[0022] In the prior art, when performing a system stability test on an intelligent terminal device, some systems in the communication processor may have stability problems, which may cause these systems to become abnormal. By dumping the memory information of the system where the abnormality occurs, the cause of the abnormality can be located. However, when an abnormality occurs, the system may not be able to dump its corresponding memory information, which may result in the inability to locate the cause of the abnormality.
[0023] In the embodiment of the present invention, when it is determined to perform a transfer operation on the memory information of the target system, the already stored memory information of the target system is obtained from the kernel, and the memory information of the target system is stored in a preset storage space. The transfer of the memory information of the target system is implemented by the application processor, so when a failure occurs in the target system, the memory information of the target system can be normally transferred.
[0024] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0025] In a specific implementation, the data transfer method provided in the following steps 101 to 103 may be executed by an application processor (AP) having a data processing function in the smart terminal device.
[0026] In the following embodiments, unless otherwise stated, the "system" may refer to a hardware system in a communication processor. Specifically, the "system" described in the following embodiments may include a modem system, a sensor system, a positioning system, and the like.
[0027] The embodiment of the present invention provides a data transfer method, referring to Figure 1 , the following is a detailed description through specific steps.
[0028] In the embodiment of the present invention, the following data transfer method can be regarded as a software system, and the software system can be run by an application processor (AP) in the intelligent terminal device. In other words, the following data transfer method is run in the application processor.
[0029] Step 101, determining to perform a transfer operation on the memory information of the target system.
[0030] In the embodiment of the present invention, the target system may be any system in the communication processor. The number of the target systems may be one or more.
[0031] In a specific implementation, the terminal device can detect whether to trigger the transfer operation of the memory information of the target system. When it is detected that the transfer operation of the memory information of the target system is triggered, the following step 102 can be executed.
[0032] In some embodiments, the tester can interact with the shell and input a transfer instruction through the human-machine input interface of the intelligent terminal device, and the transfer instruction can include the identification information of the target system. When the transfer instruction is received, it can be determined to trigger the transfer operation of the memory information of the target system.
[0033] In other embodiments, when an abnormality is detected in a certain system, the system where the abnormality occurs can be determined to be a target system, thereby triggering a transfer operation of the memory information of the target system.
[0034] Step 102, obtaining memory information of the target system from the kernel.
[0035] In the embodiment of the present invention, the kernel may store memory information of at least one first system. The first system mentioned above is any system in the communication processor. The first system may include a target system.
[0036] That is to say, the memory information of multiple systems may be pre-stored in the kernel. When it is determined to perform a transfer operation on the memory information of the target system, the memory information of the target system may be obtained from the kernel.
[0037] In an embodiment of the present invention, a configuration file may be obtained in advance, and the obtained configuration file may be parsed. The configuration file may include memory information of at least one first system. Thus, by parsing the configuration file, the memory information of at least one first system may be obtained, and the memory information of at least one first system may be stored in the kernel.
[0038] In a specific implementation, after acquiring the memory information of the first system from the configuration information, the first device node corresponding to the first system may be write-locked, the memory information of the first system may be written into the kernel, and then the write lock of the first device node may be released.
[0039] In a specific implementation, a device node can be an interface between an application running in an application processor and a kernel driver. In a Linux system, a device node is a special file type located in the / dev directory. In a Linux system, all physical devices are abstracted as files, and the files of these hardware devices are represented by device nodes.
[0040] In a specific implementation, the steps of obtaining the configuration file and parsing the configuration file may be performed before step 102 , or may also be performed before step 101 .
[0041] In some embodiments, the tester may generate a configuration file in advance and store the configuration file before performing a system stability test on the smart terminal device. During the initialization phase of the stability test on the smart terminal device, the configuration file is read and parsed. The tester may configure the memory information of the first system, the number of the first system, the identification information of the first system, etc. in the configuration file.
[0042] In some embodiments, the configuration file may be an Extensible Markup Language (XML) format file.
[0043] In a specific implementation, the XML parsing function can be implemented by calling the expat external library to parse the configuration file in XML format.
[0044] In an embodiment of the present invention, when the memory information of the target system is obtained from the kernel, the target device node corresponding to the target system may be write-locked first. After that, the memory information number corresponding to the target system is set, the write lock on the target device node is released, and the target device node is opened. The target device node is read-locked, and the memory information corresponding to the target system is read from the memory based on the memory information number, and the read lock on the target device is released.
[0045] Step 103: transfer the memory information of the target system to a preset storage space.
[0046] In the embodiment of the present invention, a storage space may be preset, and the storage space may be an external storage space independent of the communication processor, or may be a storage space inside the communication processor.
[0047] After obtaining the memory information of the target system from the memory, the memory information of the target system can be transferred to the preset storage space. The tester can obtain the memory information of the target system from the preset storage space through shell interactive instructions.
[0048] In an embodiment of the present invention, a tester can input a shell instruction in a Linux operating system, and the shell instruction is a read instruction, and the read instruction can be used to read the memory information of the target system. After receiving the read instruction, the target device node can be read locked, and the memory information of the target system can be read from the kernel. After completing the reading of the memory information of the target system, the read lock of the target device node is released. After completing the reading of the memory information of the target system, the read memory information of the target system can be output, so that the tester can intuitively know the memory information of the target system, thereby improving the efficiency of locating the cause of the failure of the target system.
[0049] For example, the read instruction is used to read the memory information of the modem system. After receiving the read instruction, the target device node corresponding to the modem system is read locked. The memory information corresponding to the modem system is read, and after the reading is completed, the read lock of the target device node corresponding to the modem system is released.
[0050] In the embodiment of the present invention, the software system can be divided into a driving module, a parsing module and a debugging module according to functions.
[0051] Reference Figure 2 , a structural diagram of a software system in an embodiment of the present invention is given. The software system includes a driver module 201, a parsing module 202 and a debugging module 203. In some scenarios, the driver module 201 can be called a kernel state, and the parsing module 202 and the debugging module 203 can be called a user state.
[0052] In a specific implementation, the driver module 201 can expose the memory information of the first system to the debugging module 203 in the following directory: first device node / dev / cp_dump. The driver module 201 can implement read operations, write operations, close operations, input and output control operations, etc. on the first device node.
[0053] The above-mentioned parsing module 202 can be used to obtain and parse the configuration file, and store the memory information of the first system in the configuration file in the kernel.
[0054] The above-mentioned debugging module 203 can be coupled to the human-machine input interface of the intelligent terminal device, and then receive the shell command input by the tester, obtain the memory information of the target system, and transfer it to the preset storage space.
[0055] Therefore, the tester can use shell instructions to determine which target system or systems to select and transfer memory information; or, the tester can select the memory information of one or some target systems to facilitate the tester to locate the target system where the abnormality occurs and then determine the cause of the abnormality.
[0056] In summary, the memory information of the target system is transferred through the application processor, so when a failure occurs in the target system, the memory information of the target system can be transferred normally.
