[0036] Embodiment 1

[0037] Figure 1This is a flowchart of a device information acquisition method provided in the first embodiment of the present application. The present embodiment of the present application can be applied to the case of acquiring information of a target device. Typically, it can be applied to the case of acquiring information such as the temperature and power of a processor. The method can be executed by a device information acquisition device, which can be implemented in the form of hardware and / or software, and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0038] S110, obtaining target protocol information of a target protocol between a target device and a platform path controller; wherein the target protocol is a protocol adopted by the target device to communicate with the platform path controller.

[0039] Among them, the target device can be a device that can generate target information and the target information can be acquired. The target device can be a processor, and the target information can be information such as temperature and frequency. The platform path controller is a device that can connect interfaces with different data transmission rates for communication. The interface rates of the target device and the information acquisition device may be different, and they cannot be directly connected for communication. The platform path controller can be used as an intermediate device to connect target devices and information acquisition devices with different interface rates for communication. The target protocol is the protocol used for communication between the target device and the platform path controller. For example, when the target device is a processor, the target protocol is the PECI (Platform Environment Control Interface) protocol. The target protocol information may include information such as the type of the target protocol, data format, message interpretation, and event occurrence order.

[0040] Exemplarily, the target protocol information of the target protocol between the target device and the platform path controller can be obtained, so as to access the target device through the target protocol command to obtain the target information. The platform path controller can send a target protocol information acquisition request to the target device to obtain the target protocol information of the target protocol, and the platform path controller sends the target protocol request to the information acquisition device. The target protocol information can also be input by the user to the information acquisition device.

[0041] In the embodiment of the present application, the process of obtaining the target protocol information can be performed once when the target device and the platform path controller are initialized, and the acquisition process is no longer performed in the subsequent process, and only the target protocol information is applied, that is, only S120-S130 is performed. S110 can also be performed to obtain the target protocol information at a preset frequency. S110 can also be performed to obtain the target protocol information when the target information needs to be obtained.

[0042] S120, based on the data packet format corresponding to the preset channel of the preset protocol, generate an information acquisition data packet for the target device according to the target protocol information, and send the information acquisition data packet to the platform path controller based on the preset channel of the preset protocol. The preset channel of the preset protocol is a protocol channel that can transparently transmit commands of the target protocol.

[0043] The preset protocol may be a communication protocol supported by both the platform path controller and the information acquisition device, and the preset channel of the preset protocol may be a protocol channel capable of transparently transmitting commands of the target protocol. For example, the preset protocol may be an ESPI (Enhanced Serial Peripheral Interface) protocol, and the preset channel may be an OOB (Out Of Band) channel.

[0044] For example, the information acquisition structure diagram is as follows: Figure 2 As shown, the information acquisition device and the platform path controller are transmitted through a preset protocol, and a data packet for communicating with the platform path controller can be generated based on the preset protocol. The information acquisition device needs to obtain data from the target device, so there is also a command for accessing the target device based on the target protocol. The information acquisition device cannot communicate directly with the target device, so the information acquisition device generates an information acquisition data packet carrying a command of the target protocol based on the preset protocol, and sends the information acquisition data packet to the platform path controller so that the platform path controller sends the command for accessing the target device based on the target protocol to the target device. Specifically, a command of the target protocol for the target device can be generated based on the target protocol information, and the data packet format corresponding to the preset channel of the preset protocol can be used to package the data including the command of the target protocol to generate an information acquisition data packet for the target device. The information acquisition data packet is sent to the platform path controller based on the preset channel of the preset protocol.

[0045] S130 , accessing the target device according to the information acquisition data packet through the platform path controller, and acquiring target information from the target device.

[0046] Exemplarily, the information acquisition data packet is an access data packet for the target device generated according to the target protocol. The target device is accessed according to the information acquisition data packet by the platform path controller to obtain the target information in the target device, and the target information is returned to the information acquisition device, thereby achieving the acquisition of the target information of the target device. According to the above scheme, the target information of the target device is obtained. Since the preset channel of the preset protocol can transparently transmit the commands of the target protocol, the target device can be accessed by carrying the commands of the target protocol through the platform path controller, without the need for the information acquisition device to customize the functions and interfaces related to information acquisition, etc., which reduces the cost of information acquisition and can obtain the real target information from the target device itself.

[0047] Specifically, after receiving the information acquisition data packet, the platform path controller parses the information acquisition data packet, obtains the target protocol command therein, and forwards the target protocol command to the target device, so that the target device responds to the target protocol command and returns the target information. The platform path controller receives the target information returned by the target device and sends the target information to the information acquisition device. In the process of returning the target information, the target device and the platform path controller still communicate based on the target protocol, and the platform path controller and the information acquisition device still communicate based on the preset channel of the preset protocol, that is, the target device packages the target information based on the target protocol and sends it to the platform path controller. The platform path then packages the target information based on the data packet format corresponding to the preset channel of the preset protocol and sends it to the information acquisition device.

