Technical Field
The field relates to the field of computers, and more particularly to a method, an apparatus, a device and a readable medium for filling a dummy in a solid state disk.
Background
In the process of writing data, the solid state disk needs to be operated in multiple steps, and the writing data is written into the hardware unit, that is, the solid state storage unit, and the performance of writing data and the correctness of data are important characteristics of the solid state disk, so that the solid state disk has higher requirements on the process of writing data.
In the existing data writing process, not only the user data operation is performed, but also special processing needs to be performed on the solid state disk in order to ensure the storage security of the user, for example, operations of NAND filling dummy, and the like, and therefore, the performance and the data security of the solid state disk often need to be comprehensively considered. According to the transmission path of user data, the following steps are roughly divided: the operating system issues a write data instruction, the solid state disk moves data into the DDR after receiving the write instruction, then, available NAND physical addresses (PBAs) are obtained, and then, user data is written into NAND, etc., the inside of the solid state disk is often composed of a plurality of CPU cores, each CPU core is responsible for different tasks, the whole process of user data transfer is jointly completed by a plurality of CPUs in charge of different tasks, the CPU core that moves data to the DDR is referred to herein as the DM (data manager), the CPU core that obtains the available NAND physical address is referred to herein as the WM (write manager), the DM, upon receiving a write request, encapsulates the user data in the data structure of the CCB (cache control block), the CCB is sent to the WM, the WM receives the write request of the CCB by using the PCB (write control block), the WM then starts fetching the available NAND physical addresses and finally writes into the NAND, thus completing the data write operation.
The NAND is composed of a plurality of physical blocks (blocks), the blocks are composed of a plurality of PAGE, the NAND physical characteristics require that the unfilled blocks are filled when the power is cut off again, namely, 4 PAGEs of invalid data are written after the block of valid user data, so as to ensure the safety of NAND stored user data, the rationality and high efficiency of the dummy filling process can influence the power-down efficiency of the solid state disk, especially in abnormal situations, the electrical situation puts even higher demands on the dummy efficiency, since the allocation of NAND physical addresses is taken care of by WM, the following operation of the electrical filler dummy is also managed by the WM, the WM sends a dummy request to the DM, the DM organizes a dummy CCB to send a write request to the WM after receiving the dummy CCB, the WM writes the dummy CCB into the NAND according to a write flow, the WM releases the PCB and sends a dummy write completion back to the DM, and if the WM is not finished, the WM continues to initiate a dummy fill request to the DM, thus requiring the WM and DM to perform multiple information transfers.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
In view of the above object, a first aspect of the embodiments of the present invention provides an embodiment of a method for filling a solid state disk with dummy. Fig. 1 shows a schematic flow diagram of the method.
As shown in fig. 1, the method may include the steps of:
s1, in response to detecting the solid state disk is powered on, the data manager applies for a cache control block and stores dummy data in the applied cache control block.
In the power-on initialization stage of the solid state disk, a DM (data manager) initializes a professional CCB (cache control block) for filling dummy, the CCB is not used for other functions, a DDR address of the dummy data and the dummy data are specified in the CCB, and a WM (write manager) can sense the existence of the dummy data and can acquire the dummy data through the DDR address of the dummy data.
S2, responding to the solid state disk power-off detection, judging whether the solid state disk power-off is normal power-off or not.
The solid state disk power-off comprises power-off under normal conditions, namely normal shutdown, and power-off under abnormal conditions, wherein the time for power supply to fill in dummy data under the abnormal conditions is shorter, so that the dummy data needs to be less than that of the dummy data electrically filled under the normal conditions, and the dummy data can be filled in by incomplete blocks.
S3, in response to determining that the solid state disk is normally powered down, the write manager obtains dummy data stored in the requested cache control block and requests for a write control block.
S4, responding to the success of the write control block application, the write manager fills the acquired dummy data into the unfilled block.
When the dummy data needs to be filled, the WM needs to apply for a PCB (write control block), the source address and the address to be written of the dummy data are recorded in the write control block, PCB resources are released after the dummy data are successfully written, the PCB applied each time uses the same dummy data, namely, each block needing to be filled with the dummy data fills the same dummy data, and the NAND physical address needs to be applied for the PCB. When the power is normally off, each block needs to be filled with dummy data or dummy data of 4 PAGE, and at the moment, if the dummy data filled in the CCB once can not meet the requirement, the steps are circulated until the requirement is met. In some embodiments of the present invention, a write control block may be further reserved in the solid state disk, and the reserved write control block is only used when the user needs to fill dummy data when the user is powered off, so as to ensure that the user can successfully apply for the write control block each time when the user is powered off, so as to better improve the efficiency of filling dummy data when the user is powered off, and ensure the security of the user data stored in the solid state disk.
By the technical scheme, time loss caused by message transmission among modules can be reduced, internal resources of the write manager can be used to the maximum extent, dummy filling efficiency during power-off is greatly improved, and safety of user data stored in the solid state disk is guaranteed.
In a preferred embodiment of the present invention, the method further comprises:

and responding to the successful application of the write control block, and storing the source address of the dummy data and the address of the solid state disk to be written into the write control block.
In a preferred embodiment of the present invention, the method further comprises:
in response to a write control block application failure, a write control block is applied via the write manager every time a threshold time elapses until the application is successful. If the PCB application fails, the dummy data filling process is stopped, and the dummy data filling process is continued after the written PCB is released.
In a preferred embodiment of the present invention, the method further comprises:
in response to the fact that the solid state disk is abnormally powered off, the write manager obtains dummy data stored in the applied cache control block and applies for a write control block;
and responding to the successful application of the write control block, and filling half of the acquired dummy data into the unfilled block by the write manager. The time for filling the dummy data by power supply under the abnormal condition is shorter, so that the time is less than that of filling the dummy data by power supply under the normal condition, the dummy data can be filled in the unfilled blocks, and a small amount of dummy data can be filled in according to the needs.
According to the technical scheme, the CCB is pre-allocated by utilizing a symmetrical mechanism of the processor, the WM can sense the CCB, and the WM circularly sends the interior to fill dummy of the block to process without the participation of a DM module, so that the time loss caused by message transmission between the WM and the DM is reduced, the WM internal resource is used to the maximum extent, the dummy filling efficiency during power-off is greatly improved, and the safety of NAND storage user data is ensured.
