      @planedrop It shows up when I run LSCPI

        @ImThatFluffy Maybe try running a GPU load on it and installing Nvidia SMI to see if the GPU is being used?

          @planedrop I cant get the GPU to pull anything without it being in /dev/dri/ & its a intel ARC GPU SMI is going to be pretty pointless AFIAIK.

            @ImThatFluffy Oh yes, sorry, forgot this was an ARC GPU.

            Have you tried getting the ARC drivers installed? I imagine they should work if it shows up in lspci.

            I've never passed an ARC GPU through though so it's possible there's something additional needed to get it going.

              @planedrop All the correct drivers are loaded in the VM

              :/home/debian# sudo apt list --installed | grep intel

                Are you sure your device doesn't have another PCI address? (like some graphic cards got the GPU at a PCI address and the HDMI/sound to another, if you don't pass both the driver will fail to load)

                  LSPCI on the host shows this

                  84:00.0 VGA compatible controller: Intel Corporation Device 56a5 (rev 05)
85:00.0 Audio device: Intel Corporation Device 4f92

                  Im currently only passing 84:00.0 through I will attempt to pass 85:00.0 through as well and re update.

                    Yes, please hide both from the dom0 and pass both to the guest, start again and I think that might work 🙂

                      Passed 84 and 85 into the VM and still no luck.

                        Hmm that's weird 🤔 Anyone else around using an ARC card in passthrough?

                          @ImThatFluffy Have you installed the firmware for the card that your proposing to pass through? That way you can be sure that the card is fully functional.

                          I read in an article about getting the card working written during 2023 that it requires the firmware to be installed (present) on the Linux system along with the compatible drivers.

                          So you may be missing the firmware also is all parts of the Intel Arc drivers fully installed on the system for the device to fully function?

                            Yea im not sure, it was either an issue with the way I had Debian setup or compatibility things booted up Ubuntu 22.04LTS with the HWE kernel and it worked perfectly.

                              Well if you are using Ubuntu Linux 22.04.1 LTS or one of the later point releases then it would be using a Linux Kernel version 6.1 or later, when its a HWE kernel. So any bugs from earlier versions of the kernel would have been fixed, also the Intel ARC graphics hardware would have been released during one of the point releases. On the Debian Linux front a distribution version earlier than version 12.0 would have been unlikely to have complete properly functioning support, due to that release being the first one with the Linux kernel version of 6.1 or later.
