[0001] The present invention relates to the field of computer application technology, and in particular to a firmware refresh method, device, computer-readable storage medium and computer program product. Background Art

[0002] For system security and function expansion, the Basic Input / Output System (BIOS) firmware (Firmware, FW) needs to be upgraded. During the in-band BIOS upgrade process, the synchronous static random access memory (S3M SRAM) of the central processing unit (CPU) is already accessing the basic input / output system flash memory (BIOSFlash). When the CPU is unaware that the basic input / output system firmware in the flash memory has been upgraded, the firmware update will cause the server to be unable to boot normally. At this time, it is generally necessary to power off the system to recover, restart the server, and manually unplug the power cord, etc., which has high labor costs. In addition, restarting the server requires offline server-related services, affecting important business data of customers, data centers, etc.

[0003] In summary, how to effectively solve the current problem of needing to power off and restart the server to refresh the firmware, which has high labor costs and affects the normal business of the system, is an issue that technicians in this field urgently need to solve.

[0057] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0058] Referring to FIG. 1 , FIG. 1 is a flowchart of a firmware refresh method according to an embodiment of the present invention. The method may include the following steps:

[0059] S101: When it is detected that the basic input / output system firmware in the flash memory is upgraded, the current system advanced configuration and power interface status are obtained.

[0060] The system detects the upgrade status of the basic input and output system firmware in the flash memory, and when it detects that the upgrade of the basic input and output system firmware in the flash memory is completed, obtains the current system Advanced Configuration and Power Interface (ACPI) state. The system Advanced Configuration and Power Interface state can include the state where all devices are turned off (i.e., the S5 state) and the working state (i.e., the S0 state).

[0061] S102: When it is determined that the current system advanced configuration and power interface state is a device-all-off state, the auxiliary power signal and the device-all-off power reserve signal are controlled to be in a non-enabled state to clear the global reset state record.

[0062] After obtaining the current system advanced configuration and power interface status, when it is determined that the current system advanced configuration and power interface status is the device all shut down state, it means that the basic input and output system firmware in the synchronous static random access memory can be refreshed based on the new version of the basic input and output system firmware in the flash memory, and the auxiliary power signal (AUX_PWRGOOD) and the device all shut down power retention signal (S5_PWR_RETAINED) are controlled to be in a non-enabled state, thereby informing the central processor that the auxiliary power signal and the device all shut down power retention signal are in an unready state, and informing the synchronous static random access memory that the basic input and output system firmware needs to be refreshed from the flash memory, thereby clearing the global reset state record and avoiding the service being offline.

[0063] S103: When it is detected that the auxiliary power signal and the device all power off reserve signal are both in a disabled state, the upgraded basic input and output system firmware in the flash memory is refreshed to the synchronous static random access memory.

[0064] After controlling the auxiliary power signal and the device all power off reserve signal to be in a non-enabled state, it is detected whether the auxiliary power signal and the device all power off reserve signal are both in a non-enabled state. When it is detected that the auxiliary power signal and the device all power off reserve signal are both in a non-enabled state, it means that the power off and restart effect is achieved, but there is no need to actually manually unplug the power cord, and the basic input and output system firmware upgraded in the flash memory is refreshed to the synchronous static random access memory. In this way, the basic input and output system firmware can be upgraded without powering off, saving labor costs and avoiding the impact on the current running business of the system.

[0065] It can be seen from the above technical solution that when the upgrade of the basic input-output system firmware in the flash memory is detected to be completed, when it is determined that the current system advanced configuration and power interface state is the device all-off state, the auxiliary power signal and the device all-off power retention signal are controlled to be in a non-enabled state, thereby clearing the global reset state record, and then notifying the central processor that the auxiliary power signal and the device all-off power retention signal are in an unready state, and notifying the synchronous static random access memory that the basic input-output system firmware needs to be refreshed from the flash memory. The effect of power-off restart is achieved, but there is no need to actually manually unplug the power cord, so that the basic input-output system firmware can be upgraded without powering off, saving labor costs and avoiding the impact on the current running business of the system.

[0066] It should be noted that, based on the above embodiment, the embodiment of the present invention also provides corresponding improved solutions. In the subsequent embodiments, the same steps or corresponding steps as those in the above embodiment can be referenced to each other, and the corresponding beneficial effects can also be referenced to each other, which will not be repeated one by one in the following improved embodiments.

[0067] Referring to FIG. 2 , FIG. 2 is a flowchart of another firmware updating method according to an embodiment of the present invention. The method may include the following steps:

[0068] S201: When it is detected that the basic input / output system firmware in the flash memory is upgraded, the current system advanced configuration and power interface status are obtained.

