[vfio-users] BSOD with IGD passthrough (HD4000/4600)

[Daimon Wang]

Hi,    I'm trying IGD passthrough with both Intel HD 4000 and HD 4600. Everything is fine, the Win7_64 VM start successful with Intel driver installed, and Aero is enabled. However when I run PCMark05 or any real 3D wallpaper (windows 3D bubble is fine), I got a BSOD with " SYSTEM_SERVICE_EXCEPTION" from (IGDKMD64.SYS(code 3B).    Is this a know issue or I'm missing any settings? (Since I got Aero enabled, most of basic settings should be ok)

    BTW, the NVidia passthrough works fine with PCMark05 on the same env as HD4600.

    My brief setup:
    1. i5 3317U HD 4000 + Ubuntu 16.04 + Qemu v2.8.0-rc0 from git + Kernel 4.8.9.
    2. HD 4600 + Fedora 25 + Qemu 2.7 from fedora. (NVidia passthrough works)

Regards,Daimon
