Description

Technical Field

[0001] This application relates to the field of computer technologies, and particularly to a firmware upgrade method, apparatus, device, storage medium, and program product. Background Art

[0002] With the rapid development of computer technologies, the software and firmware of electronic products also need to be continuously upgraded. For example, the CPLD (Complex Programmable Logic Device) firmware of the CPLD chip deployed in a server is upgraded.

[0003] In the prior art, the BMC (Baseboard Management Controller) deployed in a server can be used to perform an online upgrade of the CPLD firmware. However, since the CPLD firmware controls and manages the power supply of the entire server, when the CPLD firmware is upgraded, the CPLD cannot normally provide stable power management services for the server, resulting in the shutdown of the server and making the server unable to operate normally.

[0004] Therefore, the above firmware upgrade method has the problem of poor service reliability of the CPLD. Summary of the Invention

[0005] Based on this, it is necessary to provide a firmware upgrade method, apparatus, device, storage medium, and program product that can improve the service reliability of the CPLD during the firmware upgrade process of the CPLD for the above technical problems.

[0006] In a first aspect, this application provides a firmware upgrade method for a Baseboard Management Controller (BMC), and the method includes:

[0007] Controlling a Complex Programmable Logic Device (CPLD) to copy a first firmware before upgrade to a target storage space, and after the copying of the first firmware is completed, writing a second firmware for firmware upgrade into the firmware storage space of the CPLD;

[0008] If the firmware activation condition is not satisfied, controlling the CPLD to operate based on the first firmware in the target storage space;

[0009] If the firmware activation condition is satisfied, performing a firmware activation process on the second firmware to enable the CPLD to operate based on the second firmware.

[0010] In the above embodiments, during the process of firmware upgrade and activation of the CPLD, the CPLD can simultaneously run the first firmware before upgrade that has been previously copied to the target storage space, and will only execute the firmware activation process for the second firmware when the firmware activation condition is met, so as to avoid the problem that the server cannot operate normally due to the inability to provide stable power management services to the server during the upgrade and activation process of the CPLD firmware, and improve the service reliability of the CPLD.

[0011] In one of the embodiments, controlling the CPLD to copy the first firmware before upgrade to the target storage space includes:

[0012] Determine whether the current upgrade condition configured in the BMC is met;

[0013] If the upgrade condition is met, execute the step of controlling the CPLD to copy the first firmware before upgrade to the target storage space.

[0014] In the above embodiments, the BMC needs to determine whether the current upgrade condition is met before upgrading the first firmware stored in the firmware storage space of the CPLD.

[0016] Determine whether the uploaded second firmware is received and whether a firmware upgrade instruction is received;

[0023] In one embodiment, determining whether the firmware activation condition is satisfied according to the power state includes:

[0024] If the power state is the shutdown state, it is determined that the firmware activation condition is satisfied.

[0025] In the above embodiment, the BMC determines that the firmware activation condition is satisfied only when the power state is shutdown, and then executes the subsequent firmware activation process, avoiding the server from shutting down or restarting suddenly due to the execution of the firmware activation process, thus interrupting the business that may be in progress, and improving the service reliability of the server.

[0026] In one embodiment, the method further includes:

[0032] If the firmware activation condition is not satisfied, work is performed based on the first firmware in the target storage space according to the control of the BMC;

[0033] If the firmware activation condition is satisfied, after the BMC executes the firmware activation process for the second firmware, work is performed based on the second firmware.

[0037] An activation module, configured to perform a firmware activation process on a second firmware if a firmware activation condition is satisfied, so that the CPLD operates based on the second firmware.

[0038] In a fourth aspect, the present application further provides a firmware upgrade device for a CPLD. The device includes:

[0039] A copy and write module, configured to copy a first firmware before upgrade to a target storage space according to the control of the BMC, and after the copying of the first firmware is completed, write a second firmware for firmware upgrade into the firmware storage space;

[0040] A first firmware operation module, configured to operate based on the first firmware in the target storage space according to the control of the BMC if the firmware activation condition is not satisfied;

[0041] A second firmware operation module, configured to operate based on the second firmware after the BMC performs a firmware activation process on the second firmware if the firmware activation condition is satisfied.

[0043] In a sixth aspect, an embodiment of the present application provides a computer-readable storage medium, on which a computer program is stored.

[0045] The above firmware upgrade method, device, equipment, storage medium, and program product control a Complex Programmable Logic Device (CPLD) to copy the first firmware before upgrade to a target storage space. After the copying of the first firmware is completed, the second firmware for firmware upgrade is written into the firmware storage space of the CPLD. Then, if the firmware activation condition is not met, the CPLD is controlled to work based on the first firmware in the target storage space. If the firmware activation condition is met, a firmware activation process is executed for the second firmware so that the CPLD works based on the second firmware. In this way, during the firmware upgrade and activation process of the CPLD, the CPLD can simultaneously run the first firmware before upgrade that was previously copied to the target storage space, and the firmware activation process for the second firmware is only executed when the firmware activation condition is met, to avoid the problem that the server cannot operate normally due to the inability to provide stable power management services to the server during the firmware upgrade and activation process of the CPLD, and improve the service reliability of the CPLD.

[0056] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0057] With the rapid development of computer technology, the software and firmware of electronic products also need to be continuously upgraded. For example, the CPLD firmware of the CPLD chip (Complex Programmable Logic Device) deployed in the server needs to be upgraded.

[0058] In the prior art, the BMC (Baseboard Management Controller) deployed in the server can be used to perform online upgrade of the CPLD firmware. However, since the CPLD firmware controls and manages the power supply of the entire server, when the CPLD firmware is upgraded, the CPLD cannot normally provide stable power management services for the server, and the power supply system will be initialized, resulting in the shutdown of the server and the server cannot run normally.

[0059] Therefore, the above firmware upgrade method has the problem of poor service reliability of the CPLD.

[0060] In view of this, the embodiments of the present application provide a firmware upgrade method, device, equipment, storage medium and program product. By controlling the complex programmable logic device CPLD to copy the first firmware before upgrade to the target storage space, and after the first firmware is copied, writing the second firmware for firmware upgrade into the firmware storage space of the CPLD. Then, if the firmware activation condition is not met, control the CPLD to work based on the first firmware in the target storage space. If the firmware activation condition is met, perform the firmware activation process for the second firmware, so that the CPLD works based on the second firmware. In this way, during the firmware upgrade and activation process of the CPLD, the CPLD can simultaneously run the first firmware before upgrade that is copied to the target storage space in advance, and will only execute the firmware activation process for the second firmware when the firmware activation condition is met, so as to avoid the problem that the server cannot run normally due to the inability to provide stable power management services to the server during the upgrade and activation process of the CPLD firmware, and improve the service reliability of the CPLD.

[0061] The firmware upgrade method provided by the embodiments of this application can be applied to, for example, Figure 1 the application environment shown. Among them, CPLD102 is connected to BMC104 through a hardware interface.

[0062] In an exemplary embodiment, as Figure 2 shown, a firmware upgrade method is provided. Taking the BMC104 in Figure 1 as an example, the method includes the following steps:

[0063] Step 201, control the Complex Programmable Logic Device (CPLD) to copy the first firmware before upgrade to the target storage space, and after the first firmware is copied, write the second firmware for firmware upgrade into the firmware storage space of the CPLD.

[0064] When the BMC upgrades the firmware of the CPLD, the first firmware before the CPLD upgrade will be upgraded to the second firmware. Therefore, before the BMC upgrades the firmware of the CPLD, the second firmware for firmware upgrade will be obtained. Regarding the method for obtaining the second firmware, optionally, the BMC obtains the second firmware uploaded by the user through other devices; optionally, the BMC sends a request to the remote server to receive the second firmware sent by the remote service. The method for the BMC to obtain the second firmware is not specifically limited herein.

[0065] The firmware of the CPLD (i.e., the first firmware) is usually stored in the firmware storage space, and this firmware storage space usually exists in a non-volatile memory. When upgrading the first firmware of the CPLD, usually the second firmware for firmware upgrade is written into this firmware storage space to replace the first firmware, but this will affect the operation of the first firmware before upgrade in the original storage space. Therefore, in the embodiments of this application, before the BMC upgrades the first firmware of the CPLD, it will control the CPLD to copy the first firmware before upgrade to the target storage space. The target storage space is a storage space that does not belong to the non-volatile memory, and when the content in the target storage space is running, the content in the target storage space cannot be modified. For example, the target storage space belongs to the memory of the CPLD.

[0066] Regarding the method for the BMC to obtain the first firmware and control the CPLD to copy the first firmware to the target storage space, optionally, the BMC controls the CPLD to copy the first firmware originally stored in the firmware storage space to the target storage space; optionally, the BMC obtains the first firmware from other devices, and then controls the CPLD to copy the first firmware to the target storage space.

