iGPU PCI passthrough: new experimental packages need testers
-
@ovicz with the new edk2 package it should help your VM access the vbios in the rom bar.
Does the VM see the gpu?
Can you share the VM dmesg as attached file?
Also, are you trying to passthrough a sriov virtual function? or the entire physical gpu?
Thanks -
Yes it does see it.
dmesg.txt
Passthrough was working and without that file from your repo. -
@ovicz It seems your gpu works even without vbios since in your dmesg I can see
[ 7.424250] i915 0000:00:08.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0x0000 [ 7.424259] i915 0000:00:08.0: [drm] Failed to find VBIOS tables (VBT)So you're saying that anyway your setup was working even without all those new packages?
Thanks for testing anyway! -
@yannsionneau Yes it works with the stock packages.
-
@ovicz Thanks a lot for the feedbacks and tests
-
@yannsionneau No problem.
-
@yannsionneau Yes it works
Thank you very much, great job Tested on Ryzen 9 9950X / AMD Raphael iGPU Tested the new experimental iGPU passthrough packages. - CPU: AMD Ryzen 9 9950X - iGPU: AMD Raphael (1002:13c0) - XCP-ng: 8.3 -
Guest: Bazzite AMD - VBIOS: extracted from the ACPI VFCT and supplied as /root/vbios.bin - iGPU passthrough: working - AMD amdgpu driver: working - Physical HDMI output: working - Bazzite desktop displayed successfully on the physical HDMI port. Ubuntu 24.04.2 was able to initialize the GPU and Vulkan/RADV detected the Raphael iGPU, but the HDMI output went black when the graphical desktop started. Bazzite worked and provided a stable display output. So on my Ryzen 9 9950X, the experimental packages appear to successfully enable Raphael iGPU passthrough and physical HDMI output.

@steff22 Good news! And thanks a lot for the test! Could you share the guest VM dmesg please? as well as the lspci -n -vvv -s SBDF of the GPU?
Also, was it working with the stock xcp-ng packages? -
Y yannsionneau referenced this topic
-
@yannsionneau I updated XCP-ng with the iGPU PoC packages.
