Description

Method for recovering internal storage and device, terminal device and computer readable storage medium

Technical field

The present invention relates to the control field of electronic equipment, specifically realizing Memory recycle on the terminal device in one kind Method and the device for realizing this method, further relate to a kind of terminal device for realizing the above method and computer-readable storage Medium.

Background technology

The terminal devices such as smart mobile phone, tablet computer become the most frequently used electronic equipment in people's daily life, people Like various application programs are installed on intelligent electronic device, and on the terminal device simultaneously run largely apply journey Sequence.And in the operating system of terminal device, in order to accelerate to be written and read disk the speed of operation, it will usually by a large amount of data Caching is in memory.Process needs committed memory of filing an application and start before memory is used, after memory has been used again in time Recycle memory.Since user is during using terminal is applied, application is often frequently replaced, in order to reduce the waiting of user Duration, operating system would generally be transferred to backstage application process retain its occupancy memory.But when background application is excessive, It, can be because Memory Allocation deficiency causes operating system exception occur when memory is largely occupied and cannot recycled.

In order to avoid the system exception caused by Memory Allocation deficiency, operating system introduces the reclaim mechanism to memory. For example, when low memory, system can close some background process to recycle the memory of its occupancy.But when user needs to make During application program corresponding with these processes, these processes needs are completely reloaded, and time-consuming, reduce user's body It tests.Therefore, the prior art proposes the method that Memory recycle is carried out in the case of not closing process.Chained list is at least used in the recent period LRU arranges Physical Page according to recent service condition, and when low memory, system can be preferentially to therein Physical Page in the two chained lists of INACTIVE_ANON and INACTIVE_FILE is recycled.ANON represents anonymous mapping, does not have There is backing storage, FILE represents File Mapping, and INACTIVE is represented in inactive state.When process is needed using recycling During content on Physical Page, as long as loading corresponding contents from disk, reduce and take.But the application of front stage operation into Journey or the high application process of the priority of running background, the Physical Page occupied may also be in INACTIVE_ANON and In the two chained lists of INACTIVE_FILE, the Physical Page in the two chained lists, which is recycled, may influence this two classes application Normal operation, reduce user experience.

In order to ensure the normal operation of the high application process of the priority of foreground application process and running background, the prior art The method for proposing to carry out Memory recycle for process obtains the Physical Page of target process, is searched later not by target process first The target physical page that uses simultaneously recycles target physical page.But in the existing method that Memory recycle is carried out to process, time For the target physical page of receipts only for the target physical page not used by target process, target physical page is mainly that target process exists Physical Page in the two chained lists of INACTIVE_ANON and INACTIVE_FILE, that is, the Physical Page of inactive state, this The Memory recycle efficiency of kind method is very low.

If in addition, carrying out Memory recycle operation to the process of application program that user is commonly used, can cause to apply journey Often process is reloaded in loading to sequence, is caused application program operation slow, is influenced user experience.

Invention content

The first object of the present invention is to provide a kind of different type application program of distinguishing using different Memory recycle modes Method for recovering internal storage.

The second object of the present invention, which is to provide, a kind of to be avoided performing the application program that frequently uses Memory recycle operation Memory recycle device.

The third object of the present invention is to provide a kind of terminal device that can realize above-mentioned method for recovering internal storage.

The fourth object of the present invention, which is to provide when one kind is read out by the processor and performs, can realize above-mentioned Memory recycle side The computer readable storage medium of method.

In order to realize the first above-mentioned purpose, method for recovering internal storage provided by the invention is applied to terminal device, this method Including obtaining the destination application being currently running, judge whether destination application is Memory recycle protection application program；Such as It is Memory recycle protection application program to determine destination application, destination application is performed in predetermined time period few It is operated in the Memory recycle of the first preset times；It is not Memory recycle protection application program such as to determine destination application, pre- If the Memory recycle operation for being no less than the second preset times is performed in time span to destination application or closing target should Use program；Wherein, the first preset times are less than or equal to the second preset times.

By said program as it can be seen that for different application programs using different ways of recycling, such as Memory recycle Application program is protected, then by the way of less recovered frequency, for not being that Memory recycle protects application program, such as frequency of use Relatively low application program, then may be used the operation of multiple Memory recycle by discharge it is more in a manner of to discharge more memories.

One Preferable scheme is that, determine destination application be Memory recycle protection application program include：Obtain target The running frequency of application program determines that the running frequency of destination application is higher than preset operating frequency；Alternatively, determine that target should It is the application program in default Memory recycle protection list with program；Alternatively, determine destination application answering for preset kind Use program.

It can be seen that for the application program in the higher application program of running frequency, default Memory recycle protection list And the application program of preset kind, Memory recycle is carried out in a manner that recovered frequency is less, avoids these application program quilts Frequently execute the speed of service that Memory recycle operates and influences application program.

Further embodiment is to determine that destination application is not after Memory recycle protects application program, and obtaining target should The memory value occupied with program, judges whether the memory value that destination application occupies is more than default memory value, if so, then pre- If performing the Memory recycle operation for being no less than the second preset times in time span to destination application, otherwise, target is closed Application program.

As it can be seen that for the less application program of committed memory value, the operation that Memory recycle is performed to application program is not used, But directly by closing application program, so as to recycle more memories.

Preferably, the second preset times are more than secondary；Destination application is performed in predetermined time period many Include in the Memory recycle operation of the second preset times：After performing a Memory recycle operation, after the first interval time, hold Memory recycle operates row next time.

Preferably, the Memory recycle for being not more than the first preset times is performed to destination application in predetermined time period Operation includes：The Memory recycle more than secondary is performed to destination application in predetermined time period to operate, also, perform one After secondary Memory recycle operation, after the second interval time, perform Memory recycle next time and operate；Second interval time was more than the One interval time.

It can be seen that for the application program of Memory recycle protection, multiple Memory recycle is performed in predetermined time period The time interval of operation is more than the time interval that non-Memory recycle protection application program performs Memory recycle operation twice, so as to subtract Small Memory recycle preserves the number of the Memory recycle operation of application program.

Further embodiment is to perform Memory recycle operation to destination application to include：Obtain destination application just In the target process of operation, and obtain the corresponding target physical page of target process；Read the value of the liveness of target physical page, mesh Mark active level of the liveness of Physical Page for marking target reason page, the value and target physical of the liveness of target physical page The active level positive correlation of page；If the value of the liveness of target physical page is higher than recycling standard, and the value of liveness is higher than recycling The Physical Page of standard is in active state, then reduces the liveness of target physical page；Read again the liveness of target physical page Value；If the value of the liveness of target physical page is not higher than recycling standard, target physical page is recycled.

By said program as it can be seen that after the corresponding target physical page of target process is obtained, if target physical page enlivens The value of degree is higher than recycling standard, can reduce the liveness of target physical page, and be not higher than back in the liveness of target physical page During receipts standard, target physical page is recycled.In this way, even if target physical page is the Physical Page of active state, the present invention Have an opportunity to recycle target physical page, compared with the prior art, the present invention greatly expands the object of Memory recycle, improves Memory recycle efficiency.

Further, reduce target physical page liveness after, read target physical page liveness value it Before, open timer；When the duration of timer record reaches preset duration, the value of the liveness of target physical page is read in triggering The step of.

Further, before opening timer, preset duration, preset duration and EMS memory occupation are set according to memory usage Rate is negatively correlated；Alternatively, the priority positive of preset duration, preset duration and target process is set according to the priority of target process It closes.

Further, the selectable value of liveness includes at least the first value, second value and third value, and the first value is not higher than recycling Standard, second value are less than third value, and higher than recycling standard.

Further, the liveness for reducing target physical page includes：It, will when the liveness of target physical page is third value The liveness of target physical page is set as second value；When the liveness of target physical page is second value, by target physical page Liveness is set as the first value.

Further, the liveness for reducing target physical page includes：When target physical page is anonymous page, according to the first width Degree reduces the liveness of target physical page；When target physical page is file page, according to the second amplitude reduction target physical page Liveness；First amplitude is less than the second amplitude.

To realize the second above-mentioned purpose, Memory recycle device provided by the invention is applied to terminal device, the device packet Acquisition module is included, for obtaining the destination application being currently running；Judgment module, for judge destination application whether be Memory recycle protects application program；Memory recycle module, for determining that destination application is that journey is applied in Memory recycle protection During sequence, the Memory recycle operation for being not more than the first preset times is performed to destination application in predetermined time period；And Determine destination application be not Memory recycle protection application program when, in predetermined time period to destination application perform Destination application is closed in the Memory recycle operation of no less than the second preset times；Wherein, the first preset times are less than the Two preset times.

Preferable scheme is that judgment module is specifically used for：The running frequency of destination application is obtained, judges intended application Whether the running frequency of program is higher than preset operating frequency；Alternatively, judging whether destination application is that default Memory recycle is protected Protect the application program in list；Alternatively, judge destination application whether be preset kind application program.

Further, Memory recycle module includes：Acquisition module, for obtaining the corresponding target physical page of target process； First read module, for reading the value of the liveness of target physical page, the liveness of target physical page is used for marking target Manage the active level of page, the value of the liveness of target physical page and the active level positive correlation of target physical page；Module is reduced, is used When the value of the liveness when target physical page is higher than recycling standard, the liveness of target physical page is reduced, the value of liveness is high It is in active state in the Physical Page of recycling standard；Second read module, in the work for reducing module reduction target physical page The value of jerk and then the secondary liveness for reading target physical page；Recycling module, for working as the value of the liveness of target physical page During not higher than recycling standard, target physical page is recycled.

Specific embodiment

Method for recovering internal storage of the present invention is applied on the terminal devices such as smart mobile phone or tablet computer, for reality The recycling of the occupied memory of existing application program.The Memory recycle device operation of this hair invention on the terminal device, and is used for Realize above-mentioned method for recovering internal storage.

Since user is during application program is used, often application program used in frequent replacement, such as profit During video being watched with video jukebox software, it may be necessary to chat application frequently are switched to foreground, in order to reduce use The waiting time at family, operating system would generally be transferred to backstage application process retain its occupancy memory.But when backstage is transported Capable application program is excessive, can be because Memory Allocation deficiency is led when the memory of terminal device is largely occupied and cannot discharged Operating system is caused to occur abnormal.

Terminal device can carry out Memory recycle by closing application program, can also by not closing application program, But the mode that Memory recycle is carried out to the process of application program carries out Memory recycle.However, some application program is to use The application program that family is commonly used if frequently performing Memory recycle operation to this certain applications program, leads to user's weight Newly in the front stage operation application program, which needs to reload process, and the operation for leading to application program is slow, shadow Ring user experience.Therefore, it is necessary to the Memory recycle mode of differentiation is used to different types of application program.

It is provided by the invention for different types of application program using differentiation method for recovering internal storage as shown in Figure 1, Include the following steps：

Step S101 obtains the application program being currently running.

When the current free memory amount of terminal device is relatively low or terminal device operation is slow, operating system can be actively Send out Memory recycle operation instruction, that is, for one or more application program perform Memory recycle, at this time, it may be necessary to Obtain the destination application being currently running.For example, the application list information being currently running by task manager acquisition, The application program being currently running is obtained from the list information.It should be noted that the application program acquired in step S101 can To be the application program of front stage operation or be placed in the application program of running background.

Step S102 judges whether destination application is Memory recycle protection application program, if so, being transferred to step Otherwise S103, is transferred to step S104.

After destination application is obtained, the type of destination application is judged, that is, judge intended application Whether program is Memory recycle protection application program.In the present embodiment, Memory recycle protection application program be need to perform it is less The number of Memory recycle operation or the application program for not performing Memory recycle operation, specifically, Memory recycle protection is using journey Sequence can be the application program of the more favorite application program of user, the application program in default white list or preset kind.

A kind of situation of Memory recycle protection application program is the higher application program of user's favorable rating, for example, can be with Favorable rating of the user to a certain application program is determined by Meizu OneMind application programs, if user's favorable rating is higher than Preset threshold value, then it represents that user likes the application program very much, then the application program is Memory recycle protection application program.

A kind of mode for determining user's favorable rating is to calculate the running frequency of destination application, in the present embodiment, mesh Mark application program running frequency be in the unit interval destination application run number, destination application in the unit interval Number of run is more, then running frequency is higher, opposite, destination application number of run is fewer in the unit interval, then runs Frequency is lower.Specifically, number of run can be the number that destination application is placed in front stage operation, that is, intended application journey Sequence calculates the number of a destination application front stage operation from when being transferred to front stage operation from the background.

