In MANA, the RDMA device is modeled as an auxiliary device to the Ethernet device. The first 11 patches modify the MANA Ethernet driver to support RDMA driver. The last patch implementes the RDMA driver. The user-mode of the driver is being reviewed at: https://github.com/linux-rdma/rdma-core/pull/1177 Ajay Sharma (3): net: mana: Set the DMA device max segment size net: mana: Define and process GDMA response code GDMA_STATUS_MORE_ENTRIES net: mana: Define data structures for protection domain and memory registration Long Li (9): net: mana: Add support for auxiliary device net: mana: Record the physical address for doorbell page region net: mana: Handle vport sharing between devices net: mana: Add functions for allocating doorbell page from GDMA net: mana: Export Work Queue functions for use by RDMA driver net: mana: Record port number in netdev net: mana: Move header files to a common location net: mana: Define max values for SGL entries RDMA/mana_ib: Add a driver for Microsoft Azure Network Adapter MAINTAINERS | 4 + drivers/infiniband/Kconfig | 1 + drivers/infiniband/hw/Makefile | 1 + drivers/infiniband/hw/mana/Kconfig | 7 + drivers/infiniband/hw/mana/Makefile | 4 + drivers/infiniband/hw/mana/cq.c | 80 +++ drivers/infiniband/hw/mana/device.c | 129 ++++ drivers/infiniband/hw/mana/main.c | 555 ++++++++++++++++++ drivers/infiniband/hw/mana/mana_ib.h | 165 ++++++ drivers/infiniband/hw/mana/mr.c | 133 +++++ drivers/infiniband/hw/mana/qp.c | 501 ++++++++++++++++ drivers/infiniband/hw/mana/wq.c | 114 ++++ .../net/ethernet/microsoft/mana/gdma_main.c | 96 ++- .../net/ethernet/microsoft/mana/hw_channel.c | 6 +- .../net/ethernet/microsoft/mana/mana_bpf.c | 2 +- drivers/net/ethernet/microsoft/mana/mana_en.c | 177 +++++- .../ethernet/microsoft/mana/mana_ethtool.c | 2 +- .../net/ethernet/microsoft/mana/shm_channel.c | 2 +- .../microsoft => include/net}/mana/gdma.h | 162 ++++- .../net}/mana/hw_channel.h | 0 .../microsoft => include/net}/mana/mana.h | 23 +- include/net/mana/mana_auxiliary.h | 10 + .../net}/mana/shm_channel.h | 0 include/uapi/rdma/ib_user_ioctl_verbs.h | 1 + include/uapi/rdma/mana-abi.h | 66 +++ 25 files changed, 2196 insertions(+), 45 deletions(-) create mode 100644 drivers/infiniband/hw/mana/Kconfig create mode 100644 drivers/infiniband/hw/mana/Makefile create mode 100644 drivers/infiniband/hw/mana/cq.c create mode 100644 drivers/infiniband/hw/mana/device.c create mode 100644 drivers/infiniband/hw/mana/main.c create mode 100644 drivers/infiniband/hw/mana/mana_ib.h create mode 100644 drivers/infiniband/hw/mana/mr.c create mode 100644 drivers/infiniband/hw/mana/qp.c create mode 100644 drivers/infiniband/hw/mana/wq.c rename {drivers/net/ethernet/microsoft => include/net}/mana/gdma.h (79%) rename {drivers/net/ethernet/microsoft => include/net}/mana/hw_channel.h (100%) rename {drivers/net/ethernet/microsoft => include/net}/mana/mana.h (94%) create mode 100644 include/net/mana/mana_auxiliary.h rename {drivers/net/ethernet/microsoft => include/net}/mana/shm_channel.h (100%) create mode 100644 include/uapi/rdma/mana-abi.h
