[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on November 29, 2023, with application number 202311608727.3, and application name “Method, device, equipment and medium for displaying PCIE device startup mode”, all contents of which are incorporated by reference into this application.

[0004] With the rapid development of server technology, the usability, performance, and functionality of servers are constantly improving. In particular, efficient usability enables server operations and maintenance personnel to easily manage and work efficiently.

[0005] However, in some application scenarios, servers are connected to multiple high-speed peripheral component interconnect express (PCIE) devices, and these devices may support different boot modes. Selecting an inappropriate boot mode can lead to issues such as PCIE device misrecognition, disk or card loss, and system loss.

[0006] However, since the boot modes supported by the currently installed PCIE devices are not displayed in the device list of the Basic Input Output System (BIOS) device options and the Baseboard Management Controller (BMC) network interface, server operation and maintenance personnel can only confirm the boot modes supported by the PCIE devices one by one by looking up the user manuals and device instruction manuals of each PCIE device, which brings great trouble to server operation and maintenance personnel.

[0079] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. Furthermore, the term "and / or" in this specification indicates at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0081] The following describes in detail the method for displaying the PCIE device startup mode provided in the embodiment of the present application through embodiments and application scenarios in combination with the accompanying drawings.

[0082] Please refer to Figure 1, which is a flow chart of a method for displaying a PCIE device boot mode according to an embodiment of the present application. The method is applied to a BIOS integrated circuit. As shown in Figure 1, the method may include the following steps:

[0083] Step 101: During the BIOS initialization phase after the server is powered on, all root bridge devices are queried.

[0084] Step 102: Determine the PCIE device under each root bridge device based on the root bridge device.

[0085] Step 103: For each PCIE device, in response to determining that the PCIE device is in place, read a first preset bit of a function list and a second preset bit of a PCIE function bit in a configuration space of the PCIE device;

[0086] Step 104 : Based on the first preset position of the function list and the second preset position of the PCIE function bit, the boot modes supported by the PCIE device are displayed under the BIOS device options.

[0087] In step 101 and step 102, the root bridge device is an interface between the CPU and the PCIE topology. The PCIE devices in the PCIE topology can be found through the root bridge device.

[0088] During the BIOS device initialization phase after the server is powered on, all root bridge devices are queried, and the queried root bridge devices are stored in a linked list. The root bridge devices in the linked list are traversed to find the PCIE devices under each root bridge device.

[0089] In step 103, all the PCIE devices in place are traversed and the configuration space of the PCI device is accessed through EFI_PCI_IO_PROTOCOL. The configuration space of the PCI device includes a capability list and PCIE capability bits.

[0090] In some embodiments, the first preset bit of the function list and the second preset bit of the PCIE function bit are read through the function list (CapailityPtr) pointer of the PCIE device. The value of the first preset bit of the function list indicates whether the device supports the Unified Extensible Firmware Interface (UEFI) mode. For example, if the value of the first preset bit is 1, it means that the device supports UEFI mode, which means that the device supports UEFI mode and Legacy mode. If the value of this bit is not 1, it means that the device only supports Legacy mode. The second preset bit of the PCIE function bit indicates whether the device supports UEFI mode. For example, if the second preset bit is 1, it means that the device supports UEFI mode, which means that the device supports UEFI mode and Legacy mode. If the value of this bit is not 1, it means that the device only supports Legacy mode.

[0091] Therefore, in step 104, the boot mode supported by the PCIE device can be determined based on the first preset bit of the function list and the second preset bit of the PCIE function bit, and then the boot mode supported by the PCIE device is displayed under the BIOS device option.

[0092] In some embodiments, the first preset bit is the fourth bit, and the second preset bit is the seventh bit. The fourth bit of the function list indicates whether the device supports the Unified Extensible Firmware Interface (UEFI) mode. If the bit is 1, it indicates that the device supports UEFI mode, which means that the device supports UEFI mode and Legacy mode. Otherwise, it only supports Legacy mode. The seventh bit of the PCIE function bit indicates whether the device supports UEFI mode. If the bit is 1, it indicates that the device supports UEFI mode, which means that the device supports UEFI mode and Legacy mode. Otherwise, it only supports Legacy mode.

[0093] The embodiment of the present application provides a method for displaying PCIE device boot modes. First, the BIOS integrated circuit queries all root bridge devices during the BIOS initialization device phase after the server is powered on. Then, based on each root bridge device, the PCIE devices under the root bridge device are determined, and all PCIE devices can be found. Then, for each PCIE device, in response to determining that the PCIE device is in place, the first preset bit of the function list and the second preset bit of the PCIE function bit in the configuration space of the PCIE device are read. Finally, the first preset bit of the function list indicates whether the device supports UEFI mode, and the second preset bit of the PCIE function bit indicates whether the device supports UEFI mode. Based on the first preset bit of the function list and the second preset bit of the PCIE function bit, the boot mode supported by the PCIE device can be determined, and the boot mode supported by the PCIE device can be displayed under the BIOS device options. The boot modes supported by the currently installed PCIE device can be displayed under the BIOS device options, so that server operation and maintenance personnel can simply, quickly and intuitively determine the boot modes supported by the currently installed PCIE device, thereby deciding the most appropriate boot mode and avoiding problems such as PCIE device unrecognition, disk drop, card drop, and system loss caused by selecting an inappropriate boot mode.

[0094] In an exemplary embodiment, step 104 may include the following sub-steps:

[0095] Step 1041: Perform an AND operation on the first preset bit of the function list and the second preset bit of the PCIE function bit to obtain an AND operation result.

[0096] Exemplarily, the first preset bit of the function list is set to 1, and the second preset bit of the PCIE function bit is also set to 1, then 1&1=1, that is, the result of the AND operation is 1.

[0097] The first preset bit of the function list is set to 0, and the second preset bit of the PCIE function bit is also set to 0, so 0&0=0, that is, the result of the AND operation is 0.

[0098] Step 1042: Assign the result of the AND operation to a preset global variable.

[0099] For example, the preset global variable may be DeviceSupportBootModeValue. The global variable DeviceSupportBootModeValue is declared, and the result of the AND operation is assigned to the global variable DeviceSupportBootModeValue.

[0100] Step 1043: Generate a file in a preset format based on the device information of each PCIE device; the device information includes preset global variables.

[0101] For example, the file in the preset format may be a cJSON file, and the device information of each PCIE device including the global variable DeviceSupportBootModeValue is created into a cJSON file. cJSON is a JavaScript Object Notation (JSON) library based on C language.

[0102] Step 1044: Under the BIOS device option, create a topology structure of each PCIE device based on the device information of each PCIE device in a file in a preset format.

[0103] Exemplarily, in response to determining that the BIOS is booted to the BIOS device option, a topology structure of each PCIE device is automatically created according to the device information of each PCIE device in the cJSON file.

[0104] Step 1045: Create a BIOS option for the boot mode supported by each PCIE device under the topology structure of each PCIE device.

[0105] Exemplarily, a BIOS option for the boot mode supported by the device is automatically created under each PCIE device.

[0106] Step 1046: Determine the boot mode supported by the PCIE device based on the value of the preset global variable under the BIOS option of the boot mode supported by each PCIE device.

[0107] In some embodiments, in response to determining that the value of a preset global variable under the BIOS option for the boot mode supported by the PCIE device is 1, it is determined that the boot modes supported by the PCIE device are UEFI mode and Legacy mode; in response to determining that the value of a preset global variable under the BIOS option for the boot mode supported by the PCIE device is 0, it is determined that the boot mode supported by the PCIE device is Legacy mode.

[0108] For example, if the global variable DeviceSupportBootModeValue under the BIOS option of the device-supported boot mode of the PCIE device is 1, it indicates the device is in UEFI mode, which means that the boot modes supported by the PCIE device are UEFI mode and Legacy mode. If the global variable DeviceSupportBootModeValue under the BIOS option of the device-supported boot mode of the PCIE device is 0, it indicates that the device does not support UEFI mode, which means that the boot mode supported by the PCIE device is Legacy mode.

[0109] Step 1047: Under the BIOS option of the boot mode supported by each PCIE device, the boot mode supported by the PCIE device is displayed.

[0110] Exemplarily, in response to determining that the boot modes supported by the PCIE device are UEFI mode and Legacy mode, under the BIOS option of the boot modes supported by the PCIE device, the boot modes supported by the PCIE device are displayed as UEFI mode and Legacy mode. If the boot mode supported by the PCIE device is Legacy mode, then under the BIOS option of the boot modes supported by the PCIE device, the boot mode supported by the PCIE device is displayed as Legacy mode.

[0111] In this embodiment, first, the result of the AND operation of the first preset bit of the function list and the second preset bit of the PCIE function bit is assigned to a preset global variable; then, a file in a preset format is generated based on the device information of each PCIE device including the preset global variable; then, under the BIOS device option, based on the device information of each PCIE device in the preset format file, a topology structure of each PCIE device is created; under the topology structure of each PCIE device, a BIOS option of the boot mode supported by the device of each PCIE device is created; finally, based on the value of the preset global variable under the BIOS option of the boot mode supported by the device of each PCIE device, the boot mode supported by the PCIE device is determined, thereby realizing that under the BIOS option of the boot mode supported by the device of each PCIE device, the boot mode supported by the PCIE device is displayed.

[0112] In an example embodiment, the method further includes: in response to determining that the startup mode of the PCIE device is adjusted to the target startup mode, checking whether the target startup mode is consistent with the startup mode supported by the PCIE device; in response to determining that the target startup mode is consistent with the startup mode supported by the PCIE device, storing the target startup mode in a dynamic area of ​​a non-volatile random access memory, so that the PCIE device uses the target startup mode to start up the next time it starts up.

[0113] Exemplarily, in response to determining that the boot mode of the PCIE device is adjusted to UEFI mode, a check is performed to determine whether the UEFI mode is consistent with the boot modes supported by the PCIE device. Assuming that the PCIE device supports both UEFI and Legacy modes, the adjusted boot mode of the PCIE device is consistent with the boot modes supported by the PCIE device, and the UEFI mode is stored in a dynamic area of ​​the non-volatile random access memory. The PCIE device boots in UEFI mode the next time it boots.

[0114] In this embodiment, in response to determining that the adjusted startup mode of the PCIE device is consistent with the startup mode supported by the PCIE device, the PCIE device is started using the adjusted startup mode of the PCIE device the next time it is started, thereby avoiding problems such as PCIE device failure to recognize, disk drop, card drop, system loss, etc. caused by the inappropriate adjusted startup mode.

[0115] In an example embodiment, the method further includes: in response to determining that the target startup mode is inconsistent with the startup mode supported by the PCIE device, determining that the PCIE device is the target PCIE device; and displaying a prompt message in a pop-up window that the target PCIE device does not support the target startup mode.

[0116] Exemplarily, in response to determining that the boot mode of the PCIE device is adjusted to UEFI mode, a check is performed to determine whether the UEFI mode is consistent with the boot mode supported by the PCIE device. Assuming that the boot mode supported by the PCIE device is Legacy mode, if the boot mode after the PCIE device is adjusted is inconsistent with the boot mode supported by the PCIE device, the PCIE device is determined to be the target PCIE device, and a prompt message indicating that the target PCIE device does not support UEFI mode is displayed in a pop-up window.

[0117] In this embodiment, in response to determining that the adjusted startup mode of the PCIE device is inconsistent with the startup mode supported by the PCIE device, the server operation and maintenance personnel are promptly notified that the system does not support the adjusted startup mode of the PCIE device.

[0118] In an example embodiment, the method further includes: obtaining information of all downstream ports through the PCIE protocol; generating a slot information linked list of each PCIE device based on the information of all downstream ports; generating a target data structure table based on the slot information linked list of each PCIE device and the startup mode supported by each PCIE device, so that a user can export the target data structure table, and view the startup mode supported by each PCIE device based on the target data structure table.

[0119] In some embodiments, the target data structure table may be an SMBIOS (System Management BIOS) Type 9 data structure table. SMBIOS is a unified specification that motherboard or system manufacturers must follow to display product management information in a standard format. Type refers to the type.

[0120] The system obtains information about all downstream ports through the PCIE protocol. Based on this information, it generates a linked list of slot information for each PCIE device. The SMBIOS Type 9 data structure table is expanded to include additional boot modes supported by each PCIE device. Server operators can export the SMBIOS Type 9 data structure table to view the supported boot modes for each PCIE device.

[0121] In this embodiment, the target data structure table can be expanded to add additional startup modes supported by each PCIE device, so that server operation and maintenance personnel can export the target data structure table and view the startup modes supported by each PCIE device. Therefore, the startup modes supported by each PCIE device can be viewed in-band.

[0122] In an exemplary embodiment, the method further includes: sending a file in a preset format to the BMC integrated circuit through the Redfish out-of-band interface, so that the BMC integrated circuit displays the boot modes supported by each PCIE device under the device list of the BMC network interface based on the file in the preset format.

[0123] In some embodiments, a Redfish out-of-band interface is reserved, and the cJSON file is sent to the BMC integrated circuit through the Redfish out-of-band interface. The BMC integrated circuit queries the corresponding fields in the cJSON file to determine the boot mode supported by each PCIE device, and then displays the boot mode supported by each PCIE device in the device list on the BMC network interface.

[0124] Please refer to Figure 2, which is a second flow chart of a method for displaying a PCIE device startup mode provided by an embodiment of the present application. The method is applied to a BMC integrated circuit, as shown in Figure 2, and the method may include the following steps:

[0125] Step 201: Receive a file in a preset format sent by a BIOS integrated circuit; the file in the preset format is generated based on device information of each PCIE device, where the device information of the PCIE device includes a preset global variable, and the preset global variable stores an AND operation result of a first preset bit of a function list in a configuration space of the PCIE device and a second preset bit of a PCIE function bit;

[0126] Step 202: Display the boot modes supported by each PCIE device under the device list of the BMC network interface based on the file in the preset format.

[0127] In step 201, the preset global variable may be, for example, DeviceSupportBootModeValue. The global variable DeviceSupportBootModeValue is declared, and the BIOS integrated circuit assigns the result of an AND operation between the first preset bit of the function list in the configuration space of the PCIE device and the second preset bit of the PCIE function bit to the global variable DeviceSupportBootModeValue. The preset format file may be a cJSON file, and the device information of each PCIE device, including the global variable DeviceSupportBootModeValue, is created as a cJSON file. The BIOS integrated circuit sends the cJSON file to the BMC integrated circuit, which receives the cJSON file sent by the BIOS integrated circuit.

[0128] In step 202 , the BMC integrated circuit displays the boot modes supported by each PCIE device under the device list of the BMC network interface based on the cJSON file.
