Description
Technical Field
The invention relates to the field of communication, in particular to a terminal memory recovery processing method and device.
Background
The memory is a key resource of the system, and when the memory is in shortage, the jamming, the slow response and running speed, the error reporting of task running and even the system restart and crash can occur. Therefore, memory management is one of core technologies of the system, and plays a key role in improving the user experience of the system and the stability of system operation. Multisystem refers to running multiple application systems on the basis of one operating system kernel. With the improvement of the requirements on the security of the mobile phone, multiple systems are increasingly applied as important technical schemes for improving the security of the mobile phone. However, the memory occupation of multiple systems is greatly increased, so that the memory needs to be better managed aiming at the characteristics of the multiple systems, otherwise, the multiple systems are more prone to various problems caused by the memory shortage than a single system in the using process.
The memory management of multiple systems is based on the memory management of a single system, and is adjusted and optimized aiming at the characteristics of multiple systems. The main methods are as follows: 1) based on the resource control method, the amount of memory that each system can use is limited by using a resource control mechanism (e.g., cgroup of linux) provided by an operating system kernel, so that a certain system is prevented from occupying too much memory to enable other systems to not operate normally. The method has the disadvantages that resources are wasted, when one system is loaded to a load exceeding the memory quota allowed to be used, the other system can not take out the free memory for the system with the current load even if the memory occupied by the other system is very low; 2) the user mode program (such as an Android framework layer) adjusts the usage amount of the memory according to the current condition of the system, for example, when the user mode program finds that the user mode program is a background system, more memory is released more actively for other systems to use. The method for managing the memory based on the user mode program has limited memory releasing effect and side effect, and the memory releasing affects the performance and the function of the system at the cost of stopping the process or a certain module function in the system. 3) The method can ensure that the power of each system which is already running is not influenced. However, the existing management method looks like the memory used by all the systems, and does not consider the different influences of the same management operation on the systems. For example, when a memory page is swapped out, selecting to swap out a memory page used in a background system and a memory page used in a foreground system (with which a user may interact) has an impact on user experience, and if a memory page used in a foreground system is swapped out, the user is more likely to experience performance degradation caused by the selected memory page.
Aiming at the problem that the same memory recovery mechanism in multiple systems does not consider different influences of the same management operation on the systems in the related technology, a solution is not provided.

With the mobile phone as a portable information and data processing center, the mobile phone has various important and sensitive information and programs, such as bank account numbers and passwords, contact information, working application programs, and the like, and the mobile phone is urgently required to have higher security so as to protect the security of the operation and data of the programs. The safety can be effectively achieved by adopting a double system based on the container, and the system used in daily life runs in one container, has good openness and use convenience, and meets various use conveniences in life; and a system requiring high security, such as a system used in a working environment, is operated in another container, and programs and data of the system are controlled by strict security measures. When the two systems run, complete safety isolation is carried out by depending on a safety mechanism provided by an operating system kernel, and one system cannot access and sniff any information and running state of the other system, so that the safety information is ensured not to be leaked. Meanwhile, because the resource management is carried out based on the same operating system kernel, the two systems can share hardware resources (CPU, internal memory, IO equipment and the like), the performance is ensured, the hardware cost is reduced, and the carrying and use convenience is improved.
The following further describes the embodiments of the present invention by taking a dual system as an example.
This embodiment provides a memory management method for dual systems, and fig. 3 is a flowchart of a memory recovery method according to an embodiment of the present invention, as shown in fig. 3, the method flow is as follows:
step S302, monitoring and finding out the shortage of the memory, and triggering the memory recovery operation;
step S304, obtaining a memory page set R1 which can be recycled by using the recorded memory use information and according to an approximate LRU algorithm;
step S306, for each memory page in R1, acquiring all processes using the memory page, and obtaining which application system the memory page belongs to according to which application system the processes belong to;
step S308, selecting a memory page set R2 needing to be recovered from R1 in proportion according to a recovery proportion value preset by each application system;
in step S310, a memory recycle operation is performed on the inner page set R2, and the memory pages in R2 are released to the free memory of the system.
Through the steps, on the basis of the existing memory management method based on the approximate LRU algorithm in the kernel of the operating system, and in addition, the influence of the management operation on the system to which the managed memory belongs is considered, the management operation which does not influence the performance of the user experience (namely, the performance of the foreground system) is preferentially selected, so that under the condition of heavy load of the system memory, the functions of all the systems can still be ensured not to be influenced, and meanwhile, the influence on the user experience is not influenced or reduced.
Optionally, the memory reclamation specifically includes the following steps:
step 1, monitoring and finding that an idle memory is lower than a threshold value, and starting memory recovery operation;
step 2, obtaining a memory page set R1 which can be recycled by using the recorded memory use information according to an approximate LRU algorithm; the so-called LRU (least recently used) algorithm is to find out the memory page set which has not been accessed for a period of time recently;
step 3, for each memory page in R1, each process using the memory page is recorded, and in the corresponding process information, which application system the process belongs to is recorded, so that which application system the memory page belongs to is obtained;
step 4, selecting a memory page set R2 needing to be recovered from R1 in proportion according to a recovery proportion value preset by each application system; assuming A, B two application systems, setting the recovery ratio of A to be 1/3 and the recovery ratio of B to be 2/3, if N pages are selected for recovery, wherein the number of the pages belonging to the application system A is N/3, and the number of the pages belonging to the application system B is 2N/3;
and step 5, performing memory recycling operation on the inner page set R2, releasing the memory pages in the R2 to the free memory of the system, writing the page contents in the R2 back to a file or a swap partition, and then putting the pages in the R2 into the free memory pool of the system, wherein the pages can be allocated to other memory users for use.
The specific implementation method for selecting the recycled memory page according to the recycling ratio value is as follows:
assuming A, B two application systems, setting the recovery ratio of A to 1/3 and B to 2/3, 6 pages need to be selected for recovery, the first R1 case is as follows (MX indicates the memory page number, the parenthesis indicates which system the memory page belongs to, and the ranking indicates the priority ranking of recovery, i.e. the recovery ranked first is better than the recovery ranked later):
M1(A)，M2(A)，M3(B)，M4(A)，M5(A)，M6(B)，M7(B)，M8(B)，M9(A)，M10(B)，M11(A)，M12(B)，M13(A)，M14(B)，M15(A)，M16(A)，M17(A)，M18(B)
then there should be 2 pages belonging to a and 4 pages belonging to B, and then the 2 pages belonging to a and the 4 pages belonging to B are selected in order as follows: m1(a), M2(a), M3(B), M6(B), M7(B), M8 (B).
In the algorithm, the order of selecting the R2 from the page set in R1 may be unordered (random) or in other ordering manners.
When the recycle proportion of the application system is set, a more obvious rule is that the recycle proportion of the foreground application system is set to be lower, so that the memory page of the foreground system is ensured to be remained in the system as much as possible.
