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. Reviewed-by:

Most functionality is still being done in the driver, set flags so that rdmavt will let hfi1 continue to handle mr, qp, and cq init. Reviewed-by:

This patch begins to make use of rdmavt by registering with it and providing access to the header files. This is just the beginning of rdmavt support in hfi1. Reviewed-by:

Add calls to rcu_read_lock()/rcu_read_unlock() as rvt_lookup_qpn callers must hold the rcu_read_lock before calling and keep the lock until the returned qp is no longer in use. Remove lookaside qp and some qp refcount atomics in the sdma send code that is redundant with the s_dma_busy refcount, which will also stall the state processing to the reset state. Change the qpn hash function to hash_32 which is hash function used in rvt_lookup_qpn. qpn_hash function would be eliminated in later patches. Reviewed-by:

Addin query gid support. Rdmavt still relies on the driver to maintain the gid table. Rdmavt simply calls into the driver to retrive the guid for a particular port. Reviewed-by:

IB core uses 1 relative indexing for ports. All of our data structures use 0 based indexing. Add an inline function that we can use whenever we need to validate a legal value and try to convert a port number to a port index at the entrance into rdmavt. Try to follow the policy that when we are talking about a port from IB core point of view we refer to it as a port number. When port is an index into our arrays refer to it as a port index.

This patch removes the post_send and post_one_send from the qib driver. The "posting" of sends will be done by rdmavt which will walk a WQE and queue work. This patch will still provide the capability to schedule that work as well as kick the progress. These are provided to the rdmavt layer. Reviewed-by:

This patch adds rdmavt device structure allocation in rdamvt. The ib_device alloc is now done in rdmavt instead of the driver. Drivers need to tell rdmavt the number of ports when calling. A side of effect of this patch is fixing a bug with port initialization where the device structure port array was allocated over top of an existing one. Reviewed-by:

This patch adds support of tracing events using the kernels built-in event tracing infrastructure. This can be extended to provide a wide range of trace and debug capabilities which have a negligible impact on performance when enabled. These should be preferred over the use of the rvt_pr* functions. Reviewed-by:
