Intel ARC 310 Problem

chicagomed

New XCP-NG user so please forgive any obvious mistakes.

Two issues:

I have an Arc 310 on XCP-NG 8.3 I am trying to pass it through to a VM
but only the HDMI component is visible in PCIE-LIST or on XOA GUI.
I am able to pass that through.

I can see the Audio component in the system from Console but I can't get it
to show up in the XE commands/environment.
When passing throught the HDMI component to my VM (Arch Linux, up to date build)
I seem to be having a contention problem with the XCP-NG Cirrus driver. I have tried blacklisting
it/disabling it but without any luck. Wondering if anyone is having this problem (using Arch/Hyprland).

Thank you and looking forward to contributing to this community.

Can you do a lspci in the Dom0? I'm not sure the audio device is an adressable device (unlike Nvidia cards for example)

Enchanté @olivierlambert!

Thank you for the reply and this great product. I've followed you for a few years! A pleasure to be writing with you.

Here is the screenshot of the host. 0b appears both with XE and on the GUI.
0a (the audio) never makes it past the Dom0. I've read about various conditions where the Dom0 could hijack it but I haven't been successful in my trouble shooting.

Best Regards!

Hmm are you sure it's correctly ignored before trying to pass it trough? The success of PCI passthrough is only possible because it's hidden from the Dom0
