Try these:

git://github.com/awilliam/linux-vfio.git vfio-vga-reset
git://github.com/awilliam/qemu-vfio.git vfio-vga-reset

When using both this kernel and this qemu, we'll do a PCI bus reset,
which should give you much more consistent behavior both between
instances of the guest and at guest reset.

  Qemu 1.5-git gpu clock control doesn`t work after guest reboot

Status in QEMU:

Bug description:
  I run qemu from git with such command:

  qemu-system-x86_64 -nodefaults -m 4096 -smp 8,cores=4,threads=2,sockets=1 
-cpu 'kvm64' -device usb-mouse -M q35 -vga qxl -no-hpet -boot once=c,menu=on

  Before guest (Windows 7) reboot, videocard works in 3D mode with full
  frequency. But after reboot videocard works in 3D only with powersafe
  frequency. Then I must reboot host for recover gpu clock control.
