Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a flowchart illustrating an implementation of a dump processing method for an operating system kernel, which is applicable to an electronic device, such as a computer or a server, loaded with an operating system and capable of performing data processing. The technical scheme in the embodiment is mainly used for improving the dump reliability.
Specifically, the method in this embodiment may include the following steps:
step 101: and under the condition that the kernel of the operating system is started, initializing the nonvolatile equipment connected with the electronic equipment where the kernel of the operating system is located.
The starting of the operating system kernel may be understood as that the operating system kernel starts to be started or is in the process of starting after the electronic device is started, at this time, the initialization processing is performed on the nonvolatile device connected to the electronic device where the operating system kernel is located, so that the initialized nonvolatile device can be used as a data storage device to realize a dump function.
Step 102: and monitoring whether the kernel of the operating system is down, and executing the step 103 under the condition that the kernel of the operating system is down.
The downtime of the kernel of the operating system may be the downtime caused by the occurrence of the internal error kemel panic of the kernel of the operating system, or the downtime caused by other conditions, that is, the dump scheme in this embodiment may be applicable to the kernel downtime scenario caused by any condition, so as to implement dump.
Step 103: kernel dump data is obtained.
In this embodiment, kernel dump data that can be used for post analysis can be obtained in the operating system kernel and the hard disk in the electronic device.
Step 104: and transmitting the kernel dump data to the nonvolatile device so as to store the kernel dump data in the nonvolatile device.
That is to say, in this embodiment, the nonvolatile device connected to the electronic device is used as a kernel dump device to store kernel dump data, so as to analyze the downtime event in the following process.
In a specific implementation, the nonvolatile device may be a nonvolatile memory device connected to the electronic device, and thus, data reading and writing of the nonvolatile memory device is the same as that of a memory, and an access process of kernel dump data in the nonvolatile memory device may be implemented as a simple memory copy without depending on any other kernel functions. Therefore, the access conciseness of the nonvolatile memory device in the dump enables the dump to be carried out in the original kernel, namely the kernel of the operating system, without worrying about the influence of the instability of the original kernel, without the participation of an additional dump kernel, and the problem of loading failure of the dump kernel when the crash occurs is also avoided.
According to the above scheme, in the dump processing method for the operating system kernel provided in the embodiment of the present application, the nonvolatile device connected to the electronic device where the operating system kernel is located is initialized when the operating system kernel is started, and then the kernel dump data can be obtained and transmitted to the nonvolatile device when the operating system kernel is down, so that the kernel dump data is stored in the nonvolatile device. Therefore, the dump process realized by the method is relatively simple, the participation of a dump kernel is not needed, whether the kernel of the operating system is stable or not is not needed to be considered, and even if the system hardware cannot work normally, the kernel dump data can be safely stored in the initialized nonvolatile equipment, so that the dump failure condition is avoided, and the dump reliability is improved.
In one implementation, the non-volatile device, which is connected to the electronic device and has undergone the initialization process, includes at least one storage space, and the storage space is configured in a dump mode, so that the storage space configured in the dump mode can store kernel dump data obtained when a kernel of the operating system is down, and thus, the dump is implemented by the storage space configured in the dump mode in the non-volatile device.
It should be noted that the nonvolatile device may further include other storage spaces, which can be used for storing other data. As shown in fig. 2, an address space capable of storing data in a nonvolatile device is divided into a plurality of memory spaces, wherein a memory space a configured in a dump mode is used to implement a dump, i.e., to store kernel dump data, and the other memory space b is used to store other data.
The memory space configured in the nonvolatile device in the dump mode may be a space divided by default in the nonvolatile device, that is, in an initial state, the space in the nonvolatile device that may default a preset address to the memory space in the dump mode, or the memory space configured in the dump mode in the nonvolatile device may also be set according to an operation of a user, and the following is implemented:
in a specific implementation, in this embodiment, a configuration operation is performed on a nonvolatile device serving as a dump device in advance, for example, after the nonvolatile device is connected to an electronic device, a user may perform a dump configuration operation in a configuration interface corresponding to the nonvolatile device, as shown in fig. 3, at least a configuration control capable of configuring a storage space in the nonvolatile device in a dump mode is provided in the configuration interface, based on which, in this embodiment, a dump configuration operation for the configuration interface corresponding to the nonvolatile device may be accepted, so that the storage space in the nonvolatile device corresponding to the dump configuration operation is set to be in the dump mode according to the dump configuration operation. For example, a user operates a configuration control in the configuration interface to set the address space a to be in a dump mode, and at this time, the address space a, i.e., a storage space as a dump mode, can be used for storing kernel dump data.
It should be noted that the above dump configuration operation for the storage space may be performed when the kernel of the operating system is started or after the kernel of the operating system is started, so as to complete setting of the storage space in the dump mode in the nonvolatile device, so that the acquired kernel dump data can be safely and reliably transmitted to the storage space in the dump mode in the nonvolatile device when the kernel of the operating system is down, and dump is implemented.
Further, the above dump configuration operation includes at least a mode configuration operation and a space configuration operation, where the mode configuration operation is used to set the storage space in the nonvolatile device to be in the dump mode, that is, determine to set the address space in the nonvolatile device to be the storage space in the dump mode, and the space configuration operation is used to set the space size and/or the space address of the storage space in the nonvolatile device to be in the dump mode, that is, after determining to set the address space in the nonvolatile device to be the storage space in the dump mode, determine which address spaces are the storage spaces in the dump mode, for example, specify the address space a, that is, the address space including addresses a1 to an, as the storage space in the dump mode, and n is a positive integer greater than or equal to 1.
In a specific implementation, the mode configuration operation performed by the user on the configuration interface in this embodiment may also be used to set the storage space in the nonvolatile device to be in another mode, such as a blcok mode, for example, as shown in fig. 4, the configuration interface includes a plurality of mode configuration controls, each mode configuration control corresponds to a type or a mode of the address space, such as a dump mode or a block mode, and the user may select a corresponding mode configuration control in the configuration interface to set the address space of the nonvolatile device to be in the mode corresponding to the control, for example, in this embodiment, the user may generate a corresponding mode configuration operation by clicking the mode configuration control corresponding to the dump mode in the configuration interface, so as to set the address space in the nonvolatile device to be in the dump mode; and corresponding to the space configuration control under the corresponding mode configuration control, the user may perform configuration operation on the space size of the address space under the corresponding mode or the space address, such as the start address, through the space configuration control, for example, in this embodiment, the user selects "30%" in the space configuration control corresponding to the mode configuration control under the dump mode, and then the space configuration operation may be generated, so as to conveniently set 30% of the address space of the nonvolatile device as the storage space in the dump mode, thereby implementing dump parameter configuration of the nonvolatile device.
In one implementation manner, before performing initialization processing on a nonvolatile device connected to an electronic device where an operating system kernel is located in step 101, the method in this embodiment may further include the following steps, as shown in fig. 5:
step 105: and identifying whether preset target parameters exist in the kernel of the operating system, and if so, executing step 106.
The target parameters characterize that the electronic device uses a nonvolatile device to perform kernel dump. Based on this, if the target parameter exists in the kernel of the operating system, the electronic device determines to use the connected nonvolatile device to perform kernel dump if the kernel of the operating system is down, and if the target parameter does not exist in the operating system, the electronic device does not use the nonvolatile device to perform kernel dump if the kernel of the operating system is down.
Step 106: and searching the connected nonvolatile equipment in an equipment list of the electronic equipment, and if the nonvolatile equipment is searched, executing the step 101 so as to initialize the nonvolatile equipment connected with the electronic equipment where the kernel of the operating system is located, so that the initialized nonvolatile equipment has the function of realizing dump, and further realizing kernel dump when the kernel of the operating system is down.
In this embodiment, it may be found whether a nonvolatile device is connected in a device list formed by identifiers of all devices connected after the electronic device is started, if so, step 101 is executed to initialize the nonvolatile device, and if not, it is indicated that the electronic device is not connected to the nonvolatile device capable of performing kernel dump, at this time, a prompt message may be output on the electronic device or on other devices connected to the electronic device, such as a user mobile phone, to prompt a user that the nonvolatile device capable of performing kernel dump is not found, and the user is prompted to load the nonvolatile device for the electronic device.
Based on the above implementation, in step 101 in this embodiment, when performing initialization processing on a nonvolatile device connected to an electronic device where an operating system kernel is located, the implementation may be specifically implemented in the following manner, as shown in fig. 6:
step 601: a storage space in a non-volatile device configured in a dump mode is obtained.
In this embodiment, the storage space configured as the dump mode is configured on the nonvolatile device in advance, and therefore, the storage space already configured as the dump mode, such as the storage space composed of the addresses a1 to an, may be obtained through the configuration parameters on the nonvolatile device in this embodiment.
Specifically, at step 601, at least one storage space divided into the nonvolatile device, such as the storage space composed of the addresses a1 to an and the storage space composed of the addresses b1 to bn, etc., may be first obtained, and then the storage space configured in the dump mode may be found in the at least one storage space according to the configuration parameters or in other manners.
Step 602: mapping the memory space configured in the dump mode to a space of the kernel of the operating system to enable the memory space configured in the dump mode to store kernel dump data.
Specifically, in this embodiment, the operating system kernel may map the storage space configured in the dump mode to the operating system kernel, and further, in the case that the operating system kernel is down, the operating system kernel does not depend on an additional dump kernel, and even if the operating system kernel is unstable, the kernel dump data may be safely and reliably stored in the storage space configured in the dump mode due to the simplicity of the data access by the nonvolatile device, so as to implement reliable dump.
In one implementation manner, in this embodiment, a driver of a nonvolatile device that is connected to the electronic device and is to be used as a dump device is modified in advance, so that the modified driver can support the nonvolatile device to implement the dump function. Specifically, the memory space configured in the dump mode in the nonvolatile device after the driver is modified can be mapped to the space of the operating system kernel through the driver, so that the memory space configured in the dump mode in the nonvolatile device can store kernel dump data when the operating system kernel is down, and reliable dump is realized.
Referring to fig. 7, a schematic structural diagram of a dump processing apparatus of an operating system kernel according to a second embodiment of the present application is provided, where the dump processing apparatus may be applied to an electronic device, such as a computer or a server, which is loaded with an operating system and capable of performing data processing. The technical scheme in the embodiment is mainly used for improving the dump reliability.
Specifically, the apparatus in this embodiment may include the following units:
an apparatus initialization unit 701, configured to perform initialization processing on a nonvolatile apparatus connected to an electronic apparatus where the operating system kernel is located when the operating system kernel is started;
a data obtaining unit 702, configured to obtain kernel dump data when a kernel of the operating system is down;
a data transmission unit 703, configured to transmit the kernel dump data to the nonvolatile device, so that the kernel dump data is stored in the nonvolatile device.
According to the above scheme, in the dump processing apparatus for an operating system kernel provided in the second embodiment of the present application, the nonvolatile device connected to the electronic device where the operating system kernel is located is initialized when the operating system kernel is started, and then the kernel dump data can be obtained and transmitted to the nonvolatile device when the operating system kernel is down, so that the kernel dump data is stored in the nonvolatile device. Therefore, the dump process realized by the method is relatively simple, the participation of a dump kernel is not needed, whether the kernel of the operating system is stable or not is not needed to be considered, and even if the system hardware cannot work normally, the kernel dump data can be safely stored in the initialized nonvolatile equipment, so that the dump failure condition is avoided, and the dump reliability is improved.
In one implementation, the nonvolatile device includes at least one storage space, and the storage space is configured in a dump mode, so that the storage space configured in the dump mode can store the kernel dump data.
Based on this, the apparatus in the present embodiment may further include the following units, as shown in fig. 8:
an operation receiving unit 704, configured to receive a dump configuration operation for a configuration interface corresponding to the nonvolatile device, where the dump configuration operation is used to set a storage space corresponding to the dump configuration operation in the nonvolatile device to be in the dump mode.
Specifically, the dump configuration operation at least comprises a mode configuration operation and a space configuration operation;
wherein the mode configuration operation is used for setting the storage space in the nonvolatile device to be in the dump mode, and the space configuration operation is used for setting the space size and/or the space address of the storage space in the nonvolatile device to be in the dump mode.
In one implementation, the apparatus in this embodiment may further include the following units, as shown in fig. 8:
a device determining unit 705, configured to identify whether a preset target parameter exists in the operating system kernel before the device initializing unit 701 initializes the nonvolatile device connected to the electronic device where the operating system kernel is located, where the target parameter represents that the electronic device uses the nonvolatile device to perform kernel dump; searching the connected nonvolatile device in the device list of the electronic device, and triggering a device initialization unit 701 to initialize the nonvolatile device connected to the electronic device where the operating system kernel is located, if the nonvolatile device is found.
In an implementation manner, the device initialization unit 701 is specifically configured to: obtaining a storage space configured as a dump mode in the nonvolatile device, for example, first obtaining at least one storage space divided in the nonvolatile device, and then finding the storage space configured as the dump mode in the at least one storage space; then, mapping the memory space configured as the dump mode to the space of the kernel of the operating system so that the memory space configured as the dump mode can store the kernel dump data.
Referring to fig. 9, a schematic structural diagram of an electronic device according to a third embodiment of the present disclosure is provided, where the electronic device may be an electronic device connected with a nonvolatile device, such as an electronic device loaded with an operating system and capable of performing data processing, such as a computer or a server. And the non-volatile device may be a non-volatile memory device or the like. The technical scheme in the embodiment is mainly used for improving the dump reliability.
Specifically, the electronic device in this embodiment may include the following structure:
a memory 901 for storing an application program and data generated by the application program running;
a processor 902 for executing the application to implement: under the condition that the operating system kernel is started, initializing nonvolatile equipment connected with electronic equipment where the operating system kernel is located; acquiring kernel dump data under the condition that the kernel of the operating system is down; and transmitting the kernel dump data to the nonvolatile device so as to store the kernel dump data in the nonvolatile device.
Specifically, the nonvolatile device includes at least one storage space, and the storage space is configured in a dump mode, so that the storage space configured in the dump mode can store kernel dump data transmitted by the processor.
According to the above scheme, in the electronic device provided in the third embodiment of the present application, the nonvolatile device connected to the electronic device where the operating system kernel is located is initialized when the operating system kernel is started, and then the kernel dump data can be obtained and transmitted to the nonvolatile device when the operating system kernel is down, so that the kernel dump data is stored in the nonvolatile device. Therefore, the dump process realized by the method is relatively simple, the participation of a dump kernel is not needed, whether the kernel of the operating system is stable or not is not needed to be considered, and even if the system hardware cannot work normally, the kernel dump data can be safely stored in the initialized nonvolatile equipment, so that the dump failure condition is avoided, and the dump reliability is improved.
Taking a computer as an example, the technical scheme of the application is illustrated as follows:
first, in the present application, a kernel dump is implemented based on a nonvolatile memory, specifically: by utilizing the non-volatility of the nonvolatile memory and the simplicity of the access mode, the nonvolatile memory is used as kernel dump equipment, and dump data are stored when the kernel of the operating system goes down.
Based on the above implementation scheme, the method has the following advantages:
firstly, the reliability is high: in the technical scheme of the application, because the reading and writing of the nonvolatile memory are the same as those of the common memory, the main process of realizing dump can be realized as simple memory copy without depending on any other kernel functions. Due to the simplicity, the dump processing of the nonvolatile memory can be performed in the original kernel without worrying about the influence of the instability of the original kernel. Meanwhile, the problem of loading failure of the down dump kernel is also avoided.
Secondly, the applicable scene is wide: according to the technical scheme, the downtime generated in the kernel starting process can be dumped. The simplicity of the non-volatile memory access enables it to be initialized and operate normally during the early stages of kernel boot.
In addition, no extra memory is occupied: according to the technical scheme, no dump kernel is used, and extra memory is not occupied.
Finally, the configuration is simple: according to the technical scheme, the dump kernel and the related configuration thereof do not need to be generated.
In the specific implementation, in order to facilitate data management, the nonvolatile memory is divided into a plurality of spaces namespaces; and according to different use modes, namespace is correspondingly formatted. Therefore, the dump device realized by the nonvolatile memory corresponds to namespace. In order to support the kernel dumping function, a new mode for the dumping function, namely the dumping mode in the foregoing, is introduced into the nonvolatile memory. Thus, the dump device implemented by the nonvolatile memory is a namespace in dump mode.
The kernel dump function based on the nonvolatile memory mainly comprises four parts:
1. the kernel starts the initialization of the nonvolatile dump device in an early stage;
2. modifying the dump part in the kernel error processing process, thereby increasing the functions of transmitting and storing data to the nonvolatile memory;
3. modifying the drive of the nonvolatile memory device, thereby increasing the initialization and the function of namespace in a dump mode;
4. the modification of the non-volatile memory configuration tool adds the function of creating dump mode namespace in the configuration tool, namely a configuration interface.
As shown in fig. 10, a flowchart of an initialization and dump process of a dump device implemented for a nonvolatile memory, where:
when the kernel of the operating system is started, firstly detecting whether kernel starting parameters, namely target parameters in the previous text, exist to determine whether nonvolatile equipment is used as dump equipment, if so, traversing a device list in the current electronic device to find the nonvolatile equipment used as the dump equipment, and if not, continuing to start the kernel of the operating system;
after traversing a nonvolatile device serving as a dump device, acquiring a storage space "xxx" configured as a dump mode in the nonvolatile device, if the storage space "xxx" configured as the dump mode is found, initializing the storage space and mapping the storage space to an operating system kernel space, and after the operating system kernel is started, if a downtime phenomenon caused by an internal error or the like occurs, storing kernel dump data into the storage space "xxx" to implement dump.
If the electronic device is not connected to the nonvolatile device as the dump device or the nonvolatile device does not have a storage space configured as the dump mode, the kernel boot process of the operating system is continued, and at this time, the dump may be implemented by using the original dump scheme.
