| | | * | IB/qib,rdmavt: Move smi_ah to qibDennis Dalessandro2016-03-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rdmavt adopted an smi_ah from qib which is not needed by hfi1. Move this back to qib and get it out of the common library.

| | | * | IB/qib: Setup notify free/create mad agent callbacks for rdmavtDennis Dalessandro2016-03-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Qib needs to be notified when mad agents are created and freed, there is some counter maintenance that needs to be performed. Add those callbacks at registration time with rdmavt.

| | | * | IB/qib, staging/rdma/hfi1: add s_hlock for use in post sendMike Marciniszyn2016-03-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds an additional lock to reduce contention on the s_lock. This lock is used in post_send() so that the post_send is not serialized with the send engine and other send related processing. To do this the s_next_psn is now maintained on post_send() while post_send() related fields are moved to a new cache line. There is an s_avail maintained for the post_send() to mitigate trading cache lines with the send engine. The lock is released/acquired around releasing the just built packet to the egress mechanism.

This is just the beginning of rdmavt support in qib. Most functionality is still being done in the driver, set flags so that rdmavt will let qib continue to handle mr, qp, and cq init.

| | * | | IB/mlx5: Implement callbacks for manipulating VFsEli Cohen2016-03-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the IB defined callbacks used to manipulate the policy for the link state, set GUIDs or get statistics information. This functionality is added into a new file that will be used to add any SRIOV related functionality to the mlx5 IB layer. The following callbacks have been added: mlx5_ib_get_vf_config mlx5_ib_set_vf_link_state mlx5_ib_get_vf_stats mlx5_ib_set_vf_guid In addition, publish whether this device is based on a virtual function. In mlx5 supported devices, virtual functions are implemented as vHCAs. vHCAs have their own QP number space so it is possible that two vHCAs will use a QP with the same number at the same time.

| | * | | net/mlx5_core: Add VF param when querying vport counterEli Cohen2016-03-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a vf parameter to mlx5_core_query_vport_counter so we can call it to query counters of virtual functions. Also update current users of the API. PFs may call mlx5_core_query_vport_counter with other_vport set to indicate that they are querying a virtual function. The virtual function to be queried is given by the vf parameter. Virtual function numbering is zero based so the first VF is 0 and so on. When a PF queries its own function, the other_vport parameter is cleared.
