程可使用的各项资源的优先级均可提升；或提升后台进程的某一项或多项资源的优先级，例如提高后台进程的CPU资源优先级，使得后台进程可使用的CPU资源增加。To prevent the background process and the foreground process from preempting resources, you can set the resource priority of the background process to be lower than the resource priority of the foreground process. The resources available to the background process are lower than the resources available to the foreground process. After the resource priority of the foreground process is obtained, the user space can increase the resource priority of the background process, so that the resource priority of the background process is lower than the resource priority of the foreground process. The user space increases the priority of the background process, including: increasing the total resource priority of the background process, that is, the priority of each resource that can be used by the background process can be improved; or upgrading one of the background processes or The priority of multiple resources, such as increasing the CPU resource priority of the background process, makes the CPU resources available to the background process increase.

本申请实施例中方法，在提升进程的资源优先级时，保证前台进程的资源优先级高于后台进程的资源优先级，可避免后台进程的资源优先级高于前台进程的资源优先级导致前台进程的资源被抢占，前台进程运行缓慢的问题。In the method of the embodiment of the present application, when the resource priority of the process is increased, the priority of the resource of the foreground process is higher than that of the background process, and the priority of the resource of the background process is higher than that of the foreground process. The process resources are preempted and the foreground process is running slowly.

在一个实施例中，分类后的进程事件还包括进程状态事件，进程状态事件是根据进程在生命周期中的变化生成的；用户空间可根据进程状态事件更新用户空间中进程的进程信息。In one embodiment, the classified process event further includes a process state event, and the process state event is generated according to a change of the process in the life cycle; the user space may update the process information of the process in the user space according to the process state event.

内核空间还可监控进程在生命周期中变化，根据进程在生命周期的变化生成进程状态事件。当进程在创造、退出、更改UID时都会产生对应的进程状态事件，上述进程状态事件表示进程状态发生了变化。用户空间在接收到进程状态事件时，可根据上述进程状态事件维护对进程和应用程序状态的更新。本申请实施例中方法，用户空间在接收到进程状态事件后，可根据进程状态事件更新进程及进程状态，使得用户空间可维护进程的更新，使得用户空间在对进程进行资源限制时，无需查询更新进程及进程状态，提高了用户空间的效率。Kernel space also monitors the process's lifecycle changes and generates process state events based on changes in the lifecycle of the process. When a process creates, exits, or changes a UID, it generates a corresponding process state event. The process state event indicates that the process state has changed. When user space receives a process state event, it can maintain updates to the process and application state based on the process state events described above. In the method of the embodiment of the present application, after receiving the process state event, the user space may update the process and the process state according to the process state event, so that the user space can maintain the update of the process, so that the user space does not need to query when the resource is restricted to the process. Update the process and process state to improve the efficiency of user space.

在一个实施例中，上述方法还包括：In an embodiment, the above method further includes:

操作306，用户空间获取进程进入后台的时长，当进程进入后台的时长达到预设时长时，对进程进行冻结；对进程进行冻结是指禁止进程使用***资源。In operation 306, the user space acquires the duration of the process entering the background. When the duration of the process entering the background reaches a preset duration, the process is frozen; freezing the process refers to prohibiting the process from using system resources.

通常情况下，计算机设备为节省功耗，会对进入后台的进程进行资源限制，节省计算机设备的功耗。其中，计算机设备对进程进行资源限制可包括：普通限制模式、深度限制模式和冻结模式。其中，普通限制模式是对进程可使用的CPU资源进行限制，相应的也会限制进程可使用的其他资源，如I/O资源、网络资源等；深度限制模式是禁止进程使用CPU资源、网络资源和I/O资源进行限制，但对进程使用的内存资源不进行限制。冻结模式是进程使用所有的***资源，即禁止进程使用CPU资源、网络资源和I/O资源，回收进程占用的内存资源等。用户空间可获取进程进入后台的时长，当进程进入后台的时长达到预设时长，则可判定进程长时间未启用，对进程进行冻结，释放进程占用的资源。In general, computer equipment saves power, limits resources to processes entering the background, and saves power consumption of computer equipment. The resource limitation of the process by the computer device may include: a normal restriction mode, a depth restriction mode, and a freeze mode. The common restriction mode is to limit the CPU resources that the process can use, and correspondingly limit other resources that the process can use, such as I/O resources and network resources. The deep limit mode prohibits the process from using CPU resources and network resources. There are restrictions on I/O resources, but there are no restrictions on the memory resources used by the process. The freeze mode is that the process uses all system resources, that is, prohibits the process from using CPU resources, network resources, and I/O resources, and reclaims the memory resources occupied by the process. The user space can obtain the length of time that the process enters the background. When the process reaches the background for a preset period of time, it can be determined that the process is not enabled for a long time, and the process is frozen to release the resources occupied by the process.

本申请实施例中方法，当进程进入后台的时长达到预设时长时，可对进程进行冻结，释放进程占用的***资源，使得计算机设备可合理调控进程使用的资源，降低计算机设备的功耗。In the method of the embodiment of the present application, when the duration of the process entering the background reaches a preset duration, the process may be frozen, and the system resources occupied by the process are released, so that the computer device can reasonably regulate the resources used by the process and reduce the power consumption of the computer device.

操作308，当用户空间接收到处于冻结状态的进程对应的进程通信事件时，将处于冻结状态的进程唤醒并调整对进程的资源限制。Operation 308, when the user space receives the process communication event corresponding to the process in the frozen state, wake up the process in the frozen state and adjust the resource limit of the process.

当进程处于冻结状态时，进程不能使用***资源。当用户空间接收到对处于冻结状态的进程对应的进程通信事件时，可将处于冻结状态的进程唤醒，使得进程可使用***资源来响应上述进程通信事件。其中，用户空间将处于冻结状态的进程唤醒包括：将进程由冻结模式切换到普通限制模式，使得进程可使用***资源。用户空间在将处于冻结状态的进程唤醒后，还可根据接收到进程通信事件的类型调整上述进程的资源优先级。When a process is frozen, the process cannot use system resources. When the user space receives a process communication event corresponding to the process in the frozen state, the process in the frozen state may be awakened, so that the process can use the system resource to respond to the process communication event. The user space wakes up the process in the frozen state, including: switching the process from the freeze mode to the normal limit mode, so that the process can use the system resources. After waking up the process in the frozen state, the user space can also adjust the resource priority of the process according to the type of the process communication event received.

本申请实施例中方法，用户空间在接收到对处于冻结状态的进程对应的进程通信事件时，可将上述处于冻结状态的进程唤醒再调整对上述进程的资源限制，使得已冻结进程可及时响应其他进程的通信消息，提高了用户空间对进程的资源控制率。In the method of the embodiment of the present application, when receiving the process communication event corresponding to the process in the frozen state, the user space may wake up the process in the frozen state and adjust the resource limit of the process, so that the frozen process can respond in time. Communication messages of other processes improve the resource control rate of the user space to the process.

操作310，当用户空间接收到对处于冻结状态的进程的终止命令时，将进程解冻，并将解冻后进程设置为不可冻结状态，根据终止命令终止解冻后进程。In operation 310, when the user space receives the termination command for the process in the frozen state, the process is thawed, and the thawed process is set to the unfreeze state, and the thawed process is terminated according to the termination command.

若计算机设备资源紧缺，计算机设备会对已冻结的进程发送终止命令，关闭上述已冻结的进程，释放已冻结的进程占用的资源。但当进程处于冻结状态时，进程无法接收到任何消息，即使处于冻结状态的进程被唤醒，唤醒后进程也会快速恢复到冻结状态，因此计算机设备无法关闭处于冻结状态的进程。通常情况下，计算机设备会使用两套代码来终止进程，其中一套代码用于终止未冻结进程，另一套代码用于终止已冻结进程。If the computer device resources are scarce, the computer device sends a termination command to the frozen process, shutting down the frozen process, and releasing the resources occupied by the frozen process. However, when the process is frozen, the process cannot receive any messages. Even if the process in the frozen state is woken up, the process will quickly return to the frozen state after waking up, so the computer device cannot close the process in the frozen state. Typically, a computer device uses two sets of code to terminate a process, one set of code to terminate the unfrozen process and another set of code to terminate the frozen process.

当计算机设备接收到对已冻结的进程的终止命令时，若检测到上述已冻结的进程处于冻结状态，对上述处于冻结状态的进程进行解冻，并将解冻后进程设置为不可冻结状态，则解冻后的进程可对上述终止命令正确响应，即上述解冻后的进程可被关闭。When the computer device receives the termination command for the frozen process, if it is detected that the frozen process is in a frozen state, the process in the frozen state is thawed, and the thawed process is set to a non-freeze state, then thawed The subsequent process can respond correctly to the above termination command, that is, the above thawed process can be closed.

本申请实施例中方法，通过对已冻结进程进行先解冻再终止的方法，可实现对已冻结进程的安全终止，避免出现进程无法终止的情况，计算机设备可根据统一的终止指令来终止已冻结进程和未冻结进程，实现了终止已冻结进程和终止未冻结进程的兼容性，减少了软件开发的困难，方便对移动操作***进行维护。The method in the embodiment of the present application can implement the method of first thawing and then terminating the frozen process to implement the secure termination of the frozen process, and avoid the situation that the process cannot be terminated. The computer device can terminate the frozen according to the unified termination instruction. The process and the unfrozen process realize the compatibility of terminating the frozen process and terminating the unfrozen process, reducing the difficulty of software development and facilitating the maintenance of the mobile operating system.
