Detailed Description

In the embodiments of the present application, terms such as "first" and "second" are used to distinguish the same or similar items having substantially the same function and action. For example, the first chip and the second chip are only used for distinguishing different chips, and the sequence order thereof is not limited. Those skilled in the art will appreciate that the terms "first," "second," etc. do not denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance.

It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the embodiments of the present application, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple.

With the popularization of electronic devices, users can mount a Secure Digital (SD) memory card on the electronic device, so that the electronic device can use the SD memory card to store data; however, when the electronic device uses an abnormal SD memory card (hereinafter referred to as an SD card), a process of the electronic device storing data in the SD card or a process of the electronic device reading data of the SD card may be caused to have a problem of malfunction.

For example, fig. 1 is a schematic diagram of a failure problem provided by an embodiment of the present application, and as shown in fig. 1, the failure problems that may occur in an electronic device include read-write speed abnormality, read-write frequent error, data inability to be written, and data retention abnormality, where a proportion of the read-write speed abnormality in the failure problem is 10%, a proportion of the read-write frequent error in the failure problem is 20%, a proportion of the data inability to be written in the failure problem is 20%, and a proportion of the data retention abnormality in the failure problem is 50%.

The abnormal read-write speed may be understood as that the electronic device reads data from the SD card at a slow rate, or the electronic device stores data into the SD card at a slow speed, compared with the electronic device using a normal SD card. For example, when the electronic device uses a normal SD card and the CLASS of the normal SD card is 10, the read/write speed may be 10M/s, that is, the electronic device may read or write 10M data per second, whereas when the electronic device uses an abnormal SD card, 7M data per second may be read or written.

The frequent reading and writing errors can be understood as that when the electronic device reads data in the SD card or when the electronic device stores data in the SD card, the electronic device displays reading and writing errors.

The data cannot be written in the electronic device, which is understood to mean that the electronic device cannot store data into the SD card although the SD card is mounted on the electronic device.

The data storage exception may be understood as that, although the electronic device stores data into the SD card, when the electronic device reads the data from the SD card, the format of the read data may be changed, so that the electronic device cannot correctly use the data.

The abnormal SD card may include an external inferior SD card or an old SD card, and the external inferior SD card may be understood as the SD card having a defect on the outside, and the old SD card may be understood as the electronic device having a slow speed of reading data in the SD card.

As can be seen from the above, the electronic device may have a failure problem due to the abnormal SD card, which may cause the electronic device to have a card pause, a black screen, or a restart problem.

In general understanding, the problem of the electronic device can be solved by replacing the SD card, but when the electronic device has the problems of card pause, black screen or restart at each time, on one hand, the time of the user is wasted by the above frequent replacement of the SD card, and on the other hand, the problems of card pause, black screen or restart cannot be caused after the electronic device is replaced with the SD card, which affects the user experience of the electronic device.

Based on this, the reason why the electronic device has problems of stuck, black screen or restart every time is further analyzed in the embodiment of the present application is: after the SD card is inserted into the electronic equipment, the electronic equipment calls a File System Check (FSCK) program, the FSCK program needs to check and verify the legality and the consistency of the disk metadata of the SD card, and the disk metadata of the SD card can be abnormal due to the fact that the abnormal SD card is mounted on the electronic equipment and the electronic equipment frequently uses the abnormal SD card, so that when the disk metadata of the SD card is read into a memory of the electronic equipment by the FSCK program, the disk metadata of the SD card can be circularly loaded by the FSCK program, and further, the process of reading the disk metadata of the SD card by the FSCK program is a dead-cycle process; moreover, because the FSCK program is started by an initialization process (init process), the authority and priority of the FSCK program are high, and even if the memory usage is large, the FSCK program is not killed by a low memory killer (low memory killer), so that the memory usage of the electronic device is too large, the electronic device has the problems of jamming, black screen or restarting and the like, and further, the system crash of the electronic device is caused.

The abnormal disk metadata of the SD card can be understood as that the metadata of the file system in the SD card is damaged, which causes the metadata to be inconsistent with the format of the file system, so that when the electronic device calls the FSCK program to check and verify the validity and consistency of the SD card disk metadata, the electronic device cannot mount the SD card in a proper directory, and the electronic device can report an error; alternatively, even if the SD card is mounted on the electronic device, the file directory of the SD card displayed on the electronic device is scrambled, so that the electronic device cannot store data in the SD card, or the electronic device cannot read data in the SD card.

In view of this, according to the method of the embodiment of the present application, after it is confirmed that the SD card is inserted into the electronic device, when the electronic device performs FSCK on data of the SD card through the sub-process, the electronic device may monitor the operation of the sub-process in the main process, so as to know the operation of the sub-process in time, and further, when it is determined that the operation of the sub-process meets the preset condition, the electronic device may stop the sub-process, so as to avoid the problems of stutter, black screen, or restart of the electronic device due to the excessively large memory occupation, further avoid system crash of the electronic device in time, thereby enhancing the robustness of starting and operating the electronic device, so that the usability of the whole electronic device is not affected by the SD card, and the user does not need to frequently replace the SD card, thereby improving the use experience of the user on the electronic.

The method of the embodiment of the application can be applied to electronic equipment, as well as embedded equipment such as android (android) flat equipment and android televisions, and an SD card can be inserted into the embedded equipment, so that the embedded equipment can store data in the SD card, or the embedded equipment can read the data in the SD card; it can be understood that the specific content of the embedded device may also be set according to an actual application scenario, and the embodiment of the present application is not limited.

For example, the SD card scanning processing program may be mmc _ rescan, which is a function that can be used to detect relevant information of the SD card inserted into the electronic device, such as the type of the SD card, the data structure of the SD card, the capacity of the SD card, or the access rate supported by the SD card; it can be understood that specific contents of the related information of the SD card may also be set according to an actual application scenario, and the embodiment of the present application is not limited.

It should be noted that, with reference to fig. 2, when it is confirmed that the SD card is inserted into the electronic device, the electronic device may supply power to the SD card based on the power management module 141, so that the SD card may operate.

S403: and the electronic equipment reports the event that the SD card is inserted into the electronic equipment to the system layer through the kernel layer.

Accordingly, the system layer may know an event that the SD card has been inserted into the electronic device, and further, the electronic device may perform S404.

S404: the electronic equipment starting subprocess performs File System Check (FSCK) on the data of the SD card.

In the embodiment of the application, the data of the SD card refers to the disk metadata of the SD card, and before the electronic equipment mounts the SD card, the electronic equipment needs to check the legality and consistency of the disk metadata of the SD card, so that the electronic equipment performs FSCK on the disk metadata of the SD card by a sub-process; the electronic device may create a sub-process for executing the FSCK through a fork function, so that the electronic device may determine whether to kill the sub-process based on the running of the sub-process; moreover, the sub-process does not affect the main process, and the sub-process and the main process are asynchronously executed processes.

Based on the embodiment shown in fig. 4, exemplarily, fig. 5 is a schematic flowchart of a system exception handling method provided in the embodiment of the present application, and as shown in fig. 5, the method may include the following steps:

s501: the electronic device detects an interrupt report on the secure digital memory card SD card insertion at the kernel layer.

In the embodiment of the present application, referring to fig. 2, since there is a multimedia-media-block (mmcblk) driver in the core layer, the electronic device may detect an interrupt report about the insertion of the secure digital memory card SD card through the mmcblk driver in the core layer. For example, the mmcblk driver includes a driver, and the driver can recognize a read/write request of the SD card, so that the electronic device can detect an interrupt report about the SD card insertion of the secure digital memory card according to the read/write request.

It can be understood that a specific implementation manner of the electronic device detecting the interrupt report related to the secure digital memory card SD card insertion at the kernel layer may also be set according to an actual application scenario, and the embodiment of the present application is not limited.

S502: and the electronic equipment scans a user space event Uevent interface of the kernel layer to confirm that the SD card is inserted into the electronic equipment.

S503: and the electronic equipment reports the event that the SD card is inserted into the electronic equipment to the system layer through the kernel layer.

In this embodiment, referring to fig. 2, because the mmcblk driver is located in the kernel layer, and the disk daemon (volume daemon, vold) is located in the system layer, according to S502, the electronic device scans and confirms that the SD card is inserted into the electronic device at the Uevent interface, and further, the electronic device may report an event that the SD card is inserted into the electronic device to the vold of the system layer through the Uevent interface, and accordingly, the vold of the system layer may obtain the event that the SD card is inserted into the electronic device.

It can be understood that the specific implementation manner of the event that the SD card is inserted into the electronic device is reported to the system layer by the electronic device through the kernel layer, and may also be set according to an actual application scenario, and the embodiment of the present application is not limited.

S504: the electronic equipment starting subprocess performs File System Check (FSCK) on the data of the SD card.

S505: the electronic device monitors the sub-process in the main process.

S506: and when the running time of the sub-process is greater than or equal to a first value and/or the memory occupation ratio of the electronic equipment in the running of the sub-process is greater than or equal to a second value, the electronic equipment stops the sub-process.

In the embodiment of the application, the electronic device can know the running of the sub-process in time by executing the step S505, so that the electronic device can stop the sub-process based on the running of the sub-process; the running of the sub-process may include a running time of the sub-process or a memory occupation ratio of the electronic device during running of the sub-process, and the memory occupation ratio of the electronic device during running of the sub-process may be understood as a ratio of a memory in the electronic device and a running memory of the electronic device, which is applied for running the sub-process.

In one possible implementation manner, the electronic device stops the sub-process when the running time of the sub-process is judged to be greater than or equal to the first value. For example, when the running time of the sub-process is 110 seconds and the first value is 60 seconds, the electronic device may stop the sub-process since 110 seconds >60 seconds.

In another possible implementation manner, when the electronic device determines that the running time of the sub-process is smaller than a first value, the electronic device determines whether a memory occupation ratio of the electronic device in the running of the sub-process is larger than or equal to a second value; and when the memory occupation ratio of the electronic equipment is greater than or equal to the second value in the running of the subprocess, the electronic equipment stops the subprocess.

For example, when the running time of the sub-process is 40 seconds, the first value is 60 seconds, the electronic device further determines the memory usage ratio of the electronic device during the running of the sub-process because 40 seconds is less than 60 seconds, and when the second value is 40% and the memory usage ratio of the electronic device during the running of the sub-process is 55%, the electronic device may stop the sub-process because 55% > 40%.

The electronic equipment can call a kill (kill) fsck subprocess, and then the electronic equipment stops the subprocess through the kill fsck subprocess; it can be understood that the implementation manner of the electronic device stopping the sub-process may also be set according to an actual application scenario, and the embodiment of the present application is not limited.

Wherein the electronic device may set the first and second values described above based on the historical data; the historical data comprises the running time of the plurality of sub-processes and the memory occupation proportion of the electronic equipment in the running of the plurality of sub-processes. For example, the first value may be an average value of the running times of the plurality of sub-processes, or may be the running time of one of the sub-processes; the second value may be an average value of memory occupation ratios of the electronic device in the running of a plurality of sub-processes, or may be a memory occupation ratio of the electronic device in the running of one sub-process; it can be understood that the specific value of the first value and the specific value of the second value may also be set according to an actual application scenario, and the embodiment of the present application is not limited.

S507: and when the memory occupation ratio of the electronic equipment is smaller than the second value in the running of the subprocess, the electronic equipment waits for the preset time length and then judges whether the running time of the subprocess is larger than or equal to the first value again.

In this embodiment of the application, the preset time may be 1 second, so that the electronic device may determine whether the running time of the sub-process is greater than or equal to the first value again after 1 second, and when the electronic device determines that the running time of the sub-process is greater than or equal to the first value, the electronic device may refer to the content adaptation description of S506, which is not described herein again.

It can be understood that the specific value of the preset time may also be set according to an actual application scenario, and the embodiment of the present application is not limited.

S508: and the electronic equipment displays a user interface, wherein the user interface comprises information for prompting the SD card to operate abnormally.

In this embodiment of the present application, the information about the abnormal operation of the SD card may include that the SD card is an abnormal SD, and may also include that metadata of a disk in the SD card is damaged, and it can be understood that specific contents of the information about the abnormal operation of the SD card may also be set according to an actual application scenario, and this embodiment of the present application is not limited.

In the embodiment of the application, a User Interface (UI) may include a notification popup window or a drop-down bar, and when the UI includes the notification popup window, information for prompting the SD card to operate abnormally may be displayed in the notification popup window, so that a user may see the information that the SD card operates abnormally; or, when the user interface comprises the pull-down bar, the user triggers the pull-down bar, and the pull-down bar is used for displaying information for prompting the abnormal operation of the SD card according to the triggering of the user, so that the user can know that the SD card operates abnormally.

It should be noted that, because the electronic device includes a plug-in for creating a page reminder and a status prompt bar, for example, a notify plug-in, the electronic device may display the UI through the notify plug-in, so as to display information about abnormal operation of the SD card, and further prompt the user that the SD card is abnormal in operation, so that the user may replace the SD card, or the user may perform formatting processing and the like on the SD card on the electronic device.

Taking an electronic device as an example of a terminal device, for example, fig. 6 is a schematic diagram of a drop-down box provided in an embodiment of the present application, where when a user triggers the drop-down box on the terminal device, information for prompting an SD card to operate abnormally may be displayed on the drop-down box, for example, the SD card is abnormal, and the drop-down box also displays content that may cause file loss due to continuous use and suggests that you replace the SD card with backup data, so that the user may replace the SD card according to the content, or the user may format the SD card on the terminal device according to the content, so that the terminal device may continue to use the SD card, thereby expanding a data storage space of the electronic device and improving user experience.

With reference to the embodiments shown in fig. 4 or fig. 5, for example, fig. 7 is a schematic flowchart of an electronic device mounting an SD card according to an embodiment of the present disclosure, as shown in fig. 7, when an interrupt report about SD card insertion is detected by an mmcblk driver after the SD card is inserted into the electronic device, the electronic device scans that the SD card is inserted into the electronic device at a Uevent interface, so that the electronic device can report an event that the SD card is inserted into the electronic device to a vold through the Uevent interface, and when the vold does not respond to the SD card normally, the electronic device can determine that the SD card inserted into the electronic device is an abnormal SD card, and therefore, the electronic device does not mount the SD card, so that the electronic device cannot use the SD card; when the response of the vold to the SD card is normal, the electronic device may perform FSCK on the data of the SD card, and in the FSCK process of the electronic device, if the electronic device is stuck, blacked or restarted, the data in the SD card may be abnormal, for example, the format of the data of the SD card is abnormal, so that the electronic device cannot mount the SD card in a proper directory, and therefore the electronic device does not mount the SD card; if the electronic equipment does not have the conditions of card pause, black screen, restart and the like, the electronic equipment can mount the SD card, so that the electronic equipment can use the SD card to store data, the data storage space of the electronic equipment can be expanded, and the use experience of a user is improved.

When the electronic device is stuck, blacked or restarted, the memory occupied by the electronic device running the FSCK may be too large, so that on the basis of the embodiment shown in fig. 7, a sub-process may be created, and the memory of the electronic device is prevented from being too large according to the running of the sub-process, thereby preventing the electronic device from being stuck, blacked or restarted, and further preventing the system of the electronic device from being crashed.

Exemplarily, fig. 8 is a schematic flowchart of a system exception handling provided by an embodiment of the present application, where the method in the embodiment of the present application is used in a process in which an electronic device in fig. 7 performs FSCK on data in an SD card, as shown in fig. 8, the electronic device creates a sub-process, and since different file systems need to call different FSCK, the electronic device may call doCheck () to detect a file system in the SD card, when the file system is EXT4, the electronic device may start FSCK corresponding to EXT4, when the file system is FAT, the electronic device may start FSCK corresponding to FAT, and further, the electronic device may perform FSCK on data in the SD card; and when the electronic equipment performs FSCK on the data in the SD card in the subprocess, the electronic equipment can monitor the running time of the subprocess and the memory occupation ratio of the electronic equipment in the running of the subprocess in the main process, so that the electronic equipment can determine whether to stop the subprocess according to the running time of the subprocess and the memory occupation ratio of the electronic equipment in the running of the subprocess.

In one example, when the running time of the sub-process is greater than or equal to 60 seconds, the electronic device calls a kill fsck sub-process, and the sub-process is stopped through the kill fsck sub-process; or, when the running time of the sub-process is not greater than or equal to 60 seconds, that is, the running time of the sub-process is less than 60 seconds, the electronic device may call the kill fsck sub-process and stop the sub-process through the kill fsck sub-process under the condition that the memory occupation ratio of the electronic device in the running of the sub-process is greater than or equal to 40%.

Therefore, after the electronic equipment stops the subprocess, the electronic equipment can display the UI, and the information of the SD card running abnormity is displayed through the UI interface, so that a user can be prompted to replace the SD card, or the user is prompted to perform formatting processing on the SD card.

For another example, when the running time of the sub-process is not greater than or equal to 60 seconds, that is, the running time of the sub-process is less than 60 seconds, the electronic device may wait for 1 second when the memory occupied proportion of the electronic device in the running of the sub-process is not greater than or equal to 40%, that is, the memory occupied proportion of the electronic device in the running of the sub-process is less than 40%, and determine again whether the running time of the sub-process is greater than or equal to 60 seconds after 1 second, so that the electronic device repeatedly executes the determination process, so that the determination result of the electronic device is not affected by the external network environment, and the accuracy of the determination result is improved.

It should be noted that, with reference to fig. 7, in the flowchart shown in fig. 8, after performing FSCK on data of the SD card, the electronic device may perform corresponding steps based on a determination result of the host process, which is not described herein again.

In the flowchart shown in fig. 8, with reference to fig. 7, when the electronic device displays a UI to prompt the user to replace the SD card, or after prompting the user to perform a formatting process on the SD card, the electronic device executes the step of not mounting the SD card in fig. 7.
