Container technique carries out isolation of system.
Embodiment one
The embodiment of the present application provides a kind of method of memory management, as shown in Figure 1, this method includes：
Step S101, when detecting memory headroom application request, the application program said system for sending the request is determined.
The application program is determined when the operation of a certain application program needs committed memory space for the embodiment of the present application
Affiliated operating system.
For example, being equipped with application program 1 and application program 2 in operating system 1, it is equipped in operating system 2 using journey
Sequence 3, application program 4 and application program 5 determine the application program 1 when the operation of application program 1 needs committed memory space
Corresponding operating system is operating system 1.
Step S102, based on the application program said system for sending the request, the corresponding memory headroom of the system is determined.
For the embodiment of the present application, each operating system may correspond to different memory headrooms；Or each operating system
Shared drive determines each operating system currently corresponding memory headroom according to preset rules.
For example, preset rules can be to determine each operating system based on each piece of memory last time occupied operating system
Current corresponding memory headroom.
It step S103, is the application assigned memory from the corresponding memory headroom of the system determined.
For the embodiment of the present application, based on the application program said system pair for sending the request determined in step S102
In the memory headroom answered, the memory headroom of size is preset for the application assigned；Or based on determining in step S102
It sends in the corresponding memory headroom of application program said system of the request, and applies occupying according in memory headroom application request
The size of memory headroom is suitble to the memory headroom of size for the application assigned.
The embodiment of the present application provides a kind of method of memory management, and from shared drive is directly in the prior art application
Program storage allocation is compared, and in the embodiment of the present application when detecting memory headroom application request, is determined and is sent answering for the request
With program said system, it is then based on the application program said system for sending the request, determines the corresponding memory headroom of the system,
It and is the application assigned memory, i.e., each system in the embodiment of the present application from the corresponding memory headroom of the system determined
It unites and corresponds to a memory headroom, when for application assigned memory headroom, from the corresponding memory of application program said system
It is the application assigned memory in space, so as to avoid by the leaking data in a system to other systems, in turn
It can be improved and internally deposit the safety being managed.
Embodiment two
The alternatively possible implementation of the embodiment of the present invention further includes two institute of embodiment on the basis of example 1
The operation shown, wherein
Step S102 includes step S1021, and step S103 includes step S1031, wherein
Step S1021, based on the application program said system for sending the request, the affiliated memory pool of the system is determined.
Further include before step S1021：Corresponding memory pool is distributed for each system.
For the embodiment of the present application, by be arranged in terminal device memory pool according to operating system in terminal device
Number is split, so that the corresponding memory pool of each operating system in terminal device.
For example, currently operation has 2 operating systems, operating system 1 and operating system 2 in terminal device, then by terminal
An original memory pool is split as 2 in equipment, and memory pool 1 and memory pool 2, operating system 1 can correspond to memory pool 1,
Operating system 2 can correspond to memory pool 2.
For the embodiment of the present application, the size of the memory headroom of each memory pool after dynamic setting fractionation.In the application
In embodiment, the size of the memory headroom of each memory pool after fractionation can also be set by user setting by terminal device
It sets.In the embodiment of the present application without limitation.
For example, the memory headroom for the memory pool that original multisystem is shared can be 4G, then the memory pool is split as two
A memory pool, the size of the corresponding memory headroom of memory pool 1 can be 1G, and the size of the corresponding memory headroom of memory pool 2 can be with
For 3G.
For the embodiment of the present application, the memory headroom of specified size is distributed by malloc ().
It step S1031, is the application assigned memory from the affiliated memory pool of the system.
For example, the application program said system of application memory headroom is system 2, then it is the application program from memory pool 2
Storage allocation.
For the embodiment of the present application, by determining belonging to the system based on the application program said system for sending the request
Memory pool, and be the application assigned memory from the affiliated memory pool of the system, i.e., each corresponding memory of operating system
Pond, be application assigned memory when, distributed from the corresponding memory pool of the operating system, thus avoid by other systems it
Before account for used memory headroom and distribute to application program in the system, cause system data to leak to another by a system
System, and then can be further improved the safety of memory management.
Embodiment three
The alternatively possible implementation of the embodiment of the present invention further includes three institute of embodiment on the basis of example 2
The operation shown, wherein
Further include after step S1021：It is corresponding from other systems when memory headroom deficiency in the affiliated memory pool of the system
Memory pool in determine the memory headroom to be allocated to the application program；The memory headroom to be allocated to the application program is emptied,
And the memory headroom after emptying is distributed into the application program.
For the embodiment of the present application, when a certain application program calls memory, and the application program said system pair
It is the application assigned memory from the corresponding memory pool of other systems, but work as when the memory headroom deficiency for the memory pool answered
Before the memory headroom in the corresponding memory pool of the other systems distributes to the application program, it is to be allocated interior to need to empty this
The dirty data in space is deposited, the memory headroom for emptying dirty data is then distributed into the application program.
For example, when memory, and the corresponding memory pool 1 of operating system 1 belonging to the application program 1 are called in the application of application program 1
Low memory when, from memory pool 2 be 1 storage allocation of application program, before storage allocation, empty in memory pool 2 to
Dirty data into the memory headroom of application program 1 is distributed, the memory headroom after dirty data then will be emptied and distributes to the application
Program 1.
It, can be from other operations when the memory headroom deficiency of the corresponding memory pool of certain system for the embodiment of the present application
It is the application assigned memory in the corresponding memory pool of system, so that application program normal operation, avoids application program
The case where deferred run；Furthermore after memory headroom to be allocated is emptied dirty data, it is redistributed to the application program, it can
It avoids the leaking data in a system to another system, so as to avoid system data from leaking, and then can be into one
Improve the safety of memory management in step ground.
