With the continuous development of PCIE (peripheral component interconnect express, which is a high-speed serial computer expansion bus standard) and other various interface technologies, flash memories are continuously updated, and capacities, reading speeds and writing speeds of SSDs (Solid State Drive, solid state disks) are continuously improved. These improvements in performance also place higher demands on the processing power of the CPU (Central Processing Unit ). The measurement index IOPS (I/O Performance Units) of random reading is the number of times of reading and writing operations per second, and the higher the measurement index IOPS is, the faster the speed of reading and writing data of the hard disk is. Currently, the index requires more than million times under the condition of pcie4.0, i.e. cpu needs to process millions of times of read-write command data per second. Each operation command has a special memory structure and space for recording various information of the read-write command, called a message context. Therefore, in the process of reading and writing the memory, the SSD is necessarily accompanied with the high-frequency management information to be stored and read in the context, so that how to improve the message access rate of the CPU and improve the performance of software becomes an important direction of optimizing all SSD manufacturers.
In order to solve the above problems and achieve the purpose of fast processing the context, SSD manufacturers often have various solutions, and one common method is to enhance the processing capability of cpu or increase the number of cores cpu to provide higher computation power, so that more messages can be processed by multi-core concurrency; another is to increase the high-speed memory space, allowing the cpu to access data more efficiently. Both of these methods have a disadvantage of increasing the cost.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
In one embodiment of the present application, as shown in fig. 1, a method for processing a message context is provided, and the method is applied to a solid state disk for example, where the solid state disk includes a tightly coupled memory and a dynamic random access memory, and the method includes the following steps:
step 102, receiving a message context, the message context including input/output path necessary data and input/output path unnecessary data.
The Solid State Disk (Solid State Disk or Solid State Drive, abbreviated as SSD) is a hard Disk made of a Solid State electronic memory chip array.
Wherein the message context is various information used to record a message command, which may be, but is not limited to, various operation commands, such as a read command or a write command. That is, the message context may be understood as various descriptive information of the record message command. The message context can be obtained by analyzing the message command, and various descriptive information corresponding to the message command is obtained to obtain the message context.
The data necessary for the input/output path is data which must be accessed on the input/output path (IO path), and the data unnecessary for the input/output path is data which does not have to be accessed or has abnormal processing on the input/output path (IO path). Wherein, the data which must be accessed and the data which must not be accessed can be determined according to the access frequency.
Specifically, a message command may be received, a corresponding message context is obtained through the message command, and the message context is classified to obtain data that must be accessed on the input/output path and data that must not be accessed on the input/output path, so as to obtain necessary data of the input/output path and unnecessary data of the input/output path.
Step 104, obtaining the target idle context block from the idle context unidirectional link list of the close-coupled memory.
The tightly coupled memory (Tightly Coupled Memory, TCM) is tightly coupled to the processor core, primarily for storage. The idle context unidirectional link list is a unidirectional link list which is not written with any data and is used for storing the message context, and comprises a plurality of idle context blocks, wherein each idle context block is stored in a chain mode in a specified direction, and the idle context unidirectional link list is obtained. Specifically, the target idle context block is obtained from an idle context list of the tightly coupled memory, wherein the target idle context block can be a head idle context block in the idle context list, can also be any idle context block in the idle context list, or can be a target idle context block which is determined to be matched from the idle context list according to actual service requirements, actual product requirements or actual application scenes.
And step 106, when the execution message context is not abnormal, writing the necessary data of the input/output channel into the target idle context block.
Specifically, when the execution message context is not abnormal after the target idle context block is determined, for example, the execution message context can respond within a preset time or the execution message context is not abnormal in data state, etc., which can be determined as the execution message context is not abnormal. Further, the necessary data of the input/output access channels in the message context can be written into the target idle context block in the tightly coupled memory, not the whole message context is written into the tightly coupled memory, but when the exception does not occur in the execution message context, the necessary data of the input/output access channels with frequent access frequency in the message context is written into the tightly coupled memory, so that the use efficiency of the Tightly Coupled Memory (TCM) is improved, and the required space of the TCM is greatly reduced.
Step 108, when the context of the execution message is abnormal, the unnecessary data of the input/output channel is written into the dynamic random access memory.
Wherein, when an abnormality occurs in the execution message context, for example, the execution message context does not respond within a preset time or feedback is not received within a preset time, or an abnormality occurs in a data state when the message context is executed, etc., it may be determined that an abnormality occurs in the execution message context. Further, unnecessary data of the input/output channel in the message context is acquired, and the unnecessary data of the input/output channel is written into the dynamic random access memory. Among them, the dynamic random access memory (Dynamic Random Access Memory, DRAM) is a semiconductor memory, and the main principle of the function is to use the magnitude of the stored charge in the capacitor to represent whether a binary bit (bit) is 1 or 0.
In one embodiment of the present application, the read/write rate of the tightly coupled memory is higher than the read/write rate of the dynamic random access memory.
The access speed of the CPU is different, the closer to the CPU, the higher the speed is, the closest to the CPU is, and the farthest is the dynamic random access memory, so the read-write speed of the close coupling memory is higher than that of the dynamic random access memory.
Therefore, when the message context is executed, if no abnormality occurs, the data with high access frequency on the input/output path is stored in the tightly coupled memory with highest read-write rate, so that the efficiency of subsequent data access is improved, and if the abnormality occurs on the message context, the data with low access frequency on the input/output path is stored in the dynamic random access memory with slower read-write rate, so that the message context is classified, the use efficiency of the high-speed storage TCM is improved, and the required space of the TCM is halved.
In the above method for processing a message context, the message context is classified into data necessary for an input/output path and data unnecessary for the input/output path, and when no abnormality occurs in the execution message context, the data necessary for the input/output path is written into the tightly coupled memory, and when abnormality occurs in the execution message context, the data unnecessary for the input/output path is written into the dynamic random access memory. By classifying the message contexts, only the data which must be accessed on the input/output channels are stored in the close-coupled memory, so that the use efficiency of the close-coupled memory is improved, the whole message context is not required to be stored in the close-coupled memory, the use of the close-coupled memory is saved, the number of available message contexts is improved, and the processing efficiency of the message contexts is improved.
In one embodiment of the present application, receiving a message context includes: and receiving a message command sent by the computer equipment, wherein the computer equipment is a terminal or a server, and analyzing the message command to obtain a corresponding message context, and the message context is command descriptive information corresponding to the message command.

