AMD RX6600 GPU passthrough works with Windows 11 driver but I can’t install AMD Adrenalin driver

[YAGA]

Hi there,

My setup: Asrock B550 ITX/AX with Ryzen 5950x + Asus RX 6600 with PVE 8.1.4 and Windows 11 with GPU passthrough.

Windows 11 device manager recognizes AMD Radeon RX 6000 and 32-core AMD 5950x (Qemu with CPU host and numa=1 parameters.

Everything seems to work properly with 3D acceleration based on Windows 11 RX 6600 driver.

I’m unable to install AMD Adrenalin driver because the driver didn’t recognise AMD hardware.

With 3DMark Time Spy, the CPU is not recognised but the demo works properly with good 3D results. I can’t upgrade 3DMark to latest version because my CPU is recognised as a non-SSSE3 compatible.

What is wrong in my setup?

Hi,

Haven't had a response yet. Should I consider that it is common not to be able to install the AMD Adrenalin driver with GPU passthrough?

Kind regards,

In the past AMD drivers did not work for me with Machine Version 8.1 but did work with 7.2. I don't know how Windows 11 responds to such a change (backup or clone it) but you might want to give it a try.

Thanks @leesteken, I've tried machine pc-q35-7.2 but without success, 3D acceleration still working with Windows driver for RX 6600 but I can't install AMD Adrenalin driver (AMD hardware is not recognised).

Hi, I met same problem as yours. Here is my solution.
Don't use the driver installer below. This installer will check you hardware. Try directly install gpu driver matching you gpu.



Here is the link of lastest RX6600 driver: https://www.amd.com/en/support/down...radeon-rx-6000-series/amd-radeon-rx-6600.html
Hope this will help.

I had the same issue but with the rx560. Originally, I used "non-whql-radeon-software-adrenalin-2020-21.2.3-win10-64bit-feb22" which would work with Spice. But I could not install any newer drivers nor Arenaline.
My solution was :

1. VM > Hardware > Display > Graphic Card: none
2. Install AMD Adrenaline (amd-software-adrenalin-edition-24.4.1-minimalsetup-240423_web) using a physical monitor
3. Shutdown the VM
4. VM > Hardware > Display > Graphic Card: VMware compatible
   1. Memory: 36 (Optional)
   2. Clipboard: Default

AMD Adrenaline does not work with Spice. I hope this is helpful.
