Detailed Description

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

First, terms related to embodiments of the present application will be described.

Unified Extensible Firmware Interface (UEFI): a computer system specification defines a software interface between an operating system and system firmware.

Baseboard Management Controller (BMC): the remote management controller of the server is executed, and the remote management controller can realize the operations of upgrading the firmware of the machine, checking the equipment of the machine and the like under the state that the machine is not started.

Platform Controller Hub (PCH): and an integrated south bridge.

In-band management: it means that the management control information of the network and the bearer information of the user network are transmitted through the same logical channel.

Managing outside the band: it means that the management control information of the network and the bearer information of the user network are transmitted in different logical channels.

B1OS Setup function (Setup): key configuration parameters and system settings of the BIOS are saved.

The BIOS setting method and the BIOS chip provided in the embodiment of the present application may be applied to various types of computer devices, which is not limited in this embodiment of the present application, and may be applied to, for example, a personal computer, a server, and the like.

The server is taken as an example for explanation. Fig. 1 is a schematic diagram of a server architecture. As shown in fig. 1, the server includes a Central Processing Unit (CPU) 0 and a CPU1, where the CPU0 and the CPU1 are connected to a Double Data Rate Dynamic Random Access Memory (DDR SDRAM) through an Integrated Memory Controller (IMC). CPU0 and PCH are connected via a Direct Media Interface (DMI). The PCH may be connected to a hard disk through a Serial Advanced Technology Attachment (SATA) interface, the PCH may be connected to an external device through a Universal Serial Bus (USB) interface, and the BMC may be connected to the external device through a Serial interface. A Peripheral Component Interconnect Express (PCIE) interface may be provided between the PCH and the BMC. The PCH and the BMC are connected to a BIOS chip, which may be an SPI FLASH chip, through a Serial Peripheral Interface (SPI) and a data selector (MUX).

The setting function of the BIOS can realize the modification of the BIOS setting items, and the modification comprises two parts of contents, wherein one part is to modify the BIOS setting items, and the other part is to enable the modified BIOS setting items to take effect.

In relation to the first point, the BIOS setup function generally provides a human-machine interface through which a user can modify setup items of the BIOS, and the modified result will be stored in a Variable area of the BIOS storage, and an example, as shown in fig. 2, is a schematic diagram of the BIOS storage, in which a Descriptor (Descriptor) and a Management Engine (ME) in the BIOS are illustrated in addition to the Variable area illustrating the BIOS storage. It should be noted that fig. 2 is only an example and is not limited thereto. However, for a running server, if the running server wants to enter the human-computer interaction interface, the server needs to be restarted, and the running server enters the human-computer interaction interface set by the BIOS through a shortcut key or the like in the restarting process.

In addition to the above human-computer interface, some out-of-band BMC or in-band Operating System (OS) tools may also modify BIOS setting items, that is, modify a Variable area stored in the BIOS, some of these tools may directly modify the Variable area stored in the BIOS, and some tools may need to restart the server, and modify the Variable area stored in the BIOS during the restart process.

Regarding the second point, the validation of the BIOS setting item is usually performed by reading a value of the setting item from the Variable area during the boot process of the BIOS, and modifying a register corresponding to the setting item to validate the setting item, where the register may be a register in the CPU, the PCH or the peripheral chip, that is, the validation of the BIOS setting item, that is, the modification of the register, also requires the server to be restarted.

It can be seen from the above two points that, when the setting item of the BIOS is modified, that is, when the Variable area stored in the BIOS is modified, a reboot may be required on the server, and when the setting item of the BIOS is validated, a reboot is inevitably required, which results in at least one reboot in the whole process, and even multiple reboots, and for the server in operation, this inevitably causes an application running on the server to be interrupted.

In view of the above two contents of modification and validation of the BIOS setting items, a core problem is that in the current scheme, validation of the BIOS setting items, that is, modification of registers, is implemented in the boot process, that is, a server needs to be restarted, and the root cause of this problem is that modification of registers of many chips needs to be restarted to be validated due to the history of technical development, but at present, many registers can be modified and validated in real time with the development of technology. In some scenarios, it may be considered to modify the register values directly in a hardware-driven manner, but this scheme is only effective once, and after the server is restarted, the register values are overwritten by the values set in the BIOS.

