[0033] To enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0034] Term explanation:

[0035] BIOS: Base Input / Output System, the basic input and output system. BIOS is a key software layer between computer hardware and the operating system, used to initialize hardware devices, start the operating system, and provide runtime services. BIOS is the first software in the computer startup process. It runs when the computer is powered on, completes hardware initialization and self-check, and boots the operating system. Users can configure hardware parameters such as startup order, clock settings, and memory configuration through the BIOS setup interface (usually entered by pressing a specific key during startup).

[0036] VMD: Volume Management Device, the volume management device. VMD is a technology introduced by Intel, mainly used to manage and control NVMe solid-state drives (SSDs) connected to the PCIe bus.

[0037] BMC: Baseboard Management Controller, the baseboard management controller, usually integrated on the server motherboard, is used to monitor and manage the hardware status of the server. The BMC runs independently of the host system and has its own processor, memory, and operating system, and can work properly even when the server is turned off.

[0038] PCIE: Peripheral Component Interconnect Express, a high-speed serial computer expansion bus standard, is widely used to connect the computer motherboard to various expansion cards (such as graphics cards, network cards, storage devices, etc.).

[0039] NVMe: Non-Volatile Memory Express, a non-volatile memory host controller interface specification, is a logical device interface specification.

[0040] In a server system, VMD (Volume Management Device) is a technology used to manage NVMe (Non-Volatile Memory Express) solid-state drives. VMD requires the coordinated support of hardware, BIOS (Base Input / Output System), and the operating system. In terms of hardware, the NVMe SSD (Solid State Drive) is directly managed through the PCIe (Peripheral Component Interconnect Express) root port of the CPU (Central Processing Unit). Each root port consists of 16 PCIe channels, forming a VMD domain. The BIOS needs to support the VMD function and correctly configure the PCIe channels, and the operating system needs to support the VMD driver to achieve management. Due to the diversity of customer requirements, the BIOS cannot default to enabling the VMD function for all ports, otherwise it may cause abnormal recognition of other PCIe devices.

[0041] In the related art, in a server environment, if different numbers of NVMe solid-state drives (SSDs) need to be configured for different customers, and these drives need to be connected to the PCIe slots under the pending CPU slots, it can be achieved by reasonably planning the PCIe topology. For example, the customer requirements are as follows: Customer A needs 4 NVMe drives, and these drives are connected to the P0 slot of CPU0; Customer B needs 8 NVMe drives, and these drives are connected to the P5 slot of CPU0. Assume that the server supports multiple CPUs and multiple PCIe slots, and each CPU has multiple PCIe root ports that can be connected to multiple NVMe drives; First, use a PCIe expansion card (such as a PCIe adapter card that can be connected to multiple NVMe drives) to connect 4 NVMe drives to the P0 slot of CPU0; Use a PCIe expansion card that supports 8 NVMe drives to connect 8 NVMe drives to the P5 slot of CPU0. Then, by manually enabling the VMD function in the BIOS SETUP or by enabling the VMD function through a custom script, in the above way, different numbers of NVMe drives can be configured for different customers and ensure that they are connected to the PCIe slots under the specified CPU slots, and this configuration method can meet the personalized needs of customers.

[0042] However, by manually enabling the VMD function in the BIOS SETUP or by enabling the VMD function through a custom script, however, manual enabling requires guidance from R & D personnel, and custom scripts require strict evaluation of customer requirements and NVMe insertion ports. Both of these methods have the problems of high professional requirements and slow response.

[0043] Based on the above problems, the embodiments of the present application provide a function configuration method applied to the basic input / output system. Combining the execution process of the function configuration method, the method is described in detail (technical terms involved must be explained).

[0044] Refer to Figure 1 As shown, the function configuration method provided by the embodiments of the present invention includes the following steps:

[0045] S11. In response to an option configuration command input by a user, determine an enabling policy for the volume management device (VMD) function during the BIOS startup process.

[0046] Among them, the enabling policy includes: turning off the VMD function, turning on the VMD function, and customizing the enabling of the VMD function.

[0047] Specifically, the BIOS determines the enabling policy of the VMD function in the BIOS startup process in response to the option configuration command input by the user. It should be noted that the VMD function of all PCIE ports is default disabled when the server is powered on. Before determining the enabling policy of the volume management device (VMD) function in the BIOS startup process in response to the option configuration command input by the user, a new VMD Configuration Mode option can be added in the Socket Configuration interface of the BIOS SETUP. The option mapstring is vmdConfMode, and this option is used to control the VMD enabling policy during the startup process.

[0048] The optional values of the VMD Configuration Mode option include 0: Disable, 1: Enable, 2: Custom. Among them, Disable means that the VMD function is default disabled; Enable means that the VMD function of all CPU PE ports that can be directly connected to NVMe is default enabled; Custom means that the VMD is enabled according to the CPU PE ports set by the customer. The default setting is Disable, that is, the VMD function is default disabled, and the current value and default value of the option are stored in the NVRAM.

[0049] The user can modify the VMD function configuration policy in the following three ways. One way is to find the "Socket Configuration" or a similar option in the BIOS setup interface. This option is usually located under the "Advanced" or "System Configuration" menu. In the "Socket Configuration" menu, find the "VMD Configuration Mode" option, and according to the customer's needs, select the appropriate value of the VMD Configuration Mode option. The option values include: Disabled: Disable the VMD function; Enabled: Enable the VMD function; Custom: Customize the VMD function. After the user inputs the required option configuration, save and restart to take effect. This way can achieve modification for a single machine. Another way is to enter the OS or Shell and use the SCE tool to modify the option value to 0, 1, or 2 through the mapstring vmdConfMode, and restart the system to take effect. This way can achieve batch modification. Another way is to use the redfish tool to modify the option and restart the system to take effect. This way can achieve modification for a single machine and can also achieve batch modification.

[0050] In some embodiments, the above step S11 (determining the enabling policy of the volume management device VMD function in the BIOS startup process) further includes:

[0051] (1) When the enabling policy of the VMD function is to enable the VMD function, poll each preset port of each CPU to be enabled and obtain the bandwidth allocation of each preset port.

[0052] Among them, the preset port is the PCIe root port used by the CPU to connect to external devices.

[0053] Specifically, when the enabling policy of the VMD function is to enable the VMD function, that is, by default, enable the VMD function of all CPU PEports that can be directly connected to NVME. Obtain the list of all PEports of the CPU through the system management tool. The ports included in the PEport list are the PCIe root ports used by the CPU to connect to external devices. For each PEport, obtain its bandwidth allocation by reading the hardware register or the system management tool. The bandwidth allocation may include, but is not limited to, modes such as x4x4x4x4, x4x4xxx8, xxx8x4x4, etc.

[0054] (2) Determine whether to enable the VMD function of the corresponding preset port according to the bandwidth allocation of each preset port.

[0055] Optionally, the above step (2) can be implemented in the following way:

[0056] If the bandwidth allocation of the target preset port meets the preset conditions, enable the VMD function at the target position.

[0057] Among them, the preset conditions include, but are not limited to, x4x4x4x4, x4x4xxx8, xxx8x4x4.

[0058] Specifically, if the bandwidth allocation of the PEport meets a specific mode (such as x4x4x4x4, x4x4xxx8, xxx8x4x4), then automatically enable the VMD function at the corresponding x4 position. The specific operations include: checking the VMDEnable status of the current port; if the VMDEnable status is off, set it to the on state; save the configuration and restart the machine.

[0059] Enable the VMD function of the corresponding preset port through automatic configuration, reducing the complexity and error rate of manual settings.

[0060] Optionally, the above step S11 (determine the enabling policy of the volume management device VMD function during the BIOS startup process) further includes:

[0061] When the enabling policy of the VMD function is to disable the VMD function, by default, disable the VMD function of all preset ports.

[0062] S12. When the enabling policy of the VMD function is to customize the enabling of the VMD function, send a query command to the management controller.

[0063] Among them, the query command is used to query the VMD function information to be enabled from the management controller; the VMD function information to be enabled is stored in the VMD enabling list. Customizing the enabling of the VMD function can be understood as customizing which ports' VMD functions to enable according to customer needs.

[0064] Specifically, when the enabling policy of the VMD function is to customize the enabling of the VMD function, send a query command to the management controller. The query command is used to query the stored VMD function information to be enabled from the management controller. The VMD information to be enabled includes the flag bit _VMD_, the number of the CPU socket to be enabled, the resource PEport supported by the CPU, and the resource index number Index.

[0065] S13. Receive the VMD function information to be enabled sent by the management controller.

[0066] Specifically, the BIOS receives the VMD function information to be enabled sent by the management controller.

[0067] S14. According to the VMD function information to be enabled, enable the VMD function of the corresponding preset port.

[0068] Among them, the VMD enabling list includes the preset port indexes of the VMD function to be enabled.

[0069] Optionally, the above step S14 (According to the VMD function information to be enabled, enable the VMD function of the corresponding preset port) can be implemented through the following steps:

[0070] A. Traverse each preset port index in the VMD enabling list.

[0071] Specifically, the customer fills in the PEport indexes that need to enable the VMD function in the VMD enabling list according to the requirements. For example, VmdEnableList can be an array or a list that stores the port indexes that need to enable the VMD function. Each PEport index in VmdEnableList is taken out sequentially through a loop structure.

[0072] B. Determine whether the bandwidth corresponding to each preset port index is the preset bandwidth in turn.

[0073] Among them, the preset bandwidth can be set according to the actual situation. For example, the preset bandwidth is x4.

[0074] Specifically, for each PEport index, obtain its bandwidth allocation through the system management tool or the hardware interface. If the bandwidth allocation is not x4, skip the current port and continue to process the next port.

[0075] C. If the bandwidth corresponding to the target preset port index is the preset bandwidth, enable the VMD function of the target preset port.

[0076] Specifically, if the bandwidth of the PEport is x4, set the VMDEnable of the corresponding PEport to 1 through the system management tool or the hardware interface, that is, enable the VMD function. Repeat the above steps until all entries in the VmdEnableList are processed, and complete the configuration of all PEports that need to enable the VMD function.

[0077] Through this automated configuration method based on customer-defined settings, the complexity and error rate of manual settings are reduced, and the reliability and performance of the system are improved. Through automatic detection and configuration, it is ensured that all eligible PEports can correctly enable the VMD function, thereby optimizing the performance and management capabilities of the device.

[0078] The function configuration method provided by the embodiments of the present disclosure determines the enabling policy of the volume management device (VMD) function during the BIOS startup process in response to an option configuration command input by the user. When the enabling policy is to customarily enable the VMD function, a query command is sent to the management controller. The query command is used to query the information of the VMD function to be enabled from the management controller, receive the information of the VMD function to be enabled sent by the management controller, and enable the VMD function of the corresponding preset port according to the information of the VMD function to be enabled. Since the enabling policy includes disabling the VMD function, enabling the VMD function, and customarily enabling the VMD function, multiple flexible VMD function enabling configuration options are provided for the user, enabling the user to configure the enabling policy of the VMD function by themselves without relying on the R & D personnel to provide scripts or manually enter the BIOS settings, thereby improving the enabling configuration efficiency of the VMD function and avoiding customer complaints caused by slow response from technical support personnel. Additionally, since the information of the VMD function to be enabled is stored in the user-defined VMD enabling list, the user can store all the port information that needs to enable the VMD function in the VMD enabling list in advance. When the enabling policy is to customarily enable the VMD function, a query command is sent to the management controller to query the information of the VMD function to be enabled from the VMD enabling list of the management controller, and the VMD function of the corresponding preset port is enabled according to the information of the VMD function to be enabled, thereby achieving batch setting, improving the enabling configuration efficiency of the VMD function, effectively reducing the human input, and enhancing the customer experience.

[0079] Based on the above problems, an embodiment of the present application provides a function configuration method, which is applied to a management controller. Combining with the execution process of the function configuration method, the method is described in detail.

[0080] S21. Receive a query command sent by the BIOS.

[0081] Wherein, the query command is used to query the VMD function information to be enabled from the management controller; the VMD function information to be enabled is stored in the VMD enable list.

[0082] Specifically, the management controller receives the query command sent by the BIOS.

[0083] S22. In response to the query command sent by the BIOS, send the VMD function information to be enabled to the BIOS, so that the BIOS can enable the VMD function of the corresponding preset port according to the VMD function information to be enabled.

[0084] Specifically, when the management controller receives the query command, it parses and determines whether the information header is _VMD_. If the information header is _VMD_, a new structure is added to store the parsed information. For example, the structure can be:

[0085] typedef struct{UINT16 Socket;

[0086] UINT16 Port;

[0087] UINT16 Index;

[0088] }VMD_ENABLE_LIST;

[0089] And set the variable VmdEnableList to store the information of the VMD function enabled by the customer. Then, obtain the VMD function information to be returned to the BIOS from the specified location of the non-volatile memory according to the requirements, fill the VMD function information to be enabled into VmdEnableList, and after escaping the information in VmdEnableList, return it to the BIOS according to the specified rules.

[0090] In some embodiments, before performing the above step S21 (receiving the query command sent by the BIOS), the following steps may also be performed:

[0091] 1) In response to the write command input by the user, parse the write command to obtain the first VMD function information to be enabled.

[0092] Among them, the write command is used to write the information that needs to enable the VMD function manually set by the customer into the memory of the management controller, that is, the first VMD function information to be enabled.

[0093] Optionally, the above step 1) (parsing the write command to obtain the first VMD function information to be enabled) can be implemented in the following way:

[0094] Parse the write command and determine whether the information header is a preset character.

[0095] Among them, the preset character can be set according to the actual situation. For example, the preset character can be set to _VMD_.

[0096] If the information header is the preset character, then determine whether the parsed data is valid.

[0097] Specifically, whether the parsed data is valid can be determined according to the following conditions. For example, the maximum number of CPUs of a machine is 8 currently, so Socket is less than 8; the maximum number of PEports is 5, so its quantity is less than 5; the minimum unit of index is 2, so it is restricted to be less than 8.

[0098] If the parsed data is valid, then obtain the first VMD function information to be enabled.

[0099] Specifically, parse the write command, determine whether the information header is a preset character. If the information header is the preset character, then further determine whether the parsed data is valid. If the parsed data is valid, then obtain the first VMD function information to be enabled.

[0100] By determining whether the information header is a preset character, commands that meet the requirements can be quickly screened out, avoiding invalid or incorrect commands from entering the subsequent processing flow, thereby reducing the waste of system resources. Further determining whether the parsed data is valid ensures that only verified data will be processed, avoiding system failures or incorrect operations caused by incorrect data. Only when both the information header and the data meet the requirements will the first VMD function information to be enabled be obtained, enabling the system to quickly locate the valid information that truly needs to be processed.

[0101] 2) Read the VMD enable list from the memory of the management controller.

[0102] 3) Determine whether the first VMD function information to be enabled is stored in the VMD enable list.

[0103] 4) If the first VMD function information to be enabled is not stored in the VMD enable list, then write the first VMD function information to be enabled into the memory of the management controller.

[0104] Specifically, since the VMD enable list in the memory of the management controller stores information about the VMD function that the user has set to be enabled, it is determined whether the first VMD function information to be enabled currently obtained is stored in the VMD enable list. If the first VMD function information to be enabled is not stored in the VMD enable list, the first VMD function information to be enabled is written into the memory of the management controller.

[0105] Exemplarily, when the management controller receives a write command, it parses and determines whether the information header is _VMD_. If the information header is _VMD_, a new structure is added to store the parsed information. For example, the structure can be:

[0106] typedef struct{UINT16 Socket;

[0107] UINT16 Port;

[0108] UINT16 Index;

[0109] }VMD_ENABLE_MESSAGE;

[0110] And a variable VmdEnableMessage is set to store the newly added information for enabling the VMD function. The information of the write command is parsed in sequence, and each field is two bytes (BYTE). The validity of the data is judged according to the actual situation (including Socket less than 8, Port information less than 5, and Index information less than 8). If the data is invalid, return 02 and jump to the end; if the data is valid, assign values to Socket, Port, and Index in sequence, and store the information in VmdEnableMessage; read the information at the specified position in the EEPROM, return the stored number N, and store it in EepromVmdList. Compare the information in VmdEnableMessage with the information in EepromVmdList. If the first VMD function information to be enabled currently obtained already exists, return 01 to indicate the existence of the currently set information; if the first VMD function information to be enabled currently obtained does not exist, write the information in EepromVmdList to the (N + 1)th position and return the information 00 to indicate that the information for enabling the VMD has been successfully stored in the EEPROM.

[0111] In some instances, before performing the above step S21 (receiving the query command sent by the BIOS), the following steps can also be performed:

[0112] In response to the delete command input by the user, the delete command is parsed to obtain the second VMD function information to be enabled.

[0113] Among them, the deletion command is used to delete the information that does not need to enable the VMD function, that is, the second piece of information to be enabled with the VMD function.

[0114] Read the VMD enable list from the memory of the management controller.

[0115] Determine whether the second piece of information to be enabled with the VMD function is stored in the VMD enable list.

[0116] If the second piece of information to be enabled with the VMD function is not stored in the VMD enable list, delete the second piece of information to be enabled with the VMD function from the memory of the management controller.

[0117] Specifically, the management controller responds to the deletion command input by the user, parses the deletion command to obtain the second piece of information to be enabled with the VMD function, reads the VMD enable list from the memory of the management controller, determines whether the second piece of information to be enabled with the VMD function is stored in the VMD enable list, and if the second piece of information to be enabled with the VMD function is not stored in the VMD enable list, deletes the second piece of information to be enabled with the VMD function from the memory of the management controller.

[0118] Exemplarily, when the management controller receives a deletion command, it parses and determines whether the information header is _VMD_. If the information header is _VMD_, a new structure is added to store the parsed information. For example, the structure can be:

[0119] typedef struct{UINT16 Socket;

[0120] UINT16 Port;

[0121] UINT16 Index;

[0122] }VMD_ENABLE_MESSAGE;