Certainly, running frequency can also be that destination application performs time for receiving user operation instruction in the unit interval Number for example, when destination application is run, receives the number of user's clicking operation page, the number for receiving acoustic control instruction etc., single The user operation instruction number received in the time of position is more, and the running frequency of destination application is higher, opposite, the unit interval The user operation instruction number of interior reception is fewer, and the running frequency of destination application is lower.

The third mode for determining the running frequency of destination application is in the unit of account time before destination application The time span of platform operation, the time span of destination application front stage operation is longer in the unit interval, then destination application Running frequency it is higher, opposite, unit interval destination application front stage operation time span is shorter, destination application Running frequency is lower.

When the running frequency of destination application is higher than preset running frequency, it is memory to determine the destination application Recycling protection application program, if the running frequency of destination application is less than the preset running frequency, it is determined that the mesh Mark application program is not Memory recycle protection application program.

In addition, Memory recycle protection application program can also be the application program in default Memory recycle protection list, example Such as, white list is pre-set, which is exactly the list of Memory recycle protection application program, if destination application is interior It is stored back to the application program received in protection the application list, it is determined that destination application is Memory recycle protection application program.

In addition, Memory recycle protection application program can also be the application program of preset kind, for example, the application of game class Program.When depositing reclaimer operation inside due to the application program of game class can not effective releasing memory, can be as far as possible Few application program to game class performs Memory recycle operation, that is, the application program of game class is determined as preset kind Application program.Certainly, the application program of preset kind can also include the application program of instant messaging class, web page browsing class is answered With program etc..

In step s 102, if it is determined that the running frequency of destination application is higher than preset running frequency or really The application program that sets the goal is application program in default Memory recycle protection list or determining destination application is default class The application program of type, then it is Memory recycle protection application program that can determine destination application.

Step S103 performs destination application in predetermined time period and is stored back in not more than the first preset times It brings drill to an end work.

If it is determined that destination application is Memory recycle protection application program, then it represents that destination application should not be by The Memory recycle operation of more number is performed, therefore, it is necessary to limit the number that destination application is performed Memory recycle and operated. For example, predetermined time period is three minutes, the first preset times are application programs that is primary, then being protected for Memory recycle, Primary Memory recycle operation can only be at most performed in three minutes, does not perform Memory recycle operation even.It is appreciated that in the limit In the case of, the first preset times are zero degrees, that is, do not perform Memory recycle operation to Memory recycle protection application program.

In other words, if it is determined that destination application is Memory recycle protection application program, then reduces destination application The priority of Memory recycle operation is performed, it is as few to memory as possible when being operated in order to perform Memory recycle to application program Recycling protection application program performs Memory recycle operation, and is stored back in more being performed to the application program of non-Memory recycle protection It brings drill to an end work.

Certainly, predetermined time period can adjust according to actual needs with the first preset times, for example, system default is set Predetermined time period is five minutes, and the first preset times are that twice, user can change predetermined time period according to actual needs And first preset times, such as predetermined time period is revised as eight minutes, the first preset times are revised as three times.In addition, System can also determine the first preset times according to different application program actual conditions, it will be understood that each application program First preset times there are one corresponding, and corresponding first preset times of different application programs can differ.

Step S104, judges whether the memory value that destination application occupies is more than default memory value, if so, being transferred to step Otherwise S105, is transferred to step S105.

In step s 102, if it is determined that destination application is not Memory recycle protection application program, then it represents that can be with The Memory recycle operation of more number is performed to destination application or directly closes destination application.Certainly, it needs Determine close destination application standard, therefore, in the present embodiment, by memory value occupied to destination application come Determine whether to perform destination application Memory recycle operation or close application program.

Therefore, the memory value occupied in step S104 to destination application calculates.Specifically, obtain intended application The process that program is currently running for example, obtaining the process list of destination application, obtains the application program from process list All processes being currently running.Then, pass through the Activity Manager's of operating system GetProcessMemoryInfo can obtain the occupied memory information of each process.During due to obtaining process list The progress recognizing PID of each process is obtained, therefore, can each process be obtained according to the progress recognizing PID of process Shared memory information.The occupied memory of each process of destination application is added, you can to obtain destination application Occupied memory value.

One default memory value of operating system default setting, such as 100M.Certainly, user can also adjust this as needed Default memory value, such as it is adjusted to 150M or 200M.

Step S105 performs destination application in predetermined time period and is stored back in no less than the second preset times It brings drill to an end work.

In step S104, if it is determined that the memory value that destination application occupies is more than default memory value, represents target Application program occupies a large amount of memory source, then can be by way of memory discharge operation is performed a plurality of times by destination application Occupied memory source release.Specifically, multiple Memory recycle operation is performed in predetermined time period.Wherein, step The predetermined time period of S105 and the predetermined time period of step S 103 are identical time spans, be such as all three minutes or Five minutes.

Also, the Memory recycle number of operations performed in predetermined time period is no less than the second preset times, such as twice Or three times.In the present embodiment, the second preset times are a values for being more than or equal to the first preset times, for example, first Preset times are that twice, then the second preset times are twice or three times even more numbers.In this way it can be ensured that in phase In same time span, the Memory recycle number performed for non-Memory recycle protection application program receives protection more than internal be stored back to The Memory recycle number that application program performs.

Step S106 closes destination application.

If in step S104, determine that the memory value that destination application occupies is less than default memory value, then it represents that target Application program is not Memory recycle protection application program, and occupied memory value is smaller, therefore, should by closing target Memory recycle operation can be carried out to destination application with significantly more efficient with program.After destination application is closed, mesh The mark occupied memory of application program will be all released.

As it can be seen that for the application program in the higher application program of user's favorable rating, default white list and default class The application program of type, can be as few as possible execution Memory recycle operation, can reduce these application programs loading process when Between.For other applications, then multiple Memory recycle operation can be performed, so as to significantly more efficient to occupied by application program Memory recycled.

Certainly, when Memory recycle operation is performed to destination application, if continuously performing Memory recycle operation, having Probably due to the time of the adjacent operation of Memory recycle twice is too short and leads to what is recycled during second of execution Memory recycle operation Memory is considerably less, it is necessary to set the execution time of adjacent Memory recycle twice operation, Fig. 2 shows a kind of methods.

Step S201, it is not that Memory recycle protects application program and committed memory value is more than default to determine destination application Memory value.

Since Fig. 2 is that the Memory recycle carried out for non-Memory recycle protection application program operates, firstly the need of true The application program that sets the goal is not Memory recycle protection application program.And it is further desired that determine destination application committed memory value More than default memory value, because the smaller application program of committed memory value will be directly closed rather than perform Memory recycle behaviour Make.

Step S202 performs a Memory recycle operation.

After determining to need to perform destination application multiple Memory recycle operation, destination application can be performed Memory recycle operation.There are many kinds of the modes for performing Memory recycle operation, and common mode is to obtain destination application The target process being currently running such as obtains the process list of destination application, the mesh being carrying out is obtained from process list Mark process.Then the corresponding Physical Page of target process is obtained, and identifies the inactive Physical Page in Physical Page, it will be inactive Physical Page is recycled.

But if only being recycled to inactive Physical Page, then the efficiency of Memory recycle is very low, often leading to can not Fully recycling memory, therefore, the present invention also propose a kind of method that Memory recycle is carried out to active physical page, specific recycling side Method will be discussed in detail below.

Step S203 opens timer.

After a Memory recycle operation is performed, timing will be started, timing time was the first interval time, that is, twice Time between Memory recycle operation.It is adjacent interior to be twice stored back to for not being Memory recycle protection application program in the present embodiment Bring drill to an end interval time of work can set shorter, such as 60 seconds or 90 seconds.Certainly, user can voluntarily set the first interval The length of time.

Step S204 judges whether to reach for the first interval time, if so, performing step S205, otherwise, continues to execute step S204。

After opening timer, need to judge whether current timing time reached for the first interval time, such as judge timing Whether the time reaches 60 seconds or 90 seconds, if not reaching for the first interval time, will continue waiting for.

Step S205 judges whether to reach predetermined time period, if so, then terminating, otherwise, returns and performs step S202.

If current timing time reached for the first interval time, also need to judge whether to reach predetermined time period, If reaching predetermined time period, do not need to perform Memory recycle operation again, if reaching predetermined time period not yet, It then also needs to perform the operation of more Memory recycles, that is, returns and perform step S202, until reaching predetermined time period.

As it can be seen that by setting for the first interval time, it can be ensured that will not continuously perform within the very short time in repeatedly Reclaimer operation is deposited, is conducive to the more memories of application program and is recovered.

Certainly, application program is protected for Memory recycle, it is also desirable to limit twice in succession between the time of Memory recycle operation Every Fig. 3 shows the flow that the Memory recycle performed to Memory recycle protection application program operates.Certainly, the flow of Fig. 3 is performed On condition that the Memory recycle number that Memory recycle protection application program performs is more than twice.

Step S301, it is Memory recycle protection application program to determine destination application.

For example, in the step S102 of Fig. 1, to destination application whether be Memory recycle protection application program judgement As a result it is yes.

Step S302 performs a Memory recycle operation.

After determining to need to perform destination application multiple Memory recycle operation, destination application can be performed Memory recycle operation.There are many kinds of the modes for performing Memory recycle operation, and common mode is to obtain destination application The target process being currently running, and the inactive Physical Page to target process in corresponding Physical Page recycles.Certainly, this reality It applies example and Memory recycle also is carried out to active physical page, specific recovery method will be discussed in detail below.

Step S303 opens timer.

After a Memory recycle operation is performed, timing will be started, timing time was the second interval time, that is, twice Time between Memory recycle operation.In the present embodiment, application program, the adjacent behaviour of Memory recycle twice are protected for Memory recycle The interval time of work can set longer, such as 120 seconds or 180 seconds.Certainly, when user can voluntarily set the second interval Between length.

It should be noted that in the present embodiment, the length of the second interval time was more than for the first interval time, in order to The operating interval time of Memory recycle twice for allowing Memory recycle protection application program is longer, is performed in preset time so as to reduce The number of Memory recycle.

Step 3204, judge whether to reach for the second interval time, if so, performing step S305, otherwise, continue to execute step S304。

After opening timer, need to judge whether current timing time reached for the second interval time, such as judge timing Whether the time reaches 120 seconds or 180 seconds, if not reaching for the second interval time, will continue waiting for.

Step S305 judges whether to reach predetermined time period, if so, then terminating, otherwise, returns and performs step S302.

If current timing time reached for the second interval time, also need to judge whether to reach predetermined time period, If reaching predetermined time period, do not need to perform Memory recycle operation again, if reaching predetermined time period not yet, It then also needs to perform the operation of more Memory recycles, that is, returns and perform step S302, until reaching predetermined time period.

As it can be seen that in the present embodiment, the operation that Memory recycle is performed to application program is separately performed a plurality of times, and adjacent There are certain time intervals for Memory recycle operation twice, in this way can be to avoid multiple reclaimer operation is continuously performed, on the one hand The considerations of for performance, the operation of the present embodiment are conducive to improve the performance of terminal device, another reverse side, since application program exists The active of backstage can constantly generate the new page, if carrying out page aging in the very short time, continuously perform multiple memory The Memory recycle that reclaimer operation will be quickly completed application program, and newly generated physical page cannot recycle below, it can only Kswapd processes dependent on system realize Memory recycle, influence the quality of Memory recycle instead.

The present invention is to obtain destination application currently first to the Memory recycle operation that destination application carries out The target process of operation such as obtains the process list of destination application, so that it is determined that destination application is currently running Target process, the operation of Memory recycle is then performed to each target process respectively.Performing Memory recycle operation is mainly Physical Page is recycled, and judges that the value height of Physical Page storage data can have many angles, the prior art usually with The active degree of Physical Page（Or liveness）Height come evaluate Physical Page storage data value height, the liveness of Physical Page Higher, system has been generally acknowledged that the value of Physical Page storage data is higher.In order to compare the liveness of Physical Page, the prior art is drawn Enter in the recent period at least using chained list LRU, arranged according to recent service condition, at least use there are chained list ends. Physical Page in this 4 chained lists of INACTIVE_ANON, ACTIVE_ANON, INACTIVE_FILE and ACTIVE_FILE is can With recycling, ANON represents anonymous mapping, and FILE represents File Mapping, and INACTIVE is represented in inactive state, ACTIVE Representative is in active state, and the liveness of the Physical Page in ACTIVE chained lists is higher than the Physical Page in INACTIVE chained lists, also It is to say, the Physical Page being in active state, its liveness is higher than the Physical Page in inactive state.When low memory, System can preferentially recycle the Physical Page in the INACTIVE_ANON in LRU and INACTIVE_FILE the two chained lists, When process needs the content on the Physical Page using recycling, need to load corresponding contents from disk.

But the application process of front stage operation or the high application process of the priority of running background, the physics occupied Page may also be in INACTIVE_ANON and INACTIVE_FILE the two chained lists, to foreground process in the two chained lists and The corresponding Physical Page of the high process of backstage priority is recycled, and can greatly increase the number of system disk read-write, and And increase the waiting time of user, reduce user experience.

As it can be seen that application process also should be used as a weight of evaluation Physical Page value height.For this purpose, the prior art proposes needle The method that Memory recycle is carried out to process, the first selected target process as Memory recycle object, and obtain target process Physical Page is searched later not by target physical page that target process uses and recycles target physical page, do not used by target process Target physical page refer mainly to the Physical Page in inactive state.

In actual scene test, the backstage process of one minute is fallen back on for one, all Physical Page occupied to it into Row recycling, wherein, Physical Page of the process in INACTIVE_ANON and INACTIVE_FILE chained lists only takes up property The 5% of page ratio is managed, and most of Physical Page is Physical Page of the process in ACTIVE_ANON and ACTIVE_FILE chained lists. As it can be seen that the existing method organic efficiency that Memory recycle is carried out for process is very low.

In order to improve organic efficiency, need to select the Physical Page in ACTIVE_ANON and ACTIVE_FILE chained lists Property recycling, it is preferred that be to recycle wherein to be worth relatively low Physical Page, in other words, the relatively low Physical Page of liveness.Therefore, originally When embodiment carries out Memory recycle for the target of destination application, using step as shown in Figure 4：

Step S401 obtains the corresponding target physical page of target process.

The virtual memory that the mode of the corresponding Physical Page of acquisition process according to progress recognizing PID, can find process is empty Between VMA, traversal VMA can find the corresponding Physical Page of process, can also the corresponding Physical Page of lookup process by other means, It is not specifically limited herein.Target physical page can be the corresponding whole Physical Page of target process, or target process pair The part physical page answered.The recycling of target process can be carried out by serial mode, that is to say, that recycling only selection one every time A Physical Page performs the recovery process of the present invention or can also be carried out by parallel mode as target physical page, that is, Say that the multiple Physical Page of simultaneous selection as target physical page, are performed simultaneously multiple Physical Page the recovery process of the present invention.

Step S402 reads the value of the liveness of target physical page.

After obtaining the corresponding target physical page of target process, the value of the liveness of target physical page, target can be read The liveness of Physical Page is for the active level of marking target reason page, value and the target physical page of the liveness of target physical page Active level positive correlation, that is to say, that the active level of Physical Page is higher, then the value of its liveness is bigger.Also, Physical Page The selectable value of liveness should be no less than two.

It should be noted that the value of liveness can be numerical value, the value of liveness can be determined according to numerical values recited at this time Size, still, the value of liveness should not only be limited to numerical value, as long as can determine the height of different value according to preset standard of comparison It is low.

Step S403 if the value of the liveness of target physical page is higher than recycling standard, reduces enlivening for target physical page Degree, the value of liveness are in active state higher than the Physical Page of recycling standard.

After the value for reading the liveness of target physical page, it can be determined that whether the value of the liveness of target physical page is higher than Recycling standard, the value of liveness are in active state higher than the Physical Page of recycling standard, and recycling standard can be considered as moving type Boundary value between the liveness of the liveness of the Physical Page of state and the Physical Page of inactive state.If it is determined that the work of target physical page The value of jerk is higher than recycling standard, then can reduce the liveness of target physical page, if it is determined that the liveness of target physical page Value can then perform other operations, such as recycling target physical page not higher than recycling standard.

Step S404 reads again the value of the liveness of target physical page.

After step S403, the value of the liveness of target physical page can be read.If before step S404, in step Read target physical page is accessed in S403, then the value of the liveness of the target physical page can increase.If in step Before S404, read target physical page is not accessed in step S403, then the value of the liveness of target physical page will After maintaining step S403 operation, that is, the value that is lowered after liveness.

Step S405 if the value of the liveness of target physical page is not higher than recycling standard, recycles target physical page.

After the value for reading again the liveness of target physical page, it can be determined that whether the value of the liveness of target physical page Higher than recycling standard, if the value of the liveness of target physical page is not higher than recycling standard, target physical page is recycled.If object When managing the value of the liveness of page not higher than recycling standard, show that target physical page is in inactive state, the prior art has very much To the method that the Physical Page of inactive state is recycled, therefore the present embodiment is repeated no more to the Physical Page of inactive state Recovery method.

In the present embodiment, aging, such as the liveness reduction that will enliven the page of active carry out the page by active Realize the recycling to enlivening the page.Certainly, during active aging target physical page, system can also be made full use of Kswapd processes carry out aging to target physical page, such as when target physical page is reduced, can call kswapd processes, The operation reduced using kswapd processes to the liveness of target physical page can more be filled using system resource, be reached in this way More preferably result.

Certainly, in the first Memory recycle mode, if the time interval between step S403 and step S404 is extremely short, Under limiting case, it is possible to understand that after the liveness that target physical page is reduced into step S403, directly perform step S404 and read The value of the liveness of target physical page, if there are two the selectable value of liveness, in this way, the corresponding place of nearly all target process It is recovered in the Physical Page of active state, target process is automatically closed in the system of being equivalent to, and increases user's waiting time.Therefore, It needs to increase mechanism of going back on one's word in the first embodiment, such as between step S403 and step S404 between setting reasonable time Every as duration of going back on one's word, if target physical page is accessed in the time interval of setting, the value raising of liveness reduces The possibility being recovered, the Physical Page for being conducive to prevent liveness higher are recovered.Based on this thinking, the present invention should to target Flow chart with the target process method for recovering internal storage second way of program is as shown in Figure 5.

Step S501 obtains the corresponding target physical page of target process.

Step S502 sets the priority of preset duration, preset duration and target process according to the priority of target process Positive correlation.

Duration of going back on one's word may also be referred to as preset duration, can be the fixation duration of system default, it is preferred that determining to be directed to After target process is recycled, when can read target process priority, and be preset according to the setting of the priority of target process It is long, so that the priority positive correlation of preset duration and target process, that is to say, that the higher process of priority is set for it Preset duration it is longer.

Alternatively, preset duration can also be set according to memory usage, preset duration is negatively correlated with memory usage, also It is to say, memory usage is higher, then preset duration is shorter, and organic efficiency is higher, to recycle more memories as early as possible.

Step S503, reads the value of the liveness of target physical page, and the liveness of target physical page is used for marking target Manage the active level of page, the value of the liveness of target physical page and the active level positive correlation of target physical page.

Whether step S504 judges the value of liveness of target physical page higher than recycling standard, if so, performing step S505, if it is not, then performing step S507.

After the value of liveness of target physical page is read, it can be determined that whether the value of the liveness of target physical page is high In recycling standard, the value of liveness is in active state higher than the Physical Page of recycling standard, if so, step S505 is performed, if It is no, then perform step S507.

Step S505 reduces the liveness of target physical page.

If it is determined that the value of the liveness of target physical page is higher than recycling standard, then enlivening for target physical page can be reduced Degree.

Step S506 opens timer.

After the liveness for reducing target physical page, timer can be opened, records duration.When the duration of timer record When reaching preset duration, repeating step S503 to step S504 can only be repeated once, that is to say, that if repeating for the first time When performing step S504, still judge that the value of the liveness of target physical page is higher than recycling standard, then no longer perform step S505, But directly exit the recovery process to target physical page, that is to say, that the Physical Page of active state is only once recycled It attempts.In order to improve organic efficiency, more memories are recycled, it is preferred that the Physical Page of active state is carried out twice or twice Above recycling is attempted, that is to say, that step S503 to step S504 can be repeated twice or more than twice.

Number of repetition can be preset as some finite value, and actual scene test result shows what preceding recycling three times was attempted Organic efficiency higher, it is very low that organic efficiency is attempted in the 4th time and recycling later, therefore number of repetition could be provided as three times.Separately Outside, can also number of repetition be set according to memory usage, memory usage is higher, and recovered frequency is more.Alternatively, actually making In, number of repetition can also be configured according to other considerations, the present embodiment does not limit this.

It should be noted that the execution sequences of step S502 in embodiments of the present invention are not limited to the suitable of foregoing description Sequence, since preset duration is used for step S506, as long as being performed before step S506, specific sequential does not limit.

Step S507 recycles target physical page.

If the value of the liveness of step S508 judgement target physical pages recycles target physical page not higher than recycling standard.

Mechanism of going back on one's word set by the present invention, in addition in such as second of implementation, by setting reasonable time interval, As duration of going back on one's word, it is recovered with the Physical Page for preventing liveness higher as possible, it can also be to being higher than the liveness of recycling standard Two or more is set optionally to be worth, is recovered in this way, the higher Physical Page of liveness is more difficult in recycling is attempted. Therefore, the present invention carries out the target process of destination application flow such as Fig. 6 of the third embodiment of method for recovering internal storage It is shown.

Step S601 sets the selectable value of Physical Page liveness, including the first value, second value, third value and the 4th value.

The selectable value of Physical Page liveness is set, for example the first value, second value, third value and the 4th value can be included, In, the first value is not higher than recycling standard, and second value is less than third value, and higher than recycling standard, and third value is less than the 4th value.Or It can be said that each selectable value represents the series of the liveness of Physical Page, value is higher, and the series of liveness is higher.

As an example, the active level of Physical Page can be assessed by setting flag bit, it is assumed that two flag bits of setting, The selectable value of each flag bit is 0 and 1, and the value of liveness can be used（First mark bit value, the second mark bit value）Carry out generation Table, then the selectable value of liveness includes（0,0）、（0,1）、（1,0）With（1,1）, and default standard of comparison（0,0）It is less than（1, 0）It is less than（0,1）It is less than（1,1）, that is to say, that（0,0）、（1,0）、（0,1）、（1,1）It increases step by step.

In actual use, the range of selectable value can also be set, without specifically setting each value.

Step S602 obtains the corresponding target physical page of target process.

Step S603 reads the value of the liveness of target physical page.

Step S602 to step S603 is identical to step S402 with the step S401 in the first embodiment respectively, herein It repeats no more.

Whether step S604 judges the value of liveness of target physical page higher than recycling standard, if so, performing step S605, if it is not, then performing step S607.

After the value of liveness of target physical page is read, it can be determined that whether the value of the liveness of target physical page is high In recycling standard, the value of liveness is in active state higher than the Physical Page of recycling standard, if so, step S605 is performed, if It is no, then perform step S607.

Step S605, according to the liveness of the first amplitude reduction target physical page.

If it is determined that the value of the liveness of target physical page is higher than recycling standard, then it can be according to the first amplitude reduction object The liveness of page is managed, in embodiments of the present invention, the first amplitude can be to reduce level-one every time.

Step S606 opens timer.

Preset duration can be provided with, as duration of going back on one's word, about the setting of preset duration, please refers to second of embodiment party Formula is repeated no more in the present embodiment.

When the duration of timer record reaches preset duration, step S603 is repeated to step S604.It can be only heavy It is multiple primary, that is to say, that if repeat step S604 for the first time, still to judge that the value of the liveness of target physical page is higher than Recycling standard then no longer performs step S605, but directly exits the recovery process to target physical page, that is to say, that work The Physical Page of dynamic state is only carried out once recycling and be attempted.In order to improve organic efficiency, more memories are recycled, it is preferred that work The recycling that the Physical Page of dynamic state carries out twice or more than twice is attempted, that is to say, that can be to step S603 to step S604 It repeats twice or more than twice.

Number of repetition can be preset, and actual scene test result shows the preceding organic efficiency higher for recycling trial three times, the It is very low that organic efficiency is attempted in four times and recycling later, therefore number of repetition could be provided as three times.Alternatively, it is also possible in Occupancy setting number of repetition is deposited, memory usage is higher, and recovered frequency is more.Alternatively, in actual use, it can also basis Other considerations are configured number of repetition, do not limit herein.

Step S607 recycles target physical page.

If the value of the liveness of target physical page is not higher than recycling standard, target physical page is recycled.

