Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
The BIOS (basic input output system) is an important component in the server system, stores core parameters and programs for the server to run, and can guide the server to start. In order to improve the efficiency of managing the BIOS of the server, many manufacturers have introduced a Baseboard Management Controller (BMC) into the server. The baseboard management controller can remotely manage the BIOS, and work efficiency in a server manager can be improved.
In the related art, the BIOS acquires the out-of-band BIOS start parameter from a Baseboard Management Controller (BMC) during the start-up process and updates the memory, but in order to enable the out-of-band BIOS start parameter in the memory to take effect, the BIOS needs to perform an additional restart operation, which reduces the setting efficiency of the BIOS start parameter, and also reduces the work efficiency of the server administrator due to the restart. In view of the above, the present invention provides a BIOS parameter setting method, which enables a BIOS to obtain an out-of-band BIOS start parameter from a baseboard management controller and set the out-of-band BIOS start parameter to be valid at a PEI (Pre-EFI Initialization) stage of the BIOS Initialization start parameter, so as to ensure that the out-of-band BIOS start parameter is valid at the PEI stage, and effectively avoid the restart problem in the BIOS parameter setting process in the related art. Referring to fig. 1, fig. 1 is a method for setting BIOS parameters according to an embodiment of the present invention, where the method includes:
s101, when the BIOS is in a PEI stage, obtaining out-of-band BIOS starting parameters from a baseboard management controller.
In the related art, when the BIOS is started, the BIOS start parameter is initialized by using the historical BIOS start parameter stored in the memory, and when the initialization is finished, the out-of-band BIOS start parameter is acquired from the baseboard management controller, and the historical BIOS start parameter in the memory is updated by using the out-of-band BIOS start parameter. The historical BIOS starting parameters are variables and corresponding variable values required by BIOS starting, and the out-of-band BIOS starting parameters are BIOS starting variables and corresponding variable values which are stored in the substrate management controller and are updated and set by server management personnel. Because the BIOS has completed initialization of the start parameter, if the updated historical BIOS start parameter in the memory needs to be validated, the BIOS needs to be restarted to re-read and initialize the updated historical BIOS start parameter in the memory, so in the related art, there is an additional restart operation for setting the BIOS start parameter, and the restart operation not only reduces the setting efficiency of the BIOS start parameter, but also reduces the work efficiency of the server administrator, and brings inconvenience to the work of the administrator.
In the embodiment of the present invention, the BIOS may obtain the out-of-band BIOS start parameter from the bmc at a PEI (Pre-EFI Initialization) stage of the BIOS start-up procedure, and the PEI is the BIOS start-up parameter Initialization procedure in the BIOS start-up procedure. That is to say, the BIOS of the present invention can obtain the out-of-band BIOS start parameter from the bmc in the BIOS start parameter initialization step and set the out-of-band BIOS start parameter, so as to ensure that the out-of-band BIOS start parameter becomes valid in the BIOS start parameter initialization step, and it is not necessary to read the memory again, thereby avoiding an additional restart problem in the setting of the BIOS start parameter in the related art, effectively improving the efficiency of setting the BIOS start parameter, and finally improving the work efficiency of the server administrator.
It should be noted that, the embodiment of the present invention does not limit specific historical BIOS startup parameters and out-of-band BIOS startup parameters, and a user may refer to a related technique of the BIOS startup parameters. It can be understood that, in order to accurately initialize by using the historical BIOS startup parameters, the historical BIOS startup parameters may have MapID of a unique identification variable; similarly, in order to accurately update the historical BIOS startup parameters by using the out-of-band BIOS startup parameters, the out-of-band BIOS startup parameters may also have MapID with a unique identification variable, so that the historical BIOS startup parameters may be accurately searched and updated. It should be noted that, the invention does not limit whether the out-of-band BIOS startup parameter needs to include all the historical BIOS startup parameters or only needs to include part of the historical BIOS startup parameters, and when each historical BIOS startup parameter needs to be updated, the out-of-band BIOS startup parameter may include all the historical BIOS startup parameters; when only a portion of the historical BIOS start-up parameters need to be updated, the out-of-band BIOS start-up parameters may also only include a portion of the historical BIOS start-up parameters. In the embodiment of the invention, considering that the number of the historical BIOS starting parameters is large, a large amount of time is consumed for updating all the historical BIOS starting parameters, so that the out-of-band BIOS starting parameters only need to contain part of the historical BIOS starting parameters. It should be noted that, the embodiment of the present invention also does not limit the specific memory for storing the historical BIOS start parameters, and the user can set the historical BIOS start parameters according to the actual application requirements. In one case, the Memory may be an NVRAM (Non-Volatile Random Access Memory), a type of Memory that retains data after power is removed.
Further, the embodiment of the present invention does not limit the specific process of the BIOS obtaining the out-of-band BIOS start parameter from the bmc, and the user may refer to the related technology of IPMI (Intelligent Platform Management Interface), which is an industrial standard for monitoring the physical health characteristics of the server. In a possible case, since the bmc cannot actively communicate with the BIOS, the BIOS sends an IPMI command to the bmc, and the bmc responds the IPMI command, so that the process of obtaining the out-of-band BIOS start parameter from the bmc may include:
step 11: sending an IPMI command indicating that an out-of-band BIOS starting parameter is requested to a baseboard management manager;
step 12: and receiving the out-of-band BIOS starting parameters sent by the baseboard management controller.
It should be noted that, the embodiment of the present invention does not limit the specific IPMI command for requesting the out-of-band BIOS start parameter, as long as the command adopts the data form of the IPMI command, and the command may accurately carry the request for the out-of-band BIOS start parameter, and the user may set the command by combining the related technologies. The embodiment of the invention also does not limit the mode that the baseboard manager sends the out-of-band BIOS starting parameter, and the user can refer to the IPMI technology. The embodiment of the present invention also does not limit the form in which the baseboard management controller sends the out-of-band BIOS start-up parameters, for example, the baseboard management controller can send the out-of-band BIOS start-up parameters one by one, and can also encapsulate the BIOS start-up parameters to be sent into a JSON file to send them uniformly, where JSON (JavaScript Object notification) is a lightweight data exchange format. In consideration of the fact that sending out-of-band BIOS boot parameters one by one is not only low in transmission efficiency, but also more prone to cause a sending failure compared with unified sending due to a large number of sending times, in the embodiment of the present invention, the baseboard management controller may encapsulate the out-of-band BIOS boot parameters to be sent into the JSON file for unified sending.
Further, it should be noted that, the embodiment of the present invention does not limit whether a handover data block list needs to be created, and stores the out-of-band BIOS start parameter into the handover data block list, and starts a handover data block (HOB, hand-off Blocks) for transferring data information required by the BIOS from a PEI phase to a DXE (Driver Execution Environment) phase, and may temporarily store the out-of-band BIOS start parameter; when the out-of-band BIOS start-up parameters are received by the BIOS and can be used for updating the historical BIOS start-up parameters, the out-of-band BIOS start-up parameters do not need to be stored in the handover data block list; when the out-of-band BIOS startup parameter needs to be analyzed and extracted and then can be used to update the historical BIOS startup parameter, the out-of-band BIOS startup parameter may also be stored in the handover data block list. The substrate management controller of the embodiment of the invention adopts the JSON format to uniformly send the out-of-band BIOS starting parameters, and further analyzes the JSON file, so that the out-of-band BIOS starting parameters can be stored in the handover data block list.
In one possible case, the process of obtaining the out-of-band BIOS boot parameters from the baseboard management controller may include:
step 21: acquiring out-of-band BIOS starting parameters from a substrate management controller;
step 22: and creating a handover data block list, and saving the out-of-band BIOS starting parameters into the handover data block list.
It should be noted that the embodiment of the present invention does not limit the specific way to create the handover data block list, and the user may refer to the related art of handover data block HOB.
S102, obtaining historical BIOS starting parameters, and updating the historical BIOS starting parameters by using the out-of-band BIOS starting parameters.
It is understood that the historical BIOS startup parameters obtained in this step are all the BIOS startup parameters required for initializing the BIOS startup parameters, and the historical BIOS startup parameters are obtained by the BIOS from the memory. It should be noted that, because the BIOS can only execute an operation of reading the memory at the PEI stage, and cannot perform a write operation on the memory, in this step, the out-of-band BIOS startup parameter is used to update the historical BIOS startup parameter as follows: and updating the historical BIOS starting parameters obtained from the memory by using the out-of-band BIOS starting parameters. That is, in this step, the historical BIOS start parameters stored in the memory are not updated and modified.
