2016-03-10IB/rdmavt: Add modify qpDennis Dalessandro2-9/+525
Add modify qp and supporting functions. Reviewed-by: Mike Marciniszyn <[email protected]> Reviewed-by: Ira Weiny <[email protected]> Signed-off-by: Dennis Dalessandro <[email protected]> Signed-off-by: Doug Ledford <[email protected]>
2016-03-10IB/rdmavt: Add support for tracing eventsDennis Dalessandro4-2/+143
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.

2016-03-10IB/rdmavt: Add post send to rdmavtDennis Dalessandro1-12/+171
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.

2016-03-10IB/rdmavt: Support creating qps with GFP_NOIO flagMike Marciniszyn1-13/+43
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.

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.

2016-03-10IB/rdmavt: Break rdma_vt main include header file upDennis Dalessandro1-2/+2
Until all functionality is moved over to rdmavt drivers still need to access a number of fields in data structures that are predominantly meant to be used by rdmavt. Once these rdmavt_<ibta_object>.h header files are no longer being touched by drivers their content should be moved to rdmavt/<ibta_object>.h. While here move a couple #defines over to more general IB verbs header files because they fit better.
