Description

Technical Field

[0001] This invention belongs to the field of server firmware management technology, specifically relating to a unified server firmware management system, method, apparatus, device, and medium. Background Technology

[0002] BIOS is short for Basic Input Output System.

[0003] SCP is short for System Control Processor.

[0004] BMC is short for Baseboard Management Controller.

[0005] CPLD is short for Complex Programmable Logic Device.

[0006] To meet the increasingly demanding performance and functional requirements of server systems, improving boot speed and startup stability has become a continuous pursuit in server development. Currently, to improve BIOS firmware update speed, the BIOS firmware required for system boot is split into a BIOS part and an SCP part. Less frequently updated content is placed in the SCP part, while the BIOS part stores frequently changing content. This approach ensures that the more stable SCP part does not change frequently, and when the BIOS firmware is updated, the fewer changes significantly increase the update speed. Furthermore, the SCP part can also act as a bridge for the BMC to access the CPU, providing an interface for the BMC to obtain some information from the CPU. Therefore, the method of splitting the original BIOS firmware into a BIOS part and an SCP part has become widely adopted.

[0007] However, with the BIOS firmware splitting method, the SCP part needs to work in conjunction with the BIOS part during server startup for the server to boot normally. But in reality, the two parts of the dual firmware are often incompatible and both require upgrades. Related technologies cover primary and backup BIOS upgrades, switching, and booting, but do not address dual firmware compatibility-level upgrades.

[0008] Therefore, in order to address the aforementioned shortcomings, it is essential to provide a unified firmware management system, method, apparatus, device, and medium for servers. Summary of the Invention

[0009] To address the shortcomings of splitting BIOS firmware into two parts to improve firmware update speed, but lacking dual firmware matching and upgrade methods, this invention provides a unified server firmware management system, method, apparatus, device, and medium to solve the aforementioned technical problems.

[0010] In a first aspect, the present invention provides a unified firmware management system for servers, including a baseboard management controller, a complex programmable logic device, a main basic input / output system flash memory, a backup basic input / output system flash memory, a main system control processor flash memory, a backup system control processor flash memory, and a host central processing unit.

[0011] The baseboard management controller is connected to the main basic input / output system flash memory, the backup basic input / output system flash memory, the main system control processor flash memory, and the backup system control processor flash memory.

[0012] The complex programmable logic device is connected to the main basic input / output system flash memory, the backup basic input / output system flash memory, the main system control processor flash memory, and the backup system control processor flash memory.

[0013] The complex programmable logic device is also connected to the baseboard management controller and the host central processing unit;

[0014] The main basic input / output system (MBI) flash memory stores the main basic input / output system firmware image, and the backup basic input / output system (SBI) flash memory stores the backup basic input / output system firmware image.

[0015] The main system control processor flash memory stores the main system control processor firmware image, and the backup system control processor flash memory stores the backup system control processor firmware image.

[0016] The complex programmable logic device selects the matching basic input / output system firmware image and system control processor firmware image to start based on the power-on status of the host central processing unit, and records the currently started primary and backup firmware images.

[0017] The baseboard management controller controls the upgrade of the basic input / output system firmware image and the system control processor firmware image, records the firmware image version in the flash memory, and updates the corresponding firmware image according to the currently booted primary and backup firmware images after the host central processing unit completes the boot process.

[0018] Furthermore, the baseboard management controller is also connected to a storage unit and a remote server;

[0019] The storage unit is used by the baseboard management controller to record the firmware image versions and the active status of each firmware image in the main basic input / output system flash memory, the backup basic input / output system flash memory, the main system control processor flash memory, and the backup system control processor flash memory.

[0020] The baseboard management controller connects to a remote server via an external interface, providing the server with firmware image version information for the primary BIOS flash memory, backup BIOS flash memory, primary system controller flash memory, and backup system controller flash memory. The baseboard management controller stores the BIOS firmware image versions in the primary and backup BIOS flash memories, as well as the system controller firmware image versions in the primary and backup system controller flash memories, through storage units. These storage units can use EEPROM, SD cards, or eMMC storage media. External interfaces include a web interface, an IPMI interface, and a Redfish interface.

