[0004] USB (Universal Serial Bus) is a computer hardware interface standard used to realize data transmission and communication between different devices. For example, USB can realize data transmission between a computer and other devices such as a keyboard, a mouse, a printer, a camera, a USB hard disk, a U disk, etc. The emergence of USB greatly improves the expandability and convenience of computers, allowing users to easily connect and use various external devices.

[0005] USB interfaces need to be integrated in the core components of USB devices. Without hardware link support for USB ports, USB devices cannot be used. In servers, USB interfaces are a basic peripheral interface that must exist. However, some processors do not support USB integration, such as some processors that only support PCI (Peripheral Component Interconnect) protocol and memory controller without USB protocol. In this case, a PCI-to-USB chip is needed for physical expansion to enable a server product using the current processor to support USB port functions.

[0006] However, in actual application, when multiple processors are used, the number of USB ports increases exponentially, and not all ports need to be used. Therefore, USB ports need to be controlled. However, the traditional way is to close the USB controller, but the USB controller controls multiple USB ports, making it difficult to accurately control the USB ports. SUMMARY

[0089] USB is a kind of computer hardware interface standard, which is used to realize data transmission and communication between different devices, for example, USB can realize data transmission between computer and other devices, such as keyboard, mouse, printer, camera, USB hard disk and U disk, etc. The emergence of USB greatly improves the expansibility and convenience of computer, so that users can easily connect and use various external devices.

[0090] USB devices are divided into two types: Host (master device) and Device (peripheral device), Host device is responsible for controlling and transmitting data, while Device device is responsible for sending or receiving data to Host, USB devices are widely used in various electronic products, such as notebook computers, servers, mobile phones, cameras, etc.

[0091] The USB interface needs to be integrated in the core components of the USB device. If there is no hardware link to support the USB port, the USB device cannot be used. In a server, the USB interface is a basic peripheral interface that must exist. However, some processors do not support USB integration, such as some processors that only support the PCI protocol and the memory controller without the USB protocol. At this time, a PCI-to-USB chip needs to be used for physical expansion to enable the server product using the current processor to support the function of the USB port.

[0092] For example, the early Intel processor integrates the USB link on the PCH chip, and the processor chip does not have the function of integrating the USB port. The USB controller on the PCH directly controls the setting of the specific USB port, such as the function of turning on or off. If other architecture processors do not have the USB link port, the USB port is expanded through the PCI-to-USB chip. According to the data manual of the PCI-to-USB chip, the register of the USB interface is enabled or disabled to control the USB port.

[0093] However, in the actual application process, when multiple processors are used, the number of USB ports increases exponentially, and not all ports need to be used. Therefore, the USB ports need to be controlled. However, the traditional method is to turn off the USB controller, but the USB controller controls multiple USB ports, and it is difficult to accurately control the USB ports.

[0094] Therefore, in order to accurately control the use of each USB port, the embodiment of the present application provides a universal serial bus port control method.

[0095] The universal serial bus port control method provided by the embodiment of the present application is applied to a basic input and output system in a server. The server includes a plurality of universal serial bus ports. The method includes executing a first control strategy after the server is powered on and started.

[0096] Referring to FIG. 1, a step flowchart of the first control strategy provided by the embodiment of the present application is shown. The first control strategy includes the following steps:

[0097] S11: The basic input and output system obtains the current project number of the server in the driver execution environment stage.

[0098] In the actual implementation process, a server has different usage modes according to different application projects, including the usage mode of the universal serial bus port, that is, the USB port in the server. The number and position of the ports corresponding to different projects are also different. In the actual implementation process, each USB port can be labeled according to the position.

[0099] For example, project 1 can use 4 USB ports: USB port 1, USB port 2, USB port 3 and USB port 4; project 2 can use 4 USB ports: USB port 1, USB port 2, USB port 6 and USB port 8; project 3 can use 8 USB ports: USB port 1, USB port 2, USB port 6 and USB port 8.

[0100] In the basic input output system (BIOS), the driver execution environment stage refers to the next DXE stage after the PEI stage, which is used to implement the establishment of the driver environment, and the current project number of the server is obtained in the DXE stage of the BIOS.

[0101] In an available embodiment, obtaining the current project number of the server comprises:

[0102] Obtaining a state value of one or more target general input output interfaces; and searching for the current project number of the server according to the state value of the one or more target general input output interfaces in a preset project number configuration table.

[0103] The project number configuration table contains the state value of one or more target general input output interfaces corresponding to each project number.

[0104] The project number configuration table can be stored in the BIOS in advance, and the project number configuration table contains the state value of one or more target general input output interfaces corresponding to each project number. In the actual implementation process, the number of target general input output interfaces of the project number can be customized according to the actual application requirements. For example, it is assumed that the project number of the server can be determined by the combination of the state values of 3 GPIO interfaces: GPIO0, GPIO01 and GPIO02, and the project number configuration table can be as shown in Table 1.

[0105] Table 1 Project number configuration table

[0106] In the DXE stage of the BIOS, the BIOS obtains the state values of GPIO0, GPIO01 and GPIO02, and the project number of the server can be determined according to the combination of the state values of GPIO0, GPIO01 and GPIO02. For example, the combination of the state values of GPIO0, GPIO01 and GPIO02 is 011, and the current project number corresponding to 011 in the project number configuration table is project 4.

[0107] In another available embodiment, when obtaining the current project number of the server, the BIOS can obtain part number information in the information of the field replaceable unit; determine the current project number of the server according to the value of the part number information; and the value of the part number information and the project number are one-to-one corresponding.

[0108] Specifically, the part number information (PPN information) in the field replaceable unit (FRU) information can be updated by the BMC in the server, and a corresponding relationship between the PPN information and the project number can be established. For example, the corresponding relationship between the PPN information and the project number can be: PPN=1 corresponds to project 1, PPN=2 corresponds to project 2, and PPN=N corresponds to project N.

[0109] In the DXE stage of the BIOS, the BIOS acquires the PPN information in the FRU information through the IPMI protocol, and according to the value of the PPN information, the current project number can be determined. For example, if PPN=1 is read, the current project number is project 1.

[0110] In other embodiments, other ways can also be used to acquire the current project number of the server. For example, an option for setting the current project number can be provided on the interface of the BIOS, and the current project number of the server can be determined in response to a selection operation of a user on the option for setting the current project number on the interface of the BIOS.

[0111] S12: According to the current project number, determine the target universal serial bus port configuration information corresponding to the current project number.

[0112] In a feasible embodiment, a region block can be created in the BIOS in advance, and then a project number port configuration table can be stored in the region block. The project number port configuration table stores the USB port configuration information corresponding to each project number.

[0113] Specifically, in response to a first configuration operation, a region block is created in the BIOS; in response to a second configuration operation, the USB port configuration information corresponding to each project number is acquired; according to the USB port configuration information corresponding to each project number, a project number port configuration table is created, and the project number port configuration table is stored in the region block.

[0114] Then, when determining the target USB port configuration information corresponding to the current project number according to the current project number, the target USB port configuration information corresponding to the current project number is searched for in the project number port configuration table stored in the region block of the BIOS according to the current project number.

[0115] For example, the USB port configuration information corresponding to each project number included in the project number port configuration table can only include the number of enabled USB ports, and the project number port configuration table is shown in Table 2.

[0116] Table 2 Project number port configuration table

[0117] For example, the USB port configuration information corresponding to each item number in the item number port configuration table can also include the number of enabled USB ports and the USB port position and the USB port position. The item number port configuration table is shown in Table 3.

[0118] Table 3 Item number port configuration table

[0119] When the USB port configuration information only includes the number of enabled USB ports, the BIOS can configure the corresponding number of USB ports to be in the enabled state according to the number of USB ports required by the item number. When the USB port configuration information includes the number of enabled USB ports and the USB port position and the USB port position, the corresponding USB port is set to the enabled state according to the USB port position.

[0120] S13: Generate a port configuration table corresponding to the current item number according to the target universal serial bus port configuration information.

[0121] Specifically, according to the target USB port configuration information, set the configuration information corresponding to each of the plurality of USB ports in the first port configuration mode and the second port configuration mode in the default port configuration table in the BIOS, and generate a port configuration table corresponding to the current item number. Specifically, the port configuration table can be an ACPI table, and the ACPI table is used to manage the configuration of all USB ports of the server.

[0122] The USB port setting includes a first port configuration mode, such as a UPC mode, and a second port configuration mode, such as a PLD mode. The UPC mode includes two variables: a first variable and a second variable. The first variable is used to define whether the USB port is connected, and the second variable is used to define the supported USB device type.

[0123] In the process of setting the configuration information corresponding to each of the plurality of USB ports in the UPC mode in the default ACPI table in the BIOS, in the UPC mode of the default ACPI table, set the first variable according to whether any USB port is the target port corresponding to the current item number, and set the second variable according to the universal serial bus protocol, i.e., the USB protocol type, supported by any USB port.

[0124] For example, when any USB port is the target port corresponding to the current item number, the value of the first variable is set to 0xFF, indicating that the USB port is connected and can be used, i.e., the USB port is configured to be in the enabled state. When any USB port is not the target port corresponding to the current item number, the value of the first variable is set to 0x00, indicating that the USB port is not connected, i.e., cannot be used, i.e., the USB port is configured to be in the closed state.

[0125] When any one of the USB ports only supports USB 2.0 devices, the value of the second variable is set to 0x00; when any one of the USB ports only supports USB 3.0 devices, the value of the second variable is set to 0x03.

[0126] Two variables are also included in the PLD mode: a third variable and a fourth variable, the third variable is used to define whether the USB port device is visible, and the fourth variable is used to define the universal serial bus device group to which the device connected by the port belongs.

[0127] In the process of setting the plurality of USB ports in the default ACPI table in the BIOS to the respective configuration information corresponding to the PLD mode respectively, in the PLD mode of the default ACPI table, the third variable is set according to whether any one of the USB ports is the target port corresponding to the current item number, and the fourth variable is set according to the universal serial bus protocol type supported by any one of the USB ports.

[0128] For example, when any one of the USB ports is the target port corresponding to the current item number, the value of the third variable is set to 0x01, indicating that the USB port is visible, i.e., can be recognized; when any one of the USB ports is not the target port corresponding to the current item number, the value of the third variable is set to 0x00, indicating that the USB port is not visible, i.e., cannot be recognized.

[0129] In actual implementation, the first variable and the third variable have a corresponding relationship, specifically, after the value of the first variable is set in the UPC mode, in the PLD mode, the value of the third variable can be determined according to the value of the first variable; that is, when the value of the first variable is 0xFF, indicating that the USB port has been connected and can be used, the value of the third variable is 0x01, indicating that the USB port is visible; when the value of the first variable is 0x00, indicating that the USB port has not been connected, i.e., cannot be used, the value of the third variable is 0x00, indicating that the USB port is not visible.

[0130] When the USB protocol type supported by any one of the USB ports is USB 2.0, the value of the fourth variable is set to 0x00, indicating that the universal serial bus device group to which the device connected by the USB port belongs is the USB 2.0 group; when the USB protocol type supported by any one of the USB ports is USB 3.0, the value of the fourth variable is set to 0x01, indicating that the universal serial bus device group to which the device connected by the USB port belongs is the USB 3.0 group.

[0131] In actual implementation, the second variable and the fourth variable have a corresponding relationship, specifically, after the value of the second variable is set in the UPC mode, in the PLD mode, the value of the fourth variable can be determined according to the value of the second variable.

[0132] For example, when any USB port only supports a USB 2.0 device, the value of the second variable is set as 0x00, and the value of the fourth variable is 0x00, indicating that the USB port connected device belongs to the USB 2.0 group; when any USB port only supports a USB 3.0 device, the value of the second variable is set as 0x03, and the value of the fourth variable is 0x01, indicating that the USB port connected device belongs to the USB 3.0 group.

[0133] The plurality of USB ports are respectively set with corresponding configuration information in the default ACPI table in the BIOS in the UPC mode and the PLD mode, so as to generate the ACPI table corresponding to the current project number as the port configuration table.

[0134] S14: uninstall the default port configuration table in the basic input and output system, and load the port configuration table corresponding to the current project number, so that the operating system of the server can control the plurality of universal serial bus ports after the operating system is started.

[0135] The default port configuration table loaded in the BIOS is uninstalled, and then the port configuration table corresponding to the current project number is loaded, so that the operating system (OS) can automatically call the port configuration table corresponding to the current project number, and then control the plurality of USB ports according to the port configuration table corresponding to the current project number, thereby realizing accurate control of the plurality of USB ports.

[0136] Referring to FIG. 2, a swim lane diagram of the first control strategy provided by the embodiment of the application is shown. In the first control strategy, after the server is powered on, the basic input and output system (BIOS) obtains the current project number in the driver execution environment stage, and then the BIOS determines the target universal serial bus port configuration information corresponding to the current project number according to the current project number.

[0137] Then, in the default port configuration table (default ACPI table) of the BIOS, the configuration information corresponding to any USB port in the first port configuration mode is set, and the first variable is set according to whether any port is the target port corresponding to the current project number, and then the second variable is set according to the universal serial bus protocol (USB protocol type) supported by any port.

[0138] Specifically, when any one of the USB ports is the target port corresponding to the current item number, the value of the first variable is 0xFF, indicating that the USB port is connected and available; when any one of the USB ports is not the target port corresponding to the current item number, the value of the first variable is 0x00, indicating that the USB port is not connected and unavailable; when any one of the USB ports only supports a USB 2.0 device, the value of the second variable is 0x00; when any one of the USB ports only supports a USB 3.0 device, the value of the second variable is 0x03.

[0139] In the default port configuration table of the BIOS, configuration information corresponding to any USB port in the second port configuration mode is set, and a third variable is set according to whether any port is the target port corresponding to the current item number; a fourth variable is set according to the type of the universal serial bus protocol supported by any port.

[0140] Specifically, when any one of the USB ports is the target port corresponding to the current item number, the value of the third variable is 0x01, indicating that the USB port is visible; when any one of the USB ports is not the target port corresponding to the current item number, the value of the third variable is 0x00, indicating that the USB port is invisible; when the USB protocol type supported by any USB port is USB 2.0, the value of the fourth variable is 0x00, indicating that the universal serial bus device group to which the device connected by the USB port belongs is the USB 2.0 group; when the USB protocol type supported by any USB port is USB 3.0, the value of the fourth variable is 0x01, indicating that the universal serial bus device group to which the device connected by the USB port belongs is the USB 3.0 group; and the first variable and the third variable have a corresponding relationship, and the second variable and the fourth variable have a corresponding relationship.

[0141] Finally, the BIOS unloads the default port configuration table and loads the port configuration table corresponding to the current item number.

[0142] In addition to the precise control of the plurality of USB ports in the server through the first control strategy, an input-output control chip, i.e., a GPIO control chip, can also be set in the server, each pin of the GPIO control chip is connected to a power control signal of a USB port, and then the second control strategy is executed when a target event is monitored.

[0143] Referring to FIG. 3, a step flowchart of the second control strategy provided by the embodiment of the application is shown, and the second control strategy includes the following steps:

[0144] S21: In response to a selection operation of a user on a universal serial bus port configuration option in a basic input-output system interface, control information of any universal serial bus port is obtained.

[0145] The USB port configuration option is added on the interface of the BIOS, and the user can configure the control information of any USB port on the USB port configuration option on the interface of the BIOS, so as to determine the enabled state or closed state of the USB port.

[0146] S22: According to the control information of any universal serial bus port, the output state of the pin connected to the universal serial bus port on the input and output control chip is controlled to control the power control signal of the universal serial bus port.

[0147] Specifically, when the control information of any USB port is enabled, the output state of the pin connected to the USB port on the GPIO control chip is high; when the control information of any USB port is closed, the output state of the pin connected to the USB port on the GPIO control chip is low.

[0148] Specifically, the BIOS can control the output state of any pin of the GPIO control chip based on the I2C protocol, when the BIOS controls the output state of the pin connected to the USB port on the GPIO control chip to be high, the power control signal of the USB port is powered, when the BIOS controls the output state of the pin connected to the USB port on the GPIO control chip to be low, the power control signal of the USB port is not powered, after the BIOS sets up each pin connected to the USB port on the GPIO control chip, the BIOS enables the output state of the pin of the GPIO through I2C and starts normally, thereby completing the accurate control of each USB port.

[0149] In a possible implementation, the target event can be whether the BIOS acquires the current project number of the server within a first preset time period, when it is monitored that the BIOS does not acquire the current project number of the server within the first preset time period, the second control strategy is executed; when it is monitored that the BIOS acquires the current project number of the server within the first preset time period, the first control strategy can be executed.

[0150] In a possible implementation, the target event can also be whether the BIOS generates the port configuration table corresponding to the current project number within a second preset time period, when it is monitored that the BIOS does not generate the port configuration table corresponding to the current project number within the second preset time period, the second control strategy is executed; when it is monitored that the BIOS generates the port configuration table corresponding to the current project number within the second preset time period, the first control strategy can be continued to be executed.

[0151] The time length of the second preset time period is greater than the time length of the first preset time period.

[0152] In an implementable embodiment, the target event can also be monitoring whether the user operates the USB port configuration option on the BIOS interface, when it is monitored that the user selects the USB port configuration option on the BIOS interface, the second control strategy is executed; when it is not monitored that the user selects the USB port configuration option on the BIOS interface, the second control strategy is continuously executed.

[0153] In addition, the user can also autonomously select to adopt the first control strategy or the second control strategy to accurately control the plurality of USB ports, specifically, when it is monitored that the user selects the USB port configuration strategy on the BIOS interface, it is determined to execute the first control strategy or the second control strategy.

[0154] Referring to FIG. 4, a swim lane diagram of the second control strategy provided by the embodiments of the present application is shown. After the server is powered on, the basic input output system acquires the control information of any universal serial bus port in response to the selection operation of the user on the universal serial bus port configuration option of the basic input output system interface; it is judged whether the control information of any universal serial bus port is enabled; when the control information of any universal serial bus port is not enabled, the output state of the pin connected to the universal serial bus port on the input output control chip is controlled to be high; when the control information of any universal serial bus port is closed, the output state of the pin connected to the universal serial bus port on the input output control chip is controlled to be low; it is judged whether the control information of all universal serial bus ports is executed, when not all control information of the universal serial bus ports is executed, the control information of the next universal serial bus port is continuously judged; after all control information of the universal serial bus ports is executed, the basic input output system enables the output state of the pin of the input output control chip through I2C and normally starts; the basic input output system continues to start.

[0155] The method adopts two USB control strategies to accurately control the USB port, one is that the BIOS determines the target USB port configuration information required by the current project number according to the obtained current project number, sets the first port configuration mode and the second port configuration mode of any USB port in the default port configuration table, including setting whether any port is connected, support type, whether visible, and USB device grouping and other information, and the BIOS controls the USB port by unloading the default port configuration table and loading the port configuration table corresponding to the current project number; the other is to introduce a GPIO control chip in the hardware, physically link the GPIO control chip pin and the power supply signal of the USB port, and add USB port configuration options on the interface of the BIOS, and enable or close the control information set by the BIOS, set the output state of the GPIO control chip to high or low level through the I2C protocol, and high level represents that the USB port is enabled, and low represents that the USB port is closed, so as to realize the control opening and closing function of the specific USB port. The method can not only accurately control the enablement or closing of the USB port, but also can be applied to any architecture server, and has high applicability.
