All responder errors from request packets that do not consume a receive WQE fail to generate acks for RC QPs. This patch corrects this behavior by making the flow follow the same path as request packets that do consume a WQE after the completion.

Local invalidate is also a kind of memory management operation, not only memory bind operation. Furthermore, as invalidate operations include local and remote, add prefix to the prompt message to make it clearer.

To update xlt (during mlx5_ib_reg_user_mr()), the driver can request up to 1 MB (order-8) memory, depending on the size of the MR. This costly allocation can sometimes take very long to return (a few seconds). This causes the calling application to hang for a long time, especially when the system is fragmented. To avoid these long latency spikes, the calls the higher order allocations need to fail faster in case they are not available. In order to acheive this we need __GFP_NORETRY flag in the gfp_mask before during fetching the free pages. Allow the algorithm to automatically fall back to smaller page sizes.

The code currently assumes that the mmu_notifier struct embedded in mmu_rb_handler only contains two fields. There are now extra fields: struct mmu_notifier { struct hlist_node hlist; const struct mmu_notifier_ops *ops; struct mm_struct *mm; struct rcu_head rcu; unsigned int users; }; Given that there in no init for the mmu_notifier, a kzalloc() should be used to insure that any newly added fields are given a predictable initial value of zero.

The current rdma_netdev handling in ipoib hooks the tx_timeout handler, but prints out a totally useless message that prevents effective debugging especially when multiple transmit queues are being used. Add a tx_timeout rdma_netdev hook and implement the callback in the hfi1 to print additional information. The existing non-helpful message is avoided when the driver has presented a callback.

HIP08 supports both normal and record doorbell mode for RQ and CQ, SQ record doorbell for userspace is also supported by the software for flushing CQE process. As now the capability of HIP08 are exposed to the user and are configurable, the support of normal doorbell should be added back. Note that, if switching to normal doorbell, the kernel will report "flush cqe is unsupported" if modify qp to error status as the flush is based on record doorbell.

On RoCE systems, a CM REQ contains a Primary Hop Limit > 1 and Primary Subnet Local is zero. In cm_req_handler(), the cm_process_routed_req() function is called. Since the Primary Subnet Local value is zero in the request, and since this is RoCE (Primary Local LID is permissive), the following statement will be executed: IBA_SET(CM_REQ_PRIMARY_SL, req_msg, wc->sl); This corrupts SL in req_msg if it was different from zero. In other words, a request to setup a connection using an SL != zero, will not be honored, and a connection using SL zero will be created instead. Fixed by not calling cm_process_routed_req() on RoCE systems, the cm_process_route_req() is only for IB anyhow.

In the original rxe implementation it was intended to use a common object to represent MRs and MWs but they are different enough to separate these into two objects. This allows replacing the mem name with mr for MRs which is more consistent with the style for the other objects and less likely to be confusing. This is a long patch that mostly changes mem to mr where it makes sense and adds a new rxe_mw struct. Link: https://lore.kernel.org/r/20210325212425.2792-1-rpearson@hpe.comSigned-off-by:
