I installed Windows 8 with VFIO_PCI_VGA, vfio-vga-reset branches and
"-vga none -device vfio-pci,host=02:00.0,x-vga=on" I received an error:
"qemu-system-x86_64: Attempt to reset PCI bus for VGA support failed
(Inappropriate ioctl for device). VGA may not work." on start.
Then I installed the catalyst drivers. I started the Valley benchmark
and the video card is working in normally 3D mode. After rebooting the
host system does not hang, but in guest graphics card was in powersafe
mode with 100 mhz GPU and 300 mhz memry clocks.

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

-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.
