Address conversion method, device, electronic equipment and storage medium

Abstract

An embodiment of the present invention provides an address translation method, device, electronic equipment, and storage medium. The method includes: determining the address information to be translated according to the acquired translation instruction; and using the address association relationship according to the address information to be translated. The target address corresponding to the conversion instruction is obtained in the kernel; since the address association is based on the address information stored in the memory according to the preset write strategy in advance, the address information of the first array corresponding to the first type and the address information of the first array are generated. The mapping relationship between the address information of the second array corresponding to the second type, therefore, according to the address information to be converted determined by the conversion instruction, the mutual conversion between the target address and the address to be converted can be realized based on the address association relationship, and the operation It is simple and realizes the versatility on different operating systems, thereby improving the flexibility of the operating system.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an address conversion method, an address conversion device, an electronic device and a storage medium. Background technique [0002] At present, drivers using DMA (Chinese: direct memory access; English: Direct Memory Access) will communicate with hardware connected to the bus interface. Since the hardware uses physical addresses, the program code uses virtual addresses. Based on DMA The hardware of the system uses the bus address, that is, the DMA address, so a connection channel will be established between the DMA address and the physical address, so that the program code can access the DMA address by accessing the corresponding physical address. [0003] In the prior art, the conversion method between the DMA address and the physical address is a fixed script written into the kernel corresponding to different chips or bridges, and cannot be modified at will. The...

[0003] In the prior art, the conversion method between the DMA address and the physical address is a fixed script written into the kernel corresponding to different chips or bridges, which cannot be modified at will

Therefore, if there is a new conversion method, a corresponding new implementation method needs to be added to the kernel, so that the applicability of the operating system on other kernels cannot be realized; and every time a new conversion method appears, it needs to be implemented in the kernel. modification, complex operation
