setting responder_resources and initiator_depth

Hi all,

Currently, the RDS code sets both of these to 1 when calling rdma_accept(). Using an arbitrary greater value (e.g. 64) doesn't seem to work right.

I can call ib_query_qp(). Am I to assume I can set initiator_depth up to ib_qp_attr.max_rd_atomic, and responder_resources to ib_qp_attr.max_dest_rd_atomic and this will work?

Thanks -- Regards -- Andy

You need to coordinate the values with those supported by the remote end of the connection. See the rdma_connect and rdma_accept man pages for additional details. The librdmacm has checks in rdma_connect and rdma_accept to verify that the values provided by the user at least make sense for the local HW.
