Detailed Description
The technical scheme of the application is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
The file operation Processing procedure between the electronic device and other external terminal devices uses MTP as a main transmission mode by default, and file Processing operation based on MTP can only process one file or one folder each time, so that time consumption for Processing the whole process of a plurality of files is large when a plurality of files are processed, and therefore when the file Processing task based on MTP is run, the running condition of the file Processing task is optimized according to the running condition of a Central Processing Unit (CPU) of the electronic device, and the file Processing process speed of a user can be increased.
Fig. 1 is a flowchart of a file processing method provided in an embodiment of the present application, where the file processing method may be executed by a file processing apparatus, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in a terminal device. As shown in fig. 1, the method includes:
and step 110, when a starting instruction of the MTP-based file processing task is detected, calling an MTP drive to start the CPU multi-core and improving the performance output of the CPU.
Illustratively, as shown in fig. 2, the MTP-based file processing task is a file processing task between the electronic device and an external terminal device, and includes at least one of a file copy task, a file cut task, a file paste task, a file delete task, and a file rename task. The electronic device can be a smart phone, a tablet computer or other android system running devices, and the external terminal device can be a PC or other operable devices. Two roles are involved in the execution of the MTP-based file processing task, including an Initiator (Initiator) and a Responder (Responder); the external terminal equipment is used as an initiator, the electronic equipment is used as a responder, and the initiator and the responder are matched with each other for communication so as to complete the document processing task. For example, the smart phone is connected with an external computer, and a file or a folder in the smart phone is copied to a hard disk of the computer through computer operation, or the file or the folder in the smart phone is deleted through the computer, or the file or the folder in the smart phone is renamed through the computer, and the like.
Exemplarily, when MtpServer detects a start instruction of an MTP-based file processing task, an MTP driver is called by an ioctl command, and the MTP driver performs CPU scheduling, including: starting CPU multi-core and improving the performance output of the CPU. Boosting the performance output of the CPU may include boosting the frequency of the CPU, which may be adjusting the frequency of the CPU to a maximum. The frequency of the CPU, namely the clock frequency of the CPU, namely the working frequency of the CPU during operation is adjusted to the designed highest frequency of the CPU, so that the working performance of the CPU is maximized. The MTP driver is located in the kernel, and the ioctl command is a function for managing an I/O channel of the device in the device driver, and provides a way of obtaining device information and sending control parameters to the device. The MtpServer continuously detects whether a starting instruction of a file processing task exists, performs related processing on the corresponding instruction, and calls the MTP driver through an ioctl command when the starting instruction is detected so that the MTP driver executes the scheduling of the CPU.
Optionally, the frequency of the CPU is correspondingly adjusted according to the number of tasks in the file processing task and/or the size of task data, where the number of tasks is the total number of tasks in the file processing task, and the size of task data is the sum of the sizes of data of files processed in the file processing task. The more the number of the tasks is, the higher the frequency of correspondingly improving the CPU is, the larger the size of the task data is, and the higher the frequency of correspondingly improving the CPU is. For example, a file processing task includes one file copy task and two file delete tasks, where the task data size of the file copy task is 10 mbytes (megabytes), the task data size of one file delete task is 5 mbytes, and the task data size of the other file delete task is 13 mbytes, then the number of tasks for the file processing task is three, and the task data size of the file processing task is 28 mbytes.
If the frequency of the CPU is directly adjusted to the maximum under the condition that the number of the file processing tasks is small and/or the size of the task data is small, the CPU resource is wasted, and the electricity consumption of the electronic equipment is accelerated. The CPU frequency is correspondingly adjusted according to the number of the tasks with heavy file processing tasks and/or the size of the task data, so that the more suitable CPU frequency can be improved, the operation speed of the file processing tasks is increased, and meanwhile, redundant resource waste is avoided.
And step 120, running a file processing task on a big core of the CPU, wherein the MTP driver continuously detects the file processing task.
The CPU is a multi-core CPU, namely, a plurality of complete cores are integrated in one CPU, and the multi-core CPU can be a four-core CPU or an eight-core CPU. The multi-core CPU is provided with a plurality of cores, wherein the cores comprise a plurality of large cores and a plurality of small cores, the large cores have higher running performance, and the small cores have lower running performance. The file processing task is operated on the big core, so that the speed of the file processing task can be increased.
The MTP driver continuously detects the file processing task, i.e., continuously detects the progress of the file processing task. Since the number and size of the file processing tasks are unpredictable and the running time of the file processing tasks is not known. If the performance output of the CPU is adjusted to the maximum for a long time, the resource waste of the CPU and the power consumption may be caused after the file processing task is finished. If the performance output of the CPU is set to be increased for a time interval, it may happen that the time interval ends but the file processing task is still running, which may slow down the processing speed of the subsequent stage of the file processing task. Therefore, the MTP driver continuously detects the file processing task, the operation time of the file processing task can be accurately judged, and the performance output of the CPU is reduced when the end of the file processing task is detected. Therefore, the running speed of the file processing task can be improved, the waste of CPU resources can be reduced, and the power consumption can be reduced.
And step 130, when the MTP driver detects that the file processing task is finished, reducing the performance output of the CPU.
When the MTP driver detects that the file processing task is finished, the MTP driver performs CPU scheduling again, including: reducing the performance output of the CPU. Reducing the performance output of the CPU may be reducing the frequency of the CPU, and optionally reducing the frequency of the CPU to a frequency before invoking the MTP drive to turn on the CPU multi-core and improve the performance output operation of the CPU.
Before the performance output operation of the CPU is improved, the frequency of the CPU is the frequency which accords with the running condition of the CPU at the moment, the performance output of the CPU is reduced to the frequency, and the performance output which accords with the running condition of the CPU can be recovered after the file processing task is finished.
Optionally, the method further comprises, after reducing the performance output of the CPU: and determining whether to shut down the CPU multiple cores according to the current system load, and adjusting the frequency of the CPU.
The CPU multi-core is determined whether to be closed or not according to the current system load, and the frequency of the CPU is adjusted, so that the performance output of the CPU is more consistent with the current running state of the CPU. Since a user may start and run a new application using the electronic device during the running of the file processing task, the corresponding CPU runs a new task process during the running of the file processing task, resulting in a change in system load. Therefore, the performance output of the CPU is readjusted according to the system load, and whether the multi-core is closed or not is judged; the running state of the CPU after the file processing task is processed can be more stable, and no redundant resource waste is caused.
Because the system determines whether to close the CPU multi-core according to the actual system load after the file operation is finished, the frequency of the CPU is firstly reduced to the frequency before the MTP drive is called to open the CPU multi-core and the performance output operation of the CPU is improved. And when the system determines whether to close the CPU multi-core according to the actual system load after the file operation is finished, simultaneously, the frequency of the CPU is adjusted according to the actual system load. The frequency of the CPU is reduced, and then the frequency is adjusted according to the actual load of the system, so that the power consumption of the electronic equipment can be reduced.
Alternatively, as shown in fig. 3, running a file processing task on a large core of a CPU may be implemented by:
and step 121, judging whether the CPU has an idle large core, if so, executing step 1210, and if not, executing step 122.
and 1210, operating the file processing task on the big core of the CPU.
If the number of task processes running on the CPU is large, all the big cores have running tasks, and no idle big core exists, the running state of the tasks on the big cores on the CPU is continuously detected, and when the task currently running on any one big core is detected to be finished, the file processing task is run on the big core. So that the progress of the file processing task can be run on the big core as soon as possible. Optionally, if the CPU has neither an idle large core nor an idle small core, the task running states of the large core and the small core of the CPU are continuously detected until the idle large core or the idle small core occurs, and the file processing task is run on the idle large core or the idle small core. Optionally, before the task currently running on the big core of the CPU is finished, the file processing task is run on the idle small core; and when detecting that the task currently running on any one large core is finished, transferring the file processing task from the small core to the large core to run. And adjusting the operation of the file processing task according to the task operation state of the CPU, and placing the file processing task on a big core of the CPU to operate as much as possible.
In another embodiment, as shown in FIG. 4, running a file processing task on a large core of a CPU may also be implemented by:
and step 121, judging whether the CPU has an idle big core, if so, executing step 1210, and if not, executing step 123.
And 123, continuously detecting the task running state of the big core of the CPU, judging whether a queued task exists on the big core when detecting that the task currently running on the big core of the CPU is finished, if not, executing a step 1210, and if so, executing a step 124.
And step 124, judging whether the queued task is a target application operated in the foreground, if so, executing step 125, and if not, executing step 1210.
And 1210, operating the file processing task on the big core of the CPU.
The task process running on the CPU can have queued tasks in addition to the currently running task process, and the kernel can schedule the tasks of the CPU according to the system load. Under normal conditions, when a currently running task on a big core of the CPU is finished, the kernel can run the queued task on the big core. And when a file processing task exists, the file processing task is inserted to occupy a large core for running, namely the file processing task occupies the large core before the queued task, and the queued task runs on the large core until the progress of the file processing task is finished. However, if the queued task is a target application running in the foreground, the file processing task is queued to occupy a large kernel, which results in poor running status of the target application running in the foreground, and inconvenience is directly brought to the user.
The target application comprises an application with higher requirement on a running environment, an instant application or an application with time consistency of interactive presentation. The applications with higher requirements on the operating environment include applications occupying a CPU proportion higher than a set proportion, such as a 3D game application, a modeling simulation application or a picture processing application, which have higher requirements on the operating conditions of the CPU, and need to run on a large core to normally operate, otherwise, the applications are easily stuck or crashed, and the operating data of the user may be lost.
The instant applications include instant messaging applications or network games, which have high requirements on timeliness, such as FaceTime, and when video calls are carried out, if the running environment cannot meet the requirements of the instant messaging applications due to queue insertion, the quality of the video calls will be affected, and inconvenience is brought to the operation of users.
The application with time consistency of interactive presentation comprises a video application or a music application, namely the interactive presentation which needs time consistency in the application use process of a user. For example, when a video application plays a video, a continuous and stable playing condition is required, and if the running environment of the video application cannot be guaranteed, the video playing is jammed or the picture speed is not uniform, which may also greatly affect the use of the user.
Therefore, when the task queued on the big core of the CPU is the target application of foreground operation, the operation of inserting the file processing task to occupy the big core is not performed, but the queued task is run on the big core, and the task running state of the big core of the CPU is continuously detected. And running the file processing task on the idle large core until the next idle large core appears and no queued task exists on the idle large core or the queued task on the idle large core is not the target application of foreground operation. Therefore, the speed of the file processing task can be increased, and meanwhile, the use operation of the user in the foreground is not influenced.