[0067] After the BMC controls the CPLD to copy the first firmware to the target storage space, when writing the second firmware to the firmware storage space, it can simultaneously control the CPLD to run the first firmware in the target storage space, so that the power management service provided to the server is not affected.

[0068] The method for the BMC to write the second firmware to the firmware storage space is as follows: First, the BMC generates an erase instruction, which is used to instruct the CPLD to erase the first firmware stored in the firmware storage space; then, the BMC generates a write instruction, which is used to instruct the CPLD to write the second firmware to the firmware storage space; then, the BMC generates a verification instruction to verify the content stored in the firmware storage space of the CPLD to determine whether the second firmware is correctly written to the firmware storage space of the CPLD.

[0069] The following describes the process of the BMC verifying the content stored in the firmware storage space of the CPLD.

[0070] Optionally, the BMC compares the content read from the firmware storage space of the CPLD with the second firmware line by line, and the comparison result can be used to indicate whether the second firmware is correctly written to the firmware storage space; optionally, the BMC generates a first verification code corresponding to the second firmware according to a preset verification condition, and then generates a second verification code corresponding to the content read from the firmware storage space of the CPLD according to the same preset verification condition, and compares the first verification code with the second verification code, and the comparison result can be used to indicate whether the second firmware is correctly written to the firmware storage space.

[0071] Step 202, if the firmware activation condition is not met, control the CPLD to work based on the first firmware in the target storage space.

[0072] After the BMC controls the CPLD to successfully write the second firmware to the firmware storage space of the CPLD, it is also necessary to perform an activation process on the second firmware in the firmware storage space of the CPLD before the CPLD can work based on the second firmware.

[0073] In a possible implementation, the BMC needs to determine whether the current environment meets the firmware activation condition, so as to determine whether the activation process can be performed on the second firmware.

[0074] Regarding the method for the BMC to obtain the firmware activation condition, optionally, the firmware activation condition is stored in the BMC, and the BMC can directly obtain the firmware activation condition; optionally, the firmware activation condition is stored in the CPLD, and the BMC sends a request to the CPLD to obtain the firmware activation condition feedback by the CPLD. The method for the BMC to obtain the firmware activation condition is not specifically limited here.

[0075] After the BMC controls the CPLD to correctly write the second firmware into the firmware storage space, it will determine whether the current operating environment meets the firmware activation conditions. In the embodiment of the present application, if the BMC determines that the current operating environment does not meet the firmware activation conditions, it will continue to control the CPLD to run the first firmware in the target storage space to avoid the CPLD incorrectly running the unactivated second firmware that has been written into the firmware storage space, so that the stable power management service provided to the server is not affected.

[0076] When the BMC determines that the current operating environment does not meet the firmware activation conditions, while continuing to control the CPLD to run the first firmware in the target storage space, it will also monitor the status of the operating environment in real time until the BMC detects that the current operating environment meets the firmware activation conditions, and then it will execute the activation process for the second firmware.

[0077] In a possible implementation manner, the BMC determines the current operating environment. If it does not meet the firmware activation conditions, it will set a waiting activation flag. In the presence of the flag, it will periodically detect whether the firmware activation conditions are met. When the BMC detects that the current operating environment meets the firmware activation conditions, after executing the firmware activation process for the second firmware, it will eliminate the waiting activation flag. In this way, when the BMC executes the firmware activation process for the second firmware and still detects the waiting activation flag, it can be determined that the firmware activation process fails. The BMC monitors in real time whether the current conditions for firmware activation are met, and then, when the conditions for firmware activation are met, it will execute the firmware activation process for the second firmware again.

[0078] Step 203, if the firmware activation conditions are met, then execute the firmware activation process for the second firmware so that the CPLD works based on the second firmware.

[0079] In a possible implementation manner, after the BMC controls the CPLD to correctly write the second firmware into the firmware storage space, if it determines that the current operating environment meets the firmware activation conditions, it will directly execute the firmware activation process for the second firmware so that the CPLD works based on the second firmware; in another possible implementation manner, after the BMC controls the CPLD to correctly write the second firmware into the firmware storage space, if it determines that the current operating environment does not meet the firmware activation conditions, it will monitor the status of the operating environment in real time until the BMC detects that the current operating environment meets the firmware activation conditions, and then it will execute the activation process for the second firmware.

[0080] The above firmware upgrade method copies the first firmware before upgrade to the target storage space by controlling a complex programmable logic device (CPLD). After the copying of the first firmware is completed, the second firmware for firmware upgrade is written into the firmware storage space of the CPLD. Then, if the firmware activation condition is not met, the CPLD is controlled to work based on the first firmware in the target storage space. If the firmware activation condition is met, the firmware activation process is executed for the second firmware so that the CPLD works based on the second firmware. In this way, during the firmware upgrade and activation process of the CPLD, the CPLD can simultaneously run the first firmware before upgrade that has been copied to the target storage space in advance, and the firmware activation process for the second firmware will only be executed when the firmware activation condition is met, so as to avoid the problem that the server cannot run normally due to the inability to provide stable power management services to the server during the firmware upgrade and activation process of the CPLD, and improve the service reliability of the CPLD.

[0081] In one embodiment, based on the above Figure 2 illustrated embodiment, refer to Figure 3 , this embodiment relates to the process of controlling the CPLD to copy the first firmware before upgrade to the target storage space. As Figure 3 shown, step 201 includes:

[0082] Step 301, determine whether the current upgrade condition configured in the BMC is met.

[0083] The upgrade condition is used for the BMC to determine whether the current operating environment can upgrade the first firmware stored in the firmware storage space of the CPLD according to the upgrade condition.

[0084] In a possible implementation, the BMC needs to determine whether the current operating environment meets the upgrade condition configured in the BMC. After the operating environment meets the upgrade condition configured in the BMC, the BMC can execute the subsequent firmware upgrade steps.

[0085] Regarding the method for the BMC to determine whether the current upgrade condition configured in the BMC is met, in a possible implementation, the BMC needs to determine whether the uploaded second firmware is received and whether the firmware upgrade instruction is received. If the second firmware and the firmware upgrade instruction are received, it is determined that the upgrade condition is met.

[0086] Among them, the firmware upgrade instruction is an instruction for the BMC to upgrade the first firmware in the firmware storage space of the CPLD according to the second firmware. Optionally, the BMC obtains the firmware upgrade instruction uploaded by the user through other devices; optionally, the BMC obtains the firmware upgrade instruction sent regularly in the system. The method for the BMC to obtain the CPLD firmware upgrade instruction is not specifically limited here.

[0087] Step 302, if the upgrade condition is met, execute the step of controlling the CPLD to copy the first firmware before upgrade to the target storage space.

[0088] When the BMC detects that the current upgrade condition is met, it can start to execute the step of controlling the CPLD to copy the first firmware before upgrade to the target storage space.

[0089] Thus, in the above embodiment, the BMC needs to determine whether the current upgrade condition is met before upgrading the first firmware stored in the firmware storage space of the CPLD. Only when the upgrade condition is met can the subsequent firmware upgrade steps be executed, improving the security of firmware upgrade.

[0090] In one embodiment, based on the above Figure 2 illustrated embodiment, refer to Figure 4 , this embodiment relates to the process of determining whether the current firmware activation condition is met. As Figure 4 illustrated, this process includes:

[0091] Step 401, obtain the power state of the server.

[0092] In a possible implementation manner, the firmware activation condition is that the server is in the shutdown state. Therefore, the BMC needs to obtain the power state of the server, and then determine whether the firmware activation condition is met according to the power state.

[0093] Step 402, determine whether the firmware activation condition is met according to the power state.

[0094] Optionally, if the power state is the shutdown state, it is determined that the firmware activation condition is met. At this time, the BMC executes the firmware activation process for the second firmware, enabling the CPLD to be initialized. After the power state of the server is turned on again, the second firmware becomes effective and the CPLD can work based on the second firmware. Optionally, if the power state is the normal running state, the BMC determines that the current firmware activation condition is not met. At this time, the BMC monitors the power state of the server in real time until the power state meets the firmware activation condition, and then executes the firmware activation process.

[0095] Thus, in the above embodiment, the BMC determines whether the current power state of the server meets the firmware activation condition before executing the firmware activation process for the second firmware. Only when the firmware activation condition is met will the firmware activation process be executed, avoiding the server being suddenly shut down due to the execution of the firmware activation process, thereby interrupting the possibly ongoing business and improving the service reliability of the server.

[0096] In one embodiment, as Figure 5 illustrated, a firmware upgrade method is provided. This method is applied to Figure 1Taking CPLD102 in [the relevant context] as an example for illustration, it includes the following steps:

[0097] Step 501, according to the control of the BMC, copy the first firmware before upgrade to the target storage space, and after the copying of the first firmware is completed, write the second firmware for firmware upgrade into the firmware storage space.

