[0071] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other examples obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0072] At present, the host BIOS and CPLD can perform VGPIO communication. Since there are a large number of VGPIOs between the two, when a problem occurs, it is necessary to troubleshoot the VGPIO with the problem and locate the cause of the problem. The VGPIO communication failure may be a problem on the host side or on the CPLD side, and it is difficult to locate the location where the communication is blocked. To this end, the present application provides a communication status detection scheme that helps to locate the VGPIO communication anomaly between the host BIOS and the CPLD.

[0073] See also Figure 1 As shown, the embodiment of the present application discloses a communication status detection method, which is applied to a basic input and output system, including:

[0074] S101 . During the startup of a basic input / output system, preset channel configuration information is loaded.

[0075] It should be noted that the preset channel configuration information is pre-stored in the host side, in a memory area for the basic input and output system to call. Therefore, in one embodiment, loading the preset channel configuration information includes: loading the channel configuration information from the memory corresponding to the basic input and output system; the channel configuration information includes: input and output configuration, default output state, interrupt configuration, interrupt mode, read input state, read output state, output state and ESPI (Enhanced Serial Peripheral Interface) clock. Specifically, read the channel configuration information from the complex programmable logic device; store the read channel configuration information into the memory corresponding to the basic input and output system; load the channel configuration information based on the memory.

[0076] S102 : Initialize each virtual channel between the basic input / output system and the target device according to the channel configuration information.

[0077] In one embodiment, before initializing each virtual channel between the basic input / output system and the target device according to the channel configuration information, it also includes: performing configuration operations on each virtual channel. Performing configuration operations on each virtual channel includes: the basic input / output system correctly configures the ESPI rate, CRC (Cyclic Redundancy Check) check, etc. for each virtual channel; at the same time, the CPLD end also performs the same configuration operations as the BIOS for each virtual channel, including setting the ESPI rate, CRC check, etc. The virtual channel is: VGPIO. The target device can be a CPLD or a BMC (Baseboard Management Controller). In an example, the input / output state, default output state, interrupt mode, transmission rate, clock, and data verification mode to be configured for each virtual channel can be parsed from the channel configuration information; the input / output state, default output state, interrupt mode, transmission rate, clock, and data verification mode are configured for each virtual channel using a configuration tool. The configuration tool can specifically be related management software for VGPIO.

[0078] In one embodiment, if any virtual channel fails to initialize, it is detected whether the number of consecutive initializations of the virtual channel exceeds the preset number of retries; if the number of consecutive initializations of the virtual channel does not exceed the preset number of retries, the virtual channel is reinitialized; if the number of consecutive initializations of the virtual channel exceeds the preset number of retries, the initialization operation of the virtual channel is terminated.

[0079] S103 . After each virtual channel is initialized and the basic input / output system is started, first state information of each virtual channel recorded by the basic input / output system is obtained, and second state information of each virtual channel recorded by the target device is obtained.

[0080] It should be noted that the first state information of each virtual channel recorded by the basic input and output system is generated based on the configuration operation of the basic input and output system on each virtual channel; and the second state information of each virtual channel recorded by the target device is generated based on the configuration operation of the target device on each virtual channel; therefore, if the basic input and output system and the target device perform the same configuration operation on the same virtual channel and the configuration is successful, the first state information and the second state information of the same virtual channel are consistent; on the contrary, the first state information and the second state information of the same virtual channel will be consistent. It can be seen that the first state information of each virtual channel can be determined according to the information configured by each virtual channel; the first state information of each virtual channel is written into the channel register corresponding to each virtual channel; and the first state information of each virtual channel is obtained by reading from the channel register corresponding to each virtual channel.

[0081] In one implementation, obtaining the first status information of each virtual channel recorded in the basic input / output system includes: reading the first status information of each virtual channel from a channel register corresponding to each virtual channel.

[0082] S104: Determine abnormal virtual channels whose first status information and second status information are inconsistent, and determine corresponding channel diagnosis suggestion information according to the number of abnormal virtual channels.

[0083] In this embodiment, the channel diagnosis suggestion information is prompt information, and the technician can diagnose and check the abnormal virtual channel with reference to the channel diagnosis suggestion information.

[0084] In one embodiment, the corresponding channel diagnosis suggestion information is determined according to the number of abnormal virtual channels, including: detecting whether the number of abnormal virtual channels exceeds a preset number threshold; if the number of abnormal virtual channels exceeds the preset number threshold, determining that the fault level is the first fault level, and confirming the corresponding channel diagnosis suggestion information according to the first fault level includes: checking the initialization operation of the abnormal virtual channel from the basic input / output system end and the target device end respectively; checking the interface configuration of the abnormal virtual channel from the basic input / output system end and the target device end respectively; detecting the signal waveform and signal quality of the abnormal virtual channel; if the number of abnormal virtual channels does not exceed the preset number threshold, determining that the fault level is the second fault level, and confirming the corresponding channel diagnosis suggestion information according to the second fault level includes: checking the channel register corresponding to the abnormal virtual channel from the basic input / output system end; analyzing the register information in the channel register corresponding to the abnormal virtual channel and the configuration information of the target device for the abnormal virtual channel from the target device end; recording the abnormal virtual channel and the corresponding channel diagnosis suggestion information according to the preset format to obtain the target file. For example: recording the abnormal virtual channel and the corresponding channel diagnosis suggestion information to a predefined table file. The severity of the first fault level is greater than the severity of the second fault level.

[0085] In one embodiment, the channel identification information of the abnormal virtual channel and the corresponding channel diagnosis suggestion information are transmitted to a preset terminal; the channel identification information of the abnormal virtual channel and the corresponding channel diagnosis suggestion information are displayed using the preset terminal. The basic input and output system of the host communicates with the preset terminal through a serial port.

[0086] It can be seen that this embodiment uses the basic input and output system to compare the first state information of each virtual channel recorded locally by the host with the second state information of each virtual channel recorded by the target device, and then determines the abnormal virtual channels whose first state information and second state information are inconsistent, so as to determine the corresponding channel diagnosis suggestion information according to the number of abnormal virtual channels. Referring to this channel diagnosis suggestion information, it is convenient to locate the VGPIO communication anomaly between the host BIOS and the CPLD, which is helpful to clarify the location and cause of the communication obstruction.

[0087] Since the CPLD in the server can communicate with the BIOS through VGPIO, this application can be applied to the BIOS of the server. VGPIO is part of the ESPI protocol. The host and CPLD can communicate with each other through ESPI, without adding additional hardware resources. In addition, PCIe bandwidth information, BIOS startup status, etc. can be communicated with the CPLD through VGPIO.

[0088] VGPIO refers to virtual GPIO, which is implemented by transmitting GPIO information through the ESPI virtual line channel. The physical GPIO has physical pins, but the VGPIO does not have physical pins. The host and the slave can transmit virtual GPIO information through ESPI without connecting physical pins.

[0089] More specifically, the Virtual Wire Channel is used to convert the status of the sideband pin and GPIO communicated through eSPI into inband messages. The SerialIRQ interrupt communicates through this channel in the form of inband messages. The Virtual Wire Packet begins with the Virtual Wire Count byte, and this count indicates the number of Virtual Wire groups communicated by this packet. Then follows a number of Virtual Wire Groups. Each Virtual Wire Group contains 2 bytes, called the Virtual Wire Index and Virtual Wire Data. In one packet, up to 64 Virtual Wire Groups can be sent. The number of Virtual Wire Groups in a VW Packet cannot exceed the Operation Maximum Virtual Wire count in the Capabilities and Configuration Register of Channel 1. This applies to both Master and Slave. The eSPI Slave must declare support for more than 8 Virtual Wire Groups in a single VW Packet. The Virtual Wire Index points to a predefined Virtual Wire. The format of the Virtual wiredata is related to the associated virtual wire index. This contains specific information about the set of virtual wire groups being communicated. Unused Virtual WireSlots within a specific Virtual Wire Index should remain in a reserved state. The initiator must drive the reserved area to 0 and the receiver must ignore the reserved area. The Virtual Wire Packet is not subject to flow control. As long as the VW Channel is open, the receiver must always be prepared to receive a Virtual Wire packet at any time. The length of the Virtual Wire Packet is (1+2*n) bytes, where n is the number of Virtual wire groups in the packet.VW Index 128-255 is used for GPIO and VGPIO communication. This application uses the virtualization channel of ESPI to communicate with CPLD, checks the status of VGPIO, and gives the inspection results, so that users can quickly locate the problem.

[0090] The CPLD system has a dedicated module to control VGPIO, and the HOST side also has a dedicated VGPIO control register. The HOST side needs to correctly configure the ESPI rate and correctly enable the CS1 device before it can communicate with the CPLD. The VGPIO control register will be mapped to an address space, and whoever accesses these address spaces will access the corresponding registers.

[0091] See also Figure 2 , the connection between CPLD and host is as follows Figure 2 Generally, there can be 64 VGPIOs between the host CPU and CPLD, each of which can be configured and controlled separately. Due to the large number, the BIOS and CPLD need to communicate in advance and set a table to compare the configurations of both parties. The table includes VGPIO input and output configuration, interrupt configuration, default state, etc., as shown in Table 1.

[0092] Table 1

[0093]

[0094] Both BIOS and CPLD need this table. CPLD can provide this table in advance, and then the BIOS can enter it into a memory range during the boot process. It can also provide registers for BIOS to access so that the BIOS can dynamically update this table to the memory range. During the boot process, the BIOS will check all VGPIOs on the host side that communicate with the CPLD, and then output the results to the reserved memory space.

[0095] See also Figure 3 The method steps for detecting the VGPIO communication status between BIOS and CPLD include:

[0096] Step 1: BIOS and CPLD communicate via ESPI.

[0097] BIOS enables CS1 signal and VGPIO function. The host side correctly configures ESPI rate through the configuration table. Meanwhile, the CPLD side must also match BIOS, including setting ESPI rate, CRC check, etc.

[0098] Step 2: During the boot process, BIOS initializes VGPIO through the GPIO list. If the initialization process is successfully configured, it proceeds to step 3, otherwise it retries. When the number of retries to initialize VGPIO exceeds the preset number, it is considered that VPGIO initialization has failed, and the VGPIO automatic detection action ends.

[0099] The GPIO list includes: input and output settings, interrupt settings, default value settings, etc. The BIOS boot process loads the configuration table from the memory, and the content of VGPIO initialization is the content listed in the list.

[0100] Step 3: After the BIOS successfully initializes VGPIO, it will apply for a certain amount of memory space. It will not immediately record the current status to this memory area, but will wait until the beginning of the boot process and directly obtain the VGPIO status through the host's VGPIO register.

[0101] The VGPIO status includes: input-output relationship and signal. The register records the lowest level status, so what is obtained through the register is the actual configuration and current status of the final VGPIO, and the status set by the function is not necessarily the final result. The obtained VGPIO status is filled into the memory area in the form of a table according to the pre-agreed table.

[0102] Step 4: BIOS obtains VGPIO status from CPLD.

[0103] BIOS provides a Setup interface to input static VGPIO status to CPLD, or CPLD can provide registers so that BIOS can access the registers through interfaces such as I2C. In either case, the CPLD's VGPIO settings need to be correctly obtained.

[0104] Step 5: Start comparative analysis.

[0105] For example, for VGPIO-68, the BIOS setting is input, and the CPLD setting is output. If the output state provided by the CPLD is High, and the state obtained by the BIOS from the register is also High, then the two sides are consistent and the match passes. If they are inconsistent, an exception is recorded.

[0106] Step 6: Output all abnormal results and give diagnostic suggestions.

[0107] Case 1: If most VGPIO states are abnormal, the following suggestions are output:

[0108] (1) Consider whether the VGPIO initialization on both the BIOS and CPLD sides is configured correctly;

[0109] (2) BIOS detects ESPI settings;

[0110] (3) CPLD detects the ESPI settings and checks the VGPIO input and output logic;

[0111] (4) Hardware measures the ESPI signal waveform to confirm the signal quality.

[0112] Case 2: If a few VGPIOs are abnormal, the following suggestions are output:

[0113] (1) Check whether the BIOS register settings are correct for abnormal VGPIO;

[0114] (2) If the BIOS register settings are correct, it is recommended that the CPLD perform the analysis and processing.

[0115] Step 7: The comparison results and diagnostic data will be output to the serial terminal. Users can collect serial logs to obtain results and allow R&D personnel in related fields to quickly analyze according to diagnostic suggestions. It can be seen that when the VGPIO status is abnormal, relevant information will be printed to the serial terminal.

[0116] In this example, the relevant results can also be uploaded to the cloud for further diagnosis and analysis, or a cloud-based diagnosis engine can be established to achieve accurate diagnosis through large amounts of data training.

[0117] It can be seen that in this embodiment, the host side can directly read the VGPIO register configuration status and then save it in the memory area, and can obtain the actual VGPIO status set from the CPLD side, and compare and analyze the two data after obtaining them, and give relevant inspection suggestions for the difference items, thereby automatically checking the VGPIO settings between the BIOS and the CPLD, reducing unnecessary debugging time. This method is not limited to BIOS and CPLD, but also applies to the VGPIO status check between the BIOS and the BMC. There is also VGPIO communication between the BIOS and the BMC. Extending this method to the BMC field can achieve the same effect.

[0118] Accordingly, this embodiment can solve the problem that when CPLD and BIOS have problems in transmitting information (including PCIe bandwidth information, board ID information, etc.) using VGPIO, a configuration comparison list is generated according to the register setting and the configuration of CPLD. The two sides will compare and quickly locate which VGPIO communications have abnormalities, check the VGPIO configuration errors or logic errors at both ends, reduce the debugging time, and thus greatly improve the efficiency of solving this problem.
