2016-12-11IB/hfi1: Remove critical section gap in sc_buffer_alloc()Sebastian Sanchez1-2/+0
In sc_buffer_alloc(), the sc->alloc_lock is released before calling sc_release_update(), and it is reacquired after the function call. This causes CPU lock trading. Fix it by not dropping the lock before calling sc_release_update().

2016-12-11IB/hfi1: Remove usage of qp->s_cur_sgeMitko Haralanov4-15/+13
The s_cur_sge field in the qp structure holds a pointer to the SGE of the currently processed WQE. It assumes the protection of the RVT_S_BUSY flag to prevent the changing of this field while the send engine is using it. This scheme works as long as there is only one instance of the send engine running at a time. Scaling of the send engine to multiple cores would break this assumption as there could be multiple instances of the send engine running on different CPUs. This opens a window where the QP's RVT_S_BUSY flag is not set but the send engine is still running. To prevent accidental changing of the s_cur_sge pointer, the QP's dependence on it is removed. The SGE pointer is now stored in the verbs_txreq, which is a per-packet data structure. This ensures that each individual packet has it's own pointer, which is setup while the RVT_S_BUSY flag is set.
