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 for-4.11 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_v5 branch of following repository. https://github.com/Broadcom/linux-rdma-nxt/ Doug, This patchset addresses review comments from you and Leon. This series also includes some changes required for the latest FW. Please consider applying this to linux-rdma tree. Thanks, Selvin Xavier v4->v5: * Removes rdev ref_count as this is not necessary. * Adds a check to see if the device is supporting RoCE * Updating the PF FW communication channel offset as per the latest FW changes * Use min_t macro to calculate the number CQ and QP entries * Adds ib_udata parameter to create_ah verb * Uses ETH_P_IBOE macro for RoCE ethertype * Code refactoring based on the review comments from Leon v3->v4: * Changes driver folder name to bnxt_re and remove the bnxt_re/bnxt prefix from the individual files inside the driver folder. * Changes the file name bnxtre-abi to bnxt_re-abi.h to align with convention <module_name>-abi.h * Updates the Makefile and Kconfig file with new format change. 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): RDMA/bnxt_re: Add bnxt_re RoCE driver files RDMA/bnxt_re: Introducing autogenerated Host Software Interface(hsi) file RDMA/bnxt_re: register with the NIC driver RDMA/bnxt_re: Enabling RoCE control path RDMA/bnxt_re: Adding Notification Queue support RDMA/bnxt_re: Support for PD, ucontext and mmap verbs RDMA/bnxt_re: Support for query and modify device verbs RDMA/bnxt_re: Adding support for port related verbs RDMA/bnxt_re: Support for GID related verbs RDMA/bnxt_re: Support for CQ verbs RDMA/bnxt_re: Support for AH verbs RDMA/bnxt_re: Support memory registration verbs RDMA/bnxt_re: Support QP verbs RDMA/bnxt_re: Support post_send verb RDMA/bnxt_re: Support post_recv RDMA/bnxt_re: Support poll_cq verb RDMA/bnxt_re: Handling dispatching of events to IB stack RDMA/bnxt_re: Support for DCB RDMA/bnxt_re: Set uverbs command mask RDMA/bnxt_re: Add QP event handling RDMA/bnxt_re: Add bnxt_re driver build support MAINTAINERS | 11 + drivers/infiniband/Kconfig | 2 + drivers/infiniband/hw/Makefile | 1 + drivers/infiniband/hw/bnxt_re/Kconfig | 9 + drivers/infiniband/hw/bnxt_re/Makefile | 6 + drivers/infiniband/hw/bnxt_re/bnxt_re.h | 146 ++ drivers/infiniband/hw/bnxt_re/ib_verbs.c | 3202 ++++++++++++++++++++++++++++ drivers/infiniband/hw/bnxt_re/ib_verbs.h | 197 ++ drivers/infiniband/hw/bnxt_re/main.c | 1315 ++++++++++++ drivers/infiniband/hw/bnxt_re/qplib_fp.c | 2167 +++++++++++++++++++ drivers/infiniband/hw/bnxt_re/qplib_fp.h | 439 ++++ drivers/infiniband/hw/bnxt_re/qplib_rcfw.c | 694 ++++++ drivers/infiniband/hw/bnxt_re/qplib_rcfw.h | 231 ++ drivers/infiniband/hw/bnxt_re/qplib_res.c | 825 +++++++ drivers/infiniband/hw/bnxt_re/qplib_res.h | 223 ++ drivers/infiniband/hw/bnxt_re/qplib_sp.c | 838 ++++++++ drivers/infiniband/hw/bnxt_re/qplib_sp.h | 160 ++ drivers/infiniband/hw/bnxt_re/roce_hsi.h | 2821 ++++++++++++++++++++++++ include/uapi/rdma/bnxt_re-abi.h | 89 + 19 files changed, 13376 insertions(+) create mode 100644 drivers/infiniband/hw/bnxt_re/Kconfig create mode 100644 drivers/infiniband/hw/bnxt_re/Makefile create mode 100644 drivers/infiniband/hw/bnxt_re/bnxt_re.h create mode 100644 drivers/infiniband/hw/bnxt_re/ib_verbs.c create mode 100644 drivers/infiniband/hw/bnxt_re/ib_verbs.h create mode 100644 drivers/infiniband/hw/bnxt_re/main.c create mode 100644 drivers/infiniband/hw/bnxt_re/qplib_fp.c create mode 100644 drivers/infiniband/hw/bnxt_re/qplib_fp.h create mode 100644 drivers/infiniband/hw/bnxt_re/qplib_rcfw.c create mode 100644 drivers/infiniband/hw/bnxt_re/qplib_rcfw.h create mode 100644 drivers/infiniband/hw/bnxt_re/qplib_res.c create mode 100644 drivers/infiniband/hw/bnxt_re/qplib_res.h create mode 100644 drivers/infiniband/hw/bnxt_re/qplib_sp.c create mode 100644 drivers/infiniband/hw/bnxt_re/qplib_sp.h create mode 100644 drivers/infiniband/hw/bnxt_re/roce_hsi.h create mode 100644 include/uapi/rdma/bnxt_re-abi.h -- 2.5.5 -- 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
