This is a revised version of the Hyper-V native bus (VMbus) and network device (netvsc) drivers. This virtual device is used in Microsoft Hyper-V in Windows 10, Windows Server 2016 and Azure. Most of this code was extracted from FreeBSD and some of this is from earlier code donated by Brocade.
Only Linux is supported at present, but the code is split to allow future FreeBSD and Windows support. This version works with upstream kernel (4.16) but in that mode only a single queue is supported. With additional patches that are pending for 5.0 kernel, multi-queue support works as well. Device binding is best done via driverctl; this required some additional fixes to kernel and driverctl to work correctly. Linux kernel vmbus support needed to support sysfs driver_override and driverctl needed to handle non-PCI bus from udev. https://gitlab.com/driverctl/driverctl/merge_requests/3 http://driverdev.linuxdriverproject.org/pipermail/driverdev-devel/2018-April/118889.html Stephen Hemminger (4): bus/vmbus: add hyper-v virtual bus support net/netvsc: add hyper-v netvsc network device net/netvsc: add documentation bus/vmbus and net/netvsc: add meson build support MAINTAINERS | 10 + config/common_base | 13 + config/common_linuxapp | 4 + config/meson.build | 7 + doc/guides/nics/index.rst | 1 + doc/guides/nics/netvsc.rst | 73 + doc/guides/rel_notes/release_18_05.rst | 6 + drivers/bus/Makefile | 1 + drivers/bus/meson.build | 2 +- drivers/bus/vmbus/Makefile | 36 + drivers/bus/vmbus/linux/Makefile | 3 + drivers/bus/vmbus/linux/vmbus_bus.c | 354 +++++ drivers/bus/vmbus/linux/vmbus_uio.c | 379 +++++ drivers/bus/vmbus/meson.build | 17 + drivers/bus/vmbus/private.h | 132 ++ drivers/bus/vmbus/rte_bus_vmbus.h | 400 ++++++ drivers/bus/vmbus/rte_bus_vmbus_version.map | 28 + drivers/bus/vmbus/rte_vmbus_reg.h | 344 +++++ drivers/bus/vmbus/vmbus_bufring.c | 241 ++++ drivers/bus/vmbus/vmbus_channel.c | 405 ++++++ drivers/bus/vmbus/vmbus_common.c | 286 ++++ drivers/bus/vmbus/vmbus_common_uio.c | 232 ++++ drivers/net/Makefile | 1 + drivers/net/meson.build | 2 +- drivers/net/netvsc/Makefile | 23 + drivers/net/netvsc/hn_ethdev.c | 760 ++++++++++ drivers/net/netvsc/hn_logs.h | 35 + drivers/net/netvsc/hn_nvs.c | 533 +++++++ drivers/net/netvsc/hn_nvs.h | 243 ++++ drivers/net/netvsc/hn_rndis.c | 1101 +++++++++++++++ drivers/net/netvsc/hn_rndis.h | 26 + drivers/net/netvsc/hn_rxtx.c | 1221 +++++++++++++++++ drivers/net/netvsc/hn_var.h | 140 ++ drivers/net/netvsc/meson.build | 13 + drivers/net/netvsc/ndis.h | 378 +++++ drivers/net/netvsc/rndis.h | 414 ++++++ drivers/net/netvsc/rte_pmd_netvsc_version.map | 5 + mk/rte.app.mk | 2 + 38 files changed, 7869 insertions(+), 2 deletions(-) create mode 100644 doc/guides/nics/netvsc.rst create mode 100644 drivers/bus/vmbus/Makefile create mode 100644 drivers/bus/vmbus/linux/Makefile create mode 100644 drivers/bus/vmbus/linux/vmbus_bus.c create mode 100644 drivers/bus/vmbus/linux/vmbus_uio.c create mode 100644 drivers/bus/vmbus/meson.build create mode 100644 drivers/bus/vmbus/private.h create mode 100644 drivers/bus/vmbus/rte_bus_vmbus.h create mode 100644 drivers/bus/vmbus/rte_bus_vmbus_version.map create mode 100644 drivers/bus/vmbus/rte_vmbus_reg.h create mode 100644 drivers/bus/vmbus/vmbus_bufring.c create mode 100644 drivers/bus/vmbus/vmbus_channel.c create mode 100644 drivers/bus/vmbus/vmbus_common.c create mode 100644 drivers/bus/vmbus/vmbus_common_uio.c create mode 100644 drivers/net/netvsc/Makefile create mode 100644 drivers/net/netvsc/hn_ethdev.c create mode 100644 drivers/net/netvsc/hn_logs.h create mode 100644 drivers/net/netvsc/hn_nvs.c create mode 100644 drivers/net/netvsc/hn_nvs.h create mode 100644 drivers/net/netvsc/hn_rndis.c create mode 100644 drivers/net/netvsc/hn_rndis.h create mode 100644 drivers/net/netvsc/hn_rxtx.c create mode 100644 drivers/net/netvsc/hn_var.h create mode 100644 drivers/net/netvsc/meson.build create mode 100644 drivers/net/netvsc/ndis.h create mode 100644 drivers/net/netvsc/rndis.h create mode 100644 drivers/net/netvsc/rte_pmd_netvsc_version.map -- 2.17.0
