Description

Thread information adjustment method and device and electronic equipment

Technical Field

The present invention relates to the field of computer technologies, and in particular, to a thread information adjustment method, a thread information adjustment device, and an electronic device.

Background

The operating system generally includes two parts: kernel space running in privileged mode and user space running in non-privileged mode. Since the kernel is the core of the operating system, it manages all the resources in the system and serves upper applications, and therefore needs to run in kernel space. The cores can be divided into different architectures according to the difference of functions realized by the cores, and in different core architectures, the providing mode of system services and the realization mode of hardware driving are different, so that the overall performance and development difficulty of the system are affected. Currently, common core architectures include three types, macro core (Monolithic Kernel), micro core (Microkernel), and Hybrid Kernel (Hybrid Kernel).

Under the micro-kernel architecture, some components such as a driver, application management, a file system and the like are divided into user mode, and some modules can be developed by different manufacturers and downloaded or version-up after being released in an operating system supporting the downloading of the modules. These modules are typically run as kernel mode programs in macro kernel or hybrid kernel architectures, with higher rights and running priorities. After being downloaded as a user mode program, the user mode program becomes a process or thread combination of the user mode, and execution confusion can occur on the scheduling priority and the time slices if the user mode program is only set by a developer and is not managed.

Detailed Description

The following describes the detailed implementation of the embodiments of the present invention with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.

Method embodiment

The embodiment of the invention provides a thread information adjustment method which is applied to a first terminal. The first terminal can be a personal computer, a desktop computer, a tablet personal computer, a smart phone or other devices. Referring to fig. 1, a thread information adjustment method according to an embodiment of the present invention includes:

and step 101, receiving an application program installation file sent by the second terminal.

The first terminal may receive the application installation file sent by the second terminal through a wired (data line) or wireless (WI-FI, bluetooth, operator network, etc.) mode. The application installation file comprises an application download file and adding information.

The adding information comprises a priority reference value, a priority dynamic range value, a time slice reference value and a time slice dynamic range value which are set by the second terminal for the application program which is correspondingly operated by the application program downloading file. The second terminal may be various terminals that can add information to the application download file, for example, the second terminal may be a server.

The priority reference value is a thread priority minimum value set or specified by the second terminal for the application program corresponding to the application program downloading file. The priority dynamic range value is a maximum range value that increases on the basis of the priority reference value. Wherein, different application programs can be classified and graded, and the thread priority reference value and the priority dynamic range of each application program are set. For example, when the importance level of the application 1 is higher than that of the application 2, and the importance level is higher as the priority is lower, the priority reference value of the thread of the application 1 is set to 10, and the priority dynamic range value is set to 10; the priority reference value of the thread of the application 2 is 20 and the priority dynamic range value is 10.

The time slice reference value is a minimum time slice value set or specified by the second terminal for the thread of the application program corresponding to the running application program downloading file. The time slice dynamic range value is a maximum range value that increases on the basis of the time slice reference value.

And step 103, adjusting the priorities of all threads of the application program based on the priority reference value and the priority dynamic range value.

The first terminal analyzes the application program installation file through the application executor to obtain an application program downloading file and adding information, and stores the application program downloading file into a nonvolatile memory in an embedded operating system of the first terminal. Referring to fig. 2, when the application executor parses and executes the application, all threads of the application are mounted in a thread waiting area, and the first terminal adjusts the priorities of all threads of the application program based on the priority reference value NewPrioBase and the priority dynamic range value NewPrioRng, so that the priorities of all threads of the application program are in a range from the priority reference value to a value range where the priority reference value and the priority dynamic range value are added. For example, the application 1 has 5 threads with priorities of 1, 5, 3, 7, and 9, and the first terminal adjusts the priority reference value to 10 in the added information part and the priority dynamic range value to 10, and then all the threads of the application 1 after adjustment are adjusted to 10, 14, 12, 16, and 18.

And step 104, adjusting the time slices of all threads of the application program based on the time slice reference value and the time slice dynamic range value.

The first terminal adjusts the time slices of all threads of the application based on the time slice reference value NewSliceBase and the time slice dynamic range value NEWSLICERNG so that the time slices of all threads of the application are between the time slice reference value and the numerical range where the time slice reference value and the time slice dynamic range value are added. For example, the application 1 has 1 thread, the time slice is 700ms, the first terminal adjusts the time slice reference value to 100ms and the time slice dynamic range value to 600ms in the addition information part, and the time slice of the adjusted thread is adjusted to 100+600=700 ms. For another example, the application 1 has 1 thread, the time slice is 800ms, the first terminal adjusts the time slice reference value to 300ms in the addition information part, and the time slice dynamic range is 200ms, and the time slice of the adjusted thread is 300+200=500 ms.

According to the embodiment of the invention, the priority of all threads of the application program is adjusted based on the priority reference value and the priority dynamic range value included in the application program installation file by receiving the application program installation file sent by the second terminal; the time slices of all threads of the application are adjusted based on the time slice reference values and the time slice dynamic range values included in the application installation file. By setting the information adding mode for the application program downloading file, the priority and time slice information of all threads in the application program corresponding to the application program downloading file can be adjusted or managed so as to meet the actual requirement of the application program operation and avoid the defect of disordered execution of the application program.

In other aspects of the embodiments of the present invention, step 103, adjusting the priority of all threads of the application program based on the priority reference value and the priority dynamic range value includes:

step 1031, determining the original thread priority range value.

The first terminal determines an original thread priority range value. In one embodiment, the original thread priority range value may be stored in a non-volatile memory of the first terminal, and the first terminal may obtain the original thread priority range value from the non-volatile memory, thereby determining the original thread priority range value.

Step 1032, adjusting the priorities of all threads of the application program based on the original thread priority range value, the priority reference value and the priority dynamic range value.

The first terminal adjusts the priorities of all threads of the application program based on the original thread priority range value, the priority reference value and the priority dynamic range value, so that the priorities of all threads of the application program are in a range from the priority reference value to the value range where the priority reference value and the priority dynamic range value are added.

Further, step 1031, determining an original thread priority range value, includes:

Step 10311, prioritizing all threads of the application to determine an original thread priority maximum and an original thread priority minimum.

Referring to fig. 3, the first terminal may put all threads of the application into a two-dimensional set, including a thread name and a thread priority, where the thread name Tn corresponds to the thread priority TPn one by one, and may form an array or a linked list data structure. The number of the bus threads is n; { T1, T2, …, tn; TP1, TP2, …, TPn }. Wherein, T1 is a thread name, TP1 is a thread priority corresponding to the thread name T1, and the correspondence between the remaining thread names and the thread priorities is similar.

The first terminal ranks the priorities of all threads of the application program according to the priority order from high to low or from low to high, and determines the maximum value and the minimum value of the priority of the original threads. It should be noted that, in some embodiments, the smaller the priority value set by the embedded operating system, the higher the thread execution priority; the greater the priority value set by some embedded operating systems, the higher the thread execution priority. In this embodiment, the priority values may be sorted in order from large to small or from small to large, and the embodiment of the present invention only selects the maximum value and the minimum value of the original thread priority.

Step 10312, determining an original thread priority range value based on the difference between the original thread priority maximum value and the original thread priority minimum value.

And the first terminal determines an original thread priority range value based on the difference value between the original thread priority maximum value and the original thread priority minimum value. For example, the priorities of the original 5 threads of the application program 1 are 1, 5,3, 7 and 9, respectively, and then the original thread priority range value=the original thread priority maximum value-the original thread priority minimum value=9-1=8.

In other aspects of the embodiments of the present invention, step 1032, adjusting the priorities of all threads of the application program based on the original thread priority range value, the priority reference value, and the priority dynamic range value includes:

Referring to fig. 4, in the case where the priority range value OldPrioRng of the original thread is less than or equal to the priority dynamic range value NewPrioRng, it is indicated that the priority dynamic range value is sufficient for the thread of the application to adjust according to the absolute value of the original priority, and then a linear adjustment method may be used for adjustment. The first terminal determines the priority of the first thread of the application program after adjustment based on the original priority of the first thread of the application program, the priority reference value and the original thread priority minimum value.

Further, based on the original priority of the first thread of the application program, the priority reference value and the original thread priority minimum value, determining the adjusted priority of the first thread of the application program is realized by the following formula:

NewPrio_m＝OldPrio_m+NewPrioBase-OldPrioMin；

For example, if the application program 1 has 5 threads, the priorities are 1, 5, 3, 7 and 9, the priority reference value is 10, and the priority dynamic range value is 10, the priority after the priority of the original thread 1 is adjusted=1+10-1=10; priority after the original thread priority 5 is adjusted=5+10-1=14; priority after the original thread priority 3 is adjusted=3+10-1=12; priority after the original thread priority 7 is adjusted=7+10-1=16; the priority after the original thread priority 9 is adjusted=9+10-1=18. I.e. the application 1 has 5 threads with adjusted priorities of 10, 14, 12, 16, 18, respectively.

The invention determines the priority of the first thread of the application program after adjustment based on the original priority of the first thread of the application program, the priority reference value and the original thread priority minimum value, thereby adjusting or managing the priority of all threads in the application program corresponding to the application program downloading file so as to meet the actual requirement of the application program operation and avoid the defect of disordered execution of the application program.

In other aspects of the embodiments of the present invention, step 1022, adjusting the priorities of all threads of the application program based on the original thread priority range value, the priority reference value, and the priority dynamic range value includes:

If the original thread priority range value OldPrioRng is greater than the priority dynamic range value NewPrioRng, i.e., the priority dynamic range value is insufficient for the threads provided to the application to adjust according to the original priority absolute value, then a further determination of the relationship of the priority dynamic range value NewPrioRng to the total number of all threads of the application is required. If the priority dynamic range value NewPrioRng is greater than or equal to the total number n of all threads of the application program, indicating that the priority dynamic range value NewPrioRng is sufficient to provide the application with a priority relative value for adjustment, the first terminal determines the adjusted priority of the first thread of the application program based on the original priority of the first thread of the application program, the priority reference value, the original thread priority minimum value, the original thread priority range value, and the priority dynamic range value.

Further, the determining the priority of the first thread of the application program after adjustment based on the original priority of the first thread of the application program, the priority reference value, the original thread priority minimum value, the original thread priority range value and the priority dynamic range value is implemented by the following formula:

NewPrio_m＝NewPrioBase+(OldPrio_m-OldPrioBase)*NewPrioRng/OldPrioRng；

Wherein NewPrio _m represents the adjusted priority of the first thread of the application, oldPrio _m represents the original priority of the first thread of the application, newPrioBase represents the priority reference value, oldPrioBase represents the original thread priority minimum, newPrioRng represents the priority dynamic range value, and OldPrioRng represents the original thread priority range value. It should be noted that the calculation result of the formula may be rounded up or down. The present embodiment may round down the calculation of the formula.

Referring to fig. 5, (NewPrio _m-NewPrioBase)/(OldPrio_m -OldPrioBase) =cosα= NewPrioRng/OldPrioRng.

For example, if the application 2 has 5 threads, the priorities are 1, 5, 3, 7 and 9, the priority reference value is 20, and the priority dynamic range value is 5, the priority after the adjustment of the original thread priority 1=20+ (1-1) ×5/(9-1) =20; priority after the original thread priority 5 is adjusted=20+ (5-1) 5/(9-1) =22; priority after the original thread priority 3 is adjusted=20+ (3-1) 5/(9-1) =21; priority after the original thread priority 7 is adjusted=20+ (7-1) 5/(9-1) =23; the priority of the original thread after 9 adjustment=20+ (9-1) ×5/(9-1) =25. I.e. the adjusted 5 thread priorities of the application 2 are respectively 20, 22, 21, 23, 25.

The invention determines the priority of the first thread of the application program after adjustment based on the original priority of the first thread of the application program, the priority reference value, the original thread priority minimum value, the original thread priority range value and the priority dynamic range value, thereby adjusting or managing the priority of all threads in the application program corresponding to the application program downloading file so as to meet the actual requirement of application program operation and avoid the defect of disordered application program execution.

If the original thread priority range value OldPrioRng is greater than the priority dynamic range value NewPrioRng, i.e., the priority dynamic range value is insufficient for the threads provided to the application to adjust according to the original priority absolute value, then a further determination of the relationship of the priority dynamic range value NewPrioRng to the total number of all threads of the application is required. If the priority dynamic range value NewPrioRng is less than the total number n of all threads of the application program, indicating that the priority dynamic range value is insufficient to provide the priority relative value for the application program to adjust, the first terminal determines the adjusted priority of the first thread of the application program based on the original priority of the first thread of the application program, the priority reference value, the original thread priority minimum value, the total number of all threads of the application program, and the original thread priority range value.

Further, referring to fig. 6, determining the adjusted priority of the first thread of the application program based on the original priority of the first thread of the application program, the priority reference value, the original thread priority minimum value, the total number of all threads of the application program, and the original thread priority range value is implemented by the following formula:

NewPrio_m＝NewPrioBase+(OldPrio_m-OldPrioBase)*n/OldPrioRng；

It should be noted that, when the priority after the first thread adjustment of the application program is greater than the sum of the priority reference value and the priority dynamic range value, the priority after the first thread adjustment of the application program is determined to be the sum of the priority reference value and the priority dynamic range value. The calculation of the formula may be rounded up or down. The present embodiment may round down the calculation of the formula.

For example, the application program 3 has 5 threads with priorities of 1, 5, 3, 7 and 9, and the manager adjusts the thread reference value to 30 in the process signature modification information part and the dynamic range to 3, so that the priority of the original thread 1 is adjusted to be priority=30+ (1-1) 5/(9-1) =30; the original thread priority 5 is adjusted to be priority=30+ (5-1) 5/(9-1) =32; the original thread priority 3 is adjusted to be priority=30+ (3-1) 5/(9-1) =31; the original thread priority 7 is adjusted to be priority=30+ (7-1) 5/(9-1) =33; the priority level of the original thread priority 9 is adjusted to be=30+ (9-1) ×5/(9-1) =35, and 35 > 30+3=33, so the priority level of the original thread priority 9 is adjusted to be 33. I.e. 30, 32, 31, 33 after the adjustment of the 5 thread priorities of the adjusted application 3.

The invention determines the priority of the first thread of the application program after adjustment based on the original priority of the first thread of the application program, the priority reference value, the original thread priority minimum value, the total number of all threads of the application program and the original thread priority range value, thereby adjusting or managing the priority of all threads in the application program corresponding to the application program downloading file, meeting the actual requirement of the application program operation and avoiding the defect of disordered execution of the application program.

In other aspects of the embodiments of the present invention, step 104, adjusting the time slices of all threads of the application program based on the time slice reference value and the time slice dynamic range value includes:

Step 1041, calculating a time slice maximum value based on the sum of the time slice reference value and the time slice dynamic range value.

Step 1042, determining a time slice after the first thread of the application program is adjusted based on the magnitude relation between the original time slice of the first thread of the application program and the maximum time slice; wherein the first thread is any one thread of all threads of the application program.

For example, if the slice reference value is 100ms and the slice dynamic range value is 600ms, the slice maximum value is 100+600=700 ms. And the first terminal determines the time slice after the first thread of the application program is adjusted based on the size relation between the original time slice of the first thread of the application program and the maximum time slice.

Further, the determining the time slice after the first thread adjustment of the application program based on the magnitude relation between the original time slice of the first thread of the application program and the maximum time slice value includes:

Because the influence of the time slice on the call of the thread is smaller, a simpler setting method can be selected in the embodiment of the invention, namely, when the original time slice of the first thread of the application program is larger than or equal to the maximum time slice, the maximum time slice is determined to be the time slice after the first thread of the application program is adjusted. For example, comparing the original time slice NEWSLICEM of the first thread m in progress to the time slice maximum NewSliceMax, if the original time slice NEWSLICEM of the first thread is greater than the time slice maximum NewSliceMax, NEWSLICEM = NewSliceMax.

In other embodiments, the time slices of all threads of the application program may be optionally adjusted by the same method as the thread priority adjustment.

In other aspects of the embodiments of the present invention, referring to fig. 7, after the step of adjusting the time slices of all the threads of the application program based on the time slice reference value and the time slice dynamic range value, step 104 further includes:

Step 105, performing thread scheduling based on all threads of the adjusted application program.

And step 106, determining the running state of the target thread based on the CPU occupation time after the target thread is started and/or based on the keep-alive mechanism of the target thread. The target thread is any one of all threads of the application program.

Referring to fig. 8, the first terminal mounts all threads of the adjusted application program to the thread waiting area, and performs thread scheduling based on all threads of the adjusted application program. The first terminal determines the running state of the target thread based on the CPU occupation time after the target thread is started and/or based on the keep-alive mechanism of the target thread, so that the thread of the application program can be correctly executed after modification. That is, in one embodiment, the first terminal determines the running state of the target thread based on the CPU occupation time after the target thread is started, so as to determine that the thread of the application program can be correctly executed after modification. In another embodiment, the first terminal determines the running state of the target thread based on the keep-alive mechanism of the target thread, so as to determine that the thread of the application program can be correctly executed after modification. In another embodiment, the first terminal determines the running state of the target thread based on the CPU occupation time after the target thread is started and based on the keep-alive mechanism of the target thread, so as to determine that the thread of the application program can be correctly executed after modification.

Further, determining the running state of the target thread based on the CPU occupation time after the target thread is started includes: and under the condition that the CPU occupation time after the target thread is started is within the set threshold value range, determining that the target thread runs normally.

For example, the first terminal may analyze the CPU occupation time of a certain thread for a period of time, such as 5 minutes after the thread starts. If the CPU occupation time of the thread is between [ α1, α2], for example, α1=5%, and α2=65%, within 5 minutes, the thread is considered to be running normally, and the application is executed correctly.

