Re: [Driver error: Code 43] Trying to GPU passthrough my IGD (Intel HD G

Hi,
I did run in a similar issue a few weeks ago. I don't have a solution, but maybe some of my experience is helpful.
After updating Windows 10 to build 1909 I got the error 43 for my passed-through GPU. It doesn't change with build 2004. I did changed the graphic card - no change. For testing purposes I did install a separate Windows 7 vm - and voila, GPU passthru was working! Thus I "believe" it must be a Windows 10 issue.
Now, I'm not a gamer, thus the power of a pass-thru GPU isn't important to me. More over I have passed-thru a sound card and a sata/usb card with pci pass-thru - both are working still fine.
I assume it is an issue with hypervisor detection of Windows 10 (wsl2 ?). VMware does have an option to hide a hypervisor for the guest. I couldn't check if this works. Does qemu have a similar option? I didn't found it.
Anyway, I would appreciate any further information. Unfortunately I don't have enough time to investigate further. It was a short dream to have Linux and Windows running at one time on one PC. 

regards
Kai

Scenario:

  *
Host bios firmware: Tried with pure UEFI firmware and with CSM enabled. 
  *
Virtual Machine scheme (xml)<https://pastebin.com/J0zZEvwm>
  *
CPU: Intel i5 4590T (Haswell) -> It doesn't have GVT-d nor GVT-g, so
I'm trying the legacy mode.
  *
GPUs:
1- Intel HD Graphics 4600(headless - no cable attached). Primary host GPU. 
2-RX580(HDMI cable connected). -> I'll keep this to the host.

Kernel parameters: intel_iommu=on iommu=pt efifb=off simplefb=off nofb
vfio-pci.ids=8086:0412,8086:0c0c

Things I tried:
1- Compile latest rc2 qemu.
2- /etc/modprobe.d/iommu_unsafe_interrupts.conf -> "options
vfio_iommu_type1 allow_unsafe_interrupts=1"
3- Set "pc-i440fx-2.2" to several versions.
4- Compile Seabios with some specific patch I found online.
5- /etc/modprobe.d/kvm.conf -> "options kvm ignore_msrs=1"
6- Set x-vga to "yes" and "no". I know it doesn't make difference on
legacy mode.
7- Some qemu arguments(e. g. -nographic) regarding graphics, setting
all those to off.
