* RDMA/cma: Add multicast communication supportSean Hefty2007-02-16
| | | | | | | | | | | | | | | | | | | | Extend rdma_cm to support multicast communication. Multicast support is added to the existing RDMA_PS_UDP port space, as well as a new RDMA_PS_IPOIB port space. The latter port space allows joining the multicast groups used by IPoIB, which enables offloading IPoIB traffic to a separate QP. The port space determines the signature used in the MGID when joining the group. The newly added RDMA_PS_IPOIB also allows for unicast operations, similar to RDMA_PS_UDP. Supporting the RDMA_PS_IPOIB requires changing how UD QPs are initialized, since we can no longer assume that the qkey is constant. This requires saving the Q_Key to use when attaching to a device, so that it is available when creating the QP. The Q_Key information is exported to the user through the existing rdma_init_qp_attr() interface. Multicast support is also exported to userspace through the rdma_ucm.

* IB/sa: Track multicast join/leave requestsSean Hefty2007-02-16
| | | | | | | | | | | | | | | | The IB SA tracks multicast join/leave requests on a per port basis and does not do any reference counting: if two users of the same port join the same group, and one leaves that group, then the SA will remove the port from the group even though there is one user who wants to stay a member left. Therefore, in order to support multiple users of the same multicast group from the same port, we need to perform reference counting locally. To do this, add an multicast submodule to ib_sa to perform reference counting of multicast join/leave operations. Modify ib_ipoib (the only in-kernel user of multicast) to use the new interface.

* IB: Make sure struct ib_user_mad.data is alignedJason Gunthorpe2007-02-04
| | | | | | | | | | | Make the untyped data region in ib_user_mad have type u64 so that it gets aligned properly. This avoids alignment faults in ib_umad when casting the data field to an rmpp_mad and accessing the 64-bit tid field on architectures like ia64.

* IB: Return qp pointer as part of ib_wcMichael S. Tsirkin2007-02-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | struct ib_wc currently only includes the local QP number: this matches the IB spec, but seems mostly useless. The following patch replaces this with the pointer to qp itself, and updates all low level drivers and all users. This has the following advantages: - Ability to get a per-qp context through wc->qp->qp_context - Existing drivers already have the qp pointer ready in poll cq, so this change actually saves a tiny bit (extra memory read) on data path (for ehca it would actually be expensive to find the QP pointer when polling a CQ, but ehca does not support SRQ so we can leave wc->qp as NULL for ehca) - Users that need the QP number can still get it through wc->qp->qp_num Use case: In IPoIB connected mode code, I have a common CQ shared by multiple QPs. To track connection usage, I need a way to get at some per-QP context upon the completion, and I would like to avoid allocating context object per work request just to stick a QP pointer into it. With this code, I can just use wc->qp->qp_context. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

* IB: Fix ib_dma_alloc_coherent() wrapperRoland Dreier2006-12-15
| | | | | | | | | | | The ib_dma_alloc_coherent() wrapper uses a u64* for the dma_handle parameter, unlike dma_alloc_coherent, which uses dma_addr_t*. This means that we need a temporary variable to handle the case when ib_dma_alloc_coherent() just falls through directly to dma_alloc_coherent() on architectures where sizeof u64 != sizeof dma_addr_t.

| | | | | | | | | | | | | | | The ib_cm_establish() function is replaced with a more generic ib_cm_notify(). This routine is used to notify the CM that failover has occurred, so that future CM messages (LAP, DREQ) reach the remote CM. (Currently, we continue to use the original path) This bumps the userspace CM ABI. New alternate path information is captured when a LAP message is sent or received.

* | IB/uverbs: Don't serialize with ib_uverbs_idr_mutexRoland Dreier2006-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, all userspace verbs operations that call into the kernel are serialized by ib_uverbs_idr_mutex. This can be a scalability issue for some workloads, especially for devices driven by the ipath driver, which needs to call into the kernel even for datapath operations. Fix this by adding reference counts to the userspace objects, and then converting ib_uverbs_idr_mutex into a spinlock that only protects the idrs long enough to take a reference on the object being looked up. Because remove operations may fail, we have to do a slightly funky two-step deletion, which is described in the comments at the top of uverbs_cmd.c. This also still leaves ib_uverbs_idr_lock as a single lock that is possibly subject to contention. However, the lock hold time will only be a single idr operation, so multiple threads should still be able to make progress, even if ib_uverbs_idr_lock is being ping-ponged. Surprisingly, these changes even shrink the object code: add/remove: 23/5 grow/shrink: 4/21 up/down: 633/-693 (-60) Signed-off-by: Roland Dreier <rolandd@cisco.com>
