Description

进程控制方法及相关设备
本发明要求2016年5月31日递交的发明名称为“一种进程控制方法及终端设备”的申请号201610380762.8的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明涉及电子技术领域，尤其涉及一种进程控制方法及相关设备。
背景技术
在移动操作系统中，内核空间主要包含各种移动操作系统核心功能(比如进程调度，内存管理，中断响应，用户系统调用等)。进程调度模块主要是让各个进程在不同的状态中来回切换。内核的进程状态通常包含以下几种：1、正在执行状态；2、可执行状态；3、可中断的睡眠状态；4、不可中断的睡眠状态；5、暂停状态；6、退出状态。其中，正在执行状态表示进程或线程已经获取CPU正在执行过程中；可执行状态表示进程可以运行但没有获取CPU资源，不可中断的睡眠状态表示进程处于睡眠状态，但是此刻进程是不可中断的；可中断的睡眠状态表示进程处于睡眠状态但是该进程是可终端的；暂停状态表示进程暂停下来不可运行；退出状态表示进程已经开始退出。
不可中断的睡眠状态存在的意义就在于，内核的某些处理流程是不能被打断的。如果响应异步信号，程序的执行流程中就会被插入一段用于处理异步信号的流程(这个插入的流程可能只存在于内核态，也可能延伸到用户态)，于是原有的流程就被中断了。在进程对某些硬件进行操作时(比如进程调用读写系统调用对某个设备文件进行读写操作，读写系统调用最终执行到对应设备驱动的代码，并与对应的物理设备进行交互)，可能需要使用不可中断的睡眠状态的进程进行保护，以避免进程与设备交互的过程被打断，造成设备陷入不可控的状态。然而不可中断睡眠状态的持续时间较长时，会给操作系统带来响应延迟，进而影响操作系统的稳定性。

以下分别进行详细说明。

以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、终端设备，又称之为用户设备(User Equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、 车载设备等。常见的终端例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。

请参见图1，图1为本发明实施例提供的一种进程控制方法的流程示意图，包括以下步骤：
S101、若检测到内核空间中的N个进程处于不可中断睡眠状态的时间超过预设时长，则终端设备检测所述N个进程在所述预设时长内是否存在被查杀记录，所述N为大于或等于1的整数。
S102、若所述N个进程在所述预设时长内存在被查杀记录，则所述终端设备更改所述N个进程的进程状态，以及控制操作系统根据更改后的所述N个进程的进程状态运行所述N个进程。
举例来说，终端设备周期性的检测内核空间中的所有进程的进程状态，通常不可中断睡眠状态的持续时间很短，如果内核空间中N个进程的处于不可中断睡眠状态的时间超过预设时长时，该种情况下，会给操作系统带来响应延迟，进而影响操作系统的稳定性，因此，在该种情况下，终端设备会检测这N个进程在该预设时长内是否有被看门狗程序查杀，通常进程长时间持续在某个进程状态且不可退出时会引起操作系统的看门狗程序运行，看门狗程序会结束该进程，而不可中断，指的并不是CPU不响应外部硬件的中断，而是指进程不响应异步信号，其中的所有异步信号也包含查杀信号，也就是说看门狗程序也无法及时结束进程状态为不可中断睡眠状态的进程的运行，若终端设备检测到这N个进程在该预设时长内存在被看门狗程序查杀记录，终端设备直接更改这N个进程的进程状态，最后终端设备控制操作系统根据更改后的这N个进程的进程状态运行这N个进程，可避免操作系统因某些进程长时间处于不可中断睡眠状态的问题，从而可提高操作系统的稳定性。
其中，更改这N个进程的进程状态可以是：将这N个进程的进程状态从 不可中断睡眠状态更改为退出状态或是更改为暂停状态等等，本发明不作限定。
可选的，在以上步骤S102更改所述N个进程的进程状态之前，图1所示的方法还包括：
终端设备为所述N个进程分配N个存储空间，所述N个存储空间与所述N个进程一一对应；所述终端设备将所述N个进程的统计信息对应存储于所述N个存储空间中。
举例来说，由于不可中断的睡眠状态存在的意义就在于，内核的某些处理流程是不能被打断的。如果这些处理流程被打断可能会导致数据丢失等问题。因此在更改这N个进程的进程状态之前，先保存这N个进程的临时数据，以确保更改后下次启动能找到这些进程。由于不同的进程所占用的资源大小不同，不同的进程需要存储的临时数据大小也不尽相同，因此终端设备可根据N个进程所占用的资源大小为这N个进程分配N个存储空间，然后将这N个进程的临时数据(即统计信息)对应保存到这N个存储空间中。
可选的，在以上步骤S102更改所述N个进程的进程状态之前，图1所示的方法还包括：
终端设备将所述N个进程进行分组，以得到K组进程集，每组进程集包括的进程的类型是相同的；所述终端设备为所述K组进程集分配K个存储空间，所述K个存储空间与所述K组进程集一一对应；所述终端设备将所述K组进程集的统计信息对应存储于所述K个存储空间中。
举例来说，由于不可中断的睡眠状态存在的意义就在于，内核的某些处理流程是不能被打断的。如果这些处理流程被打断可能会导致数据丢失等问题。因此在更改这N个进程的进程状态之前，先保存这N个进程的临时数据，以确保更改后下次启动能找到这些进程。由于不同的进程可能类型是相同的，比如都是系统进程，或者都是第三方应用进程等等，为了方便管理，终端设备可先将这N个进程进行分组，得到K组进程集(比如N＝4，4个进程有：第一进程、第二进程、第三进程和第四进程，第一进程和第二进程类型相同，第三进程和第四进程类型相同，那么分组后得到2组进程集，第一组进程集包括第一进程和第二进程，第二组进程集包括第三进程和第四进程)，然后为K组进 程集分配K个存储空间，然后再将这K组进程集的临时数据(即统计信息)对应保存到这K个存储空间中。
可选的，上述统计信息包括进程标识符(操作系统每运行一个进程都会创建一个进程ID，这个进程ID就是进程标识符，进程标识符用于区别不同的进程)、进程更改进程状态之前所处的进程状态(比如进程A更改进程状态之前的进程状态为不可中断睡眠状态，此时统计信息里此处为不可终端睡眠状态)、进程处于不可中断睡眠状态的时间(比如进程A处于不可中断睡眠状态的时间为2s，此时统计信息里此处为2s)以及进程的数据信息状态(比如进程A加载完成或传输数据完成比例为50％，此时统计信息里此处为加载完成或传输完成比例为50％)中的至少一种。当然，上述统计信息不仅限于这些信息，本发明不作限定。
可选的，若所述N个进程中存在至少一个进程为系统进程，以上步骤S102的具体实施方式为：
所述至少一个系统进程中存在影响所述操作系统正常运作的系统进程，则终端设备将内核空间中所有的进程的进程状态更改为退出状态，控制所述操作系统退出所述内核空间中所有的进程以及重启所述操作系统；若所述至少一个系统进程中不存在影响所述操作系统正常运作的系统进程，则终端设备将所述N个进程中至少一个进程的进程状态更改为退出状态，以及控制所述操作系统退出所述至少一个进程。
举例来说，操作系统运行的进程可以是系统进程(比如电源管理进程、活动管理器进程、电话进程等)也可以是应用进程(比如QQ、微信、微博等)等。假设上述N个进程中存在至少一个系统进程，且这至少一个系统进程中存在影响操作系统正常运作的系统进程，比如，电源管理进程(主要用于控制操作系统与电源相关部分，如果该进程长时间处于不可中断睡眠状态，会导致终端设备屏幕可能无法变暗或变亮，进而影响操作系统正常运作)，该种情况下，终端设备将内核空间中所有的进程直接退出，然后重启操作系统，以恢复终端设备的操作系统的正常运行。假设上述N个进程中存在至少一个系统进程，且这至少一个系统进程中不存在影响操作系统正常运作的系统进程，该种情况下，终端设备将这N个进程中的至少一个进程退出，以缓解操作系统的 稳定性，其中，至少一个进程包含N个进程，也就是说，终端设备可将这N个进程全部退出。
可选的，以上步骤S102的具体实施方式为：
若所述N个进程的占用资源位置相同，则终端设备将所述N个进程中的N-1个进程的进程状态更改为暂停状态，以及控制所述操作系统暂停所述N-1个进程。
举例来说，通常情况一个资源只能被一个进程占用，假设N个进程抢占一个资源时，可能会出现这些进程都运行不了的情况，进而导致这些进程长时间处于不可中断睡眠状态。该种情况下，终端设备可选择这N个进程中的其中一个进程先运行，其他N-1个进行暂停运行，其具体实现方式如上，这样可保证这N个进程在无需退出的情况下，正常运行。
可选的，若更改所述N个进程的进程状态为退出状态，以上步骤S102之后，图1所示的方法还包括：
若所述内核空间的资源被占用的比例小于或等于第一阈值，终端设备根据所述N个进程的统计信息启动所述N个进程；若所述内核空间的资源被占用的比例大于所述第一阈值且小于第二阈值，所述终端设备从所述N个进程中选取出W个进程，以及根据所述W个进程的统计信息启动所述W个进程，所述W个进程的优先级大于或等于所述N个进程中除了所述W个进程之外的进程的优先级，所述W为大于或等于1的整数。
举例来说，假设在上述N个进程长时间处于不可中断睡眠状态后，终端设备直接将这N个进程的进程状态更改为退出状态，然后控制操作系统退出这N个进程的时，后续用户还想恢复这N个进程，通常的做法是，用户手动启动这个N个进程，本方案中，终端设备可在内核空间的资源被占用的比例小于或等于第一阈值的情况下，可直接启动这N个进程，进而可提高用户体验。其中，第一阈值例如可以等于20％、25％、30％、32％或是其他值。另外，终端设备可在内核空间的资源被占用的比例大于第一阈值且小于第二阈值，可以只启动这N个进程中优先级较大的W个即可，比如N＝4，W＝2，N个进程的优先级关系有：进程1＞进程3＞进程4＞进程2，则启动的W个进程为进程1和进程3。其中，启动进程的方法可以是终端设备根据这些进程上一次关 闭时存储的统计信息来启动这些进程，比如，进程A上一次关闭时存储的统计信息有进程标识符为ID1，进程更改进程状态之前所处的进程状态为不可终端睡眠状态，进程的数据信息状态为传输数据完成比例为50％，则操作系统根据进程标识符启动进程A、进程A的进程状态为不可终端睡眠状态，且进程A是从数据传输50％处开始的。
本发明实施例还提供了另一更为详细的方法流程，如图2所示，包括：
S201、终端设备周期性检测内核空间中的所有进程的进程状态。若所述终端设备检测到所述内核空间中的N个进程处于不可中断睡眠状态的时间超过预设时长，则执行步骤S202，所述N为大于或等于1的整数。
S202、所述终端设备检测所述N个进程在所述预设时长内是否存在被查杀记录。
若是，则执行步骤S203。
若否，则不作任何操作。
S203、所述终端设备为所述N个进程分配N个存储空间，所述N个存储空间与所述N个进程一一对应。
S204、所述终端设备将所述N个进程的统计信息对应存储于所述N个存储空间中。
S205、所述终端设备更改所述N个进程的进程状态，以及控制操作系统根据更改后的所述N个进程的进程状态运行所述N个进程。
S206、若更改所述N个进程的进程状态为退出状态，所述终端设备确定所述内核空间的资源被占用的比例是否小于或等于第一阈值。
若是，则执行步骤S207。
若否，则执行步骤S208。
S207、所述终端设备根据所述N个进程的统计信息启动所述N个进程。
S208、所述终端设备确定所述内核空间的资源被占用的比例是否大于所述第一阈值且小于第二阈值。
若是，则执行步骤S209。
若否，则不作任何操作。
S209、所述终端设备从所述N个进程中选取出W个进程，以及根据所述W个进程的统计信息启动所述W个进程，所述W个进程的优先级大于或等于所述N个进程中除了所述W个进程之外的进程的优先级，所述W为大于或等于1的整数。
需要说明的是，图2所示的各个步骤的具体实现方式可参见上述方法的具体实现方式，在此不再叙述。

RF电路510可用于收发信息或通话过程中，信号的接收和发送，特别地，将基站的下行信息接收后，给处理器580处理；另外，将设计上行的数据发送给基站。通常，RF电路510包括但不限于天线、至少一个放大器、收发信机、耦合器、低噪声放大器(Low Noise Amplifier，LNA)、双工器等。此外，RF电路510还可以通过无线通信与网络和其他设备通信。上述无线通信可以使用任一通信标准或协议，包括但不限于全球移动通讯系统(Global System of Mobile communication，GSM)、通用分组无线服务(General Packet Radio Service，GPRS)、码分多址(Code Division Multiple Access，CDMA)、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)、长期演进(Long Term Evolution，LTE)、电子邮件、短消息服务(Short Messaging Service，SMS)等。
