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 v8 - targeted for 18.08, move release notes - use Ted's libuuid (not FreeBSD) because that is 3 clause BSD license versus 2 clause in FreeBSD - minor checkpatch whitespace fixes v7 - add EAL UUID functions from BSD to remove dependency on libuuid this means device can be enabled by default and eliminates build issues - add support for latest NetVSP protocol (from hayaingz) - add probe finish for compatability with 18.05 - rebase to 18.05-rc3 v6 - rebase to current 18.05-rc2 - fix RSS initialization - minor documentation fixes v5 - rebase to current 18.05-rc1 - fix message from vmbus due to race on sysfs for sub channel v4 - don't enable by default because of uuid library dependency - api's are internal no need to mark experimental - add netvsc ini file - fix MAINTAINERS entry v3 - fix documentation to format correctly and include more info about binding - fix build on 32 bit - minor white space and indentation fixes Stephen Hemminger (5): eal: add rte_uuid support 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 | 11 + config/common_base | 13 + config/common_linuxapp | 3 + config/meson.build | 7 + doc/guides/nics/features/netvsc.ini | 23 + doc/guides/nics/index.rst | 1 + doc/guides/nics/netvsc.rst | 103 ++ doc/guides/rel_notes/release_18_05.rst | 5 + 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 | 355 +++++ drivers/bus/vmbus/linux/vmbus_uio.c | 390 ++++++ drivers/bus/vmbus/meson.build | 16 + drivers/bus/vmbus/private.h | 132 ++ drivers/bus/vmbus/rte_bus_vmbus.h | 396 ++++++ 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 | 406 ++++++ 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 | 761 ++++++++++ drivers/net/netvsc/hn_logs.h | 35 + drivers/net/netvsc/hn_nvs.c | 535 ++++++++ drivers/net/netvsc/hn_nvs.h | 245 ++++ 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 | 139 ++ 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 + lib/librte_eal/bsdapp/eal/Makefile | 1 + lib/librte_eal/common/Makefile | 2 +- lib/librte_eal/common/eal_common_uuid.c | 193 +++ lib/librte_eal/common/include/rte_uuid.h | 129 ++ lib/librte_eal/common/meson.build | 2 + lib/librte_eal/linuxapp/eal/Makefile | 1 + mk/rte.app.mk | 2 + 45 files changed, 8260 insertions(+), 3 deletions(-) create mode 100644 doc/guides/nics/features/netvsc.ini 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 create mode 100644 lib/librte_eal/common/eal_common_uuid.c create mode 100644 lib/librte_eal/common/include/rte_uuid.h -- 2.17.0
