From: Long Li <lon...@microsoft.com> MANA is a network interface card to be used in the Azure cloud environment. MANA provides safe access to user memory through memory registration. It has IOMMU built into the hardware.
MANA uses IB verbs and RDMA layer to configure hardware resources. It requires the corresponding RDMA kernel-mode and user-mode drivers. The MANA RDMA kernel-mode driver is being reviewed at: https://patchwork.kernel.org/project/netdevbpf/list/?series=678843&state=* The MANA RDMA user-mode driver is being reviewed at: https://github.com/linux-rdma/rdma-core/pull/1177 Long Li (18): net/mana: add basic driver with build environment and doc net/mana: device configuration and stop net/mana: report supported ptypes net/mana: support link update net/mana: support device removal interrupts net/mana: report device info net/mana: configure RSS net/mana: configure Rx queues net/mana: configure Tx queues net/mana: implement memory registration net/mana: implement the hardware layer operations net/mana: start/stop Tx queues net/mana: start/stop Rx queues net/mana: receive packets net/mana: send packets net/mana: start/stop device net/mana: report queue stats net/mana: support Rx interrupts MAINTAINERS | 6 + doc/guides/nics/features/mana.ini | 19 + doc/guides/nics/index.rst | 1 + doc/guides/nics/mana.rst | 73 ++ drivers/net/mana/gdma.c | 303 ++++++ drivers/net/mana/mana.c | 1502 +++++++++++++++++++++++++++++ drivers/net/mana/mana.h | 542 +++++++++++ drivers/net/mana/meson.build | 48 + drivers/net/mana/mp.c | 336 +++++++ drivers/net/mana/mr.c | 348 +++++++ drivers/net/mana/rx.c | 531 ++++++++++ drivers/net/mana/tx.c | 416 ++++++++ drivers/net/mana/version.map | 3 + drivers/net/meson.build | 1 + 14 files changed, 4129 insertions(+) create mode 100644 doc/guides/nics/features/mana.ini create mode 100644 doc/guides/nics/mana.rst create mode 100644 drivers/net/mana/gdma.c create mode 100644 drivers/net/mana/mana.c create mode 100644 drivers/net/mana/mana.h create mode 100644 drivers/net/mana/meson.build create mode 100644 drivers/net/mana/mp.c create mode 100644 drivers/net/mana/mr.c create mode 100644 drivers/net/mana/rx.c create mode 100644 drivers/net/mana/tx.c create mode 100644 drivers/net/mana/version.map -- 2.17.1
