Description
Technical Field
The invention belongs to the technical field of BIOS firmware updating, and particularly relates to a method and a device for realizing retention of BIOS upgrading and downgrading configuration options.
Background
With the continuous popularization and development of server technology, the performance, function and usability of a server are continuously enhanced, BIOS Setup in the server has more and more configuration options, and different clients can configure different option combinations according to their business requirements, but often face the following problems in the setting process: after the options of a plurality of nodes on an on-line or production line are set, the BIOS needs to be updated and refreshed, the original setting operation of the options needs to be carried out again, and the configuration efficiency is influenced by manpower. And secondly, after the configuration is finished, whether the setting state of the option is correct needs to be checked.
The retention of BIOS options is currently done by two schemes. The first is to use AFU tool to reserve BIOS option when in-band refresh, in this scheme, because option variable is located in NVRAM of BIOS, the refresh of this area can be skipped according to the refresh command, to realize the reservation of BIOS option, but when the option layout of the two versions before and after BIOS changes, the function of reserving parameter can not be realized, and the whole BIOS area must be refreshed forcibly. The second is to reserve BIOS options based on redfish technology, in the scheme, a BMC can store an option set json file generated after the options are set, after the BIOS is updated, the BIOS can synchronize the json file according to a condition for refreshing reserved parameters in the boot process, and update option variables in a BIOS NVRAM (random access memory), so that the BIOS options can be reserved.
Therefore, it is desirable to provide a method and an apparatus for implementing BIOS upgrade configuration option retention to overcome the above-mentioned shortcomings in the prior art.
Disclosure of Invention
Aiming at the application scene of partial configuration option modification in the prior art, the prior mode of using an AFU tool cannot reserve option parameters when the layout changes before and after BIOS refreshing, and the prior scheme of adopting a redfish technology has the defect that the stability of a product is reduced by a module needing to be introduced.
In a first aspect, the present invention provides a method for implementing BIOS upgrade configuration option reservation, including the following steps:

s3, after learning the flag bit position of the first data structure body, the BIOS reads configuration option data from the first data structure body, sets configuration option modification data into the BIOS, cancels the flag bit position of the first data structure body, and executes restarting;
s4, the BIOS acquires the current configuration option data of the BIOS and sends the current configuration option data to the BMC to be stored in a second data structure;
s5, carrying out BIOS firmware refreshing for reserving the configuration option data through the AFU tool in the band and the BMC in the out-of-band, verifying the correctness of a refreshing result, copying the data in the second data structure of the BMC into the first data structure, and setting the flag bit of the first data structure.

and S22, the BMC stores the configuration options and the modification data which need to be modified into the first data structure body, and sets the flag bit of the first data structure body. A flag bit in the first data structure is used to indicate whether a BIOS configuration option needs to be modified.
Further, the step S3 specifically includes the following steps:
s31, after the BIOS is started, reading a zone bit from a first data structure of the BMC through an IPMI reading command, and judging whether the zone bit is set;

s34, the BMC checks whether the flag bit in the first data structure body is set;
if yes, go to step S4;
if not, the data in the first data structure body is cleared. After the BIOS is started, whether the configuration option modification is needed or not is judged through the flag bit of the first data structure body, when the modification is needed, the configuration option modification data is obtained to modify the BIOS configuration option, and after the modification is finished, the setting of the flag bit is cancelled, so that the follow-up misjudgment is prevented.
Further, the step S4 includes the following steps:
s41, the BIOS collects the current configuration option data of the BIOS and sends the current configuration option data to the BMC through an IPMI setting command;

and S413, creating a temporary structural body by the BMC, storing the data in the option combination structural body, and acquiring a data value in the option combination structural body through the offset, so as to obtain the current configuration option data of the BIOS. The option combination structure body and the temporary structure body realize the butt joint of the BIOS and the data in the data structure body in the BMC.
Further, the step S5 specifically includes the following steps:
s51, judging whether in-band refreshing or out-of-band refreshing is performed on the BIOS;
if so, go to step S52;
if no, go to step S54;
s52, under an operating system, a user sends an IPMI command to the BMC in a band;

s55, copying the data in the second data structure body into the first data structure body by the BMC, setting the flag bit of the first data structure body, and informing the BIOS to execute firmware refreshing;
and S56, verifying the correctness of the refreshing result by the BMC. Whether the out-of-band refreshing or the in-band refreshing is carried out, the current configuration data in the second structural body is stored in the first data structural body, the zone bit of the first data structural body is located, and the BIOS configuration option is considered to be modified, so that the BIOS keeps the original configuration option to be effective, and the stability is improved.
Further, the step S56 specifically includes the following steps:
s561, after the BIOS firmware is refreshed, entering an operating system;
s562, the BMC acquires configuration option data in the second data structure, performs CRC calculation and generates first check data;
s563, the BMC acquires the current BIOS configuration option data through an IPMI command, and performs CRC calculation to generate second check data;
