Title:
  [Hyper-V] PCI Passthrough prerequisites

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Xenial:
  Fix Released

Bug description:
  Jake Oshins (Microsoft) has submitted upstream the PCI Passthrough
  feature, and while it is not yet accepted upstream (because of the
  effect on multiple trees and affects PCI), Microsoft would like
  Canonical to consider its inclusion in Ubuntu 16.04 and beyond. The
  rounds of feedback on the patches are winding down, so it is a good
  time to consider them.

  All of the submitted files are in the attached thread, but not all are
  committed to Linus's tree as of 4.5-rc1.

  This feature is needed for supporting SR-IOV and GPU passthrough on
  Hyper-V.

  The 10th iteration of the upstream submission is available on lkml:

  https://lkml.org/lkml/2015/12/10/553

  Subject	[PATCH v10 0/7] PCI: hv: New paravirtual PCI front-end for Hyper-V VMs
  Date	Thu, 10 Dec 2015 17:52:56 +0000
  From: Jake Oshins <jakeo@xxxxxxxxxxxxx>

  This version of the patch series removes warning when compiling x86
  32-bit while still making it build cleanly for x64.

  First, export functions that allow correlating Hyper-V virtual processors
  and Linux cpus, along with the means for invoking a hypercall that targets
  interrupts at chosen vectors on specific cpus.

  Second, mark various parts of IRQ domain related code as exported, so that
  this PCI front-end can implement an IRQ domain as part of a module. (The
  alternative would be to pull all tyhis into the kernel, which would pull
  in a lot of other Hyper-V related code, as this IRQ domain depends on
  vmbus.ko.)

  Third, modify PCI so that new root PCI buses can be marked with an associated
  fwnode_handle, and so that root PCI buses can look up their associated IRQ
  domain by that handle.

  Fourth, introduce a new driver, hv_pcifront, which exposes root PCI buses in
  a Hyper-V VM. These root PCI buses expose real PCIe device, or PCI Virtual
  Functions.

  Jake Oshins (7):
    drivers:hv: Export a function that maps Linux CPU num onto Hyper-V
      proc num
    drivers:hv: Export hv_do_hypercall()
    PCI: Make it possible to implement a PCI MSI IRQ Domain in a module.
    PCI: Add fwnode_handle to pci_sysdata
    PCI: irqdomain: Look up IRQ domain by fwnode_handle
    drivers:hv: Define the channel type of Hyper-V PCI Express
      pass-through
    PCI: hv: New paravirtual PCI front-end for Hyper-V VMs
