[Solved] Passthrough card graphic vega8

lolop · 2020-04-12 21:05:27

Hello,

I have 2 gpu on my machine:
lspci -nn | grep VGA
01: 00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD / ATI] Baffin [Radeon Pro WX 4100] [1002: 67e3]
09: 00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD / ATI] Raven Ridge [Radeon Vega Series / Radeon Vega Mobile Series] [1002: 15dd] (rev c8)

I have configured my system to use passthrough on the vega chipset:
sudo dmesg | grep -i vfio
[7.615963] VFIO - User Level meta-driver version: 0.3
[7.627976] vfio-pci 0000: 09: 00.0 : vgaarb: changed VGA decodes: olddecodes = io + mem, decodes = io + mem: owns = none
[7.646875] vfio_pci: add [1002: 15dd [ffffffff: ffffffff]] class 0x000000 / 00000000
[13.130571] vfio-pci 0000: 09: 00.0: vgaarb: changed VGA decodes: olddecodes = io + mem, decodes = io + mem: owns = none

lspci -nnk -d 1002: 15dd
09: 00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD / ATI] Raven Ridge [Radeon Vega Series / Radeon Vega Mobile Series] [1002: 15dd] (rev c8)
Subsystem: ASUSTeK Computer Inc. Raven Ridge [Radeon Vega Series / Radeon Vega Mobile Series] [1043: 876b]
Kernel driver in use: vfio-pci
Kernel modules: amdgpu

I configured a guest with virt-manager by adding the card in question and deleted QXL and spice.

Already when I start the guest my machine is slowed down I pers the use of my Corsair Gaming SABER mouse via daemon ckb-next.
In short, I plug another mouse into USB and switch the screen connected to the Vega chipset, but there is nothing.
And the pc starts to crash and I can't find a log.

Do you have any tracks to explore?

Thank you

I come to clarify with a dmesg which gets carried away at the launch of the vm:

Full dmesg and/or journal please .

output of the script mentioned at https://wiki.archlinux.org/index.php/PC … _are_valid

Are both of your cards discrete videocards ?
What is brand, model and firmware version in use on your system / motherboard ?

lolop · 2020-04-19 08:37:03

the problem came from using the IGPU vega 8 which is integrated into the processor.
I did the passthrought that the pci graphics card that I had in addition without problem.

Yup, passing through an iGPU is technically possible but depends on processor , motherboard and chipset manufacturers to have things setup correctly to achieve it.
Usually atleast one of them (often all three) overlook something that is essential to make passing through an iGPU work.

Please prepend [Solved] to the thread title (edit first post) .
