[0061] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0062] Reference Figure 1 , shows a flowchart of a method for obtaining display information provided by an embodiment of the present invention, which is applied to a BMC system. The BMC system is connected to a server through an out-of-band management interface. The server is equipped with a BIOS system. The BMC system is provided with a shared memory area. The method may specifically include the following steps:

[0063] Step 101, when a query instruction is received, determine whether the update flag in the shared memory area is set to a preset flag; wherein, the preset flag is set by the BIOS system when transmitting the first display information to the shared memory area; the first display information is the display information of this startup that is updated when the BIOS system power-on self-test ends.

[0064] The embodiments of the present invention can be applied to the BMC system. The BMC (Baseboard Management Controller) is the core functional system of the server, responsible for core functions such as hardware status management, operating system management, health status management, and power consumption management. In short, the BMC system is equivalent to an external management and control system, facilitating server management. Even if the BMC system is abnormal, it will not affect the current operation of the server.

[0065] Specifically, during the operation and maintenance management of the server, the BMC system can communicate with the server through the out-of-band management interface, so that the BMC system can monitor and manage server asset information in real time based on the out-of-band management interface. For example, it can check the configuration and operating status of devices such as processors, memory, and hard disks, query the firmware version information such as BIOS or BMC or CPLD (Complex Programmable Logic Device), or perform version upgrades and upgrades.

[0066] Servers are equipped with a BIOS (Basic Input / Output System). The BIOS is a set of programs embedded in a ROM (Read Only Memory Image) chip on the computer's motherboard. The BIOS stores the computer's most important basic input / output (BIO) programs, post-boot self-test programs, and system startup programs. Its primary function is to provide the most basic and direct hardware configuration and control for the computer. Simply put, the BIOS is the basic input / output system that controls server startup. It is a server's most fundamental and indispensable system. A normal BIOS is required for the OS to function properly.

[0067] This embodiment of the present invention utilizes a novel H2B (Host to BMC) shared memory interaction method. The H2B shared memory can be the BMC system's DRAM (Dynamic Random Access Memory). After the host sends display information, the BMC system does not need to process it immediately; it only needs to obtain the display information upon receiving a user query. The host includes the BIOS system, so the H2B shared memory area can be considered the shared memory area for interaction between the BIOS system and the BMC system. In other words, the shared memory area provided by the BMC system is readable and writable by both the BMC system and the BIOS system.

[0068] In an embodiment of the present invention, if a user wishes to query display information, the user may enter a query command on the BMC system's web page. The shared memory area provided by the BMC system has an Update Flag. Upon receiving the query command, the BMC system may first check whether the Update Flag is set to a preset value.

[0069] Among them, the preset identifier is set by the BIOS system when transmitting the first display information to the shared memory area Share Memory, and the first display information is the display information of this startup that is updated at the end of the BIOS system POST (Power On Self Test). Specifically, the server is turned on and powered on until the BIOS system POST ends, so that the dmesg information of this startup is updated. Then the BIOS system can use the CRC (Cyclic Redundancy Check) verification method to check whether the interaction function with the BMC system is normal. If the interaction function between the BIOS system and the BMC system is normal, then the BIOS system can transmit the dmesg information of this startup as the first dmesg information to the shared memory area Share Memory. At this time, the BIOS system can set the update flag Update Flag in the shared memory area Share Memory and set the update flag Update Flag to the preset identifier.

[0070] It's important to note that dmesg (display message) can be used to display the contents of the kernel ring buffer. The kernel stores various messages in dmesg. During system boot, the kernel fills the kernel ring buffer with information related to hardware and module initialization. The kernel (operating system kernel) stores boot information in the ring buffer. Boot information is saved in a file named dmesg in the / var / log directory, forming dmesg information, which in turn forms display information. The information displayed in the kernel ring buffer is often very useful for diagnosing system problems.

[0071] When running dmesg, it displays a large amount of boot information, including but not limited to: hard disk operating mode, network card configuration information, ACPI (Advanced Configuration and Power Interface) detection information, memory allocation, processor information, etc., including mce log (used to check hardware errors on Linux system), hardware devices, system architecture, etc.

[0072] Because dmesg can display multiple operating levels and a large amount of startup information, such as system architecture, CPU (Central Processing Unit), mounted hardware, RAM (Random Access Memory), etc., dmesg contains a lot of content, has a capacity of 0.1MB, and has a large transmission volume. Therefore, the embodiment of the present invention can set up multiple shared memory areas, which can reach megabytes, thereby meeting the need for transmitting large amounts of data at one time.

[0073] In an embodiment of the present invention, each shared memory region may correspond to an Update Flag, and different types of dmesg messages may be stored in different shared memory regions. Therefore, the BIOS system may, based on the type of the first dmesg message, transmit the first dmesg message to the corresponding shared memory region, then set the Update Flag in the corresponding shared memory region to a preset identifier.

[0074] Step 102: If the update flag is set to the preset flag, it is determined that the server is in a normal state.

[0075] In the embodiment of the present invention, the BMC system checks whether the Update Flag is set to a preset flag. If the Update Flag is set to the preset flag, it can be determined that the server is in a normal state, that is, the state after the POST is completed, indicating that the display information of this startup has been successfully updated.

[0076] In one example, the preset flag can be set to 1. When Update Flag = 1, the BMC system can determine that the server is in a normal state. It should be noted that the preset flag is pre-negotiated between the BMC system and the BIOS system. The preset flag can be set according to actual conditions. The embodiment of the present invention does not limit the preset flag.

[0077] Step 103: When the server is in a normal state, obtain the first display information from the shared memory area.

[0078] In the embodiment of the present invention, when the server is in a normal state, it means that the display information of this startup has been updated successfully, then the BMC system can directly obtain the interactive content from the shared memory area Share Memory. The interactive content is the first display information transmitted by the BIOS system.

[0079] Step 104: determine the first display information as first target display information for the query instruction, and display the first target display information.

[0080] In an embodiment of the present invention, after obtaining the first display information, the BMC system may determine the first display information as the first target display information for the query instruction, and then display the first target display information to the user, allowing the user to understand system startup and operation information. The first target display information may include at least one of the following: mce log, mounted hardware, CPU, and system architecture.

[0081] In summary, in an embodiment of the present invention, the BMC system is provided with a shared memory area. When a query instruction is received, the BMC system determines whether the update flag in the shared memory area is set to a preset flag. The preset flag is set by the BIOS system when transmitting the first display information to the shared memory area. The first display information is the display information of the current startup that is updated at the end of the BIOS system power-on self-test. If the update flag is set to the preset flag, the BMC system determines that the server is in a normal state. When the server is in a normal state, the BMC system obtains the first display information from the shared memory area. The BMC system determines the first display information as the first target display information for the query instruction and displays the first target display information. The embodiment of the present invention provides a shared memory area through the BMC system. Both the BMC system and the BIOS system have readable and writable access. Thus, the BMC system can obtain the display information transmitted by the BIOS system through the shared memory area, thereby realizing the acquisition of display information based on an out-of-band management method. The out-of-band management method does not affect the current operation of the server, and thus can greatly improve the efficiency of the operation and maintenance management of the server.

[0082] Reference Figure 2 , shows a flowchart of a method for obtaining display information provided by an embodiment of the present invention, which is applied to a BMC system. The BMC system is connected to a server via an out-of-band management interface. The server is equipped with a BIOS system. The BMC system includes a shared memory area and a non-shared memory area. The non-shared memory area stores second display information. The method may specifically include the following steps:

[0083] Step 201, when a query instruction is received, determines whether the update flag in the shared memory area is set to a preset flag; wherein, the preset flag is set by the BIOS system when transmitting the first display information to the shared memory area; the first display information is the display information of this startup that is updated when the BIOS system power-on self-test ends.

[0084] In the embodiment of the present invention, it can be applied to the BMC system. The BMC system is equivalent to an external management and control system, which is convenient for managing servers. Even if the BMC system is abnormal, it will not affect the current operation of the server.

[0085] Specifically, during the operation and maintenance management of the server, the BMC system can communicate with the server through the out-of-band management interface, so that the BMC system can monitor and manage server asset information in real time based on the out-of-band management interface. For example, it can check the configuration and operating status of devices such as processors, memory, and hard disks, query the firmware version information such as BIOS, BMC, or CPLD, or perform version upgrades and upgrades.

[0086] The server is deployed with a BIOS system, which is equivalent to a basic input and output system that controls the server startup. It is the most basic and indispensable system of the server. Only when the BIOS system is normal can the OS system be entered.

[0087] The BMC system provides a shared memory area, Share Memory, which is readable and writable by both the BMC system and the BIOS. Therefore, when the BIOS system transmits the current boot display information to the BMC system, it can do so through the Share Memory area. The Share Memory area has an Update Flag.

[0088] In a specific implementation, the server boots up and powers on until the BIOS system POST completes, completing the update of the display information for this boot. The BIOS system can then use a CRC check method to verify that the interaction with the BMC system is functioning properly. If the interaction between the BIOS system and the BMC system is functioning properly, the BIOS system can transmit the display information for this boot as the first display information to the shared memory area. At this point, the BIOS system can set the Update Flag to a preset value.

[0089] It should be noted that both the BIOS system and the BMC system can allocate resources in advance and establish interaction standards and Struct structures, so that both the BIOS system and the BMC system can access the shared memory area.

[0090] In an embodiment of the present invention, if a user wishes to query display information, the user may enter a query command on the BMC system's web page. Upon receiving the query command, the BMC system may first check whether an Update Flag in the shared memory area Share Memor is set to a preset flag. Based on the Update Flag, the BMC system may then determine whether to obtain the first display information from the shared memory area Share Memor or the second display information from the non-shared memory area EEPROM.

[0091] It should be noted that EEPROM (Electrically Erasable Programmable Read-Only Memory) is a storage chip that maintains data after a power outage. Therefore, the non-shared EEPROM memory area is the non-volatile memory area of ​​the BMC system, while the shared memory area is the volatile memory area of ​​the BMC system.

[0092] Step 202: If the update flag is set to the preset flag, it is determined that the server is in a normal state; or if the update flag is not set to the preset flag, it is determined that the server is in an abnormal state; wherein the abnormal state includes a shutdown state or a downtime state.

[0093] Since dmesg information can only be obtained through in-band management in the prior art, users need to operate the server system normally to read dmesg information. When the in-band management method is used to view it under the OS system, however, dmesg information cannot be obtained when the system is down or the OS system has not been entered. Therefore, the in-band management method in the prior art is limited to whether the current server is turned on or operating normally. That is, the in-band management method in the prior art can only obtain dmesg information when the server is in a normal state, but cannot obtain dmesg information when the server is in an abnormal state.

[0094] The embodiment of the present invention obtains demsg information based on an out-of-band management method. Specifically, the BMC system obtains demsg information through an out-of-band management interface. Therefore, there is no need to consider whether the current server is powered on or running normally, and there is no need to log in to the OS system. The demsg information can be obtained conveniently and quickly, thereby greatly improving the operation and maintenance management efficiency of the server.

[0095] In the embodiment of the present invention, whether the server is in a normal state or an abnormal state can be determined by whether the update flag Update Flag is set to a preset flag.

[0096] Specifically, if the update flag Update Flag is set to a preset flag, it can be determined that the server is in a normal state, that is, a state after the POST is completed, indicating that the display information of this startup has been successfully updated.

[0097] Specifically, if the Update Flag is not set to a preset value, it can be determined that the server is in an abnormal state, which may include a shutdown state or a down state. If the server is in the shutdown state, the BIOS system cannot perform a POST (power-on self-test), and thus no display information for the current startup will be displayed. If the server is in a down state, the down state will affect the BIOS system's POST process, causing the BIOS system to remain in an uncompleted POST state, and thus unable to update the display information for the current startup.

[0098] Whether in shutdown state or down state, it will affect the POST process of the BIOS system, thereby affecting the update completion of the display information of this startup, and then the data in the shared memory area Share Memor will be invalid.

[0099] In one example, the preset flag can be set to 1. When Update Flag = 1, the BMC system can determine that the server is in a normal state; when Update Flag = 0, the BMC system can determine that the server is in an abnormal state. It should be noted that the preset flag is pre-negotiated between the BMC system and the BIOS system and can be set according to actual circumstances. The embodiments of the present invention do not limit the preset flag.

[0100] Step 203: when the server is in a normal state, obtain the first display information from the shared memory area; or, when the server is in a shutdown state or a down state, obtain the second display information from the non-shared memory area; wherein, the second display information is the display information of the last startup.

[0101] In the embodiment of the present invention, when the server is in a normal state, it means that the display information of this startup has been updated successfully, then the BMC system can obtain the first display information transmitted by the BIOS system from the shared memory area Share Memory, and the first display information is the display information of this startup.

[0102] In an embodiment of the present invention, when the server is in a shutdown state or a down state, it indicates that the display information of this startup fails to be updated. Then the BMC system can obtain the second display information from the non-shared memory area EEPROM. The second display information is the display information of the last startup.

[0103] In an optional embodiment of the present invention, the method may further include:

[0104] Synchronize the first display information to the non-shared memory area.

[0105] In the embodiment of the present invention, the non-shared memory area EEPROM is a non-volatile memory area of ​​the BMC system, that is, data in the non-shared memory area EEPROM is not lost after power failure, while the shared memory area Share Memor is a volatile memory area of ​​the BMC system, that is, data in the shared memory area Share Memor is lost after power failure.

[0106] Therefore, the BMC system can synchronize the first display information with the non-shared memory area EEPROM, allowing the non-shared memory area EEPROM to retain a copy of the first display information. This allows the first display information to be used as the display information from the previous boot at the next boot. In other words, the first display information becomes the second display information at the next boot. Thus, when the server is in the shutdown or down state, although the data in the shared memory area is lost after a power outage, the data in the non-shared memory area EEPROM is not lost after a power outage. Therefore, the BMC system can retrieve the display information from the non-shared memory area EEPROM from the previous boot.

[0107] In addition, the BMC system can perform persistence processing on the shared memory area Share Memor to ensure that the data in the shared memory area Share Memor can be restored to its original state after power failure and power on again. In a specific implementation, since the first display information has been synchronized to the non-shared memory area EEPROM in advance, the first display information can be obtained from the non-shared memory area EEPROM after power failure is restored, and then the first display information can be retransmitted to the shared memory area Share Memor. Since the first display information after power failure is restored is the display information of the last startup, the BMC system can directly obtain the display information of the last startup from the shared memory area Share Memor in this way. This method requires retransmission of data after each power failure, while the data in the non-shared memory area EEPROM is not lost after power failure. Therefore, the embodiment of the present invention can preferably obtain the display information of the last startup from the non-shared memory area EEPROM.

[0108] Step 204: determine the first display information as the first target display information for the query instruction, and display the first target display information; or determine the second display information as the second target display information for the query instruction, and display the second target display information.

[0109] In an embodiment of the present invention, upon obtaining the first display information, the BMC system may determine the first display information as the first target display information for the query instruction, and then display the first target display information to the user, allowing the user to understand the current system startup and operation information. The first target display information may include at least one of the following: mce log, mounted hardware, CPU, and system architecture.

[0110] In an embodiment of the present invention, upon obtaining the second display information, the BMC system may determine the second display information as the second target display information for the query instruction and then display the second target display information to the user, allowing the user to understand the system's last startup and operation information. The second target display information may include at least one of the following: mce log, mounted hardware, CPU, and system architecture.

[0111] In an optional embodiment of the present invention, the BMC system has a web page; determining the first display information as the first target display information for the query instruction and displaying the first target display information may include the following sub-steps:

[0112] Sub-step S11, parsing the first display information according to a preset parsing rule to obtain first target display information for the query instruction;

[0113] Sub-step S12: displaying the first target display information on the Web page.

[0114] In a specific implementation, the BMC system can parse the first display information 5 obtained from the shared memory area Share Memor according to a preset parsing rule to obtain the first target display information for the query instruction. The first target display information can be the mce log, mounted hardware, CPU, system architecture, etc. The BMC system can display the information such as the mce log, mounted hardware, CPU, and system architecture on the BMC system's web page.

[0115] In an optional embodiment of the present invention, the BMC system has a web page; determining the second display information as the second target display information for the query instruction and displaying the second target display information may include the following sub-steps:

[0116] Sub-step S21, parsing the second display information according to a preset parsing rule to obtain second target display information for the query instruction;

[0117] Sub-step S22: displaying the second target display information on the Web page.

[0118] In a specific implementation, the BMC system can parse the second display information obtained from the non-shared memory area EEPROM according to preset parsing rules to obtain the second target display information for the query instruction. The second target display information can be the MCE log, mounted hardware, CPU, and system architecture, etc. The BMC system can display the MCE log, mounted hardware, CPU, and system architecture information on the BMC system web page.

[0119] In an optional embodiment of the present invention, after synchronizing the first display information to the non-shared memory area, the method may further include:

[0120] The preset flag is cleared to reset the update flag.

[0121] After synchronizing the first display information to the non-shared memory area, the BMC system may clear the preset flag, that is, reset the update flag Update Flag, thereby ensuring that the display information in the shared memory area 5 Share Memor is the latest display information.

[0122] In an optional embodiment of the present invention, the method may further include:

[0123] When a modification instruction is received, the first display information in the shared memory area is modified according to the modification instruction so that the BIOS system writes the modified first display information into the third display information when the computer is powered on next time; the third display information is the display information for the next power-on.

[0124] In an embodiment of the present invention, the display information in the shared memory area Share Memor is readable and writable. The user can not only query the first display information through the shared memory area Share Memor, but also modify the first display information through the shared memory area Share Memor, so that the BIOS system can access the modification record of the shared memory area Share Memor and write it to the latest display information when the computer is turned on next time.

[0125] In a specific implementation, if a user wishes to modify the first display information, they can enter a modification instruction on the BMC system's web page. Upon receiving the modification instruction, the BMC system modifies the first display information in the shared memory area ShareMemor according to the modification instruction. The BIOS system then accesses the modification record in the shared memory area ShareMemor and can write the modified first display information to the third display information the next time the computer is powered on. The third display information can be the display information for the next power-on.

[0126] In summary, in an embodiment of the present invention, the BMC system is provided with a shared memory area. When a query instruction is received, the BMC system determines whether the update flag in the shared memory area is set to a preset flag. The preset flag is set by the BIOS system when transmitting the first display information to the shared memory area. The first display information is the display information of the current startup that is updated at the end of the BIOS system power-on self-test. If the update flag is set to the preset flag, the BMC system determines that the server is in a normal state. When the server is in a normal state, the BMC system obtains the first display information from the shared memory area. The BMC system determines the first display information as the first target display information for the query instruction and displays the first target display information. The embodiment of the present invention provides a shared memory area through the BMC system. Both the BMC system and the BIOS system have readable and writable access. Thus, the BMC system can obtain the display information transmitted by the BIOS system through the shared memory area, thereby realizing the acquisition of display information based on an out-of-band management method. The out-of-band management method does not affect the current operation of the server, and thus can greatly improve the efficiency of the operation and maintenance management of the server.

[0127] In addition, in an embodiment of the present invention, the BMC system further includes a non-shared memory area, which stores second display information. If the update flag is not set to a preset flag, the BMC system determines that the server is in an abnormal state. The abnormal state includes a shutdown state or a down state. When the server is in the shutdown state or down state, the BMC system obtains the second display information from the non-shared memory area. The second display information is the display information from the last startup. The BMC system determines the second display information as the second target display information for the query instruction and displays the second target display information. In an embodiment of the present invention, the BMC system provides a non-shared memory area. When the update flag in the shared memory area is not set to a preset flag, it can be determined that the server is in an abnormal state. At this time, the BMC system can obtain the display information from the last startup transmitted by the BIOS system through the non-shared memory area, thereby achieving out-of-band management mode to obtain display information. The out-of-band management mode does not affect the current operation of the server, and does not require consideration of whether the current server is in a normal state or logging into the OS. Display information can be obtained conveniently and quickly, thereby greatly improving the efficiency of server operation and maintenance management.

[0128] In order to enable those skilled in the art to better understand the embodiments of the present invention, the embodiments of the present invention are described below through the following examples:

[0130] 1. The process begins;

[0131] 2. The server is powered on, and the BMC system allocates Share Memor (shared memory area) resources;

[0132] 3. The server is powered on until the BIOS system POST (power-on self-test) is completed, and the display information of this startup is updated;

[0133] 4. The BIOS system allocates Share Memor resources and checks whether the interaction function with the BMC system is normal;

[0134] 5. When the interaction function between the BIOS system and the BMC system is normal, the BIOS system transmits the display information of this boot as the first display information to the Share Memory, and the BIOS system sets the Update Flag in the Share Memory to a preset flag;

[0135] 6. The BMC system receives the user's query instruction on the web page;

[0136] 7. The BMC system determines whether the Update Flag is set to the preset flag; if not, proceed to step 8; if so, proceed to step 9;

[0137] 8. If the Update Flag is not set to the preset flag, the BMC system obtains the second display information from the EEPROM (non-shared memory area), the second display information being the display information from the last boot, parses the second display information to obtain the second target display information, and displays the second target display information on the web page; then proceeds to step 10;

[0138] 9. If the Update Flag is set to the preset flag, the BMC system obtains the first display information from the Shared Memory. The first display information is the display information for this boot. The BMC system synchronizes the first display information to the EEPROM and resets the Update Flag. The BMC system parses the first display information to obtain the first target display information and displays the first target display information on the web page. Then, the process proceeds to step 10.

[0139] 10. The process ends.
