This series introduces the RoCE driver for the Broadcom NetXtreme-E 10/25/40/50G RoCE HCAs. This driver is dependent on the bnxt_en NIC driver and is based on the bnxt_re branch in linux-rdma repository. bnxt_en changes required for this patch series are already available afore mentioned branch.
These changes are available for your reference in the bnxt_re_v3 branch of following repository. https://github.com/Broadcom/linux-rdma-nxt/ Doug, Please review and consider applying this to linux-rdma repository for 4.11 merge cycle. Thanks, Selvin Xavier v2->v3: * Fix 0day build breakage * Fix cocci, kbuild robot, sparse, smatch and checkpatch warnings * Changed the filename bnxt_re_uverbs_abi.h to bnxtre-abi.h * Removed the __packed qualifier from the uverbs structure and adjusted the structure alignment to 64bits. * Added retry count to bail out in case of delayed or no response to FW commands * Removed the debugfs support from this patch series * Changed some of the defines as inline functions based on Jason's comment * Split two functions to get rid of switch within switch construct * Removed bnxt_re_copy_to_udata as it is just a wrapper for ib_copy_to_udata * Added maintainers information to MAINTAINERS file v1-> v2: * The license text in each file updated to reflect Dual license. * Makefile and Kconfig changes are pushed to the last patch * Moved bnxt_re_uverbs_abi.h to include/uapi/rdma folder * Remove duplicate structure definitions from bnxt_re_hsi.h as it is available in the corresponding bnxt_en header file (bnxt_hsi.h) * Removed some unused code reported during code review. * Fixed few sparse warnings Selvin Xavier (21): bnxt_re: Add bnxt_re RoCE driver files bnxt_re: Introducing autogenerated Host Software Interface(hsi) file bnxt_re: register with the NIC driver bnxt_re: Enabling RoCE control path bnxt_re: Adding Notification Queue support bnxt_re: Support for PD, ucontext and mmap verbs bnxt_re: Support for query and modify device verbs bnxt_re: Adding support for port related verbs bnxt_re: Support for GID related verbs bnxt_re: Support for CQ verbs bnxt_re: Support for AH verbs bnxt_re: Support memory registration verbs bnxt_re: Support QP verbs bnxt_re: Support post_send verb bnxt_re: Support post_recv bnxt_re: Support poll_cq verb bnxt_re: Handling dispatching of events to IB stack bnxt_re: Support for DCB bnxt_re: Set uverbs command mask bnxt_re: Add QP event handling bnxt_re: Add bnxt_re driver build support MAINTAINERS | 11 + drivers/infiniband/Kconfig | 2 + drivers/infiniband/hw/Makefile | 1 + drivers/infiniband/hw/bnxtre/Kconfig | 9 + drivers/infiniband/hw/bnxtre/Makefile | 6 + drivers/infiniband/hw/bnxtre/bnxt_qplib_fp.c | 2167 +++++++++++++++ drivers/infiniband/hw/bnxtre/bnxt_qplib_fp.h | 441 ++++ drivers/infiniband/hw/bnxtre/bnxt_qplib_rcfw.c | 692 +++++ drivers/infiniband/hw/bnxtre/bnxt_qplib_rcfw.h | 231 ++ drivers/infiniband/hw/bnxtre/bnxt_qplib_res.c | 825 ++++++ drivers/infiniband/hw/bnxtre/bnxt_qplib_res.h | 223 ++ drivers/infiniband/hw/bnxtre/bnxt_qplib_sp.c | 838 ++++++ drivers/infiniband/hw/bnxtre/bnxt_qplib_sp.h | 160 ++ drivers/infiniband/hw/bnxtre/bnxt_re.h | 150 ++ drivers/infiniband/hw/bnxtre/bnxt_re_hsi.h | 2821 ++++++++++++++++++++ drivers/infiniband/hw/bnxtre/bnxt_re_ib_verbs.c | 3206 +++++++++++++++++++++++ drivers/infiniband/hw/bnxtre/bnxt_re_ib_verbs.h | 196 ++ drivers/infiniband/hw/bnxtre/bnxt_re_main.c | 1340 ++++++++++ include/uapi/rdma/bnxtre-abi.h | 89 + 19 files changed, 13408 insertions(+) create mode 100644 drivers/infiniband/hw/bnxtre/Kconfig create mode 100644 drivers/infiniband/hw/bnxtre/Makefile create mode 100644 drivers/infiniband/hw/bnxtre/bnxt_qplib_fp.c create mode 100644 drivers/infiniband/hw/bnxtre/bnxt_qplib_fp.h create mode 100644 drivers/infiniband/hw/bnxtre/bnxt_qplib_rcfw.c create mode 100644 drivers/infiniband/hw/bnxtre/bnxt_qplib_rcfw.h create mode 100644 drivers/infiniband/hw/bnxtre/bnxt_qplib_res.c create mode 100644 drivers/infiniband/hw/bnxtre/bnxt_qplib_res.h create mode 100644 drivers/infiniband/hw/bnxtre/bnxt_qplib_sp.c create mode 100644 drivers/infiniband/hw/bnxtre/bnxt_qplib_sp.h create mode 100644 drivers/infiniband/hw/bnxtre/bnxt_re.h create mode 100644 drivers/infiniband/hw/bnxtre/bnxt_re_hsi.h create mode 100644 drivers/infiniband/hw/bnxtre/bnxt_re_ib_verbs.c create mode 100644 drivers/infiniband/hw/bnxtre/bnxt_re_ib_verbs.h create mode 100644 drivers/infiniband/hw/bnxtre/bnxt_re_main.c create mode 100644 include/uapi/rdma/bnxtre-abi.h -- 2.5.5