Below as the method that 3rd embodiment provides, with the different situations of the value of the liveness read for the first time lift Example explanation, it is assumed that the maximum of step S603 to step S604 repeat number and is set as 3 times：

First, assume that target physical page is not accessed, and the value of liveness does not increase during trial is recycled, then：

If the value for reading the liveness of target physical page for the first time is the 4th value, then after performing step S605, target physical page The value of liveness is arranged to third value, step S603 to step S604 is repeated for the first time later, due to the value of liveness Standard is still higher than recycled, continues to reduce level-one to the value of liveness, is set as second value, repeats step for the second time later S603 to step S604 since the value of liveness is still higher than recycling standard, continues to reduce level-one to the value of liveness, be set as First value repeats step S603 to step S604 for the third time later, since the value of liveness is not higher than recycling standard, to mesh Mark Physical Page is recycled.If the value for reading the liveness of target physical page for the first time is the 4th value, then the Physical Page at least needs To repeat step S603 to step S604 three times can be recovered.

If the value for reading the liveness of target physical page for the first time is third value, then after performing step S605, target physical The value of the liveness of page is arranged to second value, step S603 is repeated for the first time later to step S604, due to liveness Value be still higher than recycling standard, continue to reduce level-one to the value of liveness, be set as the first value, repeat for the second time later Step S603 to step S604 since the value of liveness is not higher than recycling standard, recycles target physical page.If it reads for the first time The value for taking the liveness of target physical page is third value, then the Physical Page at least needs to repeat step S603 twice to step Rapid S604 can be recovered.

If the value for reading the liveness of target physical page for the first time is second value, then after performing step S605, target physical The value of the liveness of page is arranged to the first value, step S603 is repeated for the first time later to step S604, due to liveness Value not higher than recycling standard, target physical page is recycled.If the value for reading the liveness of target physical page for the first time is the Two-value, then the Physical Page is at least needed once to repeat step S603 to step S604 and can be recovered.

If the value for reading the liveness of target physical page for the first time is the first value, since the value of liveness is marked not higher than recycling Standard recycles target physical page.If the value for reading the liveness of target physical page for the first time is the first value, then the Physical Page Step S603 to step S604 is not needed to repeat with regard to that can be recovered.

As it can be seen that before the recycling step for performing the present invention, the higher Physical Page of the value of liveness is less susceptible to be returned Receive, that is to say, that the present invention can the relatively low Physical Page of priority reclamation liveness, realize to the fine of the Physical Page of active state Change classification recycling.

2nd, assume that target physical page is accessed, then the value of its liveness can increase during trial is recycled, then It is compared with the first situation, system needs more recycling to attempt that target physical page could be recycled.In practical application In, the recycling that system usually carries out Physical Page finite number of time is attempted, if after the recycling of finite number of time is attempted, target physical page The value of liveness be still higher than recycling standard, then show that the liveness of target physical page is very high, be for target process Higher Physical Page is worth, system will not recycle target physical page, be obtained between process operational effect and memory source abundance More rational balance.

Further, target process carry out recycling trial movable Physical Page include target process in ACTIVE_ Physical Page in ANON chained lists（That is the anonymous page of active state）The corresponding Physical Page in ACTIVE_FILE chained lists（It is i.e. movable The file page of state）.Wherein, the way of recycling of anonymous page is exchanged for page, and time-consuming for recycling, and efficiency is low；And the recycling of file page Mode is abandoned for page or page write-back, and recycling is time-consuming short, efficient.As it can be seen that the recycling cost higher of the anonymous page to active state, Therefore it is compared with the anonymous page of active state, the recovery difficult to the file page of active state can be reduced, improve file page Probability is recycled, more file page is recycled, to improve the recycled in its entirety efficiency to movable Physical Page.

Increase the recovery difficult to the anonymous page of active state, a variety of methods may be used, for example, anonymous page can be increased Duration of going back on one's word, for example the selectable value of liveness can be reduced or reduction amplitude to liveness can also be increased.Here, The third mode is illustrated in we, if 3rd embodiment is used for the recycling of anonymous page, then refer to 7, the present invention The 4th embodiment of Memory recycle is carried out to the target process of destination application to include the following steps：

Step S701 sets the selectable value of Physical Page liveness, including the first value, second value, third value and the 4th value.

Step S702 obtains the corresponding target physical page of target process.

Step S703 reads the value of the liveness of target physical page.

Step S702 to step S703 is identical to step S402 with the step S401 in first embodiment respectively, herein no longer It repeats.

Whether step S704 judges the value of liveness of target physical page higher than recycling standard, if so, performing step S705, if it is not, then performing step S707.

After the value of liveness of target physical page is read, it can be determined that whether the value of the liveness of target physical page is high In recycling standard, the value of liveness is in active state higher than the Physical Page of recycling standard, if so, step S705 is performed, if It is no, then perform step S707.

Step S705, if the type of target physical page is file page, according to the work of the second amplitude reduction target physical page Jerk.

It, can be with before the liveness for reducing target physical page after the corresponding target physical page of target process is obtained The reduction amplitude of its liveness is set according to the type of target physical page.When target physical page is anonymous page, then according to the The liveness of one amplitude reduction target physical page；When target physical page is file page, then according to the second amplitude reduction object The liveness of page is managed, and the first amplitude is less than the second amplitude.In the third embodiment, the first amplitude, can be with to reduce level-one As the recovery process when target physical page is anonymous page, details are not described herein again.It is mainly used for illustrating in the present embodiment When the type of target physical page is file page, to the recovery process of target physical page.Since the first amplitude is less than the second amplitude, The second amplitude can be to reduce two-stage every time so in the present embodiment.

Step S706 opens timer.

Preset duration can be provided with, as duration of going back on one's word, about the setting of preset duration, refers to second embodiment, It is repeated no more in the embodiment of the present invention.

When the duration of timer record reaches preset duration, step S703 is repeated to step S704.It can be only heavy It is multiple primary, that is to say, that if repeat step S703 to step S704 for the first time, still to judge enlivening for target physical page The value of degree is higher than recycling standard, then no longer performs step S705, but directly exits the recovery process to target physical page, also It is to say, the Physical Page of active state is only carried out once to recycle and is attempted.In order to improve organic efficiency, more memories are recycled, it is excellent Choosing, the recycling carried out twice or more than twice to the Physical Page of active state is attempted, that is to say, that can be to step S703 extremely Step S704 is repeated twice or more than twice.

Step S707 recycles target physical page.

Below as the method that fourth embodiment provides, with the different situations of the value of the liveness read for the first time lift Example explanation, it is assumed that the maximum of step S703 to step S704 repeat number and is set as 3 times：

If the value for reading the liveness of target physical page for the first time is the 4th value, then after performing step S705, target physical page The value of liveness is arranged to second value, step S703 to step S704 is repeated for the first time later, due to the value of liveness Standard is still higher than recycled, continues to reduce two-stage to the value of liveness, since minimum series is the first value, is set as the One value repeats step S703 to step S704 for the second time later, since the value of liveness is not higher than recycling standard, to target Physical Page is recycled.If the value for reading the liveness of target physical page for the first time is the 4th value, then the Physical Page at least needs Repeating step S703 to step S704 twice can be recovered.

If the value for reading the liveness of target physical page for the first time is third value, then after performing step S705, target physical The value of the liveness of page is arranged to the first value, step S703 is repeated for the first time later to step S704, due to liveness Value not higher than recycling standard, target physical page is recycled.If the value for reading the liveness of target physical page for the first time is the Three values, then the Physical Page is at least needed once to repeat step S703 to step S704 and can be recovered.

If the value for reading the liveness of target physical page for the first time is second value, then after performing step S705, target physical The value of the liveness of page is arranged to the first value, step S703 is repeated for the first time later to step S704, due to liveness Value not higher than recycling standard, target physical page is recycled.If the value for reading the liveness of target physical page for the first time is the Two-value, then the Physical Page is at least needed once to repeat step S703 to step S704 and can be recovered.

If the value for reading the liveness of target physical page for the first time is the first value, since the value of liveness is marked not higher than recycling Standard recycles target physical page.If the value for reading the liveness of target physical page for the first time is the first value, then the Physical Page Step S703 to step S704 is not needed to repeat with regard to that can be recovered.

Compared with third embodiment, present embodiment is advantageously reduced by increasing the reduction amplitude of the value of liveness Step S703 repeats number to step S704's, improves the organic efficiency to the file page of active state.

It can be realized respectively to target process in work by the method for 3rd embodiment and the method for fourth embodiment The recycling of the anonymous page and file page of dynamic state, such as the following table 1 are the method according to the method and fourth embodiment of 3rd embodiment Carry out the actual scene test of page recycling.It is understood that the knot that the test data in table 1 is only once tested Fruit, when testing again, due to the use of terminal it is different, to service condition difference of application program etc., can lead to test data Variation, therefore, the data of table 1 are only used for qualitative illustrating the present invention to the recovering effect of each application rather than quantitative limiting The present invention is to the organic efficiency of each application.

Table 1

Respectively with bean cotyledon, QQ, wechat, today's tops, QQ browsers, mobile phone house keeper, using center and Sina weibo etc. application make For intended application, i.e. test object, using the process in intended application as target process, page recycling is carried out to target process, To realize the Memory recycle to intended application.By taking bean cotyledon as an example, during the test, the anonymity first to the target process of bean cotyledon Page performs a step S603 and performs a step S703 to step S704 to step S604 or to its file page, referred to as pair Bean cotyledon carries out first time recycling, after recycling according to the memory size of bean cotyledon occupancy before recycling test and for the first time in bean cotyledon occupancy Size is deposited, the first time rate of recovery to bean cotyledon can be calculated, is 2.64%；Later to the anonymous page of the target process of bean cotyledon Second of execution step S603 performs step S703 to step S704 second to step S604 or to its file page, referred to as It is recycled to carry out second to bean cotyledon, bean cotyledon accounts for after the memory size occupied according to bean cotyledon after recycling for the first time and second of recycling Second of rate of recovery to bean cotyledon can be calculated in memory size, be 8.27%；The rest may be inferred, can obtain to bean cotyledon The third time rate of recovery be 26.73%, be 0.46% to the 4th rate of recovery of bean cotyledon, be to the 5th rate of recovery of bean cotyledon 0.08%。

Observe the same application rate of recovery that homogeneous does not recycle in table 1, it can be seen that respectively apply equal in the preceding rate of recovery three times It is far longer than the rate of recovery of the 4th time and the 5th time, also, the accumulative rate of recovery recycled three times（After being recycled according to third time The memory size occupied using application before the memory size of occupancy and recycling test is calculated）With accumulative five recycling of progress The rate of recovery is not much different, and illustrates that recovered frequency is excessive, and organic efficiency is not high, and waste of resource, it is therefore preferred to application into The page recycling of row finite number of time.

In addition, the existing method recycled for process, only recycles the Physical Page of inactive state, recycle Rate corresponds to the first time rate of recovery in table 1, is carried out three times with accumulative by comparing the first time rate of recovery of same application in table 1 The rate of recovery of recycling, it is found that the latter is the former several times, and multiple is between 2 times to 17 times, it is seen then that and prior art phase Than the present invention realizes the higher rate of recovery, has positive effect for alleviating Installed System Memory pressure.

In conclusion the present invention provides a kind of method that Memory recycle is carried out for process, and can be to moving type The Physical Page of state carries out selective recovery, greatly improves the efficiency of Memory recycle.Also, due to being directed to different types of answer With program using different Memory recycle strategies, such as the more favorite application program of user, Memory recycle operation is performed Number is less, and for the relatively low application program of user's favorable rating, then the number for performing Memory recycle operation is more, so as to keep away Exempt from the more favorite application program on user influences response speed due to the operation that frequent executive process loads.

Certainly, in order to which terminal device is allowed to recycle memory in time, user can set a free memory threshold value, such as 200M, If the current memory of terminal device is less than the threshold value, terminal device operates automatic trigger Memory recycle, such as obtains terminal The destination application that equipment is currently running, and the flow such as Fig. 1 is performed, so as to fully recycle the memory of terminal device.It is excellent Choosing, system can set a threshold value given tacit consent to or by the user setting threshold value.If during by the user setting threshold value, User can set the threshold value according to actual use situation.

Further, since the speed of service of terminal device will be influenced by performing Memory recycle operation, terminal is set in order to reduce The influence of the standby speed of service, terminal device can just perform Memory recycle operation when loading smaller situation, for example, in terminal Equipment, which is in when screen lock state either ceases screen state, to be performed Memory recycle operation or is in suspend mode or non-work in terminal device Make to perform Memory recycle operation during state or Memory recycle operation is performed when the load of CPU is relatively low.Certainly, it needs to set A cpu load threshold value is put, determines that the load of CPU is relatively low when the load of CPU is less than the load threshold, can be performed at this time interior Deposit reclaimer operation.
