ASRock X570 Steel Legend iommu groups

[lixaotec]

hey there fellow,

do you know if this MB iommu groups are very isolated for pcie?

I plan to use 4 GPU one each x1 pcie and a x16, and for the fifth x16 i plan to use a usb 4 port pcie with 4 controller to passthrough to 4 vms, like creating a 4 multiseat computer.. with proxmox.

Do you think its possible with that motherboard?

thanks