Specifically, the solid state disk is connected with a computer device, and the computer device can be a terminal or a server, receives a message command sent by the computer device, analyzes the message command to obtain various descriptive information corresponding to the message command, and obtains a corresponding message context. Various descriptive information corresponding to the message command includes, but is not limited to, message command type, message source core, whether the message has timed out, etc. That is, the message context is various command descriptive information describing the message command.

Before the target idle context block is acquired from the idle context unidirectional link list of the tightly coupled memory, the idle context unidirectional link list can be established through the byte size of the message context. Specifically, the byte size corresponding to the message context is obtained, the byte size is a measurement unit for describing the message context, the size of each free context block is determined in the tightly coupled memory according to the byte size, and then chain storage is carried out on each free context block in a specified direction, so that a free context unidirectional linked list is obtained. Wherein each free context block is associated with a corresponding address.
In one embodiment of the present application, establishing a free context list in a tightly coupled memory according to byte size includes: and partitioning the tightly coupled memory according to the byte size to obtain a plurality of idle context blocks, and storing each idle context block in a chained mode to obtain an idle context unidirectional link list.
Specifically, after obtaining the byte size corresponding to the message context, the tightly coupled memory is partitioned according to the byte size corresponding to the message mountain context, and specifically, the block size of each free context block is the same as the byte size, so as to obtain a plurality of free context blocks. Further, each free context block is stored in a chained mode according to the appointed direction, and a free context unidirectional linked list is obtained.
In one embodiment of the present application, obtaining a target idle context block from an idle context list of a tightly coupled memory includes: the target idle context block is obtained from the idle context list header.
Specifically, the idle context unidirectional link list includes a plurality of idle context blocks, and the target idle context block for writing the necessary data of the input/output path can be obtained from the head of the idle context unidirectional link list, and can be the head idle context block of the idle context unidirectional link list. That is, the target free context block may be obtained from the head of the free context list, and each head free context block may be used to write the i/o path necessary data, and is determined as the target free context block.
In one embodiment of the present application, writing input-output path necessary data to a target free context block includes: and acquiring a preset message format, and writing the necessary data of the input/output channel into a data field in the target idle context block according to the preset message format.
The preset message format may be predetermined according to an actual service requirement, an actual product requirement or an actual application scene, and may be a standard format for writing data in the target idle context block. Specifically, a preset message format is obtained, and the necessary data of the input/output channel is written into the data field in the target idle context block according to the preset message format. The target free context block may be divided into a data field and a pointer field, the data field may be used to store the necessary data of the input/output path, and the pointer field may be used to store an address corresponding to the free context block. That is, each free context block in the free context list corresponds to an address, and is stored in a pointer field corresponding to each free context block.
In one embodiment of the present application, after writing the input/output path necessary data to the target idle context block, the method further includes: deleting the written context block from the idle context list, acquiring the message type from the message context, and loading the written context block into the corresponding functional unit according to the message type.
After the necessary data of the input/output channel is successfully written into the target idle context block, the written context block is removed from the idle context unidirectional link list, and the written context block is mounted into a corresponding functional unit (Logical Unit Number, abbreviated as LUN) according to the message type in the message context.
Specifically, after the necessary data of the input/output channel is successfully written into the target idle context block, the written context block is deleted from the idle context list, the message type is obtained from the message context, and the written context block is mounted in the corresponding functional unit.
In one embodiment of the present application, the method further includes: and loading the functional unit in a channel linked list, and issuing the written context blocks to the flash memory so that the flash memory processes the written context blocks.

Further, the emptied context block is re-hung at the tail of the idle context list. That is, after the flash memory processes the written context block, a completion message is returned, the written context block is emptied according to the completion message, and the written context block is changed back to the idle context block again, and is returned to the idle context list, and is hung at the tail of the idle context list.