[0098] In a possible implementation manner, when the CPLD performs firmware upgrade, it will copy the first firmware to the target storage space according to the control of the BMC. For the method by which the BMC obtains the first firmware and controls the CPLD to copy the first firmware to the target storage space, reference can be made to the relevant descriptions in the above embodiments, which will not be elaborated here.

[0099] After the CPLD copies the first firmware to the target storage space, it will write the second firmware into the firmware storage space of the CPLD according to the control of the BMC. The firmware storage space usually exists in the non-volatile memory. For the method by which the CPLD writes the second firmware into the firmware storage space based on the control of the BMC, reference can be made to the relevant descriptions in the above embodiments, which will not be elaborated here.

[0100] Step 502, if the firmware activation condition is not met, work based on the first firmware in the target storage space according to the control of the BMC.

[0101] In the embodiments of the present application, it is necessary for the BMC to judge whether the current environment meets the firmware activation condition. For the method by which the BMC specifically obtains the firmware activation condition and the method of judging whether the firmware activation condition is met, reference can be made to the relevant descriptions in the above embodiments, which will not be elaborated here.

[0102] When the BMC judges that the current environment does not meet the firmware activation condition, the CPLD will work based on the first firmware in the target storage space according to the control of the BMC, that is, at this time, the CPLD runs the first firmware in the target storage space according to the control of the BMC to provide stable power management services to the server.

[0103] Step 503, if the firmware activation condition is met, after the BMC executes the firmware activation process for the second firmware, work based on the second firmware.

[0104] When the BMC judges that the current environment meets the firmware activation condition, the BMC will execute the firmware activation process for the second firmware. For the process by which the BMC executes the activation process for the second firmware, reference can be made to the relevant descriptions in the above embodiments, which will not be elaborated here.

[0105] After the second firmware is activated, the CPLD can run the second firmware in the firmware storage space to perform work, and the firmware activation is completed.

[0106] In the above embodiments, the CPLD copies the first firmware before the upgrade to the target storage space in advance based on the control of the BMC, so that the CPLD can work based on the first firmware in the target storage space according to the control of the BMC during the subsequent firmware upgrade and activation process, and will only work based on the second firmware after the second firmware is activated, so as to avoid the problem that the server cannot operate normally caused by the inability to provide stable power management services to the server due to the need to write the second firmware to the firmware storage space during the firmware upgrade and activation process, and improve the service reliability of the CPLD.

[0107] In one embodiment, please refer to Figure 6 , which shows a flowchart of an exemplary firmware upgrade method provided by an embodiment of the present application. The method includes:

[0108] Step 601, the BMC determines whether the uploaded second firmware is received and whether a firmware upgrade instruction is received.

[0109] Step 602, if the BMC receives the second firmware and the firmware upgrade instruction, it determines that the upgrade condition is met.

[0110] Step 603, if the upgrade condition is met, the BMC executes the step of controlling the CPLD to copy the first firmware before the upgrade to the target storage space.

[0111] Step 604, the CPLD copies the first firmware before the upgrade to the target storage space according to the control of the BMC.

[0112] Step 605, after the first firmware is copied, the second firmware for firmware upgrade is written into the firmware storage space of the CPLD.

[0113] Step 606, after the first firmware is copied, the CPLD writes the second firmware for firmware upgrade into the firmware storage space.

[0114] Step 607, obtain the power status of the server.

[0115] Step 608, determine whether the firmware activation condition is met according to the power status.

[0116] Step 609, if the power status is the shutdown state, it is determined that the firmware activation condition is met.

[0117] Step 610, if the firmware activation condition is not met, control the CPLD to work based on the first firmware in the target storage space.

[0118] Step 611, if the firmware activation condition is not met, the CPLD works based on the first firmware in the target storage space according to the control of the BMC.

[0119] Step 612, if the firmware activation condition is not met, set a waiting-for-activation flag.

[0120] Step 613, when there is a flag, periodically detect whether the firmware activation condition is met.

[0121] Step 614, if the firmware activation condition is met, execute the firmware activation process for the second firmware so that the CPLD operates based on the second firmware.

[0122] Step 615, if the firmware activation condition is met, after the BMC executes the firmware activation process for the second firmware, the CPLD operates based on the second firmware.
