Hi,
maybe i misread your last email - are you trying to use reg_user_mr() as a kernel client? If yes - that will not work. You should use the interface as described by Wendy (get_dma_mr() etc.), since you are dealing with kernel memory. I can add a check to siw to prevent that call into siw_reg_user_mr() to be executed for kernel clients. thanks, Bernard.
We are working to create a RDMA client within the kernel which will connect to a working RDMA userspace server. We are using the userspace code for testing purpose , in the final version all the communication will be done within the kernel space.
