net/mlx5: Refactor mlx5_core_mr to mkey

2016-03-01T16:18:37+00:00

Mlx5's mkey mechanism is also used for memory windows.
The current code base uses MR (memory region) naming, which is
inaccurate. Changing MR to mkey in order to represent its different
usages more accurately.

IB/mlx5: Add support for setting source QP number

2016-03-01T16:02:05+00:00

In order to create multiple GSI QPs, we need to set the source QP number to
one on all these QPs. Add the necessary definitions and infrastructure to
do that.

{IB, net}/mlx5: Move the modify QP operation table to mlx5_ib

2016-01-21T17:01:09+00:00

When modifying a QP, the desired operation was determined in
the mlx5_core using a transition table that takes the current
state, the final state, and returns the desired operation.

Since this logic will be used for Raw Packet QP, move the
operation table to the mlx5_ib.

IB/mlx5: Add Raw Packet QP query functionality

2016-01-21T17:01:09+00:00

Since Raw Packet QP is composed of RQ and SQ, the IB QP's
state is derived from the sub-objects. Therefore we need
to query each one of the sub-objects, and decide on the
IB QP's state.

net/mlx5_core: Add RQ and SQ event handling

2016-01-21T17:01:09+00:00

RQ/SQ will be used to implement IB verbs QPs, so the IB QP affiliated
events are affiliated also with SQs and RQs.

Since SQ, RQ and QP resource numbers do not share the same name
space, a queue type field was added to the event data to specify
the SW object that the event is affiliated with.

IB/mlx5: Add driver cross-channel support

2015-12-24T04:33:14+00:00

Add support of cross-channel functionality to mlx5
driver. This includes ability to ignore overrun for CQ
which intended for cross-channel, export device capability and
configure the QP to be sync master/slave queues.

The cross-channel enabled QP supports combination of
three possible properties:
* WQE processing on the receive queue of this QP
* WQE processing on the send queue of this QP
* WQE are supported on the send queue

net/mlx5_core: HW data structs/types definitions cleanup

2015-05-31T01:23:11+00:00

mlx5_ifc.h was heavily modified here since it is now generated by a
script from the device specification (PRM rev 0.25). This specification
is backward compatible to existing hardware.

Some structures/fields were added here in order to enable the Ethernet
functionality of the driver.

This patch implement a page fault handler (leaving the pages pinned as
of time being).  The page fault handler handles initiator and responder
page faults for UD/RC transports, for send/receive operations, as well
as RDMA read/write initiator support.
