Unfortunately no, but I have to start the windows vm that uses the rx480
before I can use atiflash for linux. Not sure whether I use the correct
terminology, but it seems the bios of the gpu needs to be
initialized/loaded before atiflash can access the gpu. If I try to use
AtiWinFlash in the windows vm I get an Invalid rom error.
By the way, I spoke too soon about the PCIe Bus Errors. It looks that
yesterday my syslog daemon froze and therefor I didnt see them anymore
(oops ;). Today I got them again in plenty fold.

Follow-up on the issues I was experiencing, it looks like they are
fixed by a new bios I got from MSI:

With this bios my PCIe Bus Errors are gone and I don't need to
specify the rom file in the xml anymore.
Not sure if this is known to everyone, but I had some problems
with the atiflash tool under linux as it did not recognise my
RX480. It seems that this was because the RX480 rom's needs to be
initialized before atiflash can access it. So in my case I needed
to start my Windows virtual machine before atiflash recognised my
card.

depending on the Polaris being a reference card
Thanks for your comments, but it seems the MSI Gaming X series
is not a reference card (its factory overclocked).
So the vBios being bricked by the manufacturr should be
also kept in mind.
I dont think this is the case here, as using GPU-Z under
Windows shows a valid EFI rom. It seems a Linux issue only, I
have submitted a case with MSI to see what they say.

Thanks, if I add the rom (the one I saved using GPU-Z under
Windows) my display turns on.
Unfortunately it didnt work then yet, as my dmesg was flooded
with the following message:
vfio-pci 0000:01:00.0: BAR 0: can't reserve [mem
0xc0000000-0xcfffffff 64bit pref]
This was caused due grub loading vesafb for the RX480 as the
graphical terminal was enabled. So in /etc/default/grub I had
to add GRUB_GFXPAYLOAD_LINUX="text" and disable 'GRUB_GFXMODE'
(not sure about the last one as maybe thats implicit but it
doesnt hurt either).
Unfortunately that does mean I cant use ddccontrol it seems,
as that complains about missing a framebuffer driver.
Therefore I've also asked Asus whether they plan to support
choosing the primary vga slot like Gigabyte does and they said
'they will discuss this internally'.
My Asus support agent actually had never heard of vfio before
and repeatedly said that Asus only supports multiple GPU's
when using SLI/Crossfire. So maybe if more people would
contact their local Asus support agent and request this
feature they are more willing to look at it? Who takes the
hint? ;)
I had to install the driver twice as the first time the
install failed, but at the moment the GPU appears to be
working correctly. Now first on to sound before I do some 3D
testing.

In the mean time, do you know which bios revision
your card has?
The other revision is
https://www.techpowerup.com/vgabios/185395/msi-rx480-8192-160719
<https://www.techpowerup.com/vgabios/185395/msi-rx480-8192-160719>
So is it 113-MSITV341MH.151 or 113-MSITV341MH.152 ?

Its likely that

update may
fix your RX 480 card. Do both cards
work under a pure
Windows
environment?
That's a simple question but a difficult
answer to get a
pure
Windows environment working again ;)
Anyway, I got the following results after
using GPU-Z
under Windows:
The RX480 is a MSI Gaming X 8G:
