The QSFP memory cache reads both lower and upper page 0H in one shot, which leads to the address counter wrapping around to the beginning of lower page 00H at byte 128, as defined by SFF-8636. This patch fixes this by modifying the underlying QSFP read and writes to avoid this wrap around. Reviewed-by:

Removing QSFP cable should report 'No Local Media' instead of 'Transient' as reported by 'opaportinfo'. Workaround is to change the state to OPA_LINKDOWN_REASON_LOCAL_MEDIA_NOT_INSTALLED in cable handler. With cable still removed, 'opaportinfo bounce' should not cause a state change to Polling, as reported by 'opaportinfo'. Resolution is to prevent physical state change from Offline->Polling. Use a macro to mask lower nibble of OPA_LINKDOWN_REASON* as needed for offline_disabled_reason. Reviewed-by:

This patch removes the post_send and post_one_send from the hfi1 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:

The completion queue is not a complex data structure and it can be removed at the same time as its functions. Unlike the more complicated queue pair which was done in multiple patches. This single patch removes all traces of hfi1 specific completeion queues from the hfi1 driver. Reviewed-by:

This patch does the actual removal of the queue pair from the hfi1 driver along with a number of dependent data structures. These were moved to rvt. It also removes the MR functions to use those in rdmavt. These two pieces can not reasonably be split apart becuase they depend on each other. 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:

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:
