That would be interesting to see indeed. Actually I bought the RX460
because first I wanted to use my old HD7850, but then my pc didnt even
want to boot (linux, didnt try windows). It just hanged seconds after
grub loading with a lot of those PCIe Bus Error's. Then I tried a couple
Nvidia NVS295's I had but I couldnt get them to work properly (driver
issues which caused mismatching colours).
Probably there is just something wrong with that MSI RX480, as it gave
those PCI-E Bus Error's also when it was the only GPU in my system
(while I was waiting for the RX460). But then again, it's strange that
the rom could be extracted correctly with GPU-Z under Windows.
I did a Unique Heaven test and the results where not bad, ~1350 points
and 53fps. But during some scenes it seemed the camera movement slowed
down and then sped up significantly a couple of times. It didnt look
like that was intentionaly but that said there was no drop in fps. Will
do some more tests tomorrow as I am also not yet really happy with the
sound quality (too much noise sometimes).
Yes, I extracted the uefi bios from
edk2.git-ovmf-x64-0-20170120.b2426.gaa961de.noarch.rpm. See xml below.
Cheers, Pim

I think you have a tougher time because you have two AMD cards. I am
able to blacklist the AMD driver completely because my "other card" is
Intel.
Are you using the uefi bios for your virtual machine?

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.

Here is my xml in case it helps:
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.
Kind rgds, Pim

In the mean time, do you know which bios revision your

The other revision is

So is it 113-MSITV341MH.151 or 113-MSITV341MH.152 ?

That's a simple question but a difficult

Anyway, I got the following results after
using GPU-Z
under Windows:
The RX480 is a MSI Gaming X 8G:
