Detailed Description
The following description will explain the process management method in the mobile application compatible running environment according to the present invention, which implements unified scheduling and control of the native system Web process and the android process on the resource usage of CPU, memory, etc. in the kylin mobile operating system, so as to improve the system performance in the heterogeneous mobile application compatible running environment.
Referring to fig. 1, the method for managing processes in a mobile application compatible execution environment in the embodiment at least includes the following steps:
step 1: packaging a system WEB process and an android compatible process in a mobile application compatible running environment, comprehensively studying and judging by adopting multi-dimensional characteristic information of the packaged processes to obtain priorities, distributing available resources of the processes according to the priorities of the processes, including distributing CPU (central processing unit) and memory resources, adjusting boost acceleration performance, reducing potential risks caused by uncontrolled resource competition, improving overall performance of the system, and providing evaluation basis for memory recovery;
step 2: and dynamically monitoring the memory risk by using a memory management mechanism based on a shared kernel, triggering a garbage recovery and low memory searching and killing process according to a priority real-time distribution result of the process and the memory tension degree, and keeping the important process alive.
Referring to fig. 2, in the kylin mobile operating system, specifically in step 1, the system packages a Web process and an android compatible process as process template objects and stores the process template objects by setting a Process Manager (PM), and determines and decides a standard priority according to process multidimensional characteristic data. In the kylin mobile operating system, the operation of a management process runs through the service cycle of equipment, other processes are derived, and a process manager is embedded into the management process to run in order to guarantee the continuity of priority updating and facilitate process management. When the management process of the system derives the process, the system native process is packaged into a Process Template Object (PTO), the process characteristics are cut, and partial characteristics are migrated into the process template object, wherein the migrated characteristics include but are not limited to held resource locks, application types and running states. And simultaneously, the process manager is designed into a binder server-side form, after the android process is established, a binder service interface of the process manager is called to package and map the android process into a process template object, and the process template object is stored in the process manager in an array form. And the process manager monitors the life cycle event of the process and updates the process template object array according to the creation and destruction conditions of the process. In the step 1, unified evaluation of the process behaviors is facilitated through a normalization processing mode of heterogeneous system WEB process and android compatible process packaging.
After the WEB process and the android compatible process are packaged, comprehensive research and judgment are carried out on the multidimensional characteristic information of the packaged process to obtain the priority, and the method specifically comprises the following steps:
1-1: obtaining an initial priority according to the application type of the process;
1-2: the method comprises the steps that a standard priority is obtained according to a process active notification fusion initial priority, and the process active notification can reflect the running state of a process;
1-3: adjusting the standard priority according to whether the process holds a resource lock or uses a perceptible resource;
1-4: the priorities of the foreground process and the previous affected process are updated.
The embodiment provides a judging strategy: firstly, considering the application type, the process priority can be divided into a management process, a user customized keep-alive process, an input method process, a WEB application process, an android application process and a pre-allocation process from high to low, and an initial priority is given according to the application type.
In the kylin mobile operating system, a management process has the highest access resource authority, is a root process derived from the original system process, and can manage all other processes only by ensuring that the management process has extremely high priority. The user customizes the keep-alive process, the process which is set for the user and is not killed by mistake as far as possible when the resources are in tension is determined by whether the special field 'persistence' is identified when the application is written. The foreground input method has higher priority than the common foreground because the interaction experience of the user is determined to a great extent. The foreground process is the topmost application process visible to the user, can be an original operating system application process, and can also be an android compatible process, and whether the process is consistent with the visibility of the process at the topmost end or not is judged. When the ACTIVITY of the client process is visible and the bindService () method is called, the flags carry a BIND _ ADJUST _ WITH _ ACTIVITY parameter, and then the current android service process belongs to the foreground process. The background is an application process which does not occupy the most front end window or an inactive service process. The background perceptible process is a background process which is using video and audio services. Because the kylin mobile operating system ensures the speed of opening the application for the first time by the user, the pre-installed template process allocates resources, the priority of the process can not be high, and the process is switched to the foreground priority after the process is really operated.
According to whether the active notification is located in the foreground or not, namely whether the application can be displayed or not, a standard priority is obtained according to the process active notification and the fusion initial priority, wherein both WEB applications and android applications are possible to be located in the foreground or the background, but the management process, the user customized keep-alive process and the input method have higher priority than the foreground, the pre-distribution has lower priority than the background and is not influenced by the foreground and the background, when the behaviors of the WEB process and the android compatible process are changed or the system behavior is changed, a process manager is called to update the process active notification, the active notification message is sent to a corresponding process template object, the standard priority is determined according to the application type in the process characteristics, and therefore all the processes are brought into the management of the process manager. The method comprises the steps that process behaviors include but are not limited to process creation, starting, backing to a background, destroying, resource lock application, resource lock release and the like, system behaviors include but are not limited to screen lightening, screen blanking, screen locking, unlocking, memory cleaning and the like, when a process running state changes, a system native process sends an active notification message to a corresponding process template object through an IPDL communication mode and an android compatible process through a binder interface, and a process manager obtains a standard priority according to characteristic data stored in the process template object mapped by the system native process and the android compatible process.
And finally, fine-tuning the standard priority according to the condition that each resource lock is held in the process and whether the sensible resource condition is used. Including but not limited to audio, video playback, recording video. Such as WEB applications or android applications, enter the background but have the property of playing audio, so that the priority level is changed from the background to the background. And the priority evaluation is carried out on the compatible system process through the multidimensional information, so that the resource allocation is matched with the user operation with finer granularity, and the use experience is better.
Particularly, when the application process is set to the forefront to become a foreground process, if the rendering of the Web application or the android application is finished, a process active notification is issued, the process manager indexes a process template object, the priority of the process and the previous affected process is calculated, and the process manager calls a CGROUP grouping module (CGROUPManager, CM) to realize the updating of the process and the previous affected process. In this embodiment, a user opens an application on an original system desktop, the application has a foreground priority, and the original system desktop is a background priority; when the application exits, the application is in background priority, and the original system desktop is in foreground priority.
In the embodiment, an initial priority is obtained according to the application type of a process; however, the running state of the feedback application is informed through the process activity, the standard priority is obtained by fusing the initial priority, and the priority evaluation is carried out on the heterogeneous process through fusing the multidimensional information according to whether the process holds the resource lock and whether the standard priority is adjusted by using the sensible resource, so that the resource allocation is matched with the user operation in a finer granularity, and the use experience is better.
In the present invention, the allocation of available resources of a process according to its priority is specifically implemented as follows:
establishing a priority mapping table, mapping the standard priority adjusted by the process to a CGROUP control node in a CGROUP grouping module of the system through the priority mapping table, and distributing available resources of the process by the CGROUP control node according to the written standard priority, wherein the available resources comprise CPU resources, memory resources and boost speed-up performance.
In the embodiment, a CGROUP grouping module is designed at a hardware abstraction layer of the kylin mobile operating system, a priority mapping table is established, the process priority is determined and then mapped into an actual CGROUP control node through the priority mapping table, the operation between different levels is isolated, and the input is provided for a memory management module. Because the process priority operation is calculated and set in the management process, the CGROUP grouping module does not need to design a sandbox interface, and only needs to design an impl interface. And the process manager decides the standard priority of the process, calls a CGROUP grouping module to map the priority into the attribute value of the CGROUP grouping through a priority mapping table, and realizes the dynamic writing of the priority into the CGROUP control node. The higher the process priority decided by the process manager is, the more the number of cores which can run corresponding to the CGROUP is, the larger the share of the CPU is occupied, and the larger the boost value is, the more obvious the boost performance is improved. If the fg directory under the schedule root directory of the foreground priority group corresponding to CGROUP, the schedule.
In this embodiment, a priority mapping table, which is a mapping table for dynamically adjusting the correspondence between the process priority and the CGROUP grouping module and the key attribute values thereof in the kylin mobile operating system, is provided, so as to dynamically adjust the CPU proportion used by the process, the process speed increase size, the number of CPU cores occupied by the process, and the like according to the process priority obtained by the process manager, and table 1 provides a reference scheme for the priority mapping table, which can be specifically changed according to requirements.
The CPU in the table represents the name of a CPU group in CGROUP corresponding to each process priority, fg-default, fg-persistence, fg-keyboard, top, bg-persistence and bg-prealloc groups are distributed in the method, the CPU (CPU _ shares) represents the proportion of CPU time occupied by each group, and the larger the value is, the more the proportion of CPU time is occupied, the more the operation chance is. The schedule represents the name of a schedule group in CGROUP corresponding to the priority of each process, fg-default, fg-persistence, fg-keyboard, top, bg-persistence and bg-prealloc groups are allocated in the patent, schedule (schedule.
