Detailed Description
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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 invention.
The first embodiment is as follows:
referring to fig. 1, fig. 1 is a flowchart of an implementation of an interface initialization method according to an embodiment of the present invention, where the method may include the following steps:
s101: the current GPIO value is read during startup.
The corresponding relation between the GPIO value in the mainboard and the interface type of the external trusted platform module can be preset, and after the user selects the interface type of the external trusted platform module, the system can automatically and correspondingly set the GPIO value in the mainboard according to the selected interface type. The BIOS may read the current GPIO value during start-up. The GPIO value may be set to 0 or 1, for example, 0 indicates that the trusted platform module interface type is the LPC interface type, and 1 indicates that the trusted platform module interface type is the SPI interface type.
LPC (Low Pin Count, few Pin type interface) is a decoding mode of separating and decoding the address/data of the conventional ISA BUS, which is similar to the sharing of PCI address/data signal lines, the number of the signal lines is greatly reduced, the working speed is synchronously driven by the PCI BUS speed, the number of required signal pins is greatly reduced while a larger transmission speed is maintained, for example, a SuperI/O chip and a Flash chip which are designed by the LPC interface can share the advantages of reduced Pin number and miniature volume, and the design of a main board can be simplified.
SPI (Serial Peripheral Interface) is a synchronous Serial Peripheral Interface that allows the MCU to communicate with various peripherals in a Serial manner to exchange information. The SPI bus can be directly connected with various standard peripheral devices produced by various manufacturers, including FLASHRAM, network controller, LCD display driver, A/D converter and MCU. The interface typically uses 4 wires: serial Clock Line (SCLK), master input/slave output data line MISO, master output/slave input data line MOSI, and active low slave select line NSS.
S102: and searching a target interface type corresponding to the GPIO value from the GPIO value and interface type comparison table.
A GPIO value and interface type comparison table may be preset, and when the current GPIO value in the motherboard is read during the BIOS startup process, a target interface type corresponding to the GPIO value may be searched from the GPIO value and interface type comparison table. Therefore, what interface type the trusted platform module interface in the management engine needs to be initialized currently can be obtained, and preparation is made for subsequently calling configuration information for initializing the trusted platform module interface in the management engine from the configuration information base.
S103: and calling target configuration information corresponding to the target interface type from the configuration information base.
A configuration information base can be preset, and the configuration information in the configuration information base and the interface type of the trusted platform module are stored correspondingly, for example, the LPC interface type is correspondingly provided with corresponding configuration information, and the SPI interface type is correspondingly provided with corresponding configuration information. After the target interface type corresponding to the read GPIO value is obtained by searching the GPIO value and the interface type comparison table, target configuration information corresponding to the target interface type can be called from the configuration information base. If the target interface type is determined to be the LPC interface type, the configuration information corresponding to the LPC interface type can be directly called from the configuration information base, and if the target interface type is determined to be the SPI interface type, the configuration information corresponding to the SPI interface type can be directly called from the configuration information base, the BIOS file is not required to be manually modified by software personnel, and time and labor are saved.
S104: and initializing a trusted platform module interface in the management engine to be an interface of a target interface type by using the target configuration information.
After target configuration information corresponding to the type of the target interface is obtained from the configuration information base, the trusted platform module interface in the management engine can be initialized to be the interface of the type of the target interface by using the obtained target configuration information, so that the trusted platform module interface in the management engine can be set to be the same as the interface type of an external trusted platform module interface, the trusted platform module can be normally used, the server system of a user is effectively protected by using the trusted platform module, and the tampering and illegal access of the system data of the user are prevented. When the interface types of the trusted platform modules selected by the user are different, the system can automatically set the GPIO value in the mainboard, so that the trusted platform modules with different interface types can be supported by one BIOS file for the same machine, automatic switching can be performed according to the interface types of the external trusted platform modules selected by the user, additional change is not needed, the time and labor investment for software personnel to modify, develop and release the BISO version are greatly reduced, the convenience of testing is improved, the cost for managing and controlling the BIOS version and software research and development is reduced, the multiplexing of software is improved, and the management and switching of the user are facilitated.
By the method provided by the embodiment of the invention, the GPIO value and the interface type comparison table are preset, the configuration information base corresponding to the interface type and the configuration information is set, the current GPIO value is read in the BIOS starting process, the target interface type is determined according to the current GPIO value, the corresponding target configuration information is called from the configuration information base, and the trusted platform module interface in the management engine is initialized to the interface of the target interface type by using the called configuration information. Therefore, manual operations such as BIOS file modification are not needed, dynamic initialization can be performed on the trusted platform module interface according to the current requirements of the user on the type of the trusted platform module interface, time and labor input of software personnel for modifying, developing and releasing BIOS versions are reduced, and cost is reduced.
It should be noted that, based on the first embodiment, the embodiment of the present invention further provides a corresponding improvement scheme. In the following embodiments, the same steps or corresponding steps as those in the first embodiment may be referred to each other, and the corresponding beneficial effects may also be referred to each other, which are not described in detail in the following modified embodiments.
Example two:
referring to fig. 2, fig. 2 is a flowchart of another implementation of the interface initialization method according to the embodiment of the present invention, where the method may include the following steps:
s201: the current GPIO value is read during startup.
S202: and detecting whether the GPIO value corresponds to the interface type of the selected external trusted platform module, if not, continuing to execute the step S203, and if so, skipping the step S203 and executing the step S204.
The BIOS reads a current GPIO value in the starting process, can acquire the interface type of the external trusted platform module selected by a current user, can detect whether the read GPIO value corresponds to the interface type of the selected external trusted platform module or not by acquiring the interface type of the external trusted platform module selected by the current user, and if the read GPIO value corresponds to the acquired interface type of the external trusted platform module, the system automatically sets the GPIO value in the mainboard normally according to the interface type of the external trusted platform module selected by the user, and can continue to execute the step S204 according to the read GPIO value. If the read GPIO value does not correspond to the acquired interface type of the external trusted platform module, it indicates that the system has an abnormal function of automatically setting the GPIO value in the motherboard according to the interface type of the external trusted platform module selected by the user, and if the automatic setting of the GPIO value in the previous stage fails due to a network failure, the step in step S203 may be continuously performed.
S203: and searching a GPIO value corresponding to the interface type of the selected external trusted platform module from the GPIO value and interface type comparison table, and replacing the original GPIO value in the mainboard with the searched GPIO value.
When the read GPIO value is detected not to correspond to the interface type of the selected external trusted platform module, the GPIO value corresponding to the interface type of the selected external trusted platform module can be searched from the GPIO value and interface type comparison table, and the original GPIO value in the main board is replaced by the searched GPIO value, so that the GPIO value in the main board is reset until the GPIO value is set to be the value corresponding to the interface type of the external trusted platform module, and the effectiveness of initializing the interface of the trusted platform module in the management engine in the later period is ensured.
S204: and searching a target interface type corresponding to the GPIO value from the GPIO value and interface type comparison table.
S205: and calling target configuration information corresponding to the target interface type from the configuration information base.
S206: and initializing the trusted platform module interface in the management engine to be an interface of a target interface type by using the target configuration information.
S207: and judging whether an interface type change instruction is received, if so, repeatedly executing the step S201, and if not, executing the step S208.
After initializing the trusted platform module interface in the management engine to the interface of the target interface type by using the target configuration information, determining whether an interface type change instruction is received, if so, repeatedly executing the step of reading the current GPIO value in the starting process in step S201, thereby ensuring that the trusted platform module interface in the management engine is the same as the interface type of the external trusted platform module interface, and dynamically switching the trusted platform module interface in the management engine according to the interface type of the external trusted platform module interface currently required by the user.
S208: and checking the interface type of the trusted platform module interface in the management engine obtained by initialization.
After the trusted platform module interface in the management engine is initialized to the interface of the target interface type, the interface type of the trusted platform module interface in the management engine obtained through initialization may be checked. If the interface type of the external trusted platform module interface and the interface type of the trusted platform module interface in the management engine can be obtained again, if the two interfaces are the same in type, the trusted platform module interface in the management engine is successfully initialized, otherwise, the trusted platform module interface in the management engine needs to be re-initialized. The trusted platform module interface in the management engine is further ensured to be the same as the interface type of the external trusted platform module interface, and the trusted platform module is ensured to effectively and safely protect the user server system.
