This keyword is information common to the process information of the daemon that can be resource limited. The electronic device may detect one or more field information preset in the process information to determine whether the detected field information includes the corresponding keyword. For example, it can detect whether the process name and the one or more fields such as UID contain corresponding keywords.
操作306,当包含关键字时,对守护进程进行资源限制。 Operation 306, when the keyword is included, resource limits are imposed on the daemon.
可选地,当检测到进信息中包含预设的关键字时,对相应的守护进程进行资源限制。其中,资源包括CPU资源、CPUSET资源、内存资源、I/O资源和Net相关的资源等。电子设备可对上述资源中的一种或多种进行限制,以防止守护进程占据较多的资源而影响前台进程的处理效率。Optionally, when the preset information is included in the incoming information, the resource is restricted to the corresponding daemon. The resources include CPU resources, CPUSET resources, memory resources, I/O resources, and Net related resources. The electronic device may limit one or more of the above resources to prevent the daemon process from occupying more resources and affecting the processing efficiency of the foreground process.
在一个实施例中,对守护进程进行资源限制,包括:对守护进程所占用的CPU资源和I/O资源进行限制。In one embodiment, resource limits are imposed on the daemon, including: limiting CPU resources and I/O resources occupied by the daemon.
可选地,由于通常这类守护进程对CPU资源和I/O资源的占用较多,电子设备通过对这类资源进行CPU资源和I/O资源的限制,可进一步提高前台应用可使用的CPU资源和I/O资源,从而提高了前台应用的处理效率。Optionally, since such a daemon process generally occupies more CPU resources and I/O resources, the electronic device can further improve the CPU that can be used by the foreground application by limiting CPU resources and I/O resources of such resources. Resources and I/O resources improve the processing efficiency of the foreground application.
本实施例所提供的进程处理方法,电子设备通过对守护进程进行关键字的检测,可提高对检测出所存在的比较隐蔽的守护进程的检测效率,并对检测出的进程信息中包含相应的关键字的守护进程进行资源限制,防止其对更多资源的占用,使更多的资源向前台应用所倾斜,提高前台应用的处理效率通过进程。In the process processing method provided by the embodiment, the electronic device can improve the detection efficiency of detecting the relatively hidden daemon process by detecting the keyword of the daemon process, and include the corresponding key in the detected process information. The word daemon performs resource restrictions to prevent it from occupying more resources, so that more resources are tilted toward the foreground application, and the processing efficiency of the foreground application is improved through the process.
在一个实施例中,关键字包括第一关键字和第二关键字;操作304包括:检测进程信息中的进程名称是否包含第一关键字;检测进程信息中的用户身份标识UID是否包含第二关键字;操作306包括:当包含第一关键字和第二关键字时,对守护进程进行资源限制。In one embodiment, the keyword includes a first keyword and a second keyword; operation 304 includes: detecting whether the process name in the process information includes the first keyword; and detecting whether the user identity UID in the process information includes the second Keyword; operation 306 includes: resource limiting the daemon process when the first keyword and the second keyword are included.
电子设备需要检索的关键字包括两种,分别为第一关键字和第二关键字。第一关键字和第二关键字分别由预设长度的不同的数字、字母或其它字符等其中的一种或多种构成。第一关键字为对进程名称进行检测的关键字,第二关键字为对UID进行检测的关键字。The keywords that the electronic device needs to retrieve include two types, a first keyword and a second keyword. The first keyword and the second keyword are respectively composed of one or more of different numbers, letters or other characters of a preset length. The first keyword is a keyword that detects the process name, and the second keyword is a keyword that detects the UID.
电子设备可获取进程信息中的进程名称以及UID,并检测进程名称中是否包含第一关键字,以及UID中是否包含第二关键字。可选地,电子设备可同时进行第一关键字和第二关键字的检测,两者的检测顺序并没有必然的限定。当检测出进程名称中包含第一关键字,且UID中包含第二关键字时,电子设备可以对该守护进程进行资源限制。The electronic device can obtain the process name and the UID in the process information, and detect whether the process name includes the first keyword and whether the second keyword is included in the UID. Optionally, the electronic device can perform detection of the first keyword and the second keyword at the same time, and the detection order of the two is not necessarily limited. When it is detected that the process name includes the first keyword, and the UID includes the second keyword, the electronic device may perform resource limitation on the daemon.
本实施例中,电子设备通过在进程名称以及UID中进行关键字的检测,进一步提高了对可进行资源限制的守护进程的检测的准确性。In this embodiment, the electronic device further improves the accuracy of detecting the daemon process that can perform resource limitation by performing keyword detection in the process name and the UID.
在一个实施例中,在对守护进程进行资源限制之前,还包括:获取前台应用的应用类别,当应用类别为游戏类应用,执行对守护进程进行资源限制。In an embodiment, before the resource restriction is performed on the daemon, the method further includes: acquiring an application category of the foreground application, and performing resource limitation on the daemon when the application category is a game application.
可选地,电子设备可检测本机的前台应用的运行状态,当前台应用处于游戏运行状态时,可执行对守护进程进行资源限制的操作。电子设备可记录不同的应用所属的应用类别,应用类别可包括游戏应用、社交应用、地图导航应用、网购支付应用、通话通讯应用、浏览器应用等。电子设备可获取处于前台运行状态的应用的应用类别,处于前台运行的应用即为前台应用。当检测到前台应用为游戏应用时,电子设备可以执行对守护进程进行资源限制的操作。Optionally, the electronic device can detect an operating state of the front-end application of the local device, and when the current running application is in the running state of the game, perform a resource limiting operation on the daemon. The electronic device can record application categories to which different applications belong, and the application categories may include game applications, social applications, map navigation applications, online shopping payment applications, call communication applications, browser applications, and the like. The electronic device can obtain the application category of the application running in the foreground, and the application running in the foreground is the foreground application. When it is detected that the foreground application is a game application, the electronic device can perform a resource restriction operation on the daemon.
本实施例中,由于游戏类的应用在运行的过程中,通常需要占用较大的资源才能保持流畅的运行,而当存在隐藏在后台运行的守护进程时,也会占用一定的资源,影响游戏应用的运行效率,因此,当检测到前台应用为游戏应用时,电子设备可以对检测出的守护进程进行资源限制,可进一步提高游戏应用的运行效率。In this embodiment, since the application of the game class is in the process of running, it usually needs to occupy a large resource to maintain smooth running, and when there is a daemon hidden in the background, it also occupies certain resources and affects the game. The running efficiency of the application, therefore, when detecting that the foreground application is a game application, the electronic device can limit the resources of the detected daemon, which can further improve the operating efficiency of the game application.
在一个实施例中,对守护进程进行资源限制,包括:降低守护进程的优先级;根据降低后的优先级对守护进程进行资源限制。In one embodiment, resource limits are imposed on the daemon, including: reducing the priority of the daemon; and limiting resources to the daemon based on the reduced priority.
可选地,针对每个处于前后台运行的进程,电子设备设置了对应不同的优先级,不同的优先级对应不同的资源限制程度。优先级越高的进程,对其可使用的资源的限制程度越低。通常地,前台进程对应被设置了最高的优先级,且相对高于后台进程的优先级。同一个进程,处于前台运行时以及处于后台运行时的优先级不一定相同。且同一个后台进程,处于不同状态下的优先级也不一定相同。比如,同一后台进程,在不同的时刻,或者前台 进程不同时,该后台进程的优先级也不一定相同。Optionally, for each process running in the front background, the electronic device is set to correspond to different priorities, and different priorities correspond to different resource limitation levels. The higher the priority, the lower the limit on the resources available to it. Generally, the foreground process is set to the highest priority and is relatively higher than the priority of the background process. The same process, when running in the foreground and running in the background, does not have the same priority. And the same background process, the priority in different states is not necessarily the same. For example, when the same background process is different at different times or when the foreground process is different, the priority of the background process is not necessarily the same.
针对查询出的守护进程,电子设备可对其优先级进行调整,以降低该守护进程的优先级,并按照降低后的优先级来对该守护进程进行资源限制,以提高对守护进程的资源限制程度,使得更多的资源向前台应用倾斜。For the queried daemon, the electronic device can adjust its priority to lower the priority of the daemon, and limit the resource to the daemon according to the reduced priority to increase the resource limit on the daemon. The extent that more resources are tilted toward the foreground application.
