* IB/qib: Setup notify free/create mad agent callbacks for rdmavtDennis Dalessandro2016-03-111-0/+4
| | | | | | | | | | | 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 Marciniszyn2016-03-111-9/+28
| | | | | | | | | | | | | | | | | | | | | 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.

The per port core capability flags to be added later are also immutable data to be stored in the ib_device object. In preparation for this create a structure for per port immutable data and place the pkey and gid table lengths within this structure. "get_port_immutable" is added as a mandatory device function to allow the drivers to fill in this data.
