Remove qib query pkey function which is no longer needed as this is now being done in rdmavt. The allocation and maintenance of the list still resides in the driver. 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:

With this commit, the drivers using rdmavt need not define query_device function. But they should fill in the IB device attributes structure rvt_dev_info.dparms.props Reviewed-by:

qib needs to reserve only one qpn for non-verbs stuff. Also fixed the for loop to reserve the end qpn. Reviewed-by:

Until all queue pair functionality is moved to rdmavt we need to provide access to the reset function. This is only temporary and will be reverted back to a static, non exported function in the end. 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 removes most of the uses of QIB_PERMISSIBVE_LID and QIB_MULTICAST_LID_BASE in favor of the recently added IB_* versions. There are still minor uses in AH functions as well as the QIB_* defines but those will be removed in a follow on patch. 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:

Add table init as well as teardown for handling qpn maps. Drivers can still provide this functionality by setting the QP_INIT_DRIVER bit. Reviewed-by:

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. Reviewed-by:

Converge the ibport data structures of qib and hfi1 into a common ib port structure. Also provides a place to keep track of these ports in case rdmavt needs it. Along with this goes an attach and detach function for drivers to use to notify rdmavt of the ports. Reviewed-by:
