Therefore, the existing complete memory data transfer scheme cannot dynamically adapt to memories with different storage capacities, so that waste of storage space is easily caused, or transfer of complete memory data cannot be normally executed, so that faults of intelligent terminal equipment cannot be repaired in time, and use experience of users is affected.

The following embodiments and features of the embodiments may be combined with each other without conflict.

When a complete machine failure occurs in an intelligent terminal device, such as a smart phone, a personal computer, etc., in order to analyze the failure cause and locate the failure, a Dump flow is executed, including: and loading a fault processing system, and acquiring and storing dump data (namely fault diagnosis data), wherein the dump data comprises memory RAM data, the full memory data is Fulldump data, and the Fulldump data can be Fulldump logs and comprise complete memory information. In the Dump flow, there are two data saving paths, the first one is not to automatically save Dump data, and other electronic devices such as a computer end need to save the Dump data by using a QPST (Qualcomm Product Support Tool, transmission software developed for a high-pass chip) tool, so that the Dump data cannot be saved in time due to the precondition that the Dump data is saved in full memory; the second type of method automatically transfers the Fulldump data to a rawdump (original transfer data) partition of the physical storage device, so that the usable storage space of the physical storage device is reduced, and the Fulldump data cannot be recovered conveniently and cannot meet the user requirements of the test device. In addition, the analysis of the overall stability problem of the intelligent terminal device is strongly dependent on the Fulldump log, so that a Fulldump transfer scheme is provided for the problem that the Fulldump log cannot be conveniently extracted and the pain point of the user use requirement is tested.

The Fulldump transfer scheme reserves a fixed size of storage space at the tail of a data partition available to a user of the physical storage device, for storing the Fulldump log. The Fulldump transfer scheme can be applied to terminal devices with different memory capacity specifications of Double Data Rate (DDR) devices. The Fulldump transfer scheme is terminal equipment adapting to memory capacity specifications of different DDR devices, meets the memory capacity specification of the maximum DDR device of the terminal equipment at the moment, is designed to be downward compatible, and the reserved memory space is the memory capacity of the maximum DDR device of the terminal equipment. However, the Fulldump transfer scheme thus designed has the following problems: for terminal equipment with the memory capacity specification of the DDR device smaller than the preset maximum capacity specification, a large amount of storage space on the physical storage equipment is wasted, so that available data partitions of users are reduced, the scheme is not applicable, and resources are wasted to influence user experience; the Fulldump transfer scheme starts to preset the possible maximum DDR device memory capacity specification, and because the preset memory capacity specification is static and invariable, if the new DDR device memory capacity specification is designed by a new product and exceeds the preset memory capacity specification, the scheme adaptation problem will be caused, the Fulldump transfer scheme is invalid, so that the fault of the intelligent terminal device cannot be repaired in time, and the use experience of the user is affected.

In order to reduce repeated manpower work in the adapting process of the Fulldump transfer scheme and compatibility and resource waste problems existing in the scheme, the embodiment of the application provides a storage space configuration method, which can adapt memories with different storage capacities, avoid the waste of storage space, ensure normal execution of transfer of complete memory data and timely repair faults of intelligent terminal equipment. For details of the storage space configuration method, reference may be made to the descriptions in the various embodiments below.

In order to better understand the storage space configuration method provided by the embodiment of the present application, an application scenario of the storage space configuration method provided by the embodiment of the present application is described below with reference to fig. 1A and fig. 1B.

Referring to fig. 1A, the storage device of the terminal device is a universal flash memory (Universal Flash Storage, UFS), and the storage capacity of the storage device is 128G. If the preset maximum memory capacity of the DDR device is 12G, the capacity of the reserved memory space for storing Fulldump data of the memory device is 12G. If the DDR device memory capacity is 4G, the DDR device memory capacity is smaller than the preset maximum memory capacity and the reserved memory space capacity of the memory device. When the terminal equipment fails, the capacity of the Fulldump data is 4G, after the Fulldump data is transferred to the reserved storage space of the storage equipment, the reserved storage space still has the free storage space with the capacity of 8G, and the free storage space can not store other data, so that the storage space with the capacity of 8G of the storage equipment is wasted.

Referring to fig. 1B, the storage device of the terminal device is a general flash memory, and the storage capacity of the storage device is 128G. If the preset maximum memory capacity of the DDR device is 12G, the capacity of the reserved memory space for storing Fulldump data of the memory device is 12G. If the memory capacity of the new DDR device designed by the new product is 16G, the memory capacity of the new DDR device is larger than the preset maximum memory capacity and the reserved memory space of the memory device. When the terminal equipment fails, the Fulldump data capacity is 16G, and exceeds the capacity of the reserved storage space, so that the terminal equipment cannot be repaired in time, and the use experience of a user is affected.

The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc. The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture. The telephony manager is for providing communication functions of the electronic device. Such as the management of call status (including on, hung-up, etc.). The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like. The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

Android run time includes a core library and virtual machines. Android run time is responsible for scheduling and management of the Android system. The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. Such as surface manager (surface manager), media library (Media Libraries), three-dimensional graphics processing library (e.g., openGL ES), 2D graphics engine (e.g., SGL), etc.

Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio and video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc. The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like. The 2D graphics engine is a drawing engine for 2D drawing.

The hardware abstraction layer runs in the user space, encapsulates the kernel layer driver and provides a calling interface for the upper layer.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

The kernel layer is the core of the operating system of the electronic device, is the first layer of software expansion based on hardware, provides the most basic function of the operating system, is the basis of the operating system, is responsible for managing the processes, the memory, the device driver, the files and the network system of the system, and determines the performance and the stability of the system. For example, the kernel may determine the time an application is operating on a certain portion of hardware.
