Query gid is in rdmavt, but still relies on the driver to maintain the guid table. Add the necessary driver call back and remove the existing verb handler. 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:

rvt_query_port calls into the driver through a call back function query_port_state to populate the rest of ib_port_attr elements. rvt_modify_port calls into the driver if needed through a call back function shut_down_port() Signed-off-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:

Low level drivers need to be able to check incoming attributes as well as be able to adjust their private data on queue pair modification. Add 2 driver callbacks, check_modify_qp and modify_qp, to facilitate this. Signed-off-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:

Add in a post_send and post_one_send to rdmavt. The ULP will provide a WQE to rdmavt which will then walk and queue each element. Rdmavt will then queue the work to be done in the driver or kick the driver's progress routine. There needs to be a follow on patch which adds in another lock for the head of the queue so that it can be added to and read from in parallel. This will touch protocol handlers and require other changes in the drivers. This will be done separately. Reviewed-by:
