The completion ring for tx is using the wrong size to size the ring, oversizing the ring by two orders of magniture. Correct the allocation size and use kcalloc_node() to allocate the ring.

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.

The doorbell update interfaces are very similar for different queues, such as SQ, RQ, SRQ, CQ and EQ. So reorganize these code and also fix some inappropriate naming. Link: https://lore.kernel.org/r/1616840738-7866-3-git-send-email-liweihang@huawei.comSigned-off-by:

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:

Initial drop action support missed that drop action can be added to egress flow tables as well. Add the missing support. This requires making sure that dest_type isn't set to PORT which in turn exposes a possibility of passing dst while indicating number of dsts as zero.

When the L2 driver detects a device crash or device undergone reset, it invokes a stop callback to recover from error. The current RoCE driver doesn't recover the device. So move the device to error state and dispatch fatal events to all qps Release the MSIx vectors to avoid a crash when L2 driver disables the MSIx. Also, check for the device state to avoid posting further commands to the HW. Link: https://lore.kernel.org/r/1615968942-30970-1-git-send-email-selvin.xavier@broadcom.comSigned-off-by:

Current code uses many different types when dealing with a port of a RDMA device: u8, unsigned int and u32. Switch to u32 to clean up the logic. This allows us to make (at least) the core view consistent and use the same type. Unfortunately not all places can be converted. Many uverbs functions expect port to be u8 so keep those places in order not to break UAPIs. HW/Spec defined values must also not be changed. With the switch to u32 we now can support devices with more than 255 ports. U32_MAX is reserved to make control logic a bit easier to deal with. As a device with U32_MAX ports probably isn't going to happen any time soon this seems like a non issue. When a device with more than 255 ports is created uverbs will report the RDMA device as having 255 ports as this is the max currently supported. The verbs interface is not changed yet because the IBTA spec limits the port size in too many places to be u8 and all applications that relies in verbs won't be able to cope with this change. At this stage, we are extending the interfaces that are using vendor channel solely Once the limitation is lifted mlx5 in switchdev mode will be able to have thousands of SFs created by the device. As the only instance of an RDMA device that reports more than 255 ports will be a representor device and it exposes itself as a RAW Ethernet only device CM/MAD/IPoIB and other ULPs aren't effected by this change and their sysfs/interfaces that are exposes to userspace can remain unchanged.
