Sending V1 to address few notes from Jason, details below. This series from Ariel implements the libibverbs 'Completion timestamping' API in the mlx4 provider. It implements the new iterator style CQ polling API with support of querying specific CQ fields, among them the completion timestamp. Benchmarks we ran in our test lab found that this new approach generally equals to the legacy API but *not* worse than. As the new API enables extending the polled fields we can overall say that it's a better API than the legacy one. Pull request was sent: https://github.com/linux-rdma/rdma-core/pull/61 Yishai Changes from V0: - Add an extra two pre patches so that likely/unlikely and ALWAYS_INLINE will be defined in one place and make the relevant cleanup. - Drop redundant 'inline' from mlx4_cq_read_xxx functions as they are called directly outside of mlx4 by their function pointer. Ariel Levkovich (10): Handle likely/unlikely in a single place Handle always_inline attribute in util/compiler.h mlx4: sl_vid field in struct mlx4_cqe should be 16 bit mlx4: Refactor mlx4_poll_one mlx4: Add lazy CQ polling mlx4: Add inline functions to read completion's attributes mlx4: Add ability to poll CQs through iterator's style API mlx4: Add support for creating an extended CQ mlx4: Add ibv_query_device_ex support mlx4: Add ibv_query_rt_values providers/cxgb4/t4.h | 2 +- providers/hns/hns_roce_u.h | 5 +- providers/i40iw/i40iw_umain.h | 8 +- providers/mlx4/cq.c | 490 ++++++++++++++++++++++++++++++++++-------- providers/mlx4/mlx4-abi.h | 27 +++ providers/mlx4/mlx4.c | 41 +++- providers/mlx4/mlx4.h | 49 +++-- providers/mlx4/verbs.c | 238 ++++++++++++++++++-- providers/mlx5/mlx5.h | 12 +- providers/nes/nes_umain.h | 8 +- util/compiler.h | 22 ++ 11 files changed, 746 insertions(+), 156 deletions(-) -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
