From cc26aee100588a3f293921342a307b6309ace193 Mon Sep 17 00:00:00 2001 From: Wenpeng Liang Date: Mon, 27 Sep 2021 20:55:56 +0800 Subject: RDMA/hns: Fix the size setting error when copying CQE in clean_cq() The size of CQE is different for different versions of hardware, so the driver needs to specify the size of CQE explicitly. Fixes: 09a5f210f67e ("RDMA/hns: Add support for CQE in size of 64 Bytes") Link: https://lore.kernel.org/r/20210927125557.15031-2-liangwenpeng@huawei.com Signed-off-by: Wenpeng Liang Signed-off-by: Jason Gunthorpe --- drivers/infiniband/hw/hns/hns_roce_hw_v2.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/infiniband/hw/hns') diff --git a/drivers/infiniband/hw/hns/hns_roce_hw_v2.c b/drivers/infiniband/hw/hns/hns_roce_hw_v2.c index a9c00a2e8ebd..d5f3faa1627a 100644 --- a/drivers/infiniband/hw/hns/hns_roce_hw_v2.c +++ b/drivers/infiniband/hw/hns/hns_roce_hw_v2.c @@ -3299,7 +3299,7 @@ static void __hns_roce_v2_cq_clean(struct hns_roce_cq *hr_cq, u32 qpn, dest = get_cqe_v2(hr_cq, (prod_index + nfreed) & hr_cq->ib_cq.cqe); owner_bit = hr_reg_read(dest, CQE_OWNER); - memcpy(dest, cqe, sizeof(*cqe)); + memcpy(dest, cqe, hr_cq->cqe_size); hr_reg_write(dest, CQE_OWNER, owner_bit); } } -- cgit v1.2.3
