Abstract

The invention relates to a drive test method and system, and the method comprises the steps: calling a standardized Verbs interface, creating a protection domain, registering a memory space, creating a completion queue and a queue pair, initializing the queue pair, modifying the state of the queue pair into a ready state, submitting a work request, starting data transmission, and carrying out the polling of the completion queue. According to the method and the device, the work request is acquired and processed to obtain and process the completion event of the work request, so that the basic function of the RDMA driver is realized, a uniform API interface is provided for the RDMA driver verification test in a DSP bare core simulation environment, the development of the API of the RDMA driver of a specific version for different simulation platforms is avoided, the development difficulty of the RDMA driver is remarkably reduced, and the flexibility of cross-platform transplantation of the RDMA driver is improved.
