From 6f3603367b8f7c34598fdfc1058622e0e1951e98 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Thu, 12 Apr 2012 07:51:08 -0700 Subject: [PATCH] IB/srpt: Set srq_type to IB_SRQT_BASIC Since commit 96104eda0169 ("RDMA/core: Add SRQ type field"), kernel users of SRQs need to specify srq_type = IB_SRQT_BASIC in struct ib_srq_init_attr, or else most low-level drivers will fail in when srpt_add_one() calls ib_create_srq() and gets -ENOSYS. (mlx4_ib works OK nearly all of the time, because it just needs srq_type != IB_SRQT_XRC. And apparently nearly everyone using ib_srpt is using mlx4 hardware) Reported-by: Alexey Shvetsov Cc: Signed-off-by: Roland Dreier --- drivers/infiniband/ulp/srpt/ib_srpt.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/infiniband/ulp/srpt/ib_srpt.c b/drivers/infiniband/ulp/srpt/ib_srpt.c index 69e2ad06e515..daf21b899999 100644 --- a/drivers/infiniband/ulp/srpt/ib_srpt.c +++ b/drivers/infiniband/ulp/srpt/ib_srpt.c @@ -3232,6 +3232,7 @@ static void srpt_add_one(struct ib_device *device) srq_attr.attr.max_wr = sdev->srq_size; srq_attr.attr.max_sge = 1; srq_attr.attr.srq_limit = 0; + srq_attr.srq_type = IB_SRQT_BASIC; sdev->srq = ib_create_srq(sdev->pd, &srq_attr); if (IS_ERR(sdev->srq)) -- 2.20.1
