Description

Technical Field

[0001] This invention relates to the field of server technology, and in particular to a basic input / output system firmware upgrade method and electronic device. Background Technology

[0002] With the accelerating pace of server demand iterations, the update frequency of BIOS (Basic Input / Output System) has also increased significantly. In practical applications, users typically customize the BIOS according to their own business needs. During BIOS firmware upgrades, users generally expect their customized configurations to be retained. Relying on manual backup and recovery of configurations is not only cumbersome but also prone to errors due to human negligence, resulting in overall low efficiency. Although some related technologies now have configuration export and import functions, they still have significant shortcomings in handling the semantic evolution and changes in the scope of application of configuration items. When existing configuration items are deleted, renamed, or their parameter ranges are adjusted in new firmware versions, directly using related technologies for configuration migration often leads to compatibility issues, and in severe cases, may even cause the system to fail to boot, affecting business continuity.

[0003] Therefore, in view of the shortcomings of existing technical solutions, the present invention provides a basic input / output system firmware upgrade method. Summary of the Invention

[0019] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] The embodiments of this application provide a firmware upgrade method for a basic input / output system. The method is described in detail below in conjunction with the execution flow of the basic input / output system firmware upgrade method.

[0021] S101: Obtain the current configuration data of the basic input / output system firmware, perform a structured transformation on the current configuration data, and obtain the first configuration file.

[0022] Here, the basic input / output system firmware is a set of core programs embedded in the motherboard memory chip in the computer system, responsible for key functions such as hardware initialization, system self-test, and operating system boot.

[0023] The configuration data may include system time, date, motherboard information, language settings, CPU (Central Processing Unit) configuration, memory settings, chipset and I / O (Input / Output) settings, control system boot order settings, control system boot method settings, security settings, power management, voltage and overclocking settings, and integrated peripheral settings. Specifically, CPU configuration may include enabling / disabling CPU dynamic frequency adjustment for power saving, adjusting the CPU multiplier, setting the CPU core voltage, enabling CPU sleep mode, and enabling virtualization support.

[0024] Here, structured transformation is used to convert the current configuration data into a file with the same format as the second configuration file so that both can be processed.

[0025] Structured conversion can be performed using tools, UEFI NVRAM parsing, or scripts.

[0026] For example, formatting conversion can be used to convert binary configurations into structured JSON / XML format.

[0027] S102: Obtain the upgrade configuration data of the basic input / output system standard upgrade firmware to obtain the second configuration file.

[0028] Here, the basic input / output system standard upgrade firmware is the upgrade firmware without configuration migration.

[0029] S103: Compare the configuration parameters of the first configuration file and the configuration parameters of the second configuration file to determine the differences in configuration items.

[0030] Specifically, the differences in configuration items can be determined by comparing the configuration parameters of each configuration item in the first configuration file with the corresponding configuration item in the second configuration file.

[0031] S104: Process the difference configuration items according to the difference processing rules to obtain the target configuration file, and perform basic input / output system firmware upgrade according to the target configuration file.

[0032] Here, the difference handling rules can be different for different difference configuration items.

[0033] The target configuration file includes the configuration of the basic input / output system standard upgrade firmware and the processed difference configuration items. The processed difference configuration items can be obtained from the current configuration data through methods such as retention and mapping.

[0034] Specifically, the target upgrade firmware is obtained based on the target configuration file and firmware template, and the BIOS is upgraded using the target upgrade firmware.

[0035] It should be noted that this application retains user configuration as much as possible, avoids upgrade or startup failures due to configuration conflicts, efficiently completes firmware upgrades, and improves accuracy and automation.

[0036] In some specific implementations, the current configuration data of the basic input / output system firmware is obtained, and the current configuration data is structured to obtain a first configuration file, including:

[0037] Parse the basic input / output system firmware and locate the configuration data area of ​​the basic input / output system firmware based on the configuration area identifier;

[0038] The configuration data in the configuration data area is structured and transformed using a conversion tool to obtain the first configuration file.

[0039] The configuration region identifier can be a Setup Module GUID.

[0040] The conversion tool can be IFR (Internal Forms Representation) to XML.

[0041] Specifically, the configuration block is located by parsing the Setup Module GUID in the header of the current firmware BIOS module, and a structured configuration file is generated using the IFR to XML conversion tool.

[0042] In this way, the originally closed, binary configuration logic can be transformed into readable, analyzable, and programmable structured data.

[0043] In some specific implementations, based on the configuration parameters, the configuration parameters of the first configuration file and the configuration parameters of the second configuration file are compared to determine the differing configuration items, including:

[0044] Identify user configuration items based on preset identifiers in the first configuration file;

[0045] Compare the configuration parameters of the user configuration items in the first configuration file with the configuration parameters of the corresponding user configuration items in the second configuration file to determine the differences in configuration items.

[0046] The default flag can be Non-Default.

[0047] Specifically, when a user modifies the configuration, the modified configuration item is marked as Non-Default in real time. During BIOS firmware upgrades, the different configuration items are identified directly through the Non-Default identifier.

[0048] Specifically, after determining that a configuration item is a differential configuration item, the configuration parameters of the differential configuration item can be compared according to the configuration item name, data type, value range and configuration value to determine the type of the differential configuration item, and then processed according to the differential processing rules.

[0049] In this way, different configuration items can be quickly identified through preset identifiers.

[0050] In some specific implementations, comparing the configuration parameters of the first configuration file and the configuration parameters of the second configuration file to determine the differing configuration items further includes:

[0051] Retrieve the first configuration parameters of multiple configuration items in the first configuration file, where the configuration parameters include the configuration item name, data type, value range, and configuration value;

[0052] Retrieve the second configuration parameters of multiple configuration items in the second configuration file;

[0053] Compare the first and second configuration parameters of multiple configuration items to determine the type of the differing configuration items.

[0054] The types of differential configuration items can include new configuration items, obsolete configuration items, modified configuration items, conflicting configuration items, and compatibility risk configuration items.

[0055] In one embodiment, after determining the difference configuration item by a preset identifier, the type of the difference configuration item can be determined by comparing the first configuration parameter and the second configuration parameter of multiple difference configuration items.

[0056] In some specific implementations, comparing the first and second configuration parameters of multiple configuration items to determine the type of the differing configuration item further includes:

[0057] Get the configuration item name in the first configuration parameter. If the configuration item name does not exist in the second configuration parameter, determine that the configuration item corresponding to the configuration parameter is the first difference configuration item.

[0058] When a configuration item name exists in the second configuration parameter, the data types in the first configuration parameter and the second configuration parameter are compared.

[0059] In response to data inconsistencies, the configuration item corresponding to the configuration parameter is determined as the second difference configuration item;

[0060] When the data types are consistent, compare the parameter ranges in the first configuration parameter and the parameter ranges in the second configuration parameter;

[0061] When the parameter ranges are consistent, the configuration item corresponding to the configuration parameter is determined as the second difference configuration item;

[0062] In response to inconsistent parameter ranges, determine whether the configuration value in the first configuration parameter is within the parameter range of the second configuration parameter;

[0063] If the configuration value in the first configuration parameter is within the parameter range of the second configuration parameter, the configuration item corresponding to the configuration parameter is determined to be the third difference configuration item;

[0064] If the configuration value in the first configuration parameter is not within the parameter range of the second configuration parameter, the configuration item corresponding to the configuration parameter is determined to be the fourth difference configuration item;

[0065] Obtain the configuration item name from the second configuration parameter. If the configuration item name does not exist in the first configuration parameter, determine that the configuration item corresponding to the configuration parameter is the fifth difference configuration item.

[0066] Here, the first difference configuration item can be an obsolete configuration item, meaning that the configuration item only exists in the first configuration file and not in the second configuration file.

[0067] Here, the second difference configuration item can be a conflicting configuration item, that is, the configuration items have the same name but different data types. For example, "SecureBoot" changes from a boolean type to an enumeration type.

[0068] Here, the third difference configuration item can be a modified configuration item, that is, the configuration item name is the same, the parameter range has changed, and the current configuration value falls into the updated parameter range.

[0069] Here, the fourth difference configuration item can be a compatibility risk configuration item, that is, the configuration item name is the same, the parameter range has changed, and the current configuration value does not fall within the updated parameter range.

[0070] Here, the fifth difference configuration item can be a newly added configuration item, that is, it only exists in the second configuration file and not in the first configuration file.

[0071] Specifically, the configuration parameters of each configuration item in the first configuration file and the second configuration file are compared in turn. First, the configuration items in the first configuration file are obtained, and then the matching configuration items in the second configuration file are obtained. After all the configuration items in the first configuration file have been compared, the unmatched configuration items in the second configuration file are obtained.

[0072] This allows for accurate identification of configuration change types and improves analysis efficiency.

[0073] In some specific implementations, the difference configuration items are processed according to the difference processing rules to obtain the target configuration file, including:

[0074] In response to the first difference configuration item being the first difference configuration item, the first difference configuration item is updated according to the preset mapping table to obtain the configuration item in the target configuration file;

[0075] When mapping cannot be performed through the preset mapping table, the first difference configuration item is updated to the default value and an alarm log is generated to obtain the configuration item in the target configuration file;

[0076] In response to the differential configuration item being the second differential configuration item, construct the decision elements;

[0077] Adjust the weights of decision-making factors based on historical data and user needs;

[0078] Based on the decision elements and weights, the scores of the second difference configuration items in the first configuration parameter and the second difference configuration items in the second configuration parameter are calculated and compared.

[0079] Use the second highest-scoring difference configuration item as the configuration item in the target configuration file;

[0080] In response to the fact that the difference configuration item is the third difference configuration item, the configuration item in the target configuration file is determined based on the first configuration parameter;

[0081] In response to the fact that the difference configuration item is the fourth difference configuration item, the parameter range in the second configuration parameter and the configuration value in the first configuration parameter are obtained;

[0082] By using a linear interpolation formula, the configuration values ​​in the first configuration parameter are mapped to the parameter range in the second configuration parameter to determine the configuration items in the target configuration file;

[0083] In response to the fifth differential configuration item, the configuration items in the target configuration file are determined based on the second configuration parameter.

[0084] Here, multiple processing rules can be combined into a multi-layered rule engine.

[0085] Among them, the first difference configuration item is replaced by a function based on a dynamic mapping table.

[0086] Specifically, the configuration items in the first configuration file are replaced with functionally equivalent configuration items according to the preset mapping table. The system automatically finds alternative items or generates compatibility warnings. If mapping is not possible, the default value of the configuration item in the second configuration file is used as the configuration value and an alarm log is generated.

[0087] For example, suppose the boot method in the first configuration file is Legacy Boot, and the second configuration file removes this method and changes it to UEFI Boot With CSM. If there is a preset mapping table rule, the old configuration item Legacy Boot = Enabled will be replaced with UEFI Boot with CSM=Enabled according to the mapping table. If there is no preset mapping table rule, the old item will be removed, replaced with the new option and default value, and a compatibility warning will be generated (e.g., configuration item).<Legacy Boot> (Obsted and with no alternative).

[0088] The second differential configuration item is processed using a weighted decision tree adjudication method.

[0089] The decision-making factors may include the source of the strategy, compliance risks, performance impact, and user history behavior.

[0090] Among them, the weight ratio of each decision element can be automatically adjusted based on the historical conflict resolution effect (such as the stability of the system after the decision).

[0091] Specifically, the weight ratio can be dynamically adjusted according to user needs.

[0092] Specifically, for the third difference configuration item, the configuration item in the first configuration file can be used as the configuration item in the target configuration file.

[0093] The fourth difference configuration item can be processed through linear interpolation formula mapping.

[0094] Specifically, based on the parameter range mapping, the configuration values ​​in the first configuration file are proportionally mapped to the parameter range in the second configuration file. The new configuration value can be obtained using the formula NewValue = (OldValue - OldMin) / (OldMax - OldMin) * (NewMax - NewMin) + NewMin.

[0095] For example, in the first configuration file, the user sets "CPU temperature threshold = 95℃", but in the second configuration file, due to changes in the heat dissipation design, the maximum temperature is limited to 90℃. The system performs parameter adaptation: 95℃ → 90℃, and generates logs.

[0096] Specifically, for the fifth difference configuration item, the configuration item in the second configuration file can be used as the configuration item in the target configuration file.

[0097] In one embodiment, it may further include: constructing a dependency graph based on configuration parameters, configuration item read / write dependencies, logical dependencies, binding relationships between configuration items and hardware resources, and service cascading dependencies; and processing the differential configuration items based on the dependency graph and in conjunction with differential processing rules.

[0098] Specifically, static configuration definitions are obtained by parsing firmware header files, which are used to extract configuration parameters of configuration items. Configuration access relationships are obtained through static code analysis, which are used to capture read and write dependencies of configuration items. Dynamic code records the access stack of configuration items to obtain runtime call chains, which are used to obtain implicit logical dependencies. Hardware resource mapping tables are obtained through device tree or chip manual parsing, which are used to establish the binding relationship between configuration items and hardware resources. Service startup dependencies are obtained by analyzing systemed units or initialization scripts, which are used to identify service cascading dependencies.

[0099] For example, when processing the first difference configuration item, the mapping table is combined with the dependency graph to obtain the mapping value of the first difference configuration item. When processing the fourth difference configuration item, the upstream and downstream relationships of the difference configuration item can be quickly identified through the dependency graph as a decision factor. In this way, the accuracy of configuration migration can be improved.

[0100] In this way, configuration lifecycle management is automated, cross-version compatibility is guaranteed, and a dynamic balance between security and flexibility is achieved.

[0101] In some specific implementations, the score of the second difference configuration item in the first configuration parameter and the score of the second difference configuration item in the second configuration parameter are calculated and compared based on the decision elements and weights, including:

[0102] Determine the priority of the second difference configuration item;

[0103] In response to the fact that the second difference configuration item belongs to the first priority, obtain the security configuration parameters corresponding to the second difference configuration item;

[0104] Calculate the scores for the security configuration parameters based on the decision-making factors and weights;

[0105] Compare the scores of the security configuration parameters, the scores of the second difference configuration items in the first configuration parameters, and the scores of the second difference configuration items in the second configuration parameters.

[0106] The first priority category includes configuration items corresponding to security policies. Specifically, the priority category may also include configuration items corresponding to security performance and configuration items corresponding to user interface preferences.

[0107] For example, assuming the configuration item is CPU overclocking, configuration value A in the first configuration file represents aggressive overclocking, configuration value B in the second configuration file represents allowing basic overclocking, and configuration value C in the security configuration parameter represents disabling overclocking. Decision factors include policy source, compliance risk, performance impact, and user history behavior, with weight coefficients of 0.6, 0.2, 0.15, and 0.05 for each factor. The policy source scores for A, B, and C are 0.3, 0.7, and 1.0, respectively; the compliance risk scores are 0 (non-compliant), 0.8 (compliant), and 0.8 (compliant); the performance impact scores are 0.8 (performance gain), 0.7 (performance balance), and 0 (performance loss); and the user history scores are 0.9 (frequent modifications), 0.3 (occasional modifications), and 0 (no history). According to the formula, the score for A is 0.345, the score for B is 0.7, and the score for C is 0.76. Therefore, the security configuration parameter is selected as the configuration parameter for the configuration item in the target configuration file.

[0108] In one embodiment, the weighting coefficients are optimized based on feedback from historical decision results. For example, if an enterprise frequently overrides security policies due to performance requirements, the weight of compliance risk is automatically increased.

[0109] In some specific implementations, the method further includes, prior to upgrading the basic input / output system firmware according to the target configuration file:

[0110] Obtain the target configuration file and perform conflict configuration detection on the target configuration file;

[0111] The test results are sent to the user so that the user can determine the appropriate course of action.

[0112] Specifically, the target configuration file is obtained, a migration simulation is pre-executed locally, the configuration is checked, a compatibility report is generated, and the user is prompted about the differences between the target configuration file and the first configuration file, allowing the user to determine whether to agree to the modification; if there are critical conflicts, the user is notified in advance to interrupt the upgrade or confirm the handling method.

[0113] In this way, configuration risks are exposed in advance, avoiding failures during the upgrade process.

[0114] In some specific implementations, the basic input / output system firmware is upgraded according to the target configuration file, including:

[0115] The target upgrade firmware is obtained based on the target configuration file and the preset firmware template;

[0116] Create a primary partition and a secondary partition, with the primary partition running the Basic Input / Output System firmware;

[0117] Write the target upgrade firmware to the spare partition, and perform a basic input / output system firmware upgrade based on the target upgrade firmware.

[0118] In response to an upgrade failure, an automatic rollback is triggered, restoring the firmware in the spare partition to the basic input / output system firmware.

[0119] Here, valid partitions are distinguished by identifiers. Specifically, the SPI Flash reserved area storage status identifier: 0x55AA indicates a valid primary partition, and 0xAA55 indicates a valid spare partition.

[0120] Specifically, during BIOS upgrade, the target upgrade firmware is written to the backup partition. If the upgrade is successful, the system attempts to boot from the backup partition. If boot is successful, the SPI Flash status identifier is updated (changing 0x55AA to 0xAA55), and the primary and backup partitions are switched. If the primary / backup switch is successful, the original primary partition is erased and a rollback image is written. The status identifier is updated, and the original primary partition is updated to the backup partition. If the upgrade fails (firmware flashing failure / boot timeout / POST verification error), the status identifier is restored to 0x55AA, invalid firmware in the backup partition is cleared, automatic rollback is triggered, and the backup partition is restored to the basic input / output system firmware.

[0121] This dual-partition design ensures that the system automatically rolls back to an available version in case of upgrade failure, reducing the problem of devices failing to boot due to upgrade interruptions and significantly improving operational efficiency and system reliability.

[0122] In one embodiment, the upgrade process may further include: S1, when the user modifies the configuration, automatically marking all non-default values, converting the binary configuration into structured JSON / XML format after modification, extracting key parameters to compare with the configuration definition files of the old and new firmware, and identifying new / deprecated / modified / conflicting / compatibility risk items; S2, modifying the options that differ between the old and new versions according to the version difference modification rules; S3, extracting the configuration template of the new firmware, performing a migration simulation locally, generating a compatibility report, prompting the user with inconsistent information, and notifying the user in advance to interrupt the upgrade or confirm the handling method if there is a key conflict; S4, adopting a dual-partition design, writing the new firmware to the backup partition and migrating the configuration during the upgrade, switching to the primary partition after successful verification, and automatically rolling back to the last available version if it fails.

[0123] In one embodiment, Figure 2 This is a schematic diagram of the upgrade process in the embodiments of this application, such as Figure 2As shown, the upgrade process in this application includes: obtaining the current firmware file, receiving user-modified configurations, marking user configuration items, parsing them into an A.xml file, obtaining the standard upgrade firmware file, parsing it into a B.xml file, comparing the A.xml file and the B.xml file to obtain configuration differences, modifying the configuration according to version differences to obtain the target configuration file, obtaining the target upgrade firmware file according to the firmware template, generating a compatibility report, prompting whether to upgrade, and if yes, performing the upgrade; otherwise, ending the upgrade.

[0124] In one embodiment, Figure 3 This is a schematic diagram of the dual-partition upgrade process in an embodiment of this application, as shown below. Figure 3 As shown, the dual-partition upgrade process in this application includes: upgrading the backup partition version A to version B, checking whether the upgrade is successful, if not, reverting the backup partition to version A, if yes, checking the primary partition version, if the primary partition version is B, ending the upgrade, if the primary partition version is A, switching the backup partition to the running partition, checking whether the switch is successful, if yes, running partition version B, if not, switching the running partition version A to the backup partition.

[0125] It should be understood that, although Figures 1-3 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figures 1-3 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0126] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method.

[0127] Embodiments of this application also provide a basic input / output system firmware upgrade apparatus. The cloud platform includes deployment nodes and at least one base node. The apparatus includes: a first processing module 401, used to acquire the current configuration data of the basic input / output system firmware, and perform a structured transformation on the current configuration data to obtain a first configuration file; a second processing module 402, used to acquire the upgrade configuration data of the basic input / output system standard upgrade firmware to obtain a second configuration file; a third processing module 403, used to compare the configuration parameters of the first configuration file and the configuration parameters of the second configuration file to determine the difference configuration items; and a fourth processing module 404, used to process the difference configuration items according to the difference processing rules to obtain a target configuration file, and perform a basic input / output system firmware upgrade according to the target configuration file.

[0128] As a preferred implementation, in this embodiment of the application, the first processing module 401 is specifically used to: parse the basic input / output system firmware, locate the configuration data area of ​​the basic input / output system firmware according to the configuration area identifier, and perform structured conversion on the configuration data in the configuration data area through a conversion tool to obtain a first configuration file.
