2017-08-22IB/rdmavt, hfi1, qib: Modify check_ah() to account for extended LIDsDon Hiatt1-0/+9
rvt_check_ah() delegates lid verification to underlying driver.

2017-05-01IB/core: Define 'ib' and 'roce' rdma_ah_attr typesDasaratharaman Chandramouli1-0/+2
rdma_ah_attr can now be either ib or roce allowing core components to use one type or the other and also to define attributes unique to a specific type. struct ib_ah is also initialized with the type when its first created. This ensures that calls such as modify_ah dont modify the type of the address handle attribute.

2017-04-05IB/rdmavt, IB/hfi1, IB/qib: Make wc opcode translation driver dependentMike Marciniszyn1-0/+13
The work to create a completion helper moved the translation of send wqe operations to completion opcodes to rdmvat. This precludes having driver dependent operations. Make the translation driver dependent by doing the translation in the driver prior to the rvt_qp_swqe_complete() call using restored translation tables.

2017-02-14IB: Query ports via the core instead of direct into the driverOr Gerlitz1-0/+1
Change the drivers to call ib_query_port in their get port immutable handler instead of their own query port handler. Doing this required to set the core cap flags of this device before the ib_query_port call is made, since the IB core might need these caps to serve the port query. Drivers are ensured by the IB core that the port attributes passed to the port query verb implementation are zero, and hence we removed the zeroing from the drivers. This patch doesn't add any new functionality.

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.

2016-03-10IB/qib: Remove ibport and use rdmavt versionHarish Chegondi1-26/+26
Remove several ibport members from qib and use the rdmavt version. rc_acks, rc_qacks, and rc_delayed_comp are defined as per CPU variables in rdmavt. Add support for these rdmavt per CPU variables which were not per cpu variables in qib ibport structure.

2016-03-10IB/qib: Remove qp and mr functionality from qibDennis Dalessandro1-105/+71
Remove qp and mr support from qib and use rdmavt. These two changes cannot be reasonably be split apart into separate patches because they depend on each other in mulitple places. This paves the way to remove even more functions in subsequent patches.

2016-03-10IB/qib: Remove driver specific members from qib qp typeDennis Dalessandro1-22/+39
In preparation for moving the queue pair data structure to rdmavt the members of the driver specific queue pairs which are not common need to be pushed off to a private driver structure. This structure will be available in the queue pair once moved to rdmavt as a void pointer. This patch while not adding a lot of value in and of itself is a prerequisite to move the queue pair out of the drivers and into rdmavt. The driver specific, private queue pair data structure should condense as more of the send side code moves to rdmavt.
