ibv_modify_qp ()函數會根據attr_mask遮罩,以attr參數中的屬性來修改 QPqp的屬性。attr參數是ibv_qp_attr結構,如<rdma/verbs.h>檔案中所定義。 struct ibv_qp_attr { enum ibv_qp_state qp_state; /* Move the QP to this state */ enum ibv_qp_state cur_qp_state; /* Assume this is the curre...
原文:ibv_modify_qp() - RDMAmojo RDMAmojo 描述 ibv_modify_qp()修改队列对的属性。 更改的属性描述了QP的发送和接收属性。在UC和RC QP中,这意味着将QP与远程QP连接。 在Infiniband中,其中一个应该执行到子网管理员(SA)的路径查询(one should perform path query to the Subnet Administrator (SA)),以便确...
