Description

Technical Field

[0001] The present invention relates to the field of BIOS, and in particular to a BIOS upgrade method, system, device, and storage medium. Background Art

[0002] During the operation and maintenance of servers, it is often necessary to upgrade the BIOS (Basic Input Output System) image in - band.

[0003] Previously, the in - band BIOS upgrade method for Open POWER servers was mainly based on the ipmi (Intelligent Platform Management Interface) protocol. By sending the BIOS image in segments to the BMC (Baseboard Management Controller), the BMC then writes it into the BIOS image Flash (flash memory) to achieve BIOS image update. However, this method can only write to the Flash at a fixed segment length. If the writing is interrupted in the middle, it will cause the image in the Flash to be damaged. Once the image in the Flash is damaged, the previous BIOS image cannot be restored. Moreover, this method is complex to implement, and the refresh program cannot be exited until the BIOS image is completely written into the Flash, resulting in low efficiency. Summary of the Invention

[0004] In view of this, in order to overcome at least one aspect of the above problems, an embodiment of the present invention provides a BIOS upgrade method, including the following steps: In response to receiving an upgrade instruction, the host updates a preset register to a first state; In response to the BMC detecting that the preset register is in the first state, a temporary folder is created and the preset register is updated to a second state; In response to the host detecting that the preset register is in the second state, the BIOS file to be upgraded is sent to the temporary folder, and after the sending is completed, the preset register is updated to a third state; In response to the BMC detecting that the preset register is in the third state, the BMC upgrades the BIOS using the BIOS file to be upgraded in the temporary folder.

[0005] In some embodiments, the BMC upgrades the BIOS using the BIOS file to be upgraded in the temporary folder, further including: The BMC updates the preset register to a fourth state; In response to the host detecting that the preset register is in the fourth state, a restart is performed; When the host restarts, the BMC recombines the BIOS file to be upgraded in the temporary folder into a BIOS image file and writes it into the BIOS Flash.

[0006] In some embodiments, before the host updates the preset register to the first state, it further includes: Dividing the BIOS image file into multiple sub-files; Displaying the name and detailed information description of each of the sub-files.

[0007] In some embodiments, in response to the host detecting that the preset register is in the second state, when sending the BIOS file to be upgraded to the temporary folder, it further includes: According to the upgrade instruction, sending several sub-files to be upgraded selected by the user to the temporary folder.

[0008] In some embodiments, it further includes: In response to the host not detecting that the BMC updates the preset register to the second state within a preset time period, updating the preset register to the fifth state.

[0009] In some embodiments, it further includes: In response to the host not detecting that the BMC updates the preset register to the fourth state within a preset time period, updating the preset register to the fifth state.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] To make the objectives, technical solutions, and advantages of the present invention more clear and understandable, the following further elaborates on the embodiments of the present invention in detail with reference to specific embodiments and the accompanying drawings.

[0018] It should be noted that all the expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two entities or parameters with the same name but different identities. It can be seen that "first" and "second" are only for the convenience of expression and should not be construed as a limitation on the embodiments of the present invention. This will not be elaborated one by one in the subsequent embodiments.

[0019] According to one aspect of the present invention, an embodiment of the present invention provides a BIOS upgrade method, as Figure 1 shown, which may include the steps: S1. In response to receiving an upgrade instruction, the host updates a preset register to a first state; S2. In response to the BMC detecting that the preset register is in the first state, create a temporary folder and update the preset register to a second state; S3. In response to the host detecting that the preset register is in the second state, send the BIOS file to be upgraded to the temporary folder, and after the sending is completed, update the preset register to a third state; S4. In response to the BMC detecting that the preset register is in the third state, the BMC upgrades the BIOS using the BIOS file to be upgraded in the temporary folder.

[0020] The solution proposed by the present invention sets a preset register for identifying the upgrade status, marks the current update status by modifying the value of the preset register, and then separates the updated BIOS image file from the BIOS image file running in the BMC. When the Host restarts, the BMC upgrades the BIOS image file. In this way, it can be determined whether the BIOS image has been upgraded successfully. Only when the upgrade is completed, the BIOS image file is actually updated. In case of an upgrade failure, the BMC can easily restore the previous BIOS image.

[0021] In some embodiments, the BMC upgrades the BIOS using the BIOS file to be upgraded in the temporary folder, which further includes: The BMC updates the preset register to a fourth state; In response to the host detecting that the preset register is in the fourth state, perform a restart; When the host restarts, the BMC reorganizes the BIOS file to be upgraded in the temporary folder into a BIOS image file and writes it into the BIOS Flash.

[0022] Specifically, as Figure 2 shown, after receiving the upgrade instruction, the Host changes the state of the preset register to start the upgrade (the first state). After the BMC receives the change in the state of the preset register, it performs pre-upgrade preparation work, creates a temporary folder to store the upgraded BIOS file, and then changes the state of the preset register to start (the second state). After the host sends the BIOS file to be upgraded to the BMC, the BMC stores the received file in the temporary folder, and then the host updates the state of the preset register to sent complete (the third state). At this time, if the BMC detects that the state of the preset register is the third state, it updates it to end (the fourth state), indicating that the upgrade is complete. After the upgrade is complete, the BMC waits for the Host to restart. When the Host restarts, the BMC reorganizes the files in the temporary folder into a BIOS image and writes it to the BIOS Flash.

[0023] In some embodiments, before the host updates the preset register to the first state, it further includes: Dividing the BIOS image file into multiple sub-files; Displaying the name and detailed information description of each of the sub-files.

[0024] In some embodiments, in response to the host detecting that the preset register is in the second state and sending the BIOS file to be upgraded to the temporary folder, it further includes: Sending several sub-files to be upgraded selected by the user to the temporary folder according to the upgrade instruction.

[0025] Specifically, as Figure 3 shown, the BIOS Image can be split into multiple Parts according to its logical structure and placed in the database. After the splitting is completed, the help information of the split Parts is retrieved from the database, and the Part names and corresponding Help information of the BIOS Image to be upgraded this time are displayed. The user can choose which Parts to keep or refresh, and then send them to the BMC.

[0026] In some embodiments, the interaction between the host, the preset register, and the BMC can be implemented based on PLDM commands.

[0027] In some embodiments, it further includes: In response to the host not detecting that the BMC updates the preset register to the second state within a preset time period, updating the preset register to the fifth state.

[0028] In some embodiments, it further includes: In response to the host not detecting that the BMC updates the preset register to the fourth state within a preset time period, update the preset register to the fifth state.

[0029] Specifically, as Figure 2 shown, if the BMC fails to modify the state due to timeout, for example, fails to update the preset register to the second state due to timeout, or fails to update the preset register to the fourth state due to timeout, the host will update the preset register to ABORT (the fifth state).

[0030] In some embodiments, it further includes: In response to the BMC detecting that the preset register is in the fifth state, delete the temporary folder.

[0031] Specifically, if the upgrade process times out or fails, the BMC directly deletes the content in the Staging folder and waits for the next upgrade, so as not to affect the original un-upgraded image in the BIOS Flash. Or whether the Host shuts down during the upgrade process or there is a forced power-off, the current upgrade is terminated and the BMC does not retain the content in the Staging folder.

[0032] The solution proposed by the present invention sets a preset register for identifying the upgrade state, marks the current update state by modifying the value of the preset register, and then separates the updated BIOS image file from the BIOS image file running in the BMC. When the Host restarts, the BMC upgrades the BIOS image file again. In this way, it can be determined whether the BIOS image has been upgraded successfully. Only when the upgrade is completed, the BIOS image file is actually updated. In case of upgrade failure, the BMC can conveniently restore the previous BIOS image.

[0033] Based on the same inventive concept, according to another aspect of the present invention, an embodiment of the present invention further provides a BIOS upgrade system 400, as Figure 4 shown, including a host 401 and a BMC 402, wherein: The host 401 is configured to update the preset register to the first state in response to receiving an upgrade instruction; The BMC 402 is configured to create a temporary folder and update the preset register to the second state in response to detecting that the preset register is in the first state; The host 401 is further configured to send the BIOS file to be upgraded to the temporary folder in response to detecting that the preset register is in the second state, and update the preset register to the third state after the sending is completed; The BMC 402 is further configured to upgrade the BIOS by using the BIOS file to be upgraded in the temporary folder in response to detecting that the preset register is in the third state.

[0034] The solution proposed by the present invention sets a preset register for identifying the upgrade status, marks the current update status by modifying the value of the preset register, and then separates the updated BIOS image file from the BIOS image file running in the BMC. When the Host restarts, the BMC upgrades the BIOS image file, so that it can be determined whether the BIOS image upgrade is completed. Only when the upgrade is completed, the BIOS image file is actually updated. In case of upgrade failure, the BMC can easily restore the previous BIOS image.

[0035] In some embodiments, the BMC upgrades the BIOS by using the BIOS file to be upgraded in the temporary folder, further including: The BMC updates the preset register to the fourth state; In response to the host detecting that the preset register is in the fourth state, it performs a restart; When the host restarts, the BMC reorganizes the BIOS file to be upgraded in the temporary folder into a BIOS image file and writes it into the BIOS Flash.

[0036] In some embodiments, before the host updates the preset register to the first state, it further includes: Dividing the BIOS image file into multiple sub-files; Displaying the name and detailed information description of each sub-file.

[0037] In some embodiments, in response to the host detecting that the preset register is in the second state, sending the BIOS file to be upgraded to the temporary folder, further including: According to the upgrade instruction, sending several sub-files selected by the user to be upgraded to the temporary folder.

[0038] In some embodiments, it further includes: In response to the host not detecting that the BMC updates the preset register to the second state within a preset time period, updating the preset register to the fifth state.

[0039] In some embodiments, it further includes: In response to the host not detecting that the BMC updates the preset register to the fourth state within a preset time period, updating the preset register to the fifth state.

[0040] In some embodiments, it further includes: In response to the BMC detecting that the preset register is in the fifth state, deleting the temporary folder.

[0041] The solution proposed by the present invention sets a preset register for identifying the upgrade status, marks the current update status by modifying the value of the preset register, and then separates the updated BIOS image file from the BIOS image file running in the BMC. When the Host restarts, the BMC upgrades the BIOS image file. In this way, it can be determined whether the BIOS image upgrade is completed, and only when the upgrade is completed, the BIOS image file is actually updated. In case of upgrade failure, the BMC can easily restore the previous BIOS image.
