Subject: [dpdk-dev] [PATCH v3 0/4] Hyper-V Netvsc PMD
Date: Tue, 17 Apr 2018 14:53:20 -0700	[thread overview]
Message-ID: <20180417215324.8576-1-sthemmin@microsoft.com> (raw)

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.

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 (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