存储器520可用于存储软件程序以及模块，处理器580通过运行存储在存储器520的软件程序以及模块，从而执行手机的各种功能应用以及数据处理。存储器520可主要包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序(比如进程检测功能、进程状态更改功能，存储空间分配功能等)等；存储数据区可存储根据手机的使用所创建的数据(比如进程的统计信息、进程被查杀记录等)等。此外，存储器520可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
输入单元530可用于接收输入的数字或字符信息，以及产生与手机的用户 设置以及功能控制有关的键信号输入。具体地，输入单元530可包括触控面板531以及其他输入设备532。触控面板531，也称为触摸屏，可收集用户在其上或附近的触摸操作(比如用户使用手指、触笔等任何适合的物体或附件在触控面板531上或在触控面板531附近的操作)，并根据预先设定的程式驱动相应的连接装置。可选的，触控面板531可包括触摸检测装置和触摸控制器两个部分。其中，触摸检测装置检测用户的触摸方位，并检测触摸操作带来的信号，将信号传送给触摸控制器；触摸控制器从触摸检测装置上接收触摸信息，并将它转换成触点坐标，再送给处理器580，并能接收处理器580发来的命令并加以执行。此外，可以采用电阻式、电容式、红外线以及表面声波等多种类型实现触控面板531。除了触控面板531，输入单元530还可以包括其他输入设备532。具体地，其他输入设备532可以包括但不限于物理键盘、功能键(比如音量控制按键、开关按键等)、轨迹球、鼠标、操作杆等中的至少一种。
显示单元540可用于显示由用户输入的信息或提供给用户的信息以及手机的各种菜单。显示单元540可包括显示面板541，可选的，可以采用液晶显示器(Liquid Crystal Display，LCD)、有机发光二极管(Organic Light-Emitting Diode,OLED)等形式来配置显示面板541。进一步的，触控面板531可覆盖显示面板541，当触控面板531检测到在其上或附近的触摸操作后，传送给处理器580以确定触摸事件的类型，随后处理器580根据触摸事件的类型在显示面板541上提供相应的视觉输出。虽然在图5中，触控面板531与显示面板541是作为两个独立的部件来实现手机的输入和输入功能，但是在某些实施例中，可以将触控面板531与显示面板541集成而实现手机的输入和输出功能。
手机还可包括至少一种传感器550，比如光传感器、运动传感器以及其他传感器。具体地，光传感器可包括环境光传感器及接近传感器，其中，环境光传感器可根据环境光线的明暗来调节显示面板541的亮度，接近传感器可在手机移动到耳边时，关闭显示面板541和/或背光。作为运动传感器的一种，加速计传感器可检测各个方向上(一般为三轴)加速度的大小，静止时可检测出重力的大小及方向，可用于识别手机姿态的应用(比如横竖屏切换、相关游戏、磁力计姿态校准)、振动识别相关功能(比如计步器、敲击)等；至于手机还可配置的陀螺仪、气压计、湿度计、温度计、红外线传感器等其他传感器，在 此不再赘述。
音频电路560、扬声器561，传声器562可提供用户与手机之间的音频接口。音频电路560可将接收到的音频数据转换后的电信号，传输到扬声器561，由扬声器561转换为声音信号输出；另一方面，传声器562将收集的声音信号转换为电信号，由音频电路560接收后转换为音频数据，再将音频数据输出处理器580处理后，经RF电路510以发送给比如另一手机，或者将音频数据输出至存储器520以便进一步处理。
WiFi属于短距离无线传输技术，手机通过WiFi模块570可以帮助用户收发电子邮件、浏览网页和访问流式媒体等，它为用户提供了无线的宽带互联网访问。虽然图5示出了WiFi模块570，但是可以理解的是，其并不属于手机的必须构成，完全可以根据需要在不改变发明的本质的范围内而省略。
处理器580是手机的控制中心，利用各种接口和线路连接整个手机的各个部分，通过运行或执行存储在存储器520内的软件程序和/或模块，以及调用存储在存储器520内的数据，执行手机的各种功能和处理数据，从而对手机进行整体监控。可选的，处理器580可包括一个或多个处理单元；优选的，处理器580可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器580中。
手机还包括给各个部件供电的电源590(比如电池)，优选的，电源可以通过电源管理系统与处理器580逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
尽管未示出，手机还可以包括摄像头、蓝牙模块等，在此不再赘述。
