Description

Technical Field

[0001] This application belongs to the field of communication technology, and specifically relates to a resource allocation method and apparatus. Background Technology

[0002] To meet consumers' ever-increasing demands for imaging capabilities, imaging technology in smartphones and other electronic devices has been developing rapidly in recent years. From large-sensor cameras, multi-camera setups, and micro-gimbals to image signal processor (ISP) algorithms, the computational demands on each module of the System on a Chip (SOC) are increasing. While significantly improving photo quality, this has inevitably introduced performance bottlenecks. In particular, the Central Processing Unit (CPU), as an important sub-module of the SOC, is severely overloaded. Therefore, it is necessary to optimize CPU resource scheduling.

[0003] In related technologies, a control group (cgroup) mechanism is introduced. Figure 1 One of the schematic diagrams of the control group mechanism, such as Figure 1 As shown, place the camera module in the foreground group or a custom control group, other background applications in the background group, and system services in the system group, and allocate CPU resources proportionally according to the shares value (score) of each group; Figure 2 This is the second schematic diagram of the control group mechanism, as shown below. Figure 2 As shown, the five threads within the dashed box 101 are the threads corresponding to the camera module, and the threads within the dotted-line box 102 are the threads of the root cgroup. The weights of the five threads of the camera module are 1:2:1:2:1, with 3 / 7 of the threads executing on CPU0 and 4 / 7 of the threads executing on CPU1. Figure 1It can be seen that on CPU0, the two threads running the camera module and the root cgroup thread have a share value of 1024*3 / 7 = 439, and the root cgroup thread has a share value of 1024. Therefore, the CPU resources allocated to the camera module on CPU0 are: 439 / (1024+439) = 30%, and the resources allocated to the root cgroup thread on CPU0 are: 1-30% = 70%. On CPU1, the three threads running the camera module, as well as root cgroup thread 1 and root cgroup thread 2 have a share value of 1024*4 / 7 = 585, the share value of root cgroup thread 1 is 1024, and the share value of root cgroup thread 2 is 512. Therefore, the CPU resources allocated to the camera module on CPU1 are: 585 / (1024+585+512) = 28%. The resources allocated to thread 1 in cgroup are: 1024 / (1024+585+512) = 48%; the resources allocated to thread 2 in the root cgroup on CPU1 are: 512 / (1024+585+512) = 24%, thus realizing the allocation of CPU resources according to the proportion of shares value of each group.

[0004] However, in the aforementioned technologies, CPU resources cannot be allocated in real time when the CPU frequency is limited due to high temperatures or when background applications in the background group occupy fluctuating CPU resources. Summary of the Invention

[0029] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0031] The resource allocation method, resource allocation device, electronic device, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0032] Figure 3 This is one of the flowcharts illustrating the resource allocation method provided in the embodiments of this application, such as... Figure 3 As shown, the resource allocation method includes the following steps 301, 302, and 303:

[0033] Step 301: Obtain the computing power ratio of at least one target module in the target shooting scene.

[0034] The shooting scenarios of the electronic device include portrait photography, professional photography, ordinary photography, night scene photography, and video recording. The at least one target module includes a shooting module, an image preview module, a system service module, and a background module, and the shooting module, the image preview module, the system service module, and the background module are located in different control groups.

[0035] For example, a corresponding computing power model is pre-designed for each shooting scenario, and the shooting scenarios and computing power models are stored in correspondence. The computing power model is used to indicate the computing power ratio of each target module. Figure 4 This is a schematic diagram of the computing power model corresponding to the portrait photography scene provided in the embodiments of this application, such as... Figure 4 As shown, in a portrait photography scenario, the computing power of the shooting module 301 can account for 30%, the computing power of the image preview module 302 can account for 30%, the computing power of the system service module 303 can account for 30%, and the computing power of the background module 304 can account for 10%. Therefore, when the target shooting scene is identified, the computing power model corresponding to the target shooting scene can be obtained, which means the computing power percentage of each target module in the target shooting scene can be obtained.

[0036] Step 302: Based on the computing power ratio of each target module, determine the scheduling threshold of the control group to which each target module belongs.

[0037] For example, when obtaining the computing power percentage of each target module in the target shooting scene, the scheduling threshold of the control group to which the target module belongs is determined based on the computing power percentage of the target module. For instance, by default, the control group to which the shooting module belongs, the control group to which the image preview module belongs, the control group to which the system service module belongs, and the control group to which the background module belongs all share CPU resources, that is, the computing power percentage of the four control groups is 25% each, and the scheduling threshold of the four control groups, that is, the shares value, is 1024 by default. Taking the target shooting scene as a portrait photography scene as an example, from the computing power model corresponding to the portrait photography scene, we can know that... If the computing power of the shooting module accounts for 30%, then the scheduling threshold of the control group where the shooting module is located is 1024*30% / 25%≈1228; if the computing power of the image preview module accounts for 30%, then the scheduling threshold of the control group where the image preview module is located is 1024*30% / 25%≈1228; if the computing power of the background module accounts for 10%, then the scheduling threshold of the control group where the background module is located is 1024*10% / 25%=496; if the computing power of the system service module accounts for 30%, then the scheduling threshold of the control group where the system service module is located is 1024*30% / 25%≈1228.

[0038] It should be noted that the above method for calculating the scheduling threshold of the control group to which the target module belongs based on the computing power ratio of the target module is only an example. In practice, it can be dynamically calculated based on CPU temperature rise frequency limiting, CPU load, or more control groups. This invention will not elaborate further here.

[0039] Step 303: Allocate target CPU resources to the corresponding control group based on the scheduling threshold of each control group.

[0040] For example, when the scheduling threshold of the control group where each target module is located in the target shooting scene is obtained, target CPU resources are allocated to the corresponding control group based on each scheduling threshold; for example, if the scheduling threshold of the control group where the shooting module is located is 1228, then 30% of the CPU resources are allocated to the control group where the shooting module is located.

[0041] The resource allocation method provided in this application first obtains the computing power ratio of each target module in the target shooting scene, then determines the scheduling threshold of the control group to which each target module belongs based on the computing power ratio of each target module, and allocates target CPU resources to the corresponding control group based on the scheduling threshold of each control group, thereby realizing the real-time allocation of CPU resources of each control group in different shooting scenes.

[0042] In one embodiment, Figure 5 This is a second schematic flowchart of the resource allocation method provided in the embodiments of this application, such as... Figure 5 As shown, step 303 above can be implemented through the following steps:

[0043] Step 3031: If the CPU temperature is determined to be greater than or equal to the preset temperature, adjust the scheduling threshold of the corresponding control group based on the priority of each target module.

[0044] The preset temperature can be set according to needs, such as a preset temperature of 50 degrees.

[0045] For example, the remaining CPU resources are related to the CPU temperature. When the CPU temperature is high, the remaining CPU resources will decrease to ensure normal CPU operation; when the CPU temperature is low, the remaining CPU resources will increase. Therefore, when obtaining the scheduling threshold of the control group to which the corresponding target module belongs based on the computing power ratio of each target module, the CPU temperature can be further obtained. If the CPU temperature is determined to be greater than or equal to the preset temperature, since the remaining CPU resources decrease, the scheduling threshold of at least one control group needs to be lowered to reduce the allocation of CPU resources to the control group with the lowered scheduling threshold, so that the remaining CPU resources match the actual CPU resources required by each control group. Specifically, a priority can be set for each control group first, and the control group with the highest priority will start lowering the corresponding scheduling threshold first. For example, if the priority of the background module is higher than that of the shooting module, and the priority of the shooting module is higher than that of the image preview module and the system service module, then the scheduling threshold of the control group to which the background module belongs can be lowered first.

[0046] Step 3032: Allocate target CPU resources to the corresponding control group based on the adjusted scheduling threshold of each control group.

[0047] For example, after adjusting the scheduling threshold of a control group, target CPU resources can be allocated to the corresponding control group based on the adjusted scheduling threshold of each control group; it is understood that if only the scheduling threshold of one control group is adjusted, the scheduling thresholds of other control groups will remain the previous scheduling thresholds.

[0048] The resource allocation method provided in this application, when obtaining the scheduling threshold of the control group to which the corresponding target module belongs based on the computing power ratio of each target module, can further adjust the scheduling threshold of the relevant control group based on the CPU temperature and the priority of each target module, thereby realizing the dynamic real-time adjustment of the scheduling threshold and making the allocation of remaining CPU resources more reasonable.

[0049] In one embodiment, the target module includes a shooting module and a background module; step 3031 above can be implemented in the following ways:

[0050] Acquire the first CPU resources required by all control groups;

[0051] If it is determined that the first CPU resource is greater than the remaining CPU resource, the scheduling threshold of the control group where the background module is located is reduced based on a first preset ratio, and the second CPU resource required by all control groups is reacquired; the remaining CPU resource is the available CPU resource corresponding to the CPU temperature.

[0052] If it is determined that the second CPU resource is greater than the remaining CPU resource, the scheduling threshold of the control group to which the shooting module is located is reduced based on the second preset ratio.

[0053] The specific values ​​of the first preset ratio and the second preset ratio can be set according to the requirements, for example, both the first preset ratio and the second preset ratio can be 80%.

[0054] For example, if the CPU temperature is determined to be greater than or equal to a preset temperature, in order to ensure that the CPU can work normally, it is necessary to reduce the total CPU resources to obtain the remaining CPU resources. Therefore, if the CPU temperature is determined to be greater than or equal to the preset temperature, firstly, the CPU resources required by each control group are obtained. Then, the sum of the CPU resources required by each control group is taken as the first CPU resources required by all control groups. The first CPU resources required by all control groups are compared with the remaining CPU resources. If it is determined that the first CPU resources required by all control groups are greater than the remaining CPU resources, it means that the remaining CPU resources cannot meet the needs of each control group. At this time, in the shooting scenario, in order to ensure the performance of the shooting function, the scheduling threshold of the control group where the background module is located can be reduced first based on a first preset ratio, thus reducing the CPU resources allocated to the control group where the background module is located. Then, the second CPU resources required by all control groups are obtained. If the second CPU resources required by all control groups are still greater than the remaining CPU resources, the scheduling threshold of the control group where the shooting module is located is reduced again based on a second preset ratio, prioritizing the CPU resources of the control group where the image preview module is located and the control group where the system service module is located. For example, assuming the total CPU resources are t and the CPU resources required by all control groups are c, then the CPU load is c / t. When the CPU temperature is greater than or equal to the preset temperature, the total CPU resources t decrease, resulting in a higher CPU load. At this time, the scheduling threshold of the control group where the background module is located is lowered first, thus reducing the CPU resources allocated to the control group where the background module is located.

[0055] The resource allocation method provided in this application embodiment can prioritize reducing the scheduling threshold of the control group where the background module is located when it is determined that the first CPU resources required by all control groups are greater than the remaining CPU resources. If the second CPU resources required by all newly acquired control groups are still greater than the remaining CPU resources, the scheduling threshold of the control group where the shooting module is located will be further reduced to prioritize ensuring the CPU resources of the control group where the image preview module is located and the control group where the system service module is located, so as to ensure that the image preview is smooth and does not lag during shooting.

[0056] In one embodiment, Figure 6 This is the third flowchart illustrating the resource allocation method provided in the embodiments of this application, as shown below. Figure 6 As shown, step 303 above can be implemented through the following steps:

[0057] Step 3033: If the first load of the CPU is determined to be greater than the preset percentage, adjust the scheduling threshold of the corresponding control group based on the priority of each target module.

[0058] The specific value of the preset percentage can be set based on the needs, such as a preset percentage of 100%.

[0059] For example, when obtaining the scheduling threshold of the control group to which the corresponding target module belongs based on the computing power ratio of each target module, the first load of the CPU can be further obtained. If the first load of the CPU is greater than or equal to the preset ratio, it indicates that the load is excessive. For example, assuming the total CPU resources are t and the CPU resources required by all control groups are c, the CPU load is c / t. When the number of tasks in the control group increases, the CPU resources c increase, resulting in a higher CPU load.

[0060] When the CPU load increases, the scheduling threshold of at least one control group needs to be lowered to reduce the allocation of CPU resources to the control group whose scheduling threshold has been lowered, so that the CPU load is less than or equal to a preset percentage. Specifically, a priority can be set for each control group first, and the control group with the highest priority will start lowering its corresponding scheduling threshold first. For example, if the priority of the background module is higher than that of the shooting module, and the priority of the shooting module is higher than that of the image preview module and the system service module, then the scheduling threshold of the control group where the background module is located can be lowered first.

[0061] Step 3034: Allocate target CPU resources to the corresponding control group based on the adjusted scheduling threshold for each control group.

[0062] For example, after adjusting the scheduling threshold of a control group, target CPU resources can be allocated to the corresponding control group based on the adjusted scheduling threshold of each control group; it is understood that if only the scheduling threshold of one control group is adjusted, the scheduling thresholds of other control groups will remain the previous scheduling thresholds.

[0063] The resource allocation method provided in this application, when obtaining the scheduling threshold of the control group to which the corresponding target module belongs based on the computing power ratio of each target module, can further adjust the scheduling threshold of the relevant control group based on the first load of the CPU and the priority of each target module, thereby realizing the dynamic real-time adjustment of the scheduling threshold and making the allocation of remaining CPU resources more reasonable.

[0064] In one embodiment, the target module includes a shooting module and a background module; step 3033 above can be implemented in the following ways:

[0065] The scheduling threshold of the control group where the background module is located is reduced based on the third preset ratio, and the second load of the CPU is reacquired.

[0066] If the second load of the CPU is determined to be greater than the preset percentage, the scheduling threshold of the control group to which the shooting module is located is reduced based on the fourth preset percentage.

[0067] The specific values ​​of the third and fourth preset ratios can be set according to requirements, for example, both the third and fourth preset ratios can be 80%.

[0068] For example, if the CPU's first load is determined to be greater than a preset percentage, it indicates excessive load. In this case, during the shooting scenario, to ensure the performance of the shooting function, the scheduling threshold of the control group containing the background module can be reduced based on a third preset percentage. This reduces the CPU resources allocated to the control group containing the background module, thus reducing the resources occupied by tasks within that control group and increasing the time required for task completion, thereby reducing the CPU load per unit time. Then, the CPU's second load is obtained. If the second CPU load is still greater than a preset percentage, the scheduling threshold of the control group containing the shooting module is further reduced based on a fourth preset percentage. This reduces the CPU resources allocated to the control group containing the shooting module, further reducing the resources occupied by tasks within that control group and increasing the time required for task completion, thus further reducing the CPU load per unit time. This prioritizes ensuring CPU resources for the control groups containing the image preview module and the system service module. Taking the background module running instant messaging software 1 and instant messaging software 2, and the foreground module running a portrait photography scene as an example, when instant messaging software 1 and instant messaging software 2 are running in the background, 30% of the CPU computing power resources can be allocated to the control group where the shooting module is located, 30% of the CPU computing power resources can be allocated to the control group where the image preview module is located, and 10% of the CPU computing power resources can be allocated to the control group where the background module is located. When no application is running in the background, 40% of the CPU computing power resources can be allocated to the control group where the shooting module is located, and 30% of the CPU computing power resources can be allocated to the control group where the image preview module is located. The 30% CPU computing power resources can ensure smooth preview. When no application is running in the background, more CPU computing power resources can be allocated to the control group where the shooting module is located, so that the image can be completed faster.

[0069] The resource allocation method provided in this application embodiment can prioritize reducing the scheduling threshold of the control group where the background module is located when the first CPU load is determined to be greater than the preset percentage. If the second CPU load that is re-acquired is still greater than the preset percentage, the scheduling threshold of the control group where the shooting module is located will be further reduced to prioritize the CPU resources of the control group where the image preview module is located and the control group where the system service module is located, so as to ensure that the shooting module can take pictures or record videos quickly.

[0070] For example, Figure 7 This is a schematic diagram of the resource allocation framework provided in the embodiments of this application, such as... Figure 7 As shown, the resource allocation framework includes Energy Aware Scheduling (EAS) 701, small core clusters 702, large core clusters 703, super-large core clusters 704, cgroup mechanism 705, and camera dynamic performance framework 706. Among them, EAS scheduling 701 is used to control the output of actual CPU resources based on CPU temperature rise power consumption strategy, and allocate CPU resources to small core clusters 702, large core clusters 703, and super-large core clusters 704. The cgroup mechanism 705 can specifically divide the shooting module into camera-snap group 707, the image preview module into camera-preview group 708, the system service module into system group 709, and the background module into background group 710. The camera dynamic performance framework 706 allocates corresponding CPU resources to each control group based on CPU temperature and CPU load.

[0071] It should be noted that this application does not limit the number of control groups, and in practical applications, other control groups may also be included.

[0077] The resource allocation device provided in this application first obtains the computing power ratio of each target module in the target shooting scene, then determines the scheduling threshold of the control group to which each target module belongs based on the computing power ratio of each target module, and allocates target CPU resources to the corresponding control group based on the scheduling threshold of each control group, thereby realizing the real-time allocation of CPU resources of each control group in different shooting scenes.

Based on the scheduling threshold of each control group, target CPU resources are allocated to the corresponding control group, thereby realizing the real-time allocation of CPU resources of each control group in different shooting scenes.

[0103] Optionally, the at least one target module includes a shooting module, an image preview module, a system service module, and a background module, and the shooting module, the image preview module, the system service module, and the background module are located in different control groups.

[0104] Optionally, the processor 1010 is further configured to adjust the scheduling threshold of the corresponding control group based on the priority of each target module when it is determined that the temperature of the CPU is greater than or equal to a preset temperature.

[0105] Target CPU resources are allocated to the corresponding control group based on the adjusted scheduling threshold for each control group.

[0106] In the above implementation, when the scheduling threshold of the control group to which the corresponding target module belongs is obtained based on the computing power ratio of each target module, the scheduling threshold of the relevant control group can be further adjusted based on the CPU temperature and the priority of each target module, thereby realizing the dynamic real-time adjustment of the scheduling threshold and making the allocation of the remaining CPU resources more reasonable.

[0107] Optionally, the target module includes a shooting module and a background module; the processor 1010 is also used to acquire the first CPU resources required by all control groups;

[0108] If it is determined that the first CPU resource is greater than the remaining CPU resource, the scheduling threshold of the control group where the background module is located is reduced based on a first preset ratio, and the second CPU resource required by all control groups is reacquired; the remaining CPU resource is the available CPU resource corresponding to the CPU temperature.

[0109] If it is determined that the second CPU resource is greater than the remaining CPU resource, the scheduling threshold of the control group to which the shooting module is located is reduced based on the second preset ratio.

[0110] In the above implementation, when it is determined that the first CPU resources required by all control groups are greater than the remaining CPU resources, the scheduling threshold of the control group where the background module is located can be reduced first. If the second CPU resources required by all newly acquired control groups are still greater than the remaining CPU resources, the scheduling threshold of the control group where the shooting module is located is further reduced. Priority is given to ensuring the CPU resources of the control group where the image preview module is located and the control group where the system service module is located, so as to ensure that the image preview is smooth and does not lag during the shooting.

[0111] Optionally, the processor 1010 is further configured to adjust the scheduling threshold of the corresponding control group based on the priority of each target module when it is determined that the first load of the CPU is greater than a preset percentage.

[0112] Target CPU resources are allocated to the corresponding control group based on the adjusted scheduling threshold for each control group.

[0113] In the above implementation, when the scheduling threshold of the control group to which the corresponding target module belongs is obtained based on the computing power ratio of each target module, the scheduling threshold of the relevant control group can be further adjusted based on the first load of the CPU and the priority of each target module, thereby realizing the dynamic real-time adjustment of the scheduling threshold and making the allocation of the remaining CPU resources more reasonable.

[0114] Optionally, the target module includes a shooting module and a background module; the processor 1010 is further configured to reduce the scheduling threshold of the control group to which the background module is located based on a third preset ratio, and to reacquire the second load of the CPU;

[0115] If the second load of the CPU is determined to be greater than the preset percentage, the scheduling threshold of the control group to which the shooting module is located is reduced based on the fourth preset percentage.

[0116] In the above implementation, when the first CPU load is determined to be greater than the preset percentage, the scheduling threshold of the control group where the background module is located can be reduced first. If the second CPU load that is reacquired is still greater than the preset percentage, the scheduling threshold of the control group where the shooting module is located will be reduced again. Priority will be given to ensuring the CPU resources of the control group where the image preview module is located and the control group where the system service module is located, so as to ensure that the shooting module can take pictures or record videos quickly.
