Re: [vfio-users] Dual monitor with spice display + hdmi

[Daimon Wang]

Yes, I can confirm that a PC with on-board Intel card and an NV card can be 
configured for dual-monitor, with Aero on. And I can make a video window across 
both screen.However, I haven't success with Linux host. I've read in another 
thread that you can start 2 X server, each for one card.
While for VM, the qemu pass-through readme said IGD card can be the secondary 
card for calculation only (so no output). This mode is named "Universal 
Pass-Through", so maybe the NV card in this mode will have the same behavior?

A real life example of this is a motherboard with onboard video coupled with a 
discrete GPU in a slot.  As long as the onboard isn't disabled, they can work 
in tandem, at least for software rendering.  From what I understand, as well, 
DirectX 12 and Vulkan both support hardware rendering with multiple GPUs of 
different brands.

That's an interesting scenario ... How does Windows handle multiple graphics 
cards? Like, let's say this was all bare metal, and the machine had 2 different 
models of nVidia cards and an ATI card, with a monitor connected to each card. 
Would Windows be able to display a desktop on each monitor, or span a single 
contiguous desktop across them? If yes then I'd guess that what you're asking 
is at least theoretically possible, though I've never tested personally.

DID work, but it caused (about 75% of the time) Nvidia code 43 issues for me.  
But it definitely did work outside of that.

Is it possible for a guest VM to use both spice server graphics with

(windows 10 in this case) see it as a dual-monitor setup?

Has anyone tried this or gotten it to work?

Re: [vfio-users] amd rx480 invalid rom contents

[P. Pronk]

Thanks, that's good to know and I will try to specify the rom.

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


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

I noticed you don't have the vendor_id args in the hyperv area

I have that msi rx480 card working with pass through.

Note I had a much easier time using the uefi bios. I am currently
specifying a rom file in my XML for my video card but I don't think that's
entirely necessary.

How to debug it and make it run?

This is unrelated to your problem, but thank you very much for
mentioning this software. I was not aware of ddc/i2c or ddccontrol
before. After some tinkering i came up with full software kwm switch for
VMs
.
Hope it will be useful for ya people.
