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.

Example 1
Fig. 1 is a flowchart of a log processing method according to an embodiment of the present invention, where the embodiment is applicable to storing a BIOS (Basic Input Output System ) log and outputting a BIOS log, and the method may be performed by a log processing device according to an embodiment of the present invention, and the device may be implemented by software and/or hardware. Referring to fig. 1, the log processing method provided in this embodiment includes:
Step 110, if the BIOS determines that the log transfer option is opened, the initial memory information of the target shared memory is read; wherein, the BMC and BIOS can access the target shared memory.
If the log transfer option is opened, the log is indicated to be processed in the target shared memory, and if the log transfer option is not opened, the log is indicated to be processed in the original preset mode, for example, output to the serial port, which is not limited in this embodiment.
For example, after the machine is powered on, the BIOS reads the setting of the BIOS at the beginning of the preparation phase of the EFI (Extensible Firmware Interface ) environment, and determines whether the log transfer option is turned on according to the variable related to the log transfer option in the setting.
If the log transfer option is judged to be opened, the initial memory information of the target shared memory is read; the target shared memory is a shared memory storing logs, and the BMC (Baseboard Management Controller ) and the BIOS can access the shared memory, for example, VGA (Video Graphics Array ), which is not limited in this embodiment.
The initial memory information of the target shared memory is the memory information when the log is not stored, and may include an initial memory address, an initial memory size, and the like of the target shared memory. The initial memory information can be obtained by reading a register related to the BMC and written with the memory information, and if the target shared memory is VGA memory, the initial memory information can be obtained by reading a register, which is contained in VGA equipment and contains the BMC chip, of the memory information.
In this embodiment, optionally, before determining, by the BIOS, whether the log-forwarding option is turned on, the method further includes:
and in response to the switching operation according to the log transfer option, determining the memory size of the usable memory of the target shared memory through the BIOS.
The log transfer option may be located in the BIOS setting interface, and the switching operation of the log transfer option may be triggered manually or actively by the system, which is not limited in this embodiment.
By way of example, if the log transfer option is detected to be open, the BIOS may set the size of the target shared memory to an extended size, such as 64M, and if the log transfer option is detected to be closed, the BIOS may set the size of the target shared memory to a default size, such as 16M or 32M.
The advantages of this arrangement are that: different memory use requirements are determined through the switching operation of the log transfer options, so that the size of the target shared memory is determined according to the different use requirements, for example, when the log is required to be stored in the target shared memory, the target shared memory is enlarged, and the problem that the log cannot be stored due to too small storage space of the target shared memory is avoided; when the log is not needed to be stored in the target shared memory, the size of the target shared memory is kept, the memory space in the target shared memory is prevented from being idle, and the memory utilization rate of the target shared memory is improved; thereby improving the effectiveness of memory size determination of the usable memory of the target shared memory.
Step 120, determining memory storage information according to the initial memory information and the first preset setting information by the BIOS, and storing a current log in the target shared memory according to the memory storage information to generate log storage information; the first preset setting information is determined through the BMC and the BIOS.
The first preset setting information is determined by the BMC and the BIOS, and may be a mode about how to store the log, which is pre-agreed between the BIOS and the BMC, for example, may include static storage and dynamic storage, where the static storage may be a storage mode, for example, the size of the target shared memory is 64M, and if the fixed 32M is used to store the log, the starting address and the ending address of the storage are determined correspondingly.
The dynamic storage can be determined according to the actual size of the log to be stored or other storage information in the target shared memory in a storage mode, namely the starting address and the ending address of the storage change according to the actual storage condition. For example, if the size of the log to be stored exceeds a preset threshold, 32M in the target shared memory is allocated for storage, and if the size of the log to be stored is smaller than or equal to the preset threshold, 16M in the target shared memory is allocated for storage, so that the problem that the storage space is insufficient due to the large amount of the log to be stored or the excessive memory space is occupied when the amount of the log to be stored is small is avoided, and the flexibility of log storage is improved. Or the log and other storage information are stored adjacently in the target shared memory, the other storage information originally stores the size of 2M, the 4M is needed to be stored, and the address for storing the log needs to be offset by 2M correspondingly.
And determining memory storage information according to the initial memory information and the first preset setting information, namely determining a storage mode according to the first preset setting information, determining memory storage information to be followed in storage according to the storage mode and the initial memory information, and actually storing according to the memory storage information. For example, if the initial memory information includes an initial memory address of the target shared memory, and the initial memory size is 64M, the first preset setting information is static information, including fixing a start address and a stop address in the target shared memory, and a space with a size of 32M is used for storing the log, the memory storage information is: the log may be stored in a space with an initial memory address, a fixed starting address and ending address in a target shared memory with a size of 64M, and a size of 32M.
The current log is stored in the target shared memory according to the memory storage information, wherein the current log is a BIOS log to be stored currently, and the BIOS log is a log generated in the BIOS stage, may be all the BIOS logs generated currently, or may be all the BIOS logs to be acquired currently, for example, may be part of BIOS logs of specific sources in all the BIOS logs, which is not limited in this embodiment.
Optionally, before the current log is stored in the target shared memory according to the memory storage information, the target shared memory may be preprocessed, so that the efficiency of subsequent log storage is improved, a preprocessing manner may be determined according to a data structure during log storage, and if the data structure during log storage is an exemplary bidirectional linked list, the preprocessing may be memory alignment processing on the target shared memory.
And generating log storage information after storing the current log, wherein the log storage information is information obtained after actually storing the log, such as data structure information, log number, storage address of a first log, storage address of a last log and the like, when storing the log, and the data structure information can be a bidirectional linked list and the like, which is not limited in the embodiment.
In this embodiment, optionally, before storing the current log in the target shared memory according to the memory storage information, the method further includes:
acquiring a current log through a BIOS (basic input output system), and judging whether an ending mark exists in the current log;
if the current log exists, determining a separation mode of the current log according to the ending mark, and determining a storage mode of the current log according to the separation mode.
The current log is obtained by the BIOS, and the current log is composed of one or more bytes.
If the ending mark exists, the ending mark exists between bytes of the current log, the ending mark can be added through a preset function when the log is generated, the adding position can be determined manually or the log generating source can be determined automatically, for example, if the obtained log source changes, the ending mark is added after the last byte obtained before the change. Where the end identifier is, for example, "/n", which is not limiting in this embodiment.
Separating the current logs according to an ending identifier, wherein the ending identifier is used for identifying that a single log in the current log ends, bytes before the ending identifier can be stored as a single log, and if the current log comprises byte 1, byte 2..byte 12, line feed identifier, byte 13 and byte 14..byte 20, then bytes 1-12 and bytes 13-20 can be separated, and bytes 1-12 and bytes 13-20 can be respectively stored as a single log in a target shared memory.
The advantages of this arrangement are that: if a single byte is stored as a single log, the header file of the log needs to be generated when each log is stored, and the header file occupies part of the memory, so that when the number of bytes is too large, the log storage occupies the memory space of too many target shared memories; if all bytes are stored as a single log, the log information amount is large, and the subsequent log analysis speed is affected. According to whether the end mark exists in the current log, the current log is separated and stored, and the analysis speed of the log in the subsequent log reading process is improved under the condition that the log storage does not occupy excessive space.
130, determining a reading execution object of the log according to the mode type of the current management mode, and reading the target log to a preset output position from the target shared memory according to the reading execution object, the memory storage information and the log storage information; the current management mode comprises at least one of an out-of-band management mode and an in-band management mode.
And determining a reading execution object of the log according to the mode type of the current management mode, wherein the reading execution object is an object for executing the reading of the log from the shared memory. Different current management modes, for example, if the current management mode is an out-of-band management mode, that is, when the machine main system is managed by the BMC, the read execution object may be determined to be the BMC; if the current management mode is an in-band management mode, that is, when the machine main system is managed by the CPU, the read execution object may be determined as an operating system, a third-party hardware tool, or the like, and if the current management mode is an in-band management mode, the determined read execution object may be any object capable of executing a log read operation, or may be determined according to the current system running condition, for example, when the system is down and cannot enter the operating system, the log read operation may be executed by other currently available read execution objects.
And reading the target log from the target shared memory to a preset output position according to the reading execution object, the memory storage information and the log storage information, wherein the target log is the log which needs to be output currently, can be all logs stored in the target shared memory or partial logs, and is not limited in the embodiment. The reading mode can be that the position of the log in the shared memory is determined according to the memory storage information by reading the execution object, and the required log is analyzed from the shared memory by the log storage information so as to read. And outputting the read log to a preset output position, wherein the output mode can be that the log is directly output to the preset output position, and the preset output position can be any preset position for storing the output log.
Optionally, the range of the stored output log can be determined according to the size of the storage space of the preset output position, and if the storage space is larger than the corresponding preset range threshold, the log generated by multiple times of machine startup can be stored, so that analysis, comparison and tracking of the log can be performed at a later stage; if the storage space is smaller than the corresponding preset range threshold value, the log generated by single starting of the machine can be saved, and the old log originally stored is covered when the new starting log is generated, so that the space is saved.
According to the technical scheme provided by the embodiment, under the condition that the Debug mode is started, the current logs are stored in the target shared memory which can be accessed by both the BMC and the BIOS, so that the BMC and the BIOS can process the logs conveniently, and the application range of log processing is improved; and the current log is stored in the target shared memory, and can be acquired from the target shared memory when the log is needed, so that the current log is not required to be output to the serial port in real time in the starting process of the machine, the problem that the starting time of the machine is prolonged due to real-time output is avoided, and the log can be stored under the condition of less influence on the starting speed.
According to the determined memory storage information, the current log is stored in the shared memory, so that the current log is stored in the target shared memory according to the rule, the validity of log storage is improved, log reading can be carried out according to the memory storage information and the generated log storage information, unordered query is not needed in the target shared memory, and the pertinence and the efficiency of log acquisition are improved. And different reading execution objects are determined according to different management modes, so that logs can be obtained from the target shared memory in different current management modes, and the applicability of log obtaining is improved.
