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:

There are a number of minor things that should be set by rdmavt rather than by the drivers. Now that rdmavt has solidified in its design we can go ahead and clean up this stuff. Reviewed-by:

This patch adds the simple post receive verbs call to rdmavt. The actual interrupt handling and packet processing is still done in the low level driver. 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:

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:

Rely on rdmavt functions for creation of qp and qp table. Function to allocate a qpn is still being provided by qib as the algorithm to allocate a qpn in qib is different from that of the algorithm in rdmavt. Reviewed-by:

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. Reviewed-by:

The current code is problematic when the QP creation and ipoib is used to support NFS and NFS desires to do IO for paging purposes. In that case, the GFP_KERNEL allocation within create_qp causes a deadlock in tight memory situations. This fix adds support to create queue pair with GFP_NOIO flag for connected mode only to cleanly fail the create queue pair in those situations. This was previously fixed in qib but needed to get ported to hfi1. This patch handles that for both hardwares in the new rdmavt common layer. Reviewed-by:

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. Reviewed-by:

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:

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

Add pkey table in rdi per port data structure. Also bring in related pkey functions. Drivers will still be responsible for allocating and maintaining the pkey table. However they need to tell rdmavt where to find the pkey table. We can not move the pkey table up into rdmavt because drivers need to manipulate this long before registering with it. Reviewed-by:
