| Abstract: | This paper proposed a NVMe driver design scheme based on user-level,and a device could provide storage functions for multiple storage processes.The VFIO module of IOMMU function was used to implement the user's register operation and the DMA function.The paper gave the overall scheme of the driver design and the technical details of the implementation.Compared with the other schemes,the proposed scheme has low reliance on hardware and is easy to expand. |
