[vfio-users] issues about igd and usb passthrough when windows7 safe mode interface occurs

[fulaiyang]

Hi,Alex
    Recently, I bought another platform with  i3-6100U to passthrough the GPU. The platform has only DP or HDMI output. I am very happy to success to passthrough igd and the usb controller. However, when the windows7 safe mode interface happens, the GUI is divided into three parts. And the keyboard is invalid. After the windows7 desktop occurs, the GPU and usb devices can run very perfectly. Did you meet this problem?


environment :
Intel Core i3-6100U @ 2.30GHz
Intel Corporation Sky Lake Integrated Graphics 
Intel Corporation Sunrise Point-LP USB 3.0 xHCI Controller
DP output
Ubuntu 16.04 LTS DESKTOP
Host kernel 4.7.2 x86_64 GNU/Linux
qemu 2.7.0

/boot/config-4.6.6
