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.

There is a a bug in defered ack stuff that causes a race with the destroy of a QP. A packet causes a defered ack to be pended by putting the QP into an rcd queue. A return from the driver interrupt processing will process that rcd queue of QPs and attempt to do a direct send of the ack. At this point no locks are held and the above QP could now be put in the reset state in the qp destroy logic. A refcount protects the QP while it is in the rcd queue so it isn't going anywhere yet. If the direct send fails to allocate a pio buffer, hfi1_schedule_send() is called to trigger sending an ack from the send engine. There is no state test in that code path. The refcount is then dropped from the driver.c caller potentially allowing the qp destroy to continue from its refcount wait in parallel with the workqueue scheduling of the qp.

Hanging has been observed while writing a file over NFSoRDMA. Dmesg on the server contains messages like these: [ 931.992501] svcrdma: Error -22 posting RDMA_READ [ 952.076879] svcrdma: Error -22 posting RDMA_READ [ 982.154127] svcrdma: Error -22 posting RDMA_READ [ 1012.235884] svcrdma: Error -22 posting RDMA_READ [ 1042.319194] svcrdma: Error -22 posting RDMA_READ Here is why: With the base memory management extension enabled, FRMR is used instead of FMR. The xprtrdma server issues each RDMA read request as the following bundle: (1)IB_WR_REG_MR, signaled; (2)IB_WR_RDMA_READ, signaled; (3)IB_WR_LOCAL_INV, signaled & fencing. These requests are signaled. In order to generate completion, the fast register work request is processed by the hfi1 send engine after being posted to the work queue, and the corresponding lkey is not valid until the request is processed. However, the rdmavt driver validates lkey when the RDMA read request is posted and thus it fails immediately with error -EINVAL (-22). This patch changes the work flow of local operations (fast register and local invalidate) so that fast register work requests are always processed immediately to ensure that the corresponding lkey is valid when subsequent work requests are posted. Local invalidate requests are processed immediately if fencing is not required and no previous local invalidate request is pending. To allow completion generation for signaled local operations that have been processed before posting to the work queue, an internal send flag RVT_SEND_COMPLETION_ONLY is added. The hfi1 send engine checks this flag and only generates completion for such requests.

All of that code was very similar, which meant that it could be pulled into a single function used by the different QP types.

The change requires a new pio_busy field in the iowait structure to track the number of outstanding pios. The new counter together with the sdma counter serve as the basis for a packet by packet decision as to which egress mechanism to use. Since packets given to different egress mechanisms are not ordered, this scheme will preserve the order. The iowait drain/wait mechanisms are extended for a pio case. An additional qp wait flag is added for the PIO drain wait case. Currently the only pio wait is for buffers, so the no_bufs_available() routine name is changed to pio_wait() and a third argument is passed with one of the two pio wait flags to generalize the routine. A module parameter is added to hold a configurable threshold. For now, the module parameter is zero. A heuristic routine is added to return the func pointer of the proper egress routine to use. The heuristic is as follows: - SMI always uses pio - GSI,UD qps <= threshold use pio - UD qps > threadhold use sdma o No coordination with sdma is required because order is not required and this qp pio count is not maintained for UD - RC/UC ONLY packets <= threshold chose as follows: o If sdmas pending, use SDMA o Otherwise use pio and enable the pio tracking count at the time the pio buffer is allocated - RC/UC ONLY packets > threshold use SDMA o If pio's are pending the pio_wait with the new wait flag is called to delay for pios to drain The threshold is potentially reduced by the QP's mtu. The sc_buffer_alloc() has two additional args (a callback, a void *) which are exploited by the RC/UC cases to pass a new complete routine and a qp *. When the shadow ring completes the credit associated with a packet, the new complete routine is called. The verbs_pio_complete() will then decrement the busy count and trigger any drain waiters in qp destroy or reset.