In view of this, the embodiment of the present application provides a BIOS setting method, considering a register that can be modified in real time, in which an external functional interface is provided to implement BIOS setting, a user can call the interface to set a BIOS, and based on interface information, the BIOS modifies a Variable area and also modifies a corresponding register, so that modified setting items take effect in real time, thereby implementing real-time and permanent modification and effect of BIOS setting items, and the entire process does not involve restarting a server and does not generate interrupt influence on applications running on the server.

The following describes a BIOS setting method according to an embodiment of the present application in detail with reference to the accompanying drawings.

Fig. 3 is a schematic flowchart of a BIOS setting method according to an embodiment of the present disclosure. The execution main body of the embodiment of the application is a BIOS chip. As shown in fig. 3, the BIOS setting method includes:

s301, receiving BIOS setting information through the BIOS setting interface, wherein the BIOS setting information comprises target values of the target setting items.

The BIOS setting interface in the embodiment of the present application is an interface provided by a BIOS chip and available for external invocation, and a user may transfer BIOS setting information to the BIOS by invoking the BIOS setting interface, where the BIOS setting information includes a target setting item to be set, that is, a target setting item to be modified, and a target value corresponding to the target setting item. The target setting item may be any BIOS setting item that is modifiable provided by a setting function of the BIOS, and the target value is any of values that the BIOS setting item can set.

For example, the target setting items may include system status setting items such as system date, time, various hardware information, and the like; the target setting items can comprise setting items such as PCI subsystems, various chip sets in a mainboard, power management, computer hardware monitoring, external operation equipment control and the like; the target setting items can comprise hardware frequency and voltage, including setting items such as CPU frequency, memory frequency, CPU voltage, memory voltage, PCI voltage and the like; the target setting items can comprise system security passwords, including setting items such as administrator passwords, user passwords, case intrusion setting and the like; the target setting items can include starting information of the system, including setting items such as starting configuration, starting mode and setting starting sequence.

S302, storing the target value of the target setting item to a variable area stored by the BIOS, and modifying the value of a register corresponding to the target setting item into the target value of the target setting item so as to enable the target value of the target setting item to take effect.

In the embodiment of the application, the BIOS chip receives BIOS setting information through the BIOS setting interface, modifies a Variable region, that is, a Variable region, stored in the BIOS, and modifies a value of a target setting item stored in the Variable region to a target value, that is, modification of the target setting item is achieved, and the BIOS chip also directly modifies a register corresponding to the target setting item, that is, modifies a value of the target setting item stored in the register to a target value, that is, achieves real-time validation of the target value of the target setting item.

In the method for setting the BIOS provided in the embodiment of the present application, the BIOS is set through an external BIOS setting interface, a user can set the BIOS by calling the interface, and the BIOS modifies a Variable area storing setting items and a corresponding register based on interface information, so that the modified setting items take effect in real time, thereby modifying and taking effect of the real-time BIOS setting items.

On the basis of the above embodiments, the BIOS setting interface provided in the embodiment of the present application is described with reference to the architecture shown in fig. 4. As shown in fig. 4, the BIOS is located between hardware and an operating system of the computer, and includes a UEFI Framework (Framework), an Independent BIOS Vendor (IBV) service, an Original Equipment Manufacturer (OEM) Common Features (Common Features), a UEFI OS Loader (Loader), a Legacy Compatible Support Module (CSM), and a BIOS setup interface.

Optionally, the BIOS setting interface may be an interface called by an operating system, for example, as illustrated in fig. 4, the BIOS setting interface is called by the operating system, that is, BIOS setting is performed in an in-band management manner.

Optionally, the BIOS setting interface may be an interface called by the BMC, for example, as illustrated in fig. 4, the BIOS setting interface is called by the BMC, that is, the BIOS setting is performed in an out-of-band management manner.

It is understood that whether the BIOS setup interface is called by the operating system or the BMC, the BIOS directly modifies the variable region in the BIOS storage and modifies the registers in the hardware, which is also illustrated in fig. 4.

On the basis of the above embodiments, in order to ensure the security of the BIOS setting, a security authentication mechanism is further provided in the BIOS setting method according to the embodiment of the present application.

Optionally, the security authentication performed by the user and the sending of the BIOS setting information may be synchronized, when the user calls the BIOS setting interface through the operating system or the BMC, the BIOS setting information may include an identity verification information in addition to the target value of the target setting item, and accordingly, after receiving the BIOS setting information, the BIOS may perform identity verification through the identity verification information, that is, perform identity verification on the BIOS setting information based on the identity verification information; and if the identity authentication is passed, storing the target value of the target setting item to a variable area stored by the BIOS, and modifying the value of a register corresponding to the target setting item into the target value of the target setting item so as to enable the target value of the target setting item to take effect.

For example, the authentication information may be signature information generated according to a private key of the user, after the BIOS receives the BIOS setting information, the public key of the user may be used to verify the signature information in the BIOS setting information, if the verification passes, the subsequent modification of the BIOS setting item is continued, and if the verification fails, the modification of the BIOS setting item is not performed.

For example, the authentication information may be a user name and a password, after the BIOS receives the BIOS setting information, the BIOS may perform authentication using the user name and the password, if the authentication passes, continue to perform subsequent modification on the BIOS setting item, and if the authentication fails, not modify the BIOS setting item.

Optionally, the user may perform security authentication and send the BIOS setting information asynchronously, that is, perform security authentication first, and send the BIOS setting information after the security authentication passes. That is, before receiving the BIOS setting information through the BIOS setting interface, the BIOS first receives an authentication request through the BIOS setting interface; and if the identity authentication is passed, returning an identity authentication passing response through the BIOS setting interface.

For example, the identity authentication request may include signature information generated according to a private key of the user, after receiving the identity authentication request, the BIOS may check and sign the signature information in the identity authentication request using a public key of the user, if the authentication passes, return an authentication passing response through the BIOS setting interface, so that the user continues to send the BIOS setting information through the BIOS setting interface, and if the authentication fails, return an authentication failure response, so that the user cannot continue to send the BIOS setting information through the BIOS setting interface.

For example, the authentication request may include a user name and a password, after receiving the authentication request, the BIOS may perform authentication using the user name and the password, and if the authentication passes, return an authentication passing response through the BIOS setting interface, so that the user continues to send the BIOS setting information through the BIOS setting interface, and if the authentication fails, return an authentication failure response, so that the user cannot continue to send the BIOS setting information through the BIOS setting interface.

This is illustrated with reference to fig. 4. Illustratively, a user calls a BIOS setting interface through BMC, BIOS setting information is transmitted to the BIOS, the BIOS setting information comprises a target value of a target setting item, meanwhile, the user also adopts a summary algorithm to generate a summary of the target value of the target setting item, and adopts a private key to sign the summary, and the signature is carried in the BIOS setting information.

After receiving the BIOS setting information through the BIOS setting interface, the BIOS checks the signature carried in the BIOS setting information by adopting a public key of a user, if the signature passes, namely the identity verification passes, a Variable area, namely a Variable area, stored in the BIOS is modified, the value of a target setting item stored in the Variable area is modified into a target value, a register corresponding to the target setting item is modified, namely the value of the target setting item stored in the register is modified into the target value, so that the target value of the target setting item is effective in real time, and the BIOS setting is completed.

In an example, a user calls a BIOS setting interface through an operating system, and sends an identity authentication request to a BIOS, where the identity authentication request carries a user name and a password, and the BIOS verifies the user name and the password after receiving the identity authentication request through the BIOS setting interface, and returns an identity authentication pass response to the user when the verification passes. And the user transmits BIOS setting information again through the BIOS setting interface, wherein the BIOS setting information comprises the target value of the target setting item.

After receiving the BIOS setting information through the BIOS setting interface, the BIOS modifies a Variable region, that is, a Variable region, stored in the BIOS, modifies a value of a target setting item stored in the Variable region to a target value, and modifies a register corresponding to the target setting item, that is, modifies the value of the target setting item stored in the register to the target value, so that the target value of the target setting item is validated in real time, and the BIOS setting is completed this time.

Optionally, on the basis of the foregoing embodiment, in order to ensure that the setting of the BIOS is traceable, the setting method of the BIOS according to the embodiment of the present application further includes: and storing a modification record of the target setting item, wherein the modification record comprises a user calling the BIOS setting interface, time and a target value of the target setting item. It should be noted that the modification record may be stored in the BIOS storage, or may be stored in the storage of other modules, which is not limited in the embodiment of the present application.
