[0002] NVMe Admin Commands are a series of management commands for NVMe (Non Volatile Memory Express, a communication interface) SSD (Solid State Disk, solid state disk) subsystems defined in the NVM Express Base Specification. The host software manages NVMe SSD devices in-band through these commands. The NVM Express Management Interface Specification is a supplement to the NVM Express Base Specification protocol, which defines a management interface that supports communication with NVMe SSD devices out-of-band.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0040] At present, different processing methods are used to process the Admin commands sent in-band and the Admin commands sent out-of-band, and this data processing method has the problem of code redundancy in the system. To this end, the present application provides a data interaction method, which uses the same Admin processing function to process the data sending commands sent in-band and out-of-band, respectively, avoiding the problem of code redundancy.
[0041] See also Figure 1 As shown, an embodiment of the present invention discloses a data interaction method, which is applied to a solid state drive, including:
[0042] Step S11, extracting the target data sending command from the preset target Admin processing linked list based on the serial processing method; wherein, the preset target Admin processing linked list is a preset in-band Admin processing linked list or a preset out-of-band Admin processing linked list, and the preset in-band Admin processing linked list and the preset out-of-band Admin processing linked list respectively store the data sending commands for in-band sending and out-of-band sending, and the data sending commands for in-band sending and out-of-band sending both reuse the same target Admin processing function.
[0043] In this embodiment, before extracting the target data sending command from the preset target Admin processing linked list, it also includes: formatting the target data sending command sent out-of-band to obtain a converted data sending command, and storing the target data carried in the target data sending command sent out-of-band in a buffer corresponding to the converted data sending command; specifically, for the Admin command sent out-of-band, that is, the data sending command sent out-of-band, when the MI (ManagementInterface) module receives the Admin command sent out-of-band, it parses the command message, assembles the command message into a standard Admin SQE (Submission Queue Entry) format, and places the data carried in the out-of-band Admin command, that is, the target data, in the buffer. It should be noted that the above-mentioned buffer is applied for by the MI module, and the size and address of the buffer are borrowed from the SGL field (Scatter Gather) in the DTPR (DataPointer) bit in the Admin SQE message format. List, that is, the above buffer is described by the address and length of the SGL field (address represents the address of the storage buffer, and length represents the size of the storage buffer). It should be noted that the data carried in the out-of-band Admin command can also be stored using the PRP (Physical Region Page) field in the DTPR bit.
[0044] In this embodiment, before extracting the target data sending command from the preset target Admin processing linked list, it also includes: obtaining the data sending command sent in-band and the data sending command sent out-band, and storing the data sending command sent in-band and the data sending command sent out-band to the preset in-band Admin processing linked list and the preset out-band Admin processing linked list respectively; the above storage process is the responsibility of the in-band Admin processing module, that is, the in-band Admin processing module receives the Admin command message sent by MI, and puts the commands from MI, that is, the target data sending command sent out-band and the Admin command sent in-band, that is, the target data sending command sent in-band, into different processing linked lists in sequence, that is, the preset in-band Admin processing linked list and the preset out-of-band Admin processing linked list.
[0045] In this embodiment, a serial processing method is used when extracting the target data from the target Admin processing linked list to send the command, such as Figure 2As shown, each task scheduling loop only processes one Admin command message, and processes the Admin commands in different linked lists in turn; when processing a specific Admin command, the same set of command processing functions, namely the target Admin processing function, is called; when processing commands, the target data sending commands can be extracted from the in-band Admin processing linked list and the out-of-band Admin processing linked list in turn according to the order in which the commands are received.
[0046] It should be noted that the functions of Admin commands implemented by in-band sending and Admin commands implemented by out-of-band sending are completely overlapping, but the calling channels are different. The MI protocol defines the request message format for sending Admin commands out-of-band, where the contents of bytes 8-27 correspond to the NVMe in-band command format Submission Queue Entry Dword 1-5, bytes 44-67 correspond to the NVMe in-band command format Submission Queue Entry Dword 10-15, and bytes 68 and the following fields define the data that may be carried by the Admin command. The difference is that the Admin command sent using the out-of-band mechanism in the MI protocol sends the data that may be carried as part of the command message, rather than using the PRP list or SGL segment transmission (two ways of transmitting data using the in-band mechanism), that is, the data carried by the in-band Admin command is transmitted through DMA (Direct Memory Access, i.e. direct storage access technology). The SSD device obtains the specific address of the data in the Host memory through the DTPR field in the SQE and moves the data through DMA; the data carried by the out-of-band Admin command is transmitted as part of the command message; and the in-band Admin SQE defines two addressing modes for DMA: PRP and SGL. The essential difference between PRP and SGL is that PRP must be physically page aligned, while SGL can represent any physical space; and the Admin command sent out-of-band can carry target data. When the host does not need to transfer data to the SSD, the command may not carry target data; in the MI request message field, that is, the Admin command sent out-of-band, the DPTR and MPTR (Memory Pointer) fields in the command, that is, the SGL field, are reserved and unused. Since the command format sent in-band overlaps with the command format sent out-of-band, the same set of command processing functions can be used for processing. By storing commands in different processing linked lists according to the sending method of the Admin command, the reliability of data classification is improved.
[0047] Step S12: acquiring target data corresponding to the target data sending command according to the target data sending command and the target sending mode corresponding to the target data sending command.
[0048] In this embodiment, the method of obtaining the target data is determined by the target sending method corresponding to the target data sending command. In a specific implementation, if the target sending method corresponding to the target data sending command is out-of-band sending, the target data contained in the target data sending command is copied to the target buffer to obtain the target data corresponding to the target data sending command; in another specific implementation, if the target sending method corresponding to the target data sending command is in-band sending, the target data on the memory of the target host is moved using the target data sending command and the direct storage access technology to obtain the target data corresponding to the target data sending command, that is, if the host has data to send to the SSD, the in-band processing method is to move it from the host memory through DMA, and because the out-of-band data is directly packaged in the MI request data structure, that is, the data sending command sent out-of-band, the processing method needs to be modified accordingly. If it is determined that the command is from the MI out-of-band channel, the DMA moving process is skipped, and the data is copied from the MCTP (Management Component Transport Protocol) message, that is, the target data sending command sent out-of-band to the target buffer of the DMA read. It should be noted that if the SSD has data to send to the host, the in-band data is also moved through DMA, and the out-of-band message is directly packaged in the response message, and does not need DMA movement. By using the target sending method corresponding to the target data sending command, the target data is obtained by different data acquisition methods, which improves the rationality of the data interaction process.
[0049] Step S13, calling the target Admin processing function, generating a target response message corresponding to the target data according to the target sending mode and the target Admin processing function, and sending the target response message to the target host that generates the target data sending command.
[0050] In this embodiment, the process of generating a target response message corresponding to the target data according to the target sending mode and the target Admin processing function specifically includes: if the target sending mode is in-band sending, the target response information corresponding to the target data is generated by using the target Admin processing function; if the target sending mode is out-of-band sending, the target Admin processing function is fine-tuned, and the initial response information is generated according to the fine-tuned processing function, and the format of the initial response information is converted to obtain the target response information corresponding to the target data; it should be noted that the above-mentioned target Admin processing function is a processing function corresponding to the target data sending command sent in-band. If the sending mode corresponding to the target data sending command is in-band sending, the target Admin processing function can be used to directly generate the target response message corresponding to the target data; if the target The sending mode corresponding to the target data sending command is out-of-band sending. Since the target Admin processing function is the processing function corresponding to the target data sending command sent in-band, the target Admin processing function needs to be fine-tuned so that the fine-tuned function can process the target data sending command sent out-of-band. It should be noted that the response message generated by the fine-tuned function is an initial response message that does not have the corresponding format of the out-of-band sending mode; after the fine-tuned target Admin processing function generates the initial response message, it will store the initial response message in the buffer. When it is necessary to return a response message to the host, the initial response message is obtained from the buffer, and the initial response message is assembled into a target response message. The relevant content of the response message is provided to the MI module through shared memory, and the MI module sends the CQE (Completion The present application innovatively utilizes the SGL field for data transmission. Specifically, when the out-of-band Admin command carries target data, the MI module passes the target data to the Admin processing module through the SGL field, and the Admin processing module transmits the response message back to the MI module through the buffer corresponding to the SGL field. When the response message carries data that needs to be transmitted to the host, the MI module uses the SGL field to pass the buffer to the Admin processing module, and the Admin processing module uses the buffer to pass the response message and the data to be transmitted to the MI module. When the host does not need to transmit data to the solid-state drive, it is still necessary to use the MI module to apply for the creation of the above buffer and pass the empty buffer to the Admin processing module so that the Admin processing module can pass the response message to the MI module. Moreover, in addition to reusing the same Admin processing function, the present embodiment also reuses the same set of Admin command processing framework.It is understandable that, in the process of receiving out-of-band Admin commands, the SGL buffer, i.e., the above buffer, is used to store the additional data in the request message; after processing the Admin command, the buffer corresponding to the SGL field stores the CQE message and the additional data in the initial response message; therefore, when applying for the buffer, it is necessary to ensure that the buffer size can accommodate the CQE data structure. By reusing the same Admin processing function and Admin command processing framework, the problem of interference between the Admin commands sent in-band and the Admin commands sent out-of-band during processing is solved.
[0051] It can be seen that the present application utilizes the same Admin processing function and command processing framework to process data sending commands with in-band sending and out-of-band sending modes respectively, thereby avoiding the use of different data sending modes to process in-band sending and out-of-band sending commands respectively, thereby solving the problem of code redundancy; by utilizing a serialized processing method, a target data sending command is extracted from the target Admin processing linked list each time, and by reusing the same Admin processing function and command processing framework, the problem of command interference caused by different callers of in-band and out-of-band Admin commands is solved.
[0052] Based on the above embodiments, it can be seen that the present application describes the specific work of the solid state drive part during the data interaction process. In order to make the technical solution of the present application more complete, the present application will next describe the work of the target host during the data interaction process. Figure 3 As shown, the embodiment of the present application provides a data interaction process, which is applied to a target host and includes:
[0053] Step S21, generating a target data sending command; the target data sending command is a data sending command for in-band sending or out-of-band sending, and both the data sending commands for in-band sending and out-of-band sending reuse the same target Admin processing function.
[0054] Step S22, sending the target data sending command to the solid state drive, so that the solid state drive obtains the target data corresponding to the target data sending command according to the target data sending command and the sending method of the target data sending command, and uses the target Admin processing function to generate a target response message corresponding to the target data.
[0055] Step S23: receiving the target response message sent by the solid state drive.
[0056] It can be seen that the present application utilizes the same Admin processing function to process data sending commands with in-band sending and out-of-band sending modes respectively, thereby avoiding using different data sending modes to process in-band sending and out-of-band sending commands respectively, thereby solving the problem of code redundancy.

[0061] It can be seen that the present application utilizes the same Admin processing function to process data sending commands with in-band sending and out-of-band sending modes respectively, thereby avoiding using different data sending modes to process in-band sending and out-of-band sending commands respectively, thereby solving the problem of code redundancy.
