Gpu passthrough on Asrock rack B650D4U3-2L2Q will not work
-
When I try to take Gpu passthrough with a gtx 1070ti on an Asrock rack B650D4U3-2L2Q motherboard with windows 10. I get the drivers installed fine without errors but after reboot I get an error triangle in the windows device manager-. error43 and no image on the screen
have Iommu and svm enabled in the bios
Wasn't Xcp-ng 8.3 related or windows drivers I think.
Tested with another PC with Xcp-ng 8.3 and everything worked immediately. So think it must be Asrock rack B650D4U3-2L2Q bios related or ipmi trying to use the same gpu.
Have even copied working win vm from the other pc that this worked on that it worked on and started the same error.
Also tried an old Radeon HD 5450 with which everything worked as it should and got a picture on the screen

Hi,
Check all your BIOS settings first.

@olivierlambert Hi, I have tried but it is not easy to find things in an Asrock bios. But have enabled svm and Iommu. Are there more things I need to enable?
Is an amd ryzen 9 9950x Cpu -
BIOS is up to date?
-
@olivierlambert Yes but is beta bios to support the new Amd Ryzen9000 series. But there may be some bugs in the bios,
I think the motherboard was launched after April this year. First bios slip 27/7/2024.
I have contacted Asrock support, But there are so many links that the error could lie in.
But there are several with B650D4U3 motherboards that have the same error
-
Yeah, I have the impression it's a buggy motherboard. Let's see if at some point you can manage to get it working Keep us posted!
-
@olivierlambert Yes, I hope so . I don't need so many cpu cores if I don't have any ext gpu
Is it the bios that determines which screen the xcp-ng console should be displayed on?
As soon as I choose passthrough enable, I lose this image on the screen associated with the ext video card.
But it doesn't come back on any of the other screens connected to the motherboard, nor does ipmi show this xcp-ng console.
even though I have selected primary video adapter to int graphics in the bios.
This is the main difference on the Radeon HD 5450 that gpu passthrough worked with. There, the primary video adapter remained on the graphics section of the motherboard.So one suspects that this choice in the bios does not work.
The strange thing is that normal pci passthrough works as it should on both m.2 and pci usb controller card
Asrock suport wanted to try to reproduce the error with them but have no idea if they will choose to use Xcp-ng and xen orchestra. It takes quite a long time to set everything up
-
Tell them that if they want "assistance" to reproduce, we are keen to discuss directly with them

@olivierlambert Got it working with proxmox now by hooking on an option (PCI-Exspress).
can one address that there is a pci-e device in the same way in Xcp-ng with a command line?
As soon as I removed this option it stopped working and I got the same error 43 back
