All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1 is a flowchart of a BMC control method according to an embodiment of the present invention, where the method may be implemented by a BMC control device, and the BMC control device may be implemented in hardware and/or software, and the BMC control device may be configured in a dump data tool kdump when a kernel error occurs in the BMC. As shown in fig. 1, the method includes:
Step 110, when it is detected that the target BMC has a kernel error, storing at least one restart reason currently corresponding to the target BMC and class information corresponding to each restart reason into a preset cache space.
In this embodiment, kdump may be a tool for dumping memory running data when a target BMC experiences a system crash and a deadlock. When the kdump detects that the target BMC has kenrel panic (i.e. kernel error), the restart reason currently corresponding to the target BMC and class information corresponding to each restart reason can be stored into a preset cache space.
In a specific embodiment, optionally, the restart cause may be a system event that causes an error in the target BMC kernel, for example, a reset key corresponding to the target BMC is triggered, the target BMC is powered off, and a flash memory chip corresponding to the target BMC is switched. The class information may be a specific event type corresponding to the restart reason. The preset buffer space may be a dedicated storage space with smaller capacity, which is used for storing the restart reason and the class information.
In this step, optionally, when the core error is detected in the target BMC, the restart reason and the class information corresponding to the restart reason may be obtained according to the event currently executed by the target BMC.
And step 120, after detecting that the target BMC starts restarting, acquiring target operation data from a target memory corresponding to the target BMC according to each restarting reason stored in the cache space and class information corresponding to each restarting reason.
In this embodiment, the target operation data is operation data corresponding to when the target BMC generates a kernel error. And after the kdump detects that the target BMC starts restarting, each restarting reason and class information corresponding to each restarting reason can be obtained from the cache space.
In a specific embodiment, after obtaining each restart reason and class information corresponding to each restart reason, each restart reason and corresponding class information may be used as a query condition, and then in a memory (i.e. a target memory) of the target BMC, operation data matched with each query condition is obtained as target operation data.
Alternatively, the target Memory may be a Synchronous Dynamic Random Access Memory (SDRAM).
And 130, the target operation data is transferred to a nonvolatile memory, so that an error reason corresponding to the target BMC is determined according to the target operation data.
In this embodiment, kdump may transfer the target operation data from the target memory to a preset nonvolatile memory, so that a developer determines, according to the target operation data in the nonvolatile memory, an error cause corresponding to the target BMC.
In a specific embodiment, optionally, the error cause may be a system code cause that causes the target BMC to generate a kernel error. After determining the cause of the error, the developer may improve the system service logic code of the target BMC.
In this step, optionally, the non-volatile memory may be an embedded multimedia card (Embedded Multi Media Card, EMMC).
And 140, controlling the kernel of the target BMC to start, and controlling a boot loader (Universal Boot Loader, uboot) in the target BMC to finish initialization.
In this embodiment, the target running data is transferred to the nonvolatile memory before the target BMC kernel is started and before the uboot program is initialized, so that the target running data in the target memory can be prevented from being covered by the new running data, the crash field of the target BMC kernel can be saved, and convenience is brought to debugging codes of research personnel.
In a specific embodiment, after detecting that the target running data is transferred, the restart reason and the class information in the cache space may be deleted, so that the cache space stores the restart reason and the class information corresponding to the next kernel error.
In a specific embodiment, when the core error of the target BMC is detected, the current time may also be stored in the cache space, so as to obtain the target running data from the target memory according to each restart reason stored in the cache space, class information corresponding to each restart reason, and the current time.
In this embodiment, since the storage space occupied by the restart cause and the class information is smaller, the occupation of the target BMC storage resource can be reduced by presetting the cache space for storing the restart cause and the class information, and the operability and practicality of the BMC control method are improved; secondly, in the embodiment, the target operation data can be obtained through restarting the reason and the class information, and the capture kernel in the kexec mechanism is not required to be used for obtaining the operation data, so that the process of installing kdump into the BMC embedded environment can be omitted, and the development difficulty of a BMC control method can be reduced.
According to the technical scheme provided by the embodiment of the invention, when the kernel error of the target BMC is detected, at least one restarting reason corresponding to the target BMC currently and class information corresponding to each restarting reason are stored into the cache space; after the target BMC is detected to start restarting, acquiring target operation data from a target memory corresponding to the target BMC according to each restarting reason stored in a cache space and class information corresponding to each restarting reason; the target operation data is transferred to a nonvolatile memory, so that an error reason corresponding to the target BMC is determined according to the target operation data; the technical means of controlling the kernel of the target BMC to start and controlling the uboot program in the target BMC to finish initialization can reduce the occupation of storage resources of the target BMC and reduce the development difficulty of a BMC control method.
Fig. 2 is a flowchart of another BMC control method according to an embodiment of the present invention, as shown in fig. 2, where the method includes:
step 210, when it is detected that the target BMC has a kernel error, storing at least one restart reason currently corresponding to the target BMC and class information corresponding to each restart reason into a preset cache space.
Step 220, after detecting that the target BMC starts restarting, determining whether a target restart reason exists in the cache space according to each restart reason stored in the cache space and class information corresponding to each restart reason.
In this embodiment, the target restart reason may be a preset important system event that triggers a target BMC kernel error. Specifically, before detecting that the target BMC has a kernel error, the restart reason with the highest importance level may be used as the target restart reason according to a plurality of restart reasons corresponding to the target BMC in the history operation process and the importance levels corresponding to the restart reasons. The importance level may be understood as the severity of the error corresponding to the restart cause. Specifically, the target restart cause may be that the target BMC generates a fatal error (sys_panic).
Step 230, if there is a target restart reason in the cache space, judging whether the class information corresponding to the target restart reason is the target class information.
In this embodiment, the target class information may be a preset important event type that triggers the target BMC kernel error. Specifically, the target class information may be a watchdog RESET (sys_wdt_reset).
In this step, if there is a target restart reason in the cache space, it is determined whether the class information corresponding to the target restart reason in the cache space is target class information.
Step 240, if the class information corresponding to the target restart reason is the target class information, acquiring target operation data matched with the target restart reason and the target class information from a target memory.
In this embodiment, if the target restart reason and the target class information exist in the cache space, the target restart reason and the target class information may be used as a query condition, and in the target memory, the operation data matched with the query condition may be obtained as target operation data.
In a specific embodiment, if the target restart reason or the target class information does not exist in the cache space, the method may execute the operation of controlling the kernel of the target BMC to start in step 260, and controlling the uboot program in the target BMC to complete the initialization operation.
The method has the advantages that the kernel errors of the target BMC can be processed in time by acquiring the operation data under the condition of higher error severity and transferring the operation data, so that the stability of the target BMC in the subsequent operation process is improved; second, for lower error severity cases, these errors have less impact on the running process of the target BMC and therefore may be disregarded.
Step 250, the target operation data is transferred to a nonvolatile memory.
Step 260, controlling the kernel of the target BMC to start, and controlling the uboot program in the target BMC to complete initialization.
Step 270, copying the target operation data in the nonvolatile memory into a preset virtual machine; and the kernel debugging tool is pre-installed in the virtual machine.
In this embodiment, the kernel debug tool may be a tool for analyzing target operational data. Specifically, the kernel debug tool may be Crash.
And 280, analyzing the target operation data according to an original kernel operation file corresponding to the target BMC by using a kernel debugging tool through the virtual machine, and obtaining an error reason corresponding to the target BMC.
In this embodiment, the original kernel running file may be a vmlinux file. Specifically, the virtual machine may analyze the target operation data according to the vmlinux file corresponding to the target BMC by using Crash, and obtain an error cause corresponding to the target BMC according to an analysis result.
The advantage of this arrangement is that automation of the error cause determination process can be achieved, improving efficiency of the target BMC; secondly, since the program debugging tool (GNU Symbolic Debugger, GDB) is embedded in Crash, the accuracy of the error cause determination result can be improved by analyzing the target operation data by using Crash.
According to the technical scheme provided by the embodiment of the invention, when the kernel error of the target BMC is detected, at least one restarting reason currently corresponding to the target BMC and class information corresponding to each restarting reason are stored in the preset cache space, after the restarting of the target BMC is detected, whether the target restarting reason exists in the cache space is judged, if the target restarting reason exists in the cache space, whether the class information corresponding to the target restarting reason is the target class information is judged, if yes, target running data matched with the target restarting reason and the target class information is acquired from a target memory, the target running data is transferred into a nonvolatile memory, the kernel of the target BMC is controlled to be started, a uboot program in the target BMC is controlled to complete initialization, the target running data in the nonvolatile memory is copied into a virtual machine, and the target running data is analyzed by using a kernel debugging tool through the virtual machine according to an original kernel running file of the target BMC, so that the occupation of storage resources of the target BMC can be reduced, and the difficulty of developing a control method can be reduced.
Fig. 3 is a flowchart of another BMC control method according to an embodiment of the present invention, as shown in fig. 3, where the method includes:
Step 310, setting a cache space according to a preset capacity in a standby memory corresponding to the target BMC.
In this step, the cache space may be set according to a preset capacity in the reserved memory (i.e., the spare memory) corresponding to the target BMC. Alternatively, the capacity may be 1M, and specific values may be preset according to practical situations, which is not limited in this embodiment.
The setting has the advantages that the occupation of storage resources of the target BMC can be reduced by setting the cache space with smaller capacity, and the operability and practicability of the BMC control method are improved.
Step 320, when detecting that the target BMC has a kernel error, determining a memory address corresponding to the standby memory according to a configuration file corresponding to the target BMC.
In a specific embodiment, the memory address corresponding to the spare memory is pre-recorded in the configuration file.
Step 330, locating the standby memory according to the memory address, and storing at least one restart reason currently corresponding to the target BMC and class information corresponding to each restart reason in a cache space in the standby memory.
The configuration file control method has the advantages that the memory address can be quickly obtained according to the configuration file corresponding to the target BMC, and the restarting reason and the class information are written into the cache space, so that the control efficiency of the BMC can be improved.
And step 340, after detecting that the target BMC starts restarting, acquiring target operation data from a target memory corresponding to the target BMC according to each restarting reason stored in the cache space and class information corresponding to each restarting reason.
And 350, generating a target abnormal log matched with the target operation data according to a preset log file format.
In this embodiment, optionally, standard fields corresponding to different data types are preset in the log file format. After the target operation data is obtained, the target operation data can be converted according to standard fields in a log file format to obtain a target exception log.
The advantage of this arrangement is that by generating the target abnormality log that matches the target operation data, the subsequent analysis of the target abnormality log is facilitated, whereby the accuracy of the error cause determination result can be ensured.
And step 360, the target exception log is transferred to a nonvolatile memory, so that an error reason corresponding to the target BMC is determined according to the target exception log.
In one implementation of this embodiment, before the target exception log is transferred to the nonvolatile memory, the method further includes: counting the number of historical abnormal logs in the nonvolatile memory, and judging whether the number is larger than a preset threshold value or not; if yes, determining a target historical abnormal log to be reserved according to the storage time corresponding to each historical abnormal log and the preset threshold; and deleting the residual historical exception logs except the target historical exception log in the nonvolatile memory.
In this embodiment, the history exception log is an exception log generated by the target BMC during the history running process. In order to avoid the problem of failure in the transfer of the target exception log caused by insufficient space of the nonvolatile memory, the embodiment provides an implementation manner of dynamically deleting the historical exception log before the target exception log is transferred.
In a specific embodiment, if the number of the history exception logs in the nonvolatile memory is greater than a preset threshold, the history exception log with the storage time closest to the current time may be reserved as the target history exception log according to the storage time corresponding to each history exception log, and the remaining history exception logs except the target history exception log may be deleted. The number of the target historical abnormal logs is equal to the preset threshold value.
The method has the advantages that the problem of failure in the transfer of the target abnormal log caused by insufficient space of the nonvolatile memory can be avoided, so that the crashed site of the target BMC kernel can be smoothly saved, and convenience is brought to the subsequent error cause determination process.
