if so, it may be determined that an MCTP type packet is detected.
Specifically, the data packet includes a data type field for displaying the type of the data packet, and whether the data packet is of the MCTP type is determined according to the type of the recorded message in the data type field. For example, when a packet is obtained through the PCIe bus, whether the content of the Field is the value of the MCTP VDM Code may be determined according to the PCIe TAG Field of the packet, and if so, it indicates that the packet is of the MCTP type, and then it is determined that the packet of the MCTP type is detected.
Step S102: reading frame data needing to be sent from the register according to the configuration information, verifying the frame data, and converting the frame data passing the verification into sending data meeting the sending format requirement to carry out sending operation;

The processor appoints the address of the frame descriptor stored in the register, so that different frame descriptors can be realized, and the frame descriptors are stored discontinuously in the register, thereby enhancing the flexibility of using the storage space of the register. Furthermore, as the frame data transmission rate is faster than the frame descriptor transmission rate, the acquired frame descriptor can be temporarily stored in order to ensure the continuity of the frame data acquisition process.

Further, the processor may generate a corresponding frame descriptor including the storage address information of the received data according to the received data, control the register to store the frame descriptor, and send the storage address information of the frame descriptor to the MCTP controller, the MCTP controller obtains the frame descriptor according to the storage address information, and obtains the storage address of the received data by analyzing the frame descriptor. Since the storage address of the received data is specified by the processor, the flexibility of storing the received data is increased.
In one embodiment, after the received data is stored to the predetermined address, an interrupt message is generated and sent to the processor to feed back that the received data is stored in the register, thereby prompting the processor to perform a read operation.
The invention provides a method for controlling data transmission and reception of an MCTP controller, which comprises the following steps: judging whether configuration information sent by a processor is received or a data packet of an MCTP type is detected: if the configuration information is received, reading frame data needing to be sent from the register according to the configuration information, verifying the frame data, and converting the frame data passing the verification into sending data meeting the sending format requirement to carry out sending operation; and if the data packet is detected, reading the data packet and verifying the data packet, converting the data packet passing the verification into the received data meeting the requirement of the receiving format and writing the received data into the preset address. Therefore, the invention provides a process of controlling data transceiving by the controller based on the MCTP protocol, and brings convenience to the work of platform developers.

It is understood that, one or more of the verification operations may be selected by those skilled in the art to verify the frame data according to the actual application, and the embodiment of the present invention is not limited thereto. When the error of the check is found, the interrupt is reported to the processor, the retransmission mechanism is started, and new frame data is newly acquired, so that the transmission of error frame data is avoided.
In one embodiment, according to the configuration information, reading frame data to be transmitted from the register specifically includes:
and establishing connection with the register through the current target interface indicated in the configuration information, and reading frame data needing to be sent.
In particular, the processor may determine a current target interface that is currently available from a plurality of interfaces provided by the registers. For example, the register is provided with a DMA interface and an AXI interface, and when the DMA interface is transferring video data having a large data volume, the processor may indicate in the configuration information that the current target interface is the AXI interface. The MCTP controller establishes connection with the register through the current target interface so as to read the frame data needing to be transmitted. The flexibility of reading the frame data is ensured, and the processor can continuously send down the related information of the frame data. Further, when the received data is written into the preset address, the processor may also determine the target interface, and establish a connection with the target interface so as to write the received data into the preset address.
In one embodiment, after reading the data packet and checking the data packet, the method further includes:
and performing packet loss operation on the data packet which is not checked.
Specifically, for a data packet which fails to pass the verification, the packet loss operation is not performed; according to different errors of the data packet in the checking process, different packet loss operations can be performed, including discarding the current frame or discarding all the data packets. And when the packet loss operation is finished, generating loss information and feeding the loss information back to the sending end, and requiring the sending end to resend the loss information.

determining a bus type used for sending frame data, and converting the frame data passing the verification according to the sending format requirement of the bus type;
and transmitting the converted transmission data through the bus.
6. The MCTP controller data transmission and reception control method according to claim 5 wherein the bus type is specifically: I2C type, SMBus type, PCIe type, or RMII type.
7. The MCTP controller of claim 1, wherein the reading, according to the configuration information, frame data to be transmitted from a register specifically comprises:
and establishing connection with the register through a current target interface indicated in the configuration information, and reading the frame data required to be sent.
8. The MCTP controller as claimed in claim 1, wherein after reading and verifying the data packet, the MCTP controller further comprises:
and performing packet loss operation on the data packet which is not checked.
9. A control apparatus for transmitting and receiving data by an MCTP controller, comprising:
the judging module is used for judging whether the configuration information sent by the processor is received or a data packet of the MCTP type is detected: if the configuration information is received, entering a sending module; if the data packet is detected, entering a receiving module;
the sending module is used for reading frame data needing to be sent from the register according to the configuration information, verifying the frame data, and converting the frame data passing the verification into sending data meeting the sending format requirement to carry out sending operation;
and the receiving module is used for reading the data packet, verifying the data packet and converting the data packet passing the verification into receiving data meeting the receiving format requirement and writing the receiving data into a preset address.
10. A control apparatus for transmitting and receiving data by an MCTP controller, comprising a memory for storing a computer program;
a processor for implementing the steps of the method for controlling the MCTP controller to transmit and receive data according to any one of claims 1 to 8 when executing the computer program.