It should be noted that the embodiment of the present invention does not limit the specific manner and process of updating the historical BIOS start-up parameters by using the out-of-band BIOS start-up parameters, for example, the GetVariable () function for obtaining the historical BIOS start-up parameters, which obtains the historical BIOS start-up parameters, may be repackaged, and in the repackaged obtained function, the historical BIOS start-up parameters corresponding to the out-of-band BIOS start-up parameters are searched, and the values of the historical BIOS start-up parameters corresponding to the out-of-band BIOS start-up parameters are compared, if the two are the same, the historical BIOS start-up parameters are retained, and if the two are different, the corresponding historical BIOS start-up parameters are replaced by the out-of-band BIOS start-up parameters; certainly, the update function can also be customized, the history BIOS start parameters returned by the function are extracted and obtained by using the customized update function, the update process is performed by using the out-of-band BIOS start parameters as the corresponding history BIOS start parameters, and the user can set the update function according to the actual application requirements. Considering that the GetVariable () for obtaining the BIOS startup parameters is a native function of the BIOS system, repackaging the function, and updating the historical BIOS startup parameters by using the repackaged function and the out-of-band BIOS startup parameters, which does not disturb the original functions of the BIOS and can also update the historical BIOS startup parameters more efficiently.
And S103, initializing BIOS starting parameters of a PEI stage by using the updated historical BIOS starting parameters.
After the update is completed, the variable value of the out-of-band BIOS starting parameter is written into the updated historical BIOS starting parameter, and the updated historical BIOS starting parameter is utilized to carry out BIOS starting parameter initialization in the PEI stage, so that the out-of-band BIOS starting parameter can be ensured to be effective in the PEI stage without reading the memory again, the problem that the out-of-band BIOS starting parameter can be effective only by additionally restarting in the related art can be effectively solved, the setting efficiency of the BIOS starting parameter is effectively improved, and the working efficiency of a server administrator can be improved. It should be noted that, in the embodiment of the present invention, a specific process of initializing the BIOS start parameter in the PEI phase is not limited, and a user may refer to a related technology of PEI.
Furthermore, the embodiment of the invention does not limit whether the historical BIOS starting parameters in the memory need to be updated by using the out-of-band BIOS starting parameters at other stages of the BIOS starting link, and when the BIOS does not store the latest BIOS starting parameters, the latest out-of-band BIOS starting parameters are acquired from the substrate management controller every time, and meanwhile, when the BIOS can also ensure higher starting efficiency, the historical BIOS starting parameters in the memory can not be updated; when the update frequency of the out-of-band BIOS start-up parameter is low, or the start-up efficiency of the BIOS needs to be improved, or the BIOS start-up parameter used for initialization needs to be ensured to be consistent with the historical BIOS start-up parameter in the memory, the historical BIOS start-up parameter in the memory can be updated by using the out-of-band BIOS start-up parameter at the BDS stage of the BIOS start-up link. In view of the fact that it is required to ensure that the BIOS startup parameters used for initialization are consistent with the historical BIOS startup parameters in the memory, and the update frequency of the out-of-band BIOS startup parameters is low, the BIOS updates the out-of-band BIOS startup parameters into the memory, and it is also possible to avoid the need for updating the historical BIOS startup parameters with the out-of-band BIOS startup parameters during each BIOS startup. The present invention does not limit at which other phase in the BIOS Boot link the operation of updating the historical BIOS Boot parameters in the memory is located, for example, the DXE phase and the BDS phase after the PEI phase, where the DXE (Driver Execution Environment) phase is a hardware Driver initialization phase on the server, and the BDS (Boot Device Selection) is a Selection phase of the Boot Device, and all initialization of the BIOS Boot parameters and initialization of the hardware drivers are completed in the BDS phase. In consideration of the fact that the BDS stage has completed initialization of all BIOS startup parameters and hardware drivers, that is, the out-of-band BIOS startup parameters can take effect completely, the embodiment of the present invention may update the historical BIOS startup parameters in the memory by using the out-of-band BIOS startup parameters in the BDS stage.
Based on the above embodiments, the BIOS in the method acquires the out-of-band BIOS start-up parameter from the board management controller at a PEI phase (Pre-EFI Initialization, wake-up CPU and memory Initialization phase), and since the PEI phase is a phase at which the BIOS initializes the start-up parameter, the BIOS of the present invention can directly update the history BIOS start-up parameter at the BIOS start-up parameter Initialization phase by using the out-of-band BIOS start-up parameter acquired from the board management controller, and complete the BIOS start-up parameter Initialization at the PEI phase by using the updated BIOS start-up parameter, so that the out-of-band BIOS start-up parameter can be validated at the PEI phase of the BIOS without re-reading the memory, thereby effectively avoiding the restart problem of the related art at the BIOS parameter setting step, effectively improving the setting efficiency of the BIOS start-up parameter, and finally improving the work efficiency of the server administrator.
