Referring to fig. 1, a flowchart illustrating steps of a disk management method according to an embodiment of the present application is shown, where, as shown in fig. 1, the disk management method may include: step 101, step 102, step 103 and step 104.
Step 101: and acquiring preset operation for the disk file, which is sent by the appointed application program.
The embodiment of the application can be applied to the first processor which is not provided with the UFS storage device, namely the execution main body is the first processor. In this example, the first processor may be, but is not limited to, a CP core.
In this embodiment, the CP core is used as a first processor, and the AP core is used as a second processor to describe the technical solution of the embodiment of the present application as follows.
The embodiment of the application can enable the processor which is not provided with the UFS storage device to use the disk file system by adopting the virtualized disk technology and the technology of disk device simulation.
In order to achieve the purpose, the embodiment of the application provides a heterogeneous virtual disk system. As shown in fig. 2, the heterogeneous virtual disk system may include: CP (Cluster Processor), AP (Application Processor) and UFS (UNIX file system).
The CP side may include a plurality of modules, respectively: VFS, EXT4, BK1, and RPMSG, wherein,
VFS (virtual file system) is an abstraction of a physical file system so that different layouts of physical file systems can operate on top of them using the same interface.
EXT4 (the specific file system) is responsible for interfacing to the physical disk partition, mapping the file system level offset to the disk blocks of the physical disk, and for implementation of common operations of the file system, such as opening closed files, reading and writing files, etc.
The BLK1 module can realize the semantics of the virtual disk, upwards receives the block device request of the EXT4 module, downwards sends the request to the RPMSG module, and receives the response of the operation.
The RPMSG module encapsulates the capability of the MAILBOX and Shared Memory, providing an efficient transport channel.
The AP side also includes a plurality of modules, respectively: BLK2, RPMSG, device Model, VFS/EXT4, UFS Driver, wherein,
the RPMSG module encapsulates the capability of the MAILBOX and Shared Memory, providing an efficient transmission channel.
The BLK2 module corresponds to the BLK1 module function on the CP side.
Device Model (Device Model module) encapsulates a disk Device Model, which acts as a conversion intermediary for disk read/write block devices and local disk mirroring
The VFS/EXT4 (file system module) accesses the disk node of the local file mirror image to directly read and write the block device.
The UFS device Driver (i.e., UFS Driver) may receive a read/write request from the disk block device, and operate a specific UFS or SSD device to obtain a result.
The UFS device is a FLASH storage device.
In a specific implementation, when an operation (such as a data read/write operation, etc.) needs to be performed by a specified application program (such as a meter, HUD, etc.), a preset operation for a disk file sent by the specified application program may be acquired. The preset operation may be a data read operation, a data write operation, or the like, and in particular, a specific type of the preset operation is not limited.
In practical application, the appointed application program can call the VFS of the CP side to initiate the operation for the disk file, and then can call the EXT4 module of the CP side to obtain the preset operation. This implementation may be described in detail below in conjunction with fig. 3.
Referring to fig. 3, a step flowchart of a preset operation conversion method provided by an embodiment of the present application is shown. As shown in fig. 3, the preset operation switching method may include: step 301 and step 302.
Step 301: and acquiring a first VFS module of the first processor, which is called by the appointed application program, and initiating the operation aiming at the disk file.
In the embodiment of the application, the appointed application program can call the first VFS module of the CP core to initiate the operation aiming at the disk file. Such as an application calling the VFS of the CP core to initiate operations to read or write a file, etc.
Step 302 is performed after obtaining an operation for a disk file initiated by a first VFS module that invokes a first processor by a specified application.
Step 302: and calling a first EXT4 module of the first processor to convert the operation into the preset operation according to the offset of the disk file, and sending a request message corresponding to the preset operation to a first transfer module of the first processor.
After the operation for the disk file initiated by the first VFS module of the CP core called by the specified application program is obtained, the first EXT4 module of the CP core may be called to convert the operation into a preset operation according to the offset of the disk file, and a request message corresponding to the preset operation is sent to the first transfer module of the CP core. For example, the application calls VFS to read the file, VFS calls the actual file system EXT4 to complete the read operation, the EXT4 module translates the operation of reading the file into the operation of reading the BLOCK, initiates a request to BLK1 through the BLOCK layer, and so on.
According to the embodiment of the application, the transfer module is added in the first processor, and can map the offset of the file system level to the disk block of the physical disk according to the offset of the disk file, so that the AP core can be conveniently instructed to execute corresponding operation according to the disk block.
After acquiring the preset operation for the disk file sent by the specified application program, step 102 is executed.
Step 102: and converting the preset operation into an RPMSG request message.

After the preset operation for the disk file sent by the specified application program is acquired, the preset operation may be converted into an RPMSG request message. Specifically, after sending the request to BLK1, BLK1 may send the RPMSG module an RPMSG message to package the request. This implementation may be described in detail in connection with fig. 4.

Step 401: and calling the first transfer module to carry out packaging processing on the request message to obtain the RPMSG request message, and sending the RPMSG request message to the first RPMSG module.

The RPMSG request message may then be sent to the first RPMSG module.
The embodiment of the application converts the request message into the RPMSG request message through the transfer module at the CP side, thereby being convenient for the RPMSG module to identify the request message.
After converting the preset operation into the RPMSG request message, step 103 is performed.
Step 103: and calling a first RPMSG module of the first processor to store the RPMSG request message in the inter-core shared memory.
After converting the preset operation into the RPMSG request message, the first RPMSG module of the CP core may be called to store the RPMSG request message in the inter-core shared memory after converting the preset operation into the RPMSG request message. Specifically, the capability of the MAILBOX is encapsulated in the first RPMSG module, and the RPMSG request message can be stored in the inter-core shared memory through the capability.
After the first RPMSG module of the first processor is invoked to store the RPMSG request message in the inter-core shared memory, step 104 is performed.
Step 104: and sending an interrupt message to a second RPMSG module of a second processor provided with the UFS storage device, so that the second RPMSG module responds to the interrupt message, acquires the RPMSG request message from the inter-core shared memory, and executes the preset operation on the disk file system corresponding to the first processor according to the RPMSG request message by the second processor.
After the first RPMSG module of the CP core is called to store the RPMSG request message in the inter-core shared memory, an interrupt message may be sent to the second RPMSG module of the AP core, so that the second RPMSG module may respond to the interrupt message to obtain the RPMSG request message from the inter-core shared memory, and the AP core may execute a preset operation on the disk file system corresponding to the CP core according to the RPMSG request message.
In practical application, a disc block corresponding to the CP check may be reserved on the physical disc, and EXT4 may map the offset to the disc block of the physical disc, so as to initiate a request, and instruct the AP to check the corresponding disc block to execute the corresponding operation.
According to the mode provided by the embodiment of the application, the RPMSG modules are added on the CP side and the AP side, and a mechanism of interrupting and sharing the memory is adopted, so that the CP side can perform unified and efficient management of the disk file system, the utilization rate of the memory of the CP side operating system is improved, and the file storage function is increased.
