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

Status in The Linux Kernel:
  New
Status in QEMU:
  New

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 -device vfio-pci,host=02:00.0,x-vga=on \

  -spice port=5930,disable-ticketing

  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.
