The series aims to add support for Low latency push path in some of the bnxt devices. The low latency implementation is supported only for the user applications. Also, the code is modified to use common mmap helper functions exported by IB core. User library changes are in the pull request https://github.com/linux-rdma/rdma-core/pull/1321 Please review and apply Thanks, Selvin Xavier v4 -> v5: - Added patch 3 to optimize bnxt_re_init_hwrm_hdr parameters - Avoid memset from the callers of bnxt_re_init_hwrm_hdr - Rebased the patches to the latest from leon-for-next v3-> v4: - Remove the newly added comp_mask in the alloc_pd resp. This is not required after using the new UAPI mechanism. - Return -EINVAL if WC page mmap requested for an unsupported adapter. v2-> v3: - Rebasing after the merge window - Fix the return value check in bnxt_re_hwrm_qcfg v1 - v2: - Fixes the review comments from Leon and Jason - As suggested by Jason, implements the new uapi driver definitions for allocating pages in the driver and return the cookie for mmap Selvin Xavier (7): RDMA/bnxt_re: Use the common mmap helper functions RDMA/bnxt_re: Add disassociate ucontext support RDMA/bnxt_re: Optimize the bnxt_re_init_hwrm_hdr usage RDMA/bnxt_re: Query function capabilities from firmware RDMA/bnxt_re: Move the interface version to chip context structure RDMA/bnxt_re: Reorg the bar mapping RDMA/bnxt_re: Enable low latency push drivers/infiniband/hw/bnxt_re/bnxt_re.h | 3 + drivers/infiniband/hw/bnxt_re/ib_verbs.c | 263 ++++++++++++++++++++++++++--- drivers/infiniband/hw/bnxt_re/ib_verbs.h | 19 +++ drivers/infiniband/hw/bnxt_re/main.c | 162 ++++++++++++++---- drivers/infiniband/hw/bnxt_re/qplib_fp.c | 4 +- drivers/infiniband/hw/bnxt_re/qplib_rcfw.h | 2 + drivers/infiniband/hw/bnxt_re/qplib_res.c | 177 ++++++++++++------- drivers/infiniband/hw/bnxt_re/qplib_res.h | 33 +++- drivers/infiniband/hw/bnxt_re/qplib_sp.c | 3 + drivers/infiniband/hw/bnxt_re/qplib_sp.h | 1 + include/uapi/rdma/bnxt_re-abi.h | 28 +++ 11 files changed, 565 insertions(+), 130 deletions(-) -- 2.5.5
