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 getting submitted in the pull request https://github.com/linux-rdma/rdma-core/pull/1321 Please review. Thanks, Selvin Xavier 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 (6): RDMA/bnxt_re: Use the common mmap helper functions RDMA/bnxt_re: Add disassociate ucontext support 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 | 265 ++++++++++++++++++++++++++--- drivers/infiniband/hw/bnxt_re/ib_verbs.h | 19 +++ drivers/infiniband/hw/bnxt_re/main.c | 117 ++++++++++++- drivers/infiniband/hw/bnxt_re/qplib_fp.c | 14 +- drivers/infiniband/hw/bnxt_re/qplib_rcfw.c | 2 +- drivers/infiniband/hw/bnxt_re/qplib_rcfw.h | 1 + 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 | 32 ++++ 12 files changed, 558 insertions(+), 109 deletions(-) -- 2.5.5
