TECHNICAL FIELD

[0001] The present application relates to the technical field of data processing, and in particular to a data processing method and device and electronic equipment. BACKGROUND

[0002] The solid state disk is a data storage product connected to the host by SATA (Serial Advanced Technology Attachment) or PCIE (Peripheral Component Interconnect Express) and the like, and driven and controlled by the corresponding controller, and initiates services from the application layer.

[0003] The solid state disk connected through the PECI line transmits data in the NVME (Non-Volatile Memory Express) protocol, and the solid state disk connected through the SATA line transmits data in the SATA protocol. The SATA, NVME and the like protocols can define many commands for the application layer to initiate related services, but these commands cannot meet the related service requirements in some special scenarios, such as reading the bad block information of the solid state disk and burning the firmware, which usually requires the disk manufacturer to define some commands.

[0004] In the prior art, there are some reserved fields in the SATA and NVME protocol commands, and some commands are usually defined by using these reserved fields. The reserved fields are generally small, and the extensibility of the defined commands is poor. SUMMARY

Each first read command carries a tag value corresponding to the first read command. Based on the random number, a data processing command is sent to the solid state disk in the specified working mode, so that the solid state disk processes data corresponding to the data processing command according to the data processing command. The data processing command comprises a second read command or a first write command.

[0007] Further, if the data processing command is the first write command, the first write command carries the random number, the tag value corresponding to the first write command and the data to be written; based on the random number, the data processing command is sent to the solid state disk in the specified working mode, so that the solid state disk processes the data corresponding to the data processing command according to the data processing command.

If the data processing command is the second read command, the second read command is sent to the solid state disk in the specified working mode, so that the solid state disk returns the data to be read corresponding to the second read command according to the second read command.

[0009] Further, based on the random number, the data processing command is sent to the solid state disk in the specified working mode, so that the solid state disk processes the data corresponding to the data processing command according to the data processing command. The step of sending the second write command to the solid state disk in the specified working mode, so that the solid state disk determines the data category corresponding to the command parameter according to the command parameter carried by the second write command; wherein the second write command also carries the random number and the tag value corresponding to the second write command; the data processing command is sent to the solid state disk in the specified working mode, so that the solid state disk processes the data corresponding to the data processing command which belongs to the data category to be processed.

[0026] The technical solutions of the present application will be described below in conjunction with embodiments, obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0027] The solid state disk is a data storage product connected to the host by SATA or PCIE, etc., driven and controlled by the corresponding controller, and the business data is initiated from the application layer. The SATA, NVME, etc. protocol defines many commands for the application layer to initiate related businesses, but these commands cannot meet the related business requirements in some special scenarios, and the disk manufacturers usually need to define some commands, which are generally called vender commands.

[0028] In the prior art, some commands are usually defined by using a reserved field in a SATA, NVME protocol command.

[0029] The prior art mainly has the following disadvantages:

[0030] The reserved field is generally small, as shown in a read command diagram, Figure 1 The content 3:0Reserved in the black frame marked part is a reserved field, and the size is only 3 bits, resulting in poor scalability. Figure 1

[0031] In addition, the reserved field may be selected during protocol evolution, at which time the vender command cannot adapt to the protocol specification of the version, and the detection of the command by different platform drivers is different, so the method of using the reserved field may cause poor compatibility.

[0032] In order to facilitate the understanding of the embodiment, first, a data processing method disclosed by the embodiment is introduced in detail, and the method is applied to an electronic device, the electronic device is in communication connection with a solid state disk, as shown in Figure 2 The method comprises the following steps:

[0033] Step S202, a preset number of first read commands are sent to the solid state disk, so that the solid state disk enters a specified working mode and returns a random number to the electronic device; wherein each first read command carries a tag value corresponding to the first read command.

[0034] The electronic device in the application can be understood as an application program, and the solid state disk can be understood as a computer storage device mainly using flash memory as a permanent memory, which can be simply referred to as SSD, and is composed of a control unit and a storage unit. The main functions of the solid state disk in the computer are two, the first function is the storage function, the operating system and all software and user data are stored in the hard disk, the second function is the extraction function of all data, there is storage and there is taking, and the function is summarized as the read and write function of data.