举例来说,电子设备可按照优先级由高到低,分别设置优先级1至优先级5,共5级优先级,优先级越高的进程,对其可使用的资源的限制程度越低。当存在守护进程A的优先级为3级,且该守护进程A的进程信息中包含上述的关键字时,电子设备将该守护进程A的优先级由优先级3级调整至优先级4或优先级5级等,以保留更多的可用资源给前台应用使用,进一步提高前台应用的运行效率。For example, the electronic device can set priority 1 to priority 5 according to the priority, and the priority is 5 levels, and the higher the priority, the lower the limit on the resources that can be used. When the priority of the daemon A is 3, and the process information of the daemon A includes the above keywords, the electronic device adjusts the priority of the daemon A from the priority 3 to the priority 4 or preferentially. Level 5, etc., to retain more available resources for the foreground application to further improve the operational efficiency of the foreground application.
在一个实施例中,守护进程进行资源限制,包括:根据本地的资源利用率计算出对守护进程的限制程度;根据限制程度对守护进程进行资源限制。In one embodiment, the daemon process performs resource limitation, including: calculating a limit on the daemon process according to the local resource utilization rate; and limiting the resource to the daemon process according to the degree of restriction.
可选地,本地资源利用率包括CPU资源、I/O资源、内存资源等其中的一种或多种资源的利用率。资源利用率反映了电子设备的资源空闲状态,资源利用率越低,则相应的空闲的资源越多。电子设备可根据当前的资源利用率来计算出对守护进程的限制程度,使得当资源利用率越大的时候,对守护进程的限制程度越高,资源利用率越小,则对守护进程的限制程度也相应的越小。Optionally, the local resource utilization includes utilization of one or more resources of the CPU resource, the I/O resource, the memory resource, and the like. The resource utilization reflects the idle state of the resources of the electronic device, and the lower the resource utilization, the more idle resources are corresponding. The electronic device can calculate the limit on the daemon process according to the current resource utilization rate, so that when the resource utilization rate is larger, the restriction on the daemon process is higher, and the resource utilization rate is smaller, the daemon process is restricted. The degree is correspondingly smaller.
举例来说,以资源为内存为例来说明,当当前对守护进程的限制的可占用的I/O资源的数量为m或无限制时,m可为任意合适的经验值。当电子设备当前的资源利用率为a%时,电子设备可将对该守护进程的I/O资源的数量限制为n,当电子设备当前的资源利用率为b%时,电子设备可将对该守护进程的I/O资源的数量限制为k。其中,b和k均小于m,且当a小于b时,n大于k。For example, taking a resource as an example of memory, m may be any suitable empirical value when the number of available I/O resources currently limited to the daemon is m or unlimited. When the current resource utilization rate of the electronic device is a%, the electronic device may limit the number of I/O resources of the daemon to n, and when the current resource utilization rate of the electronic device is b%, the electronic device may The number of I/O resources for this daemon is limited to k. Wherein b and k are both smaller than m, and when a is smaller than b, n is greater than k.
在一个实施例中,电子设备可根据本地的资源利用率来降低守护进程的优先级,通过不同优先级所对应的资源限制程度,对该守护进程进行资源限制。其中,资源利用率越低,则对守护进程的优先级的下降幅度越小,资源利用率越高,则对守护进程的优先级的下降幅度越大。In an embodiment, the electronic device may reduce the priority of the daemon according to the local resource utilization, and limit the resource to the daemon by the degree of resource limitation corresponding to the different priorities. The lower the resource utilization rate, the smaller the priority of the daemon process, and the higher the resource utilization rate, the greater the decrease in the priority of the daemon process.
电子设备通过按照本地的资源利用率计算出对守护进程的限制程度,并根据该限制程度来对守护进程进行限制,从而可使得在本地的资源利用率较大的时候,对守护进程的限制程度更大,在本地资源的利用率较低时候,电子设备对守护进程的限制程度相对较小,使得对守护进程的限制程度与本地的资源利用率相平衡,在对前台应用的处理效率影响不大情况下,电子设备不对守护进程进行过多的限制,也避免守护进程的处理效率过于低下。The electronic device calculates the degree of restriction on the daemon process according to the local resource utilization rate, and limits the daemon process according to the degree of the restriction, so that the degree of limitation on the daemon process when the local resource utilization is large is large. Larger, when the utilization of local resources is low, the electronic device has a relatively small restriction on the daemon process, so that the degree of restriction on the daemon is balanced with the local resource utilization, and the processing efficiency of the foreground application is not affected. In large cases, the electronic device does not impose too many restrictions on the daemon process, and also avoids the processing efficiency of the daemon process is too low.
在一个实施例中,在对守护进程进行资源限制之前,还包括:检测守护进程是否被前台进程依赖;当守护进程被前台进程依赖时,将守护进程的优先级调整至与前台进程相匹配;当守护进程未被前台进程依赖时,执行对守护进程进行资源限制。In an embodiment, before the resource restriction on the daemon, the method further includes: detecting whether the daemon is dependent on the foreground process; and when the daemon is dependent on the foreground process, adjusting the priority of the daemon to match the foreground process; When the daemon is not dependent on the foreground process, the resource limit is enforced on the daemon.
在一个实施例中,电子设备对该守护进程进行依赖检测的操作,可在上述操作306之前的任意过程之中进行检测,比如,可首先进行依赖关系的检测,当不存在依赖关系时,则进行关键字的检测。当不存在依赖关系,且包含上述的关键字时,则执行守护进程进行资源限制。In an embodiment, the electronic device performs the dependency detection operation on the daemon, and may perform detection in any process before the foregoing operation 306. For example, the dependency relationship may be detected first, when there is no dependency relationship, Perform keyword detection. When there is no dependency and contains the above keywords, the daemon is executed to perform resource limitation.
依赖表示一个进程需要利用于另一个或多个进程的数据才能顺利实现对该一个进程的执行的关系。存在依赖关系的两个进程,分别为被依赖的进程和依赖的进程,电子设备将检测出的将被前台进程依赖的后台运行的守护进程判定为被前台进程依赖的后台进程。电子设备可对检测出的被前台进程所依赖的后台进程设置对应的被依赖标记,并从后台进程池中获取带有被依赖标记的后台进程,将该后台进程判定为被前台进程依赖的后台进程。Dependency indicates that a process needs to utilize data from one or more processes in order to successfully implement the relationship to the execution of that process. The two processes that have dependencies are the dependent process and the dependent process, and the electronic device detects the background running daemon that will be depended by the foreground process as the background process that is depended by the foreground process. The electronic device may set a corresponding dependency flag to the detected background process that is depended by the foreground process, and obtain a background process with the dependency mark from the background process pool, and determine the background process as a background that is depended by the foreground process. process.
针对该守护进程,当被前台进程依赖时,电子设备可将将守护进程判定为被前台进程依赖的后台进程,将被前台进程依赖的守护进程的优先级调整至与前台进程的优先级相匹 配。该前台进程即为前台运行的进程。For the daemon, when dependent on the foreground process, the electronic device can determine that the daemon process is a background process that is depended by the foreground process, and the priority of the daemon process that is dependent on the foreground process is adjusted to match the priority of the foreground process. . The foreground process is the process running in the foreground.
可选地,针对查询出的被前台进程依赖的守护进程,电子设备可对其优先级进行调整,使得调整后的优先级与该前台进程的优先级相匹配。电子设备可设置不同的被前台进程依赖的守护进程的优先级与前台优先级的匹配关系。根据该匹配关系,电子设备可以获取对应的适用于被前台进程依赖的守护进程的优先级,并将被前台进程依赖的守护进程的优先级调整至该优先级,降低对被前台进程依赖的守护进程的资源限制程度,使得对被前台进程依赖的守护进程所能使用的资源的限制程度与前台进程的限制程度相匹配。Optionally, for the queried daemon that is queried by the foreground process, the electronic device may adjust its priority so that the adjusted priority matches the priority of the foreground process. The electronic device can set different matching priorities of the daemon processes that are dependent on the foreground process and the foreground priority. According to the matching relationship, the electronic device can obtain a corresponding priority for the daemon process that is dependent on the foreground process, and adjust the priority of the daemon process that is dependent on the foreground process to the priority, and reduce the guard against the foreground process. The degree of resource throttling of a process matches the extent to which resources that can be used by daemons that are dependent on the foreground process match the limits of the foreground process.
在一个实施例中,与该前台进程的优先级相匹配的优先级,可为与该前台进程的优先级相同的优先级。即电子设备可将该被前台进程依赖的守护进程的优先级调整至与该前台进程的优先级相同的优先级,使得对被前台进程依赖的守护进程所能使用的资源的限制程度与前台进程的限制程度相同。In one embodiment, the priority that matches the priority of the foreground process may be the same priority as the foreground process. That is, the electronic device can adjust the priority of the daemon process that is depended by the foreground process to the same priority as the foreground process, so that the degree of limitation on the resources that can be used by the daemon process that is dependent on the foreground process is related to the foreground process. The limits are the same.
电子设备通过对守护进程进行依赖关系检测,将被前台进程所依赖的守护进程的优先级调整至与前台进程相配的优先级。由于通常前台进程的优先级最高,对应可使用的资源的限制程度最低,而后台进程的优先级较低,以防止后台进程占用过多的资源,对前台应用造成影响。然而后台进程中存在着被前台进程所依赖的情况,被依赖的后台进程执行效率时,也会对前台进程造成影响。本申请通过调整被依赖的守护进程的优先级调整至与前台优先级相匹配的优先级,从而可降低被依赖的守护进程所能使用的资源的限制程度,从而提高了被依赖的守护进程的处理效率。由于该被依赖的守护进程的处理效率提高了,从而也提高了依赖于该被依赖的守护进程的前台进程的处理效率。By detecting the dependency of the daemon, the electronic device adjusts the priority of the daemon that the foreground process depends on to the priority of the foreground process. Because the foreground process has the highest priority, the limit of the available resources is the lowest, and the background process has the lower priority to prevent the background process from occupying too many resources and affecting the foreground application. However, in the background process, there is a situation that is depended on by the foreground process. When the dependent background process is executed efficiently, it also affects the foreground process. The application adjusts the priority of the dependent daemon to the priority matching the foreground priority, thereby reducing the limit of the resources that the dependent daemon can use, thereby improving the dependent daemon. Processing efficiency. Since the processing efficiency of the dependent daemon is improved, the processing efficiency of the foreground process depending on the dependent daemon is also improved.
在一个实施例中,如图4所示,提供了另一种进程处理方法,该方法包括:In one embodiment, as shown in FIG. 4, another process processing method is provided, the method comprising:
操作402,获取处于后台运行的守护进程的进程信息。Operation 402: Obtain process information of a daemon running in the background.
可选地,进程信息包括上述的进程名称和UID。电子设备可对本地运行的所有进程进行扫描,以获取处于后台运行的守护进程的进程名称和UID。可选地,电子设备可同时获取多个守护进程的进程名称和UID,还可按照预设的顺序,在完成对其中一轮的守护进程的检测之后,再获取下一轮的守护进程的进程信息并进行检测,其中,每一轮中包含的进程的数量可为一个或多个且不一定行相同。Optionally, the process information includes the process name and UID described above. The electronic device scans all processes running locally to get the process name and UID of the daemon running in the background. Optionally, the electronic device can acquire the process name and the UID of the multiple daemons at the same time, and obtain the process of the next round of the daemon process after completing the detection of one of the daemons in a preset order. Information is detected and detected, wherein the number of processes included in each round may be one or more and may not be the same.
在一个实施例中,电子设备可通过图2中的冻结管理应用210,通过Binder接口向资源优先级和限制管理模块222发送对守护进程的检测调整指令,该资源优先级和限制管理模块222通过接收到的检测指令获取守护进程的进程信息。In one embodiment, the electronic device may send a detection adjustment instruction to the daemon process to the resource priority and restriction management module 222 through the Binder interface through the freeze management application 210 in FIG. 2, and the resource priority and restriction management module 222 passes The received detection instruction acquires the process information of the daemon.
操作404,检测进程信息中的进程名称是否包含第一关键字;检测进程信息中的用户身份标识UID是否包含第二关键字。 Operation 404, detecting whether the process name in the process information includes the first keyword; and detecting whether the user identity UID in the process information includes the second keyword.
在一个实施例中,第一关键字可为“dex2oat”。第二关键字可为“2999”的关键字,电子设备可检测进程名称中是否包含“dex2oat”,以及UID的前是否为以“2999”开头的UID,其中,“2999”的后面还可包含连续的多个9,比如可为“299999”、“2999999”或“29999999”等。In one embodiment, the first keyword may be "dex2oat." The second keyword may be a keyword of "2999", and the electronic device may detect whether the process name includes "dex2oat" and whether the UID is preceded by a UID starting with "2999", wherein "2999" may be included after A plurality of consecutive 9, such as "299999", "2999999" or "29999999".
操作406,当包含第一关键字和第二关键字,且前台应用为游戏类应用时,对守护进程进行资源限制,对守护进程所占用的CPU资源和I/O资源进行限制。 Operation 406, when the first keyword and the second keyword are included, and the foreground application is a game application, the resource limitation is performed on the daemon, and the CPU resources and I/O resources occupied by the daemon are restricted.
在一个实施例中,当守护进程的第一关键字中包含“dex2oat”,且UID的前4位为“2999”,或者包含更多连续的“9”时,电子设备可以判定该守护进程为应用安装进程,并对识别出的应用安装进程进行标记。同时,电子设备可检测前台应用是否为游戏应用,当为游戏应用时,则对该守护进程的可占用的CPU资源和I/O资源进行限制。比如,电子设备的CPU为8核或者6核的CPU,则可限制该守护进程可占用的CPU仅为1核,以提供更多的CPU资源供前台运行的游戏应用所使用。当前台应用对I/O接口的占用为30个或20个时,电子设备可以限制其只能占用3个I/O接口,以提供更多的I/O资源供前台运行的游戏应用所使 用。In an embodiment, when the first keyword of the daemon includes "dex2oat", and the first 4 digits of the UID are "2999", or contains more consecutive "9", the electronic device may determine that the daemon is Apply the installation process and mark the identified application installation process. At the same time, the electronic device can detect whether the foreground application is a game application, and when it is a game application, limit the occupied CPU resources and I/O resources of the daemon. For example, if the CPU of the electronic device is an 8-core or a 6-core CPU, the CPU that can be occupied by the daemon can be limited to only one core, so as to provide more CPU resources for the game application running in the foreground. When the current application uses 30 or 20 I/O interfaces, the electronic device can limit it to occupy only 3 I/O interfaces to provide more I/O resources for use by game applications running in the foreground. .
在一个实施例中,电子设备可通过Binder接口向资源优先级和限制管理模块222发送对检测出的守护进程的资源限制指令。可选地,该资源限制指令可为对守护进程的优先级调整指令。资源优先级和限制管理模块222接收到该优先级调整指令后,降低相应的守护进程的优先级,提高对其资源限制,防止前台应用出现卡顿。In one embodiment, the electronic device may send a resource limit instruction to the detected daemon to the resource priority and limit management module 222 via the Binder interface. Optionally, the resource limit instruction may be a priority adjustment instruction to the daemon. After receiving the priority adjustment instruction, the resource priority and limit management module 222 lowers the priority of the corresponding daemon process, increases the resource limit thereof, and prevents the foreground application from being stuck.
在一个实施例中,在对守护进程的资源进行限制之前,还包括:检测守护进程是否被前台进程依赖,当守护进程未被前台进程依赖时,电子设备可以对守护进程所占用的CPU资源和I/O资源进行限制。In an embodiment, before limiting the resources of the daemon, the method further includes: detecting whether the daemon is dependent on the foreground process, and when the daemon is not dependent on the foreground process, the electronic device may use CPU resources occupied by the daemon. I/O resources are restricted.
在一个实施例中,当守护进程与前台进程之间存在socket通信、binder通信、内存共享或锁等待时,电子设备可以判定后台进程与前台进程之间存在通信机制。In one embodiment, when there is socket communication, binder communication, memory sharing, or lock waiting between the daemon and the foreground process, the electronic device can determine that there is a communication mechanism between the background process and the foreground process.
可通过以下任意一种或几种方式检测是否存在与前台进程具有通信机制的后台进程:You can detect whether there is a background process that has communication mechanism with the foreground process by any one or several of the following methods:
(1)检测是否存在与前台进程具有socket和binder通信中的至少一种的后台进程;(1) detecting whether there is a background process having at least one of socket and binder communication with the foreground process;
(2)检测是否存在与前台进程之间进行内存共享的后台进程;(2) detecting whether there is a background process for memory sharing with the foreground process;
(3)检测是否存在前台进程等待在锁资源上的后台进程。(3) Check if there is a background process waiting for the foreground process to wait on the lock resource.
电子设备可在Binder驱动中设置对前台进程和后台进程之间是否存在Binder通信的检测机制,并调用在Binder驱动中设置的检测机制,以检测出与前台进程存在Binder通信的后台进程,将检测出的后台进程判定为被前台进程依赖的后台进程。The electronic device can set a detection mechanism for the Binder communication between the foreground process and the background process in the Binder driver, and call the detection mechanism set in the Binder driver to detect the background process in which the Binder communication exists with the foreground process, and the detection will be detected. The background process is determined to be a background process that is dependent on the foreground process.
在一个实施例中,电子设备可检测各个锁资源,锁资源包括线程锁,文件句柄,信号等。针对每个锁资源,可检测是否发生锁等待,即锁资源等待。当检测到产生锁等待时,可进一步检测该发生等待的行为是否发生在前台进程上。若是,则遍历等待在该锁资源上面的所有后台进程,将检测到的等待在该锁资源上的后台进程均判定为被前台进程依赖的后台进程。In one embodiment, the electronic device can detect individual lock resources, including thread locks, file handles, signals, and the like. For each lock resource, it can be detected whether a lock wait occurs, that is, the lock resource waits. When it is detected that a lock wait is generated, it may be further detected whether the behavior of the occurrence of the wait occurs on the foreground process. If so, all the background processes waiting for the lock resource are traversed, and the detected background processes waiting on the lock resource are all determined to be background processes that are depended by the foreground process.
在一个实施例中,电子设备可在操作系统的内核空间中设置锁资源监控模块和优先级调整模块,将锁资源监控模块内嵌到内核原生的等待接口当中。通过该锁资源监控模块,检测线程锁,文件句柄,信号等锁各种锁资源,是否发生等待,发生等待的行为是否是发生在前台进程上面,如果是发生在前台任务上面,则将检测到的消息发送至优先级调整模块。电子设备通过该优先级调整遍历等待在该锁资源上面的所有后台线程,将这些后台进程判定为被前台进程依赖的后台进程。并通过该优先级调整模块将相应的守护进程的优先级调整至相匹配的优先级。In one embodiment, the electronic device may set a lock resource monitoring module and a priority adjustment module in a kernel space of the operating system, and embed the lock resource monitoring module into the kernel's native waiting interface. Through the lock resource monitoring module, detecting thread locks, file handles, signals, etc. lock various lock resources, whether a wait occurs, whether the waiting behavior occurs on the foreground process, and if it occurs on the foreground task, it will detect The message is sent to the priority adjustment module. The electronic device traverses all the background threads waiting for the lock resource by the priority adjustment, and determines these background processes as the background processes that are depended by the foreground process. And the priority adjustment module adjusts the priority of the corresponding daemon to the matching priority.
在一个实施例中,在操作304之前,还包括:当后台进程与前台进程之间存在同步机制时,判定具有同步机制的守护进程为被前台进程依赖的后台进程。In an embodiment, before the operation 304, the method further includes: when there is a synchronization mechanism between the background process and the foreground process, determining that the daemon having the synchronization mechanism is a background process that is dependent on the foreground process.
电子设备还可通过调用futex系统调用检测后台进程集合中,是否存在与前台进程具有同步机制的后台进程,将具有同步机制的后台进程判定为被前台进程依赖的后台进程。The electronic device can also detect the background process in the background process set by calling the futex system call, whether there is a background process having a synchronization mechanism with the foreground process, and determine the background process with the synchronization mechanism as the background process that is depended by the foreground process.
并发程序设计中,各进程对公共变量的访问必须加以制约,这种制约称为同步。在操作系统中,用户态(user mode)的同步机制可通过调用futex系统调用实现。其中,用户态指非特权状态。同步机制包括信号量、互斥锁等。当通过futex系统调用检测到与前台进程存在任意一种同步机制的后台进程时,可将检测到的后台进程判定为被前台进程依赖的后台进程。In concurrent programming, access to public variables must be restricted by each process. This constraint is called synchronization. In the operating system, the user mode synchronization mechanism can be implemented by calling the futex system call.