[0048] The technical solution of the embodiment of the present application is to obtain the target protocol information of the target protocol between the target device and the platform path controller; wherein the target protocol is the protocol used by the target device to communicate with the platform path controller; based on the data packet format corresponding to the preset channel of the preset protocol, an information acquisition data packet for the target device is generated according to the target protocol information, and the information acquisition data packet is sent to the platform path controller based on the preset channel of the preset protocol; wherein the preset channel of the preset protocol is a protocol channel that can transparently transmit the commands of the target protocol; the platform path controller accesses the target device according to the information acquisition data packet, and obtains the target information from the target device. The above scheme can transparently transmit the commands of the target protocol to the target device through the preset channel of the preset protocol, thereby eliminating the need for customized hardware or software to support specific interfaces or specific functions, and more conveniently obtains the target information of the target device, reduces the cost of information acquisition, and can accurately obtain the real information of the target device.

[0049] Embodiment 2

[0050] Figure 3This is a flow chart of a device information acquisition method provided in the second embodiment of the present application. The present embodiment is optimized based on the above embodiment. For solutions not described in detail in the present embodiment, please refer to the above embodiment. Figure 3 As shown, the method of the embodiment of the present application specifically includes the following steps:

[0051] S210, obtaining target protocol information of a target protocol between a target device and a platform path controller; wherein the target protocol is a protocol adopted by the target device to communicate with the platform path controller.

[0052] S220: Determine a command code of a target protocol, an access address of a target device, and an access command of the target information according to the target protocol information.

[0053] Exemplarily, the command code is an identifier representing the target protocol, the access address is a logical address for accessing the target device, and the access command is an access command for the target information. Different types of target information have different access commands. For example, when the types of target information are temperature and power, the corresponding access commands are different.

[0054] In an embodiment of the present application, the command code of the target protocol, the access address of the target device, and the access command of the target information can be determined based on the target protocol information. The information acquisition device predetermines the information required to access the target device so that the platform path controller can quickly access the target information based on the information required to access the target device.

[0055] For example, in the case where the target protocol is the PECI protocol, it can be determined according to the preset protocol that the command code representing the target protocol is 01h, and the access address of the target device is an address starting from 30h. If there is only one target device, the access address of the target device is 30h. If there are three target devices, the access address of the first target device is 30h, the access address of the second target device is 31h, and the access address of the third target device is 32h, and so on. According to the provisions of the preset protocol, if the target information to be obtained is temperature, the corresponding access command is 1h, and if the target information to be obtained is power, the corresponding access command is a1h.

[0056] S230 , based on the data packet format of the preset channel of the preset protocol, the data including the command code of the target protocol, the access address of the target device and the access command of the target information are packaged to generate an information acquisition data packet for the target device.

[0057] Exemplarily, the information acquisition device communicates with the platform path controller through a preset channel of a preset protocol, so a data packet is generated based on the data packet format of the preset channel of the preset protocol. Specifically, based on the data packet format of the preset channel of the preset protocol, data containing the command code of the target protocol, the access address of the target device, and the access command of the target information are packaged to transparently transmit the command code of the target protocol, the access address of the target device, and the access command of the target information. In addition, the information acquisition data packet also needs to include basic information such as the data packet type, the target receiving address (the receiving address of the platform path controller), and the source sending address (the sending address of the information acquisition device).

[0058] For example, when the target protocol is PECI protocol and the preset protocol is ESPI protocol, the format of the information acquisition data packet is as follows: Figure 4 As shown, eSPI Cycle Type: OOB Message = 21h indicates that the channel used by the ESPI protocol is the OOB channel, and the type of the information acquisition data packet is an OOB data packet. Dest Slave ADDR[7:1] = 10h (PCH) indicates that the target receiving address is 10h, that is, the platform path controller. Command Code = 01h (PECI Command) indicates that the command code is 01h, which is a PECI command. Source Slave ADDR[7:1] = 07h (Espi Slave0) indicates that the source sending address is 07h, that is, the information acquisition device. PECI Target Address = 30h (CPU0) indicates that the target device address to be accessed is 30h, that is, the first processor. Command = 1h (GetTemp Commend) indicates that the access command is 1h, and the target information to be accessed is temperature.

[0059] S240: Send the information acquisition data packet to the platform path controller based on a preset channel of a preset protocol.

[0060] S250: Parse the information acquisition data packet through the platform path controller to obtain a command code of a target protocol, an access address of a target device, and an access command of target information.

[0061] Exemplarily, after receiving the information acquisition data packet, the platform path controller parses the information acquisition data packet to obtain information about accessing the target device, including the command code of the target protocol, the access address of the target device, and the access command of the target information.

[0062] S260: Determine a target protocol according to the command code, send an access command for target information to an access address of a target device based on the target protocol, and obtain target information from the target device.

[0063] Exemplarily, the target protocol adopted for communication is determined according to the command code, and a target information access command is sent to the access address of the target device based on the target protocol, thereby forwarding the target information access command through the platform path controller, accessing the target device, and obtaining the target information in the target device.

[0064] In an embodiment of the present application, obtaining target information from the target device includes:

[0065] The target information returned by the target device is received by the platform path controller, and based on the data packet format of the preset channel of the preset protocol, the command code of the target protocol and the data of the target information are packaged to generate an information return data packet;

[0066] An information return data packet sent by the platform path controller is received, and the information return data packet is parsed to obtain target information.

[0067] Exemplarily, the target device packages the target information based on the target protocol and sends it to the platform path controller. The platform path controller receives the target information returned by the target device, and packages the data containing the command code of the target protocol and the target information based on the data packet format of the preset channel of the preset protocol to generate an information return data packet. In addition to the command code of the target protocol and the target information, the information return data packet also includes basic information such as the data packet type, the target receiving address (the sending address of the information acquisition device), and the source sending address (the receiving address of the platform path controller). Send an information return data packet to the information acquisition device. The information acquisition device receives the information return data packet sent by the platform path controller, and parses the information return data packet to obtain the target information.

[0068] The embodiment of the present application provides a device information acquisition method, which determines the command code of the target protocol, the access address of the target device, and the access command of the target information according to the target protocol information. Based on the data packet format of the preset channel of the preset protocol, the data containing the command code of the target protocol, the access address of the target device, and the access command of the target information are packaged to generate an information acquisition data packet for the target device, so that the commands of the target protocol required to access the target device are packaged and transparently transmitted through the preset protocol, thereby realizing access between different interfaces. The information acquisition data packet is parsed by the platform path controller to obtain the command code of the target protocol, the access address of the target device, and the access command of the target information. The target protocol is determined according to the command code, and the access command of the target information is sent to the access address of the target device based on the target protocol, and the target information is obtained from the target device, so that the access information of the target device is forwarded through the platform path controller, and access between different interface devices is realized without customizing the information acquisition device.

[0069] Embodiment 3

[0070] Figure 5 This is a flow chart of a device information acquisition method provided in the third embodiment of the present application. The present embodiment is optimized based on the above embodiment. For solutions not described in detail in the present embodiment, please refer to the above embodiment. Figure 5 As shown, the method of the embodiment of the present application specifically includes the following steps:

[0071] S310: Receive an enable status query instruction for the status register of the preset channel sent by the platform path controller, and return an enable status to the platform path controller in response to the enable status query instruction.

[0072] Exemplarily, after the target device, the platform path controller, and the information acquisition device are powered on and initialized, the platform path controller sends an enable state query instruction to the status register of the preset channel in the information acquisition device, and the information acquisition device returns the enable state to the platform path controller in response to the enable state query instruction. If the enable state returned by the information acquisition device to the platform path controller is a disabled state, when the platform path controller receives that the enable state is a disabled state, the platform path controller generates an enable state setting instruction and sends the enable state setting instruction to the information acquisition device to set the status register to an enabled state.

[0073] S320, receiving an enable state setting instruction for a status register of the preset channel sent by the platform path controller, and setting the status register to an enabled state in response to the enable state setting instruction. The enable state setting instruction is generated when the platform path controller detects that the received enable state is a disabled state.

[0074] Exemplarily, the information acquisition device receives an enable state setting instruction sent by the platform path controller, and in response to the enable state setting instruction, sets the status register to the enabled state. After sending the enable state setting instruction, the platform path controller continues to send an enable state query instruction to the information acquisition device. If the status register is not set to the enabled state, the disabled state is returned to the platform path controller, and the platform path controller waits for the status register to be set. If the status register has been set to the enabled state, the enabled state is returned to the platform path controller, and the platform path controller starts to read the target information of the target device.

[0075] S330, obtaining target protocol information of a target protocol between a target device and a platform path controller; wherein the target protocol is a protocol adopted by the target device to communicate with the platform path controller.

[0076] S340, based on the data packet format corresponding to the preset channel of the preset protocol, generate an information acquisition data packet for the target device according to the target protocol information, and send the information acquisition data packet to the platform path controller based on the preset channel of the preset protocol. The preset channel of the preset protocol is a protocol channel that can transparently transmit commands of the target protocol.

[0077] S350: Access the target device according to the information acquisition data packet through the platform path controller, and acquire target information from the target device.

[0078] In an embodiment of the present application, the method further includes:

[0079] Sending the target information to the adjustment device so that the adjustment device performs a corresponding method according to the target information to adjust the information of the target device; or,

[0080] sending the target information to a target device so that the target device controls the regulating device or processes the target information according to the target information; or

[0081] The target information is sent to a display device so that the display device displays the target information.

[0082] Exemplarily, after acquiring the target information, the information acquisition device may continue to apply the target information. For example, the target information may be sent to the adjustment device so that the adjustment device performs a corresponding method according to the target information to adjust the information of the target device, for example, Figure 6 As shown, the processor temperature can be sent to the fan system, and the fan system adjusts the wind speed according to the temperature to dissipate the heat of the processor. The target information can also be sent to other target devices so that the target devices can perform other applications according to the target information. For example, Figure 7 As shown, the information acquisition device can be connected to the BMC (Baseboard Management Controller) to send the target information to the BMC for subsequent applications, such as adjusting the fan system to dissipate heat for the processor. Figure 7 In this scheme, the BMC can communicate with the platform path controller through a conventional protocol to obtain conventional data. The target information is obtained from the information acquisition device. In this scheme, the BMC does not need to be customized. The information acquisition device can also send the target information to the display device so that the display device can display the target information.

[0083] The embodiment of the present application provides a device information acquisition method, receiving an enable state query instruction for the status register of the preset channel sent by the platform path controller, and returning the enable state to the platform path controller in response to the enable state query instruction, receiving an enable state setting instruction for the status register of the preset channel sent by the platform path controller, and setting the status register to an enabled state in response to the enable state setting instruction. The above scheme can set the enable state of the status register, so that the platform path controller and the information acquisition device can communicate through the preset channel of the preset protocol, and realize the transparent transmission of the target protocol command.

[0084] Embodiment 4

[0085] The embodiment of the present application provides a specific implementation method of a device information post-acquisition method, which is optimized based on the above embodiment. The scheme not described in detail in the embodiment of the present application can be found in the above embodiment. The method of the embodiment of the present application specifically includes the following steps: wherein, the target device is a CPU (Central Processing Unit), a PCH (Platform Controller Hub), the information acquisition device is a CPLD (Complex Programmable Logic Device), the target protocol is a PECI protocol, the preset protocol is an ESPI protocol, and the preset channel is an OOB Channel. CPLD supports the ESPI interface.

[0086] Power on the CPU, PCH, and CPLD and wait for power-on completion.

[0087] Initialize the CPU, PCH and CPLD and wait for initialization to complete.

[0088] PCH sends the Get Configuration (21h) command to address 30h (the OOB Channel status register of the CPLD) to obtain the data at address 30h. The definitions of bit0 and bit1 are as follows: Figure 8 As shown. If the bit0 of the OOB Channel status register is 0, it means that the OOB Channel is enabled. At this time, send the Set Configuration command to address 30h, set the bit0 to 1, and enable the OOB Channel status register. The board sends the Get Configuration command to address 30h again to obtain the data at address 30h. If the bit1 of the 00B Channel status register is 0, it means that the 00B Channel is not ready, and continue to wait for initialization to complete. If the bit1 of the OOB Channel status register is 1, it means that the OOB Channel has been set to the enabled state and can start reading the temperature.

[0089] CPLD sends ESPI data packets to PCH through the ESPI interface. The format of the ESPI data packet is as follows: Figure 4 As shown. The type of ESPI data packet is OOB message packet, the target receiving address is 10h (PCH), the command code is 01h (PECI command), the source sending address is 07h (ESPI Slave0 device, i.e. CPLD), the target address of PECI command is 30h (CPU0), and the command is 1h (get temperature instruction). The target address of PECI command can be 30h-33h, corresponding to CPU0-CPU3, and the corresponding address can be adjusted as needed.

[0090] After PCH receives and parses the ESPI data packet sent by CPLD, it forwards the corresponding PECI command to CPU0 to obtain the current core temperature of CPU0 and returns the EPSI data packet to CPLD. The data packet format is as follows: Fig. 9 The type of the EPSI data packet sent back is an OOB message packet, the target receiving address is 07h (ESPI Slave0 device, i.e. CPLD), the command code is 01h (PECI command), the source sending address is 10h (PCH), FCS is the CRC checksum of the relevant bits of the data packet, and TEMP is the returned temperature value. Figure 4 and Fig. 9 The other data in are general settings and will not be described in detail.