[0069] The version information of the basic input-output system firmware in the flash memory can be detected at a preset time interval or in real time to obtain the first basic input-output system firmware version information, obtain the pre-stored second basic input-output system firmware version information, and determine whether the first basic input-output system firmware version information is consistent with the second basic input-output system firmware version information. If they are consistent, it means that the basic input-output system firmware in the flash memory has not been upgraded and no processing is required. If they are inconsistent, it means that the basic input-output system firmware in the flash memory has been upgraded. Next, when the conditions for upgrading the basic input-output system firmware in the synchronous static random access memory are met, the basic input-output system firmware in the synchronous static random access memory is upgraded. By detecting the upgrade status of the basic input-output system firmware in the flash memory according to the firmware version comparison method, accurate and rapid detection of the upgrade status of the basic input-output system firmware in the flash memory is achieved.

[0070] S202: When it is determined that the current system advanced configuration and power interface state is a device-all-off state, the auxiliary power signal and the device-all-off power reserve signal are controlled to be in a non-enabled state to clear the global reset state record.

[0071] S203: When it is detected that the auxiliary power signal and the device all power off reserve signal are both in a disabled state, the upgraded basic input and output system firmware in the flash memory is refreshed to the synchronous static random access memory.

[0072] S204: Control the auxiliary power signal and the device all power off retention signal to switch from the disabled state to the enabled state.

[0073] After the upgraded basic input-output system firmware in the flash memory is refreshed to the synchronous static random access memory, the auxiliary power signal and the device all power off reserve signal are controlled to be converted from the non-enabled state to the enabled state, thereby timely notifying the central processor that the auxiliary power signal and the device all power off reserve signal are in the ready state, and the basic input-output system firmware in the synchronous static random access memory has been refreshed.

[0074] S205: When it is detected that the current system advanced configuration and power interface state are converted from the all-device-off state to the working state, the control server runs based on the refreshed new version of the basic input / output system firmware.

[0075] After the upgraded basic input-output system firmware in the flash memory is refreshed to the synchronous static random access memory, when it is detected that the current system advanced configuration and power interface state are converted from the device all-off state to the working state, the server is controlled to run based on the refreshed new version of the basic input-output system firmware. Thus, the server runs based on the refreshed new version of the basic input-output system firmware, and the basic input-output system firmware is upgraded without powering off, which saves labor costs and improves the efficiency of firmware refresh.

[0076] In a specific implementation of the present invention, controlling the auxiliary power signal and the device all power off retention signal to be in a non-enabled state may include the following steps:

[0077] Control the auxiliary power signal and all equipment power off retention signal to be in low level state;

[0078] Accordingly, when it is detected that the auxiliary power signal and the device all power off reservation signal are both in a non-enabled state, refreshing the basic input and output system firmware upgraded in the flash memory to the synchronous static random access memory may include the following steps:

[0079] When it is detected that the auxiliary power signal and the device all power off reserve signal are both in a low level state, the basic input and output system firmware upgraded in the flash memory is refreshed to the synchronous static random access memory;

[0080] Accordingly, controlling the auxiliary power signal and the device all power off reservation signal to switch from a disabled state to an enabled state may include the following steps:

[0081] Controls the auxiliary power signal and the device all power off retention signal to transition from a low level state to a high level state.

[0082] When it is determined that the current system advanced configuration and power interface state is the device all-off state, it means that the basic input-output system firmware in the synchronous static random access memory can be refreshed based on the new version of the basic input-output system firmware in the flash memory, and the auxiliary power signal and the device all-off power retention signal are controlled to be in a low-level state, thereby notifying the central processing unit that the auxiliary power signal and the device all-off power retention signal are in an unready state, and notifying the synchronous static random access memory that the basic input-output system firmware needs to be refreshed from the flash memory. When it is detected that the auxiliary power signal and the device all-off power retention signal are both in a low-level state, it means that the effect of power-off restart has been achieved, but there is no need to actually manually unplug the power cord, and the basic input-output system firmware upgraded in the flash memory is refreshed to the synchronous static random access memory. After refreshing the basic input-output system firmware upgraded in the flash memory to the synchronous static random access memory, the auxiliary power signal and the device all-off power retention signal are controlled to be converted from a low-level state to a high-level state. Thus, the central processing unit is promptly notified that the auxiliary power signal and the device all-off power retention signal are both in a ready state, and the basic input-output system firmware in the synchronous static random access memory has been refreshed. The auxiliary power signal and the device all power off retention signal are generally in a high level state. By setting the low level state of the auxiliary power signal and the low level state of the device all power off retention signal as the trigger condition for refreshing the basic input and output system firmware in the synchronous static random access memory, the system can easily and accurately identify the timing of firmware refresh, thereby improving the accuracy of firmware refresh.

[0083] When the basic input and output system firmware in the flash memory is upgraded, an execution instruction for upgrading the basic input and output system firmware in the synchronous static random access memory can be sent to the baseboard management controller through the intelligent platform management interface (Intelligent Platform Management Interface, IPMI) command. After receiving the execution instruction, the baseboard management controller sends the instruction to the complex programmable logic device (Complex Programmable Logic Device, CPLD) through the serial interface bus (Inter-Integrated Circuit, I2C). After receiving the instruction, the complex programmable logic device recognizes that the system state is the device all shut down state, and controls the auxiliary power signal and the device all shut down power retention signal to be in a low level state.

[0084] In a specific embodiment of the present invention, controlling the auxiliary power signal and the device all power off reserve signal to switch from a low level state to a high level state may include the following steps:

[0085] Step 1: Count the duration that the auxiliary power signal and the device power-off retention signal are in a low-level state to obtain the statistical duration;

[0086] Step 2: When the statistical duration reaches the preset duration, the auxiliary power signal and the device all power off retention signal are controlled to switch from a low level state to a high level state.

[0087] For the convenience of description, the above two steps can be combined for explanation.

[0088] After the auxiliary power signal and the device power-off retention signal are controlled to be in a low-level state, the duration of the auxiliary power signal and the device power-off retention signal being in a low-level state is counted to obtain the statistical duration. When the statistical duration reaches the preset duration, the auxiliary power signal and the device power-off retention signal are controlled to switch from a low-level state to a high-level state. By automatically switching the auxiliary power signal and the device power-off retention signal from a low-level state to a high-level state according to the duration statistics, while ensuring that the firmware refresh is completed, the auxiliary power signal and the device power-off retention signal can be automatically and timely switched to the state before control, without the need for manual intervention, saving manpower and improving the user experience.

[0089] It should be noted that the preset duration can be set and adjusted according to actual conditions. For example, the preset duration can be set and adjusted according to the length of time from controlling the auxiliary power signal and the device to turn off all power to retain the signal in a low level state to completing the firmware refresh. The embodiments of the present invention are not limited to this.

[0090] In a specific implementation of the present invention, after obtaining the current system advanced configuration and power interface status, the method may further include the following steps:

[0091] When it is determined that the current system advanced configuration and power interface states are in a working state, the preset upgrade flag is converted from a non-enabled state to an enabled state.

[0092] After obtaining the current system advanced configuration and power interface status, when it is determined that the current system advanced configuration and power interface status is in the working state, it means that the basic input-output system firmware in the synchronous static random access memory cannot be refreshed based on the new version of the basic input-output system firmware in the flash memory, and the preset upgrade flag is converted from a non-enabled state to an enabled state. By pre-setting the upgrade flag to mark the basic input-output system firmware in the synchronous static random access memory as needing to be refreshed, an effective mark for firmware refresh is realized, so that when the system advanced configuration and power interface status is converted to the device fully shut down state, the firmware can be refreshed in time by identifying the upgrade flag.

[0093] In a specific implementation of the present invention, after converting the preset upgrade flag bit from a disabled state to an enabled state, the method may further include the following steps:

[0094] Step 1: Monitor the current system advanced configuration and power interface status;

[0095] Step 2: When it is detected that the current system advanced configuration and power interface status is converted from the working status to the device all shut down status, the step of controlling the auxiliary power signal and the device all shut down power reserve signal to be in a non-enabled state is executed.

[0096] For the convenience of description, the above two steps can be combined for explanation.

[0097] After the preset upgrade flag is converted from the non-enabled state to the enabled state, the current system advanced configuration and power interface state are monitored. When it is detected that the current system advanced configuration and power interface state are converted from the working state to the device fully shut down state, the auxiliary power signal and the device fully shut down power retention signal are controlled to the non-enabled state, thereby performing firmware refresh. By monitoring the current system advanced configuration and power interface state after the preset upgrade flag is converted from the non-enabled state to the enabled state, the firmware refresh timing is obtained in a timely manner, thereby improving the firmware refresh efficiency.

[0098] In a specific embodiment of the present invention, the method may further include the following steps:

[0099] Step 1: If the current system advanced configuration and power interface states are changed from the device all-off state to the working state during the firmware update to the synchronous static random access memory, the preset upgrade operation statistics flag is changed from the disabled state to the enabled state;

[0100] Step 2: Count the number of upgrade operations to obtain a counting result.

[0101] For the convenience of description, the above two steps can be combined for explanation.

[0102] If the current system advanced configuration and power interface status are changed from the device all-off state to the working state during the firmware refresh to the synchronous static random access memory, it means that the firmware refresh process is interrupted, and the pre-set upgrade operation statistics flag is changed from the non-enabled state to the enabled state, and the number of upgrade operations is counted to obtain the counting result. By setting the upgrade operation statistics flag to mark that the basic input and output system firmware has been refreshed, but the firmware refresh process was interrupted and not completed, the system and users can timely grasp the firmware refresh status according to the upgrade operation statistics flag. By counting the number of upgrade operations, users can timely understand the number of times the firmware refresh has not been completed, and take timely countermeasures according to the counting results.

[0103] In a specific implementation of the present invention, when it is determined that the current system advanced configuration and power interface state is a device-all-off state, controlling the auxiliary power signal and the device-all-off power reserve signal to be in a non-enabled state may include the following steps:

[0104] Step 1: When it is determined that the current system advanced configuration and power interface status is that all devices are turned off, obtain the upgrade operation statistics flag bit;

[0105] Step 2: When the upgrade operation statistics flag is enabled, obtain the counting result;

[0106] Step 3: Determine whether the counting result is greater than or equal to the preset value, if not, execute step 4, if yes, execute step 5;

[0107] Step 4: Control the auxiliary power signal and all equipment to turn off the power and keep the signal in a non-enabled state;

[0108] Step 5: Output the abnormal prompt information of the upgrade process.

[0109] For the convenience of description, the above five steps can be combined for explanation.

[0110] When it is determined that the current system advanced configuration and power interface status is that all devices are shut down, obtain the upgrade operation statistics flag. When the upgrade operation statistics flag is enabled, obtain the count result and determine whether the count result is greater than or equal to the preset value. If not, it means that the number of unfinished firmware refreshes is within the normal range, and the auxiliary power signal and the device all power off retention signal are controlled to be in the non-enabled state. If so, it means that the number of unfinished firmware refreshes is within the abnormal range. The firmware refresh failure may be caused by the system's own abnormality, and the upgrade process abnormal prompt information is output. By setting the upper limit of the upgrade operation statistics, when the upper limit of the upgrade statistics is exceeded, the upgrade process abnormal prompt information is output, thereby prompting the user that the firmware refresh is abnormal, which is convenient for the user to conduct troubleshooting in time.

[0111] It should be noted that the preset value can be set and adjusted according to actual conditions, and the embodiment of the present invention does not limit this. For example, it can be set to 3.

[0112] In a specific embodiment of the present invention, the method may further include the following steps:

[0113] When it is detected that the upgraded basic input / output system firmware in the flash memory is successfully refreshed to the synchronous static random access memory, the upgrade flag bit and the upgrade operation statistics flag bit are both converted from an enabled state to a disabled state, and the counting result is cleared.

[0114] When it is detected that the basic input-output system firmware that has been upgraded in the flash memory is successfully refreshed to the synchronous static random access memory, it means that the firmware refresh task has been completed, and the upgrade flag bit and the upgrade operation statistics flag bit are both converted from the enabled state to the disabled state, and the counting result is cleared. By timely converting the upgrade flag bit and the upgrade operation statistics flag bit from the enabled state to the disabled state after the basic input-output system firmware is successfully refreshed to the synchronous static random access memory, and clearing the counting result, interference with the subsequent newly generated firmware refresh tasks is avoided, and accurate recording of the firmware refresh status is achieved.

[0115] In a specific implementation of the present invention, when it is detected that the basic input / output system firmware upgrade in the flash memory is completed, obtaining the current system advanced configuration and power interface status may include the following steps:

[0116] When it is detected that the basic input and output system firmware in the flash memory is upgraded after the system management interrupt is triggered, the current system advanced configuration and power interface status are obtained.

[0117] When it is detected that the basic input and output system firmware in the flash memory is upgraded by triggering the system management interrupt, the current system advanced configuration and power interface state are obtained. By triggering the system management interrupt to upgrade the basic input and output system firmware in the flash memory, the in-band upgrade of the basic input and output system firmware is realized.

[0118] In a specific implementation of the present invention, when it is detected that the basic input / output system firmware upgrade in the flash memory is completed, obtaining the current system advanced configuration and power interface status may include the following steps:

[0119] When it is detected that the baseboard management controller has completed refreshing the new version of the basic input and output system firmware to the flash memory, the current system advanced configuration and power interface state are obtained.

[0120] When it is detected that the baseboard management controller (BMC) has completed refreshing the new version of the basic input and output system firmware to the flash memory, the current system advanced configuration and power interface status are obtained. By using the baseboard management controller to refresh the new version of the basic input and output system firmware to the flash memory, the out-of-band upgrade of the basic input and output system firmware is realized, such as the basic input and output system firmware can be remotely managed and upgraded through the Internet Protocol (IP), which improves the user experience.

[0121] Corresponding to the above method embodiment, the present invention further provides a firmware refresh device. The firmware refresh device described below and the firmware refresh method described above can refer to each other.
