Title:
  [FFe] Enable DDW on qemu aiming GPU passthrough performance on Ubuntu
  KVM

Status in qemu package in Ubuntu:
  In Progress

Bug description:
  == Comment: #0 - Breno Henrique Leitao <brenohl at br.ibm.com> - 2016-02-04 10:48:25 ==
  This is a feature to track DDW support on Qemu/kvm passthrough. This is a feature to improve performance when using GPUs on virtual machines.

  The kernel pieces are already on version 4.2, and now we need the
  pieces on qemu.

  This should be sent upstream in 2 weeks, and submission URL pasted
  here.