[0021] Secondly, the present invention provides a unified firmware management method for servers, comprising the following steps:

[0022] S1. Select the matching basic input / output system firmware image and system control processor firmware image for startup based on the power-on status of the host central processing unit, and record the currently started primary and backup firmware images.

[0023] S2. Control the upgrade of the firmware image corresponding to the basic input / output system and system control processor, record the firmware image version after the upgrade, and update the corresponding firmware image according to the currently started primary and backup firmware images after the host central processing unit completes the startup.

[0024] Furthermore, the specific steps of step S1 are as follows:

[0025] S11. Configure the primary basic input / output system flash memory and the backup basic input / output system flash memory in advance for the basic input / output system firmware, and store the basic input / output system firmware image in the two basic input / output system flash memory;

[0026] S12. Configure the main system control processor flash memory and the backup system control processor flash memory in advance for the system control processor firmware, and store the system control processor firmware image in the two system control processor flash memories;

[0027] S13. The complex programmable logic device selects either the firmware image in the main basic input / output system flash memory and the main system control processor flash memory to boot, or selects the firmware image in the backup basic input / output system flash memory and the backup system control processor flash memory to boot, depending on the power-on status of the host central processing unit.

[0028] S14. Complex programmable logic device records the basic input / output system and system control processor main and backup firmware images used by the host central processing unit during startup.

[0029] Furthermore, the specific steps of step S13 are as follows:

[0030] S131. Complex programmable logic device determines whether the host central processing unit is starting up for the first time after power-on;

[0031] If so, proceed to step S133;

[0032] If not, proceed to step S132;

[0033] S132. The complex programmable logic device uses the basic input / output system firmware image in the flash memory of the basic input / output system used during the last normal startup, and the system control processor firmware image in the flash memory of the system control processor to start the host central processing unit, and proceeds to step S2.

[0034] S133. The complex programmable logic device selects the basic input / output system firmware image in the main basic input / output system flash memory and selects the system control processor firmware image in the main system control processor flash memory to match and start the host central processing unit.

[0035] S134. Complex programmable logic devices determine whether the host central processing unit has successfully started up;

[0036] If so, proceed to step S14;

[0037] If not, proceed to step S135;

[0038] S135. The complex programmable logic device selects a basic input / output system firmware image in the backup basic input / output system flash memory for the host central processing unit, and selects a system control processor firmware image in the backup system control processor flash memory for matching and booting.

[0039] Furthermore, the specific steps of step S14 are as follows:

[0040] S141. The complex programmable logic device has a first flag bit, a second flag bit, a third flag bit, and a fourth flag bit pre-configured;

[0041] S142. The complex programmable logic device uses the first flag bit to record the basic input / output system flash memory used by the host central processing unit (CPU) during startup, and uses the fourth flag bit to record the system control processor flash memory used by the CPU during startup.

[0042] S143. Complex programmable logic devices determine whether there is a startup failure during the startup process of the host central processing unit by power-on timing, and when a startup failure occurs, determine whether the startup failure is the basic input / output system firmware image or the system control processor firmware image.

[0043] S144. The complex programmable logic device (CPLD) uses a combination of a second flag bit and a third flag bit to record whether the host CPU booted normally and the firmware image that failed to boot. The CPLD records whether the firmware image used for booting is in the main BIOS flash memory, the main system controller flash memory, or the backup BIOS flash memory or the backup system controller flash memory. Furthermore, in the event of a boot failure, it records whether the firmware image that failed to boot is in the main BIOS flash memory or the main system controller flash memory.

[0044] Furthermore, the specific steps of step S2 are as follows:

[0045] S21. The baseboard management controller controls the independent upgrade of the firmware images of the main basic input / output system flash memory, the backup basic input / output system flash memory, and the system control processor firmware images of the main system control processor flash memory and the backup system control processor flash memory, and records the firmware image version in each flash memory after the upgrade and the active status of each firmware image.

[0046] S22. After the host CPU successfully boots up, the baseboard management controller queries the complex programmable logic device for the main and backup firmware images used by the host CPU for booting up and the power-on boot information.

[0047] S23. The baseboard management controller determines whether the host central processing unit failed to boot from the firmware image in the main basic input / output system flash memory or the main system control processor flash memory during the last power-on.

[0048] If so, proceed to step S24;

[0049] If not, proceed to step S25;

[0050] S24. The baseboard management controller logs the firmware image that failed to boot and reminds the user to update the firmware image, then returns to step S13.

[0051] S25. The baseboard management controller determines whether the firmware image version in the main basic input / output system flash memory is higher than that in the backup basic input / output system flash memory, and whether the firmware image version in the main system control processor flash memory is higher than that in the backup system control processor flash memory. If the firmware image versions in the main basic input / output system flash memory and the main system control processor flash memory are higher, the controller updates the firmware image versions in the backup basic input / output system flash memory and the backup system control processor flash memory. The baseboard management controller stores the firmware image versions in the main basic input / output system flash memory, the backup basic input / output system flash memory, the main system control processor flash memory, and the backup system control processor flash memory through storage units. The storage units can use EEPROM, SD cards, and eMMC storage media. The active state of the firmware image refers to the usage state of the firmware image in the flash memory during the central processing unit's boot process.

[0052] Furthermore, the specific steps of step S22 are as follows:

[0053] S221. After the host central processing unit is successfully powered on, the baseboard management controller actively polls the four flag bits of the complex programmable logic device;

[0054] S222. The baseboard management controller determines, based on the first flag bit, whether the host central processing unit boots from the main basic input / output system flash memory or the firmware image in the backup basic input / output system flash memory;

[0055] S223. The baseboard management controller determines, based on the fourth flag bit, whether the host central processing unit starts up with the main system control processor flash memory or the firmware image in the backup system control processor flash memory;

[0056] S224. The baseboard management controller determines whether the host central processing unit is booting normally based on the combination of the second and third flag bits. If it is not booting normally, the problem is either with the main basic input / output system flash memory or with the firmware image in the main system control processor flash memory.

[0057] Furthermore, the specific steps of step S25 are as follows:

[0058] S251. The baseboard management controller determines whether the main basic input / output system flash memory is higher than the basic input / output system firmware image version in the backup basic input / output system flash memory;

[0059] If so, proceed to step S252;

[0060] If not, proceed to step S254;

[0061] S252. The baseboard management controller determines that the basic input / output system firmware image in the main basic input / output system flash memory was upgraded before the host central processing unit was powered on;

[0062] S253. The baseboard management controller updates the basic input / output system firmware image in the backup basic input / output system flash memory to the same version as that in the main basic input / output system flash memory;

[0063] S254. The baseboard management controller determines whether the flash memory of the main system control processor is higher than the firmware image version of the system control processor in the flash memory of the backup system control processor;

[0064] If so, proceed to step S255;

[0065] If not, return to step S13;

[0066] S255. The baseboard management controller determines that the system control processor firmware image in the main system control processor flash memory was upgraded before the host central processing unit was powered on;

[0067] S256. The baseboard management controller updates the system control processor firmware image in the backup system control processor flash memory to the same version as that in the main system control processor flash memory, and returns to step S13. When the firmware image in the main flash memory has been upgraded, the version in the main flash memory will be higher than that in the backup flash memory. Updating the backup flash memory ensures that the backup flash memory contains the latest bootable image version, so that if the image in the main flash memory fails to boot next time, it can sequentially switch to the newer version of the backup image.

[0068] Thirdly, the present invention provides a unified firmware management device for servers, comprising:

[0069] The host central processing unit boot control module is used to select the matching basic input / output system firmware image and system control processor firmware image for booting according to the power-on status of the host central processing unit, and to record the currently booted primary and backup firmware images.

[0070] The firmware image upgrade module is used to control the upgrade of the firmware image corresponding to the basic input / output system and the system control processor, record the firmware image version after the upgrade, and update the corresponding firmware image according to the currently booted primary and backup firmware images after the host central processing unit has completed the boot process.

[0071] Furthermore, the host central processing unit boot control module includes a basic input / output system main and backup flash memory configuration unit, a system control processor main and backup flash memory configuration unit, and complex programmable logic devices;

[0072] The complex programmable logic device includes a boot firmware image selection unit and a boot firmware image recording unit;

[0073] The Elementary Input / Output System (API) primary and backup flash memory configuration unit is used to pre-configure the primary API flash memory and backup API flash memory for the API firmware, and to store the API firmware image in the two API flash memory.

[0074] The system control processor primary and backup flash memory configuration unit is used to pre-configure the primary system control processor flash memory and backup system control processor flash memory for the system control processor firmware, and to store the system control processor firmware image in the two system control processor flash memories;

[0075] The firmware image selection unit is used to select the firmware image in the main basic input / output system flash memory and the main system control processor flash memory for booting, or select the firmware image in the backup basic input / output system flash memory and the backup system control processor flash memory for booting, depending on the power-on status of the host central processing unit.

[0076] The firmware image recording unit is used to record the basic input / output system and system control processor primary and backup firmware images used by the host central processing unit during startup.

[0077] Furthermore, the firmware image upgrade module includes:

[0078] The upgrade control recording unit is used to control the independent upgrade of the firmware images of the main basic input / output system flash memory, the backup basic input / output system flash memory, and the system control processor firmware images of the main system control processor flash memory and the backup system control processor flash memory, and to record the firmware image version in each flash memory after the upgrade and the active status of each firmware image.

[0079] The firmware image query unit is used to query the firmware image used by the host CPU for booting and power-on information after the host CPU has successfully booted.

[0080] The main firmware uses a judgment unit to determine whether the host central processing unit failed to boot from the firmware image in the main basic input / output system flash memory or the main system control processor flash memory during the last power-on.

[0081] The firmware image boot failure recording unit is used to log the firmware image that failed to boot when there is a firmware image in the main basic input / output system flash memory or the main system control processor flash memory. It also reminds users to update the firmware image.

[0082] The backup firmware image update unit is used to determine whether the firmware image version in the main BIOS flash memory is higher than that in the backup BIOS flash memory, and whether the firmware image version in the main system control processor flash memory is higher than that in the backup system control processor flash memory. If the firmware image versions in the main BIOS flash memory and the main system control processor flash memory are higher, the unit updates the firmware image versions in both. The firmware image upgrade module is located in the baseboard management controller.

[0083] Fourthly, the present invention provides a device,

[0084] Including processor and memory;

[0085] The memory is used to store a computer program, and the processor is used to retrieve and run the computer program from the memory, causing the device to perform the method described in the second aspect above.

[0086] Fifthly, the present invention provides a storage medium,

[0087] The storage medium stores instructions that, when run on a computer, cause the computer to perform the method described in the second aspect above.

[0130] S13. The CPLD selects either the firmware image in the main BIOS flash memory and the main SCP flash memory for booting or the firmware image in the backup BIOS flash memory and the backup SCP flash memory for booting, depending on the power-on status of the host CPU.

[0131] S14.CPLD records the BIOS and SCP primary and backup firmware images used by the host CPU during startup;

[0132] S2. Control the upgrade of the firmware image corresponding to the BIOS and SCP, record the firmware image version after the upgrade, and update the corresponding firmware image according to the currently booting primary and backup firmware images after the host CPU completes the boot process; the specific steps of step S2 are as follows:

[0133] S21.BMC controls the independent upgrade of the BIOS firmware image in the main BIOS flash memory and the backup BIOS flash memory, as well as the SCP firmware image in the main SCP flash memory and the backup SCP flash memory, and records the firmware image version in each flash memory after the upgrade and the active status of each firmware image.

[0134] S22. After the host CPU successfully boots up, the BMC queries the CPLD for the primary and backup firmware images used by the host CPU for booting up and the power-on boot information;

[0135] S23.BMC determines whether the host CPU failed to boot from the firmware image in the main BIOS flash memory or main SCP flash memory during the last power-on;

[0136] If so, proceed to step S24;

[0137] If not, proceed to step S25;

[0139] S25. The BMC determines whether the firmware image version in the primary BIOS flash memory is higher than that in the backup BIOS flash memory, and whether the firmware image version in the primary SCP flash memory is higher than that in the backup SCP flash memory. If the firmware image version in the primary BIOS flash memory and the primary SCP flash memory is higher, the BMC updates the firmware image versions in the backup BIOS flash memory and the backup SCP flash memory. The BMC stores the BIOS firmware image versions in the primary BIOS flash memory and the backup BIOS flash memory, as well as the SCP firmware image versions in the primary SCP flash memory and the backup SCP flash memory, through storage units; the storage units can use EEPROM, SD cards, and eMMC storage media. The active status of the firmware image refers to the usage status of the firmware image in the flash memory during CPU boot.

[0140] In some embodiments, such as Figure 4 As shown, the specific steps of step S13 are as follows:

[0141] S131. The CPLD determines whether the host CPU is starting up for the first time after power-on;

[0142] If so, proceed to step S133;

[0143] If not, proceed to step S132;

[0144] S132.CPLD uses the BIOS firmware image in the BIOS flash memory used during the last normal boot and the SCP firmware image in the SCP flash memory to boot the host CPU and proceed to step S2.

[0145] S133.CPLD selects the BIOS firmware image in the main BIOS flash memory and selects the SCP firmware image in the main SCP flash memory to match and boot the host CPU;

[0146] S134. The CPLD determines whether the host CPU has successfully booted up;

[0147] If so, proceed to step S14;

[0148] If not, proceed to step S135;

[0149] S135.CPLD selects the BIOS firmware image in the backup BIOS flash memory and the SCP firmware image in the backup SCP flash memory for the host CPU to match and boot.

[0150] In some embodiments, step S14 specifically includes the following steps:

[0151] S141. The CPLD pre-sets the first flag bit, the second flag bit, the third flag bit, and the fourth flag bit;

[0152] S142.CPLD uses the first flag bit to record the BIOS flash memory used by the host CPU for booting, and the fourth flag bit to record the SCP flash memory used by the host CPU for booting.

[0153] S143.CPLD determines whether there is a boot failure during the host CPU boot process by checking the power-on timing sequence, and when a boot failure occurs, it determines whether the failure is due to the BIOS firmware image or the SCP firmware image.

[0154] The S144.CPLD uses a combination of the second and third flag bits to record whether the host CPU boots normally and the firmware image that failed to boot. The CPLD records whether the firmware image used for booting is from the main BIOS flash memory, the main SCP flash memory, or the backup BIOS flash memory or the backup SCP flash memory. In the event of a boot failure, it records whether the firmware image that failed to boot is from the main BIOS flash memory or the main SCP flash memory.

[0155] In some embodiments, step S22 specifically includes the following steps:

[0156] S221. After the host CPU successfully boots up, the BMC actively polls the four flag bits of the CPLD;

[0157] S222.BMC determines whether the host CPU boots from the main BIOS flash memory or the firmware image in the backup BIOS flash memory based on the first flag bit.

[0158] S223.BMC determines whether the host CPU boots from the main SCP flash memory or the firmware image in the backup SCP flash memory based on the fourth flag bit.

[0160] In some embodiments, step S25 specifically includes the following steps:

[0161] S251.BMC determines whether the main BIOS flash memory version is higher than the BIOS firmware image version in the backup BIOS flash memory;

[0162] If so, proceed to step S252;

[0163] If not, proceed to step S254;

[0164] S252.BMC determined that the BIOS firmware image in the main BIOS flash memory had been upgraded before the host CPU booted up;

[0165] S253.BMC updates the BIOS firmware image in the backup BIOS flash memory to the same version as that in the main BIOS flash memory;

[0166] S254.BMC determines whether the primary SCP flash memory version is higher than the SCP firmware image version in the backup SCP flash memory;
