Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, but not all of them. Based on the embodiments in the present application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present application.

The storage space management method provided in the embodiment of the present application may be implemented by a software algorithm. The algorithm corresponding to the method can be preset in the processor of the target device. The target device may be any one of smart phones, tablet computers, smart bracelets, smart refrigerators and other types of electronic devices.

In one embodiment, as shown in FIG. 1, the process steps implemented by the storage space management method are as follows:

Step 102, when the target device is turned on for the first time, read the preset management instructions in the specified partition.

In this embodiment, the management instruction is saved in a designated partition of the target device in advance. When the target device is turned on, the management instruction is read from the instruction partition. Wherein, the specified partition may be any storage partition in the memory of the target device, for example, the specified partition may be a miscellaneous (mics) partition.

In this embodiment, the management instruction can be converted into ASCII ciphertext in advance, and the translated ciphertext can be written into the image to be upgraded by the misc partition through a software tool, so as to be used in the subsequent storage space management method of the target device. A mics partition format is shown in FIG. 2 , in which management instructions are written in hexadecimal, and numbers and letters in FIG. 2 represent hexadecimal numbers.

In this embodiment, the management instruction in the misc partition can be read through the preset Read From Partition function.

In one embodiment, after the target device is turned on for the first time, but before reading the preset management command in the specified partition, the recovery environment of the target device is initialized, so that the target device can execute the restart recovery command. For example, when an electronic device based on the Linux system (Linux system is a UNIX-like operating system that is freely used and freely disseminated) is turned on, it first enters the preparation stage for starting the device, that is, the Unified Extensible Firmware Interface (Unified Extensible Firmware Interface, referred to as UEFI) stage, and then after entering the Linux system, the initialization (Init) process begins. Initializing the recovery (recovery) environment of the target device is realized during the initialization process.

Step 104, obtain the current storage space size of the memory in the target device through the management instruction.

In this embodiment, the preset management instruction is used to obtain the current storage space size of the memory in the target device. That is, after the target device is turned on and before the user uses it, the current storage space size is first obtained, so that the target device can be used normally.

In this embodiment, the memory in the target device can be Embedded Multi Media Card (EMMC for short), Universal Flash Storage (UFS for short), and any other type of memory that can implement this method. The protection scope of the application is not limited by the specific type of memory.

In one embodiment, the management instructions include restart recovery instructions, erase instructions and partition alignment instructions. Obtain the storage space size of the memory in the target device through the management command. The specific implementation process is as follows: save the erase command and partition alignment command into the buffer control block; restart the target device according to the restart recovery command, and read the buffer control block Erase instruction and partition alignment instruction in; according to the erase instruction, delete the original storage space size in the software data; according to the partition alignment instruction, obtain the current storage space size of the memory in the target device.

In this embodiment, a buffer control block (Buffer Control Block, BCB for short) is a storage block capable of storing instruction data. After the target device reads the management command, it first saves the erase command and the partition alignment command in the BCB, and then enters the recovery environment after rebooting through the boot-recovery command. In the recovery environment after reboot, read the erase command and partition alignment command in BCB again. Then delete the original storage space size in the software data according to the erasing instruction. Then according to the partition alignment instruction, the current storage space size of the memory in the target device is acquired.

In one embodiment, after deleting the original storage space size in the software data according to the erase instruction, before obtaining the current storage space size of the memory in the target device according to the partition alignment instruction, delete the erase instruction stored in the buffer control block. According to the partition alignment instruction, after obtaining the current storage space size of the memory in the target device, before updating the current storage space size to the software data required for the target device to run, delete the partition alignment instruction stored in the buffer control block.

In this embodiment, when the erase instruction stored in the BCB is executed, the erase instruction in the BCB is immediately deleted; when the partition alignment instruction stored in the BCB is executed, the partition alignment instruction in the BCB is immediately deleted to ensure that the partition alignment instruction in the BCB is executed. The erase instruction and partition alignment instruction are only used once, avoiding the process of repeatedly executing instructions.

In one embodiment, after obtaining the current storage space size of the memory in the target device through the management instruction, the preset management instruction in the specified partition is deleted.

In this embodiment, after the target device enters the use stage, the memory of the target device is fixed and will not change at any time. Therefore, the storage space management process for the target device only needs to be performed once, and the target device does not need to repeatedly execute the process. After the current storage space size of the memory in the target device is obtained, the preset management command in the specified partition is deleted, and when the target device is turned on again, the storage space management process will not be started again through the management command. Avoid the boot delay that occurs when the storage space is managed every time the boot is started, and improve the user experience.

In one embodiment, the memory includes at least one storage partition. According to the partition alignment instruction, obtain the current storage space size of the memory in the target device. The specific process is: according to the partition alignment instruction, obtain the partition storage space size corresponding to at least one storage partition that can be used by the user; The sum is used as the current storage space size of the memory in the target device.

In this embodiment, partition alignment means reasonable boundary alignment between the partition and the memory. Through the process of partition alignment, it is possible to accurately know the partition storage space size corresponding to each storage partition that can be used by users, such as the size of user data (userdata) or the size of cache (cache). Through the storage space size of each partition, a more accurate current storage space size available to the user can be obtained, paving the way for the normal operation of the target device.

In this embodiment, the partition alignment function can be enabled by enabling the partition alignment (ALIGN_PARTITIONS_TO_PERFORMANCE_BOUNDARY) feature. When the ALIGN_PARTITIONS_TO_PERFORMANCE_BOUNDARY feature is enabled, the target device will automatically align all partitions and recalculate the userdate size after the device is restored to factory settings.

Step 106, updating the current storage space size into the software data required for the target device to run.

In this embodiment, after the current storage space size is obtained, the current storage space size is updated to the software data required for the target device to run, so that the target device starts running based on the current storage space size. That is, the target device has completed the self-adaptation of the storage space.

In one embodiment, after the current storage space size is saved in the software data required for the target device to run, the target device is restarted so that the target device can be used normally.

In this embodiment, the target device automatically completes the process of rebooting the target device, which can avoid the problem of poor user experience caused by manual operation by the user, and make the target device more intelligent.

In the storage space management method provided by this application, when the target device is turned on for the first time, it reads the preset management command in the specified partition, obtains the current storage space size of the memory in the target device through the management command, and updates the current storage space size to In the software data required for the target device to run. That is to say, when the target device is turned on for the first time, the current storage space size of the target device memory is obtained through management instructions, and then the operation of the target device is realized based on the current storage space size, rather than through the previously written storage space. The size of the space to run the software. When the software data runs on another new device with a different size of the current storage space, the method can adapt to the storage space instead of redeveloping the software data for the new device. By adapting to the current storage space of the target device, the process of adapting a set of software data to multiple hardware devices is realized, which greatly reduces the development difficulty of developers and improves development efficiency.
