The user mode partition is that all exe and dynamic link libraries in the Windows operating system are loaded to the area, and simultaneously, the accessible resources of the process are loaded to the area. The purpose of the 64k exclusion partition is to isolate the user mode partition from the kernel mode partition, preventing the user program from crossing into the kernel space. Kernel mode partitioning is where the code for the operating system resides; the code for the threads, memory management, file system, network support, and driver related programs is loaded into this area, and this portion of the code is common to all processes. In the embodiment of the present application, the virtual address space may be mapped to the physical address space for access by writing a kernel driver in a kernel mode partition. Specifically, after the physical address of the DIO interface is obtained, the system of the electronic device may take the physical address of the DIO interface as a virtual memory address, and at this time, the virtual memory address may be directly changed.
Step S152: and changing the virtual memory address according to the mapping relation between the state information configured for the DIO interface, the preset state information and the address information.
Step S153: and calling a kernel driver to change the physical address of the DIO interface according to the changed virtual memory address and the mapping relation between the preset virtual memory address and the physical address of the DIO interface.
Specifically, a kernel driver is loaded by calling a function ZwMapViewOfSection () provided in a system core file ntdll, and the kernel driver is notified of which specific virtual memory address the mapped address is, so as to establish mapping between the virtual memory address and the physical address of the DIO interface, thereby realizing the change of the physical address of the DIO interface.
According to the method and the device, the preset mapping relation between the state information and the address information and the mapping relation between the preset virtual memory address and the physical address of the DIO interface are used, so that the state information of the DIO interface is configured on the DIO interface configuration interface, the physical address of the DIO interface can be configured, and the configuration of the DIO interface is rapidly realized.
Referring to FIG. 8, in one embodiment, the address information includes address bits to be changed and values corresponding to the address bits; in step S152, the changing the virtual memory address according to the mapping relationship between the state information configured for the DIO interface, the preset state information, and the address information includes:
step S1521: and determining the address bit of the virtual memory address to be changed and the value on the corresponding address bit according to the state information configured on the DIO interface and the mapping relation between the preset state information and the address information.
For the state of the DIO interface, the state change can be realized only according to the Value of the motherboard model on some address BITs, for example, for the motherboard with the model of CIS-RKBU-LW01, if the DIO interface is to be changed to the input state, the Value of the address BITs of the 0 th BIT, the 1 st BIT, the 8 th BIT and the 9 th BIT of the DIO interface is only changed to x, x, 1,0, that is, BIT [9,8,1,0] is changed to Value [0,1, x, x ], and the DIO interface can be changed to the input loading.
Step S1522: and changing the virtual memory address according to the address bits of the virtual memory address to be changed and the values on the corresponding address bits.
According to the embodiment of the application, the address can be automatically changed according to the state information configured for the DIO interface through the preset mapping relation between the state information and the address information.
In an embodiment, the DIO interface configuration method based on the Windows system may further include the following steps:
step S160: calling a kernel driver to read the configured physical address of the DIO interface;
step S170: acquiring the state information of the DIO interface according to the physical address of the DIO interface and the mapping relation between the preset state information and the address information;
step S180: and displaying the identification information of the DIO interface and the state information of the DIO interface on the main control equipment.
After the display is finished, the kernel driver is cancelled and loaded through ZwUnmapViewOfSection (), so that the memory occupation is reduced.
Referring to fig. 9, after the DIO Port1 is input in the DIO interface id input box and the output high level state trigger button is clicked to complete the configuration of the DIO Port1, the DIO Port1 configuration success and the current state of the DIO Port1 are fed back to the DIO configuration interface.
According to the method and the device, the state information of the DIO interface is fed back by reading the physical address of the DIO interface after configuration, so that a user can learn the configuration condition of the DIO interface in real time.
