AMD S7150-S2 passthrough don ' t work

[esro12056]

I want install tow AMD 7150-S2 Cards. The cards should only work as passthrough not vdi - so that I can support 4 vms.





/etc/modeprobe I use the files:
blacklist.conf
blacklist radeon
blacklist nouveau
blacklist amdgpu
#blacklist nvidia*


iommu_unsafe_interrupts.conf
options vfio_iommu_type1 allow_unsafe_interrupts=1


pve-blacklist.conf
blacklist radeon
blacklist nouveau
blacklist amdgpu

#blacklist nvidia*

/etc/default/grub
I modify to this …

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on intel_iommu=pt"


I do :
update-initramfs -u -k all

update-grub

Check:
lspci -nnk

We see the two Cards - there have 4 gpus because S2 cards
lsmod | grep vfio
vfio_pci 16384 1
vfio_pci_core 86016 1 vfio_pci
irqbypass 12288 3 vfio_pci_core,kvm
vfio_iommu_type1 49152 1
vfio 57344 7 vfio_pci_core,vfio_iommu_type1,vfio_pci
iommufd 77824 1 vfio

After rebbot

I built the card in the vm as pci …







Und dann bleibt die Maschine stehen…..

Mit der Änderung der Option auf:

funktionierte es auch nicht...



Proably it exist a functional introduction. I don t know what I do wrong.

Please let me know if someone has find a solution for the AMD S7150 with passthrough only.

Thanks
