Issue to load gpu passthrough "Invalid PCI ROM header signature: expecting 0xaa55, got 0x4556"

[olivierlambert]

Hi,

Just to be sure I understand, you are trying to pass a non-discrete GPU to the VM, right?

[gleveque]

@olivierlambert hi, yes i try to use the ryzen igpu on a VM to use h264 decoding.

@gleveque @olivierlambert Is there any update on this topic?

Am curious as am seeing the same exact behavior with Ubuntu 24.04.1 on a Beeline EQR6 with a Ryzen 9 (6900HX + 680M iGPU).

What would be the best option to pass through the iGPU from Dom0 to a VM?

@itnok I'm sure you already have, but have you ensured that everything in this guide was done?

[itnok]

@nick-lloyd thanks, I did! Passthrough for AMD consumer Hardare iGPUs seams not to properly function… or, I should say, the Linux VMs are experiencing troubles correctly dealing with it: the devices are correctly passing down to the VM, but for some reason the ROCm kernel module is not capable of dealing with them. Could it be be ause it expected them to be on a specific bus? (They are assigned a different bus id)
Could it be because it expected them to be under the same bus id? (They are scattered around different dedicated bus ids)
Not sure, but the end result is the iGPU cannot be correctly initialized, albeit detected.

@itnok hey, did you ever get this working? I am in a similar position now with the ROM header.

[itnok]

@DustyArmstrong Stopped trying, but that does not eventually mean it's now supposed to work: just lost interest and moved on with another product/solution entirely.

[DustyArmstrong]

@itnok fair enough and understandable, thanks for taking the time to reply.

@DustyArmstrong

The only GPU I've ever tried was nvidia quadro series, and that was probably under 8.2.

@Greg_E Thanks, I've got another thread up and it's potentially being addressed!