Further, determining the operating state of the target thread based on the keep-alive mechanism of the target thread includes: and under the condition that the heartbeat signal sent by the target thread is received, determining that the target thread runs normally.

For example, if the thread needs to feed the dog at intervals, the embedded operating system of the first terminal judges that the thread sends a heartbeat signal (or called dog feeding information), the thread is considered to run normally, and the application program is executed correctly.

The first terminal determines the running state of the target thread based on the CPU occupation time after the target thread is started and/or based on the keep-alive mechanism of the target thread, so that the thread of the application program can be correctly executed after modification.

In other aspects of the embodiments of the present invention, referring to fig. 9, step106, after the step of determining the running state of the target thread based on the CPU occupation time after the target thread is started and/or based on the keep-alive mechanism of the target thread, further includes:

step 107, the priorities of all threads and the time slices of all threads of the adjusted application program are stored in the application registry.

And 108, performing integrity protection on the application registry to generate an integrity check value.

And step 109, storing the application registry under the condition that the integrity check value passes verification, so that the application program runs the threads directly by using the priorities of all threads of the application program after adjustment and the time slices of all threads when running next time.

The first terminal rewrites the priority levels of all threads and the time slices of all threads of the adjusted application program into an application registry, performs integrity protection on the application registry, and generates an integrity check value. Wherein the application registry information includes thread information of the application program, the thread information including thread name, thread priority, thread entry function, thread time slice, and the like. The integrity check value generation method may use a HASH algorithm, such as SHA1, SHA256, SM3 algorithm, etc. After the embedded operating system of the first terminal verifies the check value, the application registry information is stored in the nonvolatile memory. When the first terminal is restarted or powered down, and the embedded operating system of the first terminal runs again, the thread is directly run by using the new thread priority and the thread time slice in the application registry, so that the thread analysis running time is saved.

In other aspects of embodiments of the present invention, the application installation file further includes a signature value, the signature value being derived based on the integrity protection and/or the source legitimacy protection of the second terminal. Wherein the integrity protection may use HASH algorithms such as SHA1, SHA256, SM3 algorithms, etc.; the source legitimacy protection can use signature methods, such as RSA, ECC, SM, asymmetric algorithm signature, AES, DES, SM, and other symmetric algorithm signatures.

Referring to fig. 10, after step 101, the step of receiving the application installation file sent by the second terminal further includes:

step 102, performing integrity verification on the signature value and/or performing source validity verification.

Specifically, referring to fig. 11, after receiving the application installation file, the first terminal analyzes the application code by an application installer in the embedded system of the first terminal, and analyzes whether the application installation file has a signature value. If the signature value exists, the integrity and source legitimacy of the signature value is verified by using a security module prior to writing the verification signature and integrity verification key value by an administrator; if the problem is not found, the analysis is continued, and if the problem is found, the application installation is exited. The security module may be in the form of a security chip or a security module, or may be in the form of software of a security APP on an embedded operating system.

The embodiment of the invention realizes the security verification of the application program installation file by carrying out the integrity verification on the signature value and/or carrying out the source validity verification.

On the other hand, the embodiment of the invention also provides a thread information adjusting method which is applied to the second terminal. The second terminal may be various terminals that can add information to the application download file, for example, the second terminal may be a server.

The second terminal constructs an application installation file based on the application download file and the addition information. The priority reference value is a thread priority minimum value set or specified by the second terminal for the application program corresponding to the application program downloading file. The priority dynamic range value is a maximum range value that increases on the basis of the priority reference value. Wherein, different application programs can be classified and graded, and the thread priority reference value and the priority dynamic range of each application program are set. For example, when the importance level of the application 1 is higher than that of the application 2, and the importance level is higher as the priority is lower, the priority reference value of the thread of the application 1 is set to 10, and the priority dynamic range value is set to 10; the priority reference value of the thread of the application 2 is 20 and the priority dynamic range value is 10.

Step 202, sending the application program installation file to a first terminal, so that the first terminal can adjust thread information based on the application program installation file.

Wherein the signature value is obtained based on the integrity protection and/or the source legitimacy protection of the second terminal. Specifically, the second terminal may be obtained by performing integrity protection and/or source validity protection on the signature value through the encryptor. Wherein the integrity protection may use HASH algorithms such as SHA1, SHA256, SM3 algorithms, etc.; the source legitimacy protection can use signature methods, such as RSA, ECC, SM, asymmetric algorithm signature, AES, DES, SM, and other symmetric algorithm signatures.
