How to passthrough AMD R9 5900HX iGPU in PVE 7.2?

[Pandaaaa906]

it got code 43 in Device Management.
in some tutorials, they say it would be fine, after installing the gpu driver.
but when i installing AMD driver, it got Error 184

it seems the error 184 has nothing to do with passthrough but with outdated windows? https://www.amd.com/en/support/kb/faq/gpu-kb184

I have the same problem, but have tried with the latest driver and Windows version.



Does anyone have a solution to this?

Watching. I'd like to be able to passthrough the graphics to both Linux and Windows VMs--though not at the same time, of course.

the same problem, as in you get error 184 on driver installation?

 

[leesteken]

Can you boot that VM with a Ubuntu installer LiveCD? Not to install Ubuntu, just to see if the desktop environment of the installer shows on a display connected to the GPU. Recent Ubuntu versions come with Linux drivers and should just work. That would be a good test to see if the passthrough is configured correctly.

I finally solved the problem, thanks to @Naunter from other forum

the most important key is the bios supports gpu passthrough or not, my device is Morefine s500+
and the next key is vbios file, as attached.
extract the rom file and copy to pve host /usr/share/kvm/cezanne.rom

*** even it seem worked, but it still has vendor reset problem ***
i cannot individually reboot that win10 vm, which will cause whole host break down

PS: In "/etc/default/grub"，Not sure that every option is useful, some might be outdated options

u could check this video it's chinese but might help
