<pre>I did another round of testing and am quite pleased with the results.
New setup:
<span class="quote">> # Host
> qemu: 2.10.0
> kernel: 4.13.5-gentoo</span >
<span class="quote">> # Guest:
> kernel: vmlinuz-4.13.6-1-default (OpenSUSE)
> cmdline: amdgpu.cik_support=1 modprobe.blacklist=radeon</span >
I did a couple of restarts and am quite pleased, that no host-hangups occured.
The chance of a successfull initialization of the graphics hardware within the
guest is at around 60%.
When it fails, the following line is always the last visible:
<span class="quote">> fb: switching to amdgpudrmfb from EFI VGA</span >
Additionally, even when everything works, there are a couple of ring test
errors:
<span class="quote">> [drm:gfx_v7_0_ring_test_ring [amdgpu]] *ERROR* amdgpu: ring 2 test failed (scratch(0xC040)=0xCAFEDEAD)</span >
I'll attach a new log-file showing the boot log when everything works.</pre>
