Hi, all I am debugging for XRC feature on hns roce and have a question for help. I am use perftest tool. use the cmd as follows: server: ./ib_send_bw -n 5 -c XRC client: ./ib_send_bw -n 5 -c XRC ip when run into the ctx_xrc_srq_create interface, it will call ibv_create_srq_ex function and enter into the libibverbs library. However, the ibv_create_srq_ex will not be entered in verbs.h I doubt that I have an incorrect configurtion for using uapi xx_xx_ex. others may give some help for me. note: My rdma-core version is rdma-core-v15. thanks Lijun Ou -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
