With the continuous development of science and technology, electronic equipment has more and more functions and more applications resident in the background of the electronic equipment. In general, when there are many programs running at the same time, the system can schedule resources according to the scheduling priority in the resource scheduling policy. For example, when a user swipes a WeChat friend circle in the foreground using a cell phone, many applications in the background of the cell phone are running in the background, such as QQ receiving messages in the background, flashing a flash to download movies in the background, and so on. The resource scheduling policy of the current system can preferentially guarantee the operation of foreground application, that is, the foreground application can preferentially obtain resources, for example, the WeChat of the foreground is preferentially operated on the CPU big core and the scheduling priority of the CPU big core is improved, and the background application limits the obtaining of resources, for example, the QQ or the thunder of the background is limited on the CPU small core and the scheduling priority of the CPU small core is reduced.
However, the problem of priority reversal is greatly aggravated by adopting the resource scheduling strategy, that is, a task with a high priority cannot run because of being blocked by a task with a low priority, and a task with a high priority can run only after a task with a low priority is run to release a system lock, thereby causing the problem of system deadlock.

Detailed Description
The technical solutions in the embodiments of the present application will be described below in detail with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/", and generally means that the former and latter related objects are in an "or" relationship.
The task scheduling method provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
As shown in fig. 1, a task scheduling method provided in an embodiment of the present application includes the following steps 101 to 102, which are described in detail below.
And 102, running the first task under the condition that the parameter information meets a preset condition.
In this embodiment, in a system of an electronic device, there are often situations where multiple tasks are executed at the same time. For example, in the process of playing a game using a mobile phone, a game application is run in the foreground, and at the same time, applications such as "setting" application, "music" application, "file management" may also be run in the background. However, due to the limitation of some hardware resources of the electronic device, for example, only one UFS memory for storing data is in the mobile phone, so that when multiple tasks call system resources, only one task can be called at the same time. Wherein, the key lock can be set at the entrance of the calling data to ensure that only one task reads the system resource at the same time. That is, there is only one task acquiring the critical lock at a time.
After the key lock is set at the entrance of the calling data, under the condition that a plurality of tasks need to acquire system resources, because only one task acquires the key lock at the same time, the plurality of tasks sequentially acquire the key lock according to the time sequence. And after any task in the plurality of tasks acquires the key lock, the task is marked to enter a waiting operation or a critical operation region, and the system resource corresponding to the task is occupied. Generally, a task that is earlier in time to acquire the key lock may be executed in preference to a task that is later in time to acquire the key lock, and thus, the plurality of tasks may be executed in chronological order to acquire the key lock.
If a task needs to be preferentially run, when the task acquires a key lock, the task can be marked by target identification information, and the target identification information is used as one item of parameter information of the task. The target identification information may be used to indicate that the task corresponding to the target identification information is a special task. For example, the target identification information may be a special character by which a special task that needs to be preferentially run is marked. It will be understood by those skilled in the art that the target identification information is not particularly limited thereto.
And acquiring the parameter information of the first task under the condition that the first task acquires the key lock. And under the condition that the parameter information comprises the target identification information, determining that the first task is a special task meeting a preset condition. And under the condition that the parameter information does not comprise the target identification information, determining that the first task does not meet a preset condition. Wherein the first task is any one of the plurality of tasks.
And under the condition that the first task is determined to be a special task meeting the preset condition, the first task is operated on the CPU, and other tasks with high priority are forbidden to operate.
For example, task 1 and task 2 acquire the key lock according to time sequence, and if neither task 1 nor task 2 is marked with the identification information, then task 1 and task 2 are run according to the time sequence of acquiring the key lock. If the task 2 is a special task marked by a special character, the task 2 runs before the task 1 under the condition that the task 2 acquires the key lock with the identification information.
According to the embodiment of the application, the key lock is set, so that only one task acquisition Guan Jiansuo exists at the same time, the multiple tasks can be operated in a time sequence by acquiring the key lock when the multiple tasks are operated simultaneously, and the problem of system congestion is avoided. The method comprises the steps that parameter information of a first task is obtained under the condition that the first task obtains a key lock, the first task is operated under the condition that the parameter information meets preset conditions, the first task with target identification information can be preferentially operated, and therefore the waiting time of the first task for operation is shortened, and the problem that a system is blocked due to priority reversal in the related technology is avoided.
In an embodiment, in order to avoid the problem that other tasks cannot normally run due to long-time running of a special task and further reduce user experience, the embodiment of the present application further provides a method for controlling task scheduling based on the identification duration of the target identification information. That is, in a case that the parameter information includes target identification information, the parameter information satisfying a preset condition further includes: the identification duration of the target identification information is less than or equal to a preset duration.
In this embodiment, when a plurality of tasks acquire a key lock, the identification duration of a specific task marked with target identification information may be recorded while marking the specific task with the target identification information. And, associating the identification duration with the corresponding target identification information.
When a first task acquires a key lock, acquiring parameter information of the first task, and determining whether the parameter information of the first task comprises target identification information. And under the condition that the parameter information of the first task comprises target identification information, determining whether the identification time length of the target identification information is less than or equal to preset time length. And under the condition that the identification time length of the target identification information is less than or equal to the preset time length, determining that the parameter information meets the preset condition, further forbidding other tasks with high priority to run, and running the first task.
According to the embodiment of the application, when the parameter information includes the target identification information, the parameter information satisfying the preset condition further includes: the identification time length of the target identification information is less than or equal to the preset time length, so that the influence on the operation of other tasks due to the long-time operation of a special task can be avoided, the operation speed of the system is further influenced, and the user experience is reduced.
In one embodiment, after the obtaining of the parameter information of the first task, the method further includes:
step 201, running a second task with priority higher than that of the first task when the parameter information does not meet the preset condition; wherein the parameter information not meeting the preset condition comprises one of the following items: the parameter information does not include the target identification information, the parameter information includes the target identification information, but the identification duration of the target identification information is greater than the preset duration;
and 202, after the second task exits from running, running the first task.
In this embodiment, when the parameter information of the first task does not include the target identification information, or when the parameter information includes the target identification information but the identification duration of the target identification information is greater than the preset duration, it is determined that the parameter information of the first task does not satisfy a preset condition.
And running the second task under the condition that the parameter information of the first task does not meet the preset condition and the second task with the priority higher than that of the first task exists. And, while running the second task, the first task is in a wait-to-run state. And after the second task exits from running, running the first task.
For example, task 2 acquires the key lock earlier than task 1, i.e., task 2 has a higher priority than task 1. And the parameter information of the task 1 does not include the target identification information, or the parameter information of the task 1 includes the target identification information but the identification duration of the target identification information is longer than the preset duration. In this case, the parameter information of the task 1 does not satisfy the setting condition, the task 2 is run first according to the priority order, and the task 1 is run after the task 2 is run and quits the running.
According to the embodiment of the application, the second task is operated under the condition that the parameter information of the first task does not meet the set condition and the second task with the priority higher than that of the first task exists, and the first task is operated after the second task quits operation, so that the problem that a system is blocked due to multi-task operation conflict can be solved.
In an embodiment, in order to increase the operating speed of the system and reduce the power consumption of the system, a condition for triggering acquisition of parameter information of the first task is further set in the embodiment of the present application. That is to say, in the case that the first task acquires the key lock, acquiring the parameter information of the first task includes:
301, when the first task acquires Guan Jiansuo and the first task occupies a system resource, acquiring parameter information of the first task;
step 302, when the first task acquires Guan Jiansuo and a third task occupies the system resource, waiting for the first task to be awakened, and acquiring parameter information of the first task when the first task is awakened; wherein the first task is awakened if the third task releases the system resources.
In this embodiment, two conditions for triggering acquisition of parameter information of the first task are set:
the first condition is as follows: and acquiring parameter information of the first task when the first task acquires Guan Jiansuo and occupies system resources.
When a first task acquires Guan Jiansuo and the first task does not occupy system resources, it is described that the first task may be blocked, and at this time, detection is not performed on whether parameter information of the first task meets a preset condition.
When a first task acquires Guan Jiansuo and occupies system resources, it needs to be determined whether the first task is a special task meeting preset conditions, and then the priority order of the first task and other tasks needing to be run is determined. Namely, the parameter information of the first task is acquired to detect whether the parameter information of the first task meets a preset condition.
And a second condition: when the first task acquires Guan Jiansuo and a third task occupies the system resource, waiting for the first task to be awakened, and acquiring parameter information of the first task when the first task is awakened; wherein the first task is woken up on a condition that the third task releases the system resources.
The second condition is for the case where the first task acquired Guan Jiansuo and the third task occupied system resources, in which case the operation of the first task may be blocked. For example, the first task is a lock nested configuration, and before the first task is executed, not only the key lock needs to be acquired as an external lock, but also an internal lock for locking the system resource it is engaged with. After the first task acquires the key lock, the internal lock is occupied by the third task and cannot be acquired. In this case, the operation of the first task is blocked.
In the case where the execution of a first task is blocked, other tasks are executed first in order of priority, the first task being in a sleep state waiting to be woken up. Wherein the other tasks include the third task. And after the third task is finished and quits running, releasing the internal lock. At this time, the first task is awakened, and the first task can acquire the internal lock to occupy the system resource. And acquiring the parameter information of the first task under the condition that the first task occupies the system resource so as to detect whether the parameter information of the first task meets the preset condition.
According to the embodiment of the application, the condition for triggering the acquisition of the parameter information of the first task is further set, so that the running speed of a system can be increased, and the power consumption of the system can be reduced. And when the first task is blocked, other tasks are operated firstly, the first task is awakened under the condition that the third task releases the system resources, the parameter information of the first task is obtained, the problem that other tasks with low priority cannot be operated due to the blockage of the task with high priority can be avoided, and the system operation speed is improved.
In one embodiment, after the running the first task, the method further comprises:
clearing the parameter information of the first task after the first task releases the key lock.
In this embodiment, after the first task is run, the first task releases Guan Jiansuo, and clears the parameter information of the first task. When the parameter information includes target identification information, the clearing of the parameter information of the first task is to clear the target identification information in the parameter information of the first task. And under the condition that the parameter information comprises target identification information and identification duration of the target identification information, the parameter information of the first task is cleared by the target identification information and the identification duration of the target identification information in the parameter information of the first task.
According to the embodiment of the application, after the first task releases the key lock, the parameter information of the first task is cleared, so that the target identification information can be prevented from influencing the normal operation of other tasks after the task with the target identification information is operated.
In one embodiment, after the obtaining of the parameter information of the first task, the method further includes:
step 401, when a set event occurs and the parameter information of the first task includes the target identification information, acquiring an identification duration of the target identification information.
In this embodiment, the setting event may be a periodically occurring event. For example, the set event may be a Tick interrupt event, which is understood to be a periodic clock interrupt, typically 4 milliseconds each in a cellular system. The Tick interruption can realize that the time information of task operation in the system is periodically updated, and then whether the currently operated task needs to be scheduled or not is determined based on the time information of the task operation.
In the running process of the system, the overtime judgment of the identification duration can be carried out on the special task comprising the target identification information in the system under the condition that a set event occurs.
Step 402, removing the target identification information in the parameter information of the first task when the identification duration of the target identification information is greater than the preset duration.
In this embodiment, when the identification duration of the target identification information is longer than the preset duration, that is, the time for running the first task is too long, the running of the first task is abnormal, and a dead cycle may be involved. In this case, the target identification information in the parameter information of the first task is cleared, and the first task is reordered according to the time when it acquires the key lock, so as to avoid running all the time.
According to the embodiment of the application, under the condition that a set event occurs and the parameter information of the first task comprises the target identification information, the identification duration of the target identification information is obtained; and under the condition that the identification time length of the target identification information is longer than the preset time length, the target identification information in the parameter information of the first task is removed, so that the problem that other tasks cannot run due to abnormal task running can be avoided, and the running speed of the system is improved.

In this embodiment, in step 24, if it is detected that the parameter information of the first task includes the target identification information, and the identification duration of the target identification information is less than or equal to the preset duration t, the CPU is prohibited from switching to the second task, and the CPU runs the first task, so that the critical section time of the first task can be shortened. In step 25 and step 26, if it is detected that the parameter information of the first task does not include the target identification information, or the parameter information of the first task includes the target identification information but the identification duration exceeds the preset duration t, the second task with high priority is executed first, and when the second task is executed, the CPU will switch back to execute the first task, so as to avoid the problem of system jamming caused by priority inversion.

And 32, waiting for the first task to be awakened when the first task acquires Guan Jiansuo and the third task occupies the system resources.
In this embodiment, the first task acquires the key lock, and marks that the first task enters the critical section. At this time, the third task occupies the system resource that the first task needs to commission, and the first task is blocked, and at this time, the first task is in a state waiting to be awakened. The CPU will run other tasks, wherein the other tasks include a third task.
In this embodiment, the first task is awakened when the third task exits from running and releases the system resource. And acquiring the parameter information of the first task under the condition that the first task is awakened so as to judge whether the parameter information of the first task meets a preset condition.
And 35, if the parameter information of the first task comprises the target identification information and is not overtime, immediately switching the CPU back to the operation of the first task.
And step 36, if the parameter information of the first task does not include the target identification information, or the parameter information of the first task includes the target identification information but the identification duration is overtime, judging whether to switch to other tasks to operate or not according to whether other tasks with high priority need to operate or not.
And step 37, after other tasks with high priority quit running, switching the CPU back to the first task to run.
And step 39, clearing the target identification information of the first task.
In this embodiment, when the first task is blocked, the CPU is yielded actively, and the current CPU will run the third task. And when the third task exits from running, the first task is awakened. And under the condition that the first task is awakened, judging whether the parameter information of the first task meets a preset condition. If the parameter information of the first task comprises the target identification information and the timeout does not exist, the current CPU is immediately switched back to run the first task, so that the problem that other tasks cannot be run due to the blockage of the task with high priority is avoided, and the running speed of the system can be increased.

In this embodiment, tick interrupt may be used to perform timeout detection on a task with target identification information in the system, and if it is detected that the identification duration of the target identification information exceeds the preset duration, it indicates that the task occupies the CPU for a long time, and abnormal operation may occur, which falls into a dead cycle. The task is queued again and then the priority is lower, so that the task can be queued again and the system can run other tasks. Therefore, the problem that other tasks cannot run due to abnormal running of the tasks can be avoided, and the running speed of the system is improved.
