From eb00b9a08b9dbb0aad7c59d113f35206c7ac2eac Mon Sep 17 00:00:00 2001 From: Wenpeng Liang Date: Mon, 22 Aug 2022 18:44:50 +0800 Subject: RDMA/hns: Add or remove CQ's restrack attributes Remove the resttrack attributes from the queue context held by ROCEE, and add the resttrack attributes from the queue information maintained by the driver. For example: $ rdma res show cq dev hns_0 cqn 14 -dd -jp [ { "ifindex": 4, "ifname": "hns_0", "cqn": 14, "cqe": 127, "users": 1, "adaptive-moderation": false, "ctxn": 8, "pid": 1524, "comm": "ib_send_bw" }, "drv_cq_depth": 128, "drv_cons_index": 0, "drv_cqe_size": 32, "drv_arm_sn": 1 } Link: https://lore.kernel.org/r/20220822104455.2311053-3-liangwenpeng@huawei.com Signed-off-by: Wenpeng Liang Signed-off-by: Leon Romanovsky --- drivers/infiniband/hw/hns/hns_roce_restrack.c | 67 ++++----------------------- 1 file changed, 10 insertions(+), 57 deletions(-) (limited to 'drivers/infiniband') diff --git a/drivers/infiniband/hw/hns/hns_roce_restrack.c b/drivers/infiniband/hw/hns/hns_roce_restrack.c index 83417be15d3f..2e8299784bc2 100644 --- a/drivers/infiniband/hw/hns/hns_roce_restrack.c +++ b/drivers/infiniband/hw/hns/hns_roce_restrack.c @@ -9,72 +9,25 @@ #include "hns_roce_device.h" #include "hns_roce_hw_v2.h" -static int hns_roce_fill_cq(struct sk_buff *msg, - struct hns_roce_v2_cq_context *context) -{ - if (rdma_nl_put_driver_u32(msg, "state", - hr_reg_read(context, CQC_ARM_ST))) - - goto err; - - if (rdma_nl_put_driver_u32(msg, "ceqn", - hr_reg_read(context, CQC_CEQN))) - goto err; - - if (rdma_nl_put_driver_u32(msg, "cqn", - hr_reg_read(context, CQC_CQN))) - goto err; - - if (rdma_nl_put_driver_u32(msg, "hopnum", - hr_reg_read(context, CQC_CQE_HOP_NUM))) - goto err; - - if (rdma_nl_put_driver_u32(msg, "pi", - hr_reg_read(context, CQC_CQ_PRODUCER_IDX))) - goto err; - - if (rdma_nl_put_driver_u32(msg, "ci", - hr_reg_read(context, CQC_CQ_CONSUMER_IDX))) - goto err; - - if (rdma_nl_put_driver_u32(msg, "coalesce", - hr_reg_read(context, CQC_CQ_MAX_CNT))) - goto err; - - if (rdma_nl_put_driver_u32(msg, "period", - hr_reg_read(context, CQC_CQ_PERIOD))) - goto err; - - if (rdma_nl_put_driver_u32(msg, "cnt", - hr_reg_read(context, CQC_CQE_CNT))) - goto err; - - return 0; - -err: - return -EMSGSIZE; -} - int hns_roce_fill_res_cq_entry(struct sk_buff *msg, struct ib_cq *ib_cq) { - struct hns_roce_dev *hr_dev = to_hr_dev(ib_cq->device); struct hns_roce_cq *hr_cq = to_hr_cq(ib_cq); - struct hns_roce_v2_cq_context context; struct nlattr *table_attr; - int ret; - - if (!hr_dev->hw->query_cqc) - return -EINVAL; - - ret = hr_dev->hw->query_cqc(hr_dev, hr_cq->cqn, &context); - if (ret) - return -EINVAL; table_attr = nla_nest_start(msg, RDMA_NLDEV_ATTR_DRIVER); if (!table_attr) return -EMSGSIZE; - if (hns_roce_fill_cq(msg, &context)) + if (rdma_nl_put_driver_u32(msg, "cq_depth", hr_cq->cq_depth)) + goto err; + + if (rdma_nl_put_driver_u32(msg, "cons_index", hr_cq->cons_index)) + goto err; + + if (rdma_nl_put_driver_u32(msg, "cqe_size", hr_cq->cqe_size)) + goto err; + + if (rdma_nl_put_driver_u32(msg, "arm_sn", hr_cq->arm_sn)) goto err; nla_nest_end(msg, table_attr); -- cgit