Based on the above embodiments, another BIOS parameter setting method provided in the embodiments of the present invention is described below. Referring to fig. 2, fig. 2 is a flowchart of another BIOS parameter setting method according to an embodiment of the present invention, where the method includes:
s201, when the BIOS is in a PEI stage, obtaining out-of-band BIOS starting parameters from the baseboard management controller.
S202, obtaining historical BIOS starting parameters, and updating the historical BIOS starting parameters by using the out-of-band BIOS starting parameters.
And S203, initializing BIOS starting parameters of a PEI stage by using the updated historical BIOS starting parameters.
The definition of steps S201 to S203 is the same as that of the above embodiment, and is not described again here.
And S204, when the BIOS is in the BDS stage, updating the historical BIOS starting parameters in the memory by using the out-of-band BIOS starting parameters.
Because the initialization of all the BIOS starting parameters and the hardware drive is completed in the BDS stage, namely the out-of-band BIOS starting parameters can be completely effective, the embodiment of the invention can update the historical BIOS starting parameters in the memory by using the out-of-band BIOS starting parameters in the BDS stage so as to ensure that the historical BIOS starting parameters in the memory are consistent with the BIOS starting parameters which are actually initialized.
It should be noted that, the embodiment of the present invention does not limit the obtaining location of the out-of-band BIOS start parameter in step 204, for example, the out-of-band BIOS start parameter may be obtained from the bmc again, or the out-of-band BIOS start parameter may be extracted from the handover data block list when the BIOS stores the out-of-band BIOS start parameter to the handover data block list in the PEI phase. Since the out-of-band BIOS start parameter in the handover data block list directly participates in the initialization of the BIOS start parameter, in order to ensure that the initialized BIOS start parameter is consistent with the historical BIOS start parameter in the memory, in the embodiment of the present invention, the out-of-band BIOS start parameter is extracted from the handover data block list.
In a possible case, the updating the historical BIOS startup parameters in the memory using the out-of-band BIOS startup parameters may include:
step 31: extracting out-of-band BIOS starting parameters from the handover data block list;
step 32: and updating the historical BIOS starting parameters in the memory by using the out-of-band BIOS starting parameters.
It should be noted that, the embodiment of the present invention does not limit the specific method and process for extracting the out-of-band BIOS startup parameter from the handover data block list and updating the historical BIOS startup parameter in the memory by using the out-of-band BIOS startup parameter, for example, a callback function for setting a variable value at the BDS stage may be registered, the out-of-band BIOS startup parameter in the handover data block list is read by using the callback function, the historical BIOS startup parameter in the memory is updated by using the historical BIOS startup parameter setting function SetVariable () of the BIOS, the historical BIOS startup parameter setting function SetVariable () of the BIOS may be repackaged, the out-of-band BIOS startup parameter in the out-of-band handover data block list is extracted by using the repackaged historical BIOS startup parameter setting function, and finally the historical BIOS startup parameter in the memory is updated by using the historical BIOS startup parameter.
And S205, sending the updated historical BIOS starting parameters in the memory to the baseboard management controller.
The step aims to synchronize the historical BIOS starting parameters which are initialized and updated in the BIOS into the baseboard management controller so as to ensure that the historical BIOS starting parameters in the memory are consistent with records in the baseboard management controller.
It should be noted that the embodiment of the present invention does not limit a specific sending manner for sending the updated historical BIOS startup parameter in the memory to the baseboard management controller, for example, the updated historical BIOS startup parameter in the memory may be sent to the baseboard management controller in the form of an IPMI command, or the updated historical BIOS startup parameter in the memory may be sent to the baseboard management controller by using a USB LAN wired network card of Redfish, where Redfish is a management standard based on HTTPs service, and may perform fast file transfer. Because the file transmission rate of Redfish is high, the updated historical BIOS starting parameters in the memory can be sent to the baseboard management controller by using the USB LAN of Redfish.
Further, it is considered that an update error may occur in the process of updating the historical BIOS start-up parameter in the memory by using the out-of-band BIOS start-up parameter, and at this time, the out-of-band BIOS start-up parameter is not written into the memory, so that inconsistency between the historical BIOS start-up parameter in the memory and the actually initialized BIOS start-up parameter may be generated. In order to prompt the server administrator to reset the BIOS parameter, in the process of updating the historical BIOS startup parameter in the memory by using the out-of-band BIOS startup parameter, the out-of-band BIOS startup parameter with the update error may be recorded, so as to provide the server administrator with failure recording information.
In one possible case, the process of updating the historical BIOS start parameters in the memory using the out-of-band BIOS start parameters may include:
step 41: updating the historical BIOS starting parameters in the memory by using the out-of-band BIOS starting parameters;
step 42: when the out-of-band BIOS starting parameter has an update error, storing the out-of-band BIOS starting parameter with the update error into failure log data;
step 43: and sending the failure log data to a baseboard management controller.
It should be noted that, in the embodiment of the present invention, specific data content included in the failure log data is not limited, for example, the data content may include an out-of-band BIOS start parameter with an update error and a corresponding numerical value, may also include a unique variable identifier MapID corresponding to the out-of-band BIOS start parameter with an update error, and may also include a failure identifier of the out-of-band BIOS start parameter with an update error, and a user may set the failure identifier according to actual application requirements. It should be noted that the limited description of the sending method for sending the failure log data to the baseboard management controller is consistent with the limited description of the sending method for sending the updated historical BIOS startup parameters in the memory to the baseboard management controller, and details are not described here.
Of course, when the update error occurs in the out-of-band BIOS start parameter, the memory update operation may be executed again by using the out-of-band BIOS start parameter, so as to eliminate the interference of the accidental situation on the memory update operation. When the same out-of-band BIOS starting parameter has an update error repeatedly, because the out-of-band BIOS starting parameter has an abnormal condition, in order to not affect the update of other out-of-band BIOS starting parameters, when the failure times of the same out-of-band BIOS starting parameter reach the preset times, the memory update operation of the out-of-band BIOS starting parameter is stopped, and the out-of-band BIOS starting parameter is recorded into the failure log data.
In one possible case, before saving the out-of-band BIOS start parameter of the update error into the failure log data, the method may further include:
step 51: and re-executing the operation of updating the historical BIOS starting parameters in the memory by using the out-of-band BIOS starting parameters until the error times of the out-of-band BIOS starting parameters with the errors are up to the preset times, and recording the out-of-band BIOS starting parameters with the errors to the failure log data.
It should be noted that, the embodiment of the present invention does not limit the specific value of the preset times, and the user may set the preset times according to the actual application requirement.
Based on the embodiment, after the BIOS completes initialization of the BIOS starting parameters in the PEI stage, the BIOS updates historical BIOS starting parameters in the memory by using the out-of-band BIOS starting parameters in the BDS stage, and the memory updating operation can ensure that the historical BIOS starting parameters in the memory are consistent with the BIOS starting parameters initialized actually so as to ensure that the BIOS starting parameters used by the BIOS are consistent; meanwhile, after the updating is finished, the method also sends the updated historical BIOS starting parameters in the memory to the substrate management controller, so that the historical BIOS starting parameters in the memory can be ensured to be consistent with records in the substrate management controller.
The procedure of setting the BIOS parameters described above is explained below with reference to a specific example. In one possible case, the process of setting the BIOS parameter may include:
1. the method comprises the steps that the BIOS sends an IPMI command requesting out-of-band BIOS starting parameters to a Baseboard Management Controller (BMC) at a PEI stage of a starting link, and receives an out-of-band BIOS starting parameter BIOS _ future _ settings.json file sent by the BMC;
2. analyzing a Bios _ future _ settings.json file, creating a handover data block list HOB, and storing the analyzed out-of-band Bios start-up parameters;
3. repackaging a historical BIOS starting parameter acquisition function GetVariable () of a BIOS native function, acquiring historical BIOS starting parameters and out-of-band BIOS starting parameters in the HOB by utilizing the repackaged GetVariable (), and updating the historical BIOS starting parameters by utilizing the out-of-band BIOS starting parameters;
4. the updated historical BIOS starting parameters are used for completing initialization of the BIOS starting parameters of the PEI stage;
5. setting a callback function by using a preset variable in the BDS, acquiring an out-of-band BIOS starting parameter stored in the HOB, and updating the historical BIOS starting parameter in the NVRAM memory by using the out-of-band BIOS starting parameter through a setting function SetVariable () function of the historical BIOS starting parameter of a BIOS native function;
