I have been using it for several months with the following settings and have not encountered any problems.

Due to a bug in vfio, the latest kernel is required.

It is not necessary to specify vBIOS. Perhaps it is not a ROM that should be specified.
Specifying disable_idle_d3=1 will cause the problem to worsen.

There will be no problems even if you restart or shut down the virtual machine.
When the virtual machine is stopped, amdgpu is used, but when it is started, vfio-pci is used.

^^^^^^^^^^^^^^thank you very much^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
But after enabling Hyper-V, the VM cannot be started,After many attempts, using

args: -cpu host,+vmx,+ssse3,+sse4.1,+sse4.2,+aes,+xsave,+xsaveopt,+xsavec,+xgetbv1,+xsaves,+avx,+avx2,+fma,+bmi1,+bmi2,+invtsc,+pdpe1gb,+tsc-deadline,hv_passthrough,-hypervisor,level=30,-waitpkg

like:

qm set 124 -args '-cpu host,+vmx,+ssse3,+sse4.1,+sse4.2,+aes,+xsave,+xsaveopt,+xsavec,+xgetbv1,+xsaves,+avx,+avx2,+fma,+bmi1,+bmi2,+invtsc,+pdpe1gb,+tsc-deadline,hv_passthrough,-hypervisor,level=30,-waitpkg'
qm set 124 -hookscript local:snippets/rx9070_reset.sh
qm set 124 -hostpci0 0000:da:00,pcie=1,rombar=0

I hope this helps others who have the same idea.
