From: Leon Romanovsky <leonro@xxxxxxxxxxxx> Hi, This series from Mark provides dynamic statistics infrastructure. He uses netlink interface to configure and retrieve those counters. This infrastructure allows to users monitor various objects by binding to them counters. As the beginning, we used QP object as target for those counters, but future patches will include ODP MR information too. Two binding modes are supported: - Auto: This allows a user to build automatic set of objects to a counter according to common criteria. For example in a per-type scheme, where in one process all QPs with same QP type are bound automatically to a single counter. - Manual: This allows a user to manually bind objects on a counter. Those two modes are mutual-exclusive with separation between processes, objects created by different processes cannot be bound to a same counter. For objects which don't support counter binding, we will return pre-allocated counters. $ rdma statistic qp set link mlx5_2/1 auto type on $ rdma statistic qp set link mlx5_2/1 auto off $ rdma statistic qp bind link mlx5_2/1 lqpn 178 $ rdma statistic qp unbind link mlx5_2/1 cntn 4 lqpn 178 $ rdma statistic show $ rdma statistic qp mode Thanks Mark Zhang (16): net/mlx5: Add rts2rts_qp_counters_set_id field in hca cap RDMA/restrack: Introduce statistic counter RDMA/restrack: Add an API to attach a task to a resource RDMA/restrack: Make is_visible_in_pid_ns() as an API RDMA/counter: Add set/clear per-port auto mode support RDMA/counter: Add "auto" configuration mode support IB/mlx5: Support set qp counter IB/mlx5: Add counter set id as a parameter for mlx5_ib_query_q_counters() IB/mlx5: Support statistic q counter configuration RDMA/nldev: Allow counter auto mode configuration through RDMA netlink RDMA/netlink: Implement counter dumpit callback IB/mlx5: Add counter_alloc_stats() and counter_update_stats() support RDMA/core: Get sum value of all counters when perform a sysfs stat read RDMA/counter: Allow manual mode configuration support RDMA/nldev: Allow counter manual mode configuration through RDMA netlink RDMA/nldev: Allow get counter mode through RDMA netlink drivers/infiniband/core/Makefile | 2 +- drivers/infiniband/core/counters.c | 652 +++++++++++++++++++++++++++ drivers/infiniband/core/device.c | 14 + drivers/infiniband/core/nldev.c | 427 +++++++++++++++++- drivers/infiniband/core/restrack.c | 49 +- drivers/infiniband/core/restrack.h | 3 + drivers/infiniband/core/sysfs.c | 10 +- drivers/infiniband/core/verbs.c | 9 + drivers/infiniband/hw/mlx5/main.c | 88 +++- drivers/infiniband/hw/mlx5/mlx5_ib.h | 6 + drivers/infiniband/hw/mlx5/qp.c | 76 +++- include/linux/mlx5/mlx5_ifc.h | 4 +- include/linux/mlx5/qp.h | 1 + include/rdma/ib_verbs.h | 32 ++ include/rdma/rdma_counter.h | 64 +++ include/rdma/restrack.h | 4 + include/uapi/rdma/rdma_netlink.h | 52 ++- 17 files changed, 1462 insertions(+), 31 deletions(-) create mode 100644 drivers/infiniband/core/counters.c create mode 100644 include/rdma/rdma_counter.h -- 2.20.1
