Description

Multi-system resource scheduling method and device

Technical Field

The invention relates to the technical field of terminals, in particular to a resource scheduling method and device for multiple systems.

Background

With the progress of society and the development of science and technology, terminal devices such as smart phones, tablet computers, electronic readers and the like are widely popularized. A considerable number of terminal devices have two operating systems installed therein.

Due to the requirement of fast switching of the operating systems, two operating systems are usually running in the terminal device at the same time. In this case, the terminal device system in which the two operating systems are installed needs to provide more resources, such as processor resources and memory resources, than a single operating system is run, so as to ensure the normal operation of the two operating systems.

On a terminal device, in order to ensure the smooth experience of using an application by a user, when an application is switched from a foreground to a background, resources occupied by the application are often not released, but original resources are continuously occupied. Thus, when a new application is opened and applies for resources, the terminal device allocates corresponding resources from the idle resources to be used by the new application. After a period of operation, the terminal device is often prone to have insufficient idle resources, which requires scheduling resources for the newly created foreground process. The existing dual system has not been configured with an effective resource scheduling method.

The existing resource scheduling method of a single system comprises the following steps: when the idle resources are insufficient, closing a relatively unimportant background process to dispatch the resources for a newly created foreground process to use; when only necessary processes for maintaining the operation system are left in the background process, the relatively unimportant foreground process is closed.

However, if the resource scheduling method of the single system is directly applied to the terminal devices in the dual systems, it is likely to cause confusion of resource scheduling. For example, the operating systems a and B independently adopt the existing resource scheduling method of a single system, and the operating systems a and B are located in the foreground and the background, respectively, on one hand, because the existing dual system is not yet configured with an effective resource scheduling method, the process of the operating system a may occupy less resources, and the process of the operating system B may occupy more resources; on the other hand, when the process of the operating system B occupies more resources and the shortage of idle resources does not occur, the process of the operating system B cannot be closed actively by using the existing resource scheduling method of the single system, so that the resources are scheduled to be used by the operating system A of the foreground. Therefore, the situation of insufficient resources of the operating system of the foreground is easily caused, inconvenience is brought to the user, and the user experience is reduced.

The technical solution of the embodiments of the present invention is specifically described below with reference to the accompanying drawings.

A frame schematic diagram of an internal structure of a terminal device according to an embodiment of the present invention is shown in fig. 1, and includes: a master control system and more than two container systems.

Wherein the two or more container systems comprise a first container system, a second container system, … …, and an Nth container system. N is a positive integer of 2 or more.

The container system in the embodiment of the present invention is an operating system provided in a container created by the Linux container virtualization technology. The operating system may be a Linux operating system or a Unix operating system in the conventional sense, an Android system or an Ubuntu system derived from the Linux operating system, or a Windows system based on a Windows platform. In fact, the container system of the present invention is not limited to the aforementioned exemplary operating systems, and may cover all operating systems capable of operating in a container. For convenience of description, the technical solution of the present invention is described below by taking an Android system as a container system as an example.

The master control system may be the above-mentioned conventional operating system, or may be an operating system obtained by modifying the conventional operating system. The kernel is a kernel, or an enhanced kernel obtained after a functional module is added on the basis of the kernel. Preferably, the master control system may include a kernel; the container system calls or accesses the kernel through the master control system to realize various functions. Or the container system and the master control system share the kernel; the container system and the master control system comprise parts except the kernel in the existing operating system, such as parts of a framework layer and an application layer; both the container system and the master control system can independently call or access the kernel to realize various functions.

The main control system is mainly used for performing foreground and background management on a plurality of container systems, interacting with each container system and the like.

Preferably, the master control system may communicate with the container system through a container channel. Further, the container channel may be a socket channel.

The method for establishing the container channel between the main control system and the container system is described below.

The container system sends a container channel creating request to the master control system, wherein the container channel creating request comprises file descriptors corresponding to the container channel, file permissions, system identifiers of more than two operating systems allowing access to the container channel, the maximum allowed access number, identifiers of descriptors of files to be generated and the like. The two or more operating systems include a container system (that sends a container channel creation request) and an operating system that the container system expects to interact with.

After receiving a container channel creation request of the container system, the master control system creates a pair of socket file descriptors (socket pair) and a container channel connecting the pair of file descriptors, and names the pair of file descriptors. And recording the file authority, the system identification allowed to be accessed, the maximum access number allowed and the identification of the descriptor of the file to be generated in the container channel creating request into the created container channel.

The master control system registers the container channel and its identifier and a pair of file descriptors, and a system identifier allowing access to the container channel in an NSS (domain Space Server) virtual device of the kernel. The master control system and the kernel correspondingly record the registered container channel, the identification and file descriptor pair thereof and the system identification allowing the container channel to be accessed.

The NSS of the kernel returns the identification of the container channel to the container system, along with the system identifications that allow access to the container channel. And respectively returning the identifier of the container channel and each system identifier allowing to access the container channel to the operating system corresponding to each system identifier.

The container system acquires one file descriptor in the file descriptor pair of the container channel from the NSS according to the acquired identifier of the container channel.

After receiving the request of the main control system for acquiring the container channel, the main control system finds out the identifier of the registered container channel and returns the identifier to the main control system.

After acquiring the identifier of the container channel, the master control system sends a file descriptor acquisition request carrying the identifier of the container channel to the NSS virtual device in the kernel.

And the NSS virtual equipment in the kernel searches out the other file descriptor in the file descriptor pair of the container channel from the registered container channel, the identifier of the container channel and the file descriptor pair according to the identifier of the container channel in the received file descriptor acquisition request, and returns the other file descriptor. Preferably, the NSS checks whether the security information such as the system identifier, the access number, and the like of the container system that sends the file descriptor acquisition request matches with the corresponding information recorded in the container channel; if the verification result is consistent, the identifier of the container channel in the request is obtained according to the received file descriptor, and the other file descriptor in the file descriptor pair of the container channel is found out from the registered container channel, the identifier of the container channel and the file descriptor pair, and is returned to the master control system.

Equivalently, one file descriptor in a pair of file descriptors connecting two ends of the container channel is returned to the container system, and the other file descriptor is returned to the process of the master control system.

And after the master control system acquires the other file descriptor returned by the kernel, the establishment of the container channel between the master control system and the container system is finished. The master control system may communicate with the container system that owns a file descriptor of the container channel to which the another file descriptor belongs, through the another file descriptor.

Preferably, for a pair of file descriptors, the master control system obtains the structure of the socket description file from the kernel according to one file descriptor returned to one container system, associates the structure with the one file descriptor, and records the structure in the container channel. The container channel is then registered into the NSS virtual device of the kernel.

After receiving a file descriptor acquisition request of a process of a main control system, NSS virtual equipment in a kernel queries an unused file descriptor in the process of the main control system, associates the unused file descriptor with a file structure of a socket description file stored in a container channel, and returns the associated file descriptor to the process of the main control system. At this time, the associated file descriptor is equivalent to another file descriptor in the file descriptors of the same container channel.

The terminal equipment in the embodiment of the invention is preset with a resource scheduling strategy. The resource scheduling policy defines respective resource occupation upper limits of the main control system, the foreground container system and the background container system. The resource in the embodiment of the present invention may include at least one of the following: processor resources, memory resources, non-volatile memory resources, data transfer bus bandwidth resources, and the like.

Preferably, in the embodiment of the present invention, a main control system, a container system in the foreground, and at least one other container system in the background may be configured in the terminal device.

For example, when there is one other container system in the background, the resource occupancy upper limits of the master system, the container system in the foreground, and the other container system in the background specified in the resource scheduling policy are 30%, 50%, and 20%, respectively.

When the number of the other container systems in the background is more than two, the resource scheduling policy specifies the resource occupation upper limit of each other container system in the background.

Preferably, the resource scheduling policy may first specify the resource occupancy upper limit of the master control system and the container system in the foreground from the total resources of the terminal device, and then determine the remaining resources outside the resource occupancy upper limit of the master control system and the container system in the foreground, and specify the resource occupancy upper limit of each of the other container systems in the background within the range of the remaining resources. And the resource proportion upper limit of each other container system in the background is not less than the minimum resource required by the other container systems to maintain running.

Further, the average resource required by the continuous operation of each other container system in the background is determined, and the resource proportion upper limit and the like of each other container system in the background are specified by taking the average resource as a unit from the residual resources. For example, when there are two other container systems in the background, the resource ratio upper limits of the master control system, the container system in the foreground, the container system a in the background, and the container system B in the background specified in the resource scheduling policy are 30%, 50%, 10%, and 10%, respectively.

Therefore, the resource scheduling strategy and the subsequent resource scheduling method of the multi-system based on the resource scheduling strategy in the embodiment of the invention are suitable for application scenes of a plurality of other container systems in the background.

For convenience of understanding, a method for scheduling resources of multiple systems according to an embodiment of the present invention is described below by taking a main control system, a first container system in a foreground, and a second container system in a background (i.e., one other container system in the background) as an example, where a flowchart of the method is shown in fig. 2a, and includes the following steps:

s201: when the master control system is started, according to the resource proportion upper limit of each of the master control system, the foreground container system and the background container system specified in the preset resource allocation strategy, a resource allocation directory including resource allocation subdirectories of the master control system, the first container system in the foreground and the second container system in the background is created.

And when the master control system is started, mounting the resource subsystem. For example, when the master control system starts up and needs to allocate processor resources of the master control system, the first container system and the second container system, the processor resource subsystem in the Cgroup of the kernel is acquired and mounted.

The main control system creates a resource allocation directory comprising resource allocation subdirectories of the main control system, a first container system in the foreground and a second container system in the background through the resource subsystem according to respective resource proportion upper limits of the main control system, the foreground container system and the background container system specified in a preset resource allocation strategy.

Preferably, the master control system creates a multi-system resource allocation directory through the resource subsystem.

The master control system creates a resource allocation subdirectory of the master control system under the name of the resource allocation directory through the resource subsystem; in the specified file of the resource allocation subdirectory of the main control system, the resource occupation ratio upper limit of the main control system and/or the numerical value related to the resource occupation ratio upper limit specified by the resource allocation strategy are set.

The main control system creates a resource allocation subdirectory of a first container system in the foreground through a resource subsystem; in a designated file of the resource allocation subdirectory of the first container system, a resource occupation upper limit of the foreground container system and/or a numerical value related to the resource occupation upper limit specified by the resource allocation policy are set.

The master control system creates a resource allocation subdirectory of a second container system in the background through the resource subsystem; and setting a resource proportion upper limit of the background container system and/or a numerical value related to the resource proportion upper limit specified by the resource allocation strategy in a specified file of the resource allocation subdirectory of the second container system.

For example, when the resource is specifically a processor resource, in a specified file cpu.shares in a processor resource allocation subdirectory of the master control system, a numerical value associated with a resource occupation ratio upper limit of the master control system specified by the resource allocation policy is set to be 614; in a designated file cpu.shares in a processor resource allocation subdirectory of a first container system, setting a value associated with a resource occupation ratio upper limit of a main control system specified by a resource allocation strategy as 1024; shares in a designated file cpu in a processor resource allocation subdirectory of the second container system, a numerical value associated with a resource occupation ratio upper limit of the main control system specified by the resource allocation policy is set as 410. The numerical value of the total processor resource of the terminal equipment of the embodiment of the invention is represented as the sum 2048 of 614, 1024 and 410; the processor resource allocation upper limits of the master control system, the first container system in the foreground, and the second container system in the background are about 614/2048-30%, 1024/2048-50%, and 410/2048-20%, respectively.

Preferably, the master control system stores the created resource allocation directory including the resource allocation subdirectories of the respective systems in the master control system or the kernel for the respective container systems to acquire.

Preferably, the master control system creates the front and background resource subdirectories of the master control system under the names of the resource allocation subdirectories thereof according to the respective resource occupation upper limits of the front and background processes of the master control system specified in the resource allocation strategy within the range of the resource occupation upper limit in the resource allocation subdirectories thereof.

The main control system distributes resources for the front and the back stage processes according to the front and the back stage resource subdirectories respectively.

Specifically, the master control system creates a foreground resource subdirectory of the master control system under the name of a resource allocation subdirectory of the master control system through a resource subsystem; in the range of the resource occupation upper limit in the resource allocation subdirectory, the resource occupation upper limit of the foreground process of the main control system specified in the resource allocation strategy and/or the numerical value related to the resource occupation upper limit are set in the specified file of the foreground resource subdirectory of the main control system.

The master control system creates a background resource subdirectory of the master control system under the name of the resource allocation subdirectory through the resource subsystem; in the range of the resource ratio upper limit in the resource allocation subdirectory, the resource ratio upper limit of the background process of the main control system and/or the numerical value related to the resource ratio upper limit specified in the resource allocation strategy are set in the specified file of the background resource subdirectory of the main control system.

The main control system distributes resources for the foreground process and the background process of the main control system according to the resource occupation upper limit in the foreground resource subdirectory and the background resource subdirectory and/or the numerical value associated with the resource occupation upper limit.

For example, the resource is specifically a processor resource, the upper limit of the processor resource occupation ratio of the front and the background processes of the main control system specified in the resource allocation policy is 60% and 40%, respectively, and the upper limit of the resource occupation ratio in the processor resource allocation subdirectory of the main control system is 30%; the upper limit of the processor resource ratio is set to 30% × 60% >, 18%, and 30% × 40% >, 12% respectively in the designated files of the front and back resource subdirectories of the main control system. The main control system distributes processor resources for a foreground process and a background process of the main control system according to the upper limit of the processor resource occupation ratio of 18 percent and 12 percent respectively.

S202: the master control system starts the first and second container systems.

Preferably, after the master control system starts the first container system, the resource occupation upper limits of the front and background processes of the background container system specified in the resource allocation policy are sent to the first container system through the container channel.

And after the master control system starts the second container system, sending the resource ratio upper limits of the front and background processes of the background container system specified in the resource allocation strategy to the second container system through the container channel.

S203: and the first container system and the second container system after starting acquire resources according to respective resource allocation subdirectories.

And when the first container system and the second container system are started, respectively acquiring the resource subsystems from the kernel, and mounting the acquired resource subsystems.

The first and second container systems obtain respective resource allocation subdirectories through the resource subsystem.

The first and second container systems respectively obtain resources according to their respective resource allocation subdirectories.

Preferably, the first and second container systems may use a variety of methods to allocate resources for their foreground and background processes.

A method for a container system to allocate resources for a front and a back stage process thereof comprises the following steps: after the first container system receives the resource occupation upper limits of the front and the background processes of the background container system specified in the resource allocation strategy sent by the master control system through the container channel, in the range of the resource occupation upper limits in the resource allocation subdirectory of the first container system, the front and the background resource subdirectories of the first container system are respectively created under the names of the resource allocation subdirectories according to the received resource occupation upper limits of the front and the background processes of the background container system.

And the first container system allocates resources for the front and the background processes according to the front and the background resource subdirectories.

Specifically, the first container system creates a foreground resource subdirectory of the first container system under the name of a resource allocation subdirectory of the first container system through a resource subsystem; in the range of the resource occupation upper limit in the resource allocation subdirectory, the resource occupation upper limit of the foreground process of the foreground container system specified in the resource allocation strategy and/or the numerical value related to the resource occupation upper limit are set in the specified file of the foreground resource subdirectory of the first container system.

The first container system creates a background resource subdirectory of the first container system under the name of a resource allocation subdirectory of the first container system through a resource subsystem; in the range of the resource occupation upper limit in the resource allocation subdirectory, the resource occupation upper limit of the background process of the foreground container system specified in the resource allocation strategy and/or the numerical value related to the resource occupation upper limit are set in the specified file of the background resource subdirectory of the first container system.

The first container system distributes resources for the foreground process and the background process of the first container system according to the resource occupation upper limit in the foreground resource subdirectory and the background resource subdirectory and/or the numerical value associated with the resource occupation upper limit.

For example, the resource is specifically a processor resource, the respective processor resource occupation upper limits of the front and back processes of the front container system specified in the resource allocation policy are 70% and 30%, respectively, and the resource occupation upper limit in the processor resource allocation subdirectory of the front container system is 50%; then, in the designated files of the front and back-end resource subdirectories of the first container system, the upper limit of the processor resource ratio is set to 50% × 70% >, 35%, 50% × 30% >, 15%, respectively. The first container system allocates processor resources for the foreground process and the background process of the first container system according to the processor resource occupation upper limits of 35% and 15% respectively.

Similarly, the second container system may allocate resources for the foreground and background processes of the second container system according to the method.

For example, the resource is specifically a processor resource, the respective upper limits of the processor resource occupation ratios of the front and the background processes of the background container system specified in the resource allocation policy are respectively 80% and 20%, and the upper limit of the resource occupation ratio in the processor resource allocation subdirectory of the background container system is 20%; then, in the designated files of the front and back-end resource subdirectories of the second container system, the upper limit of the processor resource ratio is set to 20% × 80% >, 16%, 20% × 20% >, 4%, respectively. And the second container system allocates processor resources for the foreground process and the background process of the second container system according to the 16 percent and 4 percent of processor resource occupation ratio upper limit respectively.

In addition, it should be noted that, in this step, the resource occupation rate upper limits of the foreground process and the background process of the first container system in the foreground are higher than the resource occupation rate upper limits of the foreground process and the background process of the second container system in the background. However, this is not essential. Those skilled in the art can reasonably determine the resource ratio upper limit of each system and its foreground and background processes according to historical data, empirical data, experimental data, and/or actual conditions, etc., so as to meet various needs of users.

Another method for allocating resources to the front and the back processes by the container system comprises the following steps: the first container system respectively creates front and background resource subdirectories of the first container system under the name of a resource allocation subdirectory thereof according to respective resource proportion upper limits of the front and background processes preset therein; the first container system allocates resources for the front and background processes according to the front and background resource subdirectories respectively.

Specifically, the first container system creates a foreground resource subdirectory of the first container system under the name of a resource allocation subdirectory of the first container system through a resource subsystem; in the range of the resource occupation upper limit in the resource allocation subdirectory, the resource occupation upper limit of the foreground process preset in the first container system and/or the numerical value associated with the resource occupation upper limit are set in the specified file of the foreground resource subdirectory of the first container system.

The first container system creates a background resource subdirectory of the first container system under the name of a resource allocation subdirectory of the first container system through a resource subsystem; in the range of the resource ratio upper limit in the resource allocation subdirectory, the resource ratio upper limit of the background process preset in the first container system and/or the numerical value associated with the resource ratio upper limit are set in the designated file of the background resource subdirectory of the first container system.

Similarly, the second container system respectively creates front and background resource subdirectories of the second container system under the names of the resource allocation subdirectories according to the respective resource proportion upper limits of the front and background processes preset in the second container system; and the second container system distributes resources for the front and the background processes according to the front and the background resource subdirectories respectively.

It is easy to understand that the method for allocating resources to the foreground and background processes by the container system is more suitable for application scenarios in which the container system does not have (preset) the resource occupation upper limit of the foreground and background processes, or has higher security requirements although the container system has the resource occupation upper limit of the foreground and background processes; for example, the resource occupation upper limit of the foreground and background processes of the container system may be tampered with by a malicious program, and a file where the resource occupation upper limit of the foreground and background processes of the container system is attached by the malicious program.

In practical operation, for the above steps S201 and S202, step S201 may be executed first and then step S202 may be executed, step S202 may be executed first and then step S201 may be executed, or step S201 and step S202 may be executed simultaneously.

In fact, through the flow of the above steps S201 to S203, a schematic diagram of an example of the resource allocation directory of multiple systems in the terminal device in the embodiment of the present invention is shown in fig. 3, and the resource allocation directory is in a tree structure, and is located at a root node, and has resource allocation subdirectories of the master control system, the first container system in the foreground, and the second container system in the background; a foreground resource subdirectory and a background resource subdirectory of the master control system are arranged under the resource allocation subdirectory name of the master control system; a foreground resource subdirectory and a background resource subdirectory of the first system are arranged under the name of the resource allocation subdirectory of the first system; the resource allocation subdirectory of the second system is provided with a foreground resource subdirectory and a background resource subdirectory of the second system.

The other method for distributing resources for the foreground and background processes by the container system is more suitable for application scenarios in which the container system has the resource occupation upper limit of the foreground and background processes and has lower security requirements.

In fact, an embodiment of the present invention further provides a method for scheduling resources of multiple systems suitable for foreground and background switching of a container system, where a flowchart of the method is shown in fig. 2b, and on the basis of the above steps S201 to S203, the following steps are added:

s204: and the master control system updates the resource allocation subdirectories of the first container system and the second container system which are respectively switched to the background and the foreground according to the resource allocation strategy.

And after the main control system detects that the first container system and the second container system are switched between the front stage and the back stage, updating the resource occupation upper limits in the resource allocation subdirectories of the first container system and the second container system respectively switched to the back stage and the front stage according to the respective resource occupation upper limits of the back stage container system and the front stage container system specified in the resource allocation strategy.

Specifically, after detecting that the first container system is switched to the background and the second container system is switched to the foreground, the main control system updates the resource proportion upper limit and/or the numerical value associated with the resource proportion upper limit in the specified file of the resource allocation subdirectory of the first container system to the resource proportion upper limit and/or the numerical value associated with the resource proportion upper limit of the background container system specified in the resource allocation strategy; and updating the resource occupation upper limit and/or the numerical value associated with the resource occupation upper limit in the specified file of the resource allocation subdirectory of the second container system into the resource occupation upper limit and/or the numerical value associated with the resource occupation upper limit of the foreground container system specified in the resource allocation strategy.

And respectively switching to the first container system and the second container system of the background and the foreground to acquire resources according to the updated resource allocation subdirectories.

Preferably, the main control system updates the resource proportion upper limit and/or the numerical value associated with the resource proportion upper limit in the specified file of the resource allocation subdirectory of the first container system switched to the background to the resource proportion upper limit and/or the numerical value associated with the resource proportion upper limit of the background container system specified by the resource allocation policy through the resource subsystem.

And the main control system updates the resource occupation upper limit and/or the numerical value associated with the resource occupation upper limit in the specified file of the resource allocation subdirectory of the second container system switched to the foreground into the resource occupation upper limit and/or the numerical value associated with the resource occupation upper limit of the foreground container system specified by the resource allocation strategy through the resource subsystem.

And the first container system switched to the background allocates resources for the front and background processes according to the updated front and background resource subdirectories.

Further, the first container system switched to the background updates the resource occupation upper limit of the foreground process in the specified file of the foreground resource subdirectory of the first container system and/or the numerical value associated with the resource occupation upper limit to the resource occupation upper limit of the foreground process of the background container system and/or the numerical value associated with the resource occupation upper limit specified in the resource allocation strategy in the range of the resource occupation upper limit in the resource allocation subdirectory updated by the resource subsystem.

And the first container system switched to the background updates the resource occupation upper limit of the background process in the specified file of the background resource subdirectory of the first container system and/or the numerical value associated with the resource occupation upper limit into the resource occupation upper limit of the background process of the background container system and/or the numerical value associated with the resource occupation upper limit specified in the resource allocation strategy in the range of the resource occupation upper limit in the resource allocation subdirectory updated by the first container system through the resource subsystem.

And the first container system switched to the background allocates resources for the foreground process and the background process of the first container system switched to the background according to the updated resource occupation upper limit in the foreground resource subdirectory and the background resource subdirectory and/or the value associated with the resource occupation upper limit.

For example, the resource is specifically a processor resource, the respective upper limits of the processor resource occupation ratios of the front and the background processes of the background container system specified in the resource allocation policy are respectively 80% and 20%, and the upper limit of the resource occupation ratio in the processor resource allocation subdirectory of the background container system is 20%; the processor resource in the designated file of the updated front and background resource subdirectories of the first container system switched to the background is updated to 20% × 80% ═ 16%, and 20% × 20% ═ 4%, respectively. And the first container system switched to the background allocates processor resources for the foreground process and the background process of the first container system switched to the background according to the processor resource occupation upper limits of 16% and 4% respectively.

Similarly, the resource allocation subdirectory, the foreground resource subdirectory, and the resource proportion upper limit and/or the resource proportion upper limit associated numerical value in the background resource subdirectory of the second container system switched to the foreground can be updated.

In real time, the resource proportion upper limit of the first container system and the foreground and background processes switched to the background is consistent with the resource proportion upper limit of the second container system and the foreground and background processes when the second container system and the foreground and background processes are in the background; the resource ratio upper limit of the second container system and the foreground and background processes switched to the foreground is consistent with the resource ratio upper limit of the first container system and the foreground and background processes when the first container system and the foreground and background processes are in the foreground.
