From 4bb02e9572af1383038d83ad196d7166c515f2ee Mon Sep 17 00:00:00 2001 From: Mike Marciniszyn Date: Fri, 14 Jun 2019 12:32:44 -0400 Subject: IB/hfi1: Use aborts to trigger RC throttling SDMA and pio flushes will cause a lot of packets to be transmitted after a link has gone down, using a lot of CPU to retransmit packets. Fix for RC QPs by recognizing the flush status and: - Forcing a timer start - Putting the QP into a "send one" mode Fixes: 7724105686e7 ("IB/hfi1: add driver files") Reviewed-by: Kaike Wan Signed-off-by: Mike Marciniszyn Signed-off-by: Dennis Dalessandro Signed-off-by: Doug Ledford --- drivers/infiniband/hw/hfi1/verbs.h | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/infiniband/hw/hfi1/verbs.h') diff --git a/drivers/infiniband/hw/hfi1/verbs.h b/drivers/infiniband/hw/hfi1/verbs.h index 7ecb8ed4a1d9..ae9582ddbc8f 100644 --- a/drivers/infiniband/hw/hfi1/verbs.h +++ b/drivers/infiniband/hw/hfi1/verbs.h @@ -416,6 +416,7 @@ void hfi1_rc_hdrerr( u8 ah_to_sc(struct ib_device *ibdev, struct rdma_ah_attr *ah_attr); +void hfi1_rc_verbs_aborted(struct rvt_qp *qp, struct hfi1_opa_header *opah); void hfi1_rc_send_complete(struct rvt_qp *qp, struct hfi1_opa_header *opah); void hfi1_ud_rcv(struct hfi1_packet *packet); -- cgit v1.2.3
