Although various aspects of the embodiments are illustrated in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

In the related art, after the computing device crashes, a debugger is needed to acquire a drive log, so that the debugging difficulty is high, and the device is limited. The embodiment of the disclosure provides a function of reserving target physical memory through the BIOS, so that the drive log after the crash can be obtained without using the debugger, namely, the BIOS is started when the computer is started, the target physical memory can be reserved through the BIOS in response to the memory reservation instruction, and the target physical memory is used for storing the target drive log, so that the target drive log is dumped into a hard disk, the computer is simple to use and instant in use, the obtaining efficiency of the drive log is improved, the use threshold and the limitation of use scenes are reduced, and the computer can be used in various types of computing equipment.
In one exemplary application scenario, when the computing device is powered on, the computing device enters a power-on initialization procedure, in the power-on initialization procedure, the computing device starts a BIOS, the BIOS enters an initialization procedure, after the BIOS initialization procedure is completed, an operating system initialization procedure is performed, and after the operating system initialization procedure is completed, other initialization procedures such as a hardware and service initialization procedure are performed until the power-on initialization procedure is completed. In this exemplary application scenario, the embodiments of the present application may complete the steps of reserving the target physical memory by the BIOS and dumping the target drive log to the hard disk in the above-mentioned power-on initialization procedure.
In the following, taking the application scenario as an example, an exemplary embodiment is used to describe a method for detecting and analyzing a crash provided by an embodiment of the present disclosure.
Referring to fig. 1, a flowchart of a method for detecting and analyzing a crash according to an exemplary embodiment of the present disclosure is shown, where the method is used in a computing device for illustration. The method comprises the following steps.
Step 101, starting the BIOS when starting up.
The "power on" in step 101 may be, for example, normal manual power on, and may be a dead halt before power on, for example, after the computing device is forced to be powered off after dead halt, the step 101 may be entered; a dead halt may not occur, for example, the computing device is manually powered on again after normal shutdown, and step 101 may also be entered.
Optionally, the BIOS is stored in a Read Only Memory (ROM) that does not lose data after power-off. The BIOS, also known as a boot loader (English), includes programs for basic input and output of the computing device, a hardware self-test program after power-on, and an operating system self-start program. The BIOS is capable of reading basic boot information of the computing device from a complementary metal-Oxide-Semiconductor (CMOS). The primary functions of the BIOS include providing the lowest, most direct hardware settings and control for the computing device. In the disclosed embodiment, the BIOS provides the functionality to preserve the target physical memory.
Step 102, in response to the memory reservation instruction, reserving, by the BIOS, a target physical memory, where the target physical memory is used to store a target drive log, and the target drive log indicates a working state of the target drive before a crash.
The target physical memory may be a preset physical memory for storing the target drive log. Optionally, the target physical memory is set by default or is set by user. The embodiments of the present disclosure are not limited in this regard.
The memory reservation indication is an indication when the target identification indicates that the BIOS needs to reserve physical memory. Alternatively, the memory reservation indication may be indicated by a "target identifier", e.g. when a predetermined target identifier is read by the BIOS, the memory reservation indication may be considered to be obtained. The computing device, in response to the memory reservation indication, to reserve the target physical memory by the BIOS may include: the computing device reads a target identifier through the BIOS, wherein the target identifier is used for indicating whether the BIOS needs to reserve physical memory or not; when the target identifier indicates that the BIOS needs to reserve the physical memory, the target physical memory is reserved through the BIOS.
Optionally, the target identifier is stored in CMOS, and the computing device reads the target identifier through BIOS, including: the computing device reads the target identification from the CMOS through the BIOS.
Optionally, the method includes indicating that the BIOS needs to reserve physical memory when the target is identified as the first value, and indicating that the BIOS does not need to reserve physical memory when the target is identified as the second value. For example, the first value is 1 and the second value is 0. The embodiments of the present disclosure are not limited in this regard. Alternatively, the target identifier may be preset as required. Illustratively, the target identifier is set by default or is custom, e.g., the target identifier may be set to 1 in advance to perform step 102 by default.
In an exemplary application scenario, after a computing device is started and starts a BIOS, the BIOS enters an initialization flow, in the BIOS initialization flow, the computing device reads a target identifier through the BIOS, when the target identifier is 1, the BIOS acquires a memory reservation instruction, and the computing device responds to the memory reservation instruction and reserves a preset target physical memory through the BIOS, wherein the target physical memory is used for storing a target drive log.
According to the embodiment of the disclosure, the target identifier is set to indicate whether the BIOS needs to reserve the physical memory, so that the BIOS can determine whether the physical memory needs to be reserved by reading the target identifier, and the accuracy of memory reservation indication and timeliness of responding to the memory reservation indication are further ensured.
Optionally, the computing device may further submit the first physical memory to the kernel of the operating system through the BIOS, where the first physical memory is a physical memory that does not need to be reserved. That is, when the target identifier indicates that the BIOS needs to reserve the physical memory, the target physical memory is reserved by the BIOS, and other physical memories except for the target physical memory are submitted to the kernel of the operating system, where the first physical memory is other physical memories except for the target physical memory. When the target identifier indicates that the BIOS does not need to reserve the physical memory, submitting all the physical memory to the kernel of the operating system through the BIOS, wherein the first physical memory is all the physical memory in the case. According to the embodiment of the disclosure, the BIOS submits the first physical memory, namely the physical memory which does not need to be reserved, to the kernel of the operating system, so that the physical memory can be redistributed and utilized by the operating system, and the overall performance of the system is improved.
Step 103, the target drive log is dumped into the hard disk.
Through the above step 102, the BIOS reserves the target physical memory, and the computing device may dump the target drive log stored in the target physical memory into the hard disk, where the target drive log is a drive log automatically generated when the computing device crashes, and the target drive log includes the working state information of the target drive before the computing device crashes.
Optionally, the target driver is a driver of the target hardware device, and the target driver may be a driver of a video card, a driver of a sound card, a driver of a network card, and the like. The operating system communicates with the target hardware device through the target driver, for example, the operating system communicates with the graphics card through the driver of the graphics card.
Alternatively, the computing device may dump the target drive log into the hard disk by: loading a target drive after the initialization of the operating system is completed; when the target drive inquires that the reserved target physical memory exists in the BIOS, the target physical memory is obtained and mapped; and when the target drive detects that the target drive log exists in the target physical memory, dumping the target drive log into the hard disk.
In one example, after the target driver is loaded, the target driver queries the BIOS for the presence of reserved target physical memory, e.g., the target driver may query the BIOS for the presence of reserved target physical memory through an advanced configuration and power management interface (Advanced Configuration and Power Management Interface, ACPI). When the reserved target physical memory exists in the BIOS, the reserved target physical memory in the BIOS is obtained, the target physical memory is mapped to the virtual address space, and then whether a target drive log exists in the target physical memory is detected. For example, referring to the description of step 101, a target drive log may or may not be present in the target physical memory because an excessive crash may or may not occur prior to power-on. And when the target drive log exists in the target physical memory, dumping the target drive log into the hard disk. And when the fact that the target drive log does not exist in the target physical memory is detected, continuing the starting initialization flow of the computing equipment, and finishing the starting flow. And when the BIOS is queried that the reserved target physical memory does not exist, continuing the starting initialization flow of the computing equipment, and finishing the starting flow.
Through the steps, the computing device dumps the target drive log into the hard disk through the BIOS, and optionally, the computing device extracts the target drive log from the hard disk and performs detection analysis. This analysis can be done at any time as needed after the target drive log is dumped into the hard disk.
Optionally, the computing device performs detection analysis on the target drive log, including: the computing equipment screens target keywords in the target drive log, and determines target crash reasons corresponding to the target keywords according to preset corresponding relations, wherein the preset corresponding relations comprise corresponding relations between a plurality of preset keywords and a plurality of preset crash reasons. Illustratively, the plurality of preset crash causes include overheating of the target drive, incompatibility of the target drive with the operating system, infection of the target drive by viruses, obsolescence of the target drive, instability of power supply of the target drive, and the like. The embodiments of the present disclosure are not limited in this regard.
When the target drive log stored in the hard disk is no longer needed, the target drive log may optionally be redirected to the target physical memory reserved by the BIOS, that is, the target drive log is rewritten to the target physical memory reserved by the BIOS. The redirection process may also be performed at any time as desired. According to the embodiment of the disclosure, the target drive log is redirected to the target physical memory reserved by the BIOS, so that the storage position of the target drive log can be flexibly managed and controlled, and a precondition is provided for a subsequent acquisition scheme of the target drive log when the computing equipment is crashed and restarted.
Schematically, when the computing device completes the startup initialization process and enters a normal working state, the target drive log can be redirected to the target physical memory reserved by the BIOS through the log redirection switch, where the log redirection switch is a preset switch for indicating the target drive log to be redirected.
Optionally, when the computing device crashes and restarts, performing a power-on operation of the BIOS; the step 102 is restarted, namely, the step of reserving the target physical memory by the BIOS in response to the memory reservation indication.
A crash may generally refer to a state in which a computing device is not functioning properly, such as when the computing device is in a black screen, a processor of the computing device is unable to execute instructions of the computing device, an input device such as a mouse or keyboard of the computing device is not accepting input, and so on.
The crash may occur at any stage in the use of the computing device, illustratively, during the test target driving process, when the computing device crashes and is forced to restart, the power-on operation of the BIOS may be performed, at this time, since the power-on operation of the BIOS is performed, the process does not need to return to step 101 to perform the startup of the BIOS, and the process may return to step 102 to start to perform the execution. According to the embodiment of the disclosure, when a crash occurs and the BIOS is restarted, the power-on operation of the BIOS is executed, the execution response to the memory reservation instruction is restarted, the target physical memory is reserved through the BIOS, the target drive log is dumped to the hard disk, and the like, so that convenience in analyzing the crash problem is further improved.
Referring to fig. 2, which is a schematic diagram illustrating a method for detecting and analyzing a crash according to an exemplary embodiment of the present disclosure, in an illustrative example, as shown in fig. 2, a computing device includes: physical memory 21 available to the operating system, target physical memory 22, drive 23, and hard disk 24. When the BIOS is started, the target identifier 25 is read from the CMOS through the BIOS, and the target identifier 25 is used for indicating whether the BIOS needs to reserve physical memory or not; when the target identifier 25 indicates that the BIOS needs to reserve the physical memory, reserving, by the BIOS, the target physical memory 22, where the target physical memory 22 is used to store a drive log of the drive 23; the drive log of the drive 23 is dumped to the hard disk 24.
Referring to fig. 3, a flowchart of a method for detecting and analyzing a crash according to another exemplary embodiment of the present disclosure is shown, where the method is used in a computing device for illustration. The method comprises the following steps.
Step 301, starting the BIOS when the computer is started.
In step 302, the BIOS enters an initialization process, reads the target identifier, and reserves the target physical memory through the BIOS when the target identifier indicates that the BIOS needs to reserve the physical memory.
Optionally, the target identifier is read from the CMOS by the BIOS, and when the target identifier indicates that the BIOS needs to reserve the physical memory, the target physical memory is reserved by the BIOS, and other physical memories except the target physical memory are submitted to the kernel of the operating system. When the target identifier indicates that the BIOS does not need to reserve the physical memory, the BIOS submits all the physical memory to the kernel of the operating system.
The target physical memory is used for storing a target drive log, and the target drive log indicates the working state of a target drive before a crash.
Step 303, loading the target drive after the initialization of the operating system is completed.
Step 304, when the target driver queries that the BIOS has reserved target physical memory, the target physical memory is obtained and mapped.
When the reserved target physical memory exists in the BIOS, the reserved target physical memory in the BIOS is obtained, the target physical memory is mapped to the virtual address space, and then whether a target drive log exists in the target physical memory is detected. And when the BIOS is queried that the reserved target physical memory does not exist, continuing to initialize, and completing the starting-up flow.
Step 305, when it is detected that the target drive log exists in the target physical memory, dumping the target drive log to the hard disk.
And when the target drive log exists in the target physical memory, dumping the target drive log into the hard disk. And when the fact that the target drive log does not exist in the target physical memory is detected, initializing is continued, and the starting-up process is completed.
And 306, extracting a target drive log from the hard disk and performing detection analysis.
Step 307, when the system enters a normal working state, the target drive log is redirected to the target physical memory reserved by the BIOS.
In step 308, when the computing device crashes and restarts, the power-on operation of the BIOS is performed, and the above-mentioned step 302 is restarted.
