Cant Pass trough USB controller with same pci ids on different IOMMU Groups

[hygoggx]

So i want to pass trough my USB controller on my asrock x570 steel legend motherboard to win 10 VM, but the pci id is present in another IOMMU group

 

...

IOMMU group 28:

[1022:1485] 0a:00.0 Non-Essential Instrumentation [1300]: Advanced Micro Devices, Inc. [AMD] Starship/Matisse Reserved SPP

[1022:149c] 0a:00.1 USB controller: Advanced Micro Devices, Inc. [AMD] Matisse USB 3.0 Host Controller

[1022:149c] 0a:00.3 USB controller: Advanced Micro Devices, Inc. [AMD] Matisse USB 3.0 Host Controller

...

IOMMU group 33:

[1022:1485] 0f:00.0 Non-Essential Instrumentation [1300]: Advanced Micro Devices, Inc. [AMD] Starship/Matisse Reserved SPP

[1022:1486] 0f:00.1 Encryption controller: Advanced Micro Devices, Inc. [AMD] Starship/Matisse Cryptographic Coprocessor PSPCPP

[1022:149c] 0f:00.3 USB controller: Advanced Micro Devices, Inc. [AMD] Matisse USB 3.0 Host Controller

[1022:1487] 0f:00.4 Audio device: Advanced Micro Devices, Inc. [AMD] Starship/Matisse HD Audio Controller

 

My goal is to bind all pci on IOMMU group 33

 

I tried using xen-pciback.hide but the VM failed to start

 

I tried also using new vfio-bind method using config file with no luck

 

heres my syslinux.cfg

default menu.c32
menu title Lime Technology, Inc.
prompt 0
timeout 50
label Unraid OS
  menu default
  kernel /bzimage
  append iommu=pt rcu_nocbs=0-15 xen-pciback.hide=(0f:00.3)(0f:00.4) pcie_acs_override=downstream vfio_iommu_type1.allow_unsafe_interrupts=1 initrd=/bzroot
label Unraid OS GUI Mode
  kernel /bzimage
  append iommu=pt rcu_nocbs=0-15 pcie_acs_override=downstream vfio_iommu_type1.allow_unsafe_interrupts=1 initrd=/bzroot,/bzroot-gui
label Unraid OS Safe Mode (no plugins, no GUI)
  kernel /bzimage
  append initrd=/bzroot unraidsafemode
label Unraid OS GUI Safe Mode (no plugins)
  kernel /bzimage
  append initrd=/bzroot,/bzroot-gui unraidsafemode
label Memtest86+
  kernel /memtest

heres my config/vfio-pci.cfg file

BIND="0f:00.3 0f:00.4 0f:00.0 0f:00.1"