[0035] In the specific implementation process, referring to the structure diagram of a data transmission system, Figure 3 The solid state disk can be connected to the host through a SATA line or a PCIE line, and the application program is driven and controlled by the SATA controller or the PCIE controller on the host to initiate related services.

[0036] ​Generally, the data stored in the solid state disk storage unit can include two kinds, one is user data, and the other is special data provided by the solid state disk manufacturer. The SATA protocol or the NVME protocol can define many commands, including read commands and write commands. The read command is used to read the data stored in the solid state disk storage unit, and the write command is used to write data to the solid state disk. In some special scenarios, the commands defined by the SATA protocol or the NVME protocol cannot meet the related business requirements. For example, the read command defined by the SATA protocol cannot read the bad block information (special data) of the solid state disk to the application program, because the commands defined by the SATA protocol or the NVME protocol can only be used to process user data.

[0037] In actual application, in order to be able to process the special data in the solid state disk, the application program can construct a preset number of first read commands according to the preset protocol (SATA protocol or NVME protocol). Each read command can carry a tag value corresponding to the read command. Each tag value is generally a special value previously negotiated by the electronic device and the solid state disk end. Although each tag value is generally a special value that is not common, there is still a situation that one of the tag values is the same as the tag value carried by the command for processing user data. Therefore, sending all the preset number of first read commands to the solid state disk can play a reminding role, reminding the solid state disk that the current received read-write command may be a link in the entire process of processing special data, and it cannot be completely determined. Therefore, after receiving the preset number of first read commands, the solid state disk returns a generated random number to the application program to further determine whether the current received read-write command is a link in the entire process of processing special data (corresponding to entering a specified working mode).

[0038] Step S204, based on the random number, a data processing command is sent to the solid state disk in the specified working mode, so that the solid state disk processes the data corresponding to the data processing command according to the data processing command. The data processing command includes a second read command or a first write command.

[0039] The application program receives the random number sent by the solid state disk, and sends a data processing command to the solid state disk in the specified working mode (judging whether the current received read-write command is a link in the entire process of processing special data) to make the solid state disk finally determine that the current received read-write command is a link in the entire process of processing special data, and process the data corresponding to the data processing command.

[0040] The application provides a data processing method, which is applied to an electronic device in communication connection with a solid state disk; the method comprises the following steps: sending a preset number of first read commands to the solid state disk, so that the solid state disk enters a specified working mode and returns a random number to the electronic device; wherein each read command carries a tag value corresponding to the read command; based on the random number, a data processing command is sent to the solid state disk in the specified working mode, so that the solid state disk processes data corresponding to the data processing command according to the data processing command; wherein the data processing command comprises a second read command or a first write command. In this way, the preset number of first read commands and the data processing command are used to jointly form a custom command, the data area of the first read command and the data processing command is relatively large, more custom commands can be defined, and the expansibility is enhanced.

[0041] The application also provides another data processing method, which is implemented on the basis of the method in the above embodiment; as shown in the figure, the method comprises the following steps: Figure 4

[0042] In step S402, a preset number of first read commands are acquired.

[0043] In step S404, each first read command is sent to the solid state disk in a preset order.

[0044] In step S406, if there is a first read command that fails to be sent, the step of sending each first read command to the solid state disk in a preset order is repeated until each first read command is successfully sent.

[0045] In the specific implementation process, the application program can construct a preset number of first read commands, a second write command and a data processing command (a first write command or a second read command) according to a preset protocol (SATA protocol or NVME protocol), and each read command and write command can carry a corresponding tag value. The preset number of first read commands, the second write command and the data processing command can form a read-write command sequence in a preset order. Assuming that there are three first read commands, the order of the read commands and the write command in the read-write command sequence is: the first read command, the second read command, the third read command, the second write command and the data processing command; the three first read commands are sent to the solid state disk in the order of the first read command, the second read command and the third read command. If any of the three first read commands fails to be sent, the step of sending the three first read commands to the solid state disk in the order of the first read command, the second read command and the third read command is repeated until the first read command, the second read command and the third read command are successfully sent.

[0046] ​Step S408, receiving the data corresponding to each first read command returned by the solid state disk, and controlling the solid state disk to enter the specified working mode; wherein the data returned by the last sent first read command is a random number.

[0047] In actual implementation, after successfully receiving the first read command, the solid state disk returns the data corresponding to the first read command to the application program; after successfully receiving the second read command, the solid state disk returns the data corresponding to the second read command to the application program; after successfully receiving the third read command, the solid state disk enters the specified working mode and returns a random number to the application program.

[0048] Step S410, sending a second write command to the solid state disk in the specified working mode, so that the solid state disk determines the data category to be processed corresponding to the command parameter according to the command parameter carried by the second write command; wherein the second write command also carries a random number and a tag value corresponding to the second write command.

[0049] After receiving the random number, the application program sends a second write command to the solid state disk, returns the tag value corresponding to the second write command and the random number to the solid state disk. Only when processing special data, the random number will be returned to the solid state disk again. When processing user data, the random number will not be returned. Therefore, after receiving the random number and the tag value corresponding to the second write command, the solid state disk determines that the current read-write command is a link in the entire special data processing process, so that only special data is processed and user data is not processed, thereby ensuring the safety of user data.

[0050] In the specific implementation process, the second write command also carries a command parameter, and different command parameters correspond to different special data types (equivalent to data categories to be processed), such as 0x2 indicating processing of log information and 0x1 indicating processing of ring block information. Therefore, the solid state disk can determine which special data to process according to the command parameter.

[0051] Step S412, sending a data processing command to the solid state disk in the specified working mode, so that the solid state disk processes the data corresponding to the data processing command which belongs to the data category to be processed.

[0052] In the specific implementation process, the specific business initiated by the application program determines whether the data processing command is a first write command or a second read command. For example, when the initiated business is to read bad block information, the data processing command is a second read command; when the initiated business is to burn firmware, the data processing command is a first write command.

[0053] If the data processing command is the first write command, the first write command carries a random number, the tag value corresponding to the first write command, and the data to be written. After the electronic device (application) sends the first write command to the solid-state drive in the specified working mode, it writes the data to be written carried by the first write command into the special data type corresponding to the command parameter.

[0054] If the data processing command is a second read command, the second read command carries a random number and the tag value corresponding to the second read command. After the electronic device sends the second read command to the solid-state drive in the specified working mode, the solid-state drive returns the data to be read corresponding to the second read command in the special data type of the command parameters to the electronic device.

[0055] To better understand the above embodiments, this application provides a method such as... Figure 5 The diagram illustrates a process for processing special data. As can be seen from the diagram, the entire process can be divided into three main parts: the first part is the handshake stage (which reminds the SSD that the read / write command it is currently receiving may be a step in the process of processing special data); the second part is the vendor mode stage (which further determines whether the read / write command the SSD is currently receiving is a step in the process of processing special data); and the third part is the special data processing stage (which determines that the read / write command the SSD is currently receiving is a step in the process of processing special data).

[0056] The "handshake" phase involves the first n read commands (a preset number of first read commands) being sent to the SSD in a predetermined order, and the corresponding data being returned. Each read command carries a unique tag, which can be a pre-negotiated value between the application and the disk (such as a special logical block address 0x12345). This tag indicates that it is one of a custom command (a sequence of read and write commands) designed to process special data on the SSD and requires special handling. Specifically, read command 1 with tag-1 is sent to the SSD first, and the corresponding data is returned. Then, read command 2 with tag-2 is sent to the SSD, and the corresponding data is returned. Each read command operates in this manner until read command n with tag-n (the last first read command) is successfully sent to the SSD. Only then is the entire "handshake" phase successfully completed. The handshake phase described above only serves as a reminder to the SSD that the currently received read / write command may be part of the entire process of processing special data, but it does not completely confirm this.

[0057] In order to further determine whether the current received read-write command is a link in the whole process of processing special data, the solid state disk enters a vender mode (enters a specified working mode), generates a random pattern (special pattern) and sends the random pattern to the application program. After that, the read command or the write command sent by the application program is provided with a corresponding special tag and the random pattern returned by the solid state disk. The solid state disk can always correctly recognize the remaining read-write command of the vender command (self-defined command), thereby only processing the special data and ensuring the safety of user data. Specifically, the application program receives the random pattern, and returns a write command (second write command) with a tag-n+1, a pattern and an arg (command parameter) to the solid state disk. The random pattern is a random number generated and returned by the solid state disk. When the application program returns the pattern to the solid state disk, the disk can more clearly determine that the current received read-write command is a link in the whole process of processing special data.

[0058] After the determination, the application program then sends a read command with a tag-n+2, a pattern or a write command with a tag-n+2, a pattern and data to be written (data) to the solid state disk (second read command or first write command), for processing the special data in the solid state disk. If the read command (second read command) is sent, the solid state disk also needs to return the special data corresponding to the command parameters in the second read command and the second write command to the application program.

[0059] From Figure 5 It can be seen that the self-defined command is composed of multiple read-write commands in a fixed order. In order to better understand the above embodiment, the application further provides a self-defined command as shown in Figure 6The execution flowchart of a self-defined command (vender command) is shown; when the vender command starts, n read commands with a special tag are sent to handshake with the solid state disk to ensure that the solid state disk correctly enters the vender command mode, the commands in the handshake stage are all read commands and cannot damage user data. If there is any read command in the handshake stage that is not successfully sent to the solid state disk (read command sending fails), the vender command restarts until all the read commands in the handshake stage are successfully sent, when the last read command n is successfully sent, the handshake succeeds, the solid state disk enters the vender mode, and a random pattern is returned, and a write command with a special tag, pattern and arg is continuously sent to the solid state disk, if the sending fails, the vender command restarts, if the sending succeeds, a write command with a special tag, pattern and data (to be written data) is continuously sent to the solid state disk, or a read command with a special tag, pattern and data (to be read data) is continuously sent to the solid state disk, if the sending fails, the vender command restarts, if it is a write command, the whole process is directly ended after the write command is successfully sent, if it is a read-write command, the solid state disk returns the data (to be read data) corresponding to the read command first after the read command is successfully sent, and then the whole process is ended.

[0060] The application provides a data processing method and device and electronic equipment, the method is applied to the electronic equipment, and the electronic equipment is in communication connection with a solid state disk; in the method, a combination of a first read command, a second write command, a first write command or a second read command is a command defined by a SATA or NVME protocol, so that a preset number of combinations of the first read command, the second write command, the first write command or the second read command are used to form a self-defined command (equivalent to a combination of read-write commands used to form a self-defined command), and there is no compatibility problem in any platform. In the application, the first read command, the second write command, the first write command or the second read command all use a special tag, and the second write command, the first write command or the second read command also returns a random pattern, so that the safety of user data can be effectively ensured. Compared with a reserved field in a read-write command, a data area of the read-write command is much larger, so that more self-defined commands can be defined if the combination of the read-write commands is used to form the self-defined command, and the expansibility is enhanced.

[0061] The application further provides a data processing device, which is arranged on an electronic equipment and is in communication connection with a solid state disk. Figure 7As shown, the device comprises: a first sending module 70, configured to send a preset number of first read commands to the solid state disk, so that the solid state disk enters a specified working mode, and returns a random number to the electronic device; wherein each first read command carries a tag value corresponding to the first read command; a second sending module 71, configured to send a data processing command to the solid state disk based on the random number, so that the solid state disk processes data corresponding to the data processing command according to the data processing command; wherein the data processing command comprises a second read command or a first write command.

In the device, the preset number of first read commands and the data processing command jointly constitute a custom command, the data area of the first read command and the data processing command is relatively large, more custom commands can be defined, and the expansibility is enhanced.

[0063] Further, if the data processing command is a first write command, the first write command carries the random number, the tag value corresponding to the first write command and to-be-written data; the second sending module is further configured to: if the data processing command is a first write command, a first write command is sent to the solid state disk in the specified working mode, so that the solid state disk writes the to-be-written data according to the first write command.
